Color revolution: toward ultra-wide color gamut displays
Journal of Physics D: Applied Physics, 2021Abstract With the economic and social developments, the demand for higher quality displays has always remained strong. The emerging 8K displays represent an advancement of ultra-high resolution. Other parameters such as the contrast ratio and viewing angle were all improved significantly.

A Gamut Preserving Color Image Quantization
14th International Conference of Image Analysis and Processing - Workshops (ICIAPW 2007), 2007We propose a new approach for color image quantization which preserves the shape of the color gamut of the studied image. Quantization consists to find a set of color representative of the color distribution of the image. We are looking here for an optimal LUT (look up table) which contains information on the image's gamut and on the color distribution

P‐39: A Novel Color Gamut Quantization Method for Wide Color Gamut Display
SID Symposium Digest of Technical Papers, 2014Abstract In this paper, we propose a novel method to calculate the color gamut especially for wide color gamut display. The features of the proposed method are 1) luminance consideration, 2) large color space and 3) distinguishable color by human eyes.

Asymmetric nanocavities with wide reflection color gamut for color printing
Nanotechnology, 2022Abstract Symmetric metal-dielectric-metal (MDM) nanocavities based on Fabry–Perot resonance play a crucial role in transmission colors. However, their reflection color gamuts are generally limited owing to the narrow dip of resonance spectrum.

Color Gamut Scalable Video Coding
2013 Data Compression Conference, 2013This paper describes a scalable extension of the High Efficiency Video Coding (HEVC) standard that supports different color gamuts in an enhancement and base layer. Here, the emphasis is on scenarios with BT.2020 color gamut in an enhancement layer and BT.709 color gamut in the base layer.

ACM SIGGRAPH Computer Graphics, 1978
Digital control of color television monitors—in particular, via frame buffers—has added precise control of a large subset of human colorspace to the capabilities of computer graphics. This subset is the gamut of colors spanned by the red, green, and blue (RGB) electron guns exciting their respective phosphors.

Overview of Color Gamut Scalability
IEEE Transactions on Circuits and Systems for Video Technology, 2017Displays’ new rendering capabilities combined with the ever-growing number of video applications have fueled the emergence of new video formats addressing wider color gamut and larger frame size. Thus, the need in scalable compression technology to provide backward compatibility with legacy devices and capitalize on the superior compression performance

Color Gamut of Liquid Crystal Polysiloxanest
Molecular Crystals and Liquid Crystals, 1985Abstract Polysiloxanes with suitable side-chains form a cholesteric liquid crystal phase that can be applied to a substrate to produce a durable coating which exhibits strong colours below the glass transition temperature. The peak reflectance is almost 0.5 and a nearly 1.0 peak reflectance can be obtained using a half-wave retardation plate coated on ...

Gamut mapping algorithms, implemented by color management systems, are an integral part of the color reproduction process. By adjusting the colors with appropriate algorithms, gamut mapping enables original colors to fit inside differently shaped color gamuts and authentically transfers images across a range of media. This book illustrates the range of

Large color gamut displays with diffraction gratings
Journal of the Optical Society of America A, 2016The ability to display a broad variety of colors has great benefits not only in the context of entertainment but also as a means to streamline design in prototyping and manufacturing processes. Displays that use RGB filters or backlights cannot span all colors that occur in nature. To improve the accuracy of color reproduction, there have been attempts
