Super In Plane Switching (S-IPS) technology is applied for large TFT-LCD panels used in TV applications. It has a lot of advantages in comparison to the alternative, VA technology. S-IPS shows excellent viewing angle properties and fast response time between intermediate gray levels. If the performance parameters which describe the actual visual performance are considered, S-IPS is much more $advantageous.^{1)}$ However, it shows relatively low contrast ratio in diagonal direction compared to viewing angle characteristic in upper/down direction in S-IPS. In order to compensate the relatively low diagonal contrast ratio, Super-IPS applying for optical film developed, but Super-IPS still has the problem of color shift in black $pattern.^{2)}$ So we improved this problem by developing Enhanced Super-IPS.

The WV film successfully enlarged the field of view of the TN mode and made TN popular for larger size applications such as PC monitors. The hybrid alignment of the PDM (polymerized discotic material) layer is also suited for the OCB mode, which is promising as a nextgeneration LCD-TV because of fast panel response and a wide viewing angle. This paper describes recent technological progress in WV films, especially for OCB.

Numerous films and TV series worldwide have depicted characters with autism spectrum disorder (ASD) and savant skills. This study describes the portrayal of ASD and savant skills in Korean films and dramas. Starting with the 2005 film Marathon, characters with ASD have been featured in five films and four dramas. Most portrayals were based on the diagnostic criteria and pathogenesis of ASD, as outlined in the DSM-5. Of the 10 characters with ASD in these films and dramas, seven were male and three were female, with seven of them possessing savant skills. In the future, caution and guidance on the general characteristics of ASD from experts should be provided with the release of ASD-based films and TV dramas in Korea; in addition, critiques and social discourse pertinent to the reality of ASD should be provided by people with ASD, their families, and relevant experts.

We developed Super IPS mode TFT-LCD TV which have contrast ratio over 800:1. To increase contrast ratio, polarizer film, TFT design and color filter photoresist are investigated. In this report, we describe the basic concept and effectiveness of each item. The application of a newly developed color filter photoresist was the most effective for achieving this high contrast ratio.

We will discuss encapsulation of OLEDs on both flexible and rigid glass substrates. Accelerated testing at 6CC/90RH and 85C/85RH is compared and acceleration factors for OLED and Calcium test samples are discussed.We have tested the stability and performance of our barrier coating to much higher temperatures: up to 140 C. Water Vapor Transmission rates at temperatures from 60 to 140 C are presented. Rates and methods for low cost manufacturing on a large scale are analysed.

The detection technique both the polarization and the mobile charge density at the same time in ferroelectric films on Si using TVS method have been proposed. This method yields a polarizable and an ionic displacement current peaks whose areas are proportional to the total polarization reversal charge and the total moble ionic space charge, respectively. The calculated polarization and the mobile charge density were 0.42 [$\mu$C/$\textrm{cm}^2$] and 5.5$\times$10$^{11}$ (ions/$\textrm{cm}^2$) in the SBT film of MFIS structure measured at 25$0^{\circ}C$, and 1.4 [$\mu$C/$\textrm{cm}^2$] in the LiNbO$_3$ film of MFS structure measured at 30$0^{\circ}C$, respectively.

This study was started to not only resolve structural problems such as lack of contents, an unstable structure of earnings, and reduction of an additional market in Korean film industry through revitalizing digital cinema, but also make digital cinema become a power for growing Korean film industry furthermore. In the section of revitalizing digital cinema production, I suggest that expanding an audience base of low budget art cinema using digital technology will contribute to diversity film contents, and joint production with broadcasters by digital technology will expedite growing film industry as well as revitalizing digital cinema production. In the section of revitalizing digital cinema distribution, I insist, we should make effort positively to build reasonable hold-back and so on in order that film industry's positive participation in the market of digital film distribution and new media such as DMB or IP-TV may become an additional market to film industry. In conclusion, we can gain a foothold to leap toward a Position of cultural technology Power through efforts to resolve problems inherent in digital cinema.

본격적인 디지털 방송 시대를 앞두고 대형 TV 스크린에 대한 기술 개발 경쟁이 치열하게 전개되고 있다. 대형 디스플레이 소자로서 대표 주자인 Plasma Display Panel(PDP)의 양산에 한국, 일본 및 대만의 전자 업체들의 경쟁이 시작되었고, 이제는 30 인치 이상 대형 디스플레이로 상업화 가능성이 없었던 TFT(Thin Film Transistor) LCD(Liquid Crystal Display)가 40인치 이상의 TV 시장을 공략하기 위해서 대규모의 투자를 진행하고 있어서 PDP의 아성을 위협하기 시작했다〔1〕∼〔3〕.

In this paper, we describe the current status and issues of the oxide thin-film transistors (OTFTs), which attract much attention as an emerging new backplane technology replacing conventional silicon-based TFTs technologies. First, the unique benefits of OTFTs will be presented as a backplane for large-sized AMOLED including note-book PC, second TV and HD-TV. And then, the state-of-the-art transistor performance and uniformity characteristics of OTFTs will be highlighted. The obtained a-IGZO TFTs exhibited the field-effect mobility of $18\;cm^2/Vs$, threshold voltage of 1.8 V, on/off ratio of $10^9$, and subthreshold gate swing of 0.28 V/decade. In addition, the world largest-sized 12.1-inch WXGA active-matrix organic light emitting diode (AMOLED) display is demonstrated using indium-gallium-zinc oxide (IGZO) TFTs.

Television News has significant impact on the information analysis of viewers by delivering world news to anonymous individuals everyday. We need to pay more attention to resolution considering the fact that even slight facial expression and the dress of TV anchor can be noticed by viewers in the high definition age, called HD TV, by radical changes in broadcasting situation. As a result, the beauty of expression that lighting technology has is extremely important in the high definition age. In news broadcast, as a phenomenon according to this change in trend, people have been looking for change in order to break with traditional TV news production by adopting DLP(Digital Lighting Processing) or LED(Light Emitting Diode). This effort has contributed to creating proper picture quality appropriate for HD TV. Nowadays Digital imaging is creating new trend in TV news production method from traditional analog-based lighting environment thanks to the development of IT(Information Technology) and digitalized lighting equipment. This change has led to building of HD studio and appropriate sets and lighting system. There are film set and projector which projects image on the screen and PDP, LCD, and DLP which has been used widely in recent years and LED which is often used as background in news program as examples, which has appeared since 1990s with HD TV. In this article, I analyzed the KBS News 9 lnce 1990s with in order to research the influence of television image component on the alyzed the KBS of TV article, I. I wille uggest the category of TV anchor image formulation in delivering information by means of lnce 1990s with based on the analysis result.
