Organic Electroluminescent Device
First Claim
1. An organic electroluminescent device comprising:
- a substrate;
a first electrode disposed over the substrate for injecting charge of a first polarity;
a second electrode disposed over the first electrode for injecting charge of a second polarity opposite to said first polarity;
an organic light emitting layer disposed between the first and the second electrodes, the second electrode being adapted to allow light emitted by the light emitting layer to be transmitted through it; and
a transparent encapsulant disposed over the second electrode, wherein the transparent encapsulant comprises a microlens array formed by a top surface of the transparent encapsulant and a diffraction grating formed by a bottom surface of the transparent encapsulant.

Abstract
An organic electroluminescent device comprising: a substrate; a first electrode disposed over the substrate for injecting charge of a first polarity; a second electrode disposed over the first electrode for injecting charge of a second polarity opposite to said first polarity; an organic light emitting layer disposed between the first and the second electrode, the second electrode being transparent to light emitted by the light emitting layer; and a transparent encapsulant disposed over the second electrode, wherein the transparent encapsulant comprises a microlens array formed by a top surface of the transparent encapsulant and a diffraction grating formed by a bottom surface of the transparent encapsulant.
