  • Method for driving organic light emitting display device with a gamma voltage generator
    Patent number: 8917295
    Abstract: A display device, such as a OLED device, and a method of driving the OLED device. The display device includes a gamma voltage generator that generates sequentially decreasing gamma voltages based on sequentially decreasing reference voltages. A data driver selects a gamma voltage from the gamma voltages for driving a pixel based on digital data indicative of a gray scale level for the pixel. In one embodiment the gamma voltage generator includes a resistor string and an input tab that is electrically isolated from the resistor string.
