1. A display device, comprising:
- an array of interferometric modulators disposed on a first surface of a transparent substrate;
a carrier comprising a first surface and a second surface, wherein a first surface of the carrier is sealed to said transparent substrate to form a package encapsulating the interferometric modulator array; and
an outer device shell, wherein the carrier is disposed within the outer device shell, wherein a rear portion of the outer device shell is disposed on the opposite side of the carrier from the transparent substrate, wherein the rear portion of the outer device shell extends beyond the edges of the second surface of the carrier, and wherein the rigidity of the carrier is greater than the rigidity of the outer device shell.

Abstract
A MEMS-based display device is described, wherein an array of interferometric modulators are configured to reflect light through a transparent substrate. The transparent substrate is sealed to a backplate and the backplate can contain electronic circuitry for controlling the array of interferometric modulators. The backplate can provide physical support for device components, such as electronic components which can be used to control the state of the display. The backplate can also be utilized as a primary structural support for the device.
