This invention provides a plasma tube array-type display device and a luminance correcting method realizing reduced variations in luminance values of a plasma tube array. A gradient of the luminance value in the longitudinal direction of one plasma tube is calculated on the basis of the obtained luminance value at a plurality of positions in the longitudinal direction of at least one plasma tube. A difference of the luminance value of each plasma tube obtained at the same relative position. On the basis of the gradient of the luminance value and the difference of the luminance value of each plasma tube at the same relative position, a correction luminance value in each discharge cell in the longitudinal direction of each of the plurality of plasma tubes is calculated.

Plasma tube array-type display device and luminance correcting method

This invention provides a display device capable of maintaining a high image quality of a display image even when a plurality of plasma tube array-type display sub-modules is joined horizontally to one another. A display device comprises a plasma tube array-type display sub-module in which a plurality of plasma tubes, . . . , are arranged in parallel being held between an address electrode support sheet where address electrodes are formed and a display electrode support sheetwhere display electrodes are formed, wherein the plurality of plasma tube array-type display sub-modules, . . . , are joined horizontally to one another so that an interval between the adjacent plasma tube array-type display sub-modules, . . . , and a clearance between the adjacent plasma tubesare substantially equal.
