Abstract

The present invention relates to a liquid crystal display panel and the driving method thereof. The liquid crystal display panel comprises a plurality of scan lines, a plurality of control lines, a plurality of first pixel units, a plurality of second pixel units and a plurality of data driving chips. The data driving chips comprise a plurality of output ends. Under the control of the scan lines and the control lines, during the period of applying signals to one row of scan lines, the output ends firstly output a first gray-scale voltage to the first pixel units and the second pixel units, andthen output a second gray-scale voltage to the second pixel units. The present invention also provides a driving method for the liquid crystal display panel.

Description

technical field [0001] The invention relates to a liquid crystal display panel and a driving method thereof. Background technique [0002] Liquid crystal display panels have been widely used in electronic devices such as televisions, notebook computers, mobile phones, and personal digital assistants due to their low radiation, thin thickness, and low power consumption. [0003] see figure 1 , is a schematic diagram of an equivalent circuit of a prior art liquid crystal display panel. The liquid crystal display panel 10 includes a plurality of data driving chips 110, a plurality of scanning driving chips 112, a plurality of scanning lines 142 parallel to each other, a plurality of data lines 141 parallel to each other and perpendicular to the scanning lines 142, and a plurality of A thin film transistor (thin film transistor, TFT) 101 , a plurality of pixel electrodes 102 , a plurality of common electrodes 103 and a plurality of storage capacitors 104 at the intersection of...
