Method and apparatus for optimizing color cast of WRGB panel and readable storage medium

Abstract

The invention discloses a method and apparatus for optimizing color cast of a WRGB panel and a readable storage medium. The method comprises the following steps: obtaining RGB component information ofcolored image display of a video signal on the WRGB panel and color matching ratios of R, G and B colors of the WRGB panel; enhancing the R component and the B component in the RGB component information according to the color matching ratios to obtain an enhanced R enhancement component and an enhanced B enhancement component; and performing conversion processing on the obtained R enhancement component, the B enhancement component and a G component to obtain a WRGB signal, and outputting the WRGB signal. By enhancing the R component and the B component, the proportion of the G with relativelyweight in the color matching ratios of the R, G and B colors of the WRGB panel, the color cast is eliminated from the color image displayed by the WRGB panel, and by enhancing the R component and theB component, the brightness of the color image displayed by the WRGB panel is enhanced, and the problem that color cast, darkness and other situations to affect the image quality performance when a part of colors is displayed in the WRGB panel is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method and device for realizing color cast optimization of a WRGB panel, and a computer-readable storage medium. Background technique [0002] Using an RGB (full name Red, Green, Blue, Chinese name red, green and blue) panel as a display panel is a common technical means in liquid crystal display technology. Since the RGB panel can only achieve 100% transmittance when the three color sub-pixels of RGB are all turned on, and the display principle of the WRGB panel is to change the composition of each sub-pixel, due to the addition of white sub-pixels (W sub-pixels), As long as the W sub-pixel is turned on, the transmittance of the panel is 100%, which improves the transmittance of the panel. [0003] Due to the addition of W sub-pixels in the WRGB panel, the proportion of R / G / B in the white field decreases, so the Y value of the color coordinates of the image dis...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above method that because the proportion of G in the R / G / B ratio of the WRGB panel is relatively large, the color displayed on the WRGB panel by mixing G sub-pixels will be greenish

In addition, due to the addition of W sub-pixels in the WRGB panel, when the white field brightness is the same as that of the RGB panel, the color brightness is darker.

There is a technical problem that when some colors are displayed on the WRGB panel, there will be color casts, darkening, etc., which will affect the performance of the image quality.
