Claim Text:
1. A touchscreen device, comprising: a panel unit including a plurality of first electrodes and a plurality of second electrodes; a driving circuit unit simultaneously applying driving signals to M first electrodes among the first electrodes, where M is a natural number equal to or greater than two; a sensing circuit unit detecting capacitance generated in intersections between the first electrodes and the second electrodes so as to output sensing signals; and an operation unit determining whether a touch has occurred, based on the sensing signals, wherein the driving circuit unit generates the driving signals according to an M by N matrix, where N is a natural number equal to or greater than two, wherein elements in first to (fix(M/2)+1) rows of a first column are 1s, and elements in (fix(M/2)+2) to M wherein elements in second to N
