Hybrid Liquid Metal Cathode Enables High‐Performance Intrinsically Stretchable OLEDs

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
We report a hybrid liquid metal (Hyb‐LM) cathode engineered via selective rupture of liquid metal particles (LMPs), forming a bilayer architecture with a surface liquid metal (LM) layer and underlying LMP layer, which has benefits of both LM and LMPs.

Chromaticity-Adaptive Generalized Spatial Modulation for MIMO VLC With Multi-Color LEDs

IEEE Photonics Journal, 2019
In this paper, we propose a chromaticity-adaptive generalized spatial modulation (CA-GSM) method for multiple-input multiple-output (MIMO) visible light communication (VLC) systems with quadrichromatic LEDs (QLEDs).

Research Progress and Applications of Non‐Carrier‐Injection Electroluminescence

Advanced Electronic Materials, Volume 12, Issue 10, 25 May 2026.
Non‐carrier‐injection electroluminescence (NCI‐EL) uses AC fields and displacement currents to trigger light from internal charge reservoirs, enabling minimalist emitters with remotely coupled terminals. This review maps shared mechanisms across organics, GaN, quantum dots, and TMDCs, compares planar, interdigital, single‐terminal, and coaxial designs,

Intense Light Treatment of Inkjet‐Printed Metal Oxide Hole Injection Layer for Quantum Dot Light‐Emitting Diodes

Journal of the Society for Information Display, Volume 34, Issue 5, Page 335-342, May 2026.
An intense pulsed light (IPL) process enables low‐temperature activation of inkjet‐printed MoOX hole injection layers while preserving the hydrophobicity of pixel defining layers (PDLs). This approach overcomes process incompatibility in multilayer inkjet‐printed QLEDs, achieving uniform thin‐film morphology and stable pixel patterning.

Multi‐Functional Electrophoretic Deposition for Crosstalk‐Free, Ultra‐High‐Resolution Full‐Color QLEDs

Laser &Photonics Reviews, Volume 20, Issue 10, 22 May 2026.
A sequentially selective and high‐throughput QD patterning methodology via MEPD is herein presented for ultra‐high‐resolution microdisplays, ranging from tens of micrometers down to 500 nm without increasing process complexity. Taking into consideration electrical crosstalk between pixelated QLEDs, we have successfully demonstrated high‐resolution full‐

Surface‐Engineered ZnO Nanoparticles via Acetone Immersion for Charge‐Balanced High Resolution Full‐Color Organic Light Emitting Diode Displays

Small, Volume 22, Issue 29, 22 May 2026.
Acetone post‐immersion of OLEDs effectively passivates oxygen vacancies in the ZnO electron transport layer, reducing charge trapping and enhancing electron injection. This improves hole‐blocking at the interface and decreases exciton quenching in the emission layer, resulting in significantly enhanced electrical and optical device performance ...

Minimizing Defects in Blue‐Emitting ZnSeTe Quantum Dots Using ZnF2 Throughout Core and Shell Growth

Small, Volume 22, Issue 30, 27 May 2026.
Near‐unity photoluminescence quantum yield (PLQY = 0.98) in blue ZnSeTe quantum dots is achieved by integrating ZnF2 throughout all growth stages. ZnF2 performs two key functions: generating HF in situ for structural defect removal and simultaneously promoting X‐ and Z‐type ligand attachment for effective surface passivation.

Multilayer Soft Photonic Arrays Inspired by Cephalopod Skin for High‐Density, Independent, and Multimodal Actuation

Advanced Functional Materials, Volume 36, Issue 31, 16 April 2026.
A vertically stacked, DEA‐driven photonic array inspired by cephalopod skin, featuring highly crystalline colloidal crystal gels with vivid color, low FWHM and scalability is presented. The multilayer design removes lateral pixel interference, achieving near‐100% fill factor with fully independent RGB actuation.
