Abstract

1,146,140. Colour television tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 9 Jan., 1968 [12 Jan., 1967], No. 1253/68. Heading H1D. In a colour television tube of the shadow mask type the columns of holes in the shadow mask are at an angle of 80-85 degrees, preferably 83 degrees, to the line scanning direction to avoid the production of moire patterns if the tube is used for different line standards or if the scanning is non-linear. The electron gun or guns are also rotated so that they are aligned in the usual way with respect to the holes in the shadow mask.
