Abstract (en)

[origin: WO9917328A1] The invention relates to a method of applying a coating to a display window (38) of a color display device, said display window (38) being rotated about a rotary shaft (32) during said coating process. The method is characterized in that, during the application of the coating, the display window (38) is moved in a plane transverse to the rotary shaft (32). Preferably, the coating comprises a phosphor layer and/or a color filter layer. Preferably, three phosphor layers are provided and the display window is moved ina plane transverse to the rotary shaft (32) during the provision of the second and, in particular, the third phosphor layer. Preferably, the display window (38) is moved, during the provision of the coating, in such a manner that, during the rotation, the axis of symmetry of the display window (38) performs a translatory movement (40) or an eccentric movement about a further rotary shaft in a plane transverse to the rotary shaft (32). The rotational speed of the furter rotary shaft preferably ranges between 1 and 5 rpm. An apparatus for applying the phosphor pattern is described.
