Abstract: Disclosed is a method of driving a plasma display panel and apparatus thereof enabling to minimize power consumption for driving the plasma display panel. 1. The present invention includes the steps of generating a reset discharge by supplying ramp waves so as to equalize cells in the plasma display panel in a reset period, supplying selected specific ones of the cells with a scan voltage pulse swinging between a lowest voltage levels of the reset discharge and a data pulse of a voltage level lowered as much as a negative voltage level of the scan voltage pulse, generating an address discharge by the scan voltage pulse and data pulse applied to the selected cells in an address period, and maintaining the address discharge for a sustain period.

Abstract: Device and method for driving a plasma display panel, wherein scanning pulses are progressively applied to the plurality of scanning/sustain electrode lines divided and driving in two or more than two blocks such that the scanning pulses are overlapped to each other, and first data pulses each with a first logic value and second data pulses each with a second logic value each having a data pulse width different from the first data pulse, are progressively applied to the plurality of address electrode lines, for causing address discharges at the plurality of discharge cells selectively, thereby permitting fast addressing, and minimizing power consumption.

Abstract: A PDP drive method capable of restraining the generation of contour noise and making to be high a brightness level. In the PDP drive method, discharging cells on the plasma display panel start simultaneously on a radio frequency discharge by row lines. Next, the radio frequency discharge, which is caused in each discharging cell on the row line, is erased by applying an erasing pulse corresponding to a brightness level of video to the discharging cells on a row line.

Abstract: A plasma display panel drive art capable of restraining a contour noise in a picture displayed on a PDP and reducing a maximum power consumption. The drive art allows one frame to be consisted of a plurality of sub fields each having a different weighting value for brightness so as to display a video signal of gray scale. The plurality of the sub fields are differently arranged along with a distribution of logical values in the video data for one frame, thereby dividing the one frame into a display interval and a non-display interval. Also, the plurality of the sub fields are equal to sub fields without a sub field having a least weighting value for the brightness.

Abstract: A plasma display panel driving method that is capable of improving the brightness in driving a plasma display panel by a sub-frame system. In the sub-frame system, a plurality of scanning lines spaced at an interval corresponding to a multiple of 2 in accordance with a gray scale are simultaneously selected to initiate a discharge. The plurality of scanning lines are sequentially addressed by an erasing discharge according to a data. The discharge of the addressed scanning lines is sustained by a certain period of sustaining pulses. The driving method performs an addressing of the plurality of scanning lines by dispersing it in a plurality of sustaining pulse periods. Accordingly, an addressing time per sustaining pulse is reduced to thereby increase a frequency of the sustaining pulse, so that the brightness of the PDP can be improved.

Abstract: A plasma display panel and a method and apparatus for driving the same that are capable of preventing miss-writing and improving discharge and light-emission efficiencies. In the panel, an upper substrate and a lower substrate are opposed to each other with having a plurality of discharge cells therebetween. A first upper electrode group includes at least one electrode having a desired width and is formed on the upper substrate. A second upper electrode group includes at least one electrode having a different width from the first upper electrode group and is formed on the upper substrate in such a manner to be adjacent to the first upper electrode group. A data electrode is provided on the lower substrate in such a manner to be perpendicular the first and second upper electrode group. In the method and apparatus, a short-path discharge occurs between two electrodes spaced at a small distance from each other, of electrodes included in the first and second upper electrode groups.

Abstract: A plasma display panel with a bilateral display function that is adaptive for displaying a picture in two directions and a driving apparatus thereof are disclosed. In the plasma display panel, a first plasma display panel displays a picture by a discharge. A second plasma display panel is installed such that its display face is opposed to that of the first plasma display panel. An optical shutter is installed between the first and second plasma display panels to transmit or shut off lights incident thereto from the first and second plasma display panels.

Abstract: An address driving method of a plasma display panel that permits a stable high-speed addressing. Tn the method, a data pulse is applied to an address electrode and applying a scanning pulse to a scanning electrode, to thereby generating an address discharge in the selected cell. Also, an auxiliary pulse is to an auxiliary electrode parallel to the address electrode, to thereby generating an auxiliary discharge. Accordingly, the auxiliary discharge is used to largely shorten a discharge delay time, thereby permitting a high-speed addressing. Also, the auxiliary pulse having the same polarity as the data pulse is applied to prevent an erroneous discharge between the auxiliary electrode and the data electrode.
