Abstract

The invention discloses a liquid crystal display device and a driving method thereof. The liquid crystal display device comprises a plurality of pixel units, wherein each pixel unit comprises a first common electrode, a pixel electrode, a first thin film transistor, a second thin film transistor and a third thin film transistor; each pixel electrode is positioned above the corresponding first common electrode, and is insulated and isolated from the corresponding first common electrode; each thin film transistor respectively comprises a grid conductor, a source and a drain; each first thin film transistor is electrically connected with the corresponding pixel electrode, and is used for providing a first data signal; each second thin film transistor and each third thin film transistor are respectively and electrically connected with the corresponding first common electrode, and are used for providing a second data signal; the pixel electrodes of the pixel units are insulated and isolated with each other; the first common electrodes of the pixel units are insulated and isolated with each other. The liquid crystal display device has the advantage that the first common electrode of each pixel unit can be independently charged with power in advance, so that the response time is saved, and the display effect of dynamic images is improved.

Description

technical field [0001] The present invention relates to liquid crystal display technology, and more particularly, to a liquid crystal display device and a driving method thereof. Background technique [0002] A liquid crystal display device (LCD) is a component including a display panel and its driving circuit. In a liquid crystal display device, a display panel includes a pair of oppositely disposed substrates and a liquid crystal layer interposed therebetween. Applying a voltage between the pixel electrode and the common electrode on the substrate generates an electric field, which can change the orientation of liquid crystal molecules in the liquid crystal layer, so that the light transmittance of each pixel can be controlled to realize image display. Since liquid crystal display devices have advantages of low power consumption, light weight, and thin thickness, they are widely used as display devices for televisions, notebook computers, tablet computers, mobile phones, ...
