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.

Image display apparatus, and disguising device

The present invention relates to an image display panel ( ) having a substrate ( ) having at least one channel ( ) comprising an ionizable gas mixture ( ). The walls of the channels are provided with electrodes ( ) for selectively ionizing the ionizable gas mixture during operation. The display panel is provided with an exhaust box ( ) and an exhaust tube ( ) which are formed in one piece. The exhaust box ( ) and exhaust tube ( ) are provided at the back of the substrate ( ) and extend in a plane parallel to the plane of the display panel.

Display panel

Display device, in particular a PALC device, having a plasma space provided with a capsule (,) comprising getter material for supplying guest material to the plasma, e.g. H,, HD, D,. The capsule remains closed until the critical high temperature processing has been finished.

Display device

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.
