Abstract:
1. A method for changing the reflected colors of a pressure-sensitive array of display pixels, the method comprising: providing an electrical pressure-sensitive array of display pixels, each display pixel including a sealed chamber with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium; applying a first voltage potential between the first and second electrodes of each display pixel; receiving visible spectrum light at the top surface of each display pixel; with no pressure applied on the top surface of each display pixel, reflecting a first color from the incident spectrum of light; deforming the top surface of a first display pixel in response to an applied pressure; compressing the elastic polymer medium in the first display pixel; decreasing a metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel; and, in response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, changing the color reflected from the incident spectrum of light by a second display pixel, from the first color to second color, different than the first color.
