Abstract

The invention relates to the technical field of touch screens and particularly relates to a GG monolayer multipoint borderless touch screen and a preparation process thereof. The touch screen comprises a tempered glass cover plate, a transparent optical adhesive layer and ITO conductive glass, wherein a border wiring area of the ITO conductive glass comprises a transverse wiring area arranged at one end of the touch screen, the ITO conductive glass is provided with a monolayer multipoint electrode pattern of single-end outgoing line, and an FPC is mounted in the transverse wiring area in a press-fitting manner and is connected with an IC chip. According to the GG monolayer multipoint borderless touch screen and the preparation process thereof, the FPC is mounted in the transverse wiring area at one end of the touch screen in the press-fitting manner, and original left and right longitudinal wiring areas are canceled, so that longitudinal sides of the touch screen do not need wiring, and thus, a borderless visual effect is built; ultraviolet illumination is adopted during magnetron-sputtering ITO film plating, so that the photoelectric properties of the ITO conductive glass are improved, only one-time FPC press-fitting is required during preparation, the process is simple, the yield of products is high, and excellent properties and production stability for the touch screen can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a GG single-layer multi-point frameless touch screen and a preparation process thereof. Background technique [0002] The touch screen is an input device that significantly improves the man-machine interface, and has the advantages of intuition, simplicity and speed. Touch screens have been widely used in many electronic products. However, at present, most capacitive touch screens use a multi-layer ITO structure, and the manufacturing process is complicated. Therefore, a single-layer ITO touch screen, especially a touch screen capable of realizing multi-touch, has become a development direction of a capacitive touch screen. [0003] Generally, the touch screen includes signal wires connecting the touch electrodes and an external processor for transmitting electrical signals between the touch electrodes and the processor. In order to cover the signal wires, an opaque bord...
