Abstract:
1. A micro-shutter device, comprising: a membrane; a frame bonded to the membrane and comprising a receiving hole in a center portion, the receiving hole comprising a central hole and a plurality of edge holes disposed around the central hole; a transparent substrate bonded to the frame to encapsulate an optical fluid in the receiving hole; an actuator configured to bend regions corresponding to the plurality of edge holes on an outside of the membrane, so as to vary refractive power by bending of a periphery of the fluid lens to change a curvature of a fluid lens formed in the receiving hole; and a reflector spaced apart from the membrane and so configured such that light intensity is adjusted depending on the refractive power produced by changing the curvature of the fluid lens, and disposed to be in optical communication with the fluid lens.
