3. Visualization applications
By incorporating the best high-purity organic electroluminescent materials into optimized diode structures, it has been possible in recent years to improve diode performance to such an extent that the production of small displays and the demonstration of more complex display devices have become a reality. In what follows, before presenting the industrial state of the art, we will first discuss the specific problems associated with addressing and coloring organic electroluminescent materials.
3.1 Addressing
An image is created by juxtaposing elementary points called pixels. The greater the number of pixels, the better the image resolution. The problem with addressing is that each pixel must be brought up to the level of brilliance required to create the desired...

Production
The OLED industry is now a reality. There are some twenty production sites worldwide belonging to
Pioneer, RiTDisplay, Samsung SDI, TDK, Sanyo/Kodak(AM), Teco, Univision, Ness for evaporated molecules and Delta Optronics, DuPont/RiT display, Osram for polymers.
Estimated at :
20 million passive matrix displays sold in 2003;...

A distinction must be made between evaporated molecules and polymers.
Evaporated molecules
A number of evaporated molecules are included in classic fine chemicals catalogs (Aldrich, Lancaster, etc.).
Other molecules are sold specifically by certain companies, such as :
