Producing technicolor through brain-like electronic devices

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.
