Quantum Dot Light‐emitting Diode Panel Process: Inkjet Printing

Inkjet printing (IJP) is a versatile, non‐contact method that uses piezoelectric energy to deposit ink droplets onto substrates, enabling precise pixel patterning up to about 300 ppi, crucial for fabricating quantum dot (QD) light‐emitting diode (QD‐LED) displays. With advances in QD materials and device engineering, IJP can produce cost‐effective, high‐performance QD‐LED displays, from wearable devices to tablets and large TVs. Initially targeting high‐end applications like premium TVs and professional monitors, inkjet‐printed QD‐LED displays are expected to gradually expand into mainstream markets as costs decline, positioning QD‐LED displays as a promising, next‐generation display solution with exceptional color accuracy, energy efficiency, and contrast ratio with deep black levels.
