A Reconfigurable, Low Power, Temperature Compensated IC for 8-segment Gamma Correction Curve in TFT, OLED and PDP Displays

In the market sector of consumer products based on TFT, OLED, PDP, and other displays, there is a demand for the capability of driving different displays by means of different gamma curves with the same driver circuit. Therefore, the display driver must have a built-in reconfigurable gamma correction circuitry able to correct the gamma curve of different types of displays. The presented solution proposes a reconfigurable gamma correction circuitry having high accuracy in the generated voltage levels and high flexibility in producing gamma correction curves. The configuration circuitry is digitally temperature compensated and the whole IC has low power consumption with respect to the target product sector.
