Radiated emission from plasma display panel (PDP) depending on addressing line structure and current driving scheme

Plasma Display Panel (PDP) is a significant source of EM noise due to 11s large panel size and enormous amount of . -driving current. In this paper, we investigated the eflec!. of the addressing 1ine.structure on the panel, .and the current . driving scheme on the radiated emission from the PDP. Firstly, we have demonstrated that the address operation is the main source of the radiated emission in a frequency range‘j?om 30MHz.to 200hHz. And we also showed that -the radiated emission from the dual addressing rype is .lower ihan that of the single addressing type by about IOdB.

43.1: A New 42-in. AC PDP Using MAoD II Driving Scheme

We present a new prototype 42″PDP using Samsung SDIs MAoD II driving scheme (Multiple Addressing with Overlapping Display period) suited for a high-resolution PDP. We used the commercial driver ICs to implement the entire parts of driving system and achieved the luminance of 600 cd/m2 with a single scan addressing method with the advantage of space charge priming. It also adopted 14 sub-fields in order to reduce the dynamic false contour.

Address‐While‐Display technique combined with gas‐discharge AND logic for driving AC‐PDPs

— A hybrid AWD/AND drive technique has been developed in which an Address-While-Display (AWD) scheme is combined with an AND logic characteristic that gas discharges demonstrate. The AWD technique enables AC-PDPs to be driven at high luminance, while the AND logic reduces the number of scan drivers by an order of magnitude. A detailed analysis of the addressing operation has been made. The hybrid drive utilizes the AND logic in two ways: (1) a combination of two voltage pulses and (2) a combination of a voltage pulse and discharge-priming particles. It was found that the addressing operation requires the establishment of a discharge between the scan and data electrodes, and also between the scan and display electrodes.
