摘要： The present invention provides a plasma display device for displaying a high quality image, and its driving method, with which the production cost and power consumption may be reduced and write errors may be suppressed. In the driving method, the length of the erase period D2 is T0+160 μsec, based on the number of sustain pulses being greater than or equal to 25 and less than 50 in the discharge sustain period C2. The length is set by a T1 setting unit according to the information on the number of the sustain pulses sent from a preprocessor in a driving unit, and a T1 table stored in a T1 table storage unit. The T1 setting unit sets T1=160 μsec referring to an extension time period T1 corresponding to the number of sustain pulses that is greater than or equal to 25 and less than 50 in the T1 table.

摘要： A method of driving a plasma display device that includes a plurality of scanning electrodes, a plurality of sustaining electrodes, and a plurality of data electrodes is such that, when m is any given integer, the data electrodes are applied with a negative polarity pulse when a voltage applied to the scanning electrodes gradually decreases during the initialization period, if a final pulse in a sustain period of an (m−1)-th subfield is applied to the scanning electrodes and an m-th subfield includes an initialization period. If the final pulse in the sustain period of the (m−1)-th subfield is applied to the sustaining electrodes and the m-th subfield includes the initialization period, the data electrodes are applied with a positive polarity pulse when a voltage applied to the scanning electrodes gradually increases during the initialization period.

摘要： An image display apparatus comprises, in a vacuum container whose inside is kept under vacuum, a fluorescent layer, an electron emission source having a plurality of electron sources, a deflecting electrode to deflect electron beams emitted from the electron emission source, and an ultrafocusing electrode to focus the electron beams and land the focused electron beams on predetermined positions of the fluorescent layer. The ultrafocusing electrode is arranged between the electron emission source and the fluorescent layer while the deflecting electrode is arranged between the electron emission source and the ultrafocusing electrode, so that the fluorescent layer is illuminated by the electron beams. If the landing position of the electron beam is deviated because of errors such as manufacturing errors in assembling the components into the image display apparatus, the deviation is minimized and an image display apparatus with high resolution can be obtained.

摘要： An AC plasma display device allows the display quality improved, to perform a write operation reliably and reduce a write operation period by reducing discharge delay at the write operation. Pairs of scan electrode and sustain electrode are arranged on a front substrate in parallel and covered by a dielectric layer. A protect film is formed on the dielectric layer. Data electrodes covered by an insulating layer are formed on a rear substrate. Partitions are located on the insulating layer in parallel with and between data electrodes. Conductive phosphor layers made of a mixture comprising an insulating phosphor material and a conductive material are formed from the surface of the insulating layer to each side of the partitions. Ignition gaps are defined between a surface of the protective film and peaks of the phosphor layer close to the surface.
