Plasma display device

Abstract

This invention discloses a plasma display device including multiple capacitors charged by current recovered by panels in maintenance regions, a current path switch part with the current flowing to the panel formed by the connection of said multiple capacitors and a sensing part forming resonant current between the switch part and the panel. This invention uses multiple capacitors to provide and recover energy to increase the drive effect of energy recovery circuit.

Description

1. Technical field [0001] The present invention relates to a plasma display device, and more specifically, to a plasma display device that uses a plurality of capacitors to form a recovery unit, performs energy supply and recovery with a plurality of energy recovery voltages, and forms sustain pulses. 2. Background technology [0002] A plasma display panel is a representative device in which vacuum ultraviolet rays (VUV) generated by gas discharge inside the panel collide with phosphors inside the panel to emit light. As shown in FIG. 1 , the plasma display panel generally consists of a front glass plate A and a rear glass plate B. As shown in FIG. [0003] The front glass plate A is sequentially composed of scan electrodes 1 and sustain electrodes 2 , a dielectric layer 3 superimposed on the scan electrodes and sustain electrodes, and a dielectric protection film 4 formed on the dielectric layer. [0004] The driving signal for driving the plasma display panel is provided...

AI Technical Summary

Problems solved by technology

[0031] However, the ER voltage generated by actual resonance cannot be raised or lowered to a high-potential sustain voltage or a low-potential sustain voltage

This is because of the parasitic impedance in the circuit and the leakage power consumption of various circuits
