The invention provides a driving circuit and a liquid crystal display device. The driving circuit comprises a time sequence control chip, and is characterized in that the time sequence control chip is used for providing control signals for a programmable gamma correction buffer chip and providing digital signals for a source driving chip; the programmable gamma correction buffer chip is used for outputting first reference voltage to the source driving chip according to the control signals when the time sequence control chip outputs digital signals of a 3nth row of pixels and (3n+1)th row of pixels, and outputting second reference voltage to the source driving chip when the time sequence control chip outputs digital signals of a (3n+2)th row of pixels; and the source driving chip is used for receiving the first reference voltage, the second reference voltage and the digital signals, and generating data voltage according to the first reference voltage, the second reference voltage and the digital signals. The driving circuit and the liquid crystal display device provided by the invention can improve the display effect.
Description
【Technical field】 [0001] The invention relates to the technical field of displays, in particular to a driving circuit and a liquid crystal display device. 【Background technique】 [0002] With the continuous development of the display, there are more and more display modes of the display. For example, the display modes of existing displays include two-dimensional and three-dimensional display modes, that is, two-dimensional display and three-dimensional display can be realized simultaneously. However, the existing displays have the problems of insufficient charging and discharging capability and high temperature of the driving chip, which restrict the further development of the displays. [0003] At present, the problems in the prior art are solved by changing the pixel arrangement structure of the display and the driving mode of the pixels. But for the pixel design of the gate line parasitic capacitance (Cst on gate). Such as figure 1 as shown, figure 1 Given the pixel ...
