ORGANIC LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324070 titled 'ORGANIC LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME

Simplified Explanation

The patent application describes an organic light emitting device that includes electrodes, an interlayer with an emission layer, and a capping layer.

  • The emission layer contains a red light emitter called iridium, which has a specific photoluminescence spectrum.
  • The spectrum has a peak with the highest intensity and another peak with the second highest intensity.
  • The ratio of the intensity of the second peak to the intensity of the first peak is less than or equal to 0.5.
  • The capping layer of the device includes a compound that is free of amines.


Original Abstract Submitted

Provided is an organic light emitting device including a first electrode, a second electrode facing the first electrode, an interlayer between the first electrode and the second electrode and including an emission layer, and a capping layer outside the first electrode or the second electrode. The emission layer includes a first emitter, the first emitter emits red light and includes iridium, a photoluminescence (PL) spectrum of the first emitter includes a first peak (I) having a maximum intensity and a second peak (I) having a second highest intensity, and a ratio (I/I) of an intensity of the second peak to an intensity of the first peak is less than or equal to 0.5. The capping layer includes an amine-fee compound.
