  • Patent number: 6686897
    Abstract: A plasma display panel having scanning electrodes (Y) and sustaining electrodes (X) arranged in the form of XX-YY-XX-YY . . . , a rib structure vertically crossing the scanning electrodes (Y) and sustaining electrodes (X). The priming discharges during reset period does not occur in the display areas of the plasma display panel, the picture quality is assured from avoiding the emission of over-brightness in the reset period which enables the sequential gaseous discharge operations to proceed with smaller driving voltage.

  • Patent number: 6677714
    Abstract: A method for driving an alternating current plasma display panel (AC PDP) during a reset period is disclosed. Firstly, a first erase pulse, being positive in polarity and increasing in magnitude with time, is applied to a first electrode so as to remove wall charges from the pixel units. Then, a first priming pulse of negative polarity and a second priming pulse of positive polarity increases in magnitude with time and are respectively applied to the first electrode and a second electrode so as to produce the wall charges in the pixel units. Finally, a second erase pulse, being positive in polarity and increasing in magnitude with time, is applied to the first electrode so as to remove the redundant wall charges.

  • Patent number: 6677920
    Abstract: A PDP driving method, at the first timing point of a reset period, a global voltage difference is applied between the sustaining electrodes and the scanning electrodes, wherein the gaseous discharge occurs only in the non-display areas, called the dark areas. Because the discharge during reset period does not occur in the display areas, the picture quality is assured from avoiding the emission of over-brightness in the reset period which enables the sequential gaseous discharge operations to proceed with smaller driving voltage.

  • Patent number: 6633269
    Abstract: A driving method during the reset period of a plasma display, which includes a display panel with a plurality of display units for sealing the inert gas. Each display unit forms an equivalent capacitor and includes a first electrode, a second electrode, and a driving circuit that exerts voltage pulses to the display units to form wall charges on the surfaces of the two electrodes or to reduce the wall charges that have been formed. The method involves applying a first soft erase pulse on the first electrodes of the plurality of display units to reduce the wall charges of the plurality of the display units followed by applying a soft priming pulse on the second electrodes of the plurality of display units to re-generate the wall charges of the plurality of display units.

  • Publication number: 20030122735
    Abstract: A method for driving a plasma display panel (PDP). The PDP includes a first electrode and a second electrode. Initially provide the first electrode with a first voltage V1. Next, provide the second electrode with a second voltage V2 that is higher than the first voltage V1 during a first time interval. Then, provide the second electrode a third voltage V3 that is lower than the first voltage V1 during a second time interval. In the first time interval, a first voltage difference D1 between the first electrode and the second electrode equals the second voltage V2 minus the first voltage V1. During the second time interval, a second voltage difference D2 between the first electrode and the second electrode equals the third voltage V3 minus the first voltage V1.

  • Publication number: 20030042855
    Abstract: A method of driving a plasma display panel to improve display brightness and luminescent efficiency. In the sustain periods, the same driving signal is sent to the sustain electrode X as well as the address electrode Ai at the same time to achieve the desired volume discharge effect. In addition, the structure of PDPs is modified to raise firing voltages between these electrodes, preventing erasure of the data written in the address periods.

  • Patent number: 6483490
    Abstract: A method for providing the sustaining waveform to a selected discharge cell of a plasma display panel (PDP) is provided. First, a first pulse of a first voltage falls to a reference voltage is applied between sustain electrodes X and Y. Second, the voltage between electrodes X and Y remains at the reference voltage for a first period. Finally, a second pulse of a second voltage remains at the second voltage for a second period, and falls to the reference voltage is applied between sustain electrodes X and Y. The apparatus for providing the sustaining waveform to a selected discharge cell of a plasma display panel (PDP) includes a first energy recovery circuit, a second energy recovery circuit, a first capacitor and a first bi-directional switch, and a second capacitor and a second bi-directional switch. The first energy recovery circuit, which includes a first inductor and four switches, is connected to the first sustain electrode.
