AI Technical Summary

Problems solved by technology

First, it has a very complex structure since it has many switching elements
Second, it is expensive to produce due to the use of high-cost MOSFET switches as switching elements
Third, the switching element does not perform ideal zero-voltage switching due to unwanted parasitic parts such as the parasitic resistance and capacitance of the inductor, the parasitic resistance of the panel, the on-resistance of the switching element, etc.
Fourth, since the capacitor Cc has not been charged to Vs / 2 volts and starts to keep discharging, a very large abnormal current is generated

Embodiment Construction

[0030] Preferred embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings, an example of which is shown.

[0031] attached image 3 Shown is a circuit diagram of an energy recovery holding circuit for an AC plasma display panel according to a preferred embodiment of the present invention. as attached image 3 As shown, the energy recovery holding circuit includes first to fourth switching elements S1, S2, S3 and S4 connected to the load capacitor Cp (ie, the plasma display panel) in the form of a bridge. The four switching elements S1, S2, S3 and S4 respectively include body diodes d1, d2, d3 and d4 connected in parallel thereto. Both the second and fourth switching elements S2 and S4 are grounded. The fifth switching element Sa includes one end connected to the first and third switching elements S1 and S3 and the other end connected to the positive terminal of the Vs voltage and the first capacitor C1. One en...

Abstract

The present invention discloses an energy recovery sustain circuit for an AC plasma display panel in which includes one energy recovery sustain circuit incorporating X and Y electrodes.

Description

[0001] This application claims the benefit of Korean Patent Application No. 2000-56355 filed September 26, 2000 under 35 U.S.C. §119, which is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to a plasma display panel (PDP), in particular to an energy recovery and holding circuit of an AC plasma display panel. Background technique [0003] An AC plasma display panel is a light-emitting device that displays images by applying gas discharge in each discharge cell. Because the AC plasma display panel is simple to manufacture, easy to manufacture a larger-sized display screen, and has a fast response, it is used as a direct-view image display with a large screen, especially as a display in the HDTV (High Definition Television) era. attention. [0004] An AC plasma display panel has electrodes, a dielectric layer, and a discharge gas, which itself acts as a load capacitor for charging and discharging. However, the large po...
