A driving method for a liquid crystal display device is provided. The liquid crystal display device has a wide viewing angle mode and a narrow viewing angle mode. The driving method includes: in the wide viewing angle mode, all the frames of the liquid crystal display device have the same display brightness; in the narrow viewing angle mode, the odd frames and the even frames of the liquid crystal display device have different display brightness. In the narrow viewing angle mode of the liquid crystal display device, by using an alternate driving method of bright frames and dark frames, the mura degree is significantly reduced, and the smoothness of dynamic picture display is improved, thereby improving the use experience of users.

Driving method for liquid crystal display device

A thin film transistor array substrate comprises a transparent substrate, and scanning lines, data lines and pixel regions that are formed on the transparent substrate. Each pixel region comprises a pixel electrode, a thin film transistor for controlling the pixel electrode, a first push alignment electrode and a second push alignment electrode. Projections of the first and second push alignment electrodes on the transparent substrate are located on two opposite sides of the pixel electrode. The pixel electrode is covered with an insulation layer and the insulation layer is provided with a pull alignment opening. When the thin film transistor array substrate is in operation, an oblique pull electric field is formed at the pull alignment opening, and transverse push electric fields are formed between the first push alignment electrode and the pixel electrode as well as between the second push alignment electrode and the pixel electrode, respectively.

A liquid crystal display panel includes a first and second substrates which are opposite, and further includes scanning lines, data lines, pixel electrodes and switches, intersection of two adjacent scanning lines and data lines forming a pixel region. The pixel electrodes are disposed in pixel regions. Each pixel electrode crosses one data line and includes a first and second sub-pixel electrodes which are electrically connected to each other; the first and second sub-pixel electrodes are arranged on two sides of the data line; there is a gap between the first and second sub-pixel electrodes, and the data line is configured in the gap. A problem that conventional liquid crystal display panel has a complex manufacture process, leaks light at a dark state and has a low penetrability can be solved, thereby improving yield of the products.

A TFT array substrate includes a plurality of scanning lines, a plurality of data lines and a plurality of pixel regions. Each pixel region includes a pixel electrode, a first TFT, a pull alignment electrode, a second TFT, a first and second push alignment electrodes, so that when a voltage is applied to the TFT array substrate, a transverse pull electric field is formed between the pixel electrode and the pull alignment electrode, and transverse push electric fields are formed respectively between the first push alignment electrode and the pixel electrode and between the second push alignment electrode and the pixel electrode. Accordingly, liquid crystal molecules of the TFT array substrate can respond quickly and it is not necessary to configure bumps on a color filter substrate, thereby improving contrast ratio, simplifying manufacture process and reducing costs.

The present invention provides a liquid crystal display and an array substrate thereof. The array substrate comprises scan lines, data lines and a plurality of pixel defined by a crosswise arrangement of the scan lines and the data lines. The pixel comprises a first sub-pixel electrode; a second sub-pixel electrode electrically isolated from the first sub-pixel electrode; a first switching element for controlling the first sub-pixel electrode; and a second switching element for controlling the second sub-pixel electrode. When the control of the first sub-pixel electrode by the first switching element cannot be carried out normally, the second switching element can control at least a part of the first sub-pixel electrode in place of the first switching element.
