The pulse width of scan pulses applied to some of a plurality of scan electrodes in which writing is performed and priming discharge is caused with the scanning of the scan electrodes is larger than the pulse width of scan pulses applied to the other scan electrodes in which writing is performed but no priming discharge is caused with the scanning of the scan electrodes.

Abstract: It is intended to prevent ink from leaking through the ink outlet of the ink rail while the printing press is at halt. To achieve this object, a motor control section 40 shown in FIG. 4 controls the rotation of a stepping motor 15 driving a plunger 13 and, every time the stepping motor 15 is stopped, the outer circumference 13c of the plunger 13 except a cut portion 13a blocks at least a discharge port 18, thereby enabling the pressure ink invading from an intake port 17 into the main hole 11 of a cylinder 12 to press the plunger 13 against the discharge port 18 opening into the inner circumferential face of the main hole 11.

Abstract: When a gas discharge panel is driven, a voltage is applied between scan and address electrode groups to perform set-up. The voltage waveform has four intervals. In a first interval, the voltage is raised in a short time (less than 10 ?s) to a first voltage, wherein 100 V?first voltage<starting voltage. Then, in a second interval, the voltage is raised to a second voltage no less than the starting voltage and with an absolute gradient smaller than that for the voltage rise in the first interval (no more than 9 V/?s). Next, in a third interval, the voltage is lowered in a short time (no more than 10 ?s) from the second voltage to a third voltage no more than the starting voltage. Following this, in a fourth interval, the voltage is lowered still further (for 100 ?s to 250 ?s) with a gradient smaller than that for the voltage fall in the third interval. The time occupied by the whole voltage waveform should be no more, than 360 ?s.

Abstract: The invention is a plasma display panel capable of stabilizing the addressing characteristics. A barrier rib is formed by longitudinal barrier ribs portion orthogonal to the scan electrodes and sustain electrodes on the front substrate, and side barrier rib portions crossing with these longitudinal barrier rib portions, to form cell spaces and form interstice portions between the cell spaces, and priming electrodes for producing a discharge between the front substrate and the rear substrate within the interstice portions are formed. Stable priming discharge is produced with certainty by the scan electrode and the priming electrode, hence decreasing the discharge time lag at the time of addressing and stabilizing the addressing characteristics.

Abstract: A plasma display apparatus has a waveform of a driving voltage supplied from a driver. The waveform has a sustaining period when a sustaining pulse is alternately applied to scanning electrodes and sustain electrodes for keeping discharge. Besides, the waveform has an erasing period when a ramp voltage pulse whose polarity differs from that of a sustaining pulse is applied to an electrode, which differs from an electrode where a last pulse of the sustaining pulse is applied. As a result, false discharge is prevented, and a stable image can be displayed.

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.

The PDP unit includes first display-electrode pairs each being a scan electrode and a sustain electrode arranged in a first order and second display-electrode pairs each being a scan electrode and a sustain electrode arranged in a second order opposite to the first order, arranged in parallel, thereby scan electrodes in adjacent pairs are adjacent to each other and sustain electrodes in adjacent pairs are adjacent to each other. The method includes: during an address period at driving, a first step of applying scan pulses to scan electrodes selected from the first display-electrode pairs in the first order direction; and a second step of applying scan pulses to scan electrodes selected from the second display-electrode pairs in the second order direction.

Abstract: 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.
