“…Slottow and Petty showed that the slope of the voltage transfer curve around the operating point must be less than 2 for stable operations (see the example of figure 9). Weber et al [40,41] defined a slightly different wall voltage inputoutput curve that plots the output wall voltage as a function of input wall voltage. These curves can be used, for example, to determine the optimal values of the writing, sustaining and erasing voltage pulses of figure 3, or to analyse how the two stable states of the cell, the ON or OFF states respond to a perturbation.…”

In this paper, we describe the principles of operation of a plasma display panel (PDP) and the physical mechanisms controlling the performances of a PDP in terms of light emission efficiency, lifetime and image quality. Emphasis is put on the physics of the plasma occurring in a PDP cell, on the discharge optimization, and on the analysis of recent results provided by experimental and numerical diagnostic tools. We focus on alternative current PDPs, where the plasma is generated by a dielectric barrier discharge, the configuration adopted by most PDP companies. The recent improvements and the remaining research issues are discussed.

“…In the barrier discharge, a dielectric surface acts as an electrode and the wall voltage due to charges determines a basic structure of discharge such as a pulsed operation. The wall voltage has been calculated from computer simulations [1,2] and indirectly estimated from experiments on a circuit analysis [3][4][5] and from LIF spectroscopy [6,7].…”

The wall voltage in a barrier discharge has been directly measured using an electro-optic crystal, KDP. One of the barriers is made up of a plate of KDP. A wall voltage due to charges accumulated on KDP surface is measured at various discharge conditions from the change of polarization of a laser transmitting through KDP. The value of the wall voltage at applied voltage of 1 kV and Ar gas pressure of 3 Torr is about 120 V. This indicates that the accumulated charge is about 1.1 nC.

“…However, the electrical characterization and, in particular, device modeling for ac-PDP is still far from being able to explain and predict the cell operations quantitatively. Until now, the PDP cell characterization efforts have been limited to the 2-electrodes cell structure with square wave excitation pulses [2,3]. Although the gas discharge behavior characterized from those methods led to the better understanding of the basic cell operations of write, sustain and erase, it still falls short in explaining quantitatively how the physical state of an ac-PDP cell affected by various external stimulations particularly when the third electrode is involved as addressing means.…”

A new concept for analysis of operational characteristic of ac-PDP is proposed in this paper. The physical state of ac-PDP cell is defined in terms of wall voltages, which can be traced through the various stages of PDP driving sequence. The voltage domain analysis in combination with firing voltage measurement identifies the cell state and allows the estimation of wall voltage difference between two different cell states. Firing voltage measurement also presented invaluable information on the gas discharge characteristics of ac-PDP. IntroductionRecently, the plasma panel display technology has become mature enough to enable the industry to manufacture very large screen size display over 60" with the resolution and image quality comparable to the CRT[1]. All these achievements have been possible with the technological advances in fabricating process and driving method for surface-discharge type ac-PDP. However, the electrical characterization and, in particular, device modeling for ac-PDP is still far from being able to explain and predict the cell operations quantitatively. Until now, the PDP cell characterization efforts have been limited to the 2-electrodes cell structure with square wave excitation pulses[2,3]. Although the gas discharge behavior characterized from those methods led to the better understanding of the basic cell operations of write, sustain and erase, it still falls short in explaining quantitatively how the physical state of an ac-PDP cell affected by various external stimulations particularly when the third electrode is involved as addressing means. As the recent development in ac-PDP driving method tends to adopt more sophisticated voltage wave forms to set up the initial condition of panel before the display operations begin, it cannot be overstated how much important to understand what kinds of discharge mode exist and how they are triggered and change the physical state of a cell afterward. The voltage domain analysis proposed in this paper defines the physical state of PDP cell using the gap voltages within the voltage domain bounded by firing voltage and provides the information how the cell will behave with certain external applied voltage in addition to the wall voltages formed from previous operations. The measurement results show there are two distinct gas discharge modes, XY and AY(or AX) in firing voltage characteristics of 3-electrode ac-PDP cell. The experiments also revealed that the shape of firing voltage contour undergoes slight changes from operation to operation due to the non-uniform distribution of wall charge even though the firing voltages of two discharge modes remain constant as long as the priming effect is not in extreme level. The concept of voltage domain analysis is explained in section II. And in section III, the experimental procedure and results of firing voltage measurement are discussed followed by the conclusion of section IV. Voltage Domain AnalysisThe structure of ac-PDP cell and its lumped-model equivalent circuit are shown in Fig. 1, where C D is the ...
