Problems solved by technology

Since the extension direction of the frame 200 is different from the extension direction of the first branch electrode 301, the second branch electrode 302, the third branch electrode 303, and the fourth branch electrode 303, the liquid crystal cannot be displayed in the area corresponding to the frame 200. The first, second, third, and fourth electrode regions 401, 402, 403, and 404 are also along the first branch electrode 301, the second branch electrode 302, the third branch electrode 303, and the fourth branch electrode 303. The direction is poured, so dark lines are prone to appear in the area corresponding to the frame 200
The appearance of dark lines is directly reflected in the transmittance of the pixels, thus affecting the display brightness of the LCD panel.

Embodiment Construction

[0027] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0028] see Figure 2 to Figure 3 , the present invention provides a pixel electrode, comprising: a rectangular frame electrode 20, a plurality of branch electrodes 30 located inside the frame electrode 20 and connected to the frame 20;

[0029] The inner side of the frame electrode 20 includes four electrode areas distributed in a square shape, which are respectively the first, second, third, and fourth electrode areas 41, 42, 43, and 44;

[0030] The plurality of branch electrodes 30 includes: a plurality of strip-shaped first branch electrodes 31 located in the first electrode region 41 inclined at a degree relative to the horizontal direction and distributed parallel to each other at intervals; The strip-shaped second branch electrodes 32 ...

Abstract

The invention provides a pixel electrode which comprises a closed frame electrode, wherein outer parts of at least one pair of opposite edges of the frame electrode have a zigzag structure; and an extending direction of tooth space of the zigzag structure is parallel to and consistent with an extending direction of corresponding branch electrodes of the pixel electrode. In this way, in an area corresponding to the frame electrode, liquid crystal can be poured along the direction of the branch electrodes just like that the liquid crystal is poured in the inner side area of the frame electrode, so that dark fringes appearing in the area corresponding to the frame electrode can be avoided. When the pixel electrode is applied to an HVA type liquid crystal display panel, a penetration rate and luminance of the liquid crystal display panel can be effectively increased, and thus display effects can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel electrode. 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 very wide application in lar...
