A display device () comprises a reflective display () arranged to render a first image viewable through a viewing surface and a projection means (-) arranged to render a second image viewable in reflection on the viewing surface, the reflective display () and the projection means (-) being mounted on a common frame.

Illumination systems for reflective displays

A hybrid reflective-emissive display including an electrophoretic medium. The electrophoretic medium includes two types of oppositely-charged, and differently-colored, particles in a fluid. The electrophoretic medium is disposed between a front light-transmissive electrode and a rear electrode including a plurality of apertures, such as a hexagonal grid. The electrophoretic layer is optionally illuminated by a light source disposed on the opposite side of the rear electrode from the electrophoretic medium. A viewer can see either the first or second type of particle at the viewing surface, or one of the particles can be illuminated by the light source, thus emitting light the color of one of the particles.

Hybrid reflective-emissive display for use as a signal light

An energy harvesting electrophoretic display is disclosed comprising a photovoltaic cell that converts part of the incident light to electric current or voltage, wherein the electric current or voltage is used for the operation of the electrophoretic display upon the conversion or stored in a storage component to be used for the operation of the electrophoretic display.

Energy harvesting electro-optic displays

A method of operating an electro-optic display in which an image is scrolled across the display, and in which a clearing bar is provided between two portions of the image being scrolled, the clearing bar scrolling across in display in synchronization with said two portions of the image, the writing of the clearing bar being effected such that every pixel over which the clearing bar passes is rewritten.

Methods for operating electro-optic displays

An electro-optic display uses first and second drive schemes differing from each other, for example a slow gray scale drive scheme and a fast monochrome drive scheme. The display is first driven to a pre-determined transition image using the first drive scheme, then driven to a second image, different from the transition image, using the second drive scheme. The display is thereafter driven to the same transition image using the second drive scheme; and from thence to a third image, different from both the transition image and the second image, using the first drive scheme.
