From a quick look at the datasheet, it seems like it should work. There
are a few potential issues that I could see coming up:
- it is a 5V module, and Vih is put at 0.7Vcc, which at 5V would be
3.5V. So in other words the signals coming from the gumstix won't be
recognized since they are 0-3.3V at best. The min Vcc is put at 4.5V
though, so it is possible you could power it at 4.5 or 4.6, which would
make the Vih around 3.2V. If you are lucky, this may work. The standard
solution to this would be to add level translation for the 20 or so
incoming signals, but that would be a lot more work, especially since it
may need to be put on a PC board to cope with the speed of running an
SVGA 16bpp panel at 60 or so Hz. I wouldn't be surprised if you had
signal integrity issues if the level shifters and interface were wired
up with a forrest of wires and DIP packaged chips on vectorboard. But
I'd give that at least even odds of working.
- it is an 18 bit color module; gumstix only puts out 16 bits. So just
drop two LSBs on the panel; no big deal.
- it seems to have no backlight, and is intended for use in projection
systems. This may be what you want, but on the other hand I can imagine
that feature making the panel pretty much useless for a wide variety of
ordinary uses. If you put a transmissive LCD into a tablet case for
instance, with no backlight, it would look black all the time.
