Definitions

  • This invention relates to a plasma display apparatus and a driving method thereof.
  • a plasma display panel applies a reset pulse for initializing a discharge cell, an address pulse for selecting a cell to be discharged, and a sustain pulse for sustaining a discharge of a discharge cell to each electrode by a predetermined number of times according to a gray level value of each subfield and allows a phosphor to emit visible light by a gas discharge generating through applying of the pulses.
  • the PDP repeats resetting, addressing, and sustaining in each subfield constituting a frame, and it is necessary to apply an erase pulse for removing wall charges remaining in each electrode side before the each subfield starts in order to improve PDP driving characteristics.
  • FIG. 1 is a view illustrating a structure of a general PDP.
  • the PDP comprises a front panel 100 and a rear panel 110 that are disposed apart by a predetermined distance and coupled in parallel to each other.
  • the front panel 100 is arranged with a plurality of sustain electrode pairs in which a scan electrode 102 and a sustain electrode 103 are formed in pairs on a front glass 101, which is a display surface through which an image is displayed.
  • the rear panel 110 has a plurality of address electrodes 113 arranged to intersect the plurality of sustain electrode pairs on a rear glass 111 constituting a rear surface.
  • the front panel 100 comprises pairs of the scan electrode 102 and the sustain electrode 103, which have a transparent electrode (a) made of transparent indium-tin-oxide (ITO) and a bus electrode (b) made of metal, for performing a mutual discharge in one discharge cell and sustaining emission of the cell.
  • the scan electrode 102 and the sustain electrode 103 are covered with at least one upper dielectric layer 104 that limits a discharge current and that insulates each electrode pair.
  • a protective layer 105 deposited with magnesium oxide (MgO) is formed on the upper dielectric layer 104 to facilitate a discharge condition.
  • the rear panel 110 comprises stripe-type (or well-type) barrier ribs 112, which are arranged in parallel, for forming a plurality of discharge spaces i.e., discharge cells.
  • a plurality of address electrodes 113 for generating vacuum ultraviolet radiation by performing an address discharge is arranged in parallel to the barrier ribs 112. Red (R), green (G) and blue (B) phosphors 114 that emit visible light for displaying an image at an address discharge are selectively coated over an upper surface of the rear panel 110.
  • a lower dielectric layer 115 for protecting the address electrode 113 is formed between the address electrode 113 and the phosphor 114.
  • FIG. 2 A method of representing an image gray level in the PDP is shown in FIG. 2 .
  • FIG. 2 is a diagram illustrating a method of representing an image gray level of a general PDP.
  • a frame is divided into several subfields having different respective amounts of time of light emitting, and each subfield is again divided into a respective reset period (RPD) for initializing all cells, an address period (APD) for selecting a cell to be discharged, and a sustain period (SPD) for representing a gray level depending on the respective number of times of discharge.
  • RPD reset period
  • APD address period
  • SPD sustain period
  • the duration of the reset period in one subfield is equal to the duration of the reset periods in the other subfields.
  • the duration of the address period in one subfield is equal to the duration of the address periods in the other subfields.
  • An address discharge for selecting a cell to be discharged is generated by the voltage difference between an address electrode and a transparent electrode, which is a scan electrode.
  • a driving waveform according to a driving method of the PDP is shown in FIG. 3 .
  • FIG. 3 is a diagram illustrating a driving waveform according to a driving method of a conventional PDP.
  • the PDP is divided into a reset period for initializing all cells, an address period for selecting a cell to be discharged, and a sustain period for sustaining a discharge of the selected cell for driving.
  • ramp-up waveforms are simultaneously applied to all scan electrodes (Y).
  • a discharge is generated within discharge cells of an entire screen by the ramp-up waveform.
  • the setup discharge causes positive wall charges to become accumulated on address electrodes (X) and sustain electrodes (Z) and negative wall charges to become accumulated on scan electrodes (Y).
  • a ramp-down waveform (ramp-down) that falls from a positive voltage lower than a peak voltage of the ramp-up waveform up to a ground (GND) voltage or a negative voltage level is applied, whereby a weak erase discharge is generated within the discharge cells and thus some of excessively formed wall charges are erased.
  • Wall charges sufficient for a stable address discharge due to the setdown discharge are uniformly retained within the discharge cells.
  • the sustain electrodes (Z) are supplied with a positive DC voltage (Zdc) so that an erroneous discharge is not generated between the sustain electrode (Z) and the scan electrode (Y) by reducing the voltage difference between the sustain electrode (Z) and the scan electrode (Y) during the setdown period and the address period.
  • Zdc positive DC voltage
  • sustain pulses (Sus) are alternately applied to the scan electrodes (Y) and the sustain electrodes (Z).
  • a sustain discharge i.e., a display discharge is generated between the scan electrodes (Y) and the sustain electrodes (Z) whenever each sustain pulse is applied as the sustain pulse and the wall voltage within the discharge cell are added.
  • an erase ramp waveform (Ramp-ers) having a narrow pulse width and a low voltage level is applied to the sustain electrodes (Z) to erase wall charges remaining within the discharge cells of the entire screen.
  • the plasma display apparatus alternately applies positive sustain pulses (sus) to the scan electrode (Y) side and the sustain electrode (Z) side during a sustain period
  • positive ions accumulate on the address electrode (X) side having a relatively low potential difference.
  • positive ions relatively heavier than electrons, effect ion bombardment of a phosphor layer (114 of FIG. 1 ) of a rear panel in which address electrodes (X) are formed, the lifetime of the plasma display apparatus may be shortened.
  • FIG. 4 is a diagram illustrating a driving waveform according to a negative sustain driving method of a conventional PDP.
  • a negative sustain pulse (-sus) is alternately applied to the scan electrode (Y) and the sustain electrode (Z) during a sustain period.
  • the lifetime of a plasma display apparatus can be extended and a discharge firing voltage can be lowered.
  • the negative sustain pulse (-sus) can be applied to a long gap structure, which is a new electrode structure.
  • a conventional interval between electrodes has been about 60 to 80 ⁇ m, but a structure for increasing the amount of light passing through the gap between electrodes by widening the gaps between electrodes to more than 150 ⁇ m, is referred to as a long gap structure. According to the long gap structure, as the amount of light emitted from a phosphor increases, light emitting efficiency can be improved.
  • the long gap structure is generally formed by reducing the area of a conventional electrode, i.e., an ITO area. According to the long gap structure, when a discharge is generated between the scan electrode and the sustain electrode, an opposed discharge is generated if the sustain voltage is set to ground voltage.
  • the opposed discharge is a discharge between the scan electrode and the data electrode. That is, in the long gap structure, a discharge is generated due to the voltage difference between the scan electrode and the data electrode earlier than a discharge between the scan electrode and the sustain electrode when a voltage difference is generated between the sustain electrode set to a ground voltage and the scan electrode. As describe above, the long gap structure is driven on the assumption of the generation of an opposed discharge. Accordingly, a driving method, different from a driving method in a conventional surface discharge mode, is required.
