Abstract: A screen comprises a support (1) with focusing elements; an active diffuser (3) is fixed to the support; it has an active face directed away from the support and located in the focal plane of the focusing elements of the support; the screen has an opaque layer (2) with a thickness less than 20 μm having openings adapted to let through the light focused by the focusing elements. This opaque layer is formed on the active face of the diffuser, or on an intermediate layer formed on the active layer of said diffuser. The openings in the opaque layer ensure the screen has a high contrast.

Abstract: The invention concerns a rear projection screen, comprising a support (22) with focusing elements such as microlenses (26) or lenticular elements, a holographic diffuser, and an opaque layer (36) with apertures (38) for allowing through the light focused by the microlenses. The light projected from the rear of the screen is concentrated by the microlenses (26) and passes through the opaque layer by the apertures (38). The holographic diffuser controls the directivity of the light. The incident light on the screen is absorbed by the opaque layer, such that the layer provides good transmittivity, high contrast, and controlled directivity owing to the holographic diffuser. The invention also concerns a method for making such a rear projection screen whereby the apertures in the opaque layer are formed by irradiating said layer or a preparatory material through the microlenses.

Abstract: A variable gain R.I.I. target is obtained by using an optical fibre board, whose face on the R.I.I. side has blind holes containing two types of granular luminescent materials having different luminous efficiencies and which are separated by a barrier layer. The electron beam from the R.I.I. photocathode is subject to two different accelerating voltages, the lower accelerating voltage exciting the luminescent material with the lower luminous efficiency and the higher accelerating voltage exciting the luminescent material with the higher luminous efficiency. Application to image intensifier tubes, used more specifically in radiology and fluoroscopy.

Abstract: A rear projection screen has successively, starting from the projector and moving outwards, a Fresnel lens (6), a surface diffuser (8), a thin support (10) bonded onto a thick substrate (24) provided with an outer anti-glare (26) layer. Light emitted by the projector (2) is collimated by the Fresnel lens (6). It passes through a diffuser (a) having an elongated radiation diagram with a horizontal major axis. This diffuser provides spreading of light in the horizontal plane, so as to provide a wide horizontal angle of view. The light leaving the diffuser is received on a support (10) with cylindrical focusing elements (18) substantially parallel to the major axis of the diffuser radiation diagram and an opaque layer (20) with apertures (22) adapted to allow light focused by the focusing elements to pass. As the focusing elements are parallel to the major axis of the diffuser, practically all the light projected is transmitted. Thanks to the presence of the focusing elements, the display screen has an appropriate vertical angle of view. The presence of the opaque layer ensures optimized contrast in view of the rearward position of the diffuser (8) with respect to the support (10).

Abstract: To produce a display screen, one forms an opaque layer (6) on a substrate (2) having focusing elements (4); this formation begins with the deposition of an ink or suspension on the face of the substrate directed away from the focusing elements; one then irradiates the opaque layer through the focusing elements (4) to form openings (8) in the opaque layer. This irradiation may be performed by laser, in such a way as to destroy the opaque layer at the focal points of said focusing elements. One then forms a diffuser layer in said openings (8) of the opaque layer (6) or on all of the opaque layer. The use of an ink or a suspension improves the adhesion of the opaque layer as well as the contrast of the screen.

Abstract: A high-efficiency cathodoluminescent screen for high-luminance cathode-ray tubes has a design which makes possible a considerable improvement of the luminance. The cathodoluminescent screen of the invention includes a glass substrate (11) carrying a luminescent screen (12) consisting of luminophor grains. According to a characteristic of the invention, an intermediate screen (15) is inserted between luminescent screen (12) and substrate (11), with the intermediate screen (15) having a refraction index n1 which is clearly greater than refraction index n0 of substrate (11). As a result of this arrangement, a considerable part of the light which penetrates intermediate layer (15) is reflected in the direction of luminescent layer (12), so that this light can then be rediffused to substrate (11), i.e., to use, with an emission indicatrix which is much more greatly concentrated on the axis than in the prior art.

Abstract: The luminescent screen comprises blocks having an optical transparency of less than 1. The blocks are placed between the grains of the first layer of luminescent material and the transparent substrate and have a cross-sectional area which is equal at a maximum to that of the grains. Said blocks are formed by means of a selective plasma etching operation in which the grains of the first layer of luminescent material are employed as a mask.
