| titleOfInvention | Modification of polymer optoelectronic properties after film formation impurity addition or removal |
| abstract | The methods of this invention involve modification of an organic film after it has been deposited by either adding new dopants into it from top or bottom surface, or by causing dopants to leave the film from its top or bottom surface. In the examples of these methods, the emitting color of light emitting diodes are modifed based on doped polymers by locally introducing dopants causing different color emission into the film by local application of a solution containing desired dopant to the film surface (by ink-jet priniting, screen printing, local droplet application, etc.). This covers the difficulties of encountered with direct patterning of three separately formed organic layers (each which uniformely coats an entire surface when formed) into regions for separate R, G, and B devices due to sensitivities of the organic materials to chemicals typically used with conventional patterning technologies. Alternatively, dopants may be introduced in an organic film (16) by diffusion from one layer (18, 19) into the film (16). Alternatively, dopants may be selectively removed form a film with solvents, etc. |
