Abstract

The invention provides a touch screen, which relates to the field of touch screens. The touch screen includes a first glass and a second glass, a first surface of the first glass is disposed oppositeto a second surface of the second glass, a first touch area of the first surface corresponds to a second touch area of the second surface, the first ITO layer of the first touch area setting corresponds to the second ITO layer of the second touch area setting, The first surface is provided with a conductive silver paste layer, the conductive silver paste layer comprising a plurality of conductivechannels, the conductive channels comprising a plurality of conductive terminals, the first ITO layer comprising a plurality of first connection points electrically connected to the conductive terminals, and the second ITO layer comprising a plurality of second connection points electrically connected to the conductive terminals through the conductive points. The traces of the second ITO layer arerouted on the first surface of the first glass through conductive points, thereby simplifying the trace structure, reducing the trace area and avoiding the occurrence of node capacitance.

Description

technical field [0001] The present invention relates to the field of touch screens, in particular to a touch screen. Background technique [0002] With the advancement of technology, today's touch screens usually use ITO (Indium Tin Oxides, Indium Tin Oxide) material to realize the touch function. When two layers of ITO are used to realize the touch function, the two layers of ITO are usually etched into ITO conductive lines with different patterns. The two layers of ITO conductive lines form a capacitive sensing unit distributed in an array. When a person clicks on the screen, the electric field of the human body will cause the capacitance change of the capacitive sensing unit. By detecting the capacitance change of the sensing unit, the touch point can be judged. location information. [0003] At present, ITO is usually plated on the surface of two pieces of glass respectively, and the wiring of the ITO layer is respectively arranged on the surface of the two pieces of gl...
