Abstract: 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.

Abstract: The invention relates to a shutter for an optical imaging system, e.g. a digital camera. The shutter comprises an interface between a transparent body and a capillary space. Light rays introduced to the active area of the interface are reflected by total internal reflection when the capillary space is filled with a gas. The light rays are transmitted through the interface when the capillary space is rapidly filled with a liquid. Thus, the light rays are either absorbed or reflected towards an image sensor, depending on the state of the shutter. The liquid is delivered to the capillary space through at least one duct which is positioned opposite the active area.
