4.8.4 Output Dithering
The Gamma LUT outputs a 10-bit value for each color channel. This value is dithered down to either 8-
bits for 24-bit per pixel panels, or 6-bits for 18-bit per pixel panels.
The benefit of dithering is that the eye tends to average neighboring pixels and a smooth image free of
contours is perceived. Dithering works by spreading the quantization error over neighboring pixels both
spatially and temporally. Two dithering algorithms are available: random or ordered dithering. Ordered
dithering is recommended when driving a 6-bit panel.
All gray scales are available on the panel output whether using 8-bit panel (dithering from 10 to 8 bits per
pixel) or using 6-bit panel (dithering from 10 down to 6 bits per pixel).
4.9 Four Channel LVDS Transmitter (for gmZAN3L Only)
The gmZAN3L implements the industry standard flexible four channel LVDS transmitter. The LVDS
transmitter can support the following:
Single pixel mode
24-bit panel mapping to the LVDS channels (see Table 14)
18-bit panel mapping to the LVDS channels (see Table 15)
Programmable channel swapping (the clocks are fixed)
Programmable channel polarity swapping
