A 64 × 64 GaN Micro LED Monolithic Display Array: Fabrication and Light Crosstalk Analysis [PDF]

Micromachines
Monolithic micro LED display arrays show potential for application in small-area display modules, such as augmented reality (AR) displays. Due to the short distance between micro LEDs and the monolithic transparent substrate, a light crosstalk phenomenon

Understanding the Sidewall Passivation Effects in AlGaInP/GaInP Micro-LED [PDF]

Nanoscale Research Letters, 2022
The passivation effects of sulfur treatment and Al2O3 passivation for AlGaInP/GaInP red micro-light-emitting-diodes (LEDs) were investigated in terms of the external quantum efficiency (EQE) and the current density showing the peak EQE (J EQE, peak).

Series-Biased Micro-LED Array for Lighting, Detection, and Optical Communication [PDF]

Nanomaterials
Micro-LED arrays exhibit high brightness, a long lifespan, low power consumption, and a fast response speed. In this paper, we have proposed a series-biased micro-LED array by using a nitride layer with multi-quantum wells epitaxial on sapphire substrate.

Modulation of Nanowire Emitter Arrays Using Micro-LED Technology. [PDF]

ACS Nano
A scalable excitation platform for nanophotonic emitters using individually addressable micro-LED-on-CMOS arrays is demonstrated for the first time. Heterogeneous integration by transfer-printing of semiconductor nanowires was used for the deterministic assembly of the infrared emitters embedded in polymer optical waveguides with high yield and ...

Alleviating the crosstalk effect via a fine-moulded light-blocking matrix for colour-converted micro-LED display with a 122% NTSC gamut

Light: Advanced Manufacturing, 2022
One of the major challenges when fabricating high gamut colour-converted micro-light-emitting diodes (LEDs) displays is severe crosstalk effect among adjacent pixels because of the wide view-angle feature of micro-LED chips.
