Abstract

An arc tube array-type display device includes an arc tube array, a supporting member, a plurality of display electrodes, a plurality of scan electrodes, and a plurality of address electrodes. The arc tube array has a plurality of arc tubes arranged side by side. Each of the arc tubes has a discharging gas sealed therein. The supporting member supports the arc tube array. The plurality of display electrodes are arranged at an adjacent portion between the arc tubes, and generate an opposing discharge inside the arc tube by applying voltages to each of the arc tubes from both of the side faces. The plurality of scan electrodes are arranged on the display surface side of the arc tube in a stripe form in a direction intersecting the longitudinal direction of the arc tube so as to form light-emitting areas at intersecting portions against the arc tubes. The plurality of address electrodes are used for selecting light-emitting areas arranged on the back surface side of the respective arc tubes.

Claims (17)

1. An arc tube array-type display device comprising:

an arc tube array in which a plurality of arc tubes are arranged side by side, each of the arc tubes having a discharging gas sealed therein;

a supporting member that is made in contact with at least one of a display surface side and a back surface side of the arc tube array so as to support the arc tube array;

a plurality of display electrodes that are arranged at an adjacent portion between the arc tubes, and generate an opposing discharge inside the arc tube by applying voltages to each of the arc tubes from both of the adjacent portions;

a plurality of scan electrodes that are arranged on the display surface side of the arc tube in a stripe form in a direction intersecting the longitudinal direction of the arc tube so as to form light-emitting areas at intersecting portions against the arc tubes; and

a plurality of address electrodes used for selecting light-emitting areas arranged on the back surface side of the respective arc tubes, wherein

each of the display electrodes comprises light-emitting and non-light-emitting areas, the light-emitting areas being wider than the non-light-emitting areas and the non-light-emitting areas being formed on a position close to the back surface of the arc tube array,

each of the address electrodes comprises light-emitting and non-light-emitting areas, the light-emitting areas being wider than the non-light-emitting areas, and

the light-emitting areas of the display electrodes project from the supporting member.

2. The arc tube array-type display device according to claim 1 , wherein the display electrodes are formed on both sides in the outside wall face of the arc tube.

3. The arc tube array-type display device according to claim 1 ,

wherein each of the display electrodes is formed on one of both sides in the outside wall face of the arc tube, and

the adjacent arc tubes commonly possess each of the display electrodes located between the adjacent arc tubes.

4. The arc tube array-type display device according to claim 1 ,

wherein the supporting member is constituted by a front-surface side supporting member placed on the display surface side of the arc tube array and a back-surface side supporting member placed on the back surface side of the arc tube array,

the scan electrodes are formed on a face opposing to the arc tube of the front-surface side supporting member, and

the address electrodes are formed on a face opposing to the arc tube of the back-surface side supporting member.
