QustomJet™

QustomJet™ is QustomDot's next-generation platform of cadmium-free, solvent-free quantum dot inks, purpose-built for industrial inkjet manufacturing. Designed for compatibility with standard piezoelectric print heads and UV-curing processes, the platform enables precise, high-uniformity quantum dot deposition while meeting the demanding requirements of modern display production.

QustomJet™ GEN2 combines optimized rheological properties, extended shelf stability, and long-term printing reliability with excellent photostability and high quantum efficiency. The formulation is engineered to maintain stable performance throughout the printing process and under prolonged illumination, supporting consistent device quality from pilot production to high-volume manufacturing.

Delivering vibrant, wide-colour-gamut displays without cadmium or organic solvents, QustomJet™ GEN2 provides display manufacturers with a scalable, environmentally responsible colour-conversion solution. The platform is pilot-ready, currently in customer qualification, and being scaled for commercial production, enabling a clear pathway from evaluation to mass manufacturing.

We engineer more than just the ink

We co-engineer the QD surface and the ink formulation together from the start — so every batch is optimized for direct on-chip integration.

Device-ready, out of the box

QD materials alone can't go directly onto a chip. QustomJet™ is formulated specifically for inkjet deposition — no extra processing, no physical separation from the light source, no workarounds.

Built on protected science

Our surface engineering methods, ligand library, and QustomJet™ Gen1 & Gen2 formulations are patent-protected. When you build with QustomDot, you build on a defensible technology foundation.
