QD color filters for microLEDs
Press release 2019-09-06
New research project between Fraunhofer IAP and Korean Electronics Technology Institute (KETI)
Quantum dot-based color filters for micro-LEDs are one of the most promising future technologies for displays. This technology makes displays even more brilliant, more efficient and even thinner, compared to displays with conventional color filters. The Fraunhofer Institute for Applied Polymer Research IAP and KETI have started working together on the development of printed QD color filters microLEDs in the new research project "CoCoMe".
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 quantum effects to occur in the crystals. There is a whole class of materials, mostly semiconductor materials, that can be used to make quantum dots (QDs). By adjusting the size of a QD, its properties can be adjusted specifically for the desired application. As a result, the applications may vary widely.
