With the continuous development of liquid crystal display, the demand for high-performance liquid crystal display is more and more urgent. Many researchers had also carried out a series of researches on improving the performance of liquid crystal display. The color performance, which can be indicated by Gamma shift and color shift, is an important aspect of LCD performance. This paper summarizes the color performance of the conventional three LCD modes, and mainly introduces the improved methods of in-plane switching and vertical aligned LCD modes. It has an important significance to the researchers and designer of LCD. For different display modes, there are corresponding methods to improve the color performance, but each method has its own inherent flaws, it requires users to choose.
