5. Conclusion
The enormous progress made since the discovery of electroluminescence in organic materials has enabled the creation of an industry for small passive displays. To go beyond this, it is essential to improve lifetimes and reduce production costs, which is difficult because development and production take place at the same time.
A few big questions remain:
what is the best approach for producing the active matrix (amorphous silicon, polycrystalline silicon)?
should both polymer and evaporated molecule routes be maintained?
what is the best industrial technique for depositing materials?

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;...

(non-exhaustive list)
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 :
