Abstract
An electrically-controllable color filter array based on a phase-change material, and an artificial vision system. The filter array includes a plurality of color filter units; each of the color filter units includes a metal layer, a bottom transparent conductive layer, a chalcogenide phase-change material layer, and a top transparent conductive layer; the red, green and blue filter function of each of the color filter units is adjusted according to the thickness of the bottom transparent conductive layer and the top transparent conductive layer; in the color filter units arranged in the array; the state transition of the chalcogenide phase-change material layer in each of the color filter units is realized by adjusting an electric pulse applied to the bit line and the word line where the electric pulse is present.
