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.

Abstract: An apparatus for depositing an organic material and a depositing method thereof, wherein a deposition process is performed with respect to a second substrate while transfer and alignment processes are performed with respect to a first substrate in a chamber, so that loss of an organic material wasted in the transfer and alignment processes can be reduced, thereby maximizing material efficiency and minimizing a processing tack time. The apparatus includes a chamber having an interior divided into a first substrate deposition area and a second substrate deposition area, an organic material deposition source transferred to within ones of the first and second substrate deposition areas to spray particles of an organic material onto respective ones of first and second substrates and a first transferring unit to rotate the organic material deposition source in a first direction from one of the first and second substrate deposition areas to an other of the first and second substrate deposition areas.

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.
