Definitions

  • the invention relates to a method for producing the fluorescent screen according to the preamble of claim 1.
  • a color picture tube is known from EP-A1-0 104 834, in which a black matrix and the phosphors of the fluorescent screen are applied to the windshield by a printing process.
  • a mixture of a hot melt adhesive and graphite or the phosphors is used as printing paste.
  • the printing pastes are transferred from a heated vessel, in which they are in the liquid state, to engraved printing cylinders, which are also heated.
  • the print images in the engraved printing cylinders are applied to a flexible intermediate carrier by means of transfer rollers. First the printing paste with the graphite and then the printing pastes with the phosphors are placed one after the other on the intermediate carrier.
  • the intermediate carrier held by a frame is then positioned in the screen trough of the color picture tube.
  • a flexible piston presses the flexible intermediate support against the screen pan.
  • the black matrix and the phosphors now stick to the screen trough and the bulb and thus the intermediate carrier can be removed.
  • the usual treatment of the screen trough is carried out by first applying a lacquer and then an aluminum layer on the screen and then heating the organic components.
  • the invention is based on the object of specifying a simpler method for producing a fluorescent screen.
  • conventional screen troughs of color picture tubes can be provided with fluorescent screens.
  • the fluorescent screens can consist of fluorescent spots or strips. It is also possible to manufacture fluorescent screens with a black matrix.
  • the method is also suitable for the production of fluorescent screens from novel image display devices with flat windscreens.
  • the method is independent of whether or not a shadow mask is used in the image display device.
  • the method is described below using the example of a colored image display device with a flat front screen 1 and a luminescent screen 2 made of a black matrix M and the three usual phosphors red R, green G and blue B.
  • clichés 3M, 3R, 3B, 3G of the printing device Only four clichés 3M, 3R, 3B, 3G of the printing device are shown in section and a transmitter 4 in the form of a hemispherical tampon.
  • the clichés 3R, 3G and 3B are heated, which is indicated by a heating winding 5 in the clichés.
  • the printed image in the cliché 3M is filled in the usual way with a black ceramic glass ink Gm, which is removed from the transmitter 4 and printed on the front screen 1 (arrow 6).
  • the glass paint is then burned in, melting into the glass of the front pane and forming the black matrix M, which can no longer be removed.
  • Glass color No. 392016/64/5211 from Blythe Colors, Maastricht / Holland can be used as the ceramic glass color.
  • the printing pastes DR, DG and DB corresponding to the printing images in the clichés 3R, 3G and 3B are then printed one after the other into the spaces between the black matrix M.
  • printing pastes consist of a mixture of a thermoplastic hot-melt adhesive which is liquid at 60 to 80 ° C and evaporates without residue at more than 300 ° and the phosphors red, green and blue.
  • the hot melt adhesive belongs to the acrylate group, in particular compounds of the copolymeric acrylate styrenes can be used.
  • Such a hot melt adhesive is available from Blythe Colors, Maastricht / Holland.
  • the phosphor content is around 80%.
  • the printed images in the clichés 3R, 3G and 3B are filled with the heated and therefore liquid printing pastes, DR, DG and DB in the usual way. Since the clichés are heated, the printing pastes remain liquid and can be picked up in succession by the transmitter 4 and printed directly on the windscreen 1 which is at room temperature. This process takes place successively for each printing paste and is indicated by the arrows 7, 8 and 9.
  • the transfer device 4 can also be heated, which is caused by the heating winding 5.
  • One transmitter can also be used for printing the black matrix on the one hand and for printing the phosphors on the other hand. It is also possible to assign a transmitter to each cliché.
  • the surface of the transmitter or transmitters should have a hardness in the range from 2 to 20 Shore.
  • completely flat windscreens can also cylindrical tampons are used, which roll over the clichés and the windscreen. It is then possible to mount the clichés and the front screen on a temperature-compensated unit in order to absorb changes in length resulting from temperature differences. In particular, such a unit can be used to print the black matrix M.
  • the black matrix and the phosphor grid After the production of the black matrix and the phosphor grid, the usual painting and the application of an aluminum layer to the fluorescent screen. The organic substances of the fluorescent screen are then heated and the front screen with the fluorescent screen is ready for installation in the image display device.
  • the procedure can be such that a fluorescent screen is produced with uncorrected clichés and installed in an image display device.
  • this image display device is operated with a uniform pattern, the landing errors of the electron beams exciting the phosphors are measured in terms of direction and amount.
  • clichés are created in which the printed images are distorted according to the measured amount and against the measured direction.
  • the fluorescent screens produced with it then show a color-pure image.
