Problems solved by technology

However, the area between two adjacent driver ICs 12 is, for example, a space 15 between the driver ICs 12a and 12b, or an area between two adjacent pin groups 13, such as It is at the interval 14 between the pin groups 13a and 13b. The adhesion of the anisotropic conductive film is poor, so the anisotropic conductive film is not easy to attach, which in turn affects the config

Abstract

The display assembly includes one glass substrate, one first set of pins, one second set of pins and several dummy pins. The first set of pins and the second set of pins are configured in the edges of the glass substrate. One flexible printed circuit is configured on the first set of pins and the second set of pins via the first anisotropic conductive film. The dummy pins are set between the first set of pins and the second set of pins on the glass substrate. When the first anisotropic conductive film is adhered on the set of pins and the second set of pins, it is also adhered onto the dummy pins to increase the adhesion between the glass substrate and the first anisotropic conductive film. The design with increased wires of the present invention can raise the adhesion of the anisotropic conductive film, and this avoid forming residual adhesive and poor stitching.

Description

(1) Technical field [0001] The present invention relates to a display component, and in particular to a display component with increased adhesion of an anisotropic conductive film. (2) Background technology [0002] Due to the liquid crystal display has the advantages of full flat and thin body, small space occupation, thin panel thickness, light weight, flat right-angle display, low power consumption, low electromagnetic wave radiation, low heat radiation, etc., it gradually replaces the traditional Cathode Ray Tube monitors (Cathode Ray Tube, CRT) became the standard equipment of the computer. [0003] The manufacturing process of the liquid crystal display module (Liquid Crystal Display Module, LCD Module) is to use two glass substrates, respectively constructing a color filter and a thin-film transistor (Thin-film Transistor, TFT) on the surface of the two glass substrates, respectively. A color filter (Color Filter, CF) substrate is formed and a TFT substrate is formed...
