Abstract

The invention discloses a liquid crystal display device, comprising a panel, a grid driving module and a control module; the control module comprises a driving module, a data processing module and a correction circuit; the data processing module comprises a first lockup table, a second lookup table and a compensation module; the first lookup table comprises a plurality of first compensation coefficients corresponding to a plurality of display areas; the second lookup table comprises a plurality of second compensation coefficients corresponding to a plurality of gray scale values of an original grid signal; the compensation module is used for performing compensation on the corrected grid signal according to the corresponding the plurality of first compensation coefficients and the plurality of the second compensation coefficients to generate compensation grid signals.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a grid signal compensation method. 【Background technique】 [0002] Liquid crystal display devices have been rapidly developed due to their small size, light weight, low power consumption, and excellent display quality. With the development of economy and technology and the improvement of people's quality of life, people's requirements for liquid crystal display devices are getting higher and higher. Manufacturers pay attention to large size, high resolution, ultra-narrow bezel, and ultra-thin. [0003] As the size of the liquid crystal display device becomes larger and the frame becomes narrower, the gate signal line on the liquid crystal display device will become thinner and its impedance will become larger and larger. The impedance of the gate signal line The increase will affect the uniformity of the image, and some bad pr...
