摘要：
A touch sensing device capable of accurately detecting a touched position on a touch panel includes a touch panel, a conversion unit and a calculation unit. The touch panel having a plurality of horizontal sensing lines and vertical sensing lines generates a plurality of horizontal sensing signals and vertical sensing signals in response to a touch on the touch panel. The conversion unit generates a plurality of two-dimensional (2D) sensing signals according to the horizontal and vertical sensing signals. The calculation unit determines a touched position on the touch panel according to the 2D sensing signals.
