32"-diagonal gated carbon nanotube(CNT) cathodes named under-gate cathodes for large-size display applications have been fabricated and characterized. The emission uniformity looks fine, even without the resistive layer. The emission performance has been improved by scaling down the cathode electrode dimension.

The first 9-inch carbon nanotube based color field emission displays (FEDs) are integrated using a paste squeeze technique. The panel is composed of 576 x 242 lines with implementation of low voltage phosphors. The uniform and moving images are achieved only at $2V/{\mu}m$, This demonstrates a turning point of nanotube for large area and full color applications.

MgO thin film is widely used in PDP panel for protecting the dielectric layer and making firing voltage low. In this paper, the MgO thin film and discharge characteristics was analyzed as hydrogen flow rate increasing. Using hydrogen in deposition chamber makes add delay time of PDP module longer or shorter. It is the reason why thin film surface layer thickness on the MgO surface changes.

The antiferroelectric liquid crystal display (AFLCD) is unique display that can show the perfect moving image using the passive matrix driving scheme. We optimized the driving waveform and introduced the dual driving method. Also, by improving this driving method and using line inversion method, we realized AFLC display with high image quality, which has 160(RGB)${\times}$240, 32768colors, crosstalk free and flicker free. The contrast ratio is greater than 60:1, and the brightness is above 200cd/$m^2$.

Carbon nanotube emitters, prepared by screen printing, have demonstrated a great potential towards low-cost, largearea field emission displays. Carbon nanotube paste, essential to the screen printing technology, was formulated to exhibit low threshold electric fields as well as an emission uniformity over a large area. Two different types of triode structures, normal gate and undergate, have been investigated, leading us to the optimal structure designing. These carbon nanotube FEDs demonstrated color separation and high brightness over 300 $cd/m^2$ at a video-speed operation of moving images. Our recent developments are discussed in details.

동축 케이블에 영상, 음성, 데이터 등을 전송할 수 있는 SDI(Serial Digital Interface) 기술을 카메라에 적용한, HD-SDI 카메라는 다양한 SDI 장치 및 제품들과의 호환성이 중요하다. 즉, 각각의 SDI 장치 및 제품들이 표준을 준수하여 호환성을 유지해야 상호간 동작에 문제가 없게 된다. 현재, HDcctv Alliance에서는 각각의 SDI 장치 및 제품들을 특성별로 구분하여 그에 따른 표준을 정해 놓았다. 각각의 SDI 장치 및 제품들이 상호간의 올바른 동작을 하기 위해서 각각의 표준을 준수하면서 제품을 만드는 것은 중요하다. 본 논문에서는, HDcctv 표준을 준수하는 카메라 시스템을 구현하였으며, HDcctv 표준에 따라 설계를 하여, HDcctv Alliance의 인증을 받기 위한 모든 데이터를 측정하여 표준에 맞는 결과를 얻었다.

Dual Mode technology has been developed as a new technology that allows to use a self-emissive display under full sunlight conditions. The new technology connects a LCD-like remissive operation mode in sunlight to an OLED-like self-emissive operation in the dark In the recent years, the focus of development has shifted towards the possibility of full colour operation.

The concept of a Spatial Data Infrastructure (SDI) has emerged globally to facilitate the transit of spatial information from data producers to a vast and ever-growing community of users. SDI have become very important in determining the way in which spatial data are used throughout an organization, a nation, different regions, and the world. SDI is an initiative intended to create an environment in which all stakeholders can cooperate with each other and interact with technology, to better achieve their objectives at different political / administrative levels. Islamic Republic of Iran began her participation in the Global map project and SDI activities in 1998. In this related, National Cartographic Center (NCC), as the representative of Iran, started the job with identifying the suitable sources of data for creation of those layers stated in the specifications of Global Mapping. NCC started making GIS Users Councils (National & Provincial Councils) for the making National SDI and Local SDI too. Now, NCC is doing some activities to joining its National SDI to Regional and Global SDI. This paper in first section, discuss about SDI as basic point in Information Technology (IT). In second section, SDI situation in IRAN and National Cartographic Center’s roles in realization of future scope of RSDI and GSDI is discussed. (NCC is one of the greatest Map Producer organizations in IRAN). The way that be applied, is analyzing of fundamental points especially Sustainable development, IT and SDI and their complementing policy in Information Society. These include some applications in National, Regional and Global levels.
