Abstract

The invention relates to a retaining wall of a super narrow frame display panel. The retaining wall mainly includes a TFT substrate, a display area coated at the center of the TFT or CF substrate, a PI phase matching film coated on the display area and the TFT or CF substrate and a sealing frame adhesive arranged on the PI phase matching film and surrounding the display area for one circle and further comprises a photo Spacer (PS) retaining wall arranged between a PanelCut line and an HVA light distribution AU point or a Dummy Blue retaining wall in a non-display area. By the adoption of the retaining wall, a narrow frame product adopting PI&seal Overlap design can be coated from PI to the Cut line, but other designs outside the Cut line are also not influenced, the diversity design of the narrow frame is advantageously increased, the demand of the product market is improved, an assisting role is played from the manufacturing process to the design, the quality demand of the product is improved, the product quality is improved, the product cost is reduced, and the competitiveness of the product in the market is further improved.

Description

technical field [0001] The invention relates to a retaining wall design applied in the field of TFT-LCD. Suitable for a wide range of applications in the industry. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display) is composed of TFT and CF Glass. TFT-LCD is very popular in daily life, such as TV, computer, mobile phone and other display screens. The technology in this field is constantly updated to better serve consumers. . Continuous product upgrades have made higher requirements for TFT-LCD, and higher quality requires LCD to move closer to a narrower frame design. The narrower frame design challenges the higher precision coating of PI film for LCD panels. [0003] The in-plane display area (AA area) of the LCD Panel will be coated with a PI film to provide the rotation mode of the liquid crystal LC (see FIG1), but the current product requirements for borderless design lead to the distance between the display area (AA area) and the edge ...
