Structural coloration promises to be the display
technology of the future as there is no fading—it does not use
dyes—and enables low-power displays without a strong external light
source. However, the disadvantage of this technique is that once a
device is made, it is impossible to change its properties so the
reproducible colors remain fixed. Recently, a POSTECH research team
has successfully obtained vivid colors by using semiconductor
chips—not dyes—made by mimicking the human brain
structure.
