A plasma display apparatus comprises a scan electrode and a sustain electrode; a data electrode for intersecting the scan electrode and the sustain electrode; and a pulse controller for controlling to apply a pulse having an opposite phase to the scan electrode and the sustain electrode during a reset period and apply a negative sustain pulse to the scan electrode and the sustain electrode during a sustain period, wherein a distance between the scan electrode and the sustain electrode is longer than that between the sustain electrode and the data electrode. Therefore, a surface discharge mode can be used even when applying negative pulses to the sustain electrode in a reset period, and a size and cost of a plasma display apparatus can be reduced by applying a negative pulse of the same magnitude as a sustain voltage without a separate negative voltage source.

Plasma display apparatus and driving method thereof

A plasma display panel is disclosed. More particularly, the present invention relates to a plasma display panel, which can improve discharge stability as well as brightness and efficiency. The plasma display panel according to the present invention includes transparent electrodes (ITO electrodes) spaced in parallel to each other at a predetermined distance; and metal electrodes each formed on the transparent electrodes (ITO electrodes) in parallel to the transparent electrodes (ITO electrodes) so that the respective transparent electrodes (ITO electrodes) are inclined toward the side where the transparent electrodes face.

Plasma display panel and method of driving the same

The present invention relates to a plasma display panel, and more particularly, to an electrode structure of a plasma display panel capable of improving brightness and efficiency. According to a first embodiment of the present invention, in a plasma display panel of a long column structure having a front substrate and a rear substrate that are opposite to each other, the transparent electrodes of the scan electrodes or the sustain electrodes include projections projected toward the center of the discharge cells every discharge cell. Also, a discharge start voltage and a discharge sustain voltage can be lowered and brightness and efficiency can be increased. It is also possible to maintain color temperature equilibrium every RGB cell and to reduce an erroneous discharge of each cell.

Plasma display panel

A PDP and a driving method thereof are disclosed in which luminous efficiency can be improved. The PDP includes: a pair of sustain electrodes formed at a peripheral portion of an upper substrate; and a trigger electrode formed at the center of the upper substrate.

Plasma display panel and driving method thereof

A PDP and a driving method thereof are disclosed in which luminous efficiency can be improved. The PDP includes a scan/sustain electrode formed at a peripheral portion of a discharge cell, a common sustain electrode formed to oppose the scan/sustain electrode at the peripheral portion of the discharge cell, a first trigger electrode formed to be adjacent to the scan/sustain electrode, and a second trigger electrode formed to be adjacent to the common sustain electrode.
