MICRO ASSEMBLED LED DISPLAYS AND LIGHTING ELEMENTS

摘要

The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

主权项

1. A micro-LED display, comprising:
a display substrate that is at least partially transparent; an array of color-conversion structures disposed on the display substrate, each color-conversion structure comprising a color-conversion material; and an array of micro-LEDs separate from the color-conversion structures, each micro-LED in the array of micro-LEDs disposed on a corresponding one of the color-conversion structure in the array of color-conversion structures.
