The Korea Advanced Institute of Science and Technology (KAIST) announced on May 7 that its research team formerly led by the late biomolecular engineering professor Yang Seung-man developed a photolithography-based micro-patterning technique which can accelerate the commercialization of photonic crystals.
The photonic crystal pattern developed at this time is a key material for next-generation reflective displays and allows images to be viewed clearly even under sunlight. It uses no additional light sources at all, and thus can be used for days after one full charge.
“When semiconductor processing techniques are combined with this photonic crystal patterning technique, an earlier-than-expected commercialization of photonic crystals will be ensured,” said KAIST biomolecular engineering professor Kim Shin-hyeon, co-author of the research. He continued, “Then, it will be used as a core optical material constituting advanced reflective color display devices with extremely low power consumption.”
The research results were published in the April 16 edition of Advanced Materials, a renowned scientific journal covering materials science.
