ABSTRACT:
The present is directed to a cathode ray tube having compensation plates for compensating the misconvergence of the paths of the beams of the tube resulting from the earth's magnetic fields, The cathode ray tube includes a neck portion and a funnel portion with a face plate, A gun is in the neck portion and is adapted to generate three electron beams and direct the beams toward the face plate. Purity convergence magnets are around the tube adjacent the neck, The compensation plates are between the purity convergence magnets and the tube and extend in parallel relation to the beam paths at opposite sides of the beams.
