    Abstract: The invention is notably directed to a transflective display device. The device comprises a set of pixels, wherein each of the pixels comprises a portion of bi-stable, phase change material, hereafter a PCM portion, having at least two reversibly switchable states, in which it has two different values of refractive index and/or optical absorption. The device further comprises one or more spacers, optically transmissive, and extending under PCM portions of the set of pixels. One or more reflectors extend under the one or more spacers. An energization structure is in thermal or electrical communication with the PCM portions, via the one or more spacers. Moreover, a display controller is configured to selectively energize, via the energization structure, PCM portions of the pixels, so as to reversibly switch a state of a PCM portion of any of the pixels from one of its reversibly switchable states to the other. A backlight unit is furthermore configured, in the device, to allow illumination of the PCM portions through the one or more spacers. The backlight unit is controlled by a backlight unit controller, which is configured for modulating one or more physical properties of light emitted from the backlight unit. The invention is further directed to related devices and methods of operation.

    Abstract: A transparent display device includes a transmissive light valve panel, a transparent plate and at least one light emitting assembly. The transmissive light valve panel has a display surface. The transparent plate is disposed with respect to the transmissive light valve panel to form an optical space between the transparent plate and the transmissive light valve panel. The at least one light emitting assembly is disposed beside the optical space and adapted to generate light into the optical space. A light pattern of the light emitted from the light emitting assembly and directed to the optical space has at least one maximum peak in an angular range of ±15° with respect to a direction parallel to the display surface of the transmissive light valve panel.

    Abstract: An electronic display which can be mounted above a paved surface in an outdoor environment. A surface or plate is placed behind the electronic display to define a gap where cooling air can be drawn through said gap in order to cool the electronic display. A plurality of ribs may be placed within the gap and in thermal communication with the electronic display. The density of the ribs may be varied according to the inlet and exhaust openings for the cooling air. The ribs may be placed at a higher density near the exhaust to account for the increase in temperature of the cooling air as it travels through the gap.

    Abstract: A display device comprises a plurality of pixels, each pixel having a portion (10) of a solid-state, phase-change material such as germanium-antimonium-telluride (GST) or vanadium dioxide, wherein the phase-change material can be reversibly brought into an amorphous state or a crystaline state and has a refractive index that is reversibly, electrically controllable. A plurality of electrodes (14, 16) are provided, at least two of which contact said portion of material (10). A controller (19) is provided that is adapted to apply at least one voltage to said material (10), via said electrodes (14, 16), to change said refractive index. An array of such portions of material can be arranged to make a pixellated display, for example a stereoscopic display of the volumetric type.
