Embodiment Construction

[0013] An electron tube with an electron emitter or an electron gun. The electron emitter may be an electron gun anode or cathode or there is a photoelectric absorption surface around the center of the grid. For example, there is a photoelectric absorption surface near the screen surface in front of the A2 anode, and the electron emitter may be an electron gun. Insulated from the photoelectric absorbing surface. The photoelectric absorbing surface is connected with a resistor through a wire, and the other end of the resistor is connected with a ground wire through a wire to form a potential connection discharge circuit.

[0014] An electron tube has an electron emitter or an electron gun, the electron emitter is an anode or cathode of the electron gun, or there are photoelectric tubes around the center of the grid, and the electron emitter is the insulation between the electron gun and the photoelectric tube. The K pole (cathode) of the phototube is connected with the electron...

Abstract

The invention discloses a vacuum tube, comprising an electronic emitter. A photoelectric absorption face is arranged around the outer periphery of the center of the electronic emitter of the vacuum tube. The invention provides a technique for reducing useless light in a display and is especially suitable for a sphere focus style. The invention provides a technique which is good for the stable and continuous work of vacuum tube, good for prolonging service life and reducing corresponding electronic circuit load or the electronic circuit load of corresponding instruments and equipments.

Description

technical field [0001] This technology involves electron tubes Background technique [0002] Application number: 2004100902172 A spherical focus CRT display, spherical focus reduces screen brightness, but there is still a lot of useless light in the display, the present invention provides technology for reducing useless light in the display, especially suitable for spherical focus type. . [0003] The existing electronic tube has poor continuous working ability, short service life and heavy load on the corresponding electronic circuit. The invention provides technology that is beneficial to the stable operation of the electron tube, the continuous operation of the electron tube, the improvement of the service life, and the reduction of the load of the corresponding electronic circuit or the load of the corresponding electronic circuit of corresponding instruments and equipment. Contents of the invention [0004] An electron tube of the invention comprises: an electron em...
