51‐4: QLED‐on‐Silicon Microdisplays
Digest of Technical Papers SID International Symposium, 2020In this paper, a 0.47 inch active‐matrix microdisplay with top‐emitting monochromatic quantum dot light‐emitting diode (QLED) array on silicon is demonstrated. A titanium nitride (TiN) is employed as the anode and the devices are fabricated by all‐solution process. The driver chip is designed especially for QLED microdisplay.

Paper No S14.1: OLEDs and QLEDs (Invited Paper)
SID Symposium Digest of Technical Papers, 2015Abstract The organic light‐emitting diode (OLED) technology is now maturing. The unique physics and chemistry of quantum dots (QDs) result in a wider color gamut and increased stability over organic dyes meaning they have significant potential over organics in light‐emitting devices.

P‐64: Improvement in Inkjet Printed Green QLED Efficiency
SID Symposium Digest of Technical Papers, 2021There is no doubt that TFB as HTL layer in QLED show predominance in presuming long lifetime devices, however, it is negatively affected by QD solvent in ink jet printing. Herein a thin layer of Tris(4‐carbazoyl‐9‐ylphenyl) amine (TCTA) was deposited between the QD and HTL to prevent QD solvent permeating into the TFB layer.

Effect of Structure and Thickness on the Electrical Characteristics of QLED Device
Applied Mechanics and Materials, 2014For the interface heterostructure between metal and organic layer of Quantum dot light-emitting diodes (QLED), tunneling injection model Fowler-Nordheim (F-N) was used to analyze the electrical characteristics of QLED. Through analyzing different thickness and the potential barrier of metal organic layer interface of QLED structure, simulation by ...

Role of Conjugated Structure of Cross-linkers in Patterned QLEDs
Nano LettersDirect optical lithography is a promising method for the high-resolution patterning of colloidal quantum dots (CQDs) in optoelectronic devices. However, this approach requires photo-cross-linkers that ensure strong chemical binding without degrading CQD ligands, while also supporting efficient charge transport.

Perovskite QLED with an external quantum efficiency of over 21% by modulating electronic transport
Science Bulletin, 2021Perovskite quantum-dot-based light-emitting diodes (QLEDs) are highly promising for future solid-state lightings and high-definition displays due to their excellent color purity. However, their device performance is easily affected by charge accumulation induced luminescence quenching due to imbalanced charge injection in the devices.
