Oki starts volume shipments for large-size LCD TV-use driver LSIs
<http://www.digitimes.com/displays/a20050214PR200.html>

"Oki's new chip, the ML9156, has a 10-bit input with
a one billion-color display, ..."

ok

"... which offers picture quality up to 60 times
higher than other chips."

That's reaching a bit, but at least panels using this
driver might have a chance at properly tracking a
gray scale.

An exercise in futility - the cell to cell variation in panels is not
nearly THAT small,
so it's just an attempt to play the old numbers game. Variations in filter
deposition
and discrimination ratio can not be further improved without adding lots of
cost to
the panel mfg. process, and right now the cost is perceived as still too
high.
This is very similar to the issue of variations in cut-off and gamma between
the RGB
guns of a CRT affecting their ability to accurately display colors between
monitors.

Most panels can not do 6-bit drivers full justice - and 8-bit drivers are
just now
becoming more common (at a higher cost, of course). Lowest cost panels will
stay
with 6-bit drivers and FRD the other 2 bits until the cost of 8-bit drivers
comes down
to an equal point of 6-bit ones.
