Abstract

The embodiment of the invention discloses a display device, a driving method thereof and an electronic device. The display device comprises a backlight module and a display panel. The display panel comprises a display area. The display area comprises a plurality of pixels, each pixel at least comprises a first color sub-pixel, and the display area comprises a first display area and an edge displayarea surrounding the first display area. The driving method comprises the steps of receiving a to-be-displayed image and obtaining an input gray scale P1i of each first color sub-pixel located in anedge display area in the to-be-displayed image; according to the brightness offset parameter and the input gray scale P1i of the first color sub-pixel, adjusting the output gray scale P1o of the firstcolor sub-pixel according to the following formula, k being a color offset degree value, and the brightness offset parameter being smaller than 1. In the embodiment of the invention, the phenomenon of darkening of the edge display area in the display stage is improved, and the display effect is optimized.

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] The HDR display is equipped with miniature light-emitting di...
