摘要:
An insulation layer covering segment layers and a plurality of row electrodes arranged on a first substrate has, on its surface, first projections and second projections. The first projections have a shape and a height corresponding to those of the row electrode, and contacts partitions disposed on a second substrate. The second projections have a shape and a height corresponding to those of the segment layer. The partitions and the second projections constitute discharge barriers between columns, which prevents discharge interference from occurring between cells along the row electrodes.

摘要:
A plasma display panel includes row electrodes arranged on a first substrate, an insulation layer for covering the row electrodes, partitions each of which is placed in a boundary between columns of the second substrate and is continuous over an entire length of the column and a first projection that is formed on a surface of the insulation layer and has a shape and a height corresponding to those of the row electrode. In such a plasma display panel, a segment layer covered with the insulation layer is positioned in a manner to overlap with the partition in the first substrate and to avoid overlap with the row electrode and a second projection is formed on the surface of the insulation layer. The second projection has a shape and a height corresponding to those of the segment layer and constitutes a part of a discharge barrier between the columns.
摘要:
A method for driving a plasma display panel applies, within a subfield among the n subfields, a narrow-width pulse having a pulse width equal to or less than 2 &mgr;s to first electrodes in order to cause an erase discharge while terminating a discharge caused between the first and second electrodes, and applies a voltage pulse to third electrodes so that the voltage pulse falls at the same time as the narrow-width pulse falls.
摘要:
In a conventional method of driving a plasma display panel, for example, an auxiliary discharge is executed between an A electrode and a Y electrode to improve light-emission efficiency of a display discharge. However, since a phosphor layer is present between the A electrode and the Y electrode, the phosphor layer is exposed to a discharge, whereby there is a problem that its characteristic deteriorates. A method of driving a plasma display panel having a structure, in which at least three display electrodes X, Y, and Z used for a display discharge are provided to a display cell and no phosphor layer is formed between said display electrodes and a discharge space, the method comprising the steps of: varying a potential of at least one display electrode Z of said display electrodes during said display discharge; and making a potential of said at least one display electrode Z at a time of starting said display discharge different from that at a time of ending said display discharge.
摘要:
A Plasma Display Apparatus having common electrodes and address electrodes extending in a first direction and scan electrodes extending in a second direction perpendicular to the first direction, and each address electrode is aligned with a respective common electrode. A display cell is formed at a crossing portion of each common electrode and address electrode pair and each scan electrode. A lit state or an unlit state of each display cell is selected by applying, in individual succession, scan pulses to scan electrodes and selectively applying address pulses to the address electrodes. A sustain discharge is produced in each display cell selected to be lit by applying sustain pulses between the common electrodes and the scan electrodes.
摘要:
A plasma display includes address electrodes for scanning and addressing display cells, and scan electrodes for establishing an address discharge between the address electrodes and the scan electrodes by addressing. The display also includes common electrodes for establishing a sustain discharge between the scan electrodes and the common electrodes to display an image at the display cells, and a scan driver for supplying a voltage to the scan electrodes so as to scan display cells upon addressing during divided periods. Upon addressing, the scan driver varies the potential of a scan electrode adjacent to the scan electrode that corresponds to the addressed address electrode.
摘要:
In a reset period after a sustain discharge period, erase discharges are done by applying pulse voltages having different waveforms in the first erase discharge period for an ON cell turned on in the preceding sustain discharge period and in the second erase discharge period even for an OFF cell not turned on in the preceding sustain discharge period. Weak wall charges that could not completely be erased in the first erase discharge period, i.e., weak wall charges having been accumulated in the OFF cell under the influence of the ON cell can be erased in the second erase discharge period. This makes it possible to prevent an ON operation of the OFF cell that should not be turned on in the subsequent address period and sustain discharge period, and to improve the driving voltage margin.

The method of driving the plasma display, in which a discharge for the address action is caused to occur without fail even if the voltage of the address pulse is low and its width is narrow, has been disclosed. A display frame comprises plural subframes, the gradation display is attained by combining the lit subframes, each subframe comprises the reset period, the address period, and the sustain period, the reset voltage difference applied between the first electrode and the second electrode in the reset period and the address voltage difference applied between the first electrode and the second electrode in the address period can be set arbitrarily for each subframe, and the display frame includes plural subframes in which at least the reset voltage difference or the address voltage difference is different.
