A gas discharge panel includes a first substrate and a second substrate. A plurality of display electrode pairs which are each made up of a sustain electrode and a scan electrode are formed on the first substrate, and the first substrate and the second substrate are set facing each other with a plurality of barrier ribs in between so as to form a plurality of cells. In this gas discharge panel, at least one of the sustain electrode and the scan electrode includes: a plurality of line parts; and a discharge developing part which makes a gap between adjacent line parts smaller in areas corresponding to channels between adjacent barrier ribs than in areas corresponding to the barrier ribs.

Gas dischargeable panel

The present invention aims to ensure luminosity while improving evacuation characteristics in a plasma display panel. First ribs () that separate a plurality of cells from each other and second ribs () are formed in stripe patterns so as to intersect with each other on a surface of a first substrate (), a surface of a second substrate opposes tops of the first ribs, and a height of the ribs at intersections () of the first and second ribs intersect is lower than other parts of the first ribs ().

Plasma display panel and manufacturing method therefor

Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realized by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

Plasma display panel driving method and plasma display panel apparatus capable of displaying high-quality images with high luminous efficiency

Set-up, write, sustain and erase pulses are variously applied to a plasma display panel using a staircase waveform in which the rising or falling portion is in at least two steps. These staircase waveforms can be realized-by adding at least two pulses. Use of such waveforms for the set-up, write and erase pulses improves contrast, and use for the sustain pulses reduces screen flicker and improves luminous efficiency. This is of particular use in driving high definition plasma display panels to achieve high image quality and high luminance.

A gas discharge panel capable of high-speed driving at a low drive voltage, while suppressing the occurrence of write errors in a write period, and a manufacturing method for the same. To achieve this, in the gas discharge panel of the present invention, a secondary gas formed from at least one of carbon dioxide, water vapor, oxygen and nitrogen is induced into discharge spacesevacuated until the residual gas pressure is 0.02 mPa or less, and an He&#x2014;Xe or Ne&#x2014;Xe rare gas (discharge gas) is induced into discharge spaces. The amount of the secondary gas included within discharge spaceswhen, for example, carbon dioxide is included therein, is suitably set in terms of both a discharge starting voltage and an electron emission ability, so that the partial pressure of the carbon dioxide is in a range of 0.05 mPa to 0.5 mPa inclusive.

Gas discharge panel and manufacturing method for the same

It is the object of the invention to provide a PDP apparatus and a driving method that can apply pulses at high speeds and can display high-definition, high-quality images by allowing discharge cells to emit light with high luminance and high efficiency. To achieve the object, the pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion, and the second waveform portion starts before a discharge delay time elapses from a start of the first waveform portion. Also to achieve the object, in a PDP having an electrode structure in which each electrode is divided into a plurality of line electrodes, the applied pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion.
