Embodiment Construction
[0031] The capacitive touch screen of the present invention uses an exposure etching process to make required button shapes and lines on the ITO glass. The lead-out method of the touch screen can adopt methods such as FPC or pins or zebra strips. Use the exposure etching process to make the required button shape and circuit on the ITO glass.
[0032] The structure of the first embodiment of the present invention is described in conjunction with FIG. 1 and FIG. 2. The capacitive touch screen of the present invention includes an indium tin oxide layer, a transparent protective layer 8 arranged above the indium tin oxide layer, and the indium tin oxide layer The shape of the key 1 is etched on the top, and each key 1 is led out by one or more etched lines 2 , and the key 1 is connected to the control circuit through the lines 2 . Line 2 can be led out by means of FPC or pins or zebra strips. A liquid crystal display 9 is provided below the buttons 1 and lines 2 , and a liquid c...
