Abstract

A technique of producing a control component for a reflective display device, comprising: forming an array of electronic switching devices; forming over said array of electronic switching devices an insulator region defining a controlled surface topography; and forming on the patterned surface of the insulator region by a conformal deposition technique a substantially planar array of reflective pixel conductors each independently controllable via a respective one of the array of electronic switching devices, wherein each pixel conductor exhibits specular reflection at a range of reflection angles relative to the plane of the array of pixel conductors for a given incident angle relative to the plane of the array of pixel conductors.
