Abstract: A power supply of the present disclosure includes: a power generator that generates a first driving voltage to be supplied to a timing controller; and a voltage compensator that performs feedback of the first driving voltage and generates a feedback voltage according to a voltage difference between the first driving voltage and a first reference voltage supplied from the power generator. In this structure, the power generator generates a second driving voltage by boosting or dropping the first driving voltage to correspond to the feedback voltage, and may supply the second driving voltage to the timing controller.
