    Abstract: A method is provided that allows the use of monochrome PMOLED display driver to generate grayscale patterns without the need to change the resolution of the 1-bit digital-to-analog converter (DAC) on the data line (SEG). The method further allows the elimination of extra frame buffer display memory needed by conventional techniques. This is achieved by swapping display memory space for display image pixel color (grayscale) depth in the expense of display resolution. The method further allows grayscale pattern data to be written into frame buffer only once without additional control from the host controller. The method further allows the dynamic application of grayscale on selectable whole or portion of a scan line such that full grayscale image display or a mixture of monochrome and grayscale image display in a single display panel is possible.
