Abstract

The present invention relates to the technical field of display, and provides an edge-type backlight module, a display module and a backlight regulation method. Features of liquid crystal are employedto respectively load voltage signals at two sides of a liquid crystal layer, optical axes of liquid crystal molecules are rotated through voltage amplitude difference to change the transmittance of the liquid crystal layer so as to achieve regulation of backlight brightness of different areas with no need for changing light sources, achieve area light regulation, improve the contrast of display images and improve the visual effect of the display images.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an edge-type backlight module, a display module and a backlight adjustment method. Background technique [0002] Since the display device equipped with HDR (High-Dynamic Range, high dynamic range image) technology displays the closest image to the image observed by the human eye, as the human eye's demand for image display effect continues to increase, HDR technology has become a a trend. HDR is a technology that requires both hardware support and software support. From the hardware level, the current HDR-supporting monitors include monitors with a resolution of 4K supporting HDR, monitors with a resolution of 2K supporting HDR, and monitors with a resolution of 1080P supporting HDR. By adjusting the display brightness of the monitor, the contrast between the darkest area and the brightest area in the image is enhanced to enrich the layers in the image. [0003] In the thin f...
