Patent ID: 7576901

Claim:
A method of manufacturing an interferometric display element, wherein the interferometric display element comprises a moveable reflective layer, a partially reflective layer, and a dielectric layer positioned between the moveable reflective layer and the partially reflective layer, the moveable reflective layer being suspended away from the partially reflective layer by one or more supports so as to define a cavity between the moveable reflective layer and the dielectric layer, the method comprising: selecting one or more characteristics of at least one of a support thickness, a support width, a dielectric layer thickness, and a moveable layer width, wherein the selected one or more characteristics define one or more of an actuation threshold, a relax threshold, and a voltage difference between the actuation and relax thresholds of the interferometric display element; optimizing the one or more characteristics for at least one of low power consumption, speed, and ease of manufacturing of the interferometric display element; and manufacturing the interferometric display element to include the selected one or more characteristics.
