Display device

Abstract

In a display device (10), a scan-driving circuit (702) supplies a scanning voltage, and then a maintaining voltage pulse, to one side of display electrodes (Y1,..., Yj,..., Yn) of each pair of a plurality of pairs of display electrodes in adjacent two units (314, 316) of a plurality of units, at least one of at least two maintaining voltage circuits supplies a maintaining voltage pulse potential to the other side of display electrodes (X1,..., Xj,..., Xn) of each pair of a plurality of pairs of display electrodes of at least one unit (502) at the most outside of a plurality of units.

Description

display device technical field The present invention relates to a large display device, in particular to an electrical connection to a drive circuit for display electrodes of a large display device formed of a plurality of plasma tube arrays having phosphor layers inside. Background technique In a plasma display panel (PDP), the plasma is discharged in a closed discharge space of a large number of small grids (cells) arranged vertically and horizontally, and the phosphor is excited to emit light by the 147nm ultraviolet light emitted from the discharge plasma. The cell space is formed between two overlapping sheets of flat glass. On the other hand, in a plasma tube array (PTA), a phosphor layer is formed in an elongated glass tube or a support member on which the phosphor layer is formed is inserted, and many grid spaces are formed in the tube. By arranging a large number of such plasma tubes side by side, a large display screen of, for example, 6 m×3 m can be formed. In...
