    摘要: In a sustain operation in an ALIS PDP device, a combination in which a basic first waveform and a second waveform in which a discharge peak is separated are mixed is applied. In the combination, the probability that the second waveform occurs successively is sufficiently reduced to less than 20%, and the number of times of sustain discharges of various intensities is made equal in the lines to be driven. By this means, the 2L nonuniformity can be prevented, and the deterioration of Vsmin can be reduced.

    摘要: A technique which relates to discharge in sustain operation of a PDP device and a driving waveform thereof, and which can improve luminous efficiency to achieve stability while reducing a possibility of failure of discharge is provided. In a generating operation of a sustain pulse in a sustain pulse generating circuit, after LU-ON (t1 to t2), a voltage applied on electrodes is raised up to a sufficiently-high voltage, namely, a sustain voltage according to an ON state of a CU circuit (t2 to t3), and discharge is started, CU is once turned OFF (t3), then a first discharge peak is formed (t11). Thereafter, CU is turned ON again before discharge is converged (t12) to raise a voltage value and form a second discharge peak (t14). Since a voltage Vi to start discharge is sufficiently high, a possibility of discharge failure is suppressed, and an effect of improvement in luminous efficiency is not ruined.

    摘要: A plasma display device is capable of creating a screen of high quality without generating half tone noise in the succeeding frames irrespective of the arrangement or the turn-on state of the subframes in a preceding frame that is being displayed. A picture of a frame is displayed on a plasma display device by combining a plurality of subframes SF1 and Sfn having different degrees of brightness. Each of the plurality of subframes SF1 and Sfn includes a totally writing and totally self-erasing period S1, an address period S2, a sustain discharge period S3, and a quiescent period S4 determined by a difference between the sum of the periods S1 to S3 and a period of a vertical synchronizing signal Vsync. A period S5 for imparting a discharge waveform different from the sustain discharge waveform applied across the electrodes is provided in the sustain discharge period S3 between the quiescent period S4 in the predetermined frame FM1 and the totally writing and totally self-erasing period S1 in the succeeding frame FM2.

    摘要: A PDP driving method for more reliably lighting cells that should be lit has been disclosed. The pulse duration of a scanning pulse can be varied depending on a scan line. The pulse duration of a scanning pulse to be applied to a scan line, to which numerous cells each having a high probability of becoming a flickering missing point because a priming effect is unavailable or small are connected, is made longer than that of a scanning pulse to be applied to the other scan lines. When a cell connected to the same address line and to an immediately preceding scan line or a scan line preceding the immediately preceding scan line is unlit, the pulse duration of a scanning pulse to be applied to a cell concerned is made longer. When a whole panel is noted, a scanning pulse having a long pulse duration is applied at least to the first scan bus line. If possible, the scanning pulse having a long pulse duration is applied to the second and third scan lines. As for the other scan lines, since they are influenced by display data, it is judged on the basis of display data to be displayed during the next cycle prior to the next cycle if each cell has a high probability of an addressing discharge failure.

    摘要: A plasma display panel has pairs of parallel first and second electrodes on a first substrate defining respective display lines and third electrodes on a second substrate, facing the first substrate, disposed orthogonally to and electrically separated from the first and second electrodes and defining discharge cells at intersections therewith. A controller defines reset, addressing and sustain discharge periods in a continuing succession. Drive circuits selectively apply voltages to the electrodes so as to produce in the discharge cells, in each rest period, reset discharges achieving self-erase discharge and charge distribution equalization, in each addressing period, discharges between the second and third electrodes in selected discharge cells in accordance with writing display data therein and, in each sustain discharge period, sustain discharge pulses between the first and second electrodes in the selected discharge cells thereby to emit light in accordance with the display data. The polarity of the potential difference between the first and second electrodes in each discharge period is opposite to that in each addressing period.
