Purple LEDs to Replace Blue LEDs?

“It is only a matter of time before white LEDs using blue LED chips will disappear from the market,” said Shuji Nakamura at a forum on GaN technology in July organized by Nikkei Asian Review.

Nakamura shares a Nobel Prize in Physics with two Japanese inventors Isamu Akasaki and Hiroshi Amano for their invention of the blue LED. Yet, Nakamura’s recent remark completely derails his previous accomplishments. Industry insiders in China try to decode Nakamura’s comments to determine whether it reflects embedded flaws in blue LEDs design, or whether his motive is to promote Soraa’s purple LEDs.
