Abstract
A plasma display panel that is adapted to obtain a sufficient brightness as well as to enhance a discharging efficiency. In the panel, a plurality of discharging cells, each having an electrode to be driven by a radio frequency voltage signal, is arranged in the shape of a matrix. The discharging cells allow charged particles to swing while the radio frequency voltage signal is applied so that the charged particles in the discharging cells are not reduced. The swinging charged particles allow gaseous particles to be excited and transited continuously. In this way, the actual discharging period of the panel is almost equal to a predetermined discharging period. Also, since the discharging cell has a radio frequency discharge having physical characteristics almost equal to a positive column of a glow discharge, the energy efficiency and discharging efficiency of the panel increases with respect to prior art devices. Furthermore, an amount of vacuum ultraviolet rays created by the discharge is greater than in prior art devices. As a result, the panel obtains sufficient brightness.
