Fraunhofer IPMS are showing an OLED based pico projector at SID. The projector is based on an OLED microdisplay by the Hypoled project.
The prototype projector is 25mm long, 18mm diameter, quite small (although not the smallest pico projector module). The OLED is currently monochrome only. The brightness is 10,000 candelas per square meter (a color OLED will be about half).
Corning is showing their latest Silicon-On-Glass (SiOG) technology. SiOG is used to transfer a thin-film of silicon into a display substrate. SiOG is scalable, and currently Corning can make it on a Gen2 substrate, Gen4 by the end of the year.
Corning SiOG prototypeThe SiOG process would permit the fabrication of stable OLED pixel switches with higher yield and much greater performance than LTPS, and on larger substrates. Corning claims that costs will be lower, because this enables manufacturers to integrate the circuitry on the display substrate easily.
Some panel makers are already trying this out, and hopefully we'll see prototype OLED displays based on SiOG by the end of 2009.
Universal Display and Samsung Mobile Displays present advances in green Phosphorescent OLEDs at SID. This new material will be used in both hand-held devices and OLED TVs, extending lifetime and efficiency. UDC's red materials are already used in Samsung's AMOLED displays, and it's likely that we'll see Samsung use their green materials as well.
The companies showed a highly-efficient, green
UniversalPHOLED material that has been used in a top-emission PHOLED
device architecture. Using this approach, they achieved two
milestones. A green PHOLED with NTSC color at CIE(0.20, 0.73), high
luminous efficiency of 110 candelas per Ampere (cd/A), and a low voltage
of 3.6 V at 3,000 candelas per square meter (cd/m2) was
achieved.
A second device structure using this green PHOLED material
system also achieved an ultra-high luminous efficiency of 160 cd/A along
with CIE(0.28, 0.69) and low voltage of 3.8 V at 3,000 cd/m2.
These compare to a standard bottom-emission device with CIE(0.33, 0.62)
and 52 cd/A using this same green PHOLED material system. Replacing the
green fluorescent OLED material typically used today in an AMOLED with
this new green PHOLED can result in a significant 37% power savings.
The operational lifetime for this green PHOLED material system is also
very good. A bottom-emission device using this material system offers >
300,000 hours to 50% (extrapolated) and 15,000 hours to 90% of the
initial luminance of 1000 cd/m2 (defined as LT90). With these
top-emission devices, the LT90 lifetime is 28,000 hours and 6,400 hours,
respectively, for the 110 cd/A and 160 cd/A devices.
The Fraunhofer institute shows their "Interactive Data Eyeglasses". These glasses include an OLED microdisplay on a CMOS chip that also includes an eye tracker .
The chips (which is 19.3 by 17 mm) is fitted behind the hinge on the temple. The image is then projected onto the retina of the user. The OLED have been chosen because they needed high luminance.
Kodak has kindly sent us a new video showing their new OLED lighting panels (preceded by some Kodak 'ads'). Kodak are still working on the technical issues of their OLEDs, but they are also seeking potential collaboration with other companies to bring these to market.
Just a few days ago Kodak received a 1.7M$ project from the US Department of Energy to develop OLED lighting - 15cmx15cm panels with over 50lm/W efficiency and over 20,000h lifetime.
Toshiba Mobile Displays (TMD) shows a new 4.15" AMOLED display. The panel has a 60,000 hours at 200cd/M2. The display uses small molecule OLEDs with a top-emission structure. There's no word when such panels will be available...
We also hoped to hear more of TMDisplay's OLED TV program (TMDisplay are working towards HDTVs together with Panasonic), but I guess we'll have to wait some more...
A short clip by CBS showing the 'TV of the future' - OLEDs. Some nice new footage of OLED displays and TVs, flexible and transparent OLEDs, as well as an interview with Janice Mahone from Universal Display.
3DIcon filed a patent for a high-resolution projection screen that could replace current cinema and other existing reflective display screens.
Their idea uses an OLED display driven by any front projection system to produce high-image-reproduction quality, brightness under ambient light with high contrast, and exceptional color fidelity.
Some interesting E Ink related news today:
Amazon announced that the Kindle DX will be released on June 10th. The DX has got a 9.7" 1200x824 (at 150 ppi) E Ink display, with 16 shades of gray. It costs 489$, you can pre-order now.
Amazon Kindle DXThe DX weights 535grams, and the size is 10.4" x 7.2" x 0.38". It's got 4GB of internal memory (around 3.3Gb of which are available to the user). The modem is a EVDO 1xRTT (Sprint 3G). It supports many formats, including PDF.
Prime View (PVI) announced that they will acquire E Ink for 215$. PVI is the largest ePaper display maker, it will be interesting to see how they integrate E Ink (which is more of an IP company).
There are some sketchy details on the new Samsung SCH-W780 phone. Apparently it's got a 8Mp camera, supports TDMB and has a 2.8" WQVGA AMOLED display. It should be out in June, and will cost 870,000Won (around 700$). The phone actually looks like the S8300 ultra touch phone, so it might be just a Korean release of the same hardware.
