Firstly, I'd like to say hello! Found these forms and they look rather interesting.
Anyway, on to the point. 😱
Ive been working on making my own custom LCD Display glasses a while... for three reasons realy.
1, I have a weird nose, and this way they'll actualy fit it.
2, I like doing random projects, a little beyond diy sometimes, but ^.^
3, The manufactured ones i can find, cost quite a bit... The Possibility of shaving some of this cost off sounds nice...
Regardless either way 1-2 stay... hehe.
Anyway what Ive been looking for, that i thought someone here likely could help with, is a lcd moduel sutible to my uses.
My needs, are something 4:3 that is 2.5-3.5" diagonal, appx, bigger than 3.5" wont work though, absolutely, preferibly 3" or maybe 3.2" ish.... I havent quite figured out 16:9 even though i would far prefur it, probobly a little bigger... but likely maxing out before 4" still.
One last thing i would like, is for them to be semi-translucent... ok so mostly i want to play with this.
See i have actualy attempted this once already, with a... about 2.3" lcd tv moduel... lower resolution than i would have prefured but sitting around in a barely functional portible tv.
Once i had removed it... i noticed this small plastic backing that was lose... after having removed it i realise, the moduel was semi-translucent, and could be seen through like a heavily tinted pair of sunglasses. Go figure. I devised a use of a pair of leds that allowed it to be backlit, and translucent at the same time, allowing me to veiw through, and on it. This worked great, infortunately in the assembly onto the frame i chose there was... substantal damage to the moduels connecting ribbons, on the moduels side, and due to its... intergrated design, cannot be repaired, totaling the attempt. Also it had a rediculously large pcb(due to having a tv tuner in it...) with a very short connecting cord, which resulted in this damage and a very heavy pair of sunglasses XD... i would like to avoid this as much as possible. Ugh that was a mouthfull. Sorry about that.
QVGA(320x240) would do, but QXGA(512x384) would be preferible. Yah i know not likely to find the latter... but would get much better results... And... as for the first... im sure it exists, just... suck at finding it. Oh right... in 16:9 the resolutions im looking for would be... QWXGA 640x360? urg guess its not as bad as it sounds XD... vert res is less than QXGA
(in this im using the Q designator as quarter... ive seen it used otherwise, so i noted this here...)
Id love to see super high res, yes i know the dot pitch will be insanely small, yet again, my eyesight is much better than the human norm...(im better than 20-20... yes such exists, requires a test at both distances to prove... messes with the rating system but anyway)
Basicaly, XGA/WXGA would be my dream(espeicaly WXGA) and would get more $$$ outa my bank account, though i figure is probobly unrealistic to expect... though seeing what was on www.displaytech.com maybe not as much so as i thought...
Anyway, on a sidenote.
This may seem a bit big for something on your face(and heavy...)... yes it is... i know its going to look a little odd, but first i intend to use large frames, and second i have a very wide range of normal vision... so likely many other people could have trouble with what im producing for my own use.
Anyway... any other comments/suggestions/ideas/ect are mostly welcome, though try to keep repeates to a minimum 😀
I now bring this court to order!
Ah er... sorry couldnt resist when i saw that smiley! 
P.S. Yes i did actualy search these forums for the info im asking for... i found lots of broken links and things taht wernt quite what i was looking for. Though i will continue searching, its alot to search through doing so in deep detail, i gave it more than just the basic once over already ^.^"

Pretty nice screens, but pretty expensive too and I'm not sure if you can clear everything out from behind them. If you send them an email you can get a full spec sheet on the LCD and dimensions for everything (I've got a couple for some of their 7 and 8" screen). I have seen them sold elsewhere under the name Accele (their parent company), but I think the pricing was about the same.
If you're in the mood to take something apart, you could try any of the smaller Lilliput screens (search on ebay for them). Another thing I came across was mini portable DVD players/TVs made by Coby. I looked through their site (www.cobyusa.com), but unfortunetly they don't have a whole lot of information on them and the pictures of the screens themselves are clearly mock-ups. A couple of them do say they have A/V inputs, but of course you're still taking the chance of being stuck with the entire circuit board if you can't seperate the LCD control portion.
Anyways, good luck with the goggles. I've been considering trying to build a pair for myself, but have yet to come up with a reason to justify doing it 🙂.

this is the craziest mod i've ever heard of.
so crazy that it's cool..............
go for it man.............. go for it.

Instead of a heavy flat lcd infront of your eyes,
How about you do the old mission impossible glasses.
Small screen projector focused onto a fiber optic cable, or bundle of cable. Routed from anywhere you want to an ordinary pair of goodlooking sunglasses. Then you refocus the immage onto the backside of the glasses using one really tiny lens. Mirrored work great. cord buldle will be small and apx the size of the safety string.
Card sharks and the movies have used these for years. Military hud displays use a pieces of flat glass in front of your eyes with that exact. Still the same concept with see through projection onto ordinary mirrored glasses.

These mysterious screens you seek are all over the place! 🙂 PDAs and digital cameras and cell phones have exactly what you are looking for. Cheap? Maybe if you could find a broken one with the LCD in tact. The only thing with these is you might have to design an interface to the LCD. These would be proprietary I'm sure. Beyond that, it's pretty simple. Power the LCD, interface to it, mount it. You're good to begin!
Now I'm not sure if just displaying two identical screens to each eye would give you the illusion of a 12 ft screen from 12ft away. You might have to do some funky changes to the picture to make it look right. Good luck!
