Patent ID: 8207911

Claim:
A display device comprising: a plurality of plasma tube array units disposed adjacent to each other in a longitudinal direction of display electrodes thereof, each plasma tube array unit comprising a plurality of plasma tubes disposed adjacent to each other, each of the plasma tubes of a plasma tube array unit having a phosphor layer formed therein and being filled with discharge gas, each of the plasma tube array units further comprising a plurality of pairs of the display electrodes disposed on display surface sides of the plurality of plasma tubes of the plasma tube array unit and extending in a direction crossing a longitudinal direction of the plasma tubes of the plasma tube array unit, and a plurality of signal electrodes, each disposed on rear surfaces of the plurality of plasma tubes of the plasma tube array unit along the longitudinal direction of the respective plasma tubes of the plasma tube array unit; at least one scan driver circuit which applies a scan voltage and a sustain voltage to certain corresponding display electrodes of the respective pairs of display electrodes of two adjacent plasma tube array units at a position between the two adjacent plasma tube array units; and at least two sustain driver circuits which apply sustain voltages to other than the certain display electrodes of the respective pairs of display electrodes of the plurality of plasma tube array units, wherein the two sustain driver circuits apply the sustain voltages to the other than the certain display electrodes of the pairs of display electrodes of the two adjacent plasma tube array units on two respective outer sides of the two adjacent plasma tube array units.
