Abstract
A display includes a substrate, a matrix formed over the substrate, and thermomeltable material disposed in the matrix, having a transition temperature range above room temperature wherein the viscosity of the thermomeltable material decreases substantially from below to above the transition temperature range. The display also includes field-driven particles, immersed in the thermomeltable material, so that the field-driven particles change reflective densities in response to an applied electric field when the material is above the transition temperature range and is stable at temperatures below its transition temperature range, and heater(s) disposed in the display associated with the matrix for controlling the temperature of at least a portion of the matrix to control the response of the field-driven particles in the matrix.
