Abstract
A touch input device includes a touch panel, a driving and sensing circuit, a data memory, and a processor. The touch panel is adapted to receive a touch trace including at least one touch point. The driving and sensing circuit is adapted to drive the touch panel and detect actual signal value V. The data memory is adapted to store a look up table including a plurality of position coordinates and a plurality of calibrating rules f each corresponding to each of the position coordinates. Each of the calibrating rules f can be used to convert actual signal value Vof the touch point of a basic contact area Ato a standard signal value V. The processor is adapted to calculate the position coordinate and calibrate the actual signal value Vof the at least one touch point to a calibrated signal value V'.
