The toner type paper-like display (PLD) has been developed with two polymer particles having opposite polarity which is composed of polymer, colorant and external additives (nano-sized silica). Nano-sized silica with triboelectric charge was used for the charge control agent (CCA) and influenced on the electrostatic properties of the silica-coated polymer particles. The PLD cell using silica-coated particles (200 seconds) had shown a good white appearance and low driving voltage. The result could be explained in terms of the surface morphology and the cohesiveness depending on the silica coating time.

The distributions of mercury (Hg) in the bulb of a mercury vapor lamp are significantly affected by its turn-off conditions. Most of mercury should be attached to the electrodes before ignition by a proper turn-off condition. In the present study, the effect of the transient profiles of lamp cooling after turn-off on the distribution of Hg was investigated.

To reduce acoustic noise level of an AV projector, primary noise sources of AV projector were analyzed. Based on the analyzed result, methods to control each source are presented and tried. Structure-borne noise can be controlled by anti vibration design of mounting system, and air-borne noise by reducing flow resisitvity.

High Luminance PDPs have been developed using high efficient electrode structure, discharge gas and fishbone type barrier ribs. New phosphors for the good picture quality were developed. Also, New manufacturing processes such as CPBB were applied in order to reduce processing steps. High Luminance of 1,000 $cd/m^2$ was obtained in the series of 42 inch, 50 inch and 60 inch PDPs.

We present new ramp-reset waveforms that realize fast addressing in AC-PDPs. These waveforms distort the distribution of wall charges on the surface of a phosphor layer: hence, the enhanced electric field helps to ignite a cell faster. They also reduce the black luminance: the divide of erasing ramp down discharges into two parts, i.e. a surface discharge and a vertical discharge, makes lower luminance.

Korean digital product users' tends to be participationoriented. They hope that their expectations are reflected in the outcome. Furthermore, they look toward customizationoriented. They want product differentiation for only their own goods. They come to take a prudent and particular attitude. Korean display industry is under extending the share of the international market these days. This report covers the direction of the display industry design through analyzing the trend of the Korean digital product users'.

The characteristics of the sustain-driving circuit were examined in this paper. The sustain-driving circuit is in charge of the most important part of PDP driving because it manages most of the power consumption in the PDP. A couple of gatedriving circuits for the sustain-driving circuit were introduced in this paper, and a new driving circuit was also proposed. This new circuit is more cost-effective and has a simpler PCB layout compared to the conventional one. Some additional driving advantages were noted as well.

We have developed a new driving method named TROPHY(Talented Role-playing Technology with Dual Polarity sustainer in Hybrid Mono board). In this method, the sustain voltage is partially compared to the conventional method and the number of power sources is reduced by voltage level unification during the reset, address and sustain period. The hybrid mono board was especially developed to implement those technologies. Through this, we can lower the cost with the TROPHY compared to the conventional one. It is a suitable technology to improve the reliability of circuit and image sticking problem. We can also reduce the number of driving boards and the EMI problem compared with those of the conventional method.

디지털 정보 디스플레이(DID : Digital Information Display)는 공공정보 게시용 디스플레이 제품을 총칭한다. 최근에 유동인구가 많은 공공장소에 대형 디스플레이 패널을 설치하여 기업이나 상품의 광고 및 홍보 영상을 불특정 다수에게 제공하는 디지털 정보 디스플레이 방식의 광고들이 현저하게 늘고 있다. 본 논문은 효과적인 광고 제공시스템에 관한 것으로서 DID를 통해 광고하는데 있어서, DID가 위치하는 장소의 유동인구를 파악하고 분석하여 그에 따른 광고 운용 정보를 제공함으로써 광고주가 선택적으로 광고를 구매할 수 있는 광고 제공 시스템을 제안한다. 이러한 시스템을 통해 광고주에게 합리적인 비용을 제시하도록 하여 디지털 정보표시 수단을 통한 광고의 활성화를 기대할 수 있다.

Stereoscopic/autostereoscopic systems have been developed in order to express true 3D images, but have never had great success in the practical use. In order to apply 3D display to promising applications such as advertisements and games, we've developed a 42" 2D/3D switchable display. It has characteristics that don't require special glasses for 3D images, use multi-view technology for improving 3D viewing characteristics, and has a 2D/3D switching function to express dynamic 3D contents as well as conventional 2D contents.
