Abstract

The invention discloses a method for improving the skin color cast of a liquid crystal display panel, comprising: acquiring a proportion value of a skin color area in a frame to be displayed by the liquid crystal display panel; and comparing the proportion value of the skin color area with a predetermined value; If the proportion of the skin color area is greater than the predetermined value, then use the first gamma value to perform gamma correction on the red data, green data and blue data in the one frame; wherein, the first gamma value A gamma value greater than 2.2. The invention also discloses a system for improving the color deviation of the skin color of the liquid crystal display panel. The present invention increases the gamma value of the front viewing angle picture of the liquid crystal display panel; correspondingly, the gamma value of the large viewing angle picture of the liquid crystal display panel is closer to the curve with a gamma value of 2.2, thereby eliminating the large viewing angle picture of the liquid crystal display panel The skin color appears white (Wash Out) phenomenon.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a method and system for improving the skin color cast of a liquid crystal display panel. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat panel displays. Among many flat panel displays, liquid crystal displays (LCD for short) have high space utilization efficiency and low power consumption. , no radiation and low electromagnetic interference and many other superior features have become the mainstream of the market. [0003] Among various display modes of liquid crystal displays, a vertical alignment (Vertical Alignment, VA) display mode is popular in the market due to its good viewing angle characteristics. In the LCD of the VA display mode, the long axis of the liquid crystal molecules in the pixel unit is perpendicular to the filter in the state of no...
