Abstract

A plasma display device and a driving method thereof are provided to prevent a high-temperature error in discharge by varying a scan voltage applied to a scan electrode, according to temperature. A plasma display device includes a scan driver(120) having plural switches(S1~S5). The switches apply scan pulses on respective scan electrodes(Y1~Y5). When an address period begins, a scan pulse is sequentially applied on the scan electrodes irrespective of an image signal. The first scan switch is turned on and a negative voltage is applied on the first scan electrode, so that the scan pulse is applied on the first scan electrode. The rest scan switches are sequentially turned on, so that the scan pulses are applied on the scan electrodes. At the application timing of the scan pulse, a positive data pulse is applied on an address electrode, so that an address discharge is generated between scan and address electrodes. The address electrode is formed to cross the scan electrode.

Description

technical field

[0001] The present invention is an invention related to a plasma display device and a driving method thereof, and particularly an invention related to a plasma display device and a driving method thereof capable of preventing high-temperature misdischarge by changing an applied scanning electrode according to temperature. Background technique

[0002] The plasma display panel is a display device that discharges the gas inside the substrate, and the generated vacuum ultraviolet rays (VUV) collide with phosphors inside the substrate to generate light. As shown in Fig. 1, a plasma display panel is largely composed of a front substrate (A) and a rear substrate (B).

[0003] The front substrate (A) is composed of scan electrodes (1) and sustain electrodes (2) formed in sequence, and a dielectric protection layer (4) laminated on the scan electrodes and sustain electrodes.

[0004] The scan electrodes (1) and the sustain electrodes (2) respectively have a relative...
