Energy recovery circuit for a plasma display

摘要

An energy recovery circuit (420,220) for a plasma display is disclosed. In one aspect, the display includes a scan driving board (210,220) that applies a sustain pulse to a scan electrode during a sustain period and a sustain driving board (400) that applies a sustain pulse to a sustain electrode during the sustain period. The scan driving board and the sustain driving board are connected by a harness (24). Ground wires are disposed at both sides of the harness and main path wires are disposed between the ground wires. The ground wires may be used to connect a ground terminal of a sustain transistor (Xg) and a ground terminal of the scan transistor (Yg) and/or the resonance capacitor (Cerc) to each other. The main path wires may be used to connect the sustain resonance transistor (Xr) to the transistor (Yf) connected to control the fall of the sustain pulse in the sustain pulse cycle.
