It is possible that i may gain use of this QVGA screen i pulled from a Compaq Ipaq?
Not sure if you're joking or not...
In theory you could, but you would only be able to wire maybe 3 bits per color; maybe leaving enough digital I/O lines left over for the control - and I am not sure if you could drive it fast enough so that it didn't flicker like a banshee.
They talk about the module having a 4 bit interface (4 line?), but then go on and talk about the panel interface; I can't tell if there is a driver chipset on the module or not (if there is, and you can figure out how to hook it up and what the control codes are, you're mostly there).
Also, the big issue on these kinds of panels (really, any of the small consumer junk that clutters our lives with small screens) is the fine pitch connectors; while Digikey or Mouser may have them, they may not, depending on a host of reasons.
I for one am looking for a Mini-USB expanded male connector (with the lines for mic and left/right headphones) to interface with my G1 phone; unfortunately, it looks like you can only get such multi-pin connectors from ??? (who knows) - right now, my only option is to get a cheapo headset for the G1 and cut the cord off.
I have this weird idea of interfacing an Arduino via audio I/O (using some form of FSK audio for data i/o - I have yet to find a way to use the USB port of the G1 in Android, so even if I set up a USB Host shield on the Arduino, I still couldn't do anything)...
