Definitions

  • the present invention relates to a surface discharge type PDP (plasma display panel).
  • a surface-discharge type AC PDP is commercialized as a large-screen television display device.
  • the surface discharge type referred to here is a type in which first and second main electrodes serving as an anode and a cathode in a display discharge for ensuring brightness are arranged in parallel on a front or rear substrate.
  • a “three-electrode structure” in which address electrodes are arranged so as to intersect with a main electrode pair is widely known.
  • one of the main electrode pairs (second main electrode) is used as a scan electrode for row selection, and an address discharge is generated between the scan electrode and the address electrode.
  • Addressing for controlling wall charges is performed accordingly.
  • a lighting sustaining voltage having an alternating polarity is applied to the main electrode pair, a surface discharge along the substrate surface is generated only in cells having a predetermined wall charge.
  • FIG. 10 is a diagram showing the shape of a main electrode of a conventional PDP.
  • the main electrode X z is a laminate of a strip-shaped transparent conductive film 41 z extending straight in the row direction and a metal film 42 z having a small width that captures the conductivity.
  • the metal film 42z is arranged at the center of the transparent conductive film 41z in the column direction.
  • the main electrode Y z also includes a transparent conductive film 41 ⁇ ⁇ and a metal film 42 2.
  • main electrodes X z and Y z alternately arranged one by one, an adjacent main electrode X z and a main electrode Y z and an electrode pair for generating a strong surface discharge. And define a single line on the screen.
  • the main electrodes X z and Y z except for both ends of the array are each composed of two rows (odd rows and even rows).
  • the main electrodes X z and Y z at both ends are related to the display of one row.
  • the discharge space is divided into columns by a partition wall 29 ⁇ , and a column space, which is a discharge space for one column, is continuous across all rows.
  • the structure in the region surrounded by the adjacent partition wall 29 9 and the adjacent metal film 42 2 is the discharge cell (display element) C ⁇ .
  • the address electrode Az is arranged at the center of the column space.
  • An example of the driving method is as follows. Scan pulses are applied to the main electrode Yz one by one in the address period of either the odd field or the even field. Each time a scan pulse is applied, the potential of the odd-numbered main electrode X z and the even-numbered main electrode X are set so that an address discharge between the main electrodes occurs in a row used for display (eg, an odd row in an odd field). The potential of z is switched complementarily. During the display period following the paddle period, a lighting sustaining pulse is alternately applied to the main electrode X z and the main electrode Y z of a row used for display, and a row not used for display (for example, an even row in an odd field).
  • a lighting sustain pulse is applied to the main electrode Xz at the same timing as the main electrode Yz. That is, the potential change of the main electrode pair in the row not used for display is in phase. As a result, even if no partition is provided between the rows, the interference of discharge between the odd-numbered rows and the even-numbered rows is reduced.
  • the structure in which the column space is continuous over the entire length of the screen in the column direction has the advantages of manufacturing that the exhaust processing and the formation of the phosphor are easier than the structure in which the discharge space is divided for each cell.
  • there is an advantage in the driving aspect that the charge transfer between cells produces a priming effect.
  • a discharge in a certain row is excessively spread beyond an adjacent row and further to an adjacent row, that is, a crosstalk in a column direction occurs. This crosstalk is remarkable on a high-definition screen with a small line pitch.
  • An object of the present invention is to realize a stable display without erroneous discharge due to crosstalk.
  • the PDP to which the present invention is applied has a feature that each main electrode is divided in a column direction, and an electrode gap is provided at a boundary between discharge cells in the column direction. Electrode gap A pair of conductors sandwiched between them, that is, one part and the other part of the divided main electrode are controlled to the same potential. Since there is a force and a gap between the electrodes, the spread of the discharge through the electrodes is suppressed. The discharge generated between one part and the other main electrode is unlikely to spread to the other part. BRIEF DESCRIPTION OF THE FIGURES
