CASCADED LIGHT EMITTING DEVICES BASED ON MIXED CONDUCTOR ELECTROLUMINESCENCE
First Claim
1. A cascaded light emitting device, comprising:
- a split electrode structure formed of a first electrode material, the split electrode structure includes a plurality of electrode portions, an electrical resistance between any pair of electrode portions of the split electrode structure being greater than a split resistance, the plurality of electrode portions including a first electrode portion electrically coupled to a first voltage lead and a second electrode portion electrically coupled to a second voltage lead;
an opposing electrode formed of a second electrode material; and
at least one electroluminescent layer coupled between the split electrode structure and the opposing electrode, the at least one electroluminescent layer including a mixed conductor that luminesces with a peak wavelength, a total thickness of the at least one electroluminescent layer being such that a resistance across the at least one electroluminescent layer between an electrode portion of the split electrode structure and the opposing electrode is less than half of the split resistance.

Abstract
A cascaded light emitting device. The cascaded light emitting device includes: a base electrode formed of a base electrode material and electrically coupled to a base voltage lead; a top electrode layer formed of a top electrode material and electrically coupled to a top voltage lead; a number of electroluminescent layers arranged between and electrically coupled to the base electrode and top electrode layer; and at least one middle electrode layer formed of a middle electrode material. Each of the middle electrodes is coupled between two juxtaposed electroluminescent layers. The electroluminescent layers include a mixed conductor that luminesces with a peak wavelength.
