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.

Abstract

The present invention provides a pixel electrode, the pixel electrode has a closed frame electrode, and the outside of at least one pair of opposite sides of the frame electrode has a zigzag structure, and the extension direction of the tooth grooves of the zigzag structure corresponds to the The extension directions of the branch electrodes are parallel and consistent, so that in the area corresponding to the frame electrode, the liquid crystal can be poured along the direction of the branch electrode as in the inner area of ​​the frame electrode, so as to avoid dark lines in the area corresponding to the frame electrode. The pixel electrode is applied to the HVA liquid crystal display panel, which can effectively increase the transmittance and brightness of the liquid crystal display panel, thereby improving the display effect.

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 Notebook computer screens, etc., dominate the flat panel display field. [0003] Active thin film transistor liquid crystal displays (Thin Film Transistor-LCD, TFT-LCD) are currently the most common liquid crystal displays in the mainstream market. According to the different liquid crystal drive methods, they can be roughly divided into: twisted nematic (TN) or Super Twisted Nematic (STN) type, In-Plane Switching (IPS) type, and Vertical Alignment (VA) type. Among them, VA-type liquid crystal displays have extremely high contrast ratios compared to other types of liquid crystal displays, and have very wide...
