ABSTRACT:
It is an object of the present invention to provide a plasma display apparatus in which reliable erase discharge is performed and an erroneous discharge is suppressed, even when a discharge sustain period is shortened so as to realize a PDP having high definition.The above object is achieved in the following manner. In the discharge sustain period, a pulse applied in the later part of the discharge sustain period has a larger pulse width than a pulse applied in the earlier part of the discharge period, except for an initial pulse in the discharge sustain period. In addition, a called narrow pulse is applied in an erase period to perform an erase discharge. According to this method, wall voltages in discharge cells at the end of the discharge sustain period are raised to a higher level than in the related art. As a result, reliable erase discharge is performed, and an erroneous discharge is suppressed.
