RED/GREEN/BLUE GRAY SCALE VOLTAGE GENERATOR AND LIGHT EMITTING DISPLAY USING THE SAME

摘要

The present invention provides a generation device for generating gamma-corrected gradation voltages for R, G, and B so as to have an optimal display characteristic based on display characteristics of the display panel.;The RGB gray scale voltage generation device according to the present invention, based on the display characteristics of the display panel, R gamma correction unit for outputting red (R) gamma correction data, green (G) gamma correction data and blue (B) gamma correction data, respectively This includes the G-Gamma Government and the B-Gamma Government. And an RGB gamma selector for selectively outputting any one of gamma correction data output from the R gamma correction unit, the G gamma correction unit, and the B gamma correction unit, respectively. A plurality of intermediate voltages present between the voltages are output based on the gamma correction data output from the RGB gamma selector. Then, the highest voltage, the lowest voltage, and the plurality of intermediate voltages are input, and the gray level voltages are output based on the voltages.
