Abstract
A display includes a plurality of light-emitting devices arranged as a matrix of pixels and an addressing circuit coupled to each respective light-emitting device. The addressing circuit includes a plurality of micromachined electromechanical (MEM) switches operable to control the plurality of light-emitting devices. Each MEM switch includes a cantilever beam and a control electrode spaced therefrom to deflect the cantilever beam electrostatically in order to close or open the switch.
