Summary:The specification and drawings present a new method, apparatus and software product for modulation of the optical intensity using electro-wetting (EW) diffraction gratings in the electronic devices with an electrical control signal. The EW diffraction gratings can be components of an element (e.g., a display) of the electronic device. Applications may include but are not limited to color displays, projection displays, front illuminating displays, field sequential displays, auto-stereoscopic displays, etc. Also, applications in areas other than displays are possible.
