System and method for protecting microelectromechanical systems array using structurally reinforced back-plate

摘要

Disclosed is an electronic device utilizing interferometric modulation and a package of the device. The packaged device includes a substrate 101, an interferometric modulation display array 111 formed on the substrate 101, and a back-plate 130. The back-plate is placed over the display array 111 with a gap 124 between the back-plate and the display array. The device further includes reinforcing structures which are integrated with the back-plate. The reinforcing structures add stiffness to the back-plate. The back-plate may have a thickness varying along an edge thereof.
