Abstract: The invention relates to a three-dimensional auto-stereoscopic display aimed at, but not restricted to domestic television applications. In this display different viewing directions in the horizontal plane are created by projecting an image on a 2D display through lenticular lenses and onto horizontal lines of to the 3D screen. These lines are scanned along the display by means of a single rotating mirror. The proposed embodiment has a large viewing angle and shows a picture with realistic parallax and perspective. Compared to other known three-dimensional displays, it uses existing components, has a simple construction and is light efficient.

Abstract: A display unit comprising electro-wetting pixels (1300) is provided. The inventive pixels (1300) provide bistable or multi-stable pixel states and thus facilitates passive matrix addressing. For this purpose an additional electrode (1305) is arranged for each multi-stable state. Consequently, each pixel comprises one counter electrode (1306) and at least one pair of address and retain electrodes (1304, 1305). In order to activate a pixel, an address potential is applied to the address and retain electrodes (1304, 1305) in relation to the counter electrode (1306), and in order to deactivate a pixel the potential is removed. In order to retain a current pixel state a retain potential is applied to only the retain electrode (1305) in relation to the counter electrode (1306); the current pixel state, be it active or passive, will then be preserved and the retain potential configuration thus provides a bistable pixel state.

Abstract: A display device is provided with electron beam guiding channels (10). A channel (10) receives an electron beam (EB) and guides the beam (EB) parallel to a luminescent display screen (40). The electron beam (EB) is extractable from the channel (10), after which the beam (EB) impinges on the display screen (40). Electrode means (11, 12, 13) defining an electric potential in the channel (10) are provided for guiding and extracting the electron beam (EB). The electrode means (11, 12, 13) are arranged in such a way that in the channel (10), the electron beam (EB) is focused in a transverse direction being perpendicular to the channel (10) and parallel to the display screen (40). Thus, the electron transmission of the beam guiding channel (10) can be particularly high.
