Check it out in the Hacker's section of the web > site. I already ordered one of these displays. Infact.. I have it sitting right in front of me. You can get full docs on how the display works here: http://www.sel.sony.com/semi/PDF/LCX005BKB.pdf I don't think it will be too dificult.. I will be trying to breadboard a driver for it in the next couple of weeks. (First attempt at this type of thing.. should be lots of fun.. :) I am also hoping to make some kind of backlight/reflective/semi-tranparent HMD with it. Acording to the specs, it does have drivers.. all the interface would need to provide is RGB and several clocking signals.. BTW - Sony explicity says that ANY lcd used in and HMD is not supported. Sony does have a driver chip for it that will take NTSC/PAL directly and drive the display. I've been unable to find this chip. (Still have a couple of other places to look..) This would be by far the eaisest way of driving the display. This brought up a good idea.. what about the $70-150 portable TV's out there.. it should be possible (with some ripping apart) to adapt one of these to an HMD?? I've not had the time to run out and look at some of them. Tom
