LIGHT EMITTING ELEMENT AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17967177 titled 'LIGHT EMITTING ELEMENT AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a light emitting element with a core consisting of a first area and a second area surrounding it. The core includes multiple semiconductor layers doped with different dopants, and an active layer between them. The second area is located on the outer circumference of the core and includes the outer surface. The doping concentration of the second dopant in the third semiconductor layer is lower than the defect density of the second area.
- The light emitting element has a core with distinct areas and multiple semiconductor layers.
- The second area of the core is located on the outer circumference and includes the outer surface.
- The core includes an active layer between the first and second semiconductor layers.

Original Abstract Submitted
A light emitting element includes a light emitting element core including a first area and a second area surrounding the first area. The light emitting element core includes a first semiconductor layer doped with a first dopant, a second semiconductor layer disposed on the first semiconductor layer and doped with a second dopant, an element active layer disposed between the first semiconductor layer and the second semiconductor layer; and a third semiconductor layer disposed between the element active layer and the second semiconductor layer and doped with the second dopant. The second area of the light emitting element core is located on an outer circumference of the light emitting element core and includes an outer surface of the light emitting element core. A doping concentration of the second dopant of the third semiconductor layer is lower than a defect density of the second area of the light emitting element core.
