LIGHT-EMITTING DEVICE AND DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240274586 titled 'LIGHT-EMITTING DEVICE AND DISPLAY APPARATUS
The present application describes a light-emitting device with high luminous efficiency and preferable wavelength uniformity. The device includes a substrate, at least two light-emitting units, and at least one patterned bonding layer located between the light-emitting units.
- The light-emitting device includes a substrate and at least two light-emitting units.
- The orthographic projections of two adjacent light-emitting units on the substrate overlap.
- A patterned bonding layer is located between the light-emitting units, with spaced bonding portions that are fixed and electrically connected to the adjacent units.
- The bonding portions on the substrate have orthographic projections within the light-emitting unit projections.
- The sum of the bonding portion areas on the substrate is less than the area of the light-emitting device projection.
Potential Applications: - Display apparatus - Lighting fixtures - Electronic signage
Problems Solved: - High luminous efficiency - Wavelength uniformity
Benefits: - Improved light emission - Enhanced display quality - Energy-efficient lighting solutions
Commercial Applications: Title: High-Efficiency Light-Emitting Devices for Displays and Lighting This technology can be used in various commercial applications such as display screens, lighting fixtures, and electronic signage. The high luminous efficiency and wavelength uniformity make it ideal for applications where quality lighting and display performance are essential.
Questions about Light-Emitting Devices: 1. How does the patterned bonding layer contribute to the high luminous efficiency of the device? 2. What are the advantages of having overlapping orthographic projections of the light-emitting units on the substrate?
Original Abstract Submitted
the present application provides a light-emitting device, a display apparatus, the light-emitting device including: a substrate; at least two light-emitting units, in a direction perpendicular to the plane where the substrate is located, orthographic projections of two adjacent light-emitting units on the substrate overlap; at least one patterned bonding layer, located between two adjacent light-emitting units, including a plurality of spaced bonding portions, the bonding portions are configured to be fixed and electrically connected to the two adjacent light-emitting units; the orthographic projection of the bonding portion on the substrate is within the orthographic projection of the light-emitting unit on the substrate, and the sum of the orthographic projection areas of all bonding portions on the substrate is less than the area of the orthographic projection of the light-emitting device on the substrate. embodiments of the present application provide a light-emitting device with high luminous efficiency and preferable wavelength uniformity.
