We have developed a 3.1-inch diagonal 2D/3D LCD with a novel pixel arrangement, called HDDP (Horizontally Double-Density Pixels), for high-quality 3D images. We have improved 3D visibility by broadening the 3D viewing zone where high-quality images can be seen, and we propose optical characterization methods which can evaluate the high-visibility autostereoscopic displays correctly.

The high speed and sensitivity array test system has been developed and utilized for massproduction of advanced LTPS displays including SOG and OLED. It realizes fast enough TACT enabling 100% inspection with better than 1fF sensitivity. The result of actual measurement shows its superior TACT and sensitivity, and also shows MURA detection of OLED panel.

Today, ubiquitous technology (e.g. computers or networked devices pervade everywhere we are) has enlarged by great advancement of information and communication technologies. If ubiquitous technologies is applied to, innovation of spatial information technology is expected. traditional spatial information technologies such as survey, GIS, GPS, LBS, and RS and ubiquitous technology gradual1y have been converged. The aim of this study is to create shared visions in spatial information technologies by scenario based roadmapping. So, we surveyed the state of the art in main spatial information technologies, market status and patent map. Consequently, prospects of spatial information technologies is suggested. The aim of 1st and 2nd NGIS project focused on map supplier was to develop digital map(e.g. framework data, various thematic map). As a result, the best technology of digital mapping is achieved in the world. But, there is not enough to develop GIS and LBS solution. Current market in GIS S/W and Telematics is about 384billon won and 250billion won. a patent is applied in the order, like a USA(1571case, 47%), Japan(883case, 26%), EU(478case, 14%), Korea(446case, 13%). In the future, spatial information technology fused on ubiquitous technology will be focused on user's demand and developing convenience context. The developing target will be realtime monitoring of 3D spatial data based on high resolution coordinate system, sharing and supplying multi-sensor data considered users demand, location service by ubiquitous technologies.
