  • Patent number: 7518575
    Abstract: A plasma display device that enables a stable address operation even in a high-speed drive so as to display an image of high definition and high quality. A PDP having discharge cells each provided with a scanning electrode and a sustaining electrode is driven by a method for displaying a frame of an image by repeating an address period, a discharge sustaining period, and a discharge suspend period. At least one initialization period that succeeds a discharge suspend period and in which the state of the wall charge in each discharge cell is initialized is provided. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period.

  • Patent number: 7075234
    Abstract: A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode (101a) and a second display electrode (101b) has a stepped shape, a film thickness of a discharge gap (Gap1) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L1, L2, L3 (L1>L2>L3). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.

  • Patent number: 7068244
    Abstract: 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.

  • Publication number: 20060132039
    Abstract: A gas discharge panel and method of providing a matrix of cells filled with a discharge gas and having plural pairs of display electrodes extending in a row direction of the matrix. Each pair of display electrodes comprise (a) two bus lines parallel to each other and extending in the row direction of the matrix, (b) one or more inner protrusions arranged within each cell on an inner side of one or both of the bus lines to protrude toward an inner side of an opposite bus line, and (c) one or more outer protrusions arranged to protrude from an outer side of one or both of the bus lines. A shortest gap between each pair of display electrodes is a gap between one of the bus lines and the inner protrusions on the opposite bus lines or a gap between the inner protrusions on both of the bus lines.

  • Patent number: 6788004
    Abstract: The object of the present invention is to greatly improve PDPs in luminance and luminous efficiency, compared to conventional PDPs. In order to achieve the object, the panel structure is set such that an equivalent field strength of at least 37V/cm·KPa is generated in selected discharge spaces in which the electric charge has been accumulated on their dielectric layer, when a discharge sustaining voltage is applied between a pair of display electrodes. To achieve such a high equivalent field strength as 37V/cm·KPa, adequate setting of the following factors of the panel structure is effective: a gap between a pair of display electrodes, a thickness and a permittivity of a dielectric layer, and an amount of Xe filled in discharge spaces.
