Organic Light Emitting Diode (OLED) technology has the stars in the fairs of electronics have been this year. At this year's Consumer Electronics Show in Las Vegas, the biggest product introduction was the Sony, with an OLED display. The new 11 "Sony TV called XEL-1." HDTV Sony is extremely thin (less than 1 / 10 ") and lightweight., At FPD International exhibition in Asia in November, a Samsung 31" OLED HDTV-1080p resolution and 1000 war .000: 1 ContrastReport.
Companies such as LG, Toshiba, Matsushita (Panasonic), to invest hundreds of millions of dollars for the development of this promising technology. Toshiba plans to sell a 30 "OLED display in 2009. Samsung said it sells large OLED screen in 2010.
Eastman Kodak has numerous patents in OLED technology. Manufacturers should be required to pay a license fee for each sale Kodak OLED TVs. Eastman Kodak just introduced the OLED Material EK-GD403, usedGreen Technology dopant. Advanced technology is a mass panic.
There are a lot of money to be made. According to DisplaySearch, in 2007, the market for LCD TVs was estimated at 27.4 billion U.S. dollars, while the market for plasma TVs was estimated at 7.5 billion U.S. dollars. An OLED TV could be that the cost of credit in competition for a significant share of the market. DisplaySearch estimates that the OLED market is growing annually by more than 17 billion U.S. dollars by 2015. According to iSuppli, the current market for OLEDEquipment is a little 'more than half a billion dollars a year. Samsung currently has a market share of 70%. But the problems of cost and technology leader in the OLED can be avoided, are used in devices such as televisions high definition or big screens.
Simple wall mounted HDTV
Most consumers say they want an HDTV wall. But according to the NPD Group, consumer and retail research firm Information Market (NPD.com), only 13 percent of current LCD TV owners and 25Say percent of the owners of plasma televisions that their device is mounted on the wall.
"Consumers are flat-panel technology for its ability to wall mount design, but the difficulty of such a system often leads to explore alternatives, such as trees or structures in between. Said Ross Rubin, director of industry analysis, The NPD Group. But the problem with OLED assembly of parts would be much easier to hang like a picture hanging on the wall. The hardware weighs only a fraction of the LCD –or plasma.
OLED Performance
OLED displays are used for some time in digital cameras, mobile phones and other devices with relatively small panels, because they are very efficient, which is very important in portable devices.
One key advantage of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. For this reason, they draw much less power. And why is not illuminated OLED displayis much thinner than an LCD display.
And why is not illuminated, a system of OLED has an angle of more than one system of LEDs and an OLED display is much thinner than an LCD display.
The response time for OLED is faster than normal LCD screens. An average of 8 to 12 millisecond response time is normal for an LCD, compared to the reaction time of 0.01 milliseconds for OLED. This means that OLEDs are less vulnerable, "blur". Blur occurs when a rapid movementProgramming, such as sport. If the situation is changing rapidly, the pixels can be set in the reaction.
One problem is the use of OLEDs is limited, is that the blue OLED technology is a short-lived, but a new type of blue LED, the "PHOLED," has a duration of 20,000 hours TV (20-25 years normal application ). This was an important step in the attempt to integrate this technology for the HDTV market, the integrated market.
Made In theory, OLED displays can be more efficient than LCD or plasmashows, which means that they should not be so expensive. The Sony XEL-1 sells for $ 2500, but you must remember that the first large LCD and plasma displays are much more expensive if it had been introduced. If the production can be reduced, be more convenient for OLED HDTV equipment in the final analysis, comparable LCD models.
OLED Performance Plus:
Power efficienct
Very thin and light, 1 / 4 inch or less
Better than LCD brightness
Wide Viewing Angle (~Viewing angle of 160 degrees)
Excellent contrast (> 1,000,000:1)
Following the development of production is worth the price (the procedure is similar to ink-jet)
Large displays are possible (> 100 cm)
The answer is better LCD (good for fast-moving images such as sports)
If the OLED does not live up to its promise, is not the first display HDTV. I remember the surface-conduction electron-emitter display (SED) TV? Toshiba and CanonPatent disputes are willing to go into production, but by the technology company Nano-Proprietary killed. Probably will not happen this time. The biggest obstacle is the process of production. If the products are produced, can lead to cost competitive with LCD and plasma should be very interesting.
