Abstract
Embodiments of the invention include a display formed on an organic substrate and methods of forming such a device. According to an embodiment, an array of pixel mirrors may be formed on the organic substrate. For example, each of the pixel mirrors is actuatable about one or more axes out of the plane of the organic substrate. Additionally, embodiments of the invention may include an array of routing mirrors formed on the organic substrate. According to an embodiment, each of the routing mirrors is actuatable about two axes out of the plane of the organic substrate. In embodiments of the invention, a light source may be used for emitting light towards the array of routing mirrors. For example, light emitted from the light source may be reflected to one or more of the pixel mirrors by one of the routing mirrors.
