A new high speed addressing method is proposed to reduce the addressing time below lus per line in AC PDP. In this method, the priming discharge is used to achieve a high speed addressing without adding an auxiliary electrode. Two different types of priming discharges were studied to achieve a high speed addressing and also reduce the inherent light output caused by the priming discharge in order to improve the contrast ratio characteristics. In the panel experiment, the addressing was successfully done with a lus address pulse width in the new method and the better contrast ratio was achieved in the Y-A priming rather than the Y-X priming case even though the reduction of the address period was smaller than that of the Y-X priming due to the extra address time for the priming discharges.

The conditions of the wall charges and priming particles in a unit discharge cell in AC PDP seriously affect the addressing discharge characteristics in the driving method with ramped setup pulse. Moreover, the discharge conditions at the end of the scan line may be different from the first scan line because of the difference of about 1ms address time. Consequently, the addressing time and its dispersion may be different for any two discharge cells that lead to misfiring and the increase in the total addressing time. In order to improve the addressing time and its dispersion, we have applied different addressing voltage at each cell such as progressively increase pulse voltage instead of constant one. As a result, the addressing time and its dispersion of all cells were improved by about 30% compared with the conventional driving method.

One of the most important problems in ADS method is that the method has too long addressing period, The addressing time can be defined as the sum of the discharge time lag and the duration of discharge current. If the addressing time increases, the sustaining period for display image should be decreased. As a result, the luminance of the PDP decreases. Therefore, the discharge time lag and duration of discharge current should be decreased in order to reduce the addressing time. In this paper, in order to improve addressing time, relationships between addressing time and cell structure in AC PDP was studied

ADS(Address Display period Separation) driving method has been considered to be the most appropriate driving technique for AC PDPs. However when the ADS driving method is applied to the high-resolution AC PDP, the required long addressing time often becomes a problem. In this paper, we present a new waveform for reducing the addressing time and for the stable addressing discharge. In this new waveform, a wall charge acceleration pulse is applied to the common electrode right after 80us scan time. In this way, the charge generated by the addressing discharge is accelerated to the electrodes. Experiments using the wall charge acceleration pulse showed that we could stably address an AC PDP with the scan pulses having pulse width of 1 us

The charged particle type display is a kind of electronic paper showing information images using positive and negative charged particles ($<10{\mu}m$). In this work we used yellow(-) and black(+) particles which are respectively addressed to the cells of a upper and a rear substrate by using electric field. Our independent addressing method has strong points compared to the mixed particle putting method. The packaging with two orthogonal substrates and the aging process is followed by addressing process. The panel is sequentially driven by matrix method for each 4-unit cells. Layers of particles are controlled by barrier ribs and must be addressed to minimum 2 layers.

This paper proposes a distributed borrowing addressing (DIBA) scheme to solve problems of failure in address assignments resulting from limited tree depth and width when the distributed address assignment mechanism is used in a ZigBee/IEEE 802.15.4 wireless sensor network. DIBA is a method of borrowing addresses from neighbor nodes for newly entering nodes and assigning the borrowed addresses. Its network or sensing coverage can increase with almost the same overhead as the existing method. DIBA is a simple and lightweight means of addressing and routing, making it suitable for wireless sensor networks. Simulations showed that DIBA is a distributed addressing scheme with consistently excellent performance.

The well-blown address matching technology developed by the U.S. Census Bureau was applicable only for street addresses. However, many other addressing systems on the basis of a hierarchy of areas (hierarchical areal addressing system), such as Korean or Japanese addressing system, cannot be suitable for the existing address matching method. This paper, therefore, develops an areal address matching method, especially for Korean addressing system, in order to geocode 2D and 3D locational data of human activities. Thus, this study explains a new approach to dealing with 3D positioning method composed of two geocoding methods, which are a '2D Korean Address Matching' technique and a '3D Address Matching' technique.

Reset is necessary for effective addressing in AC PDPs, but reset takes considerable time and produces background luminance. A reset method that takes less time but is effective for addressing is presented. Furthermore, this reset method produces almost negligible background luminance.

Irregular addressing scheme of gray scale control for the memory type flat panel plasma display is proposed in this paper. Opposed to the conventional addressing method. the scan electrodes are addressed in non-sequential manner. The addressing order for this irregular addressing is resolved to make the pixel duty factor above 90%. This addressing scheme can achieve the prolxJsed peformance regardless of the panel and cell structure and can be implemented without increasing the chive voltage, current or frequency .

The addressing time should be reduced by modifying cell structure and/or driving method in order to replace the dual scan system by single scan and increase the luminance in large ac plasma display panel(PDP). In this paper, the effects of the addressing time was decreased with decreasing thickness of dielectric layer on the front glass and thickness of white dielectric layer on the rear glass. the decreasing rate were 160ns/10$\mu\textrm{m}$ and 270ns/10$\mu\textrm{m}$, respectively Also in case of decreasing the height of barrier rib, addressing time was decreased at the rate of Sons/10$\mu\textrm{m}$.
