Researchers Emulate Peacock's Tail For Advanced Color Display

Researchers at the University of Michigan, Ann Arbor have drawn inspiration from nature to envision advanced displays and color development for e-readers. This new technique allows the colors on screen to remain in place irrespective of the viewing angle.

Like a peacock reflects particular wavelengths of light at particular angles, the Researchers carefully created measured slits that would reflect colors. Narrow beams of light were captured at varying lengths which in turn reflected color. A device was constructed with nanoscale metallic grooves such that, when light hit the surface, electric field attracted specific wavelengths which were then sieved through the slits. The Researchers believe that the technique may find great purpose in advanced color e-readers where sunlight could be used as a light source to power color images, like e-inks, for example.

Currently, the technology has only been demonstrated with static images but researchers are working on making the advanced color display compatible with moving images as well.
