OLED lighting commercial production at least 1 to 2 years

Because the key obstacles of OLED lighting in the short term as well as service life, luminous efficiency and cost, the industry believes that the OLED lighting products to import production and commercialization stage, but also may be at least 1-2 years later than LED lighting.

OLED refers to the phenomenon of light emission by carrier injection and recombination under the electric field. The principle is to use a transparent ITO glass electrode and the metal electrode as anode and cathode devices, driven in a certain voltage, the electrons and holes are injected from the cathode and anode to electron and hole transport layer, and then migrate to the emitting layer, the luminescent molecules meet exciton excitation, the latter after irradiation of visible light. The radiation can be observed from the side of the ITO, and the metal electrode film also acts as a reflector.

According to market research firm DisplaySearch predicts that OLED in the display (Display) and lighting (Lighting) two applications market development, bright prospects. Although only a few vendors in the supply of OLED related products, but it is estimated that in 2010 the global OLED industry output value has stood on the $1 billion mark. As more and more manufacturers gradually into mass production, will increase the supply of OLED, OLED market size will continue to expand rapidly. 2011 output value of more than 2 billion U.S. dollars, the annual growth rate of 100%.

At present, the two major OLED application market for display and lighting, which is more rapid development of display applications. At this stage there are many mobile phones, MP3, digital cameras, automotive displays and other consumer electronics products, import PMOLED panel or AMOLED panel. As for OLED lighting applications, according to the opinions of the scholars, OLED lighting is energy-saving and carbon reduction, no mercury, no UV, no infrared, no fever, no glare, light, low driving voltage, design of intelligent dimming and soft flexible characteristics and advantages, in recent years has won many international brands in the development of lighting.

But because the key obstacles of OLED lighting in the short term as well as service life, luminous efficiency and cost, the industry believes that the OLED lighting products to import production and commercialization stage, but also may be at least 1-2 years later than LED lighting.
