Embodiment 1

[0039] Such as figure 1 As shown, Embodiment 1 is an improvement on the prior art GMM structure touch screen, specifically including the upper line layer 10, the first substrate layer 20, the optical glue 30, and the lower line layer stacked in sequence from outside to inside. 40 . The second substrate layer 50 .

[0040] Both the upper line layer 10 and the lower line layer 40 include: an optical filling layer 5, a touch pattern 4, and a silver paste line 2; the touch pattern 4 is provided on the outside of the optical filling layer 5, and the touch pattern 4 is formed by a mold or other methods. In the depression formed on the optical filling layer 5 , the silver paste circuit 2 is filled in the touch pattern 4 , and a layer of black ink 3 is laid on the outside of the silver paste circuit 2 .

[0041] The wedge-shaped privacy-preventing structures 1 are densely arranged in the optical filling layer 5 of the upper line layer 10 , and the wedge-shaped privacy-preventing str...

Embodiment 2

[0043] Such as figure 2 As shown, the difference from Embodiment 1 is that: the wedge-shaped privacy-preventing structure 1 is located in the optical filling layer 5 of the downline circuit layer 40 , and the wedge-shaped privacy-preventing structure 1 and the second substrate layer 50 form a privacy-preventing layer.

Embodiment 3

[0045] Such as image 3 As shown, the difference between the third embodiment and the first embodiment is that the first substrate layer 20 and the second substrate layer 50 are canceled in the third embodiment, and the upper circuit layer 10 and the lower circuit layer 40 are bonded by optical glue 30 Together, the plane where the wedge-shaped anti-peeping structure 1 is located serves as an anti-peeping layer.

Abstract

The invention belongs to the technical field of touch control, and discloses a touch screen integrated with an anti-peeping function and a production process thereof, an anti-peeping structure is integrated in a touch screen structure, according to different types of touch screen structures, one or two layers of base materials can be saved, a UV adhesive layer is filled, and the purposes of overall thinning, manufacturing process and cost saving and the like can be achieved; and in combination with the peep-proof structure, part of poor appearance of the touch screen can be shielded, so that the appearance yield of the touch screen is indirectly improved.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch screen with an integrated anti-peeping function and a production process thereof. Background technique [0002] Metal grid touch devices in the prior art generally include three structures: Figure 8 The GMM structure in, such as Figure 9 The substrate-free MM structure in , and as Figure 10 The M2 structure in . [0003] Among them, the GMM structure includes the upper line layer, the first base material layer, optical adhesive, the lower line layer, and the second base material layer; the substrate-less MM structure includes the upper line layer, the photosensitive adhesive layer, and the lower line layer; the M2 structure includes An upper-line circuit layer, a first base material layer, and an off-line circuit layer. [0004] Such as Image 6 As shown, the anti-peeping structure generally adopts a design similar to a louver, and a light-transmitting passage is fo...
