Abstract
Provided is a display device comprising a display panel, a driving controller that receives an input image signal and outputs an image data signal, a voltage generator that generates a plurality of gamma voltages in response to a voltage control signal, and a data driving circuit that receives the plurality of gamma voltages and provides a data signal corresponding to the image data signal to the display panel. The driving controller operates between in a normal mode and in a power-saving mode. During the power-saving mode, the driving controller outputs the voltage control signal for changing voltage levels of the plurality of gamma voltages in response to the input image signal and a peak signal. At least one of the plurality of gamma voltages has a first voltage level during the normal mode and has a second voltage level lower than the first voltage level during the power-saving mode.
