The next breakthrough in the domestic optoelectronic display industry will be OLED

OLED, or Organic Light-Emitting Diode, is also known as Organic Electro-Electrosion Display (OELD). Unlike traditional LCD displays, OLED display technology eliminates the need for backlights and uses very thin organic coatings and glass substrates that illuminate when current is passed through. Moreover, the OLED display screen can be made lighter and thinner, has a larger viewing angle, and can significantly save power.

According to market research firm iSuppli's research report, global OLED (Organic Light Emitting Diode) TV shipments will increase from 3,000 in 2007 to 2.8 million in 2013, with a compound annual growth rate of 212.3%. In terms of global sales revenue, global OLED TV sales revenue will increase from US$2 million in 2007 to US$1.4 billion in 2013, with a compound annual growth rate of 206.8%.

However, the development of the OLED display industry in China is slightly slow. Compared with the rapidly emerging LED industry in 2009, the OLED industry is still less popular in China. Its complicated production process, high price, and slightly lower lifespan are difficult. Win the favor of the market. However, the industry is optimistic about OLED, and predict that by 2015, OLED will replace LED as the market leader.

At present, China's OLED production R&D enterprises are all over the country, but the enterprises in the industry lack effective integration, and most of them are small and medium-sized enterprises, and their technological research and development capabilities are limited. However, in foreign countries, a large number of display giants such as Sharp and Toshiba have already begun research and development of OLED products.

According to Databeans, the OLED market will increase by 40.8% to US$2.2 billion in 2009, and will grow by 18.6% in CAGR from 2009 to 2014, and US$5.17 billion in 2014.

Recently, Sony's OLED large-size TV will soon be available, and China's first OLED production line is expected to be put into production in Dongguan at the end of the year. We are behind in the LED era, and the OLED era must shorten the gap.

Although the development of the OLED industry has just started, we have foreseen its strong future. Although the current OLED material production technology is poor, the product level is not good, it is difficult to mass production, and the life is slightly shorter, but its development speed is gratifying. Taking OLED life as an example, in 2003, the lifetime of OLED products was only 2,000 hours. In 2005, it reached 10,000 hours. In 2007, Epson exceeded 50,000 hours of OLED life. At the SID Display Week in Texas in 2009, DuPont demonstrated their newly developed third-generation OLED organic light-emitting materials. Among them, a green luminescent material has an initial brightness of 1000 cd/m2 and a lifetime (half of brightness). ) More than 1 million hours, equivalent to 100 years of continuous illumination.

Xiaobian reviews:

In recent years, China's display industry has lagged behind foreign countries. Today, LED display has begun to flourish. We should be able to see that OLED is bound to become the next generation of mainstream products. How to break the development model of “one step, one step” for domestic enterprises Taking the lead in breaking through the technical difficulties and promoting products will be a difficult problem for the domestic display industry. Only with the leading technology, we will not be subject to people in the future development, and the future of the domestic OLED display industry will be brilliant.
