Abstract

A driving circuit used on groove type of plasma display plate consists of voltage control circuit, pulse generator of positive-voltage maintaining voltage, maintaining circuit of positive-voltage energy recovery, pulse generator of negative-voltage maintaining voltage, maintaining circuit of negative-voltage energy recovery and PDP high-voltage driving IC chip with its output being connected to groove type of plasma display plate.

Description

technical field [0001] The invention relates to an image display driving circuit applied to a slot-type plasma display panel (SMPDP), especially a circuit for a brand-new slot-type plasma display panel (SMPDP) designed by reducing the withstand voltage requirement of a MOS switch tube. The driving circuit is specifically a driving circuit for a slot-type plasma display panel. Background technique [0002] The plasma flat panel display (PDP), which emerged in the early 1990s, has attracted widespread attention for its advantages of digitization, large screen, high resolution, high definition, wide viewing angle, thin thickness and light weight. [0003] At present, the existing PDP screens all use a three-electrode AC plasma flat panel display (AC-PDP). Sustain electrodes (X electrodes) and scan electrodes (Y electrodes), both of which are called display electrodes, address electrodes (A electrodes) are vertically distributed on the rear substrate, and X electrodes and Y ele...
