Pixel electrode and array substrate

Abstract

A pixel electrode, comprising a keel electrode (1) dividing the pixel electrode into at least two electrode areas, wherein a plurality of strip-shaped branch electrodes (2) are arranged in each electrode area, one of two ends of each branch electrode (2) is connected to the keel electrode (1), the branch electrodes (2) in each electrode area extend in the same direction and are arranged in parallel, at least one connecting electrode (3) is arranged in each electrode area, and the connecting electrode (3) is connected to at least two branch electrodes (2). Further provided is an array substrate, comprising a pixel electrode. Compared with the prior art, with the enhancement of an alignment voltage, liquid crystals at the periphery of the pixel electrode and near the keel electrode (1) can be deflected in order by means of a common electrode, so that liquid crystals at the periphery of the connecting electrode (3) are extruded, then, liquid crystals, at the connecting electrode (3), in the pixel electrode are driven to deflect in order, and finally the state of complete segmentation in each direction is achieved, thereby avoiding the phenomenon of disordered domains, and effectively increasing the penetration rate.

Description

technical field [0001] The invention relates to a liquid crystal display panel technology, in particular to a pixel electrode and an array substrate. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] Active Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) is currently the most common liquid crystal display in the mainstream market. According to different liquid crystal driving methods, it can be roughly divided into: twisted nematic (Twisted Nematic, TN) or Super Twisted Nematic (STN) type, In-Plane Switching (IPS) type, and Vertical Alignment (VA) type. Compared with other types of liquid crystal displays, the VA type liquid crystal display has a very high contrast ratio, and has a ver...

Problems solved by technology

[0005] During the alignment process, due to the abnormal voltage caused by the connection between the pixel electrodes, the liquid crystal photoalignment is abnormal.

At the beginning of the establishment of the electric field, when the voltage rises to about 2.0V, a domain segmentation "vortex" appears in the middle of the pixel electrode (such as figure 1 As shown), under normal circumstances, it will slowly diffuse to the entire pixel electrode, but because the pixel electrodes on the array substrate are connected, when there is an electric field around the boundary of the pixel electrode, and there is no obvious difference in the strength of the electric field, it will also appear at the connection. Domain segmentation "vortex", domain segmentation will be affected and cannot be completed, resulting in disordered domain (vortex) phenomenon in alignment
