At the just-concluded IFA Berlin Consumer Electronics Show in Germany, a TV with a 15-inch OLED panel developed by LG Display has received much attention. It has a resolution of 1366 768 and a contrast ratio of 1 million:1. It is reported that this OLED TV is expected to be listed in South Korea in November, and may be listed in the US from February to March next year, the price is about 2,500 US dollars.
OLED will become the next generation display technology
OLED is an abbreviation of Organic Light-Emitting Diode. In order to illustrate the OLED structure, each OLED unit can be compared to a hamburger. The luminescent material is the vegetable sandwiched in the middle, and the display unit of each OLED can be affected. Controlly produces three different colors of light.
OLED display technology is mainly classified into two types according to different driving modes: passive driving OLED (PM-OLED) and active driving OLED (AM-OLED). Compared with PM-OLED, AM-OLED has more advantages: AM-OLED adopts a backplane prepared with TFT (Thin Film Transistor) pattern as a display substrate, so that it can obtain larger display capacity, better display quality, Longer life, which enables OLED TV display. In terms of energy saving, AM-OLED shows an unusual advantage. The power consumption of a 29-inch CRT TV is about 100 watts. The power consumption of a 40-inch TFT-LCD TV is about 200 watts. The power consumption of a 50-inch PDP. Above 500 watts, and a 40-inch AM-OLED TV, the power consumption will be below 100 watts, and because it is self-illuminating, the actual power consumption will be lower.
Compared with mainstream liquid crystals currently on the market, OLEDs have many advantages: First, OLEDs can emit light by themselves, and only cells that need to be lit will be powered, while liquid crystals require lamps as backlights, so OLEDs have higher brightness than liquid crystals. The contrast is larger, the color effect is more abundant, and since a large number of lamps are not required as a backlight, the OLED voltage is lower and more energy-saving; secondly, the composition of the OLED is a solid structure, and there is no liquid substance, so that the seismic performance is better, and it is not afraid The response time is one thousandth of that of the LCD TV. There is absolutely no smear in the motion picture; and it has almost no problem of the viewing angle. Even when viewed under a large angle of view, the picture is still not distorted. It is conceivable that if OLEDs are used as TV panels, it will give us a lot of visual enjoyment.
OLED TV development prospects are promising
Sony launched the 11-inch OLED TV set at $1,800 in the Japanese market in December 2007, first entering the market, but for a variety of reasons there was no longer a larger size follow-up model. Until this year's IFA show, LG launched a 15-inch OLED TV, which has become the largest model for commercialization to date.
Major manufacturers seem to have heard the future of the OLED market. According to Nano Markets, the OLED market will reach $436 million in 2009 and $1.2 billion by 2010. Market research company Display Search also expects that OLED TV sales will reach 2.33 million units in 2010.
The huge market has enabled more and more companies to join the OLED research and development team. Many manufacturers including SONY, Toshiba, Panasonic and LG Display have also said that they are developing or about to develop new OLED TVs. Accelerate the commercial pace of OLED. LG Display CEO, Shou said that LG's large-size OLED TV will be just around the corner. "We plan to produce 32-inch OLED TV panels in 2012," he added. "The success of OLED's commercial operations lies in How does LCD technology show its outstanding superiority?"
