Embodiment 1

[0047] This embodiment provides a display screen processing circuit, the display screen is divided into multiple display areas, the processing circuit includes a plurality of display control units corresponding to the multiple display areas, each display control unit Output image data to the corresponding display area, such as figure 1 As shown, this embodiment includes:

[0048] The line-of-sight capture module 11 is used to perform eye tracking of the human eye, and obtain the attention area where the line of sight of the human eye falls on the display screen;

[0049] A control module 12, configured to determine a first display area that overlaps with the attention area among the plurality of display areas and a second display area other than the first display area, and control The display control unit corresponding to the area outputs the first image data, and controls the display control unit corresponding to the second display area to output the second image data, and t...

Embodiment 2

[0063] This embodiment provides a display device, including a display screen and the above-mentioned processing circuit of the display screen. Such as Figure 4 As shown, the display screen is divided into a plurality of display areas, and the processing circuit includes a plurality of display control units corresponding to the plurality of display areas, each display control unit outputs image data to the corresponding display area, and by judging The human eye falls on the focus area on the display screen, and the refresh rate of the display screen is adjusted by area, so that the refresh rate of the focus area on the display screen is higher than that of other areas, such as controlling the display area A The refresh frequency of the display area B is higher than that of the display area B, which can ensure the display quality of the display screen in the area of ​​interest, without affecting the viewing experience of the user, and can reduce the data processing amount of t...

Embodiment 3

[0068] This embodiment provides a display method for a display screen, which is applied to the above-mentioned display screen, such as Figure 6 As shown, the display method includes:

[0069] Step 601: Carry out eye tracking of human eyes, and obtain the attention area where human eyes fall on the display screen;

[0070] Step 602: Determine a first display area that overlaps with the attention area among multiple display areas of the display screen and a second display area other than the first display area, and control The display control unit corresponding to the area outputs the first image data, and controls the display control unit corresponding to the second display area to output the second image data, and the refresh frequency of the first image data is higher than that of the second image data.

[0071] In this embodiment, by judging the area of ​​interest on the display screen where the human line of sight falls, the refresh rate of the display screen is adjusted ...

Abstract

The invention provides a processing circuit of a display screen, a display method and a display device, and belongs to the technical field of display. The display screen is divided into a plurality of display areas; the processing circuit comprises a plurality of display control units which correspond to the display areas; the processing circuit comprises a sight line capture module and a control module, wherein the sight line capture module is used for conducting eyeball tracking on human eyes so as to acquire a focusing area, on the display screen, of a sight line of the human eyes; the control module is used for determining a first display area which shares an overlapped area with the focusing area and a second display area out of the first display area, controlling the display control unit, which corresponds to the first display area, to output first image data and controlling the display control unit, which corresponds to the second display area, to output second image data, wherein the first image data is greater than the second image data in refresh rate. According to the technical scheme provided by the invention, the display quality of displayed pictures can be guaranteed, and meanwhile, power consumption of the display device can be reduced and conflict between the high-quality pictures of the display device and low power consumption can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a processing circuit of a display screen, a display method and a display device. Background technique [0002] With the advancement of display technology, users have higher and higher requirements on the picture quality displayed by display devices. Generally, the higher the picture quality of the display device (that is, the clearer the picture), the higher the screen refresh rate. However, a high screen refresh rate will inevitably occupy a large amount of processing resources of the display device, which will greatly increase the power consumption of the display device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing circuit, a display method and a display device of a display screen, which can reduce the power consumption of the display device while ensuring the display quality of the display screen,...
