Therefore, there is a disadvantage in that after any sustain discharge, the recombination of the space charges 401 and the wall charges 400 causes a decrease in the amount of the wall charges 400 participating in the sustain discharge, thereby causing a high temperature misdischarge that does not generate the next sustain discharge.

[0227] Like the seventh embodiment, in the driving method of the eighth embodiment of the present invention, only the application time point of the scan pulse applied to the scan electrode in the address period and the data applied to the address electrode are shown and described. The case where the application time points of the pulses are different from each other. However, the eighth embodiment of the present invention is the same as the sixth or second embodiment, and therefore, even in the eighth embodiment of the present invention, like in the sixth or second embodiment, the length of the sustain period is controlled to The number of space charges in the discharge cells is reduced. The length control of the sustain period of the eighth embodiment of the present invention is basically the same as that of the sixth or seventh embodiment, and therefore, description thereof is omitted. In addition, description of the drawings will be omitted.

Abstract

Provided are a plasma display device and a driving method thereof. The plasma display device includes a plasma display panel having scan electrodes, sustain electrodes and address electrodes; a first controller for controlling the application time points of data pulses for the address electrodes during the address period to be different from those for the an application time point of a scan pulse of the scan electrode; and a second controller for controlling a last sustain pulse applied to at least one of the scan electrode and the sustain electrode, wherein the second controller is controlled when the temperature in the plasma display panel or When the temperature around the plasma display panel is substantially room temperature, the interval between the application time point of the last sustain pulse and the initialization signal of the next subfield is controlled to be longer than the interval of the PDP at room temperature.

Description

technical field [0001] The present invention relates to a plasma display device, and more specifically, to a plasma display device and a driving method thereof, which are used for preventing wrong discharge, fault discharge and abnormal discharge, increasing the contrast ratio of a dark room, for increasing working margin, and for The application time points of the pulses applied in the address period and the sustain period are embodied differently. Background technique [0002] In an existing plasma display panel, a space between barrier ribs formed between a front panel and a rear panel provides a unit cell. Each cell is filled with a main discharge gas such as neon (Ne), helium (He) or a mixed gas of neon and helium (Ne+He), and an inert gas including a small amount of xenon (Xe). A plurality of these units form a pixel. When a discharge occurs using a high-frequency voltage, the inert gas generates vacuum ultraviolet rays and irradiates the fluorescent material dispose...
