    Abstract: In order to form a fluorescent surface on a panel (9) of a colour cathode ray tube, a light source is placed at a number of positions (0 2 , 0, Q 1 ) and exposed at each position to a photoresist film (10) on the inside surface of the panel to form prescribed stripe width patterns using a transmission light intensity distribution formed by superposed plural Fresnel diffraction waveforms. Exposure is effected in the different positions via different correction lens systems (12, 28,, 28 2 ) selected to correspond to the exposure at the various light source positions and the absolute value of the transmission light intensity distribution and the derivative (dl/dx) of the transmission light intensity distribution at positions corresponding to the edge of the stripe width pattern are optimised over the entire inside surface of the panel.

    Abstract: A cathode-ray tube capable of forming an image of high quality by forming a phosphor dot pattern on the internal surface of the face panel with high shape accuracy and positional accuracy. The phosphor dot pattern is formed as follows. Exposing light is passed through a swinging lens for correction. The lens has small flat and curved portions so that a lattice-like bright-line pattern is produced behind the lens due to the steps between the adjacent flat and curved portions. The pattern is projected onto the whole photosensitive film on the internal side of the face panel through a shadow mask. Using the exposed photosensitive film as a mask, a phosphor dot pattern is formed on the internal side of the face panel. The screen of the cathode-ray tube is made up of more than one million picture elements of the phosphor dot pattern. The rate of change in luminance of the screen is less than +/-0.15 %.

    Abstract: A color cathode-ray tube having at least a front panel, a funnel and an electron gun. A luminescent film is provided on the front panel. The luminescent film is produced in this manner. Red-light-emitting, green-light-emitting, and blue-light-emitting phosphor layers are repetitively laminated with nonluminescent layers interleaved. The laminate is cut along its thickness into films and baked. This makes it possible to efficiently produce a cathode-ray tube having a color luminescent screen that features very high accuracy and high resolution, and that can be adapted to small CRTs.

    Abstract: A color display device is provided with a black-matrix layer, a phosphor pattern and color-filter layers. The rheological behavior of the suspension and/or the evaporation of volatile constituents is influenced by the topology of the color-filter layers, with, in particular, projecting color-filter layers exerting an influence. As a result, variations in thickness between the phosphor layers occur. By reducing the differences in height between a projecting color-filter layer and the black-matrix layer, the variations in thickness between the phosphor layers are reduced and hence the quality of the picture displayed is improved.

    Abstract: A method for creating a faceplate of a display provides a faceplate substrate with a faceplate interior side and a faceplate exterior side. A plurality of barriers are formed on the faceplate interior side, with the barriers defining a plurality of subpixel volumes. Phosphor containing photopolymerizable material mixtures of red, green and blue, are deposited into subpixel volumes, and create a faceplate interior side/phosphor interface. At least a portion of the phosphor containing photopolymerizable material mixture is exposed with sufficient actinic light through the faceplate interior side/phosphor interface to polymerize a selected depth of the phosphor containing photopolymerizable material mixture in the subpixel volumes, and form a polymerized phosphor containing material in a plurality of subpixel volumes. Non-polymerized phosphor containing photopolymerizable material is removed from the polymerized phosphor containing material.
