Abstract

The invention relates to a liquid crystal display panel drive circuit, which comprises a plurality of parallel scanning lines, a plurality of parallel data lines insulated and intersected with the scanning lines, a scanning drive circuit, a data drive circuit, a signal output circuit and a select output circuit. The scanning lines and the data lines define a plurality of image element units. The scanning drive circuit is used to output a plurality of scanning signals. The data drive circuit is used to output a plurality of data signals. The signal output circuit is used to output a plurality of signals, and the signals are black signals and white signals which are arranged at intervals with frame as unit. The select output circuit is used to receive the data signals output by the data drive circuit and the signals output by the signal output circuit, and to select and output the black signals or the data signals to the data lines according to the black signals or the white signals received. Moreover, the invention also provides a liquid crystal display panel adopting the drive circuit, and the drive method of the liquid crystal display panel.

Description

technical field [0001] The invention relates to a liquid crystal display panel, a driving circuit and a driving method thereof. Background technique [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display panels are widely used in modern information equipment such as televisions, notebook computers, mobile phones, and personal digital assistants. Currently, the application of LCD panels in the TV market is becoming more and more important. However, the liquid crystal itself is a substance with a viscosity coefficient, which causes the response speed of the liquid crystal display to be unable to compete with the CRT display. [0003] see figure 1 , is a schematic diagram of a driving circuit of a liquid crystal display panel in the prior art. The liquid crystal display panel drive circuit 10 includes a plurality of scanning lines 13 parallel to each other, a plurality of data lines 14 parallel to each other and perpendicular...
