Abstract
The invention discloses a capacitive touch screen which comprises a glass substrate and an ITO (indium tin oxide) electrode layer deposited on the glass substrate, and is characterized in that the ITO electrode is etched into a plurality of X electrodes along the X-axis direction and a plurality of Y electrodes along the Y-axis direction, wherein the X electrodes are continuously kept in the X-axis direction, the Y electrodes are etched to be disconnected in the area where the X electrodes and the Y electrodes intersect, and the X electrodes in the intersection areaA layer of SiO is plated on the layer2To ensure insulation between the X electrode and the Y electrode, in the SiO2The layer is plated with a layer of molybdenum, aluminum and molybdenum to conduct the Y electrode. And molybdenum-aluminum-molybdenum layers are distributed on the edges of the glass substrate and are corresponding circuits electrically connected with the ITO electrodes. Because the ITO electrodes in the X direction and the Y direction are arranged on the same layer, compared with the traditional touch screen with a multilayer structure, the touch screen saves the process flow, and is lighter, thinner and lower in cost.
