SYSTEM AND METHOD FOR USING COMPOUND DATA WORDS TO REDUCE THE DATA PHASE DIFFERENCE BETWEEN ADJACENT PIXEL ELECTRODES

摘要

A system (900) and method (1500) for reducing the phase difference between adjacent gray scale values employ compound data words (504). The compound data words (504) include a first group of data bits (EB3-EB1) and a second group of data bits (B5-B0). A display driver circuit (900) is configured to provide display control signals causing each bit of the first group of data bits (EB3EB1) to be asserted on the display pixel for a coequal time period, and causing each bit of the second group of data bits (B5-B0) to be asserted on the display pixel for a time period dependent on an associated significance of each bit. Optionally, the display driver circuit (900) further includes a compound data generator (902) configured to provide the compound data words (504). 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.
