Embodiment 1

[0068] Such as figure 1 and figure 2 As shown, a GF single-layer multi-point frameless touch screen includes a tempered glass cover plate 6, a transparent optical adhesive layer 7, and an ITO conductive film 1 arranged sequentially from top to bottom. The frame of the ITO conductive film 1 is a wiring The wiring area includes a horizontal wiring area arranged at one end of the touch screen, and the ITO conductive film 1 is provided with a single-layer multi-point electrode pattern with a single-end outgoing line, and the lead-out lines of the ITO conductive film 1 are correspondingly arranged on the horizontal wiring. area, the horizontal wiring area is pressed against FPC2, and the lead wire of ITO conductive film 1 is connected to an IC chip 3 through FPC2.

[0069] In this embodiment, the horizontal wiring area is set on the upper end of the touch screen.

[0070] Further, the single-layer multi-point electrode pattern includes a sensing channel and a driving channel, an...

Embodiment 2

[0112] The difference between this embodiment and embodiment 1 is:

[0113] In this embodiment, the horizontal wiring area is set at the lower end of the touch screen.

[0114] Further, the anti-reflection layer is a nano-titanium oxide silicon layer.

[0115] Further, the FPC2 includes an FPC main body area and an FPC extension area connected to the end of the FPC main body area, the FPC main body area includes gold fingers, and the distance between the gold fingers and the edge of the FPC2 is 8mm. Further, the tempered glass cover plate 6 is divided into a black frame area and a window area, the black frame area includes a vertical black frame area and a horizontal black frame area, and the horizontal black frame area is set corresponding to the horizontal wiring area, so The ITO conductive film 1 is 0.8mm beyond the lateral boundary of the window area, which can improve the visual effect of the boundary.

[0116] In the present embodiment, silver paste is made up of the r...

Embodiment 3

[0132] The difference between this embodiment and embodiment 1 is:

[0133] In this embodiment, the FPC2 includes an FPC body area and an FPC extension area connected to the end of the FPC body area. The FPC body area includes a gold finger, and the distance between the gold finger and the edge of the FPC is 5 mm.

[0134] Further, the anti-reflection layer is a nano-titanium oxide silicon layer

[0135] Further, the tempered glass cover plate 6 is divided into a black frame area and a window area, the black frame area includes a vertical black frame area and a horizontal black frame area, and the horizontal black frame area is set corresponding to the horizontal wiring area, so The above-mentioned ITO conductive film 1 is 0.5mm beyond the lateral boundary of the window area, which can improve the visual effect of the boundary.

[0136] In the present embodiment, silver paste is made up of the raw material of following percentage by weight:

[0137] Silver powder 65%

Abstract

The invention relates to the technical field of touch screens, in particular to a GF single-layer multi-touch frameless touch screen and a preparation process thereof. The touch screen comprises a tempered glass cover plate, a transparent optical glue layer and an ITO conductive film, wherein the wiring area of an ITO conductive film frame comprises a transverse wiring area arranged at one end of the touch screen, single-layer multi-touch electrode patterns realizing single-end wiring are formed on the ITO conductive film, a FPC (flexible printed circuit) is pressed on the transverse wiring area, an outgoing line of the ITO conductive film is connected with an IC (integrated circuit) chip through the FPC, and the tempered glass cover plate is provided with an anti-explosion layer and an anti-reflective layer. According to the GF single-layer multi-touch frameless touch screen, the FPC is pressed on the transverse wiring area at one end of the touch screen, so that wires are not required to be arranged on longitudinal edges of the touch screen, and a flameless visual effect is realized; the GF single-layer multi-touch frameless touch screen has good photoelectric performance, stability and anti-explosion capacity, FPC pressing only needs to be performed once in the preparation process, the process is simple, the yield of products is high, and the good performance and the production stability of the touch screen can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a GF single-layer multi-point borderless 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 bor...
