SAMSUNG Electronics Develops World’s First 40-inch a-Si-based OLED for Ultra-slim, Ultra-sharp Large TVs
Press Release
Samsung Electronics, the leader in TFT-LCD technology, has successfully
developed the world’s first single-sheet, 40-inch active matrix (AM)
OLED ( organic light-emitting diode ) for emissive flat panel TV
applications. The high-definition-compatible OLED prototype has a wide
screen pixel format of 1280×800 (WXGA) driven by an amorphous silicon
(a-Si) AM backplane to permit faster video response times with low
power consumption.

Samsung’s 40-inch OLED panel was demonstrated for the first time at the
world’s largest display industry event, Society for Information Display
(SID) 2005 International Symposium, Seminar and Exhibition in Boston,
May 24- 27.
Manufactured on Samsung’s fourth generation (4G) production line with a
mother-glass size of 730mm x 920mm, the new OLED prototype combines all
of the traditional features of emissive OLED technology, including wide
viewing angle, thin package size, no color filter and no backlight,
with the enormous production infrastructure advantages of standard a-Si
techniques. To date, AM OLED prototypes have used costly polysilicon
approaches, which have limited production sizes.
Shattering traditional AM OLED size limitations, the new prototype
offers a maximum screen brightness of 600 nits; a black-and-white
contrast ratio of 5,000:1; and, a color gamut of 80 percent. Motion
pictures with ultra-high quality images can be impeccably reproduced by
skillfully employing OLED’s rapid video response capabilities for image
processing of HD-class resolution. The ultra-thin shape of the panels
will allow future TV set designers to create televisions with a total
thickness of only 3cm or less.
After launching its OLED development initiative in 2001 to secure
leadership in next-generation display technologies, Samsung developed a
14.1″ WXGA (1280×768) OLED panel in 2004, followed by the world’s first
21″ HD-class (1920×1080) OLED panel in January, 2005. This ambitious
pace of innovation accelerated development of today’s unusually large
40-inch OLED prototype, paving the way for large-size OLED TVs.
“Our development of a 40-inch OLED will provide a firm basis from which
we can become the unassailable market leader in the flat panel display
market of the future,” said Dr. Kyuha Chung, vice president of Samsung
Electronics LCD R&D Center . “We’re taking an early leadership
position in the next-generation display market, building on Samsung
Electronics’ success in the TFT-LCD market.”
Samsung Electronics is the supervisory and lead research institution
for detailed implementation of the Ministry of Commerce, Industry &
Energy’s (MOCIE) Next-Generation Growth Engine Industries Initiative.
The latest round of development has been conducted as part of the
project, “Development of Solution-Based AM OLED for Low-Cost 4G HDTVs
using a-Si.”
