Method and apparatus for increasing detection rightness for contact-controllable detector

Abstract

Discrete plural resistance elements are printed or coated on perimeter of electro-conductive film surface of the inductor. Gap components with different size are formed between each row of resistor element. Multiple insulator components of different size are etched on inner side of each row of resistor element group. Gap components of different size are formed between each adjacent insulator components. Thus, resistance regions are formed based on gap components. Each small area with voltage gradient or electric field gradient is formed on the periphery of each independent resistor element and each insulator component in order to cancel out potential difference between each corner. Further, straight type X, Y axial equipotential line can be obtained.

Description

Technical field [0001] The present invention relates to a method and device for increasing the detection accuracy of a touch detector, in particular to a more accurate X and Y axis on the detector when a contact is made on a touch panel. The equipotential line signal coordinates of . Background technique [0002] Please refer to the attached Figure 7 As shown, the known touch detector is on the surface of transparent or translucent substrate A, evenly coated with a thin conductive film B (i.e. ITO layer); a rectangular conductive material C (such as silver Slurry line) printed on the four edges of the conductive film B to form a linear pattern, the four wires W1, W2, W3, W4 are connected to the four corners of the conductive material C, and two of the corners C2, C4 are given appropriate positive values Voltage, the voltage of 0V applied to the other two corners C1 and C3 forms an electric field on the surface of the conductive film B; at this time, the impedance (or condu...

Problems solved by technology

[0007] The disadvantage of this case is that the conductive material is continuous, so when the corner contact is input with an appropriate voltage, the voltage drop ratio between each adjacent corner is quite large, and the voltage drop is reduced only by a single row of insulator regions and resistive electrodes. In other words, there will still be relatively large arc-shaped equipotential lines around the effective touch area of ​​the sensor, so that the action area needs to be a certain distance from the wiring area to avoid the arc-shaped equipotential effect. position shift phenomenon
