Method for judging touch position

The invention relates to a method for judging a touch position, which is suitable for an optical touch panel, wherein a plurality of visible light and invisible light sensors which are arranged in a matrix mode and are respectively corresponding to each other are arranged in the optical touch panel. The method comprises the following steps: reading sensing signals of each visible light sensor andeach invisible light sensor; converting the sensing signal of each visible light sensor into first binary codes according to first set parameters, and converting the sensing signal of each invisible light sensor into second binary codes according to second set parameters and third set parameters; and carrying out an AND operation on all the first binary codes and all the second binary codes to acquire a plurality of logical operation values to judge the touch position of a user on the optical touch panel.
