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.
