Title:
GAS DISCHARGE TUBE, AND METHOD OF FORMING ELECTRON EMISSION FILM IN GAS DISCHARGE TUBE
Document Type and Number:
Japanese Patent JP3929265
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas discharge tube of which, discharging property is improved and scatter of light emission movement between multiple light emission points is reduced by uniformly forming an electron emitting film on the inner surface of the gas discharge tube.
SOLUTION: The gas discharge tube comprises a plurality of light emitting part composed of at least two discharge electrodes formed to the outside of the tube, and an electron emitting film for the improvement of a discharging property, formed to the inside wall of the tube.
