Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
For the conventional display device, an Organic Light Emitting Diode (OLED), which is a current type Light emitting device, is increasingly used in the high performance display field due to its characteristics of self-luminescence, fast response, wide viewing angle, and being capable of being fabricated on a flexible substrate. However, the OLED display screen may suffer from attenuation during use, which may affect the display effect of the screen. Particularly, in some areas displaying high contrast for a long time, with the aging of pixels, phenomena such as image sticking and the like can occur, and even screen burn occurs to cause the problem of yellowing of screen display.
At present, most mobile phone manufacturers often add an option at a system end to automatically turn off a screen in order to avoid that a display screen burns or the endurance of a mobile phone is affected due to the fact that the mobile phone is not used by a person for a long time. There are also differences in the time interval options for automatic screen off by the manufacturers, and there is no uniform standard, for example, some manufacturers may keep the screen permanently off, or set the maximum screen off time to 5 minutes, etc. Therefore, the logic strategy that each mobile phone manufacturer aims at automatic screen off is different, and some manufacturers can keep the function of a permanent screen-off option, so that if a user selects the option, screen burn-in is not improved basically. Therefore, the related art has poor effects on improving the aging, screen burning and the like of the screen pixels.
In view of the above problems, the inventor provides a screen control method, a device, an electronic device, and a storage medium provided in this embodiment of the present application, which can control a region with a higher contrast to move when a duration of the electronic device in an unused state is shorter than a first duration, and can allocate aging of pixels in the region with the higher contrast to other regions, delay aging of pixels in a screen, improve an afterimage to a certain extent, and improve a display effect. The specific screen control method is described in detail in the following embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a screen control method according to an embodiment of the present application. In a specific embodiment, the screen control method is applied to the screen control device 400 as shown in fig. 11 and the electronic apparatus 100 (fig. 12) equipped with the screen control device 400. The following will describe a specific flow of the embodiment by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a smart watch, a notebook computer, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the screen control method may specifically include the following steps:
step S110: and acquiring the equipment state data of the electronic equipment under the condition that the screen is in a bright screen state.
In the embodiment of the application, the electronic device can monitor the screen state of the electronic device, so that the display of the screen is correspondingly controlled under the condition that the screen is in the bright screen state, and the problems of aging and screen burning of pixels of the screen are solved. The screen state refers to the working state of a screen of the electronic equipment; the screen state may include a screen-on state and a screen-off state, the screen-on state refers to an operating state when a screen of the electronic device is lit, and the screen-off state refers to an operating state when the screen of the electronic device is extinguished. Alternatively, the screen may be an OLED screen, such as an Active-matrix organic light-emitting diode (AMOLED) screen, a conventional OLED screen, and the like, which are not limited herein.
In some implementations, the electronic device can obtain the screen state in a variety of ways. Optionally, the operating system reads the corresponding parameter value to determine the screen state of the electronic device according to the read parameter value. As an implementation manner, when the system installed in the electronic device is an Android (Android) system, the screen state may be obtained by an issscreen on method of PowerManager, that is, by obtaining a value of issscreen on, if the value of issscreen on is true, the screen of the electronic device is in a bright screen state, and if the value of issscreen on is false, the screen of the electronic device is in a screen-off state. As another embodiment, the electronic device may also determine the screen state of the electronic device by acquiring the brightness value of the screen and according to the brightness value of the screen. For example, if the brightness value of the screen is 0, it indicates that the screen is in the off-screen state, and if the brightness value of the screen is greater than 0, the screen is in the on-screen state. Of course, the manner of specifically detecting the screen status of the electronic device may not be limiting.
In the embodiment of the application, under the condition that the screen of the electronic device is in the bright screen state, the screen may not be used by the user, and if the screen continues to work according to the previous display state, the aging speed of the pixels of the screen is accelerated, so that the screen burning is caused. Therefore, the electronic device can acquire the device state data of the electronic device when the screen of the electronic device is in the bright screen state, so as to determine whether the electronic device is in the unused state according to the device state data, and therefore, the display of the screen can be controlled when the electronic device is in the unused state.
The device status data may be status data for determining a usage status of the electronic device. The device status data may include: touch data of a screen, data of an Application Processor (AP), image data photographed by a camera, and the like, and specific device status data may not be limited.
Step S120: and if the electronic equipment is determined to be in the unused state based on the equipment state data, acquiring the time length of the electronic equipment in the unused state as the target time length.
In the embodiment of the application, after the electronic device acquires the device state data, whether the electronic device is in an unused state or not can be determined based on the device state data, so that the display of the screen is controlled according to the determination result. The electronic device may determine whether the electronic device is in an unused state based on at least one of data of the application processor, image data captured by the camera, and touch data of the screen.
In some embodiments, the device state data may include touch data, and the electronic device may determine a usage state of the electronic device based on the touch data. It can be understood that, in the bright screen state of the electronic device, if the finger of the user touches the touch screen, the logic of the touch screen is to report the coordinates and the raw data value in real time, and the click operation/sliding operation (different positions, different lengths, different radians, etc.) can be presented through the raw data. When a click operation or a slide operation is detected, it may be determined that the user is using the electronic device at that time; when the click operation or the slide operation is not detected, the electronic device is in an unused state. The raw data can be changed during the sliding operation or the clicking operation, although the positions and shapes of the actual application clicking and sliding are different, the AP can determine the touch characteristic value corresponding to the touch data and judge whether the touch characteristic value meets the characteristic value corresponding to the clicking operation or the sliding operation; the characteristic value corresponding to the click operation mainly appears as a numerical value mutation in a concentrated area, and the characteristic value corresponding to the slide operation mainly appears as a data mutation in a horizontal or vertical shape (if a broken line exists in the middle, the characteristic value can be determined), and of course, the characteristic value corresponding to the click operation and the characteristic value corresponding to the slide operation can also be determined according to historical touch data of a user when the user uses the electronic device.
In other embodiments, the device status data may include AP data. When the electronic device displays content, all data on the Display screen is output to a Random Access Memory (RAM) of a Display driver Integrated Circuit Chip (DDIC) of the Display screen through a hardware communication mode in a data format such as MIPI (Mobile Industry Processor Interface alliance)/RGB (Mobile Industry Processor Interface) by the AP (if there is no RAM, there is generally a buffer), and all data transmission can be recognized by the AP. If the display screen is changing data all the time, the AP end is in working state all the time, data are continuously updated in an iterative mode, if the display screen is kept unchanged at the moment or when the display screen is changed periodically, RGB data or MIPI data of the AP end and the data end are in Idle state at the moment. Taking MIPI data as an example, as shown in fig. 2, fig. 2 shows a phase relationship between MIPI and TE, if TE is at a low level, MIPI is also at a low level for several times, it indicates that data is continuously updated iteratively, if TE is at a low level, MIPI level is at a high level, it indicates that data is not updated, and the display end calls a data source stored in a DDIC end RAM or Flash at this time. Based on this, the AP end can determine whether the picture of the screen is in a static picture or a cyclic period square wave-fixed video or small animation (i.e., a repeatedly cyclic display picture) by monitoring the data change, and then determine whether the picture is in an unrefreshed state. If the picture of the screen is determined to be a static picture or a repeatedly-circulated display picture based on the AP data, the picture is in a state of not updating at the moment, and therefore it can be determined that the user does not use the electronic equipment; on the contrary, if the AP data determines that the screen is not a static screen and is not a repeat loop display screen, it indicates that the screen is in an updated state, and thus it can be determined that the user is using the electronic device.
In still other embodiments, the device status data may include image data captured by a camera. Optionally, the electronic device may include a front camera, and the electronic device may acquire an image through the front camera; the electronic equipment can determine whether a face exists in the image according to the image data acquired by the front camera, if the face exists, the electronic equipment is in a use state, otherwise, the electronic equipment is not in the use state. It can be understood that, if the user is using an electronic device, typically a face front-view screen, if the electronic device supports face recognition, it may be determined whether there is facial feature data at this time; if the facial feature data are detected, the electronic equipment is in a use state, otherwise, the electronic equipment is in an unused state.
As a possible implementation manner, when the electronic device detects that a human face exists in an acquired image, whether the human eye is in a closed state or not can be determined according to a human face region in a continuously acquired multi-frame image; if the human eyes in the continuous multi-frame images are all in the closed state, the user can be determined to be in the sleep state, and the electronic equipment can also be determined to be in the unused state at the moment; if the human eyes in the continuous multi-frame images are not in the closed state in each frame of image, the electronic equipment can be determined to be in the use state.
In still other embodiments, when the device state data includes touch data, if there is point reporting data at the edge of the screen in the data reported to the AP by the touch screen, it indicates that there is a holding action at this time, that is, the electronic device is in a holding state, and in this case, it may be determined that the electronic device is in a use state; if the report data of the screen edge does not exist, the electronic equipment is not in the holding state at the moment, and the electronic equipment can be judged to be in the unused state.
It should be noted that the above embodiments may also be combined to determine the use state of the electronic device. It can be understood that whether the electronic device is in the use state is determined by the mode of acquiring images through the front camera, a face image which cannot be acquired due to the fact that a user does not have a front view plane may occur, and whether the electronic device is in the use state is determined by the report data at the edge of the screen, the electronic device may be fixed by the insulating support and the report data at the edge of the screen may not occur, so that the electronic device can be determined whether the electronic device is in the use state by combining the modes.
Optionally, according to the touch data, when a click or a slide is not detected, whether the display screen is a display screen or a still screen in a repeated cycle may be determined according to the AP data; if the images are repeatedly circulated display images or static images, whether the images contain human faces or not can be further determined according to the images collected by the front camera, and whether data reported by the edge of the screen exists or not can be further determined according to the touch data; if the image does not contain the face and no data reported by the screen edge exists, the electronic equipment can be determined to be in an unused state. That is to say, it is determined that the electronic device is in an unused state only when the click or the sliding is not detected at the same time, the display picture is a repeatedly-circulated display picture or a static picture, the image acquired by the front camera does not include a human face, and no data reported by the edge of the screen exists, so that the use state of the electronic device is accurately determined.
Optionally, at present, short video applications are popular, and the influence on screen burn-in is mainly caused by the short video applications, because if the short video applications play the same video in a self-loop manner, and a user leaves the electronic device, and according to the screen-off strategy of the existing electronic device, the screen cannot be turned off according to normal logic, that is, the video may be played all the time, and the possibility of screen burn-in is increased. Therefore, with reference to the above four embodiments, with the first embodiment, based on the touch data of the screen, it is determined whether the feature value corresponding to the touch data meets the feature value corresponding to the click operation or the slide operation; then, if the characteristic value corresponding to the touch data does not satisfy the characteristic value corresponding to the click operation or the slide operation, according to the second embodiment, it is determined that the display screen is a fixed-cycle screen based on the data of the application processor, and when the cycle number exceeds or exceeds N, N is a positive integer, and N can be freely defined according to the use habit of the user, for example, set to 3 or other values, which is not limited herein. Because some users may prefer to repeat the circular playing, but there are also touch screens, such as a sliding progress bar, in general, through the two embodiments, it can be basically determined whether the user is using at the moment. On the basis, in combination with the third embodiment and the fourth embodiment, when the characteristic value corresponding to the touch data does not satisfy the characteristic value corresponding to the click operation or the slide operation, and the image displayed on the screen is determined to be repeatedly circulated to the display image based on the data of the application processor, when it is determined that the image acquired by the front camera does not include a human face, and it is determined that the electronic device is not in the holding state based on the touch data, it is determined that the electronic device is in the unused state, and thus the state where the electronic device is not used by the user, that is, the electronic device is in the unused state, can be accurately determined.
In this embodiment, the electronic device determines whether it is in an unused state through the above-mentioned combined embodiment, and therefore, before the electronic device determines whether it is in an unused state through the above-mentioned combined embodiment, it may also determine whether the application currently running in the foreground is an application of a short video through the AP data. The electronic device may pre-store application information of a large number of short video applications, and if the application information of the application program running in the foreground is matched with the application information of the large number of short video applications stored in advance, the above-mentioned combined implementation mode may be adopted to determine whether the electronic device is in an unused state; if the application information of the application program running in the foreground is not matched with the application information prestored with a large number of short video applications, at least one of the foregoing embodiments may be adopted to determine whether the electronic device is in an unused state, for example, determine whether a touch characteristic value corresponding to the touch data of the screen satisfies a characteristic value corresponding to a click operation or a slide operation, and if the touch characteristic value corresponding to the touch data of the screen does not satisfy the characteristic value corresponding to the click operation or the slide operation, determine that the electronic device is in the unused state. Of course, the specific implementation manner of determining whether the electronic device is in the unused state according to the device state data of the electronic device in the embodiment of the application may not be limited.
In the embodiment of the application, when the electronic device determines that the electronic device is in the unused state based on the device state data, timing can be started, so that the time length of the electronic device in the unused state can be obtained through timing. Therefore, under the condition that the electronic equipment is in the unused state, the time length of the electronic equipment in the unused state can be acquired at any time, and the time length is taken as the target time length, so that different control can be performed on the screen according to the time length of the electronic equipment in the unused state.
Step S130: and if the target duration is less than the first duration, controlling a pixel point of a target area in a display picture of the screen to move, wherein the contrast of the target area is greater than a preset contrast.
In the embodiment of the application, after the target duration of the electronic equipment in the unused state is obtained, whether the target duration is less than a first duration or not can be determined; in the case where the target time period during which the electronic device is in the unused state is shorter than the first time period, it means that the time period during which the user does not use the electronic device is short, and at this time, the user may leave for a short time, and he may use the electronic device again at any time. Therefore, in this case, the pixel points of the target area with the contrast greater than the preset contrast in the display image of the screen can be controlled to move, so that the aging of the pixels of the target area can be distributed to the adjacent area, thereby delaying the aging of the pixels of the screen and screen burn-in, and improving the displayed afterimage to a certain extent.
The contrast refers to the measurement of different brightness levels between the brightest white and the darkest black in a bright and dark area in an image, the larger the difference range is, the larger the contrast is, and the smaller the difference range is, the smaller the contrast is; in one possible implementation, when acquiring the region with the contrast greater than the preset contrast, the electronic device may equally divide the display screen into a plurality of regions, determine the contrast for each region, and then determine the region with the contrast greater than the preset contrast from the plurality of regions. The size of the region and the size of the preset contrast may not be limited.
In some embodiments, the electronic device controls the pixel points in the target area to move in the display frame of the screen, where the pixel points in the target area may be controlled to move in a row direction or a column direction. When the pixel points of the control target area move along the row direction, the pixel points of the control target area can be moved to the left or to the right by j rows of pixel points; when the pixel points of the control target area move along the column direction, the pixel points of the control target area can be controlled to move up or down by k rows of pixel points. Wherein j and k are positive integers, and specific numerical values thereof are not limited, and may be, for example, 1, 3, 5, 8, and the like. Alternatively, j and k may not exceed a set threshold to ensure that the target area is not shifted too much, thereby avoiding being perceived by the user in some situations, such as when the user happens to use the electronic device again, to avoid the user perceiving the shift in the target area.
For example, referring to fig. 3 and fig. 4 together, fig. 3 is a schematic diagram of the target area B when the target area B is not moved, and the target area B in fig. 4 can move by 1 pixel point to the right along the row direction; referring to fig. 3 and 5, the target area B in fig. 5 can move 1 pixel point to the left along the row direction; referring to fig. 3 and fig. 6, the target area B in fig. 6 can be moved down by 1 pixel point along the row direction; referring to fig. 3 and 7, the target area B in fig. 7 can be moved up by 1 pixel along the column direction.
In a possible implementation manner, the electronic device may control the original position of the pixel point of the target area relative to the target area to move back and forth along the row direction or the column direction, so that the aging of the screen pixel and the screen burn-in may be effectively delayed. For example, the pixel points in the target area can be controlled to move j columns of pixel points to the left, then move j columns of pixel points to the right, return to the original position, then move j columns of pixel points to the right, then move j columns of pixel points to the left, return to the original position, then move j columns of pixel points to the left, and repeat the steps, so that the pixel points in the target area can move back and forth along the row direction.
For example, referring to fig. 8, when the electronic device is a smartphone, wifi icon a1, signal strength icon a2, battery level icon A3 and other icons with higher contrast and displayed for a long time are displayed on the upper edge of an interface a1 displayed on a screen of the electronic device, and pixels in the areas of the icons generally age more heavily, so that when the target duration of the electronic device in an unused state is less than the first duration, pixel points in the areas where the icons are located may be moved to delay aging and screen burn-in of the screen pixels, and improve the displayed afterimage to a certain extent.
According to the screen control method provided by the embodiment of the application, under the condition that the duration of the electronic equipment in the unused state is less than the first duration, the area with the higher contrast is controlled to move, the aging of pixels in the area with the higher contrast can be shared in other areas, the aging of pixels of a screen is delayed, the ghost is improved to a certain extent, and the display effect is improved.
Referring to fig. 9, fig. 9 is a schematic flowchart illustrating a screen control method according to another embodiment of the present application. The screen control method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 9, and the screen control method may specifically include the following steps:
step S210: and acquiring the equipment state data of the electronic equipment under the condition that the screen is in a bright screen state.
Step S220: and if the electronic equipment is determined to be in the unused state based on the equipment state data, acquiring the time length of the electronic equipment in the unused state as the target time length.
In the embodiment of the present application, steps S210 to S220 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S230: and if the target duration is less than the first duration, acquiring an area with the contrast ratio greater than a preset contrast ratio from the display picture of the screen as a target area.
In the embodiment of the application, when the target duration of the unused state of the electronic device is less than the first duration, it indicates that the duration of the unused state of the electronic device by the user is short, and at this time, the user may leave briefly, and the user may reuse the electronic device at any time. In this case, an area having a contrast greater than a preset contrast may be acquired from a display screen of the screen, and the determined area may be used as the target area.
Step S240: determining a movement amount by which the target region is to be moved as a target movement amount based on the resolution of the screen and the direction in which the target region is to be moved.
In the embodiment of the application, when the electronic device controls the pixel point of the target area to move, the amount of movement to be moved of the target area can be determined. The electronic device may determine a movement amount by which the target area is to be moved based on the resolution of the screen and the direction in which the target area is to be moved, and use the determined movement amount as the target movement amount. It can be understood that the resolution of the screen is related to the pixels included in the screen, and the number of the pixels in the row direction is different from that in the column direction, that is, the number of the rows and the columns is different, so that in order to avoid being perceived by a user after moving the target area, the amount of movement of the target area can be determined based on the resolution of the screen and the direction in which the target area is to be moved.
In some embodiments, the electronic device, based on the resolution of the screen and the direction in which the target region is to be moved, determining, as the target movement amount, a movement amount by which the target region is to be moved may include: determining a number of column pixels of the screen as a first number and a number of row pixels of the screen as a second number based on a resolution of the screen; if the direction in which the target area is to be moved is a row direction, determining the movement amount of the target area to be moved as a target movement amount based on a preset offset ratio and the first number; and if the direction of the target area to be moved is the column direction, determining the movement amount of the target area to be moved as a target movement amount based on the preset offset ratio and the second amount. It is to be understood that, in this embodiment, the number of column pixels of the screen determines the movement range in the row direction, and the number of row pixels of the screen determines the movement range in the column direction, and therefore, when the direction in which the target region is to be moved is the row direction, the amount of movement by which the target region is to be moved may be determined based on the first number and the preset shift ratio, and when the direction in which the target region is to be moved is the column direction, the amount of movement by which the target region is to be moved may be determined based on the second number and the preset shift ratio. The preset offset proportion can be set based on the resolution of the screen, wherein the preset offset proportion can be in positive correlation with the resolution of the screen, namely the larger the resolution of the screen is, the larger the preset offset proportion is, so that the problems of screen aging and screen burning can be improved, and the movement of a picture visible to naked eyes is avoided.
In a possible implementation manner, when the direction to be moved of the target area is a row direction, a product of the first number and a preset offset ratio may be obtained to obtain a movement amount to be moved of the target area; when the direction in which the target area is to be moved is the column direction, the product of the second number and the preset offset ratio may be obtained, so as to obtain the amount of movement in which the target area is to be moved. Optionally, there may be a case where the obtained product is a decimal, and at this time, the decimal part may be ignored, so as to avoid exceeding the offset range corresponding to the preset offset ratio. For example, for a screen with a resolution of 1080 × 1920, the preset offset ratio may be 1%, the first number is 1080, and the second number is 1920, so that the moving amount of the line direction movement may be 1080 × 1% — 10.8, and at this time, the decimal portion, that is, the moving amount of the line direction movement may be 10; the amount of movement of column direction movement may be 1920 × 1% to 19.2, where the fractional part, i.e., the amount of movement of column direction movement, may be ignored, and is 19.
Step S250: and moving the pixel points of the target area by the target movement amount according to the direction.
In the embodiment of the present application, the direction in which the target area is to be moved may be preset, and may be a row direction or a column direction. When the electronic equipment moves the pixel points of the target area by the target movement amount according to the direction, the pixel points of the target area can be controlled to reciprocate by the target movement amount along the row direction or the column direction relative to the original position of the target area, so that the aging of the pixels of the screen and the screen burn-in can be effectively delayed.
In some embodiments, the direction of the movement of the pixel points of the target area may include both the row direction and the column direction. In this case, in step S240, a moving amount corresponding to the row direction may be determined as the first moving amount and a moving amount corresponding to the column direction may be determined as the second moving amount, respectively, in the row direction and the column direction. When the pixel point of the control target area moves, the pixel point of the control target area can be controlled to perform a reciprocating process of moving the first movement amount once along the row direction relative to the original position of the target area, then perform a reciprocating process of moving the second movement amount once along the column direction, perform a reciprocating process of moving the first movement amount once along the row direction, and repeat this process. Of course, the pixel point of the target area may also be controlled to perform a reciprocating process of moving the second movement amount once in the row direction, a reciprocating process of moving the first movement amount once in the row direction, and a reciprocating process of moving the second movement amount once in the column direction, relative to the home position of the target area, and so on.
According to the screen control method provided by the embodiment of the application, under the condition that the duration of the electronic equipment in an unused state is less than the first duration, after the movement amount is determined based on the resolution and the movement direction of the screen, the pixel points of the target area are controlled to move according to the determined movement amount, so that the movement amount of the target area corresponds to the resolution, the problems of screen aging and screen burning can be solved, and the movement of a picture visible to naked eyes is avoided.
Referring to fig. 10, fig. 10 is a schematic flow chart illustrating a screen control method according to another embodiment of the present application. The screen control method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 10, and the screen control method may specifically include the following steps:
step S310: and acquiring the equipment state data of the electronic equipment under the condition that the screen is in a bright screen state.
Step S320: and if the electronic equipment is determined to be in the unused state based on the equipment state data, acquiring the time length of the electronic equipment in the unused state as the target time length.
Step S330: and if the target duration is less than the first duration, controlling a pixel point of a target area in a display picture of the screen to move, wherein the contrast of the target area is greater than a preset contrast.
In the embodiment of the present application, steps S310 to S320 may refer to the contents of the foregoing embodiments, and are not described herein again.
Step S340: and if the target duration is greater than or equal to the first duration and the target duration is less than a second duration, reducing the display brightness of the screen, wherein the second duration is greater than the first duration.
In the embodiment of the application, after the target duration of the electronic equipment in the unused state is obtained, whether the target duration is less than a first duration or not can be determined; under the condition that the target duration of the electronic equipment in the unused state is greater than or equal to the first duration, whether the target duration is less than the second duration can be further judged; if the target duration is less than the second duration, it indicates that the duration that the user does not use the electronic device is relatively long, but at this time, the user may leave for a short time, and the user may use the electronic device again at any time. In this case, the display luminance of the screen can be reduced, and thus, the aging of the screen pixels and screen burn-in can be further improved. The second duration is longer than the first duration, and the specific value of the second duration may not be limited. It can be understood that after the electronic device is in the unused state, the time length of the electronic device in the unused state does not reach the first time length, the problem of pixel aging and screen burning can be improved by moving the pixel points in the target area, and when the time length of the electronic device in the unused state reaches the first time length and does not reach the second time length, the brightness of the display picture can be reduced, so that the aging of the screen pixels and the screen burning are further improved.
In some embodiments, in the case that the duration of the unused state of the electronic device is greater than or equal to the first duration, and the target duration is less than the second duration, reducing the display brightness of the screen may include: and if the target duration is greater than or equal to the first duration and the target duration is less than a second duration, controlling the display brightness of the screen to gradually decrease along with the increase of the target duration. In this embodiment, in the case where the above target time period reaches the first time period but does not reach the second time period, the display luminance may be controlled to be gradually decreased. Alternatively, the display luminance may be reduced once every set time period (for example, every 2 seconds), and the amount of reduction in luminance may be set in advance.
In some embodiments, in the case that the duration of the unused state of the electronic device is greater than or equal to the first duration, and the target duration is less than the second duration, it may be further determined whether the target duration is greater than a third duration, where the third duration is less than the second duration and greater than the first duration, that is, the third duration is between the first duration and the second duration; if the target duration is less than the third duration, the brightness of the target area can be reduced; and the target duration is greater than or equal to the third duration, and the target duration is less than the second duration, the overall brightness of the display picture can be reduced. It can be understood that, when the display brightness of the screen is reduced under the condition that the target duration reaches the first duration and does not reach the second duration, the brightness of the target area may be reduced first, that is, when the target duration reaches the first duration and does not reach the third duration, the brightness of the target area is reduced; and the target duration reaches the third duration, but under the condition that the target duration does not reach the second duration, the overall brightness of the display picture can be reduced, so that the display brightness of the screen is reduced in stages, and the aging of the pixels of the screen and the screen burning can be better improved.
As a possible implementation manner, when the electronic device decreases the brightness of the target area, the electronic device may also control the brightness of the target area to gradually decrease as the target duration increases; when the electronic equipment reduces the overall brightness of the display picture of the screen, the overall brightness of the display picture can be controlled to be gradually reduced along with the increase of the target duration, so that the brightness reduction can be realized in a gradual change process when the brightness of the target area is reduced and the overall brightness of the display picture is reduced, and the aging of the pixels of the screen and the screen burning are preferably improved.
Step S350: and if the target duration is greater than or equal to the second duration, controlling the screen to be in a turning-off state.
In the embodiment of the application, after the target duration of the electronic equipment in the unused state is obtained, whether the target duration is less than a first duration or not can be determined; under the condition that the target duration of the electronic equipment in the unused state is greater than or equal to the first duration, whether the target duration is less than the second duration can be further judged; if the target duration is greater than or equal to the second duration, the duration that the user does not use the electronic device is very long, the possibility that the user leaves the electronic device for a short time is not high, and the possibility that the screen is in a bright screen state for a long time can be increased. Therefore, in this case, the screen can be controlled to be in the off state, and the power consumption of the electronic device can be reduced while the screen can be better protected.
It can be understood that, while the electronic device is in the bright screen state and in the unused state, the target time length may be constantly counted, and the above steps may be repeated continuously to determine the size relationship between the target time length and the first time length and the second time length, and according to the determination result, different processing may be performed.
According to the screen control method provided by the embodiment of the application, under the condition that the duration of the electronic equipment in an unused state is less than the first duration, the area with higher contrast is controlled to move, the aging of pixels in the area with higher contrast can be distributed to other areas, the aging of pixels of a screen is delayed, the afterimages are improved to a certain extent, and the display effect is improved; when the target duration reaches the first duration but does not reach the second duration, the brightness of the screen is reduced, and when the target duration reaches the second duration, the screen is controlled to be extinguished, so that the display of the screen can be better controlled, and the problems of aging and screen burning of screen pixel points are solved.
