Zhijing Nanotech Quantum Dot backlight units (QD-BLUs) using perovskite quantum-dot film (PQDF)

Posted by Charbax – June 17, 2018

Zhijing Nanotech from Beijing, China, develops next-gen quantum dot backlight units (QD-BLUs) for wide color gamut QLCD technology, which contains perovskite quantum-dot film (PQDF) as a primary light-conversion component. The PQDF exhibits high light conversion efficiency, narrow emission peak, high integration and low cost. During Display Week, they demonstrated the wide-color gamut PQDF-LCD TV prototype, which was achieved by combining the blue-light emitting diode (LED) chip, red K2SiF6:Mn4+ (KSF) phosphor, and green PQDF as RGB backlight sources. The luminance is above 500 nits.

Display Week’s I-Zone, sponsored by E Ink, is a unique exhibition-within-the-exhibition filled with demos and prototypes from around the world. Every year, dozens of applicants submit their pre-market and emerging products to compete for a free booth where they can share their inventions with buyers, manufacturers, potential partners, industry leaders and thousands of attendees.
