Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] figure 1 For a schematic diagram of the existing pixel electrode structure, please refer to figure 1 , the existing pixel electrodes are mostly rectangular. see figure 2 , when the aspect ratio L / W of the rectangular pixel electrode is less than 3.5, the liquid crystal in the liquid crystal region corresponding to the rectangular pixel electrode can be normally aligned during the process of being lit by the gradually rising voltage difference, and cross-shaped d...

Abstract

An embodiment of the present invention provides a pixel electrode. The pixel electrode includes a frame electrode and a keel electrode. The frame electrode encloses a closed area. The keel electrode is located in the closed area. The first trunk and the second trunk, the first trunk and the second trunk divide the enclosed area into four sub-areas, and the area formed by any two adjacent sub-areas is pagoda-shaped. When the pixel electrode provided by the embodiment of the present invention has a large aspect ratio, the liquid crystal in the corresponding liquid crystal region can be normally aligned, thereby improving the transmittance of the pixel electrode. The embodiment of the invention also provides a driving method of the pixel electrode and a liquid crystal display panel with the pixel electrode.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a pixel electrode, a driving method thereof, and a liquid crystal display panel. Background technique [0002] The liquid crystals in the High-Quality Vertical Alignment (HVA) thin film transistor liquid crystal display panel (Thin Film Transistor Liquid Crystal Display, TFT-LCD) are negative liquid crystals, and electric fields and polymerization techniques need to be used before they are put into use. It is aligned. Because the metal wiring in the HVA TFT-LCD will occupy the pixel space, the aspect ratio of the pixel electrode will be large, and the pixel electrode with a large aspect ratio will cause abnormal alignment of the liquid crystal, which will seriously damage the transmittance of the pixel electrode. . Contents of the invention [0003] Therefore, it is necessary to provide a pixel electrode and its driving method, and a liquid crystal ...
