Abstract
A display device includes an elongated display tube to be filled with a discharge gas and provided with a phosphor layer therein, a supporter in contact with the display tube for supporting the display tube, and a plurality of electrodes arranged on a surface of the supporter facing the display tube, for externally applying a voltage to the display tube for generating discharge in the display tube so as to perform a display. The supporter has a shape fitting the display tube whereby the electrode is in contact with the display tube along the surface shape of the display tube.
Claims14
A display device comprising:
- an elongated display tube to be filled with a discharge gas and provided with a phosphor layer therein, the display tube having a curved outer surface;
- a supporter having a curved support surface fitted with the curved outer surface of the display tube, to thereby support the display tube;
- and
- an electrode arranged on the curved support surface of the supporter and facing the curved outer surface of the display tube, for externally applying a voltage to the display tube to generate discharge in the display tube so as to perform a display,
- wherein the electrode is in contact with the display tube along the curved outer surface of the display tube over an entire length in an extension direction of the electrode along which the curved support surface of the supporter is fitted with the curved outer surface of the display tube.

A display device comprising:
- a tube array in which a plurality of elongated display tubes are arranged in parallel, each of said plurality of elongated tubes being filled with a discharge gas and provided with a phosphor layer and having a curved outer surface;
- a pair of supporters having curved outer surfaces fitted with the curved outer surfaces of the display tubes, to thereby support the tube array;
- a plurality of display electrode pairs arranged on the curved outer surface of one of the supporters and facing the curved outer surfaces of the display tubes of the tube array and in a direction crossing the display tubes, for externally applying voltage to each of the display tubes to generate a display discharge in each of the display tubes;
- and
- data electrodes arranged in parallel to the display tubes on a surface of the other of the supporters facing the tube array, for generating a selective discharge between the display electrodes and the data electrodes,
- wherein the display electrode pairs are in contact with the display tubes along the curved outer surfaces of the display tubes over an entire length in an extension direction of the display electrode pairs along which the curved outer surface of said one of the supporters is fitted with the curved outer surfaces of the display tubes.
