Abstract

The liquid crystal display- panel drive circuit comprises a plurality of scanning lines, a plurality of first data lines insulated intersecting the scanning lines, a plurality of film transistors at the cross point of the scanning lines and the first data lines, a scanning drive circuit, a data drive circuit, an access unit and an output control unit. The scanning drive circuit is used for producing a plurality of scanning signals. The data drive circuit is used for producing a plurality of data signals. The access unit is used for accessing multiple signals output by the data drive circuit. The output control unit is used for receiving the data signals accessed by the access unit and controlling the time for outputting the data signals to the first data lines to make the time in accordance with turn-on time of multiple film transistors.

Description

technical field [0001] The invention relates to a liquid crystal display panel and a driving circuit thereof. Background technique [0002] Liquid crystal display panels have been widely used in electronic display devices such as televisions and notebook computers due to their low radiation and thin thickness. Usually, the liquid crystal display panel needs a driving circuit to drive it. As the size of the liquid crystal display panel increases, the length of the scanning lines of its driving circuit also increases accordingly. However, the increase in the length of the scanning line will increase the delay of the scanning signal, which will cause the flickering problem of the LCD panel. [0003] Please refer to FIG. 1 , which is a schematic diagram of a driving circuit of a liquid crystal display panel in the prior art. The driving circuit 10 includes a plurality of scanning lines 101 parallel to each other, a plurality of data lines 102 parallel to each other and perpen...
