Patent ID: 8525762

Claim:
A method of adjusting white point display parameters of an active matrix organic light emitting diode (AMOLED) panel, the method comprising: obtaining an adjusted Gamma curve for all subpixels of all pixels of the AMOLED panel, wherein the adjusted Gamma curve for the subpixels of all pixels of the AMOLED panel is determined according to a white-point adjustment; storing the adjusted Gamma curve in a non-volatile memory; controlling a switch enable register to operate a first switch to load the adjusted Gamma curve for the subpixels of pixels of the AMOLED panel into the non-volatile memory, and upon completion of loading the adjusted Gamma curve for the subpixels of pixels of the AMOLED panel into the non-volatile memory, operating a second switch in order to load the adjusted Gamma curve stored in the non-volatile memory into a static register memory during normal operation of the AMOLED panel, the second switch having a first end directly connected to the non-volatile memory and a second end directly connected to the static register memory; and utilizing the adjusted Gamma curve loaded in the static register memory to drive the AMOLED panel to have optimum color properties while displaying image data.
