Abstract
A light modulator and method of forming the same is provided. The light modulator includes a membrane and a tuning electrode in spaced relation to the membrane. A light blocking fluid is received between the substrate and the tuning electrode and a light blocker is positioned between the tuning electrode and a central portion of the membrane. A pinning electrode is disposed between the light blocker and the membrane and is aligned with the central portion of the membrane. An electrostatic generator is configured to selectively apply an electrostatic force on the membrane causing the central portion of the membrane to deform towards pinning electrode causing the light blocking fluid to be displaced from between the membrane and the pinning electrode. A variable electrostatic generator is configured to selectively apply a variable electrostatic force on the membrane causing an outer portion of the membrane to deform towards the tuning electrode and causing the light blocking fluid to be displaced from between the outer portion of the membrane and the tuning electrode.
