Description
Technical Field

Background
Burning screen: for devices using OLED screens, a shadow-like background will always remain after one image (e.g., navigation buttons on a cell phone, scoreboard, etc.) is displayed for a long time at the same location on the display, no matter what other images are displayed on the display. For this phenomenon we call burn-in. Burn-in damage is permanent and irreversible. So the burn-in is a problem that is not easily emphasized in the early stage, but is relatively serious after occurrence and has no possibility of repairing.
Because the use of OLED screens has not been popular on all devices and the generation of burn-in requires special scenes and heavy use, most of the average users do not risk burn-in. This problem is not widely appreciated.
At present, only part of mobile phone manufacturers do screen burn prevention aiming at system-level image elements, such as status bars, navigation bars and virtual buttons, and the main scheme is to do fine pixel-level movement on the image elements at regular time so as to slow down screen burn. But application software is used with a larger screen scale. The application software cannot generally perform screen burn protection, and the screen burn phenomenon is likely to be caused due to long-time use of the application software.

Referring to fig. 1, fig. 1 is a flowchart of a burn-in screen protection method according to an embodiment of the present disclosure.
S110, determining a time interval of screen burn-in detection for a terminal screen.
The screen burn detection is to detect the change condition of the color value displayed by the same pixel point in a certain period of time. That is, for the same pixel point, at least two times of screen burn-in detection are performed, and corresponding color values are obtained. And determining the corresponding screen burn risk according to the color values detected by the screen burn twice. The time interval between the two screen burn-in detection is the time interval of the screen burn-in detection.
Therefore, in the process of screen burn-in detection, the time interval of screen burn-in detection for the screen needs to be determined according to the use condition of the terminal screen.
And before this step, further comprising:
when the application program is detected to be started, the corresponding starting time of screen burn detection is determined according to the current use state of the terminal central processing unit.
The starting time of the screen burn detection is the running condition of the combined application program, the running condition can comprise the changing condition of the color value of the pixel point of the application program and the running condition of the application program, and even the running condition of the current terminal can be combined to determine the starting time of the screen burn detection.
When a user sends an enabling instruction to the terminal for the application program, the terminal responds to the enabling instruction to trigger the enabling of the application program.
In this embodiment, when the terminal detects that the application is started, the current use state of the terminal central processing unit (CPU, central Processing Unit) is determined. And determining the starting time of the corresponding screen burn detection. In this embodiment, the start time of the burn-in detection is 10 to 15 minutes after the detected application program is started. The current usage status may be a current cpu usage as a decision factor. In this embodiment, the idle state is the use rate lower than 50%, and the non-idle state is the use rate equal to or higher than 50%. When the central processing unit is in an idle state, determining the starting time of corresponding screen burning detection to be shorter, for example, 10 minutes after the application program is started; if the central processing unit is in a non-idle state or even in a busy state, if the usage rate reaches 70%, the determined starting time of the corresponding screen burn detection is longer, for example, 15 minutes after the application program is started. This embodiment ensures that the execution of the burn-in detection does not affect the operation of the application.
On this basis, the step S110 may further include:
when the enabling duration of the application program reaches the starting time of the screen burn-in detection, determining a time interval of the screen burn-in detection for the terminal screen so as to execute the screen burn-in detection of the screen area covered by the application program.
And after the application program is started up, the terminal counts the starting time length of the application program to obtain the corresponding starting time length. When the activation time period reaches the start time of the burn-in detection determined according to the above steps, for example, 15 minutes after the application is started, the burn-in detection is started to be performed on the screen area covered by the application. And repeatedly performing screen burn-in detection on the screen area covered by the application program according to the determined time interval of the screen burn-in detection for the terminal screen so as to acquire detection data of each screen burn-in detection.
And S120, performing screen burn detection sequentially according to the time interval of the screen burn detection to obtain color values of all pixel points of a screen area covered by the application program obtained by each screen burn detection.
And according to the time interval of the screen burn-in detection determined in the step S110, the screen burn-in detection is sequentially carried out for the screen area covered by the corresponding application program. The picture in the screen display area of the terminal is composed of individual pixels. And detecting the color value of each pixel point of the screen area covered by the application program at each screen burning detection.
S130, determining color values obtained by two adjacent screen burning detection of each pixel point, and determining the screen burning risk level corresponding to the color values.
And according to the two adjacent screen burn-in detection carried out in the time interval of the screen burn-in detection, the color value of each pixel point of each screen burn-in detection is determined, and the change condition of the color value displayed by the same pixel point in the time interval of the screen burn-in detection is obtained. And determining the corresponding fire screen risk level according to the change condition of the color value.
And S140, when the accumulated value of the risk level of the burning screen of the pixel point reaches the risk set value, acquiring the contrast color of the color value of the pixel point.
And (3) carrying out accumulated statistics on the value of the screen risk level of the corresponding pixel point determined in the step (S130) to obtain a corresponding accumulated value so as to evaluate the screen risk of the terminal screen corresponding to the pixel point along with the starting duration of the application program. With the extension of the activation time of the application program, whether the burn-in screen protection needs to be started or not, in this embodiment, the risk setting value is used as a determination condition.
When the accumulated value reaches the risk set value, the problem of screen burn occurs to a large extent in the coordinate area of the corresponding pixel point in the covered screen area of the application program, and the corresponding screen burn protection means is required to be started. In this embodiment, according to the determination condition that the cumulative value reaches the risk set value, the method triggers to obtain the contrast color of the color value of the pixel point, so as to reduce the risk of screen burn of the primary color corresponding to the color value to the coordinate area of the pixel point in the terminal screen.
And S150, covering the contrast color on the coordinate area of the pixel point, so that the coordinate area of the pixel point displays the contrast color.
For the contrast color obtained in step S140, instead of displaying the primary color corresponding to the replacement color value in the coordinate area of the pixel, the contrast color is overlaid on the coordinate area of the pixel, so that the coordinate area of the pixel displays the contrast color. The display duration of the corresponding contrast color in the coordinate area of the pixel point can be determined according to the condition of screen burning detection of the corresponding application program, and the display can be carried out in a matched manner by matching with the primary colors so as to achieve the purpose of screen burning protection on the coordinate area of the pixel point in the terminal screen.
According to the screen burn-in protection method, the change condition of the color value of each pixel point can be obtained through screen burn-in detection, the pixel point with the screen burn-in risk is obtained, and the contrast color of the color value is displayed on the coordinate area of the pixel point, so that the purpose of screen burn-in protection of the coordinate area of the pixel point in the terminal screen is achieved.
Therefore, as the technical scheme of the embodiment of the invention can burn-in and protect each pixel point in the screen area covered by the application program aimed at by the burn-in detection, the negative condition that the burn-in damage is caused to the terminal screen due to the use of the corresponding application program by the user, thereby causing the loss of the user is avoided.
On the basis of the above-described embodiment of the present disclosure, the step S110 may further include:
and determining a corresponding time interval for screen burn-in detection according to the change of the display brightness value of the terminal screen.
The display brightness of the screen area and the change condition of the color value displayed in the same area are main screen burning factors, namely, the higher the brightness is, the easier the corresponding screen area generates the screen burning condition; and in the same area, the longer the same color value is displayed, the easier the corresponding screen area generates the burn-in condition.
In this embodiment, in the process of running the corresponding application program by the terminal, the display brightness value of the screen area covered by the application program is obtained, and the corresponding time interval for burn-in detection is determined according to the change of the display brightness value, such as the change trend of the increase or decrease of the display brightness. If the display brightness is increased, the corresponding time interval for screen burn detection can be shortened; and when the display brightness increases and decreases, the corresponding time interval of screen burn detection is prolonged.
On the basis, the step of determining the corresponding time interval of screen burn-in detection according to the change of the display brightness value of the terminal screen comprises the following steps:
if the current display brightness of the terminal screen is increased, the corresponding screen burning detection time interval is gradually reduced;
Or,
if the current display brightness of the terminal screen is reduced, the corresponding time interval of screen burn detection is gradually increased.
The change value of the current display brightness can be obtained by comparing the current display brightness with the brightness value detected last time or the brightness value detected at a certain time before, or can be obtained by comparing the current display brightness value with the set initial display brightness value.
And for the determination of the time interval of the screen burn-in detection, the step-type or the equal slope conversion can be performed according to a certain coefficient according to the amplitude and/or the frequency of the change value of the current display brightness of the terminal screen. The relation between the change value of the current display brightness of the specific terminal screen and the time interval of screen burning detection can be arbitrarily changed on the premise of the technical means and according to the detection requirement. In order to better explain the relationship between the change value of the current display brightness of the terminal screen and the time interval of the screen burn-in detection, an embodiment is exemplified.
For increasing the current display brightness of the terminal screen, the corresponding time interval of screen burn-in detection gradually decreases, and the method may further include:
determining an initial display brightness value Lo, a corresponding initial detection time interval To and a brightness variable preset value Lc;
Detecting that the current display brightness value L is increased relative to the initial display brightness value Lo, and determining a corresponding time interval T of screen burn detection as follows when (L-Lo)/lc=n is satisfied: t=to-n×a.
For the decrease of the current display brightness of the terminal screen, the corresponding time interval of screen burn-in detection increases gradually, and the method may further include:
detecting that the current display brightness value L is reduced relative to the initial display brightness value Lo, and determining that the corresponding time interval of screen burn detection is as follows when (Lo-L)/lc=n is satisfied: t=to+n×b.
Wherein n is a positive integer, a is a first time interval adjustment value, and b is a second time interval adjustment value.
In the present embodiment, the determined initial display luminance value Lo is 50%, and the corresponding initial detection time interval To is 20s (seconds). If the display brightness value is increased by 10%, the corresponding detection time interval is reduced by 1s. That is, the preset luminance variable value Lc is 10% and the corresponding first time interval adjustment value a is 1.
If the current display brightness value L is 70%, the (70% -50%)/10% =2, 2 satisfies the condition of being a positive integer, and the corresponding time interval of the burn-in detection is determined as follows: t=20-2*1 =18s. If the current display brightness is increased relative to the initial display brightness value Lo, the corresponding screen burn detection time interval is shortened, and the condition that the corresponding screen burn risk is not detected in time under the condition that the terminal screen performs long-time high-brightness display is avoided, so that the screen burn condition occurs.
Similarly, the determined initial display luminance value Lo is 50%, and the corresponding initial detection time interval To is 20s (seconds). If the display brightness value is reduced by 10%, the corresponding detection time interval is increased by 1s. That is, the preset luminance variable value Lc is 10% and the corresponding second time interval adjustment value b is 1.
If the current display brightness value L is 30%, the condition that (50% -30%)/10% =2, 2 is a positive integer is satisfied, and the corresponding time interval of the burn-in detection is determined as follows: t=20+2×1=22s. If the current display brightness is reduced relative to the initial display brightness value Lo, the corresponding time interval of screen burn detection is prolonged, so that the screen burn detection is prevented from being frequently executed under the condition that the terminal screen is in low-brightness display, the running resource of the central processing unit is excessively occupied, and the normal running of the application program is run.
For the above two embodiments, the first time interval adjustment value a and the second time interval adjustment value b may be inconsistent, i.e. the decrease or increase amplitude of the corresponding time interval of burn-in detection may be adjusted according to the influence of the increase or decrease amplitude of the brightness value on the terminal screen.
Referring to fig. 2, fig. 2 is a flowchart of a burn-in screen protection method according to another embodiment of the present disclosure.
Step S120 may further include:
s121, sequentially acquiring projection images of a current screen according to the time interval of screen burning detection, and calling an image reader to obtain a dot matrix image corresponding to the projection images;
s122, obtaining color values of all pixel points of the dot matrix image by using a preset function.
According to the time interval for the burn-in detection of the terminal screen determined in step S110, the screen area display area covered by the application program in the current screen may be sequentially intercepted by a media projection manager (english name: mediaProjectionManager) of the Android system, so as to obtain a projection image of the screen area covered by the application program in the current screen.
And for the screen area covered by the application program, if the application program occupies the whole screen area of the terminal, directly acquiring the whole screen area of the terminal as the screen area covered by the application program. The screen area covered by the application program is not the whole screen area of the terminal, and the plug-in can be acquired through the display area acquisition plug-in the screen burning detection program, so that the screen area covered by the application program is acquired.
After the projection image is obtained, an image reader (English name: imageReader) is called, and a corresponding dot matrix image is obtained from the projection image of the current screen. The dot matrix image is passed so that the terminal can recognize the color value of each pixel of the projected image constituting the current screen.
And acquiring color values of corresponding pixel points according to coordinate values of all pixels in the dot matrix image by using a preset function so as to determine corresponding screen burn risk levels according to color values obtained by detecting all pixel points on each screen burn, thereby starting screen burn protection of the corresponding pixel points. In this embodiment, the predetermined function may be a GetPixel function.
For the step of determining the change condition of the color value obtained by two adjacent screen burning detection of each pixel point in the step S130, and determining the screen burning risk level corresponding to the change condition of the color value, the method may further include:
if the color values obtained by two adjacent screen burning detection of the same pixel point are the same, determining that the screen burning risk level of the pixel point is a first preset value;
if the first preset value and the second preset value are different, the second preset value is determined.
In the detection of two adjacent screen burn-in processes, the color value of the same pixel point obtained by detection is unchanged, and the terminal screen can be displayed in the same color for a long time in the coordinate area of the pixel point, so that the risk of screen burn-in exists. Corresponding to the situation, confirming the screen risk level of the pixel point as a first preset value. The first preset value is used for indicating that the coordinate area of the corresponding pixel point may have a burn-in risk. If the color values of the same pixel point detected in the two adjacent screen burning detection are different, the screen burning risk level of the pixel point is confirmed to be a second preset value. The second preset value is used for indicating that the screen burning risk does not exist in the coordinate area of the corresponding pixel point.
Referring to fig. 3, fig. 3 is a schematic diagram of an editing interface of an application program according to an embodiment of the disclosure.
In the editing interface diagram of the application of fig. 3, the underlying "+" is the control of the editing tool whose position display position is fixed and whose color exhibited is not modified under normal use conditions. Therefore, the screen area corresponding to "+" is easily burned due to the long-term use of the application program. In this case, in two adjacent screen burning processes, the color value response of each pixel point of the corresponding screen area is obtained, and the corresponding screen burning risk level is a first preset value. Wherein the first preset value is greater than the second preset value.
On the basis, the device also comprises:
when the screen burning risk level of the pixel point is not smaller than a first preset value, determining that the time interval of screen burning detection for the terminal screen is a high-frequency detection time interval;
and performing screen burn detection according to the high-frequency detection time interval.
When the screen burning risk level of the corresponding pixel point is greater than or equal to a first preset value, namely the coordinate area of the corresponding pixel point may have screen burning risk. In this embodiment, the fire screen risk level of the corresponding pixel point is not less than the first preset value as a trigger condition, the high-frequency detection is started, the time interval of the fire screen detection of the terminal screen is determined to be the high-frequency detection time interval, the fire screen detection is performed according to the high-frequency detection time interval, that is, the time interval of the fire screen detection of two adjacent times is shortened, and the problem that the coordinate area of the pixel point is burnt due to the fact that the coordinate area of the pixel point displays the color corresponding to the same color value for a long time is avoided.
Further, in the present embodiment, after the high frequency detection is started, the time interval of each high frequency burn-in detection is gradually decreased according to the set ratio.
For example, the time interval Ts of the first burn-in detection after starting the high-frequency detection 1 The set ratio is 1/2, i.e., the time interval of each burn-in detection after the time interval of the first burn-in detection is 1/2 of the time interval of the previous burn-in detection. The time interval Ts for the first screen burn detection is prolonged 1 Time interval Ts of second burn-in detection 2 Time interval Ts of third burn-in detection =10 mins 3 =5 mins … …. And determining the change condition of the color value obtained by the adjacent two screen burning detection corresponding to each pixel point of the screen area covered by the application program according to the time interval of each screen burning detection, and confirming the corresponding first preset value. If the first preset value is set to 1, the second preset value is set to 0. When the color values obtained by two adjacent screen burning detection at the time interval of each screen burning detection corresponding to the same pixel point are the same, different and the same … …, the corresponding screen burning risk grades are 1, 0 and 1 … … respectively.
And aiming at the pixel point, obtaining the value of each burn-in risk grade, and accumulating to obtain a corresponding accumulated value. And when the accumulated value reaches a risk set value such as 5, triggering to acquire the current color value of the pixel point to obtain the corresponding contrast color. The contrast color is overlaid on the coordinate area of the pixel point such that the coordinate area of the pixel point exhibits the contrast color.
According to the dot matrix image obtained in the above embodiment, the color value of each pixel in the application program can be obtained, and the color value is between 0 and (-16777214). Wherein, 0 is a color value corresponding to white, and 16777214 is a color value corresponding to black. If the color value x of the pixel point is detected, wherein x is within the interval of 0 to (-16777214), and the color value of the contrast color is- (16777214+x). And covering the contrast color on the coordinate area of the corresponding pixel point according to the calculated color value of the contrast color, so that the coordinate area of the pixel point displays the contrast color.
For the step of overlaying the contrast color on the coordinate area of the pixel point in step S150, it includes:
and generating a layer on the upper layer of the screen area covered by the application program, and adding the contrast color at the position area of the coordinate area of the pixel point corresponding to the layer.
And in the running process of the application program, acquiring a window object, and generating a layer on the upper layer of the screen area covered by the application program according to the window object. In this embodiment, the layer is fully transparent and does not handle any click events that the user acts on the terminal, including the terminal screen. When the contrast color corresponding to the color value of the pixel is obtained according to step S140, the contrast color is added to the layer, and the added position corresponds to the pixel coordinate area. When the contrast color of the image layer is displayed in the pixel point coordinate area of the terminal, the color corresponding to the current color value of the application program is covered, and the display cannot be performed.
Based on this embodiment, the embodiment of the present disclosure further includes: and according to the set alternating time interval, the primary colors and the contrast colors corresponding to the color values are alternately displayed on the coordinate area of the pixel point.
In this embodiment, the alternating time interval is smaller, for example, 0.1s (second), so that the coordinate area of the pixel point can be alternately displayed with different color values in a shorter time, and the problem of screen burn caused by displaying the same color for a long time in the coordinate area of the pixel point is avoided, and the screen burn protection effect is played on the coordinate area of the pixel point.
And resetting the fire screen risk level corresponding to the pixel point to a second preset value when the accumulation of the alternating display time periods of the primary colors and the contrast colors reaches the preset alternating accumulation time period.
The alternating accumulation duration is the accumulation duration of alternating display of the primary color and the contrast color, and if the preset alternating accumulation duration is 1s, the alternating accumulation duration is satisfied when the alternating display of the primary color and the contrast color with the alternating time interval of 0.1s is performed for 5 times. And resetting the risk level of the pixel to a second preset value according to the condition that the alternate accumulation duration is satisfied, wherein the second preset value provided by the embodiment is 0. The pixel point is free from the risk of screen burn when the alternating display time length is accumulated to reach the preset alternating accumulation time length after the alternating display of the primary colors and the contrast colors. And then, re-determining the screen burn risk level of the pixel point according to the execution of any embodiment, and performing screen burn protection. Therefore, the embodiment can perform screen burning protection on the pixel points with screen burning risk in a short time, and enable the pixel points to be restored to a normal use state, and can ensure normal use of the application program besides ensuring screen burning protection of the corresponding pixel points, thereby being beneficial to improving user experience of the application program.
