CRT ELECTRON GUN

摘要

The electron gun comprises a variable asymmetrical electrostatic prism lens by comprising an electrostatic deflection means in order to compensate the disagreement of the three electron beams around the screen due to the uniform magnetic field. The electrostatic deflection means comprises: the first electrostatic deflection electrode(20) connected to the first focusing electrode(7-1) electrically; and the second electrostatic deflection electrode(30) connected to the second focusing lens(7-2) electrically.
