A driving circuit includes a sensing component including a sensing channel shared by a first sub-sensing line connected to a first pixel and a second sub-sensing line connected to a second pixel, and a timing controller that converts input data supplied from an external device in response to sensing data supplied from the sensing component, and generates output data. The sensing component further includes a sampling line that receives a first sensing voltage from the first sub-sensing line and a second sensing voltage from the second sub-sensing line, and a sampling switch connected between the sampling line and the first and second sub-sensing lines. The sampling switch is turned on during a first time the first sensing voltage is supplied to the sampling line, and is turned on during a second time different from the first time the second sensing voltage is supplied to the sampling line.
