Abstract: An input sensing device includes: sensor pixels, a horizontal driver, a selection circuit, and a vertical driver. Each of the sensor pixels is connected to a plurality of driving lines and a one of a plurality of signal input lines. The horizontal driver sequentially applies a horizontal driving signal to the sensor pixels through the driving lines. The selection circuit is connected to n of the signal input lines (n is a natural number of 2 or more) and to one output line. The selection circuit sequentially outputs n sensing signals received through the n signal input lines to the one output line. The vertical driver receives the n sensing signals through the one output line. The horizontal driver applies the horizontal driving signal n times to a given one of the driving lines to correspond to the n sensing signals.
