Abstract:
In a liquid crystal display (LCD) driver circuit, harmonizing a pixel inversion pattern and a dither pattern is disclosed. The pixel inversion pattern and the cooperating dither pattern interact with each other in such a way that there is substantially no discernable video artifacts generated. The cooperating dither pattern can be selected from a plurality of dither patterns using a programmable dither block.
