Display device and driving method thereof and electronic equipment

Abstract

The embodiment of the invention discloses a display device and a driving method thereof and electronic equipment. The display device comprises a display panel and a backlight module; the display panelcomprises a display function region; the display function region comprises a plurality of pixels; the backlight module comprises a plurality of backlight units; one backlight unit is arranged corresponding to at least one pixel; and the driving method comprises the steps of: according to a to-be-display image of the display panel, acquiring input parameters Ri, Gi and Bi of each pixel in the display panel; and according to a power consumption saving gear n of the display panel and the input parameters of each pixel, determining an amplification coefficient alpha=function (min, max, n) of eachpixel in the display panel so as to regulate output parameters of the pixels, and regulating backlight brightness of the backlight units corresponding to the pixels, wherein min=min (Ri, Gi, Bi), andmax=max (Ri, Gi, Bi). According to the embodiment of the invention, display power consumption can be reduced.

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.

AI Technical Summary

Problems solved by technology

[0003] The current HDR algorithm will have different power consumption when displaying different pictures. The power consumption of pictures with more dark areas is relatively small, but when the pictures with more bright areas are displayed, the power consumption will rise rapidly. Limits the application of HDR technology on mobile terminals
