Abstract
An electroluminescent cell can comprise a first electrode; a second electrode; and an electroluminescent layer disposed between the first electrode and the second electrode. The second electrode can comprise a light-transmitting electrode layer that can comprise electrically conductive regions interspersed by light-transmitting regions. The light-transmitting regions can have higher light-transmissivity than the electrically conductive regions.
Claims15
An electroluminescent cell comprising:
- a first electrode;
- a second electrode;
- and
- an electroluminescent layer disposed between the first electrode and the second electrode;
- wherein the second electrode comprises a light-transmitting electrode layer that comprises electrically conductive regions interspersed by light-transmitting regions, said light-transmitting regions having higher light-transmissivity than the electrically conductive regions.
2 more elements
A method of electrophotographically printing an electroluminescent cell, said method comprising
- disposing an electroluminescent layer over a first electrode, and
- forming a second electrode over the electroluminescent layer by electrophotographically printing an electrophotographic composition as a light-transmitting electrode layer;
- wherein the electrophotographic composition is electrophotographically printed to form electrically conductive regions interspersed by light-transmitting regions, said light-transmitting regions having higher light-transmissivity than the electrically conductive regions.
