Abstract: 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.

Abstract: A display device includes: pixels connected to scan lines, data lines, and sensing lines; a power supply which supplies a first driving power source to a first power line, supplies a second driving power source to a second power line, and supplies a third driving power source to a third power line; first switches located on pixel rows, respectively; and second switches located on the pixel rows, respectively. A first switch located on an i-th (i is a natural number) pixel row is connected between pixels located on the i-th pixel row and the first power line, and a second switch located on the i-th pixel row is connected between the pixels located on the i-th pixel row and the second power line. The first switch and the second switch, which are located on the i-th pixel row, are alternately turned on and turned off.
