Embodiment Construction

[0019] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing exemplary embodiments of the present invention.

[0020] figure 1 It is a perspective view of a plasma display panel (PDP). refer to figure 1 , the PDP includes sustain electrode pairs formed on an upper substrate 10 and address electrodes 22 formed on a lower substrate 20 . The sustain electrode pair includes scan electrodes 11 and sustain electrodes 12 .

[0021] The scan electrode 11 may include a transparent electrode 11a and a bus electrode 11b, and the sustain electrode 12 may include a transparent electrode 12a and a bus electrode 12b. The transparent electrodes 11a and 12a may be formed using indium tin oxide (ITO). The bus electrodes 11b and 12b may be formed of a metal such as silver (Ag) or chromium (Cr), a chromium / copper / chromium (Cr / Cu / Cr) stack, or a chromium / aluminum / chromium (Cr / Al / Cr) stack. . The bus electrodes 11b and 12b are dispo...

Abstract

A plasma display device and a method of driving a plasma display panel (PDP) are provided. The plasma display device includes an upper substrate on which a plurality of first electrodes and a plurality of second electrodes respectively corresponding to the first electrodes are formed; and a lower substrate on which a plurality of third electrodes are formed, wherein the first electrodes are respectively 100 [mu]m or more distant apart from the second electrodes, and during a reset period, a voltage that gradually increases is applied to the first electrodes, and at the same time, a positive bias voltage is applied to the third electrodes. Therefore, it is possible to reduce the power consumption of a PDP by driving a PDP including a scan electrode and an address electrode that are sufficiently distant apart from each other in such a manner that a positive bias voltage can be applied to an address electrode during a reset period. In addition, it is possible to improve the luminance of a PDP and the quality of display of images by preventing a misdischarge such as a spot. Moreover, it is possible to prevent a panel driving circuit from malfunctioning and to improve the reliability of a panel driving circuit by applying a positive bias voltage to a plurality of address electrodes at at least two different times so that noise in driving signals can be reduced.

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly, to a method of efficiently driving a plasma display panel (PDP) and a plasma display device employing the method. Background technique [0002] A plasma display panel (PDP) is a display device that induces gas discharge by applying a predetermined voltage to a plurality of electrodes installed in a discharge space, and then excites phosphors by means of plasma generated due to the gas discharge. Display the image. PDPs are easily manufactured as large-sized thin flat panel displays. In addition, the PDP can provide high luminance and high light emission efficiency compared with other flat panel displays. [0003] Meanwhile, the PDP is driven in a time-division manner by using a reset period for initializing all discharge cells, an address period for selecting a plurality of discharge cells, and a sustain period for enabling selected discharge cells to cause a sustain dis...
