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

This abstract first appeared for US patent application 18218563 titled 'LIGHT-EMITTING DEVICE AND APPARATUS INCLUDING SAME

Simplified Explanation

The patent application describes a light-emitting device and an apparatus that includes this device.

• The device consists of a first electrode, a second electrode, and an organic layer between them.
• The organic layer contains m emission units and (m-1) charge generating units.
• Each charge generating unit is positioned between two adjacent emission units.
• The value of m is a natural number of 2 or greater.
• At least one of the (m-1) charge generating units includes an n-type charge generating layer, a p-type charge generating layer, and a p-type hole injection layer.
• The n-type charge generating layer consists of an n-type organic compound and a metal material.
• The p-type charge generating layer and the p-type hole injection layer each contain an inorganic semiconductor material.

Original Abstract Submitted

A light-emitting device and an apparatus including the same include a first electrode, a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, wherein the organic layer includes m emission units and (m−1) charge generating units, each of the charge generating units being between the emission units that are adjacent to each other, m is a natural number of 2 or greater, at least one of the (m−1) charge generating units includes an n-type charge generating layer, a p-type charge generating layer, and a p-type hole injection layer, wherein the n-type charge generating layer includes an n-type organic compound and a metal material, and wherein the p-type charge generating layer and the p-type hole injection layer each independently include an inorganic semiconductor material.
