Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Figure 1, the multimedia data playback control method of the embodiment of the present invention is applied to a mobile terminal provided with a flexible screen, and the method includes:

Step 101, if an instruction to play multimedia data is received, then detect bending parameters of the flexible screen.

In this step, the user's demand for playing multimedia data is known through the received instruction to play multimedia data, and then the bending parameter detection of the flexible screen is performed. Wherein, the user will input an instruction to play multimedia data based on a preset trigger mode. There can be various ways of triggering, such as being triggered by a physical button or a virtual button, or by biometric technology, etc., which will not be listed here.

Step 102, based on the detected bending parameters, determine a first display ratio of the flexible screen.

In this step, based on the bending parameters detected in step 101, the first display ratio of the flexible screen is determined for subsequent playback.

Step 103, determining the first display ratio as the playback ratio of the multimedia data.

In this step, the first display ratio determined in step 102 is determined as the playback ratio of the multimedia data, so as to facilitate the adaptive playback of the flexible screen and the multimedia data afterwards.

Step 104: Play the multimedia data according to the playing ratio.

In this step, after step 103, the multimedia data can be played according to the playback ratio, so as to realize the adaptive playback of the flexible screen and the multimedia data.

In the multimedia data playback control method of the embodiment of the present invention, after receiving an instruction to play multimedia data, the first display ratio of the flexible screen is determined based on the bending parameters by detecting the bending parameters of the flexible screen, and then the first The display ratio is determined as the playback ratio of the multimedia data, and finally, the multimedia data is played according to the playback ratio. In this way, after the adaptation and adjustment of the flexible screen and multimedia data, the playback of multimedia data can avoid the problem of affecting the playback effect due to the incompatibility of the two, and improve the playback effect of multimedia data and the applicability of the mobile terminal.

Preferably, in order to complete the corresponding adjustment of the playback, the first display ratio and the playback ratio in this embodiment both refer to the aspect ratio.

Wherein, the multimedia data to be played is not limited to individual video and audio files, and may also be user interface images of application programs, etc., which will not be listed here.

It should be known that the triggering of the above-mentioned instruction to play multimedia data can also be realized by a menu setting option of the multimedia data to be played. Taking a game program as an example, you can choose to enable the adaptive function of the flexible screen in its setting menu, trigger an instruction to play multimedia data, and execute the above steps 101-104. By detecting the bending parameters of the current flexible screen, first based on the The bending parameters are used to determine the first display ratio of the flexible screen, and then the first display ratio is determined as the playback ratio of the user interface image of the game program, so that the user interface image is played according to the playback ratio. In this way, the user interface image can avoid problems of being stretched, cropped, or black borders on the screen due to incompatibility with the display area, thereby achieving a better playback effect.

Of course, it is also possible to choose not to enable the adaptive function of the flexible screen in the menu setting, so as to play the multimedia data in a default manner. In addition, the trigger mode of the menu setting option can also add a memory function. When the user enters the same application program next time, there is no need to select again, and the corresponding mode will continue to be played last time, making the use of the mobile terminal more convenient. It is convenient and reduces the frequent operations of users.

In the embodiment of the present invention, since the mobile terminal is equipped with a flexible screen, the user can manually bend the flexible screen at any point in the width and height direction according to his own preferences and needs, as shown in Figure 2 and Figure 3, the second The first area 201 and the second area 202 are bent to the other side, and the unbent third area 203 will be used as a display area for playing multimedia data. Therefore, on the basis of the above embodiments, in step 101, the step of detecting the bending parameters of the flexible screen includes:

Detect the user's bending control operation on the flexible screen;

If the user's bending control operation on the flexible screen is detected, the bending parameters of the flexible screen are acquired.

Here, by detecting the user's bending control operation on the flexible screen, the bending parameters of the flexible screen, such as the bending area, bending direction and bending angle, etc., will be obtained, and the user's bending of the flexible screen will be known, so that Subsequently, according to the bending of the flexible screen, the multimedia data is adjusted to fit the user's desired display area for playing.

Among them, the bent area on the other side of the flexible screen can also be used to support the unbent area, improving the free movement of the user's hands.

For example, with regard to the flexible screen shown in FIG. 2 and FIG. 3 , after the user performs bending control operation on the flexible screen, the mobile terminal can stand on the desktop with the support of its own first area 201 and second area 202 . The bending control operation is detected, and bending parameters (such as bending area, bending direction, etc.) are obtained by determining the bending position of the flexible screen.

Specifically, as shown in Figure 4, step 102 includes:

Step 1021, extract the bending area in the bending parameters.

In the above method, when the user actively performs a bending control operation on the flexible screen, the bending parameters of the flexible screen will be obtained. In this step, the required bending area can be directly extracted from the bending parameters.

Step 1022: Determine the unbent area of the flexible screen according to the bending area.

In this step, after the bending area is extracted in step 1021, the unbending area of the flexible screen can be determined in combination with the overall area of the flexible screen when it is not bent.

Step 1023, acquire the display ratio of the unbent area.

In this step, after the unbent area is determined in step 1022, the display ratio of the current unbent area can be acquired. Taking the third area 203 of the unbent area in FIG. 3 as an example, when the display ratio cannot be obtained directly, the corresponding display ratio c:d can be calculated based on the current display resolution a*b of the third area 203 .

Step 1024, determining the display ratio of the unbent region as a first display ratio.

In this step, the display ratio of the unbent area acquired in step 1023 above will be determined as the first display ratio of the flexible screen.

In this way, through step 1021-step 1024, by extracting the bending area in the bending parameters of the flexible screen after the user's bending control operation, the unbent area in the flexible screen can be determined, and then the unbent area can be obtained. The display ratio of the region is determined as the first display ratio. Like this, when as step 103 and step 104, the first display ratio is used as the playback ratio of the multimedia data, and when playing the multimedia data with the first display ratio, due to The playback ratio of multimedia data is equal to the display ratio of the current unbent area of the flexible screen, which can effectively avoid the problems of being stretched, cut or black borders on the screen due to incompatibility with the display area, and achieve better playback effects.

Among them, considering that the original playback ratio of the multimedia data is determined when the multimedia data is produced, after determining the display ratio of the unbent area of the flexible screen, the display ratio of the unbent area is often different from the display ratio of the multimedia data. The original playback ratio is different. At this time, the display ratio of the unbent area is used as the playback ratio of the multimedia data to scale the multimedia data. Still taking the flexible screen shown in Figure 3 as an example, the scaling ratio in the width direction of the multimedia data and the scaling ratio in the height square are determined by the original playback ratio of the multimedia data to be played and the display ratio of the third area 203, and then the The multimedia data is processed so that its playback ratio is consistent with the display ratio of the unbent area. Moreover, due to the corresponding relationship between the aspect ratio and the display resolution, the original display resolution n*m of the multimedia data to be played and the display resolution p*q of the third area 203 can be used to obtain the scaling ratio p in the width direction of the multimedia data /n and the highly square zoom ratio q/m, and then process the multimedia data so that the playback ratio is consistent with the display ratio of the unbent area.

Of course, in practical applications, the user may not actively bend the flexible screen. In this case, before the step of detecting the bending parameters of the flexible screen in step 101, the steps include:

Get the initial display ratio of the flexible screen;

Acquiring a second display ratio of the multimedia data;

comparing the second display scale with the initial display scale;

If the second display ratio is different from the initial display ratio, control the flexible screen to bend according to the initial display ratio and the second display ratio.

Here, for the case where the flexible screen is not actively bent by the user, the initial display ratio of the flexible screen (that is, the display ratio in the unbent state of the flexible screen) and the second display ratio of the multimedia data (that is, the display ratio of the multimedia data) will be obtained first. Original display ratio), by comparing the second display ratio with the initial display ratio, if the two are different, the initial display ratio and the second display ratio are used to control the bending of the flexible screen. In this way, after the flexible screen is bent, the display ratio of the unbent area of the flexible screen can be the same as the second display ratio, so that when the multimedia data is played in the unbent area of the flexible screen, when the user clicks to play or After triggering and starting, you can start playing movies, games or other multimedia data. Before playing, the flexible screen can automatically adjust itself according to the size of the multimedia data. After the multimedia is played, the multimedia screen can maintain its own display ratio for playback without deformation and distortion of the screen. At the same time, the screen is displayed in full screen without black borders, which improves the multimedia experience.

Specifically, in the above steps, the step of controlling the bending of the flexible screen according to the initial display ratio and the second display ratio includes:

Determine the bending area of the flexible screen according to the initial display ratio and the second display ratio;

Obtain the preset bending direction and bending angle;

controlling the bending area of the flexible screen to bend according to the preset bending direction and bending angle;

Wherein, the display ratio of the bent flexible screen is the first display ratio, and the first display ratio is the same as the second display ratio.

Here, according to the obtained initial display ratio and second display ratio, the bending area of the flexible screen is determined when the two are the same, and then the bending direction and bending angle preset in the mobile terminal are obtained. Control the bending area of the flexible screen to be bent according to the preset bending direction and bending angle, so as to achieve the purpose that the display ratio of the unbent area of the flexible screen after bending is the same as the second display ratio, and also That is, the first display ratio is the same as the second display ratio. Afterwards, the multimedia data can be played optimally in the unbent area of the flexible screen without problems such as stretching, clipping, or black borders on the screen.

Further specifically, according to the initial display ratio and the second display ratio, the step of determining the bending area of the flexible screen includes:

If the initial display ratio is greater than the second display ratio, calculate the adjusted pixel value in the width direction of the flexible screen;

The bending area of the flexible screen is determined based on the adjusted pixel value in the width direction.

Here, by knowing that the initial display ratio is greater than the second display ratio, preferably, it will be determined that the flexible screen is bent in the width direction, so the adjusted pixel value in the width direction of the flexible screen will be calculated, and based on the adjusted pixel value in the width direction, Determine the bending area of the flexible screen. In this way, the required bending area can be determined for the situation that the display pixels in the width direction of the flexible screen are more than the actual playback requirements, so as to ensure the effect of subsequent playback.

For example, the current flexible screen of a mobile terminal is shown in Figure 5, and its initial display ratio is greater than the second display ratio of the multimedia data to be played. According to the above method, the width direction of the flexible screen can be calculated from the second display ratio of 16:9. The adjusted pixel value Y1, Y1=X1/9*16, where X1 is the display pixel value in the height direction of the flexible screen, at this time, according to the pixel arrangement information inside the flexible screen, find the positioning point A, and determine the bending area 501 . In this way, as shown in Figure 12, after the mobile terminal controls the bending of the bending area 501, the display ratio of the unbent area 502 on the flexible screen will be the same as the second display ratio of the multimedia data. , it can ensure the best proportion of the multimedia screen to play in full screen, and the screen is not distorted and has no black borders.

In addition, according to the initial display ratio and the second display ratio, the step of determining the bending area of the flexible screen includes:

If the initial display ratio is smaller than the second display ratio, calculate the adjusted pixel value in the height direction of the flexible screen;

A bending area of the flexible screen is determined based on the adjusted pixel value in the height direction.

Here, by knowing that the initial display ratio is smaller than the second display ratio, preferably, it will be determined that the flexible screen is bent in the height direction, so the adjusted pixel value in the height direction of the flexible screen will be calculated, and based on the adjusted pixel value in the height direction, Determine the bending area of the flexible screen. In this way, the required bending area can be determined for the case where the display pixels in the height direction of the flexible screen are more than the actual playback requirements, so as to ensure the effect of subsequent playback.

For example, the current flexible screen of a mobile terminal is shown in Figure 6, and its initial display ratio is smaller than the second display ratio of the multimedia data to be played. According to the above method, the height direction of the flexible screen can be calculated from the second display ratio of 21:9. The adjusted pixel value Y2, Y2=X2/21*16, where X2 is the display pixel value in the width direction of the flexible screen, at this time, according to the pixel arrangement information inside the flexible screen, find the positioning point B, and determine the bending area 601 . In this way, as shown in Figure 13, after the mobile terminal controls the bending of the bending area 601, the display ratio of the unbent area 602 on the flexible screen will be the same as the second display ratio of the multimedia data. , it can ensure the best proportion of the multimedia screen to play in full screen, and the screen is not distorted and has no black borders.

It should also be known that, in the above-mentioned embodiments of the present invention, since the multimedia data is finally played in the unbent area after the flexible screen is bent, after step 102, it also includes:

Control the pixels of the bending area to turn off.

Since the bending area is not used for playing multimedia data, after determining the first display ratio of the flexible screen, the pixels corresponding to the bending area can be turned off to avoid unnecessary power consumption and extend the standby time.

Of course, after the playback of the multimedia data is completed, the mobile terminal needs to control the flexible screen to restore the unbent state, and control the activation of the closed pixels, so that the mobile terminal can perform other applications later.

To sum up, the multimedia data playback control method of the embodiment of the present invention, after receiving an instruction to play multimedia data, detects the bending parameters of the flexible screen, and determines the first display ratio of the flexible screen based on the bending parameters. , determining the first display ratio as the playback ratio of the multimedia data, and playing the multimedia data according to the playback ratio. In this way, after the adaptation and adjustment of the flexible screen and multimedia data, the playback of multimedia data will maintain the best ratio, and the picture will not be deformed and distorted. playback effect, and the applicability of mobile terminals.
