Abstract
A method of detecting touch positions includes; providing an external power voltage which drives a touch panel, sequentially turning on a plurality of lower driving elements connected to the touch panel, Turning on a plurality of upper driving elements connected to the touch panel to readout at least one multi-touched position corresponding to an x-coordinate, while each of lower driving elements is turned on, receiving readout position information corresponding to an x-coordinate, turning on at least one of the upper driving elements connected to the touch panel, turning on the plurality of lower driving elements connected to the touch panel to readout the at least one multi-touched position corresponding to a y-coordinate, while each of upper driving elements is turned on, receiving readout position information corresponding to the y-coordinate, turning on a sensing element, and turning off the sensing element.
