see this Kodak news release Looks like it's better to wait for those than for faster LCD's for page-flipped desktop flat panel displays ? | ||

Hi, I am modestly familiar with EK's OLED technology. I am unfamiliar with "page-flipped" FPDs. Could you please clarify what you are referring to? | ||

Sorry for being a little in a hurry. With everything I had in mind, but omitted, put back in, it should have read something like: 'desktop flat-panel displays capable of properly displaying page-flipped stereo video signals for use with shutter glasses' | ||

Andreas, In advance, I have to appologize for my limited knowledge of headset technology. I only check into this board to see what people here are saying about OLEDs. I am an investor in OLED technology stocks, and know a little bit about both OLED technology and marketplace projections for deployment of OLEDs. Because of sparse knowledge of stereo 3d headset technology, I dont know if I quite understand the requirements of "page-flipped stereo video signals for use with shutter glasses" Presently, there are many uncertainties in OLEDs, and I would factor these into any buying decision you might have. The EK/Sanyo display that you reference is quite credible and has its merits, however is not likely to be a viable competitor in the marketplace. The pluses of this display are that it is a small molecule active matrix display. I believe that this technology will win the OLED display market. This display has a big disadvantage in that it presumably uses a white-light emitting OLED with color filters, which is grossly inefficient. The OLED displays of the future will incorporate OLED emission in the red, blue and green wavelengths of light without color filters for greater efficiency. Also, the white light emission uses EKs fluorescent, singlet emission, which is not as bright as the emissions one would get from triplet phosphoresent emissions that Sony and Samsung are working on. To me, I see this display as EKs way of raising the white-flag (no pun intended). As for OLED technology, most projections show initial deployment of AM OLEDs will during 2003 in small display applications in Asia (where wireless networking and cultural appeal are stronger), in applications such as cell phones and PDAs. If we are lucky, we might see small screen (<8") by the end of next year, but I would not rush to buy one. There are still a lot of bugs to work out, particularly with durability, lifetimes, and color purity. I am hopeful that the market will accelerate by 2005, with applications for displays as large as monitors... and who knows what lies beyond that. If I havent provided an answer to your question, I appologize, but I really dont understand the requirements of "page-flipped stereo video signals for use with shutter glasses". I hope this helps. Best Regards, I_S | ||

Well, I'm not going to buy anything soon, neither OLED stocks nor displays, and I also know that a 15" prototype doesn't mean that we will have 40" OLED TV for 100$ next Xmas ;-) For the problems of stereoscopic vision (maybe you should occasionally read Christoph's excellent page about stereoscopy basics on this server), I just see OLEDs as a possible solution from two sides: a) tiny (and hopefully cheaper) hi-res displays for HMDs, to provide a separate display for each eye's image and allow stereoscopic vision, b) large, flat desktop monitors (the 15" Kodak/Sanyo being a promising start), with either - auto-stereoscopy add-on optics, as already done with some TFT displays (similar to those 3D-pictures you find on postcards or in cereal boxes) or - since OLED's response times are neglectible, compared to LCDs and CRT phosphors, they would be ideal for high frame rates of >120Hz, which would allow to view a time-sequential stereoscopic signal (i.e. where the even frames show the pictures for one eye and the odd frames those for the other eye) with virtually no flicker (due to the high refresh rate) and no ghosting (cross-talk between left and right eye's images, at least the major part caused by display latency). Agreed that there still seem to be some problems to cope with, especially lifetime, but maybe they can make the displays so cheap and easily replacable that you can swap them like lightbulbs some day ? |
