Method and apparatus for reducing back-glass deflection in an interferometric modulator display device

摘要

Methods and apparatus for reducing back-glass deflection in an interferometric modulator display device are provided. In one embodiment, an interferometric modulator display is provided that includes a including a substrate, an optical stack formed on the substrate, a moveable reflective layer formed over the optical stack, and a backplate attached to the substrate. The moveable reflective layer includes one or more first posts extending therefrom, in which one or more of the first posts are operable to protect the moveable reflective layer by contacting at least a portion of the backplate if the backplate is deflected.
