is there a square lcd (liquid crystal display) or oled (organic light emitting diode) thats 2.5 x 2.5 inches - 4.0 x 4.0 inches? please help, ive been looking for like a month now and i cant find one.
Hmm, that’s going to be a rare beast - high res screens are nearly all VGA or relatives which are all rectangular. Some small mobile phone screens are square, but I think they don’t go beyond about 40mm square.
Is there a reason you can’t use a VGA size and hide the ends of the screen, just using the middle square?
Don’t know what res or color option you are looking for. Have a preference?
If you're looking for mono and 160x160 is ok, you could look at this: http://www.crystalfontz.com/product/CFAG160160B-TMI-VZ
If you're looking for color, you're not likely to find it without hacking it up.
If you want to try your hand at hacking and a monochrome screen, some progress has been made on old PalmPilot screens: http://www.chiefdelphi.com/forums/showthread.php?t=79101 Not sure the size on those...
For searches, google 120x120, 160x160, 320x320 (plus LCD or OLED) and remember that the higher you go, the more ram you're going to chew up buffering the screen no matter HOW hacky you get.
okay, well that helps... thanks alot!
