Abstract

The invention discloses an improved GF structure touch screen and an FPC connection method thereof. The touch screen has a laminated structure, which consists of a glass cover plate, a first sensing electrode layer, a PET film layer and a second sensing electrode layer from top to bottom. , the first sensing electrode layer is arranged on the lower surface of the glass cover, the second sensing electrode layer is arranged on the PET film layer, the PET film layer is provided with a through hole, and the second sensing electrode layer is connected through the through hole To the corresponding electrode unit on the first sensing electrode layer, the FPC is connected to the electrode lead-out pin of the first sensing electrode layer by thermocompression; the PET film layer and the glass cover are bonded together by optically transparent glue. Optically transparent glue adopts OCA glue. FPC with touch IC.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an improved GF structure touch screen and an FPC connection method thereof. Background technique [0002] As an intelligent human-computer interaction interface product, the touch screen has been more and more widely used in many fields of social production and life, especially in the field of consumer electronics (such as smart phones, tablet computers, etc.) fastest. [0003] There are many types of touch screen technologies, mainly including resistive, capacitive, infrared, surface acoustic wave and so on. Capacitive touch screen not only has the advantages of sensitive response and multi-touch support, but also has a long life. With the maturity of related control IC technology and the reduction of cost, capacitive touch screen has become the mainstream technology in the market. [0004] The current mainstream capacitive touch screen is generally GG structure, such as...
