Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of 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, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In order to solve the problem that the service life of the display device is affected by the high refresh rate of the display device in the related art, the embodiment of the present application provides a screen refresh rate control method, as shown in fig. 1, which is a basic flowchart of the screen refresh rate control method provided in the present embodiment, where the screen refresh rate control method includes the following steps:
step 110, obtaining a screen display requirement of a current application scene of a display screen.
In particular, in practical application, the main application scene of the high refresh rate is electronic competition or daily game, and the advantage of the high refresh rate can be highlighted only in game pictures, and in daily use, as the pictures are basically switched without long continuity, the perception of the high refresh rate in daily use is not so strong. In this embodiment, the screen display requirements include, but are not limited to, requirements for screen display features, including, but not limited to, video definition and smoothness of a screen, the screen display requirements are obtained according to the current application scene of the display screen, and the screen display requirements of different application scenes are different. For example, when the same type of display screen is applied to an electronic competition, the requirements of video definition and picture smoothness are very high, otherwise the competition experience and competition state of contestants are affected, and when the display screen is applied to daily entertainment games, even when requirements such as web browsing or document writing are met, the requirements of video definition and picture smoothness are far lower than those of electronic competition. Therefore, it would be advantageous to provide a system that controls the screen refresh rate by acquiring the screen display requirements of the current application scenario of the display screen before controlling the screen refresh rate.
In an optional implementation manner of this embodiment, the step of obtaining a screen display requirement of a current application scene of a display screen includes: detecting the current display content of a display screen; determining an application scene of a display screen according to the display content; and acquiring corresponding screen display requirements according to the application scene.
Specifically, in practical application, before the electronic competition begins, a worker can debug the computer to determine whether various parameters of the host computer and the display screen are problematic, and after the game is entered in advance, whether a plug-in or an illegal script exists on the computer is monitored through an installed safety monitoring system, that is, the electronic competition computer has more strict configuration and a corresponding detection system exists. In this embodiment, the current display content of the display screen is determined by detecting the current display content of the display screen, and whether the current display screen is a game scene with a high refresh rate requirement or a scene such as web browsing or document writing with a low refresh rate requirement is determined according to the display content, and then the corresponding video definition and picture smoothness are obtained according to the application scene, where the video definition and picture smoothness of the same display screen in different application scenes are different.
And 120, dividing a screen display area according to the screen display requirement.
Specifically, a liquid crystal display screen can be divided into three parts according to different functions: a display area, a sealing area and a gasket area. The display area refers to the image display area of a display screen, and is an array of pixels. Typically one pixel is again made up of three sub-pixels, red, green and blue. The array has column pixels (H) distributed in the horizontal direction and row pixels (V) distributed in the vertical direction. For example, a full-high-definition liquid crystal display is composed of 1920 columns in the horizontal direction and 1080 rows in the vertical direction, and is generally expressed as h×v=1920×1080 pixels, or h×v=1920× (3) ×1080 sub-pixels. In this embodiment, the display area is further divided into a plurality of different screen display areas according to the requirements for the screen display characteristics in different application scenarios. When multiple application programs are required to be operated simultaneously in the display area, the screen display requirements among the different application programs are different, for example, when three kinds of screen splitting operation is performed on a reading website, a movie and a game, the screen display characteristics of the reading website obviously cannot meet the requirements of the movie and the game on the screen display characteristics, and the screen display characteristics of the game are excessively wasted when being applied to the reading website, so that the display area can be divided into three screen display areas according to the different requirements of the three kinds of screen display characteristics after the screen splitting operation. It should be noted that, the screen splitting only divides the display area into different areas for operation, and the screen display characteristics such as the smoothness of the images after splitting are consistent, which is different from the embodiment that divides the display area into a plurality of screen display areas according to the screen display requirement, and each screen display area can independently adjust the refresh rate according to the screen display requirement.
In an optional implementation manner of this embodiment, the step of dividing the screen display area according to the screen display requirement includes: dividing the display screen into a plurality of unit screen display areas according to screen display requirements based on unit pixels of the display screen; or dividing the display screen into a plurality of array screen display areas according to the screen display requirements based on the pixel array of the display screen; the pixel array is an array formed by a plurality of unit pixels.
Specifically, in practical applications, for example, the display area of the above-mentioned full-high-definition liquid crystal display may be understood as a pixel array composed of pixels, and the display area may be understood as a largest pixel array, and one pixel point used for composing the pixel array is a unit pixel, and different pixel arrays are formed by combining different unit pixels, in this embodiment, according to the display requirements of different screen display features, all pixel points on the display screen may be divided into unit screen display areas based on the unit pixels of the display screen; or the pixel points are formed into pixel arrays with random sizes according to actual demands, and then the display screen is divided into a plurality of array screen display areas according to different pixel arrays. For example, the screen display requirement of the reading website is low, so that the display screen can be divided into a plurality of array screen display areas according to the pixel array, and the screen display requirement of the competitive game is high, so that the display screen needs to be divided into unit screen display areas according to unit pixels, and the high requirement of the competitive game on the screen display characteristics is met.
And 130, controlling different screen display areas to refresh the display screen at different screen refresh rates.
In particular, in practical applications, for example, the refresh rate of the electronic contest display generally needs to be at least 144hz, but as a display with a high refresh rate, a large power consumption is necessarily caused according to the highest refresh rate for a long time, so that the service life of the electronic contest display is affected. In this embodiment, after dividing the screen display area, the system controls different screen display areas to refresh the display screen at different screen refresh rates according to different screen display requirements, so that the power consumption of the display can be reduced, and the service life of the display screen can be prolonged.
In an alternative implementation of the present embodiment, the step of controlling different screen display areas to refresh the display screen at different screen refresh rates includes: determining a user region of interest in the screen display region; determining a standard screen refresh rate and a preset screen refresh rate according to screen display requirements; and refreshing the display screen of the user region of interest according to the standard screen refresh rate, and refreshing the display screen of the non-user region of interest according to the preset screen refresh rate.
Specifically, in an application scenario where a user plays a game, in a game of a sports type, the user needs to stare at a display screen with a focus, and the gaze always gathers in a certain area and moves, but does not diverge to the whole screen. Thus, in this embodiment, the area where the eyes are focused is set as the user-interested area, and the system can determine the user-interested area within the screen display area by detecting the user's eyes. The standard screen refresh rate and the preset screen refresh rate are determined according to the screen display requirement of the current application scene of the display screen, for example, the factory-set refresh rate of the display screen is 240Hz, the standard screen refresh rate can be set to 240Hz, the preset screen refresh rate can be set according to the lowest refresh standard of the application scene, when the application scene is a competitive game, the preset screen refresh rate is not lower than 144Hz, otherwise, the user operation is seriously affected, and when the application scene is a reading website, the preset screen refresh rate can be set to 60Hzh or 30Hz because the requirement of the reading website on the screen refresh rate is not high. And then, refreshing the display screen of the region of interest of the user according to the standard screen refreshing rate and refreshing the display screen of the region of interest of the non-user according to the preset screen refreshing rate, thereby effectively reducing the power consumption of the display, prolonging the service life, achieving an effect similar to focusing and improving the concentration of the user by reducing the screen refreshing rate of the region of non-interest.
Optionally, the step of determining the region of interest of the user includes: acquiring iris angle change values of a user by projecting the sensing light velocity outwards on a display screen; and determining the region of interest of the user according to the iris angle change value.
Specifically, the sensing beam includes, but is not limited to, an infrared beam. When a person's eyes look in different directions, there are small changes in the eyes that produce extractable features that a computer can extract by image capture or scanning to track changes in the eyes in real time. In this embodiment, first, infrared light is projected outwards on a display screen, and human eyes are irradiated with infrared light, when the user's attention line of sight to the display screen changes, an iris angle change value is determined according to infrared light reflected back by the iris, and a region of interest after the change of the iris angle of the user is determined.
In an optional implementation manner of this embodiment, after the step of dividing the screen display area according to the screen display requirement, the method further includes: acquiring a next frame image of a current display image of a display screen; determining a refreshing area of a screen display area by comparing a current display image with a next frame image; the refresh area is refreshed according to a standard screen refresh rate.
Specifically, in consideration of the fact that in the process of electronic competition, the screen refresh rate of the used electronic competition device is far higher than that of a common display screen, if the highest screen refresh rate is kept for a long time in the environment of high strength and high refresh of the electronic competition, the service life of the electronic competition device is easily influenced. But if the screen refresh rate is reduced for longer life, it will have an effect on the status of the player. In this embodiment, a screen refresh mode of a unit screen display area is adopted, a current display image and a next frame display image of a display screen are firstly obtained, the current display image and the next frame display image are compared, the unit screen display area which changes is determined according to the comparison result, the corresponding unit screen display area is refreshed according to a standard screen refresh rate for the unit screen display area which changes, and the unit screen display area which does not occur in the comparison of the contents of the two frames before and after is not refreshed. And only the changed unit screen display area is refreshed through the change of the front frame and the rear frame, and the service life of the electronic competition device is prolonged on the premise that the competition state of the player is not influenced.
In an optional implementation manner of this embodiment, after the step of controlling the different screen display areas to refresh the display screen at the different screen refresh rates, the method further includes: acquiring the duration time for refreshing the display screen at different screen refreshing rates; and if the duration exceeds the preset duration threshold, adjusting the different screen refresh rates to be standard screen refresh rates.
In particular, in the present embodiment, it is considered that when the display screen is refreshed with different screen refresh rates for a long time, although a high refresh rate is not easily perceived by a player, eye fatigue is extremely easily generated even when the display screen is watched for a long time at different refresh rates. Therefore, the duration of refreshing the display screen at different screen refresh rates is obtained, and if the duration exceeds the preset duration threshold, the different screen refresh rates are adjusted to the standard screen refresh rate. And the screen refresh rate is recalled, so that eye fatigue of the user is effectively relieved.
Based on the embodiment scheme of the application, the screen display requirement of the current application scene of the display screen is acquired; dividing a plurality of screen display areas according to screen display requirements; and controlling different screen display areas to refresh the display screen at different screen refresh rates. Through implementation of the scheme, the display areas of the screen are divided according to the application scene of the display screen, and different display areas refresh the display screen according to different screen refresh rates, so that the power consumption of the display screen can be reduced, and the service life of the display screen is prolonged.
