  • We proposed the new reset waveform for reducing reset period. The square pulse is applied to the address electrode when the ramp pulse increases before a discharge occurs between sustain electrodes. If the discharge occurs between address electrode and X electrode, the wall charge is reversely accumulated between sustain electrodes compared with the applying voltage before the discharge occurs between sustain electrodes. So the next discharge more weakly occurs between sustain electrodes. If the more weak discharge is obtained, it can make the low background luminance and the high contrast ratio and reduce ramp up time in the ramp reset waveform.

  • In order to achieve high efficiency and low cost, new high-speed addressing method is suggested. This can be implemented by reducing the address discharge time lag through the priming effect. This paper suggests a new ADR(Address During Reset) driving method which provides priming particles by a separated driving method without adding auxiliary electrode or auxiliary discharge. The experimental results show an approximately 100ns reduction in the formative delay time of address discharge and a reduction in jitter of over 200ns. Also, due to enough time being available for reset, there was a reduction of about 29$\%$ in linht emitted during the reset period considerably.

  • This study is related to the realization of high speed address driving method for Full-HD PDP. The new self-priming addressing(SPA) driving scheme was proposed to improve an address discharge time lag, which utilizes the priming effect maintaining the priming discharge during an address period. In this study, the basic characteristics of the priming ramp discharge were investigated and optimize the reset pulse and priming pulse. It is noted that the address discharge time lag is significantly improved from 1.2[${\mu}s$] to 0.8[${\mu}s$] when the slope of the priming ramp pulse is below 0.1[$V/{\mu}s$].

  • As a driving method of AC-PDP, Address-Display Separated(ADS) driving has been widely adopted for its simple architecture and low discharge failure rate. However, a high definition like a HDTV has defect of long addressing time by reason of a number of pixels. Priming effect isn't fully sustained because of long addressing time during the address period. Therefore, it has different wall charge and luminance of each addressing time in the sustain period. In this study, we suggest a new driving waveform on the address period to improve these defects. We applied a ramp waveform, instead of a square waveform, to an address period in ADS, for operating on the AC-PDP, which used the conventional gas [He-Ne-Xe]. When the ramp waveform is applied to the address period, we experimented for uniform wall charge and the improved luminance by sustained Priming effect at each addressing time in the sustain period.

  • 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.

  • A new driving method is proposed to reduce the address period. The scan time of new driving method overlaps with the next scan time during the discharge lag time. Thus, without reducing the address pulse width and the scan pulse width, the new addressing method can reduce the address period. The results show that the scan time of about 100ns ${\sim}$ 300ns can be overlapped without the misfiring,.

  • The relationship between driving voltage and the amount of wall charge in the address period of surface discharge type AC Plasma Display Panel has been investigated. The amount of wall charge on each electrode is obtained simultaneously from the current profiles after applying only one addressing discharge pulse. The wall charge $Q_y$ on the scan electrode Y is almost the sum of $Q_x$ on the address electrode X and $Q_z$ on the sustain electrode Z. The $Q_y$ increased with the driving voltage regardless of the kind of electrode, whereas the addressing $T_d$ decreased. The $Q_x$ and $Q_y$ are increased considerably by blocking voltage $V_z$, whereas $Q_x$ is decreased. The $V_z$ dependence of $Q_x$ $Q_y$ and ${\varrho}_z$ in addressing discharge was $-13{\times}10^{-2}$ (pc/$V_z$), and $60{\times}10^{-2}$ ($pc/V_z$) and $70{\times}10^{-2}(pc/V_z)$, respectively.

  • An address voltage stabilization circuit for the single-side driving (SSD) method for AC plasma display panels (PDP) is proposed. The single-side driving method, which eliminates a common sustaining driver, uses only two electrodes in a three electrode AC PDP structure. The high-impedance (Hi-Z) mode operation of the data drive ICs during the sustaining period is needed for surface gas-discharge without misfiring in the SSD method but it produces the problem that the address voltage increases up to the breakdown voltage. The proposed circuit based on a flyback converter can stabilize the address voltage under the breakdown voltage and provide better surface gas-discharge performance without any misfiring in the SSD scheme.

  • To improve the luminance and efficiency of AC PDP, the effects of a square pulse applied to the address electrode during a sustain-period is investigated. Through this experiment, we confirmed the improvement of luminance and efficiency. We performed the temporal behavior measurement for the light emitted from AC PDP at floating state of the address electrode and at various auxiliary voltages (including ground state) applied to the address electrode using the scanned point detecting system. In the case of using an auxiliary voltage pulse, emission starts at the inner edges of the anode and cathode simultaneously. Also, we obtained the larger two discharge volumes compared with the normal sustain discharge where address electrode is floated.

  • The relationships between driving voltage and the wall charge distribution in the address period of surface discharge type AC Plasma Display Panel have been investigated. The quantity of wall charge on each electrode are detected simultaneously from the electrode current after applying only one addressing discharge pulse. The wall charge Qy on the scan electrode Y is nearly the sum of Qx on the address electrode X and Qz on the sustain electrode 2. The Qy increased with the driving voltage regardless of the kind of electrode, whereas the address time Td decreased, Qz and Qy are increased considerably with the blocking voltage Vz, whereas Qx is decreased. The increase rate of Qx, Qy and Qz for increase in Vz was $-13{\times}10^{-2}$(pc/Vz), and $60{\times}10^{-2}$(pc/Vz) and $70{\times}10^{-2}$(pc/Vz), respectively.
