Based on the above hardware structure, an embodiment of the display control method of the present invention is provided.
Referring to fig. 2, fig. 2 is a schematic flowchart of a display control method according to a first embodiment of the present invention, where the method is used in a television, and the method includes the following steps:
step S11: and determining the picture type of the display picture of the television screen.
It should be noted that the main execution body of the present invention is a television, the structure of the television is described above, the television is installed with a display control program, and when the television executes the display control program, the steps of the display control method of the present invention are implemented. The screen of the television is used for displaying (or playing) pictures, generally, when a user watches the television, a picture being displayed by the television is the display picture, and the display picture may be a game picture or a video picture, etc. In the present application, the television is an OLED television.
In addition, in the present application, the type of the displayed picture may be a dynamic picture, a static picture, or a combined dynamic and static picture (a part of the picture is static, and a part of the picture is dynamic).
Specifically, step S11 includes: and when the television is accessed to the signal, determining the picture type of the display picture of the screen. That is, only when the television receives the signal, the television displays the picture corresponding to the signal, and at this time, the type of the display picture of the television needs to be determined.
In addition, when the television does not access a signal, if the operation of the user is not received within a fifth time period, a second screen protection picture is played, wherein the second screen protection picture is a dynamic picture; and entering a standby mode for closing the screen when the operation of the user is not received within a sixth time after the second screen protection picture is played. In a specific application, the fifth time period may be 1 minute, the sixth time period is 8 minutes, and the user may set the corresponding fifth time period and sixth time period based on the requirement, which is not limited in the present invention.
It can be understood that the second screen protection picture is generally a dynamic picture set by a manufacturer for the OLED television set, and is used for protecting the OLED screen of the television set, so that the OLED screen is not prone to afterimage. In the present invention, the second screen protection picture may be a moving screen protection picture such as a dynamic clock and a dynamic scene (e.g., a water drop dynamic picture, a sky dynamic picture, etc.), and the present invention is not limited thereto.
When an OLED television system is designed, the television usually sets a signal identification flag, for example, when no signal is accessed under DTMB/AV/HDMI, the flag bits are: no Signal _ true, the television is started to enter a homepage state or a third-party application interface; when the DTMB/AV/HDMI has an access signal, the flag bit is as follows: no Signal _ false. When the flag bit information acquired after the user is powered on is No Signal _ true, the television detects that the user plays the movable screen saver picture (namely playing the second screen saver picture) in the case of No operation within 1 minute, and the television automatically enters a standby state of closing the screen in the case of No operation within 8 minutes after the movable screen saver picture is played, so that the working time of the OLED television in a No-signal state is reduced, and the OLED television is energy-saving and environment-friendly.
In a specific application, the step of determining the picture type of the screen display picture is as follows:
when the television is accessed to the signal, if the operation of the user is not received within a seventh time period, screenshot is carried out on a display picture of the television to obtain an initial image; when the operation of the user is not received within the eighth time length after the initial image is obtained, screenshot is performed again on the display picture of the television to obtain a reference image; and comparing the reference image with the initial image to determine the picture type. The seventh time length may be 1 minute, and the eighth time length may be five minutes, that is, after the television is turned on, when the flag bit information obtained after the user is turned on is No signal _ false, and the television detects that the user has No operation within 1 minute, the current picture of the television is captured and stored as the initial image; after the initial image is obtained, when the television detects that the user does not operate within 5 minutes, the current television picture is intercepted again to obtain the reference image.
In addition, the step of comparing the reference image with the initial image to determine the picture type specifically includes: obtaining a first self-luminous characteristic of each pixel point in the screen based on the initial image; obtaining a second self-luminous characteristic of each pixel point based on the reference image; comparing the first self-luminous characteristic with the second self-luminous characteristic to determine the number of dynamic pixels of the pixel point with changed self-luminous characteristics in the screen; determining a ratio of the number of dynamic pixels to the total number of pixels in the screen; determining the picture type based on the ratio; when the ratio is greater than or equal to a first ratio, the picture type is a dynamic picture, when the ratio is less than or equal to a second ratio, the picture type is a static picture, when the ratio is between the first ratio and the second ratio, the picture type is a dynamic and static combined picture, and the first ratio is greater than the second ratio.
It can be understood that, the self-luminous characteristics of each pixel point on the screen of the television at the two different moments are determined by analyzing the pixel values of the screenshots of the television at the two different moments, the number of the pixel points (dynamic pixel points) with changed self-luminous characteristics is determined by comparing the self-luminous characteristics of the pixel points in the two screenshots, and the number of the dynamic pixel points is the number of the dynamic pixel points, and meanwhile, the number of the pixel points (static pixel points) with unchanged self-luminous characteristics can also be determined.
In some embodiments, when a certain fixed time period (e.g., 4 minutes) after the second screenshot is reached, a third screenshot may be performed, and the third screenshot and the first screenshot are compared to determine the corresponding screen type.
In a specific application, the first ratio may be 0.5, the second ratio may be 0.2, and the user may set other values based on the requirement, and the two ratios in the present application are preferred choices. The television has different display control strategies for different types of display pictures.
Step S12, when the picture type is a static picture, if the operation of a user is not received within a first time length, the brightness value of the screen is reduced by a first brightness value;
step S13: and playing a first screen protection picture within a second time length after the brightness value of the screen is reduced to the first brightness value and when the operation of a user is not received, wherein the first screen protection picture is a dynamic picture.
In specific applications, the first duration may be 5 minutes, the second duration may be 5 minutes, and the first screen saver picture refers to the description of the second screen saver picture above, which is not described herein again; the first luminance value may be 20% (the luminance values in this application are all expressed in percentage, i.e. the ratio of the adjusted luminance value to the maximum luminance value of the screen). For the static picture, the adjustment of the screen brightness to the first brightness value may be a linear adjustment of the brightness value, so that the user feels that the displayed picture is not abrupt, and the user experience is better.
In addition, in some embodiments, when the user operation is not received within a second time period after the brightness value of the screen is reduced to the first brightness value, and when the user operation is not received within a certain time period (for example, 8 minutes) after the first screen protection picture is played, the television may be controlled to enter a standby state in which the screen is closed, so as to save energy and protect environment.
It is understood that, when the operation of the user is detected after the screen brightness of the television is reduced, the brightness value of the screen may be linearly adjusted to the normal brightness value. Or after the screen of the television is closed, when the operation of the user is detected, the screen can be opened, and the brightness value of the screen is adjusted to the normal brightness value.
In addition, when the picture type is a dynamic picture, if the operation of the user is not received within a third time length, the brightness value of the screen is reduced by a second brightness value. Wherein the third time period may be five minutes and the second brightness value may be 20%. In a specific application, after the step of adjusting the brightness value of the screen to be lower than the second brightness value, when the operation of the user is not received within a certain time period (for example, five minutes), the brightness value is continuously adjusted to be lower by 20%.
In some embodiments, when the picture type is a dynamic and static combined picture, a dynamic area and a static area are determined in the screen; adjusting the brightness value of the static area to be lower than a third brightness value, and adjusting the brightness value of the dynamic area to be lower than a fourth brightness value; and in a fourth time period after the brightness value of the dynamic area is reduced to the fourth brightness value, when the operation of the user is not received, reducing the brightness value of the static area to a fifth brightness value, and reducing the brightness value of the dynamic area to a sixth brightness value.
It can be understood that the dynamic area is an area corresponding to the above dynamic pixel point, and the static area is an area corresponding to the above static pixel point; the third brightness value and the fifth brightness value may be 30%, the fourth brightness value and the sixth brightness value may be 20%, and the user may set other values based on the requirement.
In other embodiments, when the picture type is a dynamic and static combined picture, a dynamic area and a static area are determined in the screen; after the brightness value of the static area is reduced to the third brightness value and the brightness value of the dynamic area is reduced to the fourth brightness value, within a certain time (for example, five minutes), the operation of the user is not received, the first screen protection picture can be played, and within a certain time (for example, 10 minutes) after the first screen protection picture is played, the operation of the user is not received, and then the standby mode of closing the screen is entered.
It can be understood that, in many cases of the present invention, within a certain time period after the television enters the state of playing the first screen protection picture, the television still can enter the standby mode of turning off the screen when not receiving the operation of the user, so as to save electric energy and protect the environment.
The technical scheme of the invention provides a display control method for a television, which comprises the following steps: determining the picture type of a display picture of the television screen; when the picture type is a static picture, if the operation of a user is not received within a first time length, the brightness value of the screen is reduced by a first brightness value; and within a second time period after the brightness value of the screen is reduced to the first brightness value and when the operation of the user is not received, playing a first screen protection picture, wherein the first screen protection picture is a dynamic picture.
If the display image of the television is a static image and the television displays the static image with high brightness for a long time, the aging speed of the screen of the television is accelerated, and the screen has afterimages. By adopting the display control method, when the display picture of the television is the static picture, the brightness is firstly adjusted to be low, and when the user operation is not received within the second time period, the first screen protection picture is played, so that the static picture with high brightness value is prevented from being displayed on the screen for a long time, the aging speed of the screen of the television is reduced, the picture cannot have ghost shadow when the screen of the television displays the picture, and the user experience is improved.
