OLED industrialization road obstacles, the urgent need to break through

At present, OLED is the main reason of the weakness in TFT-LCD panel market competition, mainly due to three major problems: one is the OLED's own production cost and service life of the product is two, three is a large screen. OLED to break up in the panel industry, the need to break through more than three major challenges.

For the high cost of production, mainly due to the relatively small number of manufacturers, leading to economies of scale can not play a role, resulting in higher production costs. In fact, the OLED panel materials required for the production process is much simpler than LCD, as long as the market to achieve the scale of production, the cost will naturally fall significantly. At present, Samsung SDI proposed the use of printing and other production technologies, hoping to achieve flexible production to reduce production costs.

For mobile phones and portable applications such as MP3, the current OLED panel 10 thousand hours of life has been basically enough. But for the display, TV and other large panel, a longer life is still a breakthrough in the market to enter the challenge. In this regard, Japan's Seiko Epson (Seiko EPSON) full of confidence, to 2010 40 inches W-XGA OLED panel life can reach at least 30 thousand hours.

OLED flat panel display to seize market share, must cut a large size panel field maximum usage, such as notebook computer, LCD monitor, LCD TV display screen, it can be said that the large panel size is the inevitable trend of the application domain of OLED. However, at present, many manufacturers choose to use the TFT-LCD panel LTPS-TFT as a OLED substrate, the yield is generally only 40% of the low. In addition, there are only first to 3.5 generations of steam plating machine supply, large size OLED manufacturing required for more than 4 generations of machines are not available. Therefore, the good product realization of large screen OLED products of mass production and high rate of OLED and LCD, is a difficult problem for the panel industry must break across meet as equals before.
