Abstract
Applications of digitally-controlled nano-mechanical structures are described, including both digital video and audio systems. For video systems, the nano-mechanical structures comprise resonant membrane spatial light modulators (SLMs), which are used in either transmissive mode or reflective mode operations to generate images. For audio systems, the nano-mechanical structures comprise resonant membrane spatial acoustic modulators (SAMs), which are used in reflective mode operations to generate sounds. For both SLMs and SAMs, a flexible support layer is deformed upon application of an electrical potential to the device, thus altering either the optical or acoustical characteristics of the device, respectively.
