Abstract: An electron gun assembly for use particularly in a shadow-mask color television cathode-ray tube has a plurality of (usually three) electron emissive areas adjacent which an accelerating electrode or electrodes is or are arranged for producing respective substantially collimated electron beams from electrons emitted by said areas. The collimated beams pass through an apertured screening electrode or electrodes so arranged that the space extending up to the electron emissive areas is effectively screened from electric fields in the tube beyond the screening electrode or electrodes.
