AI Technical Summary

Problems solved by technology

[0003] It can be seen that the circuit design of the general resistive touch screen is to make a single-layer conductive circuit structure on the edge of the substrate 10 to obtain the differential distribution voltage, so it has the following main defects: 1. The resistance uniformity of the edge of the substrate 10 is poor, and the voltage The distribution cannot reach a certain level, and the edge line space L of the touch screen must be controlled at about 20 millimeters (mm), such as Figure 5 As shown, resulting in a small viewing area 60;

[0004] 2. The single-layer circuit structure, the voltage distribution is mainly determined by the uniformity of the resistance of the substrate 10. This structure is greatly affected by the uniformity of the resistance of the substrate 10, resulting in poor accuracy of the click position, that is, the actual click position is different from the signal feedback position. Relatively large gap, generally around + / -5mm
