A display device includes a pixel component including first pixels which emits light having a first color, and second pixels which emits light having a second color different from the first color, a sensing component which extracts, during a sensing period, first sensing data from the first pixels, and second sensing data from the second pixels, and a temperature determiner which senses a temperature of the pixel component using the first sensing data and the second sensing data. The temperature determiner senses, when the first sensing data is supplied to the temperature determiner, the temperature of the pixel component at least one time.

Display device including temperature determiner and method of driving the same

A display device includes: a low drop-out ('LDO') regulator which provides a second power voltage to a power line during a first period of one frame; a buck converter which provides a first power voltage to the power line during a third period of the one frame; and a pixel connected to the LDO regulator and the buck converter through the power line. A voltage level of the second power voltage is equal to a voltage level of the first power voltage.
