Patent 7567367 was granted and assigned to LG on July, 2009 by the United States Patent and Trademark Office.
A micro mirror device and an array thereof are disclosed wherein an outer frame is formed at a position distanced from a mirror plate, thereby reducing a dynamic deformation of the mirror plate, preventing degradation of beam reflected from the mirror plate, and enabling to maintain a balance of the mirror plate. A frame structure supporting a diaphragm of a mirror plate is made to be thinner as it is distanced from a central axis of the mirror plate, thereby reducing a dynamic deformation of the mirror plate to a great extent and embodying the lightness of the device.
