A display and method of manufacture are described. The display may include a substrate including an array of pixels with each pixel including multiple subpixels, and each subpixel within a pixel is designed for a different color emission spectrum. An array of micro LED device pairs are mounted within each subpixel to provide redundancy. An array of wavelength conversion layers comprising phosphor particles are formed over the array of micro LED device pairs for tunable color emission spectrum.

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.

Reflective bank structures for light emitting devices are described. The reflective bank structure may include a substrate, an insulating layer on the substrate, and an array of bank openings in the insulating layer with each bank opening including a bottom surface and sidewalls. A reflective layer spans sidewalls of each of the bank openings in the insulating layer.

A method for manufacturing a light-emitting diode display is provided. The method includes pre-fixing first, second, and third light-emitting diodes on a light emitting unit production substrate to produce light-emitting units each including first, second, and third light-emitting diodes, first electrodes of the first, second, and third light-emitting diodes being connected to a sub-common electrode. The method also includes transferring and fixing the light-emitting units from the light-emitting unit production substrate to a display substrate to produce a light-emitting diode display including the light-emitting units which are arranged in a first direction and a second direction perpendicular to the first direction (i.e., arranged in a two-dimensional matrix).
