Abstract

The present invention relates to a liquid crystal display panel driving circuit, which comprises a plurality of parallel scanning lines, a plurality of parallel data lines which are insulated and intersected with the scanning lines, a scanning driving circuit, a data driving circuit, a signal output circuit and a Select the output circuit. The scan line and the data line define a plurality of pixel units. The scan driving circuit is used to output multiple scan signals. The data driving circuit is used to output multiple data signals. The signal output circuit is used to output a plurality of signals, and the signals are black and white signals arranged at intervals of a frame. The selection output circuit is used to receive the data signal output by the data driving circuit and the signal output by the signal output circuit, and selectively output the black signal or the data signal to the data line according to the received black signal or white signal. In addition, the present invention also provides a liquid crystal display panel using the above driving circuit and a driving 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...
