Abstract
In a PDP driving method, an image of each field displayed on the PDP corresponding to an input video signal is divided into sub-fields with different weights, and a combination of the weights is used for gradation. The method includes: determining an automatic power control (APC) level for driving the PDP; determining a pulse width comprising any one of an address pulse width, a sustain pulse width, and a reset pulse width, or a combination of at least two of the three pulse widths for each sub-field using the APC level, the determined pulse width including as an increment a part of a pause period occurring in driving the PDP at the APC level; and performing addressing on the PDP according to the pulse width.
