Claims18
A method for fabricating an electroluminescent display device comprising:
- encapsulating particles of a light emitting polymer with a conductive polymer to form encapsulated light emitting polymer particles having a conformal coating of a conductive polymer;
- formulating a printing ink by mixing the encapsulated light emitting polymer particles with a binder polymer;
- depositing a rear electrode onto a substrate in a pattern;
- depositing the printing ink onto the rear electrode to form an illumination layer;
- depositing a transparent hole transporting electrode onto the illumination layer;
- depositing a front outlining electrode onto the hole transporting electrode;
- and
- depositing connection leads to the rear electrode and the front outlining electrode.
