Abstract
A separate voltage driving apparatus for a plasma display panel that is capable of restraining an abnormal brightness caused by a characteristic deviation of the panel as well as preventing a damage of switching devices caused by an overcurrent. Any one of sustaining drivers of the apparatus can include a writing voltage generator, a sustaining voltage generator that generates pulses, each of which has a voltage level and a pulse width required for sustaining the writing discharge of the entire cells between the first and second electrodes, having a phase contrary to and being synchronized with each other, and an erasure scanning voltage generator. A voltage driving apparatus can further include a voltage recovering stage and a voltage input/output stage.
