1. A display device, comprising: a display panel configured to display an image based on output image data into which input image data is converted; a voltage curve controller configured to calculate a peak white grayscale and a full white grayscale based on a scale factor mode set by a user, and to generate compensated voltage curves including a first compensated voltage curve having a second point with respect to a maximum grayscale and a fourth point with respect to an intermediate grayscale generated by normalizing a first point and a third point of a first reference voltage curve with respect to the peak white grayscale and the full white grayscale based on an entire grayscale; and a driving voltage controller configured to generate a driving voltage from the compensated voltage curves based on a load of the input image data and a maximum grayscale value of the input image data, and to provide the driving voltage to the display panel.
