I'm not too familiar with OLED and haven't the foggiest if these panels are transmissive at all, but I think I'm gonna try and get my hands on one of these things:

Obviously these kits are designed for product manufacturers who utilize small TFT LCDs and might be interested in replacing them with the OLED technology, not DIYers looking for a free lunch. Nonetheless, if this display lets enough light through this kit contains almost all the makings for a really small and spiffy projector, and if the display is opaque well I guess it gets used for some as-yet-undetermined project. 😉

Not yet, although judging by the cost of 2" QVGA and above LCDs, probably astronomical. 🙂 Then again, OLED panels are already being used in cellphone and car stereo displays (though lower resolution versions I'm sure) so who knows. I'll reply when I hear back from Kodak though.
So has anyone ever gotten a close enough look at an OLED panel (or done enough research.. I'm gonna look into this more later but I'm "working" at the moment) to know if there are any transmissive/transparent qualities to them? Since they are "self-backlit" by being highly reflective, my instinct tells me no, but I'm trying to be optimistic.. =)
OLED stands for Organic Light Emitting Diode. Yes, LED. They are not "Backlit". Each pixel generates its own light- enough for direct view, but not nearly enough for projection.
OLED displays offer the possibility of replacing projection displays because the expected cost to manufacture them in large panels is very low (they are plastic, after all). The expected low cost is at least a few years away.
If the reality lives up to the hype, OLED displays will be covering our walls in a few years. Projectors will be viewed as quaint relics, the same way we look at round B&W CRT televisions now.

I understand they are not backlit, hence my words "they are basically self-backlit", which were intended to mean "They emit enough light on their own that additional backlighting is not necessary." Guess I should have chosen my words more carefully.
You are absolutely correct. What I was asking is if the display is transparent enough to allow additional backlighting through it, or if the back of the LED panel is opaque/non-removable.

I don't think it would help you much even if they were totally transparent and you could pump a lot of light through because that additional light has to be controllable.
With an LCD, each picture element acts in a similar manner as a shutter. Each one opens and closes to let more or less light and colour through to make up a viewable picture.
With the OLED (organic led) the picture elements are like tiny led that glow according to picture information.
There is nothing in them that can modulate a strong light source.

I'm still interested, if you get a price by all means please let me know. I have other "projects" in mind 😉

I would say about $5,000+ for that setup. People in the forum did contact a maker of super high res lcds that size, and they were the cost of a nice projector. This is new technology OLED, so guess what? Higher price. Mabey in ten years. 🙁 Did you contact kodak?
I have a feeling it might be less, it's new technology.
With the release of new gear sometimes you can luck out and get in on the evaluation stages while the market developes. I've read that the industry figures on a 20 percent cost reduction vs LCD once full scale production starts. Seems to me they might be breeding a market. They are offering evaluation kits so it might be restricted to developers and OEM's (they might be looking for BIG players...GM Motorolla...you know the guys..).
And even if it does go less than 5 grand it would have to go for a bunch less before it would be worth it for my application. I'm still interested though, has anyone read anything about their performance in strong ambient light? Watchabillity in sunlight specifically. I did a quick search and was overwhelmed with OLED "news flash's" but havent found a decent review about the panel itself, only what it is going to do for the industry.

Well that is a ballpark estamite... So how does this screen work? Uses arrays of tiny RG&B leds to make a picture... sound like it may be a pain to project the standard way... mabey the leds could be bright enough to project a good image... Who knows... I guess it would have no backlight involve... Sorry if i sound repeditive, i didn't read the website in depth.
Oh I think that given the method of image production it wont be suitable for projection (as I understand it anyhow). Someone I know just might qualify as "one of the big guys" in the near future, and I'd like to have some info for him.

Well if the leds are bright enough to cast a good image (which i suspect they will be, we're golden. But i do not plan to buy one of these in the next 10 years when they would probably be widely used, and by then i hope to get a real crt projector.

John, cost for the evaluation kit is $5200. If you will either contact me at the enclosed phone number or send me your contact information, I will be more than happy to discuss the details of the kit.

Ugh. So much for having this to play with anytime in the next few years..
