Claim Text:
1. A display device, comprising: a panel including a plurality of pixel circuits, each of the pixel circuits comprising a light emitting device comprising a first terminal coupled to a first voltage, and a second terminal coupled to a second voltage; a signal controller configured to: a voltage difference setting unit configured to detect a maximum value of the decreased input image data, and configured to calculate a difference value between the first voltage and the second voltage so that a driving current corresponding to the maximum value is generated; and a power supply unit configured to generate and apply the first and second voltages to the panel, the generated first and second voltages corresponding to the calculated difference value, wherein the gamma curve comprises one or more inflection points and an output image data curve comprises one or more corresponding inflection points corresponding to the one or more inflection points of the gamma curve, and wherein a section of the output image data curve is between one of the one or more corresponding inflection points and the maximum value of the decreased input image data.
