<p>PURPOSE: A touch panel using light sensing method and a touch location detecting method using the same, and a recording medium storing program to execute the method are provided to increase the accuracy of position detection without using an additional device while maintaining high resolution. CONSTITUTION: Optical sensing circuits(111) are arranged in matrix format, and generate optical sensing data depending on the brightness of an incident light. A scan driver(130) applies a scan pulse to the scan lines sequentially. Data lines transfer the optical sensing data of the optical sensing circuits arranged on the column to which the scan pulse is applied. A data receiver(140) generates touch data by receiving the optical sensing data, and a point calculating unit judges a touch point by using touch data.</p> |
