PHOSPHOR COATINGS FOR MICRO LIGHT-EMITTING DIODE (LED) DISPLAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240021587 titled 'PHOSPHOR COATINGS FOR MICRO LIGHT-EMITTING DIODE (LED) DISPLAYS
Simplified Explanation
The patent application describes a method for forming light-emitting diodes (LEDs) without phosphor deformation during the lamination process. The method involves forming LEDs on a backplane and applying a protective layer on the backplane. The protective layer is patterned to expose the sidewalls of the LEDs and the surface of the backplane. Each exposed area is filled with a color-shifting coating. The LEDs, backplane, protective layer, and color-shifting coating are then laminated between inner reinforcing layers and outer layers to create a display.
- LEDs are formed on a backplane.
- A protective layer is applied on the backplane.
- The protective layer is patterned to expose the sidewalls of the LEDs and the backplane surface.
- Color-shifting coating is filled into the exposed areas.
- The LEDs, backplane, protective layer, and color-shifting coating are laminated between inner reinforcing layers and outer layers.
- A display is created through this lamination process.
Potential Applications:
- Display technology for electronic devices such as smartphones, tablets, and televisions.
- Lighting technology for commercial and residential applications.
- Automotive lighting for headlights, taillights, and interior lighting.
Problems Solved:
- Prevents phosphor deformation during the lamination process, ensuring the quality and performance of the LEDs.
- Provides a protective layer to shield the LEDs and backplane from external factors.
- Enables the use of color-shifting coatings to enhance the visual effects of the LEDs.
Benefits:
- Improved durability and longevity of LEDs due to the protective layer.
- Enhanced visual effects and color-shifting capabilities.
- Cost-effective manufacturing process for producing displays with high-quality LEDs.
Original Abstract Submitted
aspects of the disclosure include light-emitting diodes (leds) formed without phosphor deformation during the lamination process. an exemplary method can include forming one or more leds on a backplane and forming a protective layer on the backplane. the protective layer can be patterned to define one or more trenches exposing sidewalls of a respective one led of the one or more leds and a surface of the backplane. each trench can be filled with a color-shifting coating. the method includes laminating the one or more leds, the backplane, the protective layer, and the color-shifting coating between one or more inner reinforcing layers and one or more outer layers to define a display.
