The Progress of Advanced QD Technology in Next Generation Display

Quantum Dots (QDs) have been considered as key materials of the next generation display with wavelength-tunable, high color purity and high quantum yield properties.
After the QD film technology commercialized successfully, various new QD technologies are being developed, including QD on-chip LED, QD light guide plate(LGP), QD OLED, QD mini-LED, QD micro-LED and electroluminescence (EL) QLED.
QD mini-LED and QD micro-LED are among the most attractive products in the near future. QD mini-LED can upgrade the performance of general LCD to be able to compete with popular OLED display with nice contrast ratio, wider color gamut and better reliability. Then, full color micro-LED display can be fabricated with combining color-converted red and green QD layers and blue LED chips. The challenge of mass transferring and the cost of driving circuits can be largely reduced. Also, the disadvantage of the lower EQE of micro-sized red chips can be significantly improved by red QDs.
HsinLight and NTHU QLabs are devoted into new QD technology development and dedicated to collaborate with display supply chain partners to new QD application introduction and proof-of-concept. We would like to share you with our latest results in our new patented non-Cd QDs materials, QD color-converted micro-LED, inkjet printing EL QLED and the flexible and transparent QLED display.
