LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18360048 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
The abstract describes a tandem light-emitting device with multiple light-emitting units stacked between two electrodes, each unit consisting of an emission layer and charge generation layers. The device includes at least five light-emitting units and four charge generation layers, with some units emitting blue light and others emitting green light. The device satisfies the formula 3≤D/(2*λ)≤4.

Original Abstract Submitted
A tandem light-emitting device including a first electrode, a second electrode facing the first electrode, m light-emitting units stacked between the first electrode and the second electrode, the m light-emitting units each including an emission layer, and m−1 charge generation layers between two adjacent light-emitting units of the m light-emitting units. M is an integer of 5 or more. The m light-emitting units include first to fifth light-emitting units, in order of proximity to the first electrode. The m−1 charge generation layers include first to fourth charge generation layers, in order of proximity to the first electrode. At least one of the first to fifth light-emitting units emits blue light. At least one of the first to fifth light-emitting units emits green light. The formula 3≤D/(2*λ)≤ 4 is satisfied.
