The color mechanism of a peacock’s feathers could now be unlocked leading to the next generation of color displays on screens and their high resolution. The foundation that makes the feathers of a peacock look iridescent is actually structural color. This has been the field of study for many scientists as they have attempted to use it in everyday technology. Whatever research has been done so far has resulted in work done without the rainbow effect that makes the colors unstable based on the angle of the viewer.
University of Michigan Research Division has used the peacock feathers’ color mechanism in such a way that could bring about high resolution color display reflection. It may also impact data storage, cryptography and prevention of counterfeiting.
Structural coloration happens when the light is interfered as it travels through. It gets reflected off many small layers of a surface structure. It will, thus, differ to color production by chemical pigments that absorb parts of visible light.
Engineers have attempted to control the properties of structural color within reflective displays like e-book readers and electronic paper displays. The use of peacock feathers has helped the research team to capture some parts of a wavelength and it has helped to make the reflective hues hold true despite the changes in the angle of viewing.
This research could end up making colored e-books and electronic papers that may not need their own light for them to be visible clearly. This will also be in contrast to backlit screens of tablets, LCD televisions and computer monitors as they tend to be little difficult to read in daylight. In addition to this, the researchers feel that the technology can be used in various fields that may include cryptography, data storage and also invisible anti-counterfeiting techniques for documentation.
