Abstract

The invention relates to a energy recovery device for plasma display board, which comprises capacitor load equivalent formed between scanning and maintain electrodes, a energy recovery unit to recovery and provide energy charged in capacitor to capacitor again, a energy supply unit between recovery unit and capacitor to relay energy from capacitor and energy recovery unit, provide reference voltage to capacitor load and generate stable discharge in capacitor, and an energy relay unit arranged between energy recovery and supply units to relay energy between said units. This invention needs no diode to decrease cost.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly to an energy recovery device and method for a plasma display panel. Background technique [0002] The plasma display panel (hereinafter referred to as "PDP") is suitable for displaying symbols or graphics by emitting ultraviolet light with a wavelength of 147nm generated during the discharge of an inert gas mixture such as He+Xe, Ne+Xe or He+Ne+Xe. Image. Such a PDP is easy to be made large and thin, and can provide significantly improved image quality with the recent development of related technologies. Specifically, the three-electrode AC surface discharge type PDP has the advantages of low driving voltage and long product life since wall charges accumulate on the surface during discharge and electrodes are prevented from being sputtered by discharge.
