Abstract

An electronic device (100) of an embodiment of the invention is disclosed that at least partially displays a pixel of a display image. The device includes a first reflector (102) and a second reflector (104) defining an optical cavity therebetween that is selective of a visible wavelength at an intensity. The device includes a mechanism (112) to allow optical properties of the cavity to be varied such that the visible wavelength and/or the intensity are variably selectable in correspondence with the pixel of the displayable image. The device also includes one or more transparent deposited films (710), one or more absorbing layers (722), an integral micro-lens (804), and/or one or more anti-stiction bumps (908). The deposited films are over one of the reflectors, for self-packaging of the device. The absorbing layers are over one of the reflectors, to reduce undesired reflections. The integral micro-lens is over one of the reflectors, and the anti-stiction bumps are between the reflectors.
