Micro LED as the innovative display technology is expected to replace TFT-LCD and OLED display in the near future with its high performance including high resolution, high contrast, self-emission, low power consumption and long life.
However, the technology still encounter several bottlenecks. The most challenging one for researchers and manufacturers is the notorious mass transfer process which requires bonding RGB LED chips to display backplane accurately and efficiently. The task also needs to tackle the issues caused by different chip materials such as breakable...

The Fraunhofer Institute for Applied Polymer Research IAP in Germany and Korea Electronics Technology Institute (KETI) announced their cooperation on the development of printed quantum dots (QD) color filters for Micro LED displays.
Dr. Youngsam Kim, President of KETI and Prof. Alexander Böker, Head of the Fraunhofer IAP seal the continuation of their cooperation.
Quantum dots are nanocrystals with optical, magnetic or electronic properties. These nanocrystals have a diameter of about 1-10 nm. The small diameter causes so-called qua...

Quantum Materials Corp announced that its cadmium-free quantum dots in a remote LED application successfully surpassed the 1000 hour continuous on-time durability test. The testing has been conducted with red and green quantum dots encapsulated in resin and mounted to blue emitting LED's (see diagram below), which are similar to the type of LED's used in standard LCD display back light units (BLU).

Lexington-based QD Vision, Inc., a spinoff of MIT, has developed Quantum LightTM Optic and the lamp is termed a quantum LED (QLED), to produce both lamps and downlighting fixtures that emulate the warm colors of an incandescent bulb but provide much greater light power and lamp life-time. The mechanism behind this extraordinary development is the redistribution of color by means of “quantum dots”. The ability to tune the color of a quantum dot offers a way to redistribute the harsh LED light by placing a specially designed layer of quantum dots in fron...

Japanese Nanoco Group has made great breakthrough on a 1kg batch of green cadmium-free quantum dots for a major Japanese corporation, triggering a US $2 million payment to Nanoco. The green quantum dots were produced at Nanoco's production facility in Runcorn, Cheshire. It marks major technical achievement by Nanoco because green dots are significantly more challenging than red ones due to their smaller size. The Japanese corporation plans to incorporate Nanoco's red and green quantum dots including the backlighting of LCD displays and LED-based general li...
