The plasma display apparatus includes a first electrode and a second electrode formed on an upper substrate, and a barrier rib. The second electrode is arranged in parallel with the first electrode. The barrier rib is formed on a lower substrate opposite to the upper substrate to divide a discharge space. The first electrode and the second electrode are respectively protruded toward the discharge space to have a predetermined thickness. A discharge occurs between the first electrode and the second electrodes opposite to the first electrode. Since the margin of static characteristics increases, the voltage range in which stable driving is possible increase and the amount of the consumption of the discharge current decreases, to thereby reducing power consumption, and enhancing the luminous efficiency and the efficiency of the plasma discharge.

Plasma display panel(apparatus)

An apparatus and method for driving a plasma display panel wherein an initializing discharge can be weakened to lower a dark room brightness and an initialization time can be shortened to permit a single scanning. In the apparatus, a sensing device senses an electrical signal with an initialization waveform applied from a voltage source to a display panel. A controlling device controls said electrical signal with an initialization waveform applied from the voltage source to the display panel by the sensed electrical signal.

Apparatus and method for driving plasma display panel

A plasma display panel driving method that is adaptive for improving contrast. In the method, at least one of the first and second electrodes keeps a floating state in an initialization period of at least one sub-field of a plurality of sub-fields.

Plasma display panel and driving method thereof

An electrode for a plasma display panel (PDP) in which an electrode having a high adhesive power is formed on a glass substrate of a color plasma display panel and a method for forming the same. The electrode for the PDP includes a metal ceramic thin film formed between a metal electrode and a dielectric substrate. The method includes steps of forming a metal ceramic thin film on a predetermined portion of the dielectric substrate and forming an electrode having the same metal element as the metal ceramic thin film on the metal ceramic thin film.
