Multi-state shutter assemblies having segmented drive electrode sets
Abstract:
This disclosure provides systems, methods and apparatus incorporating display elements having light modulators that can operate in more than two states. In some implementations, the light modulator assembly includes an electrostatic actuator that includes a load electrode coupled to a shutter and a drive electrode set positioned proximate to the load electrode. The drive electrode set includes a plurality of discrete portions that are configured to drive the light modulator assembly to a plurality of different light modulator states. In some such implementations, the portions of the drive electrode set are positioned opposite to corresponding regions of the load electrode. In some implementations, the portions are arranged such that the portions are configured to electrostatically engage with adjacent regions of the load electrode.
