Description

Technical Field

[0001] The utility model relates to a display module, more specifically, to a display module structure for reducing static electricity whitening. Background Art

[0002] The traditional G / G is a standard cover glass + touch layer + display panel layer structure, while InCell and OnCell both integrate the touch layer and the display panel together. The position where the ITO film is embedded in the display panel is the key to distinguishing InCell from OnCell. OnCell places the ITO touch film layer on the upper substrate of the display panel, and its representative manufacturers are Samsung and LG. In-Cell places the ITO touch film layer under the upper substrate of the display panel and integrates it with the liquid crystal layer. Its representative manufacturer is Apple. Since INCELL places the touch film layer (with conductive ability) on the liquid crystal layer, when external static electricity enters the TFT through the cover plate, if the static electricity accumulates on the touch film layer, a certain electric field will be generated, causing all the liquid crystals to flip, and the light transmittance will increase, causing the problem of whitening.

[0003] Chinese utility model patent document CN216901208U discloses a display panel for reducing static electricity, including a display panel assembly, the display panel assembly includes a display panel body, a panel display area is arranged on the front of the display panel body, and a plurality of wiring assemblies arranged interlaced with each other are arranged on the top and bottom of the front of the panel display area; the wiring assembly includes a panel wiring, the panel wiring is arranged on the panel display area, and one end of the panel wiring is fixedly connected with a widened end. A conductive buffer assembly is arranged on the outside of the display panel body, and the conductive buffer assembly is used to conduct electricity and buffer the display panel body. The conductive buffer assembly includes a conductive part and a buffer part. The conductive part is used to conduct electricity to the display panel body, and the buffer part is used to buffer the display panel body. Such an arrangement can improve the conduction of static electricity and reduce the situation where the display panel body is damaged by external force. The conductive part includes a conductive member, and the conductive member is fixedly arranged on the outer periphery of the display panel body. The buffer part includes a plurality of buffer members, and the plurality of buffer members are embedded in the conductive member. One end of the buffer member extends to the outside of the conductive member, and a plurality of the buffer members are distributed around the display panel body.

[0004] Obviously, the patent sets a wiring assembly, and the widened end of the wiring assembly can make the width of the panel wiring end larger, so that even after etching, the end of the panel wiring will not form a pointed shape, thereby achieving the purpose of reducing static electricity and reducing the situation of product defects caused by static electricity. However, this structure cannot solve the existing problem of whitening of liquid crystal. Utility Model Content
