Study on the effect of size on InGaN red micro-LEDs [PDF]

Scientific Reports, 2021
AbstractIn this research, five sizes (100 × 100, 75 × 75, 50 × 50, 25 × 25, 10 × 10 µm2) of InGaN red micro-light emitting diode (LED) dies are produced using laser-based direct writing and maskless technology. It is observed that with increasing injection current, the smaller the size of the micro-LED, the more obvious the blue shift of the emission ...

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.

An overview on the principle of inkjet printing technique and its application in micro-display for augmented/virtual realities

Opto-Electronic Advances, 2022
Augmented reality (AR) and virtual reality (VR) are two novel display technologies that are under updates. The essential feature of AR/VR is the full-color display that requires high pixel densities.

Analysis of Factors Affecting Optical Performance of GaN-Based Micro-LEDs with Quantum Dots Films

Crystals, 2020
Optical performance in terms of light efficiency, color crosstalk and ambient contrast ratio were analyzed for blue GaN-based micro-light emitting diodes (micro-LEDs) combined with red/green quantum dots (QDs)-polymethyl methacrylate (PMMA) films.

High-Performance Core/Shell of ZnO/TiO₂ Nanowire with AgCl-Doped CdSe Quantum Dots Arrays as Electron Transport Layer for Perovskite Solar Cells

Molecules, 2020
Most previous studies of perovskite core/shell structures have been based on ZnO/TiO2 nanowires (NWs), which are not suitable for high photoelectric conversion efficiency. Here, core/shell ZnO/TiO2 NWs with AgCl-doped CdSe quantum dots were fabricated as

Micro‐LED Technologies and Applications [PDF]

Information Display, 2016
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 ...

Suppression of (0001) plane emission in GaInN/GaN multi-quantum nanowires for efficient micro-LEDs

Nanophotonics, 2022
GaInN/GaN multi-quantum-shell (MQS) nanowires (NWs) are gaining increasing attention as promising materials for developing highly efficient long-wavelength micro-light emitting diodes (LEDs). To improve the emission properties in GaInN/GaN MQS NWs, it is
