touch screen

Abstract

The invention discloses a touch screen, which comprises an ITO (Indium Tin Oxide) film, a glass cover plate, a plurality of outgoing lines, a plurality of transparent insulation cranes and a plurality of wire jumpers, wherein the ITO film is provided with a conductive pattern, the conductive pattern comprises a plurality of X electrodes and a plurality of Y electrodes, the X electrodes and the Y electrodes are relatively insulated, the X electrodes are kept continuous, and the Y electrodes are disconnected in an area where the X electrodes and the Y electrodes are cross; the insulation cranes are arranged on the ITO film and are used for connecting the Y electrodes on two sides of a disconnected area; and the wire jumpers are arranged on the insulation cranes and are used for conducting the Y electrodes on two sides of the disconnected area. The X electrodes and the Y electrodes are formed on the single-layer ITO film, lap joint is formed through the wire jumpers, the outgoing lines capable of connecting with an IC (Integrated Circuit) controller are arranged, etching can be more conveniently finished, the layer number of the touch screen can be reduced, and therefore, the touch screen is light and thin. In addition, the simplification of the structure is favorable for saving materials, reducing processing working procedures, lowering cost and improving a yield.

Description

technical field [0001] The invention belongs to the technical field of touch screens, in particular to touch screens. Background technique [0002] The capacitive touch screen works by using the induced current of the human body. When a finger touches a certain point on the screen, the touch IC controller of the touch screen needs to obtain the current information of the point in the X-axis direction and the Y-direction to accurately calculate The location of the touch point. Commonly used capacitive touch screens generally use two-layer ITO electrodes, which are used as electrodes in the X-axis direction and electrodes in the Y-axis direction. The two layers of ITO electrodes are respectively deposited on two substrates, and then the two substrates are The materials are bonded with optical glue, and then the upper substrate is bonded with the glass cover plate with optical glue, so that the ITO electrodes in the X-axis direction and the Y-axis direction work on their respe...

AI Technical Summary

Problems solved by technology

Due to the use of two layers of ITO conductive material and two layers of optical glue to make the touch screen, the process is cumbersome and the thickness of the touch screen is high; the wire width of the conductive jumper is large, and the jumper will inevitably be displayed in the display area, affecting the display effect of the touch screen
