Micro‐LED Technologies and Applications

Light‐emitting diodes (LEDs) offer extraordinary luminance, efficiency, and color quality, but to date are largely used in displays as backlights or packaged pixel elements in large‐area LED billboard displays. Building high‐performance emissive displays in a smaller form factor requires a new micro‐LED technology separate from what is used for large LED billboards. Several approaches have been proposed to isolate micro‐LED elements and integrate these micro‐LEDs into active‐matrix arrays. Technologies that use micro‐LEDs offer the potential for significantly increased luminance and efficiency, unlocking new possibilities in high dynamic range, augmented/mixed reality, projection, and non‐display light‐engine applications.
