摘要:
A cathode-ray tube has an electron gun sealed in a neck in confronting relationship to the phosphor screen. The electron gun comprises a cathode assembly for emitting three electron beams, a main lens region for passing the electron beams therethrough, the main lens means including a high-voltage electrode or grid closer to the phosphor screen, and an assembly of electrostatic deflection plates, positioned closer to the phosphor screen than the high-voltage electrode, for converging the electron beams as one spot on the phosphor screen. An electrostatic convergence electrode assembly is disposed between the high-voltage electrode and the deflection plates. The electrostatic convergence electrode assembly may comprise three or two juxtaposed flat electrodes having electron beam passage holes. The voltages applied to the high-voltage electrode and the deflection plates are also applied selectively to the three or two electrodes of the electrostatic convergence electrode assembly for applying an astigmatic effect equally to the electron beams.
