the only chip i know is the m7220 which is a graphics chip which may be used
in parallel to provide grey/color processing.  each chip can handle 4
bits at a time i believe so you could get 8 color + intensity or so on
one chip or 16 levels of gray.  if you used 3 of them that sounds like
a purty good like chip.  anyway, it draws vectors, arcs, and has the hooks
for zoom and pan.  it will handle ~1k by 1k and even sortof characters.  it
also has 2 windows i believe for scroling/zooming,  there is a reasonably
good application note from nec.  intel is also making it, along with
a high powered (for intel) text processing display chip...
  cheers,
