Though bottom emission AM-OLED has advantages in respect of mass production, the bottom emission type is underrated due to its low aperture ratio and low color gamut, compared with top emission type. In this paper, we demonstrate that the color gamut up to 89 % can be simply achieved by depositing dielectric multilayers, whose thicknesses are determined using an optical simulation program, prior to formation of Si layer.

Blue-white reflective cholesteric liquid crystal display was prepared by a unique method of single liquid crystal layer, the combination of yellow color liquid crystal and blue color backplane. The dopant and host combination of chlolesteric liquid crystal affects the color spectrum. The CIE chromaticity coordinates of blue and white are (0.10, 0.16) and (0.29, 0.30), respectively. The relatively low driving voltages of 32 V for blue-white display are obtained.

The color electronic paper display panel, which is fabricated with about $300\;{\mu}m$ width of each color pixel strip and is possible to integrated into a fundamental full-color flexible display prototype, is presented. The monolayer of close-packed color electrophoretic microcapsules is formed on the ITO electrode. The color pixel strips are composed of each color electrophoretic microcapsules (i.e., cyan, magenta, yellow, and black).

The solution way of color difference in display device is using a device profile recorded with color dimension, color properties of each device and is using sRGB color space. The color matching is better sRGB than RGB color space. The sRGB is independent device color space and based on the monitor characteristice. An accurate characterization of the display device is essential for color matching. The calibration and characterization process in display device is needed to transform the device dependent color to the device independent color. The process of characterization performs a linerizaiton and transforms the linearized values into the CIE XYZ tristimulus values. The purposes of this paper is to estimate color reproduction using device profile and to explain the propriety of transformation method using variable.

A new dithering algorithm, "Hi-FRC", to enable full (16,777,216) color display on LCD panel with 6-bit source D-IC's is presented. The conventional FRC can display only 16,194,277 colors. In addition, The LCD panel with Hi-FRC can meet the color grayscale linearity of TCO '03 because it can improve the color shift problem.

색 정보 전달의 호환성을 위해 채택된 sRGB 색공간은 수많은 컴퓨터 시스템 및 주변 멀티미디어 장치들에 효율적인 색 정보 전달을 가능하게 한 표준이다. 하지만 현재 우리가 일반적으로 사용하고 있는 디스플레이 모니터는 sRGB의 표준과 다른 비 표준 삼원색과 감마 특성을 가지고 있다. 본 논문에서는 비표준 디스플레이를 sRGB 표준의 화상 색에 좀 더 가까운 색을 재현하기 위한 오차 보정 행렬을 제안한다. 제안한 색도 오차 보정 행렬을 이용한 방법을 적용한 실험 결과, 비 표준 디스플레이에 재현된 영상에서의 색 재현 오차가 감소하는 것을 확인할 수 있다.

In this study, we fabricated high quality color conversion component with green/red phosphor and low melting glass frit. The color conversion component was prepared by placing the green and red phosphor layer on slide glass via screen printing process. The properties of color conversion component could be controlled by changing coating sequence, layer thickness and heat treatment temperature. We discovered that optical properties of color conversion component were generally determined by the lowest layer. On the other hand, the heat treatment temperature also affected to correlated color temperature (CCT) and color rending index (CRI). The color conversion component with a green (lower) - red (upper) layer which was sintered at $550^{\circ}C$ showed the best optical properties: CCT, CRI and luminance efficacy were 3340 K, 78, and 56.5 lm/w, respectively.

Two different kinds of subjects are discussed. One is " Enhanced color space for displays" and the other one is"An application for large format displays". Originally defined color space by NTSC has never been used widely for TVs and information displays as there have been no available display devices. LCD panels with new light sources for backlighting will provide much wider color space. LCD monitors which use these new panels will meet almost 100% with the color space defined by NTSC or Adobe. Now, It is the time to deploy wider color space defined by such as the NTSC or Adobe as the standard of LCD display panels. As the large format display devices with reasonable price have not been available till plasma panels became available, application of these panels as an information display in public space is a quite new experience for us. Various kinds of practical applications are observed and coming out. It will generate many and new types of businesses.

본 논문은 표준 디스플레이를 이용한 OLED의 색재현성 모델링을 제안한다. 비표준 RGB 디스플레이의 종류는 매우 다양하게 있으며, 그 색 재현 특성은 삼원색 좌표와 기준 백색 좌표 등 여러 가지 요인에 의해서 다르게 나타난다. 본 논문에서는 변환 매트릭스를 이용하여 OLED 디스플레이의 색 재현 특성을 표준 디스플레이에 재현할 수 있는 알고리듬을 제안한다. 본 연구에서 제안된 알고리듬을 이용하면, 색 재현 특성을 사전에 시뮬레이션으로 확인할 수 있으므로, 기존 디스플레이의 성능 향상이나, 새로운 디스플레이를 개발할 때 매우 유용하게 쓰일 것으로 기대된다.
