OLED TVs; Transparent, Flexible, Touch, and High Resolution Displays; New Lighting Products; a-Si and Single-Crystal Silicon Substrates Highlight Display Week
June 8, 2009
AUSTIN, Tex., June 8, 2009 — OLEDs permeated the Society for Information Display’s 2009 International Symposium, Seminar, and Exhibition in San Antonio last week. The growth and influence of organic lights-emitting diodes was clear both on the exhibition floor, with numerous display and lighting products and prototyes, and in the sessions, with 87 technical papers, many in the category of invited with special awards. The poster session added 39 OLED presentations.
“Although the event was down in numbers of both attendees and exhibits, the OLED community is quite optimistic with a record number of displays and lighting devices in numerous exhibits,” said Barry Young, Managing Director, OLED Association. “In all, the future of OLED technology appears stronger than ever.”
Association members, eMagin, Corning, Ignis Innovation, Kodak, Novaled AG, Samsung Mobile Display (SMD), and Universal Display Corporation (UDC) showed a wide range of state-of-the-art products.
• eMagin – the leader in near eye displays showed the industries highest resolution and pixel density
o 0.44-inch SVGA 3DS 800 x 600 x RGB white plus CFA; 11 µm pixels
o 0.61-inch SVGA+ 852 x 600x RGB white plus CFA
o 0.77-inch SXGA 1280 x 1024 x RGB white plus CFA achieving 90% NTSC with 1000:1 CR
• Corning – Showed their glass substrates using single crystal silicon that enables manufacturers to get the benefits of high mobility, uniformity and reliability, which they believe will significantly increase performance and yields while reducing system cost.
• Ignis Innovation – Demonstrated the use of amorphous-silicon (A-Si)backplanes and voltage compensation, TFT compensation, and efficiency compensation as a backplane for AMOLED displays
o 2.2-inch 320x240, 200 cd/m2, 100K:1, 50,000 hr
o 4.8-inch quad RGBW, 288x154, 500 cd/m2, 100K:1, 75,000 hr; same dot-pitch as 32-inch LCD
• Kodak – showed a new innovation in lighting control, which allows light to be directed at a 90° angle to increase brightness in high ambient conditions
o 6-inch lighting panels featuring color rendering >85%
o 5-inch RGBW display, with sRGB blue, 380 cd/m2 peak illumination, 370-µm pitch
• Novaled, AG – showed their latest results PIN OLED® technology and Thin Film Encapsulation of OLEDs, yield improvement for singlet and triplet emitters with lifetimes up to 110 thousand hours at efficiencies up to 50 lm/W as used in lighting applications.
• Universal Display Corporation – showed their phosphorescent technology
o 4-inch flexible monochrome on metal substrate, 320 x 240, 100 cd/m2 at full white, 1000:1, 0.3 mm thick
o 2-inch sample lighting panels in red, green blue and white
• Samsung Mobile Display (SMD) – showed a wide range of AMOLED displays including transparent, flexible, curved and touch capabilities as shown in the next Table. Highlighting the demonstration was 14.1-inch and 31-inch TVs.The full range of Samsung’s OLED display offerings is summarized in the following table.

The Seminar also featured exhibits by a number of other OLED companies, including LG Displays, which showed 15- and 19-inch panels; Merck showing Merck-DELO encapsulation proven in tests at 85ºC/85%RH for 1000 hr; OLED materials for solution and vapor deposition; SAES, which makes getters for flexible OLED manufacture with newly developed transparent layer that can be applied through UV or thermal curing; Add-Vision, demonstrating printed flexible monochrome OLED displays and lighting, using a low-cost manufacturing process readily scalable to production levels; Fraunhofer, showing 320 x 240 monochrome bidirectional OLED microdisplay with a 4 x 3 array of photodiodes for imaging eye position: Aixtron, which has OVPD implemented up to Gen 2 and up to Gen 3.5 (650 x 780 mm), with an approach that provides 60% materials utilization; SimTec, demonstrating their SimOLED simulation software for LED design; Daou Xilicon, which offers OLED manufacturing simulation, including mask editor, structure generation, and optical simulation; and Sunic, featuring thermal deposition equipment that supports substrates up to 370 x 470 mm.
About the OLED Association (OLED-A)
OLED-A provides a forum for the interchange of technical and market information. Its membership includes companies involved in small-molecule OLED technology and polymer technology (PLED or light-emitting polymers), as well as supporting technologies, as well as companies incorporating OLED displays and light sources into their products. OLED-A serves its membership by fostering the more rapid development of OLED technology and OLED products; serving as a resource on OLED markets and products for media and investors; functioning as a catalyst in the development of standards for OLEDs; and providing a forum to promote and market OLED technology products.
