Problems solved by technology

[0003] The two structural types of capacitive screens have their own advantages and disadvantages. The current capacitive screens are developing in the direction of large size and high transmittance. The traditional G+G and G+F+F cannot take care of both.

Embodiment Construction

[0011] In order to make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects obtained easy to understand, the specific implementation manners of the present invention will be further described below in conjunction with the specific drawings.

[0012] The invention discloses a capacitive touch screen structure suitable for double-layer wiring, which includes a glass layer (G) 1 located above and a film layer 5 (Film, referred to as F) located below, and the lower surface of the glass layer 1 is provided with The first ITO layer 2 makes the glass layer 1 act as a glass cover and realize the touch function. A second ITO layer 4 is provided on the film layer 5 , and the first ITO layer 2 and the film layer 5 are bonded together by an optically transparent adhesive (OCA) 3 .

[0013] The materials of the thin film layer 5, the ITO layer, the optically transparent adhesive and the related manufacturing techniques in the p...

Abstract

The invention discloses a capacitive touch screen structure suitable for two-layer cabling. The capacitive touch screen structure comprises a glass layer arranged on the upper portion and a thin film layer arranged on the lower portion. The lower surface of the glass layer is provided with a first ITO layer. The thin film layer is provided with a second ITO layer. The first ITO layer and the thin film layer are bonded together through light-transparent adhesive tape. The capacitive touch screen structure is different from traditional G+F, G+G and G+F+F structures, the glass layer and the thin film layer are adopted, namely, a G+F mode is adopted, the two ITO layers are arranged, cabling is carried out on each ITO layer, and therefore a large-sized product is light and thin and has the high-transmittance performance.

Description

technical field [0001] The invention relates to a capacitive touch screen structure, more precisely, relates to a capacitive touch screen which can be used for double-layer wiring. Background technique [0002] The structure of the capacitive screen in the current technology is roughly divided into G+G, G+F, G+F+F, and OGS. Among them, only G+G and G+F+F can achieve double-layer outlets. The structure of the capacitive screen, and the first G is only used as a protective cover, and the touch function is realized by the second G glass or F+F film. The usual traces are on the ITO on both sides of the G glass or on each layer of ITO on the two layers of film. [0003] The capacitive screens of the two structures have their own advantages and disadvantages. The current capacitive screens are developing in the direction of large size and high transmittance. The traditional G+G and G+F+F cannot give consideration to both. Contents of the invention [0004] In order to solve th...
