Abstract

A PDP(Plasma Display Panel) module consists of a discharge panel, a SMPS(Switched Mode Power Supply) for power supply, driving boards for panel control, and a logic board. Driving boards supply high voltage pulses to induce glow discharge in the PDP panel. The electrical pulses excite the circuit elements and subsequently generate acoustic noises. The main sources of the noise in the circuit are the transformer of SMPS and the power MOSFET(Metal Oxide Semiconductor Field Effect Transistor) of driving boards, and the heat sinks often amplify the noise level. The reduction of the acoustic noises was achieved by modifying both the structural and circuit elements. The structural method was executed by the improvement of heat sinks. The optimization of SMPS and condensers was carried out for the circuit elements.
