Improved PDP sustainers for reducing current stress and non-linear effect

Abstract

This paper presents three improved plasma display panel (PDP) sustainers for reducing current stress and nonlinear effect due to parasitic and distributed components. In the paper, a useful cell equivalent circuit model is first introduced to describe the behavior of PDP cell operation, and a widely used sustainer is then reviewed, on which three improved ones are proposed. The proposed sustainers can reduce currents through the switches and nonlinear effect due to parasitic and distributed components along the energy-recovery circuit paths. Derivation and operating principle of the proposed sustainers are addressed in detail. In addition, their related gaseous discharge mechanism in PDP cells is also presented. Hardware measurements have verified the feasibility of the proposed sustainers. © 2004 IEEE.
