Abstract:
A method of treating an organic light emitting device, comprising:providing an as-fabricated organic light emitting device, comprising: an anode; a cathode; and a light emission region that emits light between the anode and cathode, the light emission region including an organic light emitting material; and annealing the as-fabricated organic light emitting device at an annealing temperature from about 50Â° C. and below 100Â° C. and for an annealing period effective to (i) decrease an operating voltage of the as-fabricated organic light emitting device, and (ii) increase an energy conversion efficiency of the as-fabricated organic light emitting device; wherein the annealing temperature is below a glass transition temperature of a material of the organic light emitting device.
