    摘要: Device for projecting television pictures by means of an assembly of three television picture tubes with associated lens systems arranged in each other's proximity, including an integrated cooling system. The integrated cooling system has a liquid circuit comprising a first duct extending below the television picture tubes, which duct is in direct communication via passages with the lower ends of the flow spaces, and a second duct extending above the television picture tubes, which duct is in direct communication via passages with the upper ends of the flow spaces. The first and the second duct are connected via at least one connection duct which extends along an end the assembly constituted by the three television picture tubes.

    摘要: Projection television display tubes having an evacuated envelope (1) with a display window (4) which on its inside comprises a display screen (5) and in front of which a light permeable second window (6) is provided on its outside, a cooling liquid (16) flowing through the space (7) between the display window (4) and the second window (6) from at least one inlet aperture to at least one outlet aperture (17) namely by temperature differences in said cooling liquid. When in such a projection television display tube at the area of the windows (4, 6) and around the said space (7) a cooling jacket (8) is provided which comprises at least one duct (9) which transports the cooling liquid (6) from the outlet aperture(s) to the inlet aperture(s) of the said space, an effective cooling is obtained at a power between 12 and 25-30 W without external pipes or a heat exchanger. As a result of the circulation of the cooling liquid around the tube end at the area of the windows there is a good temperature compensation so that fewer stresses occur in the glass of the display tube.

    摘要: A projection television system comprising an array of three projection television display tubes (14) luminescing in red, green and blue, a focusing lens (16) associated with each tube and a display screen (12) on which the respective optical images are merged to form a single multicolored image. At least one of the display tubes (14) has a multilayer interference filter (46) between the phosphor (30) and the faceplate (20). In order to imprve the light output at the corners of the display screen (12), the cut-off angle of the first filter layers is varied between the center and the corners thereof, for example by increasing the optical thickness of the filter layers relative to the center.

    摘要: Projection television display device includes three monochrome projection television display tubes (20, 21, 22) each having a display screen (24, 25, 26) which is provided on the inside of the display window (23) and luminesces in a different color. Each tube has an optical axis extending perpendicularly from the center of the display screen, the optical axes (33, 34, 35) of the three display screens being co-planar. The axes (34, 33) of the display screens of the first and second tubes (20, 22) coincide and the axis (35) of the display window of the third tube (21) constitutes the main axis of the device, the axis being perpendicular to the two coincident axes (33, 34). Two flat dichroic intersecting reflective mirrors (27, 29) extend perpendicularly of the plane and through the point of intersection of the axes, each at an angle of 45.degree. with the main axis. The first mirror (27) reflects the image of the first display screen and the second mirror (29) reflects the image of the second display screen into the direction of the main axis and away from the third display screen, interference filters being disposed between the display screens and mirrors for passing the desired color of light. With interference filters disposed between the luminescent material of the display screens and the display windows, the reflection greatly increases for light rays constituting an angle of more than 20.degree. to 35.degree. with the normal of the filter. When there is substantially no transmission up to 90.degree., there is a gain in brightness by a factor of 1.5 to 2, a gain in contrast by more than a factor of 2 and also a considerable color improvement and reduction of color errors when the conventional green and blue phosphors are used.
