Abstract: A luminance compensating apparatus includes: a color coordinate data receiver; a white luminance data receiver; a luminance divider to divide a first luminance of a first display module from first color coordinate data and first white luminance data, and to divide a second luminance of a second display module from second color coordinate data and second white luminance data; a luminance rate calculator to calculate a rate of the second luminance compared to the first luminance to output a first luminance rate; a target luminance calculator to divide the second luminance by the first luminance rate to output a first target luminance of the second display module; and a luminance compensator to output first luminance compensating data for compensating the second luminance of the second display module from the first target luminance.

Abstract: An organic light emitting display device includes a display panel, a scan driver, a data driver, a power supply which provides a first voltage to a first power terminal of the pixel and selectively provides the first voltage or a second voltage to a second power terminal of the pixel, and a controller which selects one of a normal driving mode and a power saving mode as a panel driving mode where the power supply provides the second voltage to the second power terminal of the pixel in a first period of one frame period and provides the first voltage to the second power terminal of the pixel in a second period of one frame period when the panel driving mode is the power saving mode.

Abstract: A gamma voltage generator includes a reference gamma selector, a reference gamma converter, and a gamma curve adjuster. The reference gamma selector selects a top reference gamma voltage and a bottom reference gamma voltage that are between first and second reference voltages. The reference gamma converter converts the bottom reference gamma voltage to a conversion reference gamma voltage based on the top reference gamma voltage. The gamma curve adjuster generates a plurality of grayscale gamma voltages based on the conversion reference gamma voltage and the top reference gamma voltage.
