An organic light emitting diode display including: a plurality of pixels on a substrate; an encapsulation substrate facing the substrate; a color filter on one surface of the encapsulation substrate facing the substrate and including a red filter, a green filter, and a blue filter; and an overcoat layer including a first region covering the red filter, a second region covering the green filter, and a third region covering the blue filter. At least one of the first region, the second region, and the third region has an optimized refractive index and/or an optimized thickness.
Abstract:
A display device includes a display part, a degradation compensator that generates a first compensated grayscale value by compensating for a first grayscale value corresponding to a first pixel, and generates a second compensated grayscale value by compensating for a second grayscale value corresponding to a second pixel, and a data driver that generates a first data signal based on the first compensated grayscale value to supply the first data signal to the first pixel, and generates a second data signal based on the second compensated grayscale value to supply the second data signal to the second pixel. A second degradation curve is defined by a first degradation coefficient corresponding to a first degradation curve, and a second degradation coefficient corresponding to a first estimated degradation curve for the light conversion particles of a second color calculated by applying the first degradation curve.
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.

A display device is disclosed. In one embodiment, the display device includes a first conversion unit receiving gray data and outputting a gray data value of a second gamma curve, which has a luminance equal to a luminance of the gray data on a first gamma curve.
