Embodiment 1

[0037] like image 3 As shown, the first adhesive layer 13 in this embodiment is provided with an anti-interference material and an insulating material, and the first adhesive layer 13 is an optical adhesive. When preparing the optical adhesive, the anti-interference material and the insulating material are combined. It is doped into the solvent for preparing the optical glue, and after the preparation is completed, it is attached between the transmitting layer 12 and the receiving layer 14 to play the role of insulation and anti-interference. Since the touch screen 10 is also combined with a structure having a display function to form a touch display panel, the film layer of the touch area AA is required to be a transparent material, so the anti-interference material and the insulating material are both transparent materials.

[0038] Due to the insulation and anti-interference processing performed between the transmitting layer 12 and the receiving layer 14, the routing of t...

Embodiment 2

[0041] like Figure 4 As shown, the capacitive touch screen 20 includes a second adhesive layer 21 , a transmitting layer 22 , a first adhesive layer 23 , a receiving layer 24 , and an anti-interference insulating layer 25 .

[0042]Wherein, the anti-interference insulating layer 25 is disposed between the transmitting layer 22 and the first adhesive layer 23 . In this embodiment, the anti-interference insulating layer 25 is disposed at the position of the transmitting layer 25 . The surface of the non-touch area is the surface of the transmitting layer 25 close to the receiving layer 23 .

[0043] In this embodiment, an anti-interference insulating layer 25 is provided in the non-display area NA of the transmitting layer 22 , which has the same effect as that in the first embodiment when the first adhesive layer 13 is doped with an anti-interference insulating material. The signal interference between the transmitting layer and the receiving layer is reduced, so that the tra...

Abstract

A capacitive touch screen, with a touch area and a non-touch area arranged around the touch area, including a sending layer, a receiving layer, and a first layer arranged between the sending layer and the receiving layer Adhesive layer; a plurality of first wirings are arranged on the sending layer; a plurality of second wirings are arranged on the receiving layer; anti-interference materials and insulating materials are arranged inside the first adhesive layer, or, the sending layer and the first An anti-interference insulating layer is arranged between the adhesive layers; the orthographic projections of the first wiring and the second wiring overlap on the capacitive touch screen. By providing an insulating film layer between the sending layer and the receiving layer, the signal interference between the sending layer and the receiving layer is reduced, so that the wiring of the sending layer and the receiving layer in the frame area can be overlapped in different planes, Thus narrowing the frame of the touch screen.

Description

technical field [0001] The present invention relates to the technical field of touch control, and in particular, to a capacitive touch screen. Background technique [0002] In the field of commercial display, touch technology is usually used as educational whiteboards and high-end conference machines. In order to facilitate operation and presentation, large-size touch screens are required. The current mainstream touch technology is infrared technology. Although the price of infrared touch screen is cheaper than that of capacitive touch screen, the touch experience is poor. At present, capacitive touch screen is more and more popular due to its relatively sensitive touch experience. The more users love it. [0003] However, at present, the frame of the capacitive touch screen is similar to that of the infrared touch screen, and there is a problem that the frame is relatively wide. The frame area is generally used to arrange the conductive lines connecting the touch electrode...
