Abstract

The invention provides a liquid crystal display pixel drive circuit and a TFT (thin film transistor) substrate. The liquid crystal display pixel drive circuit comprises a plurality of sub-pixels in array arrangement, wherein each sub-pixel comprises a main area TFT, a main area charge-sharing thin-film transistor, a secondary area TFT, a secondary area charge-sharing TFT, a main area storage capacitor, a secondary area first storage capacitor, a main area liquid crystal capacitor and a secondary area liquid crystal capacitor, wherein the main area charge-sharing TFT and the secondary area charge-sharing TFT are connected to first array substrate and second array substrate common voltage separately; the common voltage of the liquid crystal display is adjusted through the size of the first array substrate and second array substrate common voltage, so that the optimum common voltage adjustment difficulty and accuracy of the liquid crystal display can be reduced, and the optimum common voltage adjustment difficulty and display effect of the liquid crystal display are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display pixel drive circuit and a TFT substrate. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is one of the most widely used flat panel displays at present, and a liquid crystal panel is a core component of the liquid crystal display. A liquid crystal panel is generally composed of a color filter substrate (ColorFilter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFTArray Substrate), and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. Generally, pixel electrodes and common electrodes are respectively arranged on the array substrate and the color filter substrate. When a voltage is applied to the pixel electrode and the common electrode, an electric field will be generated in the liquid crystal layer, which determines the orientation of the liquid cr...
