Abstract

The embodiment of the invention discloses a display method and a display device. The display method comprises the steps of obtaining a to-be-displayed image; Extracting a contour bright line of the to-be-displayed image, and obtaining a gray scale peak value Y1 of the contour bright line; Judging whether the gray scale peak value Y1 is smaller than a preset gray scale value Y0 or not; If yes, thegray scale peak value Y1 is increased, and gray scale values of other sub-pixels of the contour bright line in the display panel are increased; And the output brightness of the backlight subarea corresponding to the contour bright line is reduced. According to the display method provided by the embodiment of the invention, the display contrast can be improved, and meanwhile, halo can be reduced.

Description

technical field [0001] The present invention relates to display technology, in particular to a display method and a display device. Background technique [0002] Dynamic Range (Dynamic Range, DR) broadly refers to the span range that can be changed by a certain change transaction. For a static image or video frame, the dynamic range is the range from the darkest tone to the brightest color, and the light and dark changes are realized within this range; the range The larger the value is, the more layers of light and shade changes in the image, and the stronger the ability of the display device to describe the details of the image. The traditional liquid crystal display (Liquid Crystal Display, LCD) adopts global backlight, and its dynamic range is about 2 orders of magnitude, and the global backlight also has relatively serious light leakage phenomenon, which is one of the reasons for limiting the display contrast of LCD. [0003] At present, in order to solve this problem, ...
