| titleOfInvention | Phosphor screen preparation |
| abstract | A method of forming a plurality of different interspersed arrays of phosphors on the inside of a faceplate for a colour cathode ray tube, in which method a first mask is formed by irradiating an electron sensitive resist layer through a shadow mask with an electron gun arrangement in a demountable tube substantially at the same positions with respect of the arrays as the electron gun arrangement which will energise those arrays in the completed tube, a layer of light blocking material is formed over the first mask, subsidiary masks (sub-masks) are sequentially formed in the blocking layer for respective ones of the arrays of phosphors, each sub-mask being formed by irradiating electron beam resist covering the blocking layer through the shadow mask with an electron beam corresponding to the beam which will energise the associated array in use of the tube and removing the irradiated resist and underlying blocking layer, and phosphor is fixed in position in the sub mask. |
