摘要:
An electro-optical switch, which can be switched between a substantially transparent state and a scattering state on basis of respective applied voltages, is disclosed. The electro-optical switch has a reflection-voltage curve that is steep enough to allow multiplexing. The electro-optical switch comprises: a scattering layer (302) comprising a liquid crystal-polymer composite; and a reflective layer (306) for reflecting a portion of scattered light back towards the scattering layer (302).

An image display apparatus (100) is disclosed. The image display apparatus (100) comprises: a display device (104) for displaying an image, by emission of display light in a first direction; a scattering layer (102) disposed in front of the display device (104), for scattering a portion of the ambient light; and a reflective layer (106) disposed in between the display device (104) and the scattering layer (102) for reflecting a portion of the scattered ambient light into the first direction.
摘要:
The invention relates to a color display device for display a color image and a method of operating such display. The color display device is provided with a plurality of picture elements, two selectable light sources having different predetermined radiance spectra, color selection means which in combination with the selectable light sources is able to produce respective first and second primary colors on the display panel and control means arranged to select alternately one of the selectable light sources and to provide a portion of the picture elements with image information corresponding to the respective primary colors obtainable with the selected light source. The primary colors of the display device can be selected in a time sequential and space sequential way which enable a reduction of a color break-up.

The invention relates to an actuator device (400) comprising an active layer (410) having directly or indirectly a skin layer (420) on top that can be touched by when in use by a user. The configuration of the active layer (410) can controllably be changed in an extension direction (x, y), and the skin layer (420) comprises a plurality of elevations (E) and intermediate recesses (R). Due to its structure, the skin layer (420) does not hinder conformation changes of the active layer (410) in the extension direction, while it provides favorable tactile characteristics of the actuator device (400). The active layer (410) may particularly comprise an electroactive polymer (EAP). The skin layer (420) may be composed of a plurality of grains isolated from each other, or it may comprise a thin surface layer (421) that is stiffer than the active layer (410).

A micro system power supply (1) comprises a compartment (7), at least one ion sink void (51, 52) being separated from the compartment (7) by ion pervious separation means (61, 62), a first electrode (41) being arranged in the ion sink void, and a second electrode (42). Such a micro system power supply (1) allows to provide power for a micro system, such as, e.g., an implantable micro device, a MEMS, a bioMEMS, or the like, wherein the micro system power supply (1) can be comparably efficiently manufactured in a manner to be comparably environmentally friendly disposable.
