Capacitive touch sensor architecture with adjustable resistance and noise reduction method

摘要

A capacitive touch sensor architecture comprises a visible touch area, a plurality of wires, a plurality of winding resistances, and a reference strip capacity sensor. The visible touch area comprises a plurality of strip capacity sensors. The strip capacity sensors comprises end a and end b. said strip capacity sensors comprises a plurality of non-conductive barriers. The strip capacity sensors being used to sense touch signals to calculate touch point coordinate. The winding resistances are attached to both sides of each said strip capacity sensor. The wires have different length according to the position of each strip capacity sensor the wires are connected to. By adding non-conductive barrier into strip capacity sensors the edge resisting rate can be increased. By adding adjustable winding resistance to the two ends of each strip capacity sensors, the resistance difference can be eliminated.
