Plasma display apparatus

Abstract

Provided a plasma display apparatus. The apparatus includes a first electrode and a driver. The first electrode is formed at an upper substrate. The driver applies a sustain pulse to the first electrode. The driver applies a driving waveform whose, in one subfield, any one sustain pulse (SP1) has a longer falling time than another sustain pulse (SP2) applied earlier than the sustain pulse (SP1).

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly, to a plasma display device for prolonging the falling time of a sustain pulse applied at the end of a sustain period and partially erasing the excessively formed discharge cell. The internal wall charge, thereby preventing misdischarge. Background technique [0002] FIG. 1 illustrates driving waveforms for driving a conventional plasma display device, and FIG. 2 illustrates sustain pulses applied at the end of a sustain period in the conventional plasma display device. [0003] As shown in FIG. 1, the driving waveform includes: a reset period (R), an address period (A) and a sustain period (S). During the reset period, a setup reset signal (R-up) and a setup down reset signal (R-dn) are sequentially supplied. If the set-up reset signal (R-up) is supplied, a reset discharge is generated between the scan electrode (Y) and the sustain electrode (Z), and wall charges are sto...

Problems solved by technology

[0010] However, it is disadvantageous in that, although the fall time (Tf) of the last sustain pulse is set to about 600 ns, when the last sustain pulse (SP) is applied, excessively formed wall charges are not sufficiently erased from the discharge cell, and generation Misdischarge of luminescent spot
