ABSTRACT:
A system and method for reducing the phase difference between adjacent gray scale values employ compound data words. The compound data words include a first group of data bits and a second group of data bits. A display driver circuit is configured to provide display control signals causing each bit of the first group of data bits to be asserted on the display pixel for a coequal time period, and causing each bit of the second group of data bits to be asserted on the display pixel for a time period dependent on an associated significance of each bit. Optionally, the display driver circuit further includes a compound data generator configured to provide the compound data words. A method for asserting a compound data word on a display pixel includes the steps of asserting each bit of the first group of bits on the display pixel for a coequal time period, and asserting each bit of the second group of bits on the display pixel for a time period dependent on an associated significance of each bit.
