Patent ID: 8350473

Claim:
A plasma display panel comprising: a front substrate on which a scan electrode and a sustain electrode are disposed; a rear substrate, on which an address electrode is disposed, positioned to be opposite to the front substrate; a barrier rib positioned between the front substrate and the rear substrate to partition a discharge cell; and a phosphor layer positioned in the discharge cell, the phosphor layer including a phosphor material and an additive material, wherein the phosphor layer includes a red phosphor layer emitting red light, a green phosphor layer emitting green light, and a blue phosphor layer emitting blue light, wherein a thickness of the blue phosphor layer is larger than a thickness of the red phosphor layer, wherein the blue phosphor layer includes a blue phosphor material and the red phosphor layer includes a red phosphor material, wherein a particle size of the blue phosphor material is larger than a particle size of the red phosphor material, wherein a height of the barrier rib is H, a pitch of the discharge cell is L, and a thickness of the phosphor layer measured at a location corresponding to one half of the height of the barrier rib (H/2) is larger than a thickness of the phosphor layer measured at a location corresponding to one half of the pitch of the discharge cell (L/2), wherein a ratio of the thickness of the blue phosphor layer to the thickness of the red phosphor layer lies in a range between 1.05 and 1.26, and the color temperature lies substantially in a range between 7,250K and 7,520K, wherein a percentage of a volume of the additive material based on a volume of the phosphor layer lies substantially in a range between 6% and 27%, and a discharge delay time is less than 0.63 μs, and wherein the discharge delay time is a time interval between a time point when a scan signal is supplied to the scan electrode and a data signal is supplied to the address electrode during an address period and a time point when an address discharge occurs between the scan electrode and the address electrode.
