5. OLED applications

The desire to develop OLEDs for the lighting market is very strong, and is evident in the large number of international projects underway. Most of the world's leading lighting and display companies (such as Osram, Philips, Siemens, General Electric, Samsung...) are investing and actively participating in these projects. Among these is the European OLLA project, which brought together 24 partners from 8 countries with the aim of developing high-efficiency, high-luminance white OLEDs over a four-year period (2004-2008), in order to demonstrate their use in the lighting sector. This project ended with the design of a white OLED achieving an efficiency of 50 lm/W at a luminance of 1,000 cd/m ² , and encouraged various partners to renew the project under the name OLED100.EU with new objectives (100 lm/W for a lifetime of 100,000 h).
