Remark

1 Software controls the blue light emission by reducing excessive blue light, resulting in a
more yellow tone.
2 Color gamut describes the availability of colors in the display. Various standards were
developed for specific purposes. 100% corresponds to the full color space as defined in the
standard.
3 NTSC stands for National Television Standards Committee, which developed a color
space for the television system that is used in the United States.
4 sRGB is a standard red, green, and blue color space that is in use on monitors, printers,
and the World Wide Web.
5 DCI-P3, short for Digital Cinema Initiatives - Protocol 3, is a color space used in digital
cinema that encompasses a wider range of colors than the standard RGB color space.
6 Adobe RGB is a color space created by Adobe Systems that encompasses a broader
range of colors than the standard RGB color model, particularly in the cyans and greens.
