Classification: CPC G | IPC G

Claim 1:
2. A display device comprising:
a plurality of pixels configured to display an image having an on-pixel ratio;
a user interface configured to manually set an input maximum luminance; and
a grayscale converter configured to:
calculate first compensation offsets based on positions of the pixels and input grayscales for the pixels;
convert the first compensation offsets into second compensation offsets according to a maximum luminance weight based on the input maximum luminance; and
calculate converted grayscales by applying the second compensation offsets to the input grayscales,

wherein, when the input maximum luminance is set smaller than a first threshold value, the image has a uniform maximum luminance, even when the on-pixel ratio is changed, and
wherein, when the input maximum luminance is set greater than the first threshold value, the image has various maximum luminances according to the on-pixel ratio.
