Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

The utility model discloses an integrative black capacitive touch screen, include carrier 1 and be located the touch conducting layer above the carrier. The touch conducting layer comprises a BM layer 2, a first IM layer 3 arranged on the BM layer 2, a first ITO layer 4 arranged on the first IM layer 3, a first insulating layer 5 arranged on the first ITO layer 4, a second ITO layer 6 manufactured on the first insulating layer 5, a metal layer 7 arranged on the second ITO layer 6, a second IM layer 8 arranged on the metal layer 7, and a second insulating layer 9 arranged on the second IM layer 8. The carrier 1 is typically glass or a film on which the touch conductive layer is made.

The utility model discloses the touch conducting layer is including utilizing the BM layer of yellow light photoetching process preparation, utilize the first IM layer (Index match) that is located above the BM layer of coating film sputtering process preparation, the refractive Index matches, utilize coating film sputtering and yellow light photoetching, the first ITO layer (indium tin oxide) that is located above the first IM layer of etching process preparation, the first insulation layer that is located above the first ITO layer that utilizes yellow light photoetching process preparation, utilize coating film sputtering and yellow light photoetching, the second ITO layer that is located above the first insulation layer of etching process preparation, utilize coating film sputtering and yellow light photoetching, the metal level that is located above the second ITO layer of etching process preparation, the second IM layer that is located above the metal level that utilizes coating film sputtering preparation, and utilize the second insulation layer above the second IM layer of yellow light photoetching process preparation. The second IM layer of the golden finger region is removed by special process (such as printing and etching process)

A BM layer (Black matrix) of the touch conductive layer, which is a Black matrix layer, mainly functions to prevent screen light leakage and to wire, is manufactured by a photolithography process using a Black negative photosensitive material.

The first IM layer and the second IM layer of the touch conductive layer are both manufactured by a coating sputtering process. IM (index match), the reflectivity of which in the visible light area is close to that after the ITO film is plated, reduces the color difference between the ITO film and the etching area, achieves the invisible effect and plays the role of hiding the circuit. The conventional OGS only has one layer of IM, usually only has a hiding effect on a line of a visible area, and cannot realize the visual consistency of colors of a BM area and the visible area in a breath screen state. And this integrative black touch conducting layer of OGS adopts two-layer IM, owing to has had one more IM layer, can be with fine hidden circuit, can have better regulating effect to optics again, can realize that the BM district keeps unanimous with the colour of visual region under the breath screen state, reaches good effect. In addition, the second IM layer also can play the guard action to the rete that covers below it, and relative one deck IM product has had more protection once to promote the security and the reliability of product.
