Abstract: A scan driver includes a plurality of stages for respectively outputting a plurality of scan signals, an N-th stage of the stages including a shift register for outputting an N-th carry signal based on a frame start signal or based on a carry signal from a previous stage, and an output control block for outputting the N-th carry signal as an N-th scan signal in a display mode, and for repeatedly outputting active periods of the N-th scan signal during an active period of the N-th carry signal in a sensing mode, wherein N is a positive integer.

Abstract: A pixel includes an organic light emitting diode, and a driving circuit configured to supply current to the organic light emitting diode, the driving circuit including a driving transistor configured to control a level of the current flowing in the organic light emitting diode based on a level of a voltage supplied to a data line, and a first transistor including a first electrode electrically connected to an anode of the organic light emitting diode, a second electrode configured to receive an initialization power, and a gate electrode electrically connected to the data line, wherein the first transistor is configured to supply the initialization power to the anode of the organic light emitting diode when the first transistor is turned on such that the organic light emitting diode does not emit light.
