Abstract
The embodiments of the present disclosure relate to a display device, and more specifically, to a display device comprising: a display panel in which a plurality of sub-pixels are disposed; a data driver circuit that applies a plurality of data voltages to the plurality of sub-pixels through a plurality of data lines; a driving voltage supply circuit that supplies a driving voltage to the display panel; and a power management circuit that receives a feedback driving voltage from the display panel, receives the driving voltage output from the driving voltage supply circuit, and outputs a gamma reference voltage to the data driver circuit. The power management circuit includes a register that stores data related to variation in the driving voltage. The gamma reference voltage is variable according to the feedback driving voltage. As a result, a gamma reference voltage that is not affected by noise can be generated.
