Abstract:
A sensing circuit includes a first input selecting circuit connected to a first sensing line and a second sensing line, a first path setting circuit that sets a path of a first sensing signal received from the first sensing line or a path of a second sensing signal received from the second sensing line, a second path setting circuit that sets a path of a sensing reference voltage, a first switch matrix connected to the first path setting circuit and the second path setting circuit, a first mode setting circuit connected to a first output terminal of the first switch matrix, a first common sensing amplifier connected to the first mode setting circuit, a second mode setting circuit connected to a second output terminal of the first switch matrix, and a second common sensing amplifier connected to the second mode setting circuit.
