Embodiment Construction

[0034] Preferred embodiments of the present invention are explained in more detail with reference to the accompanying drawings.

[0035] A plasma display according to the present invention includes: a plasma display panel including a scan electrode and a support electrode; a scan driver for applying a negative voltage to the scan electrode before a reset period when the scan electrode is applied with a positive voltage; and a support driver for A positive voltage is applied to the support electrode when the scan electrode is applied with a negative voltage.

[0036] The minimum value of the negative voltage applied to the scan electrodes is equal to the minimum value of the scan pulse voltage applied in the address period.

[0037] The absolute value of the negative voltage is greater than the absolute value of the positive voltage applied to the supporting electrode.

[0038] The magnitude of the positive voltage applied to the support electrode is greater than 150V and less...

Abstract

The present invention relates to plasma displays. A plasma display according to the present invention includes: a plasma display panel including a scan electrode and a support electrode; a scan driver for applying a negative voltage to the scan electrode before a reset period when the scan electrode is applied with a positive voltage; and a support driver for A positive voltage is applied to the support electrode when the scan electrode is applied with a negative voltage.

Description

technical field [0001] The present invention relates to plasma displays. Background technique [0002] Generally, in a plasma display panel, a barrier rib formed between a front substrate and a rear substrate forms a unit cell. Each cell is filled with a main discharge gas such as neon (Ne), helium (He), or a mixed gas of Ne and He (Ne+He), and an inert gas including a small amount of xenon. If an inert gas is discharged with a high-frequency voltage, vacuum ultraviolet rays are generated. Phosphors formed between the partition walls emit light to display images. Such a plasma display panel can be made light and thin, and thus has come into the center of attention as a next-generation display device. [0003] figure 1 The construction of a general plasma display panel is shown. [0004] like figure 1 As shown, the plasma display panel includes a front substrate 100 and a rear substrate 110 . The front substrate 100 has a plurality of support electrode pairs arranged o...
