LIGHT-EMITTING ELEMENT, METHOD OF FABRICATING THE LIGHT-EMITTING ELEMENT, AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18606347 titled 'LIGHT-EMITTING ELEMENT, METHOD OF FABRICATING THE LIGHT-EMITTING ELEMENT, AND DISPLAY DEVICE

The abstract describes a patent application for a light-emitting element that includes various semiconductor layers and a shell layer with a divalent metal element.

• The light-emitting element has a first semiconductor layer with a first polarity, a second semiconductor layer with a second polarity different from the first, and a light-emitting layer between them.
• A shell layer is formed on the side surfaces of the semiconductor layers and the light-emitting layer, containing a divalent metal element.
• An insulating film covers the outer surface of the shell layer and surrounds the side surface of the light-emitting layer.

Potential Applications: - LED lighting - Display technology - Optoelectronic devices

Problems Solved: - Enhanced light emission efficiency - Improved durability and stability of the light-emitting element

Benefits: - Higher brightness and energy efficiency - Longer lifespan of the light-emitting element - Better performance in various applications

Commercial Applications: - Manufacturing of LED products for various industries - Integration into electronic devices for improved display quality

Questions about the technology: 1. How does the presence of the divalent metal element in the shell layer impact the performance of the light-emitting element? 2. What specific advantages does the insulating film provide in terms of the overall functionality of the element?

Original Abstract Submitted

A light-emitting element includes a first semiconductor layer doped to have a first polarity, a second semiconductor layer doped to have a second polarity different from the first polarity, a light-emitting layer disposed between the first and second semiconductor layers, a shell layer formed on side surfaces of the first semiconductor layer, the light-emitting layer, and the second semiconductor layer, the shell layer including a divalent metal element, and an insulating film covering an outer surface of the shell layer and surrounding the side surface of the light-emitting layer.
