Definitions

  • This document relates to a method of driving a plasma display panel.
  • a plasma display panel displays an image comprising a character or a graphic, by exciting phosphors using ultraviolet rays of a wavelength of 147 nm generated at the time of discharging an inert mixture gas of helium and xenon (He+Xe) or neon and xenon (Ne+Xe).
  • FIG. 1 is a perspective diagram illustrating a structure of a related art three-electrode alternate current surface discharge type plasma display panel (PDP).
  • PDP plasma display panel

  • the scan electrode 11 and the sustain electrode 12 each include metal bus electrodes 11b and 12b for reducing a resistance.
  • An upper dielectric layer 13a and a protective film 14 are layered on the upper substrate 10 comprising the scan electrode 11 and the sustain electrode 12.
  • Wall charges generated in the plasma discharge are accumulated on the upper dielectric layer 13a.
  • the protective film 14 prevents the upper dielectric layer 13a from being damaged by sputtering generated in the plasma discharge and also, enhances a secondary electron emission efficiency.
  • the protective film 14 uses oxide magnesium (MgO), in general.
  • a lower dielectric layer 13b and a barrier rib 21 are formed on the lower substrate 20 comprising the address electrode 22.
  • a phosphor layer 23 is coated on the lower dielectric layer 13b and the barrier rib 21.
  • the address electrode 22 is formed in the direction of intersecting with the scan electrode 11 and the sustain electrode 12.
  • the barrier rib 21 is formed in parallel with the address electrode 22, and prevents visible rays and the ultraviolet rays generated by the discharge from being leaked into an adjacent discharge cell.
  • the phosphor layer 23 is excited by the ultraviolet rays generated in the plasma discharge, and generates any one of Red, Green, and Blue visible rays.
  • An inert mixture gas such as helium and xenon (He+Xe) or neon and xenon (Ne+xe) for discharge is injected into a discharge space of a discharge cell provided between the upper/lower substrates 10 and 20 and the barrier rib 21.
  • the above driving method for the PDP is mainly classified into a selective writing method and a selective erasing method depending on whether the discharge cell selected by an address discharge for an address period emits light.
  • the selective writing method turns off an entire screen for a reset period and then, turns on the selected discharge cells for the address period.
  • the discharge cells selected by the address discharge are sustain discharged for a sustain period, thereby displaying an image.
  • FIG. 2 is a waveform diagram illustrating a related art driving method for a plasma display panel according to a selective writing method.
  • the PDP is driven by dividing a subfield into a reset period for initializing an entire screen, an address period for selecting a cell, a sustain period for sustaining a discharge of the selected cell, and an erase period for erasing wall charges.
  • all scan electrodes (Y) are concurrently applied a ramp-up waveform.
  • the ramp-up waveform induces a discharge within all cells of the entire screen.
  • positive (+) wall charges are accumulated on an address electrode (A) and a sustain electrode (Z), and negative (-) wall charges are accumulated on the scan electrode (Y).
  • a ramp-down waveform ramping down from a positive voltage lower than a peak voltage of the ramp-up waveform to base voltage (GND) or a specific negative voltage induces a weak erase discharge within the cells during a setdown period, thereby partially erasing excessive wall charges.

  • a high voltage sustain pulse is used for panel discharge in the driving method for the above plasma display panel. As shown in FIG. 2 , a voltage of +Vs based on the ground level voltage is used. In case where the discharge is initiated and sustained using the high voltage, it requires a high voltage Field Effect Transistor (FET). The use of the high voltage FET increases a price of the PDP, and causes a driving error when the PDP is driven at a high voltage, thereby increasing a possibility of inducing the erroneous discharge.
