Abstract
A gamma setting pattern of an organic light emitting display device and a gamma setting method using the same, which can be applied to even a small screen and improve accuracy of gamma setting. The gamma setting pattern includes a grayscale display region and a circumference pattern. The grayscale display region is disposed at the center of a screen, and emits light corresponding to one of a plurality of predetermined grayscale values for setting a gamma value. The circumference pattern is disposed at the circumference of the grayscale display region, and has luminance varied corresponding to the grayscale displayed in the grayscale display region and a predetermined panel current amount.

A gamma setting pattern of an organic light emitting display device, comprising:
- a grayscale display region disposed at a center of a screen, and emitting light corresponding to one of a plurality of predetermined grayscale values for setting a gamma value;
- and
- a circumference pattern disposed at the circumference of the grayscale display region, and having luminance varied corresponding to the grayscale displayed in the grayscale display region and a predetermined panel current amount.
A gamma setting method of an organic light emitting display device, comprising:
- sequentially displaying grayscales respectively corresponding to a plurality of predetermined grayscale values on a screen of the organic emitting display device;
- and
- setting a gamma value by detecting the luminance of a region in which each grayscale is displayed,
- wherein a grayscale corresponding to one of the plurality of grayscale values is display in a grayscale display region disposed at a center of the screen, and the luminance of a circumference pattern disposed at the circumference of the grayscale display region is varied corresponding to a predetermined panel current amount.
