Example Embodiment

[0021] See image 3 with Figure 4 , image 3 It is a schematic diagram of the first embodiment of the driving circuit of the liquid crystal display device of the present invention. Figure 4 It is a partially enlarged schematic diagram of the driving circuit of the liquid crystal display device shown. The drive circuit 200 of the liquid crystal display device includes a plurality of scan lines 10, a plurality of data lines 20, and a plurality of pixel units 30. The plurality of scan lines 10 are induced with the plurality of data lines 20, which defines the plurality of pixel units 30 with the minimum area intersecting the plurality of data lines 20. The liquid crystal display device is a multi-domain vertical oriented liquid crystal display device.

[0022] The pixel unit 30 includes a first sub-pixel unit 31 and a second sub-pixel unit 32 comprising a first thin film transistor 311 and a first pixel electrode 312, the second sub-pixel unit 32. A second thin film transistor 321 ...

Abstract

The invention relates to a drive circuit and a method for driving a liquid crystal display device. The drive circuit of the liquid crystal display device comprises a plurality of data lines, a plurality of scan lines and a plurality of pixel units. Each pixel unit includes a first sub-pixel unit and a second sub-pixel unit, wherein the first sub-pixel unit includes a first TFT and a first pixel electrode; and the second sub-pixel unit includes a second TFT and a second pixel electrode. The first pixel electrode and the second pixel electrode are respectively connected with the same scan line and the data line through the first TFT and the second TFT, and the first TFT and the second TFT have different parasitic capacitances.

Description

technical field [0001] The invention relates to a driving circuit and a driving method of a liquid crystal display device. Background technique [0002] The liquid crystal in the liquid crystal display device itself does not have luminescent properties, it uses an electric field to control the twisting of the liquid crystal molecules to realize the passage or non-transmission of light, so as to achieve the purpose of display. The liquid crystal driving method of the traditional liquid crystal display device is the twisted nematic mode, but its viewing angle range is relatively narrow, that is, different display effects will be observed when the picture is observed from different angles. In order to solve the problem of the narrow viewing angle of the twisted nematic mode liquid crystal display device, the industry proposes a four-domain vertical alignment type liquid crystal display device, by arranging a plurality of "<" shaped protrusions and grooves on the two substrat...
