Abstract

The embodiment of the invention discloses a display device and a driving method thereof, and electronic equipment. The driving method of the display device comprises the following steps: determining adark display area and a bright display area of a display function area according to a picture to be displayed of a display panel, wherein the dark display area comprises a black display area and a boundary display area, and the boundary display area is located between the black display area and the bright display area; and when the display panel displays the picture to be displayed, controlling apixel gray scale value of the boundary display area to be greater than 0 and less than a pixel gray scale average value of the bright display area adjacent to the boundary display area, and adjustingthe backlight brightness La corresponding to the boundary display area, wherein La is greater than 0 but less than Lb, and Lb is the backlight brightness of a backlight partition corresponding to thebright display area adjacent to the boundary display area. According to the driving method of the display device provided by the embodiment of the invention, the boundary display area serves as the brightness transition of the bright display area and the black display area, so that the bright and dark display areas gradually become dark, so that the display transition of the display picture is soft, good visual effect is achieved, and the display power consumption is not greatly increased.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device, a driving method thereof, and electronic equipment. Background technique [0002] High-Dynamic Range images (High-Dynamic Range, referred to as HDR), compared with ordinary images, can provide more dynamic range and image details, according to different exposure times of low-dynamic range images (Low-Dynamic Range, referred to as LDR) , use the LDR image corresponding to the best details of each exposure time to synthesize the final HDR image, which can better reflect the visual effect in the real environment. The HDR display has higher color depth, wider dynamic range and stronger color expression. The specific HDR display uses a display panel with a high NTSC color gamut and a backlight module with local dimming to achieve image quality. High color gamut and high contrast. [0003] When the existing HDR algorithm displays a picture with many...
