What They Say
Picosun, a maker of ALD machinery based in Finland, reported that a group from the National Yang Ming Chiao Tung University (NYCU) in Taiwan have boosted the EQE of 5 x 5?m microLEDs by 70% and 10 x 10?m microLEDs by 60% by applying Al2O3 passivation using ALD.
In addition, to achieve full color display, an inkjet printing to pattern quantum dots automatically has been developed at NYCU. The solution can considerably improve the precision of color pixels and satisfy the high-resolution requirements. Picosun ALD passivation technology was successfully used for preventing the quantum dots from photo-oxidation and degradation. After a 500 hours environmental reliability test, the color gamut remained at an ‘excellent level’.
What We Think
We have reached out to Picosun to try to get a link to the paper that explains this research. (BR)
