In this paper, we used the V-Q Lissajous‘ figure for studying on the plasma discharge characteristics of the 42 inches AC-PDP. From the V-Q Lissajous‘ figure, we could observe exactly the driving conditions that the self-erasing discharge takes place. At the time, the total wall charges lessened by self-erasing discharge was calculated quantitatively. Beside of the just observation of self-erasing discharge and calculation of the charges lessened, we could find out the optimum driving conditions for inducing the maximum wall charges accumulated on the dielectric layer with measuring the Wall voltage from the V-Q Lissajous' figure.

To understand the discharge characteristics in AC-PDP, it is necessary to study on the wall charge behavior. But, it is difficult to measure the wall charge directly. In this paper, the V-Q Lissajous' figure is used to measure the wall charge indirectly and analyze the wall charge behavior. With the V-Q Lissajous' figure, the discharge characteristics of AC-PDP are studied according to vary driving conditions, such as the frequency, pulse duty ratio, and rising & falling time. As a result, the V-Q Lissajous' figure is used to measure the discharge characteristics of the AC-PDP. It is confirmed that firing initial voltage and firing final voltage for discharge are effected by the aboved variables. Related with the wall voltage generation, it is thought that the difference of the slope at the V-Q Lissajous' figure is caused by charged ions inside the dielectric layer.

In this paper, we apply V-Q Lissajoucs' figure for observation of a V-Q (Voltage-Charge) hysteresis loop at interface between phosphor and insulation layer in P-ELDz which are a simple structure and the back lighting of LCDs (Liquid Crystal Display). In V-Q Lissajous' figure, we measured a change of hysteresis loop according to the thickness of Insulation and phosphor layer. From experiment result, we will be obtained a optimum thickness of insulation with comparing the correlation of a V-L (Voltage-Luminance) and V-Q hysteresis loop.

The characteristics of Xe discharge lamp(Mercuryless lamp) are described in this paper. In this paper, FFL is operated by sine wave and pulsed source. We apply V-Q Lissajous' figure for the discharge measurements of FFL which has the electrodes covered with dielectric. When FFL is operated by sine wave source, the characteristics are similar to DBD(Dielectric Barrier Discharge) and SD(Silent Discharge). And we compared the characteristics of FFL which is operated with sine wave and pulsed discharge by using V-Q Lissajous' figure method. When FFL is operated with pulsed, the discharge current flows after the applied voltage is risen. As the duty ratio increases the electric field becomes strong and much more xenon ions are produced. And the number of metastable xenon atoms seem to increase, therefore, the phosphor radiation after the cut off of voltage increases compared with the first peak of radiation. Consequently, the 172㎚ radiation becomes strong as the duty ratio increases.

This experiment was analysed the discharge characteristics of FFL(flat fluorescent lamp). FFL is operated by sine and pulse wave source. We use FFL which has the electrodes covered with dielectric, observed the discharge characteristics of FFL by V-Q Lissajous' figure. When FFL is operated with pulsed, the discharge current flows after the applied voltage is risen. When the duty ratio increases, the number of metastable xenon atoms seem to increase. Consequently, the 172nm radiation becomes strong as the duty ratio increases.
