  • The display module of PDP consists of a pair of fine electrode patterned panels. For example, in case of 42" PDP, thousands of electrode patterns should be placed on panel, where length, width, and height of each pattern m one meter, 50${\mu}{\textrm}{m}$, and 30${\mu}{\textrm}{m}$ respectively. And pitch between patterns is around 200${\mu}{\textrm}{m}$. Electrode patterns are frequently damaged during the production process, and thus might be broken. These breakage will result in open-circuited electrical characteristic of a pattern and/or open-circuited electrical characteristic between patterns. Therefore, inspection of pattern defects is the inevitable process to improve production yield rate of the panel. In this paper, we first review several types of PDP pattern defects which affects yield-rate of PDP. And, problems of inspecting such pattern defects by a typical inspection method is addressed. Then, a novel inspection method is proposed to overcome the difficulties, where some new components and the algorithm to detect the electrode defects are explored.ored.

  • In this work we compared different sources of composition of Ag powders obtained by dry and wet process on the photolithographic patterning of PDP electrode and resistance of sintered Ag electrode. It was found that 90 : 10 wt% ratio of Ag powder made by dry and wet processes gave optimum result both on the PDP electrode pattern and resistance of PDP electrode after sintering.

  • The newly designed Ac-PDP(plasma display panel with comb-type electrode) structure was fabricated by using the screen printing method and the electrical and optical characteristics were measured under the various discharge conditions. The minimum firing voltages measured under pure Ne and Ne+Xe mixture gas with the application of 10 kHz square wave were 190V and 160V, respectively. The firing voltages of the PDP cell with the comb-type electrode were compared with those of the cell with matrix electrode under the same discharge condition. The firing voltage of the PDP cell with comb-type electrode was 15 V lower than that of the PDP cell with conventional matrix electrodes.

  • In the recent years, much interests and attraction has been paid on the plasma display panel. To achieve high performance display panel, there has been a strong demands for studies on the transparent conducting films such as ITO and ZnO. In this study, we propose PDP cell with ZnO transparent conducting electrode. The electrical and optical characteristics of PDP cell with ZnO transparent electrode were studied and compared with that of conventional ITO electrode.

  • In a conventional plasma display, the bus electrode was located on the ITO electrode at the outer part of each cell. We propose a new electrode configuration using vertical auxiliary electrodes which play a role of electrically connecting ITO and bus electrodes with the aim of enhancing discharge and luminous characteristics of the PDP (Plasma Display Panel). In this paper, luminance and luminous efficiency of the 3 in.-diagonal test panel are measured with various number of vertical auxiliary electrodes such as 2, 50 and 150. The change in the luminous characteristics is explained in connection with the discharge characteristics of the PDP cells such as current peak, IR emission peak and ICCD picture image.

  • In this paper, we propose IBS(ITO-BUS Separated) electrode structure. BUS electrode lines are placed apart from the ITO electrode lines, and they are electrically connected with vertical auxiliary electrodes. We varied the lengths of the vertical electrodes as 70, 120, 320um. The highest luminous efficiency and the largest IR emission peak were obtained for 70um length.

  • The gas discharge AND gate which have been newly proposed is applied to three electrode surface discharge AC PDP. The address discharge characteristics by the DC-AC floating discharge by which Y electrode is made floating electrode is analyzed The address discharge can be begun by using the floating discharge from the experiment result Moreover, the display discharge can be sustained. The DC priming discharge that the floating discharge is matched to timing is generated in a supplementary electrode. As a result, space charge is supplied enough to the space of the floating discharge and the data voltage is lowered up to l00(V). Driving method to use this DC-AC floating discharge is able to obtain the address operation margin of l00(V).

  • A nonthermal bioplasma source was developed for application to human liquid fluids by making use of nano-size tungsten tips. Characteristics of the plasma source are investigated. Here we have used the AC voltage system. The bioplasma source generated by a tungsten tip with quartz tube and ground electrode is a low-temperature plasma without making any noticeable damage to cells at a low power operation. The breakdown voltage and current signals are measured by high voltage probe (Tektronix P6015A) and current probe (P6021). Variation of breakdown temperature near the tip electrode is larger than that in the neighborhood of ground electrode. Bubble formation during discharge has been recorded and investigated by using the high speed camera. The existence and behavior of hydroxyl and superoxide radicals are detected and measured by spectrometers. The electrical and optical properties of breakdown characteristics are also investigated.
