Embodiment Construction

[0020] An embodiment of the present invention is given below in conjunction with accompanying drawing 3 to describe the technical solution of the present invention in detail.

[0021] A method in which the display screen and the driving part share a layer of anisotropic conductive film connection during the liquid crystal production process. Considering that the ACF technical standard of COG is higher than that used for FOG, the ACF technical standard of COG will now be used The increased width of the ACF enables it to cover the crimp area of ​​both the first and second ACF layers. After the chip crimping process is completed, it directly enters the hot pressing FPC process, so that the existing ACF replaces the first layer ACF and the second layer ACF in the prior art. and change the production flow to:

[0022] Attaching the ACF to the crimping area 8 covering the crimping chip area 1 and the thermal pressing area 4 in the prior art on the glass substrate 7 of the display s...

Abstract

The present invention relates to a connection method for a display and driving parts sharing an anisotropic conductive film, which includes the steps as follows: S1. A widened ACF is affixed to a chip pressing region which covers the glass substrate of the display and the Regional pressing region of a heat pressure region; S2. A chip is pressed and connected at the chip pressing region on the ACF; S3. The glass substrates of the display and the heat pressure region of FPC flexible circuit board are pressed by heat. Compared with the traditional production method, the method decreases the production process, reduces the investments of production equipments and production materials, and reduces the production cost; in addition, the function and quality assurance of products made by the invention are the same to products made by the prior art.

Description

technical field [0001] The present invention relates to a process of connecting the display screen and the driving part in the production process of the liquid crystal display module, specifically about COG (chip on glass, the process of directly connecting the IC integrated circuit and the liquid crystal display LCD through the ACF) , FOG (film on glass, the process of connecting the flexible circuit board FPC to the liquid crystal display through the ACF) shares a layer of ACF (Anisotropic conductive film, an anisotropic conductive film used in the microelectronics connection process). Background technique [0002] As shown in Figure 1, the ACF contains a considerable number of conductive metal balls 9, and the surface of each ball is covered by an insulating layer. When the electrodes in the drive part and the display part need to be connected to each other, the conductive metal balls 9 in the ACF are subjected to Under the action of certain pressure and temperature, the ...
