OLED TV was not exactly taking center stage at the OLEDs World Summit 2009 in San Francisco.

The 11th annual event started yesterday and winds up today.

Most of the focus is on smaller OLED displays and OLED lighting however. FOr a look at the agenda, click here.

Cnet‘s Erica Ogg was there and provided the following:

“Though LG’s eye-popping OLED (organic light-emitting diode) display wowed audiences in Berlin last month, it’s best not to get too excited. There’s not going to be more where that came from, at least for a while.

The industry is still at least three years away from churning out standard-size televisions of 32 inches or larger at something approaching acceptable prices. And though Sony grabbed all the attention in early 2008 with its $2,500 11-inch OLED, it’s faded into the background when it comes to nudging the technology forward. Initially promising to follow up with 21-inch and 27-inch models, Sony’s deferred those plans while battling bigger problems with its TV business.

With Sony on the sidelines, it seemed like we were witnessing yet another false start for a technology that’s been intent on challenging existing TV standards like LCD and plasma for almost half a decade now.

Beset by the standard issues that come with bringing a new technology into the mainstream, like the exorbitantly high cost of development, OLED TVs might be on the verge of shifting out of neutral as new standard bearers for the technology emerge. The ones to watch now are Samsung and LG Electronics, which have each signaled that they’re ready to make larger investments in OLED technology for TVs.”

Dupont has developed new OLED materials that promise to drastically extend the life of future OLED TVs.

Great advances have been made especially in blue emitting materials;

“In addition, DuPont Displays developed some blue light-emitting materials. Among them, one with color coordinates of (0.14, 0.12) has a current efficiency of 6.0cd/A and a luminance half-life of 38,000 hours when measured with the initial luminance of 1,000cd/m2, according to the company.”

For deeper blues, “If the initial luminance is set at 200cd/m2, which is required for a display, the luminance half-life is calculated to be approximately 41,000 hours,” DuPont Displays said.”

This is far ahead of the current OLED TV material longevity specifically the short blue half-life of the Sony XEL-1 OLED TV.

Good news from Korea. LG Display has launched an OLED TV and OLED Display production line:

“LG Display formally launched an organic light emitting diode (OLED) division at its Gumi plant in North Gyeongsang Province on Thursday.

OLED is touted as a driving force in the next-generation display field, and companies like Sony and Samsung Electronics have already entered the business. Because it does not require additional backlight, OLED panels can be made thinner than 1 millimeter.

LG Display will first focus on developing and producing small products but expand business to producing medium-sized to large televisions, the company said.

LG Display developed an active-matrix OLED (AMOLED) for a 20.1-inch television in 2004, and was the first in the world to produce a 4-inch flexible OLED in May 2007.”
