Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a screen display control method, apparatus, electronic device, and medium. Background Art

[0002] For a terminal device using an LCD display screen, when the display screen displays a certain static image for a long time, there is a high probability that afterimages will be left, which is called screen polarization. Slight screen polarization can recover by itself after waiting for a long time, but severe screen polarization is irreversible, thus affecting the service life of the display screen.

[0003] Currently, the commonly used polarization elimination solutions mainly include two types: hardware elimination and software elimination. Among them, hardware elimination can eliminate polarization by providing a correction voltage to correct the deflection angle of liquid crystal molecules, while the software solution generally eliminates polarization by setting a dynamic screensaver wallpaper. However, for these two solutions, hardware elimination requires the screen to have corresponding hardware circuits, and the dynamic screensaver wallpaper completely blocks the current display screen, affecting the normal viewing of the display screen by users in some cases.

[0039] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0040] Please refer to Figure 1 , the first embodiment of the present invention provides a screen display control method, which can be executed by an electronic device, and particularly, by one or more processors in the electronic device, to implement the following steps:

[0041] S101, obtain the current display state of the screen.

[0042] In this embodiment, the electronic device is an electronic device with an LCD screen, such as a smart phone, a tablet, a desktop computer, a laptop computer, etc., and this embodiment does not make specific limitations.

[0043] Among them, in this embodiment, the electronic device can receive the data to be displayed and display these data through the screen, thereby forming a corresponding display screen.

[0044] S102. When it is determined that there is a static area on the screen where the display state remains unchanged for more than the static time, change the display state of the screen so that the display state of each pixel in the static area changes at least once within a set time.

[0045] In this embodiment, when the user does not operate the electronic device, part or all of the display screen of the screen may remain unchanged for a long time. Among them, when part of the display screen remains unchanged for a long time, the screen will include two parts: a static area and a dynamic area. When all of the display screen remains unchanged for a long time, all areas of the screen are static areas. In either case, as long as there is a long-term static area, it may cause polarization of the screen.

[0046] Therefore, in this embodiment, when it is determined that there is a static area on the screen where the display state remains unchanged for more than the static time, the electronic device will change the display state of the screen so that the display state of each pixel in the static area changes at least once within a set time. Among them, the static time can be set by the user or can be the default value set by the electronic device, and the present invention does not make specific limitations.

[0047] In a specific implementation manner, when the static area is the entire display area of the screen, briefly change the display state of each pixel within a set time.

[0048] Among them, by briefly changing the display state of each pixel, on the one hand, it can avoid screen polarization caused by the display screen remaining unchanged for a long time, and on the other hand, the display state of the pixel only changes briefly and will not affect the user's viewing of the display screen.

[0049] For example, as Figure 2 shown, when the static area is the entire display area of the screen, a scanning color block 10 can be generated, and then the screen is scanned at least once with the scanning color block 10, so that the display state of each pixel on the screen changes when it is scanned by the scanning color block 10.

[0050] Among them, particularly, the length of the scanning color block can be set to the display length or the display width of the screen. In this way, the color block can be moved up and down or left and right to scan the screen. During the scanning process, the color values of the pixel points in the area covered by the scanned color block will be briefly displayed as the color of the scanning color block, and then return to their original colors after the scanning color block passes. In this way, each pixel point on the screen will have a brief change during each scan, avoiding the screen polarization problem caused by the display screen remaining unchanged for a long time.

[0051] Among them, particularly, the colors of the pixel points of the scanning color block should cover as many different colors as possible, and the transparency of the pixel points on the scanning color block is set to semi-transparent or highly transparent. In this way, the influence of the scanning color block on the user's viewing of the display screen during the scanning process can be reduced.

[0052] Among them, particularly, in this embodiment, the scanning speed, scanning period, and scanning times of the scanning color block can all be set according to actual needs. For example, it can be scanned once every 5 minutes or scanned twice every 8 minutes, etc. The present invention does not make specific limitations.

[0053] In another specific implementation manner, when the static area is a partial area of the screen, step S102 specifically includes:

[0054] Obtain the static area and the dynamic area where the display state changes;

[0055] Cover the screen with a global background image, and set the display level of the dynamic area above the global background image.

[0056] In this embodiment, for example, when the user watches a video in a non-full-screen state, the video playback area is dynamic and other areas are static. For another example, as shown in Figure 3 and Figure 4 , in a timing interface, only the area where the timer is located is the dynamic area and other areas are static. In this case, the user usually focuses on the content of the dynamic area 20.

[0057] Therefore, in this embodiment, as shown in Figure 4 , the electronic device can use a global background image to cover the screen and set the display level of the dynamic area 20 above the global background image. In this way, while not affecting the user's viewing of the content of the dynamic area 20, the display state of the static area can be changed, thus avoiding the screen polarization of the static area.

[0058] Among them, particularly, the global background image is composed of dark pixel points. In this way, the screen polarization can be better reduced.

[0059] Among them, particularly, bright pixels 30 that can move dynamically can also be scattered on the global background image, so that the display state of the pixels in the static area can be changed irregularly, further reducing screen polarization.

[0060] Among them, particularly, the global background image can exist for a long time. For example, as long as the user does not operate the electronic device, the global background image will always exist. The global background image can also exist briefly. For example, it will automatically disappear after a predetermined time and then reappear after a static time. These solutions are all within the protection scope of the present invention.

[0061] In addition, it should be noted that for the case where there are local static areas and local dynamic areas, the method of scanning color blocks can also be used to avoid screen polarization. These solutions are all within the protection scope of the present invention.

[0062] In this embodiment, when the electronic device detects the user's operation, it automatically returns to the normal working state.

[0063] In summary, in this embodiment, when it is detected that the display state of some areas on the screen has not changed for a long time, the display state of the pixels in these areas is actively changed, thereby avoiding the generation of screen polarization, and this embodiment can minimize the normal viewing of the screen by the user.

[0064] Please refer to Figure 5 , a second embodiment of the present invention provides a screen display control device, which includes:

[0065] A display state acquisition unit 210, configured to acquire the current display state of the screen;

[0066] A display state change unit 220, configured to change the display state of the screen when it is determined that there is a static area on the screen where the display state remains unchanged for more than the static time, so that the display state of each pixel in the static area changes at least once within a set time.

[0067] A third embodiment of the present invention further provides an electronic device, which includes:

[0068] At least one processor; and,

[0069] A memory communicatively connected to the at least one processor; wherein,

[0070] The memory stores instructions executable by the at least one processor, and when the instructions are executed by the at least one processor, the at least one processor can execute the screen display control method of any of the foregoing embodiments.

[0071] The fourth embodiment of the present invention further provides a non-transitory computer-readable storage medium, which stores computer instructions for causing the computer to execute the screen display control method of any of the foregoing embodiments.

[0072] The fifth embodiment of the present invention further provides a computer program product, which includes a computing program stored on a non-transitory computer-readable storage medium. The computer program includes program instructions that, when executed by a computer, cause the computer to execute the screen display control method of any of the foregoing embodiments.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present disclosure should be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
