摘要： A plasma display panel for color displaying is provided which is so formed that it is possible to improve the contrast and color purity of the display panel while at the same time controlling the brightness drop to a minimum level. In particular, it is possible to effectively inhibit a contrast drop usually caused due to neon emission. In practice, an optical filter capable of attenuating light components each having a wavelength within a range of 560-590 nm is provided on the front side of the plasma display panel. Such plasma display panel includes an electric discharge space containing a discharge gas mainly comprising neon gas and xenon gas.

摘要： A plasma display panel driving method capable of improving the contrast while preventing spurious borders. Only in the first subfield, a writing discharge is selectively produced only in discharge cells except for those serving to display a luminance level “0” to initialize these discharge cells to a light emitting cell state. Then, only in one of the remaining subfields except for the first subfield, an erasure discharge is selectively produced in the discharge cells remaining in the light emitting cell state in accordance with pixel data, causing the discharge cells to transition to a non-light emitting cell state. Only the discharge cells remaining in the light emitting cell state are driven to emit light the number of light emissions allocated thereto corresponding to a weighting factor applied to the subfield.

摘要： A radio frequency plasma display panel that is capable of reducing a height of a barrier rib and a frequency of a radio frequency signal as well as improving a light-emission efficiency. In the radio frequency plasma display panel, a plurality of discharge cells are arranged in a matrix pattern. Each of the discharge cells has upper and lower substrates. First and second address electrodes are provided on at least one of the upper and lower substrates to generate an address discharge. Barrier ribs are provided between the upper and lower substrates to define a discharge space. First and second radio frequency electrodes are provided the respective barrier ribs opposed to each other to generate a radio frequency sustaining discharge. Accordingly, the radio frequency sustaining discharge is generated between the first and second radio frequency electrodes within the respective barrier ribs for a long time, so that a height of the barrier ribs and a frequency of a radio frequency signal can be lowered.
