摘要： A display device comprising a light guide (12), a front plate (14), and an intermediate electromechanically operable foil (16). Two electrode layers (22, 23) are arranged on either side of the foil (16) to induce electrostatic forces on the foil (16) and to bring selected portions of the foil into contact with the light guide (12), thereby extracting light from the light guide (12). The second electrode layer (22) is arranged on the opposite side of the light guide (12) with reference to the foil (16), and separated from the light guide (12) by means of a refractive layer (28). As no electrode layer is required on the light guide itself, the light path of rays extracted from the light guide is cleaner, and the absorption of light is reduced. The light guide can have a thickness such that the light extracted from the light guide per unit length is sufficient to allow for line-at-a-time addressing.

摘要： The present invention provides a light collimating structure (102) comprising a first collimator (131) collimating light of a first property and at least one second collimator (141) collimating light of a second property, where the receiving areas (132, 142) of the collimators at least partly overlap and where the output areas (133, 143) of the collimators partly overlap. The at least two collimators act essentially independently from each other. Hence, the collimators can be positioned independently from each other, in order to provide good collimation for each of the light sources of the lighting unit. Further, the collimators may be designed independently from each other such that a good light mixing is obtained.

摘要： The present invention relates to a lighting system comprising a plurality of LEDs emitting light with different colors. The LEDs are provided with collimating optical components (51, 55) in order to emit collimated light beams. The LEDs are arranged in at least two layers (43, 45) and the collimating optical components (51) in the front layer are dichroic reflectors, so that they reflect the light from the associated front layer LED but transmit the light emitted from the rear layer behind. This eliminates or reduces the occurrence of colored edges around shadows on an illuminated surface.

摘要： A display device (500) having a plurality of picture cells (502) is controlled by adding a phase change to the regular cyclic inversion scheme. Thereby, it is possible to overcome the drawbacks of DC build-up due to, e.g., de-interlaced images and images comprising rotating symbols and “ticker tape”. The control involves receiving an image signal comprising image data relating to the picture cells. A respective electric field across each picture cell is controlled, in dependence on at least the image data, according to a first polarity inversion scheme where the polarity of the electric field is such that polarity inversion occurs at regular intervals, and according to a second polarity inversion scheme concurrent with said first polarity inversion scheme, where the polarity of the electric field such that polarity inversion occurs at pseudo-random intervals.

摘要： A waveguide (40; 51; 61), arranged to guide light from at least one light source (53a-c), the waveguide comprising at least one guiding edge (43; 50a-c; 60) adapted to contain the light in the waveguide (40; 51; 61), and an extraction edge (44; 50d) adapted to enable extraction of the light from the waveguide (40; 51; 61), wherein the guiding edge (43; 50a-c; 60) is configured to reflect the light on its way towards the extraction edge (44; 50d). The guiding edge (43; 50a-c; 60) is further configured such that a direction (xr1, Xr2) of reflection of a ray of light impinging on the guiding edge (43; 50a-c; 60), in a given direction (xi) of incidence relative to a general direction (X0) of extension of the guiding edge (43; 50a-c; 60), is dependent on a position (P1, P2) of incidence along the guiding edge (43; 50a-c; 60). The waveguide may be configured such that virtually no light is lost through back-scattering or unintentional extraction or outcoupling through the at least one guiding edge.
