METHOD FOR FABRICATING ORGANIC LIGHT-EMITTING DIODE AND ORGANIC LIGHT-EMITTING DISPLAY USING SCREEN -PRINTING

摘要

A method for fabricating organic light-emitting diodes (OLEDS) and OLED displays using screen-printing, where a first electrode, at least one organic material, and a second electrode are formed on a substrate and at least one of the first and second electrodes and the at least one organic material is screen printed by positioning a screen with openings forming a pattern above a substrate and depositing a material onto the substrate through the openings. Exemplary embodiments include fabricating the electrodes and/or the at least one organic material as continuous layers or uniform, discrete blocks on the substrate and fabricating red, green, and blue OLEDs on the same substrate, which are then placed in OLED displays.
