US Patent 7567034 Plasma display panel with discharge spaces having sub-pixel units

A plasma display panel includes a plurality of first discharge spaces positioned between a front substrate and a rear substrate, and a plurality of sub-pixel units, each of the first discharge spaces having at least two of the sub-pixel units. Each of the first discharge spaces having at least two of the sub-pixel units increases the space available to discharge gas in each sub-pixel unit, thereby reducing a discharge voltage of the discharge gas in each sub-pixel unit and further decreasing an operating voltage and power consumption of the plasma display panel.
