摘要： A method of driving a gas discharge light-emitting device is disclosed which utilizes Townsend emission occurring transiently when discharge is started by applying power to a gas discharge light-emitting device so as to cause discharge and stopping the application of the power approximately when the ratio of radiation output of the discharge to the charged power starts decreasing.

摘要： A spacer of the present invention for use in an image display device, which has the spacer between a cathode substrate with a cold cathode electron emitting device formed thereon and an anode substrate with a phosphor formed thereon, comprises a phosphate glass having transition metal oxides as its main components, and a higher phosphate concentration layer at the spacer surface. A thickness of the higher phosphate concentration layer is suppressed to 0.5 μm or less. More preferably, the spacer has a water resistant conductive passivation layer formed on its surface. This suppresses the thickness of the higher phosphate concentration layer to a thinner level, so that the spacer is less likely to be charged thus reducing the deflection amount of electron beam. An image display device of the present invention using above spacer can apply a higher voltage to the anode substrate, thus increasing the image quality.

摘要： An electron gun for a color picture tube has beam generators for generating three electron beams and directing them toward the fluorescent screen along three paths which are parallel with each other on the same plane, and at least one pair of electrode surfaces each having three apertures centered with the three paths for forming independent main lenses so as to focus the electron beams on the fluorescent screen, the electrode surfaces being spaced apart from each other. Provided for the electrode surface are cylindrical shield members centered with the apertures and extending from the apertures in opposition to the opposing electrode surface. Outer ones of the cylindrical shield members have each an end surface inclined with respect to the center axis of the aperture so as to form inclined electric fields effective to converge the outer beams to one point to which the central beam converges.
