  • We measured 3-dimensional temporal behavior of the light emitted from AC plasma display panel(PDP) at various auxiliary voltage pulse width supplied to the address electrode in sustain period using scanned point detecting system. In the case of applying an auxiliary address voltage pulse, the light emission starts at the inner edges of the cathode so the larger discharge volume toward address electrode can be obtained compared with the normal sustain discharge. Especially, when the auxiliary voltage pulse width is the $2{\mu}s$, the maximum luminance and long emission time can be obtained.

  • X-ray lithography was employed to fabricate ITO-less high resolution sustain electrodes for plasma display panel (PDP). A polyimide film based X-ray mask and Xray sensitive Ag electrode paste were fabricated to check their effect on the patterning of Ag electrodes with less than 30 ${\mu}m$ in width. The X-ray lithographic method was found to be useful for the high resolution sustain electrode patterns due to the high penetration power and low scattering property of X-ray source.

  • We investigated the effect of sustain electrode gap variation with high Xe content in an ac Plasma Display Panel through two-dimensional numerical simulation to understand the inherent high luminous efficiency mechanism. For the low Xe content, the optimal sustain electrode gap turned out to be about 200 ${\mu}m$, but with higher Xe content, the VUV generation efficiency increased as the electrode gap increases beyond 200 ${\mu}m$. We found that it is due to higher electron heating efficiency in the cathode sheath under the condition of long electrode gap and high Xe content.

  • The discharge characteristics of AC plasma display were investigated as a function of the voltage and the frequency of the pulses applied to the address electrode during sustain period. The maximum sustain voltage of display cell decreased with increasing the frequency of the pulses applied to the address electrode during sustain period. Applying the pulses to the address electrode resulted in improvement of luminance and luminous efficiency at the same time.

  • To improve the luminance and luminous efficiency of a surface-discharge alternate current plasma display panel, we analyzed the sustain discharge characteristics as the voltage of the address electrode In the study. As the results, when the address voltage is a half of the sustain voltage in the sustain period, the luminance and luminance efficiency are the highest. The luminance efficiency increased about 16.2%~20.8% compared with the conventional type.

  • We propose new driving schemes, asymmetry and long gap mode, of PDP having auxiliary electrode between scan and common electrode. For the asymmetric modes, the auxiliary electrode located nearly center of the primary electrodes is connected to the scan of common electrode during all periods of reset, address and sustain. For the long gap mode, it is electrically disconnected or maintained at dc voltage of Vs/2 during sustain period except the first several sustain pulses. The proposed structure and driving method can provide higher luminous efficacy by minimizing consumption energy. The effectiveness of the new driving schemes has been investigated for various Xe partial pressure conditions.

  • The temporal dark image sticking phenomena are examined and compared for the two different electrode structures such as the face-to-face and coplanar sustain electrode structure. To compare the temporal dark image sticking phenomena for both structures, the differences in the infrared emission profile, luminance, and perceived luminance of the image sticking cells and the non image sticking cells were measured. It is observed that the temporal dark image sticking is mitigated for the face-to-face structure. The mitigation of the temporal dark image sticking for the face-to-face structure is due to the slight increase in the panel temperature induced by the ITO-less electrode structure.

  • The discharge characteristics of the face-to-face sustain electrode structure employing auxiliary address pulse are investigated under a sustain driving frequency of 20 kHz and various auxiliary address pulse widths (500 ns, $1{\mu}s$, $2\;{\mu}s$) in the 6-in. test panel (42-in. Full HD grade) with a pressure of 450 Torr and a 4 % Xe-content. The luminance and the luminous efficiency at the auxiliary address pulse width of 500 ns are improved more than these of $1\;{\mu}s$ and $2\;{\mu}s$. At the auxiliary address pulse width of 500 ns, the luminous efficiency shows about 0.96 lm/W at the auxiliary pulse of 90 V and the sustain voltage of 260 V.

  • A new sustain driving method is proposed to improve luminous efficiency by the generation of the self-erasing discharge during a sustain period in AC plasma display panel. As one subfield time in the conventional AC PDP is divided into the reset, address, and sustain period. Among them, as the square sustain waveform is alternately applied to the X and Y electrodes on the front plate during the sustain period, the plasma discharge for displaying the image is continuously produced. Meanwhile, in the conventional driving method, the address waveform applied to the A electrode on the rear plate is only driving during an address period and grounded during a sustain period. In this experiment, the negative pulse is applied to the A electrode at the latter part of the sustain pulse for improving the luminous efficiency producing the self-erasing discharge during the sustain period. The negative pulse on the A electrode can change from the space to the wall charge and induce the additional discharge by the accumulated wall charge when the voltages of three electrodes are grounded. As a result, the luminous efficiency will be measured with changes in the voltage level of the A electrode and the new driving method can be improved to the luminous efficiency about 32 % compared with the conventional driving method.

  • The relationships between discharge characteristics and sustain electrode shape are studied in AC PDP by calculating the electric field and measuring discharge voltage, luminance and current. The maximum electric field is obtained for the triangle shape electrode. It is 1.8 times larger than uniform electric field type. It has been shown thatthe firing voltage is largely affected by the degree of electric field concentration. But, as the difference of the maximum and minimum value of electric field in a cell increases, the luminance and luminance efficiency decrease. And, the charge variation during discharge is proportional to the area of electrode.
