Abstract:
An apparatus and a method for detecting position, and a touch panel using the same are provided. The apparatus for detecting position includes a frame, a plurality of first signal sources, a plurality of first signal receivers, a plurality of second signal sources, a plurality of second signal receivers, and a processor. The frame is comprised of a first portion, a second portion, a third portion, and a fourth portion. The plurality of first signal sources are disposed along the first and the second portions to emit the signals configured to detect a coordinate in a first direction. The plurality of first signal receivers are disposed along the third and the fourth portions, corresponding to the plurality of first signal sources, to receive the signals from the plurality of first signal sources respectively. The plurality of second signal sources are disposed along the first and the fourth portions to emit the signals configured to detect a coordinate in a second direction. The plurality of second signal receivers are disposed along the second and the third portions, corresponding to the plurality of second signal sources, to receive the signals from the plurality of second signal sources respectively. When an object is set in a particular position within the frame, the processor, coupled with the plurality of first and second signal receivers, determines the particular position of the object according to the locations of signal receivers and strength variation of their received signals.
