OLED technology has the opportunity to enter the lighting market

Recently, the Sony Corp will OLED technology into commercial television market, OLED also began to focus on the lighting market, the current OLED technology is mainly used in display applications such as TV and portable equipment products and lighting applications, previously received little attention.

Although the OLED application in the lighting in the next 5 years is not expected to heat up. OLED technology has several advantages over conventional lighting. First, it is delicate. The thickness of the OLED panel for lighting applications can be less than 1mm. This feature allows OLED lighting on the ceiling rather than hanging up. In addition, flexibility is one of the advantages. OLED lighting can be used in a limited space.

OLED lighting is more stable than ordinary lighting. Compared with LED or traditional fluorescent lamps, OLED lighting is more like sunlight, so it looks more comfortable. Not long ago, OSRAM Opto Semiconductors said it has developed a transparent white OLED. The luminous efficiency of 1000cd/m2 is more than 20 lumens per watt.

Although OLED lighting applications have several advantages, but still related to technical issues to be addressed, including luminous efficiency, life and production costs.

OLED panel supplier target is more than 80 lumens per watt. In July 2006, Konica Minolta developed a 1000cd/m2 brightness and life expectancy of 10000 small, luminous efficiency of 64 lumens per watt lighting OLED panel. MITSUBISHI heavy industries, a Japanese OLED lighting panel equipment manufacturer, is expected to OLED luminous efficiency will reach the level of fluorescent lamps in 2010.

Compared with the 100 thousand quarter of 2009, the production cost of OLED panels per square meter for lighting applications will reach $10000 ($87) in 2015. Samsung SDI company said, OLED technology business is not far away, because OLED luminous efficiency is currently 2 times the annual growth. Samsung SDI has now developed 50 lumens per watt and a life of 20 thousand hours, the color of more than 80.
