VFD Displays

Well, I am looking for a graphics display with high visibility about 120x60 pixels size, two color.

I have found the VFD displays that seem to be perfect for my application, but I·a wonder if·these displays are·suitable for battery operated devices ? It seems by specificactions that take lots·of power!

Any suggestion for a high-visibility, battery operated,·display other than VFDs? I have found also the color transflective TFTs but these are *very* expensive.

For high-visibility I mean: visible under any light condition and type(for example, in the darkness, with tungsten bulbs,·as well as under direct·Sun light)·and with a reasonable view angle. If it is possible to control brightness it would be better (VFDs allow for this too).

    I have been recently using the Noritake Displays...I have both a 112X16 and a 140X32 but they have larger ones available.· Even the 112X16 uses 250+mA though so battery power is not viable option.

    I guess it depends on the size of the battery. 7.2V 3300 mAh NiMH RC battery packs are commonly available for $20-$30 and will power the display Chris mentioned for 13 hours.

    Two color?

    STN-type (Super Twisted Nemitic) LCDs are pretty darned good, they have viewing angles much better than the TN-type, and they're available with LED backlights.· They're the sort with the irridescent back that they've started using·in watches now, too.· A contrast knob would top it off nicely.
