DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240107859 titled 'DISPLAY DEVICE

Simplified Explanation

The display device described in the patent application includes multiple layers to protect the light-emitting element and ensure its longevity. Here is a simplified explanation of the patent application:

• The display device consists of a substrate, a light-emitting element with a pixel electrode, an emissive layer, and a common electrode.
• A capping layer is placed on the common electrode, followed by a support layer and a thin-film encapsulation layer.
• The thin-film encapsulation layer comprises a first inorganic encapsulation layer, a first organic encapsulation layer, and a second inorganic encapsulation layer.
• A buffer layer, made of an inorganic material, is positioned between the first organic encapsulation layer and the second inorganic encapsulation layer.
• The buffer layer has a thickness ranging from 0.05 times to 0.3 times the thickness of the second inorganic encapsulation layer.
