Organic Light Emitting Diode (OLED) technology has stars in entertainment electronics trade have been this year. This year at the Consumer Electronics Show in Las Vegas, the biggest product introduction was the Sony with an OLED screen. The new 11 "Sony TV is called the" XEL-1. "HDTV Sony is very thin (less than 1 / 10") and lightweight. At the FPD International exhibition in Asia in November was a Samsung 31 "OLED HDTV with 1080p resolution, 1,000,000:1Contrast ratio.
Companies such as LG, Toshiba, Matsushita (Panasonic), hundreds of millions of dollars to invest, the development of this promising technology. Toshiba plans to sell 30 "OLED in 2009. Samsung said it sold large OLED display in 2010.
Eastman Kodak has a subject of several patents in OLED technology. Manufacturers should be required to pay a license for each sale Kodak OLED TVs. Eastman Kodak just introduced the OLED Material EK-GD403,The technology uses green dopant. Technological advance 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 dollars, while the market for plasma TVs was estimated at 7.5 billion dollars. An OLED TV that costs would likely compete for a significant share of the market maintain. DisplaySearch estimates that the OLED market is growing annually at over 17 billion dollars by 2015. According to iSuppli, the currentOLED devices market is a little over half a billion dollars a year. Samsung currently has a market share of 70%. But to have avoided the problems of cost and technology leader in OLEDs are used in larger devices such as HD televisions or computer monitors.
Easy wall mount HDTV
Most consumers say they want a wall mounted HDTV. But, according to NPD Group, consumer and retail market research firm Information (NPD.com), only 13 percent of the current LCDOwners of television and 25 percent of plasma TV owners say their device is mounted on the wall.
"Consumers are flat panel technologies in building wall mount designed, but the difficulty of such a system often leads to explore alternatives such as capacity or through the facilities. said Ross Rubin, director of industry analysis, The NPD Group. But the problem with the Assembly OLED material would be much easier, like a painting on the wall. The equipment weighsPart of the LCD or plasma.
OLED Performance
OLED screens are used for some time in digital cameras, mobile phones and other devices with relatively small panels, because they are very energy efficient, which is very important in portable devices.
A 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 because it's no backlight,OLED screens are much thinner than an LCD.
And because it's no backlight, an OLED system has an angle greater than a system of LED and OLED display is much thinner than an LCD.
The response time for OLED is faster than normal LCD screens. An average of 8 to 12 milliseconds response time is normal for an LCD, compared to 0.01 milliseconds for a response time of OLED. This means that OLEDs will be less vulnerable to the "fuzzy". Blur occurs whenrapid movement in programming such as sports. If the situation changes quickly, the pixels can lay in the reaction.
One problem, the OLED has a limited use, is that the blue OLED has a short lifespan, but a new type of blue LED, the "PHOLED", has a lifespan of 20,000 hours (20-25 years under normal TV). This was a major breakthrough in efforts to incorporate this technology to the market for HDTV on the market.
In theory, OLED displays can be produced more efficientlythan LCD or plasma, so they should not be so expensive. The XEL-1 Sony sells for $ 2,500, but you should remember that the large LCD screen were first plasma screens and much more expensive when they were first introduced. If production costs can be reduced if the OLED HDTV set will ultimately be cheaper than comparable models for liquid crystals.
OLED Performance Plus:
Power efficienct
Very slim and lightweight, 1 / 4 inch or less
Better than the LCD brightness
WideViewing angle (~ 160 ° viewing angle)
Excellent contrast (> 1,000,000:1)
After developing the manufacturing process is to value price (the procedure is similar to the jet printing ink)
Very large displays are possible (> 100 cm)
The answer is better than LCD (good for fast moving images such as sports)
If the OLED does not live to its promises, it will not display HDTV first. Remember the surface-conduction electron-emitter display (SED television)?Toshiba and Canon have been willing to go into production, but was killed a patent dispute with Nano-Proprietary business technology. This probably will not happen this time. The biggest obstacle is the production process. If the products are manufactured, can cost up to competition with LCD and plasma, it should be very interesting.
