  • Patent number: 8503064
    Abstract: An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.
