Recent research and development on 71‐in.‐diagonal color PDPs

— The World's first 71‐ and 76‐in.‐diagonal ACPDPs with full high‐definition resolution (1920 × 1080), a high luminance of 800 cd/m 2 , and a dark‐room contrast ratio of 1200:1 have been developed using a highly efficient barrier‐rib structure. Also a new MgO protective layer and a film‐type optical filter were developed to improve picture quality. To fabricate large‐sized panels over 70 in. on the diagonal, an improved uniform exposing technology for the patterning of electrodes, a green sheet method for the transparent dielectric layer, and a co‐processed bus and black‐matrix (CPBB) method were used.
