Detailed Implementation

It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

This application provides a solution to the technical problem of damage to foldable screens due to improper use in related technologies.

The main solution of this application embodiment is: during the physical form switching process of the screen of the electronic device, determine the pressure position of the screen; when the pressure position of the screen is located within a preset area, output an abnormal operation reminder.

The solution provided in this application embodiment can continuously identify abnormal operation behaviors during the folding or unfolding of an electronic device screen. Once an abnormal operation is detected, an alert is issued so that the user is aware of the risk of screen damage and can stop the risky operation. By setting a preset area, the solution can accurately identify pressure operations in areas of the screen that are more easily damaged by pressure, thus avoiding finger pressure on the screen during folding. This reduces the risk of damage to the folding screen and extends its lifespan.

In the embodiments of this application, for ease of description, the following description uses an electronic device as the execution subject.

An electronic device is a terminal device with data processing, network communication, and program execution functions, such as a mobile phone, tablet computer, laptop computer, wearable device, and vehicle terminal. The following description uses a mobile phone as an example to illustrate the embodiments of this application and the various embodiments or implementation methods described below.

Based on this, this application provides an abnormal operation reminder method. Referring to Figure 1, Figure 1 is a flowchart illustrating the first embodiment of the abnormal operation reminder method provided in this application. This abnormal operation reminder method is applied to an electronic device with a foldable screen. The abnormal operation reminder method includes steps S10 to S20:

Step S10: During the physical form switching process of the screen of the electronic device, determine the pressure position of the screen.

The screen of an electronic device can be made of flexible materials, such as a flexible display screen, which is foldable. As an example, taking a mobile phone as an example, Figure 2 shows a schematic diagram of the external structure of an electronic device 100. The electronic device 100 includes a screen 110 and a casing 120 (not shown in Figure 2). The screen 110 is foldable, commonly known as a foldable screen, and the electronic device 100 can be called a foldable screen mobile phone. For example, the flexible display screen used in the screen 110 can be an OLED (Organic Light-Emitting Diode) display, an AMOLED (Active-Matrix Organic Light-Emitting Diode) display, a Micro LED (Micro Light-Emitting Diode Display), etc. These flexible display screens use flexible materials as substrates and are foldable.

Both the unfolded and folded states are physical forms of the screen. The screen can switch from an unfolded state to a folded state, and vice versa; this switching process is a physical form switching process. For example, an electronic device may include two or more screens, enabling dual-screen or multi-screen folding. Any two screens can switch physical forms, including in the unfolded state where the two screens are combined to form a larger screen, and in the folded state where the two screens overlap to reduce the space occupied by the electronic device. Another example is an electronic device that may include a single screen, which can be divided into two or more sub-screens. Any two sub-screens can switch physical forms, including in the unfolded state where they directly present as a single large screen, and in the folded state where the two sub-screens overlap to achieve the folding of the screen.

For example, Figure 3 shows a schematic diagram of the unfolded screen of an electronic device, and Figure 4 shows a schematic diagram of the folded screen of an electronic device. Based on the mobile phone in Figure 2, its screen 110 is divided into upper and lower screens. When the screen 110 is unfolded, as shown in Figure 3, it is a single screen; when the screen 110 is folded, as shown in Figure 4, the folded screen is folded inwards, and the two screens overlap. In Figures 3 and 4, for example, the outer casing 120 is set to correspond to the number of screens, that is, the screen 110 is divided into upper and lower screens, and the outer casing 120 is also divided into two parts accordingly.

The pressure-affected position on the screen refers to the location of the point of contact between the finger or object and the screen when the screen is pressed by a finger or squeezed by a foreign object. For example, an electronic device can receive the coordinate data of the contact point based on the screen's touch function, and then identify the position of the contact point based on this coordinate data to obtain the pressure-affected position. Another example is that the electronic device can detect pressure data based on a pressure sensor or pressure sensing matrix located below the screen, and then identify the position of the contact point based on this pressure data to obtain the pressure-affected position.

In related technologies, although a cover plate can be placed on top of a flexible display screen, made of flexible materials or ultra-thin glass, its function is to protect the flexible display screen. However, in reality, these cover plates cannot effectively protect the flexible display screen itself. When the screen surface, i.e., the cover plate surface, is subjected to heavy pressure, or when there are hard foreign objects on the screen or cover plate when the cover is closed, the screen can easily be squeezed and damaged, resulting in damage such as colored bright spots or black spots on the flexible display screen underneath. Therefore, it is necessary to detect abnormal operations that can easily damage the screen and thus the flexible display screen, especially abnormal operations during physical form switching. Because physical form switching operations require more force, the screen is subjected to greater pressure, making it more susceptible to damage to the flexible display screen.

Therefore, the embodiments of this application determine the screen pressure position during the physical form switching process of the electronic device screen, specifically including directly determining the screen pressure position when the electronic device screen is switching to a folded state or switching to an unfolded state.

Since the risk of screen damage is higher during physical form switching, step S10 is performed to realize screen pressure detection. This can promptly identify screen pressure caused by abnormal user operation during physical form switching, determine the screen pressure location, and provide timely abnormal operation reminders.

Step S20: When the screen is under pressure within a preset area, output an abnormal operation alert.

A preset area refers to a pre-defined area of the screen that is prone to damage. The preset area can be the entire screen or a portion of the screen, such as the center or lower-middle section. When an electronic device has multiple screens, the preset area can be the overlapping area of the screens when they are folded, or the area at the joint where the screens are spliced together, or a certain range on either side of the joint. When an electronic device has one screen, and that screen comprises multiple sub-screens, the preset area can be the overlapping area of the sub-screens when folded, or the area at the screen boundary, or a certain range on either side of the boundary. The choice is based on need and is not limited here.

In some feasible embodiments, the preset area is the overlapping area of at least two screens in a folded state.

When an electronic device has two screens, the folding of the two screens can be inward or outward. Regardless of the folding method, there will always be an overlapping area after folding. This overlapping area can be used as a preset area. In this case, the preset area may be the entirety of both screens (the two screens completely overlap after folding), or it may be the entirety of one screen and a portion of the other screen (the two screens partially overlap after folding). When an electronic device has multiple screens, such as three screens arranged in sequence as an upper screen, middle screen, and lower screen, if the upper and middle screens are foldable, but the middle and lower screens are not foldable, then the preset area is the overlapping area of the upper and middle screens after folding. In this case, the preset area may be the entire upper screen and the entire lower screen (the upper and lower screens completely overlap after folding), or it may be the entire upper screen and a portion of the middle screen (the upper and lower screens partially overlap after folding). If the upper and middle screens are foldable, and the middle and lower screens are also foldable, and the upper, lower, and middle screens completely overlap after folding, then the entirety of the upper, middle, and lower screens will be used as the preset area. In practical applications, preset areas can also be set according to the specific structure of the screen in the electronic device or the specific overlapping area after the screen is folded. This application embodiment does not make specific limitations.

After determining the screen pressure location in step S10, it can be determined whether the screen pressure location is within a preset area. If the screen pressure location is within the preset area, it means that the user's finger may have pressed on an easily damaged area of the screen, and the risk of screen damage is relatively high. In other words, there is an abnormal operation at this time, and an abnormal operation reminder can be issued. If the screen pressure location is not within the preset area, it means that although the screen is under pressure, it may be a normal touch screen operation, and the user's finger has not pressed on an easily damaged area of the screen. The risk of screen damage is relatively low, and there is no abnormal operation at this time. No abnormal operation reminder is needed. At this time, it can return to step S10 to continue pressure detection and abnormal operation judgment, so as to realize that once the screen pressure location is found to be within the preset area, an abnormal operation reminder can be issued immediately.

In addition, abnormal operation alerts refer to electronic devices notifying users of any abnormal behavior during the switching of the device's physical form. There are various ways to issue abnormal operation alerts, such as using the device's processor to activate a motor for vibration, using a speaker for voice alerts, or displaying a pop-up window on the screen. These methods are not limited here. Abnormal operation alerts can be output directly or indirectly by the electronic device, such as sending alert commands via Bluetooth to the user's wristband, watch, or headphones, causing them to respond accordingly, including through vibration, voice, or pop-up windows. The methods for outputting abnormal operation alerts are not limited to these; they can be configured as needed in practical applications.

This embodiment provides an abnormal operation alert method. By determining the pressure point on the screen during the physical transformation of the electronic device's screen, and then outputting an abnormal operation alert when the pressure point is within a preset area, the method can continuously identify abnormal operation behaviors during the folding or unfolding of the electronic device's screen. Once an abnormal operation is detected, an alert is issued so that the user is promptly aware of the risk of screen damage and can stop the risky operation. By setting a preset area, the method accurately identifies pressure operations in areas of the screen that are more easily damaged by pressure, avoiding finger pressure on the screen during folding, thereby reducing the risk of damage to the foldable screen and extending its lifespan.

Based on the first embodiment of the abnormal operation reminder method of this application, in the second embodiment of the abnormal operation reminder method of this application, the same or similar content as the above embodiment can be referred to the above description, and will not be repeated hereafter. On this basis, referring to Figure 5, which is a flowchart of the second embodiment of the abnormal operation reminder method provided by this application, step S20 includes steps S211 to S212:

Step S211: When the screen pressure position is within a preset area, detect the screen pressure at the screen pressure position.

Screen pressure refers to the pressure exerted on the screen at the contact point between a finger or foreign object and the screen. Screen pressure can be detected using pressure sensors or pressure sensing matrices located beneath the screen.

As exemplified by Figure 6, which is a schematic diagram of the screen structure of an electronic device, the screen 110 may include a touchscreen 113, a display screen 114, and a pressure screen 115 stacked from top to bottom. The touchscreen 113 can recognize finger touch actions and obtain the coordinate data of the finger to determine the pressure position on the screen. The pressure screen 115 can detect the touch pressure corresponding to the finger touch action to obtain the screen pressure. For example, when a finger touches the screen, the touchscreen 113 recognizes the finger touch action and provides corresponding coordinate data. Based on this coordinate data, it determines the specific position where the finger contacts the screen, obtaining the screen pressure position. When the screen pressure position is within a preset area, the pressure screen 115 collects the pressure applied by the finger to obtain the screen pressure at the pressure position.

Step S212: If the pressure applied to the screen meets the abnormal pressure condition, output an abnormal operation reminder.

An abnormal pressure condition refers to a preset pressure threshold value that may cause screen damage due to excessive pressure, or a preset pressure threshold range that may cause screen damage when pressure exceeding a certain range is applied to the screen. Meeting an abnormal pressure condition means that the pressure applied to the screen is less than the preset pressure threshold value, or that the pressure applied to the screen is within the preset pressure threshold range. The specific choice can be made according to actual needs and is not limited here.

The preset area can include multiple parts, and the pressure abnormality conditions of each part can be set accordingly. When the screen is under pressure in a certain part of the preset area, the screen pressure at the pressure location is detected, and the pressure magnitude is compared based on the corresponding pressure abnormality conditions of that part. This allows for targeted alerts for abnormal operations in different areas or at different levels.

When the screen pressure position obtained in step S10 is within the preset area, the electronic device detects the screen pressure and determines whether the screen pressure meets the abnormal pressure conditions. For example, it determines whether the screen pressure exceeds the set threshold. If so, it means that the user has not only pressed a vulnerable area on the screen, but also pressed a large amount of pressure, resulting in a very high risk of screen damage. In other words, there is an abnormal operation, and an abnormal operation reminder can be issued. Specifically, the electronic device outputs the abnormal operation reminder. If not, no action is required and no reminder is needed. At this time, the process can return to step S10 to continue detecting the pressure position, pressure magnitude, and abnormal operation.

This embodiment provides an abnormal operation reminder method, which differs from the first embodiment in that it judges abnormal operation only by the pressure position of the screen. Specifically, it judges abnormal operation by combining the pressure position of the screen and the pressure applied to the screen. It identifies obvious abnormal operations that are pressed into a preset area that is easily damaged and the pressure is too high, and promptly reminds users of the abnormal operation so that they can stop the abnormal operation as soon as possible and avoid damaging the screen of the electronic device.

Based on the first embodiment of the abnormal operation reminder method of this application, in the third embodiment of the abnormal operation reminder method of this application, the same or similar content as the above embodiment can be referred to the above description, and will not be repeated hereafter. On this basis, step S20 may include two feasible implementation methods.

In one feasible implementation, the physical form switching process includes switching to a folded state.

Figure 7 illustrates the operation of switching the screen to a folded state. Taking a foldable phone screen consisting of two halves (top and bottom) as an example, many users habitually fold the screen with one hand, as shown in Figure 7. This requires the thumb to press down on the bottom half of the screen, while the index and middle fingers push from the back of the top half to fold the entire device. Folding the screen is a physical change in screen form. When switching from an unfolded to a folded state, folding the screen with one hand requires pressing down on the bottom half with considerable force, which can easily damage the screen, resulting in bright spots or black spots. Therefore, it is necessary to identify this abnormal one-handed screen folding operation and provide corresponding alerts.

In Figure 7, the position where the thumb presses the screen 110 is the screen pressure position, and the contact point between the finger and the screen corresponding to the screen pressure position is a pressure point 150.

Based on this, referring to Figure 8, which is a flowchart of a third embodiment of the abnormal operation alert method provided in this application, step S10 includes step S101:

Step S101: During the process of switching the screen of the electronic device to a folded state, determine the pressure position of the screen.

Correspondingly, step S20 includes steps S221 to S222:

Step S221: Determine the number of pressure points on the screen based on the pressure location of the screen.

Step S222: When there is only one pressure point and the pressure point on the screen is within a preset area, output an abnormal operation reminder.

The pressure point refers to the contact point at the corresponding position when a finger or foreign object comes into contact with the screen. As shown in Figure 7, when a folding operation is performed with one hand, there is one pressure point 150 corresponding to the pressure position of the screen.

Once the electronic device determines the pressure point on the screen, and confirms that there is only one pressure point, and also recognizes that the pressure point is within a preset area, it indicates that the user is folding the screen with one hand. This operation is a risky operation that could easily damage the screen, and an abnormal operation alert is required. That is, when the electronic device determines that there is only one pressure point and the pressure point is within the preset area, it outputs an abnormal operation alert.

For example, referring to Figures 6 and 7, when a finger touches the screen, the touch screen 113 of the screen 110 can provide reporting point coordinate data. The electronic device confirms that a finger is touching the screen 110 based on the reporting point coordinate data, and determines the specific position based on the reporting point coordinate data to obtain the screen pressure position. Then, it also determines the number of pressure points 150 on the screen 110 according to the number of screen pressure positions. If the number of pressure points 150 is one, and the screen pressure position is located within a preset area, it is determined that there is an abnormal operation, and the electronic device provides an abnormal operation reminder.

In this embodiment, by determining the number of pressure points on the screen and combining the pressure location on the screen, the single-hand folding operation is specifically identified. During the screen folding operation, representative and typical risky operations that are prone to screen damage are accurately identified, and corresponding accurate abnormal operation reminders are given.

In another feasible implementation, the physical form switching process includes switching to the unfolded state.

Figure 9 illustrates the operation of switching the screen to the unfolded state. Taking a foldable phone screen, consisting of two halves (top and bottom), as an example, many users habitually operate the unfolding operation with one hand. As shown in Figure 9, the thumb needs to be inserted between the overlapping folded screen halves, pressing down on the bottom half and then pushing up the top half to unfold the entire device. Unfolding the screen is a physical change in screen form. If the screen is unfolded with one hand during this process, the thumb needs to push up the top half with considerable force, which can easily damage the screen, causing bright spots or black spots. Therefore, it is necessary to identify this abnormal one-handed screen unfolding operation and provide corresponding alerts.

In Figure 9, the position where the thumb presses the screen 110 is the screen pressure position. When the thumb presses between the folded screens, there are two screen pressure positions. There are two pressure points on the screen 110, namely the first pressure point 151 and the second pressure point 152, as shown in Figure 9. The first pressure point 151 is the position where the finger presses the screen, and the second pressure point 152 is the position where the finger presses against the screen. When the screen 110 is folded, the positions of the first pressure point 151 and the second pressure point 152 are symmetrical.

Based on this, referring to Figure 10, which is another flowchart of the third embodiment of the abnormal operation reminder method provided in this application, step S10 includes step S102:

Step S102: During the process of switching the screen of the electronic device to the unfolded state, determine the pressure position of the screen.

Correspondingly, step S20 includes steps S231 to S232:

Step S231: Determine the number of pressure points on the screen based on the pressure location on the screen.

Step S232: When there are two pressure points and the two pressure points are symmetrically positioned, and the pressure point on the screen is within a preset area, output an abnormal operation reminder.

As shown in Figure 9, when the screen is unfolded with one hand, there are two pressure points corresponding to the pressure position, namely the first pressure point 151 and the second pressure point 152. Furthermore, the positions of the first pressure point 151 and the second pressure point 152 are symmetrical.

Once the electronic device determines the pressure points on the screen, and confirms that there are two pressure points that are symmetrical, and if it also detects that both pressure points are within a preset area, it indicates that the user is unfolding the screen with one hand. This operation is considered a risky operation that could easily damage the screen, and an abnormal operation alert is required. In other words, the electronic device outputs an abnormal operation alert when it confirms that there are two pressure points that are symmetrical and that the pressure points are within a preset area.

For example, referring to Figures 6 and 9, when a finger is squeezed between the folded screens 110, the touch screen 113 of the screen 110 can provide two sets of reporting coordinate data. The electronic device confirms that a finger is touching the screen 110 based on the reporting coordinate data, and determines the specific position based on the reporting coordinate data to obtain two screen pressure positions. Then, it also determines the number of pressure points on the screen 110 according to the number of screen pressure positions. If the number of pressure points is two, and the two pressure points are determined to be symmetrical based on the screen pressure positions, and both screen pressure positions are located within a preset area, it can be determined that there is an abnormal operation, and the electronic device will issue an abnormal operation reminder.

In this embodiment, by determining the number of pressure points on the screen and combining the pressure location on the screen, the operation of unfolding the screen with one hand is specifically identified. During the operation of unfolding the screen, representative and typical risky operations that are prone to screen damage are accurately identified, and corresponding accurate abnormal operation reminders are given.

The difference between the first and second embodiments described above lies in the different physical form switching processes, which results in different identification methods for subsequent one-handed operations, specifically one-handed folding or one-handed unfolding. The first embodiment identifies abnormal operations of one-handed folding, while the second embodiment identifies abnormal operations of one-handed unfolding. Compared to the aforementioned embodiments, both embodiments can improve the accuracy of abnormal operation identification, thereby improving the accuracy of abnormal operation alerts.

The above are merely two feasible implementations of step S20 in the third embodiment of the abnormal operation reminder method provided in this application. Optionally, the screen pressure at the pressure-bearing position can be further detected, and an abnormal operation reminder can be output only when the screen pressure meets the abnormal pressure condition, so as to further improve accuracy. This application does not specifically limit the specific implementation of step S20.

Based on the first embodiment of the abnormal operation reminder method of this application, in the fourth embodiment of the abnormal operation reminder method of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. On this basis, the screen of the electronic device includes at least two split screens. The following description uses an example including two split screens.

Figure 11 shows a schematic diagram of the screen splitting of an electronic device. Screen 110 includes a first split screen 111 and a second split screen 112. When screen 110 is folded, the first split screen 111 and the second split screen 112 overlap. Figure 12 shows a schematic diagram of the display screen partitioning in Figure 11. Referring to Figure 7, screen 110 includes a touchscreen 113, a display screen 114, and a pressure-sensitive screen 115. The central area of display screen 114 is a fully etched area 131, and the areas on either side of the fully etched area 131 are semi-etched areas 132. When the screen is bent, the bending area corresponding to the fully etched area 131 is teardrop-shaped and has relatively low bending stress. The semi-etched areas 132 reduce the stress in the bending area. Therefore, in the screen area corresponding to the fully etched area 131, if the pressure is too high, the screen deformation in that area will be significant, leading to damage such as bright spots or black spots on display screen 114. Therefore, the screen areas corresponding to the fully etched area 131 and/or the semi-etched area 132 in display screen 114 are more prone to damage and are considered high-risk areas.

Based on this, an exemplary example is shown in Figure 13, which is an example of the preset area of the screen in Figure 11. The preset area in the screen 110 corresponds to the fully etched area 131, or to the area within a preset range of the fully etched area 131 and its vicinity. That is to say, the preset area can be the boundary area of two adjacent split screens or the preset range area on both sides of the boundary area. For example, the preset area here is the first area 130, specifically the boundary area between the first split screen 111 and the second split screen 112, as well as the lower fifth of the first split screen 111 and the upper fifth of the second split screen 112. In actual applications, the area size can be adjusted accordingly. This is only an example and is not specifically limited.

For high-risk areas on the screen of electronic devices, preset areas can be set accordingly. This allows for a more accurate comparison between the pressure points on the screen and the preset areas, enabling the accurate identification of high-risk abnormal operations and the output of abnormal operation alerts.

In a feasible implementation, referring to FIG14, FIG14 is a flowchart of a fourth embodiment of the abnormal operation reminder method provided in this application, wherein step S10 includes steps S11 to S13:

Step S11: Determine the included angle between two adjacent split screens.

Step S12: When the screen is determined to be in the process of physical form switching based on the included angle, obtain the touch screen coordinate data.

Step S13: Determine the pressure position on the screen based on the touch screen coordinate data.

The angle between two adjacent split screens can be determined by the acceleration of electronic devices in different directions. This angle can then be used to identify the state between the two split screens; for example, when the angle is 0 degrees, the two split screens are folded and overlap; when the angle is 180 degrees, the two split screens unfold and form a complete screen. The specific physical form switching process of the screen can also be identified based on changes in the angle. Touchscreen coordinate data refers to the coordinate data of the contact point between a finger or foreign object and the screen. Touchscreen coordinate data can be obtained using the screen's display or pressure-sensitive screen, or using a three-axis accelerometer or three-axis gyroscope located under the screen.

For example, as shown in Figure 11, a first sensor 141 can be disposed below the first split screen 111 within the housing 120 of the electronic device 100, and a second sensor 142 can be disposed below the second split screen 112 within the housing 120. Both the first sensor 141 and the second sensor 142 are three-axis accelerometers or three-axis gyroscopes. In practical applications, the first sensor 141 can be disposed on the main board of the first split screen 111, and the second sensor 142 can be disposed on the main board of the second split screen 112. The angle between the first split screen 111 and the second split screen 112 can be detected by the first sensor 141 and the second sensor 142. By observing the change in the angle, it can be identified whether the screen 110 is currently switching to a folded state or a unfolded state, thus recognizing the physical form switching process. In practical applications, data from the two sensors can be collected in real time to calculate the angle between the two split screens in real time, determining the real-time state of the screen and the specific physical form switching process.

In one possible implementation, step S12 includes step S121:

Step S121: If the screen is determined to be in the initial stage of the physical form switching process based on the included angle, obtain the touch screen coordinate data.

Regardless of whether the screen is in the process of switching to a folded state or a unfolded state, as long as the change in the angle is used to identify the physical form switching process, the touch screen coordinate data can be obtained at the beginning of the process and will continue to be obtained until the screen is in a folded state after the folding operation is completed or in an unfolded state after the unfolding operation is completed.

For example, when the acquired angle decreases from a large value (e.g., from 150° to 120°), the decrease in angle reaches a specified value (e.g., a reduction of 30°), or the angle decreases from one fixed value to another (e.g., from 180° to 150°), the current physical form switching process can be determined as a switch to the folded state. Specific settings can be selected as needed and are not limited here. Correspondingly, the starting stage of the switch to the folded state refers to the initial stage when the screen begins to fold from the fully unfolded state, such as when the angle decreases from 180° to 150°, at which point touch screen coordinate data is acquired.

For example, when the acquired angle increases from a small value (e.g., from 30° to 60°), the angle increases by a specified range (e.g., by 30°), or the angle increases from one fixed value to another (e.g., from 0° to 30°), the current physical form switching process can be determined as a switch to the unfolded state. Specific settings can be selected as needed and are not limited here. Correspondingly, the starting stage of the switch to the unfolded state refers to the initial stage when the screen begins to unfold from a fully folded state, such as when the angle increases from 0° to 30°, at which point touchscreen coordinate data is acquired.

In this embodiment, the specific physical form switching process of the screen is determined by the angle between the folding screens. The timing for obtaining touch screen coordinate data or the subsequent abnormal operation recognition method can be selected according to the specific physical form switching process.

In some feasible embodiments, the screen of the electronic device also includes a camera, which is located on either of two adjacent split screens, and the physical form switching process includes switching to a folded state.

For example, as shown in Figure 15, which is a schematic diagram of the camera position of an electronic device, the screen 110 also includes a camera 160, which is set on the first split screen 111, specifically a front-facing camera. The shooting area of the camera 160 is shown by the dotted line in Figure 15, and it shoots the space between the first split screen 111 and the second split screen 112. It can be understood that the shooting area can also be adjusted according to actual needs.

Referring to Figure 16, which is another flowchart of the fourth embodiment of the abnormal operation reminder method provided in this application, step S20 includes steps S241 to S243:

Step S241: If the screen is determined to be in a physical form switching process based on the included angle, the camera is activated.

Step S242: Based on the images captured by the camera, perform foreign object detection on the space between two adjacent split screens to obtain the foreign object detection result.

Step S243: If the foreign object detection result indicates the presence of a foreign object and/or the screen pressure position is located within a preset area, an abnormal operation alert is output.

Foreign object detection can be achieved using image recognition technology, deep learning classification algorithms, machine learning models, etc. Specifically, it involves detecting images captured by the camera to identify foreign objects that may damage the screen. There are various methods for foreign object detection, which are not limited here.

Figure 17 illustrates an example of a foreign object present in the space between the two split screens in Figure 15. When a foreign object 200 exists between the first split screen 111 and the second split screen 112, the object 200 will be trapped when the two split screens are folded. Since the screen itself is flexible, the foreign object 200 can easily squeeze the screen, potentially causing damage such as bright spots or black spots. Therefore, in addition to the possibility of screen damage from finger pressure, if a foreign object exists in the folding space (between the two split screens), even if the potential damage from finger pressure is overcome, screen damage may still occur after folding. Therefore, a foreign object detection function could be further provided.

For example, after step S11, when the screen is in the process of switching to the folded state based on the included angle, the electronic device activates the camera, performs foreign object detection based on the image captured by the camera, obtains the foreign object detection result, and then, based on the screen pressure position in step S13 and the foreign object detection result in step S242, if the foreign object detection result indicates the presence of a foreign object, or if the screen pressure position is within a preset area, an abnormal operation reminder is output. Optionally, when the foreign object detection result indicates the presence of a foreign object and the screen pressure position is within the preset area, an abnormal operation reminder is output. The specific settings can be selected according to actual needs.

In this embodiment, not only can abnormal operations such as finger pressing on the screen be identified and alerted, but also situations where foreign objects may compress the screen when the screen is folded can be identified and alerted, thus enabling the identification and alerting of more abnormal situations that may damage the screen, making the function more comprehensive.

In one possible implementation, step S241 includes step S2411:

Step S2411: When it is determined that the screen is in the process of physical form switching, the camera is activated and the other split screen in the two adjacent split screens that does not have a camera set up is controlled to display a preset image.

The preset image can be a solid color image, such as a pure white image, or it can be another pre-stored image that is easy to identify if there are foreign objects on the screen surface corresponding to the other split screen. There are no restrictions here.

For example, as shown in Figure 15, the other split screen that does not have a camera is the second split screen 112. When the electronic device is switching to the folded state, it can simultaneously control the second split screen 112 to display a preset image while activating the camera 160.

In this embodiment, while the camera is capturing images, another split screen is controlled to display a preset image. This makes the detection results more accurate when performing foreign object detection based on the images captured by the camera, thereby improving the accuracy of abnormal operation alerts.

The abnormal operation reminder method provided in this application relies on program improvement to identify and remind users of potential risks to the screen. Without increasing costs, it can identify abnormal operations and eliminate risks, prevent the screen from being damaged by pressure, extend the folding life of the display screen and reduce damage from bending the screen, thereby meeting the usage needs of more users and improving the usability of the product and the user experience.

The above examples are only used to understand the embodiments of this application and do not constitute a limitation on the abnormal operation reminder method of the embodiments of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

Step s20: Based on the images captured by the camera, perform foreign object detection on the space between two adjacent split screens to obtain the foreign object detection results.

Step s30: If the foreign object detection result indicates the presence of a foreign object, output an abnormality alert.

In some feasible embodiments, step s10 includes step s110:

Step s110: During the physical form switching process of the electronic device screen, the camera is activated and the preset image is displayed on the other of the two adjacent split screens that does not have a camera.

In some feasible embodiments, step s10 includes steps s121 to s122:

Step s121: Determine the included angle between two adjacent split screens.

Step s122: If the screen is determined to be in a physical form switching process based on the included angle, the camera is activated.

In some feasible embodiments, step s30 includes steps s310 to s320:

Step s310: If the screen is in the process of physical form switching based on the included angle, determine the pressure position of the screen.

Step s320: If the foreign object detection result indicates the presence of a foreign object and/or the screen pressure location is within a preset area, an abnormality alert is output.

Referring to FIG19, FIG19 provides a schematic diagram of the module structure of an abnormal operation reminder device. The abnormal operation reminder device is applied to an electronic device with a foldable screen.

One example is that the preset area is the overlapping area of at least two screens in a folded state.

In one example, the reminder module M20 is further configured to detect the screen pressure at the screen pressure location when the screen pressure location is within a preset area; and to output an abnormal operation reminder when the screen pressure meets the abnormal pressure condition.

In one optional example, the physical form switching process includes switching to a folded state; the reminder module M20 is also configured to determine the number of pressure points on the screen based on the pressure position of the screen; and output an abnormal operation reminder when the number of pressure points is one and the pressure position of the screen is within a preset area.

In one optional example, the physical form switching process includes switching to the unfolded state; the reminder module M20 is also configured to determine the number of pressure points on the screen based on the screen pressure position; and output an abnormal operation reminder when there are two pressure points and the two pressure points are symmetrically positioned, and the screen pressure position is located within a preset area.

In one example, the screen includes at least two sub-screens; the detection module M10 is also configured to determine the angle between two adjacent sub-screens; when it is determined that the screen is in a physical form switching process based on the angle, it acquires touch screen coordinate data; and determines the pressure position of the screen based on the touch screen coordinate data.

In one example, the detection module M10 is also configured to acquire touch screen coordinate data when the screen is determined to be in the initial stage of a physical form switching process based on the included angle.

In one example, the screen of the electronic device also includes a camera, which is located on either of two adjacent split screens. The physical form switching process includes switching to a folded state. The reminder module M20 is also configured to activate the camera when the screen is determined to be in a physical form switching process based on the included angle. The camera is used to detect foreign objects in the space between the two adjacent split screens based on the image captured by the camera, and a foreign object detection result is obtained. If the foreign object detection result indicates the presence of a foreign object and/or the screen pressure position is located within a preset area, an abnormal operation reminder is output.
