Abstract:
Disclosed is a device for sensing touch. The device for sensing touch includes: a plurality of electrodes; and a sensing circuit connected with the plurality of electrodes by a plurality of output channels, which is provided so as to correspond to the plurality of electrodes, respectively, and configured to sense a variation of capacitance of the plurality of electrodes from the plurality of output channels, in which the sensing circuit simultaneously senses output data output from a first output channel, a second output channel, a third output channel, and a fourth output channel among the plurality of output channels, the second output channel is adjacent to the first output channel, and the fourth output channel is adjacent to the third output channel, and the first to fourth output channels are connected to an input terminal of a comparing unit including a first input node and a second input node.
