Method of forming an electronic device

摘要

A method of forming a patterned diode or light emitting diode (led) on a flexible or rigid substrate using the technique of drop on demand printing to deposit a plurality of droplets of polymeric electroluminescent material that when suitably dried or solidified form the layers of the device. A lens array may also be deposited. The electroluminescent material may be tuned for a specific wavelength range, and suitable materials include poly(p-phenylene) (PPV) and MEH-PPV.
