Abstract: A method of generating compensation data in a display device includes setting a pixel group including a first target pixel and first non-target pixels adjacent to the first target pixel among a plurality of pixels of a display panel; switching on the first target pixel and switching off the first non-target pixels to generate a first captured image and store the first captured image; switching on the first target pixel and the first non-target pixels to generate a second captured image and store the second captured image; switching off the first target pixel and switching on the first non-target pixels to generate a third captured image and store the third captured image; and calculating luminance correction data of the first target pixel based on the stored first to third captured images.

Abstract: An optical compensation device includes a luminance measurer that measures display luminance of a display device including a plurality of areas. A gamma corrector corrects a gamma voltage so that a first area of the plurality of areas has a gamma characteristic corresponding to a target gamma value based on the display luminance, and calculates a gamma value for each of the plurality of areas based on the display luminance. An optical compensator calculates a compensation parameter for each grayscale based on the display luminance and the gamma value. A luminance deviation for each of plurality of areas of the display device is compensated based on the compensation parameter.

Abstract: A head mounted display device includes a display unit divided into at least one first area and at least one second area, a lens unit which supplies an image displayed on the display unit to a user, and a frame which fixes the display unit and the lens unit thereto. The display unit includes a memory which stores first compensation data corresponding to the first area and second compensation data corresponding to the second area, and a position determiner which determines whether first data supplied from an outside belong to the first area or the second area.
