Abstract

In the invention, one display unit possesses structure of two thin film transistors (TFT). First scanning voltage is provided for multiple first scanning lines to drive grids of multiple first TFTs. First signal voltage provided on multiple first signal lines is utilized to drive source poles of multiple TFTs. second signal voltage provided on multiple second scanning lines is utilized to drive grids of multiple second TFTs. Second signal voltage provided on multiple second signal lines is utilized to drive sources of multiple second TFTs. moment of providing second scanning voltage and second signal time is identical to or delayed to moment of providing second scanning voltage and second signal time.

Description

【Technical field】 [0001] The present invention relates to a driving method of a matrix liquid crystal display panel, in particular to a driving method of an active matrix liquid crystal display panel with a display unit having two TFT structures. 【Background technique】 [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal displays are widely used in modern information equipment such as televisions, notebooks, computers, mobile phones, and personal digital assistants. At present, the application of liquid crystal displays in the TV market is becoming more and more important. However, liquid crystal itself is a material with a viscosity coefficient, so its response speed cannot compete with CRT (Cathode-ray tube, cathode ray tube). In an active matrix liquid crystal display, except for the on and off time of the active element, the response time required for the liquid crystal molecules to switch in the gray scale needs to be less tha...
