Embodiment Construction

[0024] like figure 2 , 3 As shown in , 4, the capacitive touch screen shown in the present invention includes a transparent substrate 20, usually made of transparent glass. One side of the substrate 20 is a film surface 21 , and the other side is an air surface 22 . The film surface 21 side of the substrate is provided with a touch screen film layer 10 facing the backlight to sense the signal generated at the touch point and transmit it to the chip through the metal trace to calculate the position of the touch point. A mask layer 30 is provided between the substrate film surface 21 and the touch screen film layer 10 .

[0025] The touch screen film layer 10 generally includes an ITO layer 11 and a conductive layer 12 , and the metal wiring 12 a in the conductive layer 12 is used to electrically connect the ITO layer 11 to the chip. In order not to affect the visibility of the backlight source of the touch screen, the metal traces 12 a are usually distributed around the fil...

Abstract

The invention relates to a capacitor type touch-control screen, comprising a substrate provided with an air surface and a film surface as well as a touch-control screen film layer arranged at the film surface side of the substrate; the touch-control screen film layer comprises an ITO layer, an insulation layer, a conduction layer and a film layer protection layer; the conduction layer is internally provided with running metal distributed around the substrate; and a mark layer capable of masking the running metal is arranged between the film surface of the substrate and the touch-control screen film layer. By arranging the mark layer capable of masking the running metal between the film surface of the substrate and the touch-control screen film layer, a transparent cover plate arranged at the air surface side of the substrate is avoided, therefore, transmittivity of the touch-control screen panel is enhanced, reflectivity of the film layer is reduced, the integral ground color of the touch-control screen is uniform and the visual effect is improved; the contrast of the touch-control screen is improved and the working efficiency of the backlight can be reduced. Meanwhile, all the film layers are arranged at the film surface side of the substrate, thus ensuring the levelability of the air surface of the substrate. The invention further provides a process method for the capacitor type touch-control screen.

Description

【Technical field】 [0001] The invention relates to a touch screen, and more specifically, to a capacitive touch screen and a processing method thereof. 【Background technique】 [0002] The capacitive touch screen generally includes a substrate, and a film layer is provided on the film surface of the substrate near the backlight source. The film layer usually includes an ITO layer, an insulating layer, a conductive layer and a film protection layer in sequence. The ITO layer is provided with multiple wire traces in two directions criss-crossing for the position of the sensing contact; the insulating layer is used to insulate the ITO layer and the conductive layer; the conductive layer is provided with the wires in the ITO layer The trace is electrically connected to the metal trace of the chip. In order to avoid the influence of the metal trace on the visible area in the middle of the touch screen, the metal trace is usually arranged around the touch screen; the film protective...
