Problems solved by technology

[0003] However, the difference in brightness in areas with low grayscale (for example, below grayscale 10) is very obvious. When the moiré phenomenon is serious, the compensation value used is relatively large. In this case, the dev

Abstract

The invention discloses a liquid crystal driving system. The liquid crystal driving system comprises a sequence controller and a memory storage device, the sequence controller is used for reading a gray-scale compensation value in the memory storage device and obtaining a correction gray-scale value according to the gray-scale compensation value and an initial gray-scale value from a host system, the sequence controller comprises a gray-scale detection circuit and a gray-scale compensation operation circuit, the gray-scale detection circuit is used for detecting whether the initial gray-scale value of the host system is smaller than or equal to a fixed value, and the sequence controller regards the initial gray-scale value as the correction gray-scale value when the initial gray-scale value is smaller than or equal to the fixed value. According to the liquid crystal display driving system, the phenomenon of non-uniform display brightness caused by low gray-scale compensation of a liquid crystal display panel can be avoided. The invention also discloses a liquid crystal driving method.
