Abstract

The invention relates to a liquid crystal displaying device which comprises a liquid crystal displaying panel, a scan driving circuit, a data driving circuit and a delay compensation circuit. The liquid crystal displaying panel comprises a plurality of scanning lines and a plurality of data wires which are insulate and orthogonal with the scanning lines. The delay compensation circuit comprises a plurality of capacitors which are corresponding to the scanning lines. The scan driving circuit is used for providing a plurality of scanning signals for the scanning lines. The data driving circuit is used for providing a gray scale voltage for the data wires when the scanning lines are scanned. When the scanning lines are scanned, the corresponding capacitor discharges and provides a compensation signal to the scanning line, and the corresponding capacitor of the next scanning line is charged while the corresponding capacitor of the previous scanning line is discharged to ground.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] As liquid crystal display devices are more and more widely used in various fields, the liquid crystal display devices show a trend of developing toward larger sizes and higher resolutions. However, in a liquid crystal display device using a thin film transistor (Thin Film Transistor, TFT), the high-potential signal of the scanning line is obviously delayed due to the excessively long circuit wiring, thereby causing the problem of screen flickering. [0003] see figure 1 , which is a schematic diagram of a circuit structure of a prior art liquid crystal display device. The liquid crystal display device 100 includes a scan driving circuit 110 , a data driving circuit 120 and a liquid crystal display panel 130 . The scanning driving circuit 110 is used to scan the LCD panel 130 , and the data driving circuit 120 is used to provide graysc...
