  • Patent number: 8243230
    Abstract: An image display apparatus including a display device for displaying an image by emission of display light in a first direction; a scattering layer disposed in front of the display device, for scattering at least a portion of ambient light; a transparent plate-shaped light source, arranged parallel to the scattering layer and being optically coupled to the scattering layer. The plate-shaped light source may be a passive light source, in which case at least one light source is arranged along an edge of the plate-shaped light source. When the display device is ON, the scattering layer and the plate-shaped light source are transparent. When the display device is OFF, the scattering layer is scattering and the plate-shaped light source is ON.

  • Publication number: 20110050127
    Abstract: A lighting device (1401; 1402; 1403; 1404) comprises a semi-transparent plate-shaped light source (1409; 1400). The transparent plate-shaped light source may be a passive plate-shaped light source (1400) comprising a transparent light guide plate body (1410) with two substantially parallel main surfaces (1411; 1412), and wherein at least one of the main surfaces (1411; 1412) is provided with permanent obtrusions (1415). The obtrusions (1415) may be implemented as material portions projecting from the surface and/or as indentations recessed in the surface. The obtrusions (1415) may be arranged by sandblasting, preferably in a pattern of dots, wherein the dots may have sizes in the range between 20 and 200 ?m, preferably approximately 100 ?m, and wherein the dot density may be in the range between 5 and 500 dots/cm2.

  • Publication number: 20100014319
    Abstract: An image display apparatus (100) comprises: a display device (104) for displaying an image 900 by emission of display light (210) in a first direction; a scattering layer (902) disposed in front of the display device (104), for scattering at least a portion of ambient light (208); a transparent plate-shaped light source (950), arranged parallel to the scattering layer (902) and being optically coupled to the scattering layer (902). The plate-shaped light source (950) may be a passive light source, in which case at least one light source (967) is arranged along an edge of the plate-shaped light source (950). When the display device (104) is ON, the scattering layer (902) and the plate-shaped light source (950) are transparent. When the display device (104) is OFF, the scattering layer (902) is scattering and the plate-shaped light source (950) is ON.

  • Patent number: 6400078
    Abstract: The present invention relates to an image display panel (1) having a substrate (21) having at least one channel (31, 32, 33, 34, 35) comprising an ionizable gas mixture (51). The walls of the channels are provided with electrodes (37, 39) for selectively ionizing the ionizable gas mixture during operation. The display panel is provided with an exhaust box (55) and an exhaust tube (57) which are formed in one piece. The exhaust box (55) and exhaust tube (57) are provided at the back of the substrate (21) and extend in a plane parallel to the plane of the display panel.

  • Patent number: 4961023
    Abstract: Cathode ray tube having an electron gun which comprises a beam-shaping part and a focusing structure, which structure comprises a hollow tube with a helical electrically conducting glass-enamel layer on the inner surface. Together with the hollow tube, the components of the beam-shaping part are secured to axial mounting rods via metal supporting elements. The tube has a first and a second end face each of which is fixedly connected in one embodiment to a metal plate having a coaxial opening provided with a flange, which flange projects into the tube and is fused in an electrically conducting manner to the electrically conducting glass-enamel layer of the focusing structure.
