Title:
COLOR TEMPERATURE ADJUSTING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/150161
Kind Code:
A1
Abstract:
Disclosed are a color temperature adjusting method and device, which relate to the technical field of display. The method comprises: obtaining a chromaticity coordinate value of a pixel in a liquid crystal screen when the liquid crystal screen displays a white image(101); detecting whether the chromaticity coordinate value is in a target chromaticity coordinate region or not, wherein the target chromaticity coordinate region is a region including the target chromaticity coordinate value, and the target chromaticity coordinate value is a chromaticity coordinate value obtained through calculation according to the target color temperature of the liquid crystal screen (102); and if the chromaticity coordinate value is not in the target chromaticity coordinate region, adjusting a component value of at least one kind of primary light in N kinds of primary light corresponding to the pixel, and stopping the adjustment until the chromaticity coordinate value of the pixel is in the target chromaticity coordinate region after the adjustment, where N is a positive integer (103). The method solves the problem of color temperature inconsistency of a liquid crystal screen even if LEDs in different blocks are arranged on the liquid crystal screen in a crossing way, thereby achieving the effect of improving the color temperature consistency of the liquid crystal screen.
