Embodiment Construction

[0028] In the existing pixel unit, there are two layers of transparent electrodes in different layers, one of which is used as a pixel electrode, and the other is used as a common electrode. The pixel unit in the advanced display system ADS used is a typical pixel unit with double-layer transparent electrodes. AD-SDS (Advanced-Super Dimensional Switching, ADS for short) wide viewing angle technology, in ADS mode, through the electric field generated by the edge of the slit electrode in the same plane and the slit electrode layer and the plate electrode The electric field generated between the layers forms a multi-dimensional electric field, which makes all the oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes rotate, thereby improving the working efficiency of the liquid crystal and increasing the light transmission efficiency. The pixel electrodes or common electrodes in ADS are set as slit electrodes or...

Abstract

The invention discloses a pixel unit, a pixel structure, a display device and a pixel driving method to solve the problem of high power consumption caused by the fact that data signals inputted into each data line require voltage change in the prior art. Positions of pixel electrodes and public electrodes in each two adjacent pixels of a pixel unit using the dual-grid technique are changed in the pixel unit, the pixel structure is formed by an array consisting of the pixel units, and the pixel driving method corresponding to the pixel structure is provided, so that changing of voltage polarity of data signals inputted into each data linen is not needed during point turning or column turning of pixels, and power consumption is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a pixel unit, a pixel structure, a display device and a pixel driving method. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (hereinafter referred to as TFT-LCD) has the advantages of light weight, thin thickness and low power consumption, and is widely used in electronic products such as TVs, mobile phones, and monitors. In order to develop a low-cost and high-quality TFT-LCD, dual gate technology is usually used to drive pixels in the prior art, so as to shorten the charging time of the pixels and realize low-cost and high-quality image display. [0003] The schematic diagram of the existing pixel unit structure is as follows: Figure 1a As shown, the pixel unit includes two adjacent pixels located in the same row, and each pixel includes a pixel electrode, a common electrode, and a thin-film transistor TFT that drives the corresponding pixel; in...
