Abstract
A system and method for driving a display region on the display are described. The method includes receiving a desired color for a pixel, determining a waveform to drive the pixel to desired color, updating frame buffer with an index to the determined waveform, updating waveform table with the determined waveform, and then driving the pixel on the display using the index and associated waveform. After the drive, the waveform is removed from the waveform table and the corresponding pixel in frame buffer is updated with an index corresponding to a null waveform.
