Technical Field

Background

Screen burning: for a device using an OLED screen, a shadow-like background is always left when one image (e.g., a navigation button, a scoreboard, etc. on a mobile phone) is displayed at the same position of the display screen for a long time, no matter what other image is displayed on the display screen. For this phenomenon we call burn-in. The damage to the burn-in is permanent and irreversible. Therefore, the screen burning is not easy to be regarded at the early stage, but is a relatively serious problem without repair possibility after the screen burning occurs.

Because the use of OLED screens has not been widespread on all devices, and the generation of burn-in needs to depend on special scenes and heavy use, most ordinary users do not have the risk of burn-in. This problem has not been widely appreciated.

At present, only part of mobile phone manufacturers do screen burn-in prevention aiming at system level image elements such as a status bar, a navigation bar and virtual buttons, and the main scheme is to regularly move the image elements at a fine pixel point level so as to slow down screen burn-in. But the larger the screen used is the application software. The application software can not generally carry out the screen burning prevention protection, and the screen burning phenomenon is probably caused due to the long-time use of the application software.

Referring to fig. 1, fig. 1 is a flowchart of a burn-in protection method according to an embodiment of the present disclosure.

And S110, determining a time interval of screen burning detection aiming at the terminal screen.

The screen burning detection is to detect the change condition of the color value displayed by the same pixel point within a certain time period. That is to say to same pixel point, burn the screen detection twice at least to obtain corresponding colour value. And determining the corresponding screen burning risk according to the color values detected by the two screen burning. The time interval between the two screen burning detections is the time interval of the screen burning detection.

Therefore, in the process of the screen burn-in detection, the time interval of the screen burn-in detection for the screen needs to be determined according to the use condition of the terminal screen.

Before the step, the method also comprises the following steps:

and when the application program is detected to be started, determining the corresponding starting time of the screen burning detection according to the current use state of the central processing unit of the terminal.

The starting time of the screen burning detection is the running condition of the application program, and the running condition can include the change condition of the color value of the pixel point of the application program and the running condition of the application program, and even can be determined by combining the running condition of the current terminal.

When a user sends an enabling instruction to the application program to the terminal, 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 enabled, the current usage status of the terminal Central Processing Unit (CPU) is used. And determining the starting time of the corresponding screen burning 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 the current utilization of the central processing unit as a decision factor. In this embodiment, the idle state is defined as a state in which the usage rate is lower than 50%, and the non-idle state is defined as a state in which the usage rate is equal to or higher than 50%. When the central processing unit is in an idle state, determining the starting time of the corresponding screen burning detection to be shorter time, such as 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 utilization rate reaches 70%, the determined starting time of the corresponding screen burning detection is a longer time, such as 15 minutes after the application program is started. The embodiment can ensure that the execution of the burn-in detection does not affect the operation of the application program.

On this basis, the step S110 may further include:

and when the starting duration of the application program reaches the starting time of the screen burning detection, determining the time interval of the screen burning detection aiming at the terminal screen so as to execute the screen burning detection of the screen area covered by the application program.

And after the application program is started after detection, the terminal times the starting time of the application program to obtain the corresponding starting time. When the starting time reaches the starting time of the screen burning detection determined according to the above steps, for example, after 15 minutes after the application program is started, the screen burning detection is started to be performed on the screen area covered by the application program. And repeatedly executing the screen burning detection on the screen area covered by the application program according to the determined time interval of the screen burning detection aiming at the terminal screen so as to obtain the detection data of each screen burning detection.

And S120, sequentially carrying out screen burning detection according to the time interval of the screen burning detection so as to obtain the color value of each pixel point of the screen area covered by the application program, which is obtained by each screen burning detection.

And sequentially performing screen burning detection on the screen areas covered by the corresponding application programs according to the time interval of the screen burning detection determined in the step S110. The picture in the screen display area of the terminal is composed of all pixel points. And when each screen burning detection is carried out, detecting the color value of each pixel point of the screen area covered by the application program.

S130, determining color values obtained by two adjacent screen burning detections of each pixel point, and determining a screen burning risk grade corresponding to the color values.

And according to the adjacent twice screen burning detection carried out at the time interval of the screen burning detection, determining the color value of each pixel point of each screen burning detection, and obtaining the change condition of the color value displayed by the same pixel point in the time interval of the screen burning detection. And determining the corresponding burning screen danger grade according to the change situation of the color value.

S140, when the accumulated value of the burn screen risk grade of the pixel reaches a risk set value, obtaining the color value of the pixel.

And performing cumulative statistics on the value of the screen burning risk grade of the corresponding pixel point determined in the step S130 to obtain a corresponding cumulative value, so as to evaluate the screen burning risk of the pixel point corresponding to the starting duration of the terminal screen along with the application program. In the present embodiment, a risk setting value is used as a determination condition as to whether or not the burn-in protection needs to be started as the activation time of the application program increases.

When the accumulated value reaches the risk set value, the problem of screen burning occurs to a great extent in the coordinate area of the corresponding pixel point in the screen area covered by the application program, and a corresponding screen burning protection means needs to be started. In this embodiment, according to the determination condition that the accumulated value reaches the risk set value, the reverse differential color of the color value of the pixel point is triggered to be obtained, so as to reduce the screen burning risk of the primary color corresponding to the color value to the coordinate region of the pixel point in the terminal screen.

S150, covering the contrast color on the coordinate area of the pixel point, so that the coordinate area of the pixel point shows the contrast color.

For the contrast color obtained in step S140, instead of displaying the primary color corresponding to the color value in the coordinate region of the pixel point, the contrast color is covered on the coordinate region of the pixel point, so that the coordinate region of the pixel point 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 screen burning detection condition of the corresponding application program, and the display can be matched with the primary color to achieve the purpose of screen burning protection of the coordinate area of the pixel point in the terminal screen.

According to the screen burning protection method, the change condition of the color value of each pixel point can be acquired through screen burning detection, the pixel points with screen burning risks are acquired, and the contrast color of the color value is displayed in the coordinate area of the pixel point, so that the purpose of screen burning protection of the coordinate area of the pixel point in a terminal screen is achieved.

On the basis of the above embodiments of the present disclosure, the step S110 may further include:

and determining the corresponding time interval of the screen burning detection according to the change of the display brightness value of the terminal screen.

The display brightness of the screen area and the change situation of the color value displayed in the same area are main screen burning factors, namely the higher the brightness is, the more easily the screen burning situation is generated in the corresponding screen area; and in the same area, the longer the time for displaying the same color value is, the more easily the screen burning condition is generated in the corresponding screen area.

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 of the burn-in detection is determined according to a change of the display brightness value, such as a change trend of increase or decrease of the display brightness. If the display brightness is increased, the corresponding time interval of screen burning detection can be shortened; when the display brightness is increased or decreased, the time interval of the corresponding screen burning detection is prolonged.

On the basis, the step of determining the corresponding time interval of the 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 time interval of the corresponding screen burning detection is gradually reduced;

or,

and if the current display brightness of the terminal screen is reduced, the time interval of the corresponding screen burning detection is gradually increased.

The change value for measuring the current display brightness may be obtained by comparing with the brightness value detected last time or the brightness value detected some time before, or may be obtained by comparing with the set initial display brightness value.

And for the determination of the time interval of the screen burning detection, the constant slope conversion can be performed in a step mode or 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 relationship between the current display brightness variation value of the terminal screen and the time interval of the screen burning detection can be arbitrarily changed according to the detection requirement on the premise of the technical means. In order to better explain the relationship between the current display brightness variation value of the terminal screen and the time interval of the screen burning detection, an embodiment is exemplified.

For the increase of the current display brightness of the terminal screen, the corresponding time interval of the burn-in detection is gradually decreased, which 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 to obtain that the current display brightness value L is increased relative to the initial display brightness value Lo, and when (L-Lo)/Lc ═ n is satisfied, determining that the corresponding time interval T of the burn-in detection is as follows: T-To-n a.

For the decrease of the current display brightness of the terminal screen, the corresponding time interval of the burn-in detection is gradually increased, which may further include:

and detecting to obtain that the current display brightness value L is reduced relative to the initial display brightness value Lo, and when (Lo-L)/Lc ═ n is satisfied, determining that the corresponding time interval of the burn-in detection is as follows: 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%, which corresponds To an initial detection time interval To of 20s (seconds). If the display brightness value increases by 10%, the corresponding detection time interval decreases by 1 s. I.e. the preset value Lc of the brightness variation is 10%, the corresponding first time interval adjustment value a is 1.

If the current display brightness value L is 70% (70% -50%)/10% ═ 2, 2 satisfies a condition of a positive integer, and the corresponding time interval of the burn-in detection is determined as: t-20-2 x 1-18 s. That is, if the current display brightness is increased relative to the initial display brightness value Lo, the time interval of the corresponding screen burning detection is shortened, and the situation that the screen burning is caused because the corresponding screen burning risk is not detected in time under the condition that the terminal screen is subjected to long-time high-brightness display is avoided.

Likewise, the determined initial display luminance value Lo is 50%, which corresponds To an initial detection time interval To of 20s (seconds). If the display brightness value decreases by 10%, the corresponding detection time interval increases by 1 s. I.e. the preset value Lc of the brightness variation is 10%, the corresponding second time interval adjustment value b is 1.

If the current display brightness value L is 30%, then (50% -30%)/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: t20 +2 × 1 ═ 22 s. Namely, if the current display brightness is reduced relative to the initial display brightness value Lo, the time interval of the corresponding screen burning detection is prolonged, and the situation that the screen burning detection is frequently executed under the condition that the terminal screen is in low-brightness display, the running resources of the central processing unit are excessively occupied, and the normal running of the application program is run is avoided.

For the two embodiments, the first time interval adjustment value a and the second time interval adjustment value b may not be consistent, that is, the decrease or increase of the corresponding burn-in detection time interval may be adjusted according to the influence of the increase or decrease of the brightness value on the terminal screen.

Referring to fig. 2, fig. 2 is a flowchart of a burn-in protection method according to another embodiment of the disclosure.

The step S120 may further include:

s121, sequentially acquiring projected images of a current screen according to the time interval of screen burning detection, and calling an image reader to obtain dot matrix images corresponding to the projected images;

and S122, obtaining the color value of each pixel point of the dot matrix image by using a preset function.

According to the time interval determined in step S110 for the burn-in detection of the terminal screen, a media projection manager (having a name of mediaproject manager) of the Android system may sequentially intercept a screen region display region covered by the application program in the current screen, so as to obtain a projected image of the screen region covered by the application program in the current screen.

For the screen area covered by the application program, if the application program occupies the whole screen area of the terminal, the whole screen area of the terminal is directly acquired 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 in the burn-in detection program to acquire the screen area covered by the application program.

After the projection image is obtained, an image reader (English name: Imagereader) is called to obtain a corresponding dot matrix image from the projection image of the current screen. Through the dot matrix image, the terminal can identify the color value of each pixel point forming the projected image of the current screen.

And acquiring color values of corresponding pixel points according to the coordinate values of all the pixels in the dot matrix image by using a preset function, so as to determine corresponding screen burning danger grades according to the color values of all the pixel points detected by screen burning at each time, and starting screen burning protection of the corresponding pixel points. In this embodiment, the predetermined function may be a GetPixel function.

The step of determining the change condition of the color value obtained by two adjacent screen-burning detections of each pixel point in the step S130, and determining the screen-burning risk level corresponding to the change condition of the color value, may further include:

if the color values obtained by two adjacent screen burning detections of the same pixel point are the same, determining the screen burning risk grade of the pixel point to be a first preset value;

if not, determining the value as a second preset value.

In the two adjacent screen burning detections, the color value of the same detected pixel point is unchanged, and the terminal screen may be displayed in the same color for a long time in the coordinate area of the pixel point, so that the screen burning risk exists. And corresponding to the situation, determining the screen burning danger grade of the pixel point as a first preset value. And the first preset value is used for indicating that the coordinate area of the corresponding pixel point possibly has a screen burning risk. And if the color values of the same detected pixel point are different in the two adjacent screen burning detections, determining the screen burning danger grade of the pixel point as 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 present disclosure.

In the editing interface diagram of the application of FIG. 3, the "+" underlying control of the editing tool whose display position is fixed and whose color of presentation is not modified in general use. Therefore, the screen burning problem is easily caused to the screen area corresponding to the "+" due to the long-time use of the application program. In response to the situation, in two adjacent screen burning processes, the color values of the pixel points corresponding to the screen area are obtained to respond, and the corresponding screen burning risk grade is a first preset value. Wherein the first preset value is larger than the second preset value.

On this basis, still include:

when the screen burning risk grade of the pixel point is not smaller than a first preset value, determining the time interval of screen burning detection aiming at the terminal screen as a high-frequency detection time interval;

and performing screen burn-in detection according to the high-frequency detection time interval.

When the screen burning danger level of the corresponding pixel point is larger than or equal to the first preset value, screen burning danger may exist in the coordinate area of the corresponding pixel point. In this embodiment, the screen burning risk level of the corresponding pixel point is not less than the first preset value as a trigger condition, high-frequency detection is started, the time interval for screen burning detection of the terminal screen is determined as a high-frequency detection time interval, screen burning detection is performed according to the high-frequency detection time interval, namely, the time interval for two adjacent screen burning detections is shortened, and the problem of screen burning caused by 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 this embodiment, after the high frequency detection is started, the time interval of each high frequency burn-in detection is gradually decreased according to a set ratio.

Such as time interval Ts for the first burn-in test after the high frequency test is initiated₁The set ratio is 1/2, that is, the time interval of each burn-in test after the time interval of the first burn-in test is 1/2 of the time interval of the previous burn-in test, which is 20mins (minutes). Time interval Ts for the first burn-in test provided above₁Time interval Ts of the second burn-in test₂Time interval Ts of the third burn-in test of 10mins₃5mins … …. And determining the change condition of the color value obtained by the two adjacent screen burning detections 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 determining 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 detections corresponding to the time interval of each screen burning detection of the same pixel point are same, different and same … …, the corresponding screen burning risk grades are 1, 0 and 1 … … respectively.

And (4) obtaining the value of each screen burning danger grade for the pixel point, 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. And covering the reverse color difference on the coordinate area of the pixel point, so that the coordinate area of the pixel point shows the reverse color difference.

According to the dot matrix image obtained in the embodiment, the color value of each pixel point in the application program can be obtained, and the color value is in the interval from 0 to (-16777214). Where 0 is the color value for white and-16777214 is the color value for black. Corresponding to a pixel, if the color value x is detected, wherein x is in the range of 0 to (-16777214), the color value of the reverse color is- (16777214+ x). And covering the contrast color on the coordinate area of the corresponding pixel point according to the color value of the calculated contrast color, so that the coordinate area of the pixel point shows the contrast color.

For the step of covering the contrast color on the coordinate area of the pixel point in step S150, the method includes:

and generating a layer on the upper layer of the screen area covered by the application program, and adding the reverse color at the position area of the coordinate area of the pixel point corresponding to the layer.

In the running process of the application program, a window object is obtained, and a layer is generated on the upper layer of a 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 user action on the terminal, including click events on the terminal screen. When the contrast color of the color value of the corresponding pixel point is obtained according to step S140, the contrast color is added to the layer, and the added position corresponds to the coordinate region of the pixel point. When the pixel point coordinate area of the terminal is displayed by the contrast color of the layer, 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 alternately displaying primary colors and reverse differential colors corresponding to the color values in the coordinate region of the pixel point according to the set alternate time interval.

In this embodiment, this alternate time interval is smaller, like 0.1s (second) for the coordinate region of this pixel can be in turn shown with different colour values in shorter time, avoids the coordinate region of this pixel to cause the problem of burning the screen because of the same colour of long-time show, plays the effect of burning the screen protection to the coordinate region of this pixel.

And when the accumulation of the alternate display time lengths of the primary colors and the reverse colors reaches the preset alternate accumulation time length, resetting the burning screen danger grade corresponding to the pixel point to be a second preset value.

The alternate accumulated duration is the accumulated duration of alternate display of the primary color and the reverse differential color, and if the preset alternate accumulated duration is 1s, the alternate accumulated duration is satisfied when the alternate display of the primary color and the reverse differential color with the alternate time interval of 0.1s is performed for 5 times. According to the condition that the alternate accumulated time duration is satisfied, the risk level of the pixel point is reset to a second preset value, wherein the second preset value provided by the embodiment is 0. Namely, the primary colors and the reverse colors are alternately displayed, and the time accumulation of the alternate display reaches the preset alternate accumulation time, so that the screen burning risk does not exist in the pixel point. And then, according to the execution of any one of the above embodiments, re-determining the screen burning risk level of the pixel point, and performing screen burning protection. Therefore, the embodiment can perform screen burning protection on the pixel points with the screen burning risk in a short time, and restore the pixel points to a normal use state again, so that the normal use of the application program can be ensured besides the screen burning protection of the corresponding pixel points, and the user experience of the application program is promoted.
