Difficult to break through the bottleneck size, OLED development of slow progress

 While mobile phones and digital media players and other small electronic equipment market have become the symbol of a high-end technology, but in the field of large-size display, OLED is still developing slowly or lag behind. At the end of March 2010, Sony announced to stop the supply of OLED TVs in the Japanese market because of poor sales of such products in the market. Sony OLED TV is a pioneer in launching the company, it immediately turned around at this time caused by the industry wide concern.

 In fact, large-size market, Sony is only 11 inches, and LG15-inch OLED TV volume sales, not only yield very small, and the manufacturer that this product benefits the company damaged. Although sales of Samsung OLED panel impressive, it is also confined to the small size mobile products market. So why OLED these years has been limited to small screen applications can not be bigger then?

 In the development of OLED technology, the major manufacturers to be outdone, have put into the development and manufacture of OLED panels. Japanese electronics giant Matsushita Electric 3, Canon and Hitachi also announced the formation of strategic alliances, joint development of OLED panels business. Up to now, Samsung, several large-size OLED TVs frequent appearances at the show, LG already has a flexible display technology, Panasonic is also keen on the size of the OLED TV-level research. Even so, OLED TV to market volume still has not seen movement.

 According to UBIndustryResearch investigation, Samsung OLED sales in 2009 accounts for 73% global market share. Samsung’s the SMD company has the world’s largest OLED panel production line. Starting from the first half of this year, Samsung will invest 1.3 billion to build five large-scale generation of line for the production of large-size TV panels, and gradually use its OLED market transition from phone to TV applications.

 But Samsung executives last year in March, said at a public occasion, because of technical and production costs facing many problems, so OLED at least 4-5 years before the mainstream TV market.

 Scale is not even 1% of SMD to the LG Group, Samsung, under strong pressure, had to re-integration of its LG Electronics, LGDisplay and three subsidiary of LG Chemical, OLED joint venture division. First, the acquisition of LG seventies of last century pioneered the development of this technology Kodak’s ultra-thin OLED display technology research and development business. Then in March this year, starting in the procurement of production equipment, ready to build 5th generation line, into TV applications.

 Now it seems that Samsung and LG in the Large size OLED to increase product development and layout Maozuliaojin, they were scheduled in May 2010 and 2011 launch of OLED notebook computer and television.

 Objective look at new technology, OLED are distinct advantages and disadvantages

 The main basis for driving OLED display technology is different categories, divided into passive drive OLED (PM-OLED) and active matrix driving OLED (AM-OLED) are two. Compared with the PM-OLED, AM-OLED has more advantages: AM-OLED prepared using a TFT (thin film transistor) backplane as a graphic display board, so get a bigger display capacity, better display quality, a longer life, thereby making OLED TV display.

 Compared with the current market mainstream LCD, OLED has many advantages: First, OLED can be self-luminous, and only need to light up the unit will power, but you need the lamp for LCD backlighting, so OLED LCD brightness higher than , higher contrast, richer color effects, and because a large number of tubes does not require a backlight, OLED voltage is lower, therefore, more energy-efficient; Secondly, OLED structure of the composition of the solid-state, no liquid material, so a better seismic performance, not afraid wrestling; response time is one-thousandth of LCD TVs, motion picture shows absolutely no smear phenomenon; and it is almost no viewing angle problems, even under large perspective view, the picture still is not distorted.

 However, the shortcomings of OLED enough to kill large size OLED panel production very low yield (less than 30%) leads to high manufacturing costs, LCD panels are able to reach 99%.

 In addition, the short life of OLED technology is also facing problems. DisplaySearch has pointed out, OLED TV’s life only for about 20,000 hours, compared with LCD and LED life expectancy was much shorter, and to achieve the industrial requirements, at least 50,000 hours, these technical barriers to a certain extent, prevented OLED TV, the pace of industrialization. Toshiba said it launched 30-inch OLED 2009, the program proceeds to damage the company in December last year, making the company was to reposition the business, future plans to target mobile phone and other small screen.

 Seen in this light, OLED have reached a bottleneck of the development. This is from 2010 after the companies have to invest in 3D in the LED can be seen. OLED the future will break through the bottleneck to the flat-panel TV industry a new direction, we will wait and see.
