Although OLED lighting products are still only in the early stages, the brightness, efficiency and longevity of O LED lighting devices have reached a very high level at the research and development level, such as Kodak, UDC, Philips. (Philips), Siemens (Simens), research Osram (Osram) and Novaled companies have achieved good results. In the process of OLED lighting industrialization planning, in addition to continuing to improve the efficiency and longevity of white OLEDs, these enterprises have already lowered the price as the main research and development direction, and even incorporated upstream material suppliers and equipment manufacturers into the plan, in order to form a complete The industrial chain promotes the development and market application of OLED lighting products.
It is understood that Philips, GE, Konica Minolta, Lumiotec, OSRAM and other international companies are expected to launch OLED lighting products in 2010-2012. In fact, these large companies have begun small-scale production of OLED lighting products (the world's major companies plan OLED The mass production roadmap for lighting products is shown in Figure 1). Despite this, OLED lighting has reached the level of fluorescent lamps and is widely used. There are still many problems to be solved, including efficiency, life and production costs, and cost should be a key factor restricting the popularity of OLED lighting.

OLED lighting should reach the application level of fluorescent lamps in efficiency, and its power efficiency should be at least 70lm/W. Although OLED lighting devices of about 100lm/W have been reported so far, this is manufactured under very extreme conditions, usually The efficiency of the OLED lighting device manufactured in the case is only 30~50lm/W, which is obviously far from the requirement.
