OLED will replace LCD? OLED to a variety of factors will determine – Mosaic texture manufacturer
Display technology development to the present, CRT technology has largely been replaced by LCD, but LED technology in front of more advantage, LCD can go further it?
Organic light-emitting diode displays (Organic Light Emitting Diode; OLED) for the use of light emitting components of organic compounds, as a self-luminous properties, their thin, animation, performance and power saving features than LCD, according to driving methods can be divided into passive ( PM) and active (AM), which, AMOLED favor large, and some manufacturers have already launched large size AMOLED display, much market attention. The small size AMOLED gradually be expanded with high-end mobile phones.

Display technology development to the present, CRT technology has largely been replaced by LCD, but LED technology in front of more advantage, LCD can go further it?
Organic light-emitting diode displays (Organic Light Emitting Diode; OLED) for the use of light emitting components of organic compounds, as a self-luminous properties, their thin, animation, performance and power saving features than LCD, according to driving methods can be divided into passive ( PM) and active (AM), which, AMOLED favor large, and some manufacturers have already launched large size AMOLED display, much market attention. The small size AMOLED gradually be expanded with high-end mobile phones.
OLED, the structure more simple PMOLED developed earlier, in 2005 the supply of sub-screen mobile phone and portable music players such as significant increase in shipments to drive OLED market growth. The AMOLED due to circuit complexity than PMOLED, manufacturing costs are high, not yet formally universal, but for mobile phones and other small-size panels used in the market, because prices down closer to the same size LCD, is expected to accelerate growth. It is understood that the current price of 2.4-inch AMOLED panel is about 26 ~ 30 dollars, with 2.4-inch low temperature polysilicon (LTPS) TFT-LCD panel means about 15 dollars compared to about 2 times the price has been very competitive with the market. On the other hand, despite the 2.4-inch AMOLED panel with a lower 2.4-inch amorphous silicon (a-Si) TFT-LCD (about 10 ~ 15 dollars), compared to 3 times the price up to about 2.5, and 2 and the most popular inch STN LCD (about 5 ~ 9 USD) compared to up to four times more than the price, but start with high-end mobile phone market to replace part of the LCD, the opportunity is still quite distinct, suggesting that the mainstream size OLED 2008, PMOLED to 1 inch or so to Lord, AMOLED 2 to 3 inches mainly.

Despite the small size AMOLED display certain areas of performance, but because of large-size product development difficult, high cost PC monitor and TV market in the short term to improve competitiveness will not be much. The other, according to South Korean media reports, Sony 2008 TV with 11-inch AMOLED panel compared with a 2007 average price decreased by about 17% to about 620 ~ 629 U.S. dollars, but still with more than 5 times the size of LCD. Even if the opening of Sony TV with AMOLED production line mass production, the price is expected to decline, but forecast 1 to 2 years later with AMOLED TV will remain about 3 times more LCD prices could not be in direct competition with LCD TV.
Observed in recent large TV markets, LCD TV and PDP TV competition, PDP TV animation performed better though, but in normal circumstances such as losing power consumption LCD TV, the two camps to improve the shortcomings of R & D has been hard. In contrast AMOLED existing technology standards, in thin, animated performance, although power consumption than LCD, but life, and the large scale mass production of LCD but it can not compete, in particular the cost of one of the key face more disadvantages Department, the future AMOLED officially entered the war situation in the TV market is so fierce, too to compete with LCD PDP, the difficulty is quite high.
To make use of AMOLED TV price cuts will definitely need more large scale of mass production technology, however, AMOLED existing technology is only suitable for the development of mass production to 4 on behalf of the line, as after the 4th generation line of what technology should be adopted, yet no one global Manufacturers say categorically.
Currently AMOLED market, South Korea's Samsung SDI tops nearly seven percent market share, Taiwan's CMEL market share of nearly 2 percent, LG Display market share of about 7%, almost dominated by South Korea and Taiwan, but still small size AMOLED the mainstream. AMOLED market to recoup their losses in the city, the Japanese look large AMOLED, from Sony, Sharp (Sharp) and Toshiba Matsushita Display Technology (TMD) and other major Japanese companies such as display, composed of large-size OLED displays Japan's alliance plans to develop the next generation of large OLED display-related technologies, such as over a large 40-inch panel technology, power-saving technology and enhance the durability of technology. The Alliance In addition to a research institute, Institute of Advanced Industrial Technology Research Institute, General (AIST), there are 10 enterprises, of which, including the OLED panel plant, materials and equipment industry and other businesses.
Recalling the history of LCD, OLED price cuts to follow competition popular model, is still in its infancy. On the whole, there is still the current 4th generation AMOLED production line technology is not yet established after the crisis, but with South Korea and Japan, display-related companies rush to invest, but also have the opportunity to appear, such as LCD driving technology advances due to fierce competition and price collapse the market and then take off the turn.
