Zusammenfassung:An input sensing device includes: an input sensor including a transmission electrode, a first reception electrode, and a second reception electrode; and a readout circuit configured to provide a transmit signal to the transmission electrode, to receive a first receive signal from the first reception electrode, and to receive a second receive signal from the second reception electrode, wherein the readout circuit includes: a switching circuit configured to transfer the first receive signal and the second receive signal to a first node and a second node, respectively, during a touch sensing period and to transfer one of the first receive signal and the second receive signal to the first node and the second node during a compensation period; a first output circuit configured to convert a signal of the first node into a first sensing signal; and a second output circuit configured to convert a signal of the second node into a second sensing signal.
