Abstract
This invention is related to an automatic Gamma correction system in which a novel display driving circuitry is designed with a digital/analog converter (DAC), wherein the Gamma reference voltages as well as the corresponding gray-scale values are adjustable. Therefore, the present invention provides a greater degree of freedom for the realization of the correction of Gamma parameters so as to fit the curve representing the transfer function of the destination gray-scale values and the voltages required by the display driving circuitry.
