Devices having MEMS displays
First Claim
1. A portable handheld device, comprising a housing, a display panel seated within the housing and having a light modulating layer with a plurality of transversely moveable shutters capable of modulating light by transversely moving the respective shutter through a path of a propagating ray of light to set a respective pixel in an on condition or an off condition, a control matrix coupled to the display panel for providing control over respective ones of the transversely moveable shutters for moving said transversely moveable shutters to modulate light, and a power source disposed within the housing and coupled to the light source and the controller.
