[0002] In display screen module manufacturing field, antistatic performance is a vital technical index, it is directly related to the stability and reliability of product, in order to achieve this goal, manufacturers usually adopt the method of pasting conductive double-sided adhesive tape in the copper leakage area of the back of display screen FPC (flexible circuit board), and the conductive double-sided adhesive tape can effectively connect FPC with other components of module tightly with its good conductivity and adhesion, and prevent static accumulation from causing damage to module.

[0003] However, although the conductive double-sided adhesive tape performs well in antistatic, it faces a severe challenge in practical application-the release film is easy to fall off. Because the area of conductive double-sided adhesive tape is relatively small, this characteristic is particularly prominent in the manufacturing process of FPC supplier. In the manufacturing process, slight improper operation or environmental factors can cause the adhesion between the release film and the conductive double-sided adhesive tape to weaken, and then cause the release film to fall off. In addition, the release film also faces the risk of falling off during the packaging and transportation process. The selection of packaging materials, vibration and impact during transportation and other factors can adversely affect the release film, causing it to peel off from the conductive double-sided adhesive tape. Once the release film falls off, not only will it affect the conductivity and adhesion of the conductive double-sided adhesive tape, causing the connection between FPC and other components of the module to be unstable, but also it may hinder the subsequent assembly work and reduce production efficiency. Therefore, we improve it and propose a display module with conductive double-sided adhesive tape. SUMMARY
