Patent ID: 7906907

Claim:
A Plasma Display Panel (PDP) comprising: a first substrate and a second substrate; a plurality of barrier ribs arranged between the first and second substrates to define discharge cells, the plurality of barrier ribs including first barrier ribs and second barrier ribs, said second barrier ribs including single walled barrier ribs that are parallel to each other and between each and every discharge cell, said first barrier ribs including single walled barrier ribs and double walled barrier ribs that are parallel to each other, said first barrier ribs are disposed perpendicular and connected to said second barrier ribs; a plurality of discharge electrodes arranged on portions of the panel corresponding to the barrier ribs to supply a discharge voltage to the discharge cells; and phosphor layers arranged in the discharge cells, wherein the single walled barrier ribs of the second barrier ribs have a uniform width, wherein the single walled barrier ribs of the first barrier ribs are disposed between adjacent discharge cells and the double walled barrier ribs of the first barrier ribs disposed between a pair of discharge cells with the single walled barrier ribs of the first barrier ribs between the double walled barrier ribs of the first barrier ribs, wherein the double walled barrier ribs of the first barrier ribs have a gap between the double walls discharging exhaust gas when the discharged cells are vacuumed sealed, and wherein the single walled barrier ribs of the first barrier ribs are wider at the point of contact with discharge cells having a red phosphor layer and narrower and of uniform width at the point of contact with discharge cells having a green or blue phosphor layer.
