A new delta arranged cell‐configured AC plasma display (DIA‐PDP) was proposed, and a prototype 46‐inch diagonal panel was fabricated. The DIA‐PDP has two features. The first feature is an improved luminous efficiency. This is possible because nondischarge cells are formed in the panel and a black layer is formed on these cells. Since the light from the discharge cells does not reach the nondischarge cells, even if a black layer is provided on the nondischarge cells, the panel reflectance can be reduced without lowering the luminance. When compared under the condition of a constant set reflectivity, the luminous efficiency improves. A 33% improvement over the conventional ratio was verified for the 46‐inch panel. The second feature is improved vertical resolution. In the delta configuration, the subpixels are arranged at half the pitch of the scanning lines. By combining this configuration with an interlaced drive, the vertical resolution can be improved. To increase the size of a PDP using a lattice rib, we introduced a new rib forming technology and improved the exhaust conductance. Previously, the manufacturing steps increased to form the exhaust path in the lattice rib. In the new rib forming method, the exhaust conductance was successfully improved without increasing the number of manufacturing steps only for forming the crossing ribs in the nondischarge cells and by producing height differences caused by thermal shrinkage. © 2004 Wiley Periodicals, Inc.
