Abstract
A method and the device for position detection are disclosed. The device comprises a plurality of strips intersecting each other to form a plurality of intersecting regions. A pair of depressed strips intersecting on an intersecting region contact to each other on a contact point to form a depressed intersecting region. According to the voltages of each strip before and after the strip is depressed, an error ratio can be determined. Based on the error ration, the position error caused by the contact impedance crossover strips can be corrected.
