A display device includes a sensing driver, a memory, a first compensator, and a second compensator. The sensing driver measures a first voltage value applied to a light emitter in a pixels. The memory stores a second voltage value previously measured for the pixel. The first compensator calculates a temperature of the light emitter at a time of measuring the first voltage value, and compensates for the first voltage value based on the temperature. The second compensator compensates for input data for the pixel based on a voltage variation obtained from the temperature-compensated first voltage value and the second voltage value.
