Abstract: A gamma compensation method and a display device using the same are disclosed. The gamma compensation method includes: sensing a level of external illuminance; determining whether the sensed level of external illuminance is equal to or lower than a predetermined illuminance, wherein when the sensed level is equal to or lower than the predetermined illuminance, the luminance of the display device is reduced to an optimum luminance; and modulating gray levels of input data of the display device based on a first gamma curve when the sensed level of external illuminance is equal to or lower than the predetermined illuminance, and modulating based on a second gamma curve when the sensed level of external illuminance is greater than the predetermined illuminance, wherein the first gamma curve includes a concave curve set in a low gray level area and a convex curve set in a high gray level area, and the concave curve and the convex curve are connected via an inflection point.

Abstract: A display device may include a display panel having subpixels, a controller configured to generate an output image frame based on moving a received input image frame for the subpixels according to time and to output the generated output image frame, and a panel driver configured to display the generated output image frame on the display panel. A movement order for the subpixels may be determined based on a movement direction and an arrangement of the subpixels disposed on the display panel. The subpixels may be utilized in outputting the generated output image frame to the display panel.
