Abstract: A display device includes a power generator to supply a driving voltage to the display and a controller to control the display and the power generator and to generate a power control signal. The power generator includes a DC-DC converter and bypass cut-off logic. The DC-DC converter receives an input power voltage and the power control signal, selectively boosts the input power voltage based on the power control signal, and generates the driving voltage. The bypass cut-off logic selectively cuts off supply of the input power voltage to the DC-DC converter based on the power control signal.
