Stripe ribs make address discharge more stable than box ribs due presumably to the priming particles provided from vertically neighboring cells. Discharge deactivation film (DDF) of low γi material, which selectively covers an MgO surface so as to fold the relative bus lines, improves the address discharge response dramatically because DDF pushes the address discharge area closer to the surface discharge gap. A TiO2 under-layer for phosphor also significantly improves the response. Presumably the electrification characteristic of the layer, which may depends on the surface treatment onto the TiO2 grains, contributes much to the formation of an electric field for generating face-to-face address discharge. Using these in our 46-in. HD-PDP, Xe15% (by volume) is acceptable with respect to practical driving for TV use if the dielectric layer is arranged thinly to prevent extremely high sustain voltage. Thus white peak luminance and luminous efficiency of 1220 cd/m2 and 2.16 lm/W, respectively, can be achieved.
