Abstract

The invention discloses an improving method for skin color bias of a liquid crystal display panel. The improving method includes acquiring a ratio value of a skin color region of a frame to be displayed on the liquid crystal display panel; comparing the ratio value of the skin color region with a preset value; if the ratio value is greater than the preset value, subjecting red data, green data and blue data of the frame to gamma correction with a first gamma value larger than 2.2. The invention further discloses an improving system for the skin color bias of the liquid crystal display panel. According to the arrangement, gamma value of the front viewing angle frame of the liquid crystal display panel is increased, and the gamma value of the large viewing angle frame of the liquid crystal display panel is closer to a curve with the gamma value of 2.2, so that wash out problem of the skin color of the large viewing angle frame of the liquid crystal display panel is eliminated.

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...
