A scan sense driver includes a scan driver and a sense driver. The scan line driver provides a scan line enable signal based on a plurality of clock signals, a global clock signal, and a scan input signal during a scan time interval. The sense driver provides a sense enable signal based on the clock signals and a sense input signal during a sense time interval. The sense driver provides the sense enable signal during a period when an organic light-emitting diode of a pixel is to be tested for a malfunction.
