25.4: Six‐Primary‐Color 23‐ in WXGA LCD using Six‐Color LEDs

The authors have successfully developed a six-primary — color LCD using six-color LEDs. More specifically, a prototype of a six-primary color LCD having a color gamut of 170% or wider than that of conventional techniques has been realized. This research was organized in part by the New Energy and Industrial Technology Development Organization, Japan (NEDO).

P-24: LCD Module Adopting a Color Conversion Circuit

The authors have developed a LCD module that adopts a color conversion circuit which can contribute to the improvement of imperfect color reproduction in the LCD panel. The new module adopts a color conversion circuit that uses a new matrix calculation which we have developed. This color conversion circuit allows support of motion picture display and real time processing. In addition, it enables realization of desired color conversion characteristics and it also facilitates realization of use of two or more types of color conversion characteristics by selection.

43.5L: Late News Paper: Prototype of a Wide Gamut Monitor Adopting an LED-Backlighting LCD Panel

This paper presents development of a wide color gamut monitor that has 104.4 [%] color gamut comparing to NTSC color gamut. In this paper we would like to report about a prototype of wide color gamut monitor. And more we have compared color gamut of our prototype vs. some major set of standard color patches. We would like to also touch upon this comparison. Specifications of our newly developed monitors are as follows: (1) Color gamut; more than 100 [%] for NTSC, (2) Screen size; 22 [inches] (480mm * 288mm), (3) Resolution; WXGA (H; 1280 * V; 768 [pixels]), (4) Maximum brightness; more than 600 [cd/m2] and (5) liquid crystal mode; IPS (In-Plane-Switching). (6) Supporting the bi-directional communication function called DDC/CI (Display Data Channel Command Interface). We believe that our monitor is useful for soft proofing of DTP as replacement of conventional CRT displays. This research is organized in part by NEDO (New Energy and Industrial Technology Development Organization, Japan).

19.3: Laser TV: Ultra‐Wide Gamut for a New Extended Color‐Space Standard, xvYCC

We have developed an HDTV that adopts semiconductor lasers involving three primary colors, red, green and blue for the light source. The adoption of a laser light source helped us realize a HDTV with a dramatically wide color gamut, namely 190% the color gamut of ITR-U BT.709. In addition, we have also developed an LSI that can deal with an extended color space xvYCC, which is a new international standard, and mounted the LSI in the HDTV. The display of colorful and natural video pictures has been achieved through the effective use of the wide color gamut involved in the laser light source supported by a video signal processing circuit that complies with the xvYCC standard and Natural Color Matrix, a color management technique.

Wide Color Gamut and High Brightness WUXGA LCD Monitor with Color Calibrators

Authors have developed a wide color gamut and high brightness WUXGA LCD monitor with color calibrators. This monitor has the worlds highest performance level for color gamut and brightness for a UXGA rating or greater (number of pixels). This monitor provides the necessary performance in fields requiring advanced color control, such as DTP, prepress operations, printing and moving images. This paper describes the background of the development, technical problems and the results of evaluation.

41.4: Late-News Paper: Wide Color Gamut and High Brightness Assured by the Support of LED Backlighting in WUXGA LCD Monitor

The authors have successfully developed a WUXGA LCD monitor that has the worlds highest performance level for color gamut and brightness for the number of pixels equal to or greater than UXGA. It provides a color gamut of approximately 150 [%] of conventional CRTs, and further, our monitor assures the high brightness of 600 [cd/m2] or greater. This research was organized in part by the New Energy and Industrial Technology Development Organization, Japan (NEDO).

Six-primary-color LCD monitor using six-color LEDs with an accurate calibration system

The authors have successfully developed a six-primary-color liquid crystal display using six-color LEDs. More specifically, a prototype of a six-primary-color liquid crystal display having a color gamut of 170% or wider then that of conventional techniques has been constructed. Furthermore, this monitor has a newly developed calibration system using an integrated color sensor, so that it can keep its white point chromaticity stable.

Wide-color-gamut monitors: LED-backlighting LCD and new phosphor CRT

The authors have developed two types of wide color gamut monitor and compared their characteristics. This paper provides an introduction to the color reproduction and standard color space of displays as well as an interpretation of the two types of typical wide color gamut displays that are currently under development. The CRT displays with a wide color gamut are rich in gray levels and viewing angle characteristics while the LCD displays with a LED backlight style have high brightness performance and a broad color gamut. Both types of display support the color gamut of Adobe RGB, enabling compatibility with the extended color space, now beginning to be disseminated, and they also provide a breakthrough for industries that need color management.
