Color-tunable OLED lighting device
First Claim
1. A color-tunable OLED device comprising:
- a. a charge-carrying cathode layer and a charge-carrying anode layer disposed parallel to each other;
b. at least a first organic light-emitting unit and a second organic light-emitting unit disposed between the charge-carrying cathode layer and the charge-carrying anode layer; and
c. at least one charge-generating layer disposed between the charge-carrying cathode layer and the charge-carrying anode layer, wherein the charge-generating layer is a charge-carrying layer of lesser lateral conductivity than the charge-carrying anode layer and the charge-carrying cathode layer, and said charge-generating layer is electrically connected without additional circuit elements to another charge-carrying layer and disposed such that at least the first organic light-emitting unit or the second organic light-emitting unit is wedged between the electrically connected charge-generating layer and the another charge-carrying layer, and at least the first organic light-emitting unit or the second organic light-emitting unit is not wedged between the electrically connected charge-generating layer and the another charge-carrying layer,wherein the another charge-carrying layer is the charge-carrying cathode layer or the charge-carrying anode layer.

Abstract
A color-tunable OLED device comprising: a charge-carrying cathode layer and a charge-carrying anode layer disposed parallel to each other; at least a first organic light-emitting unit and a second organic light-emitting unit disposed between the cathode and anode; and at least one charge-generating layer disposed between the cathode and anode, wherein the charge-generating layer is a charge-carrying layer of lesser lateral conductivity than the anode and cathode, and said charge-generating layer is electrically connected without additional circuit elements to another charge-carrying layer and disposed such that at least one organic light-emitting unit is wedged between two directly-connected charge-carrying layers, and at least one organic light-emitting unit is not thusly wedged.
