What does notebook color gamut mean?

Color gamut is a method of encoding a color. Laptop color gamut refers to the color range that can be displayed by a computer screen monitor. There are three common color gamut standards: 1. sRGB, which is a color language protocol jointly developed by Microsoft and HP, Mitsubishi, Epson and other manufacturers. It is the color space supported by default by current Windows systems and many native software; 2. RGB, Color space launched by Adobe in 1998; 3. NTSC refers to the sum of colors under the NTSC standard.

Color gamut is a method of encoding a color, and also refers to the total number of colors that a technical system can produce. In computer graphics, a color gamut is a complete subset of colors. The most common application of color subsets is to accurately represent a given situation. For example, a given color space or the color rendering range of an output device.

The notebook color gamut refers to the color range that can be displayed by the computer screen monitor.

There are three common color gamut standards, namely sRGB, Adobe RGB, and NTSC. Currently, the common color gamuts for laptop screens on the market are 45% NTSC, 72% NTSC and 100% sRGB.

NTSC color gamut is the United States National Television Standards Committee. The NTSC television standard they introduced is a set of broadcast and television transmission protocols that are widely used in the television industry. .

sRGB (standard Red Green Blue) is a color language protocol jointly developed by Microsoft and HP, Mitsubishi, Epson and other manufacturers. It can be applied to the color space currently supported by default by Windows systems and many native software. Laptops, cameras, scanners, projectors, and printers all support the sRGB color gamut, and almost all content on the Internet is based on sRGB. Therefore, sRGB has the highest versatility in today's Internet era.

Adobe RGB is a color space launched by Adobe in 1998. In order to include both sRGB (a color space commonly used in computers) and CMYK (a color space commonly used in printing), its purpose is to enable the excluded photos not only to be displayed on the computer Normal display on the monitor can also be used to print correct colors without loss. Adobe RGB includes a wider color range than sRGB and is mainly used in professional photography and post-production fields. If other people's equipment cannot display such a wide color gamut, you will not see any difference in your work.

DCI-P3 (also used by many mobile phones) is a standard with a richer color gamut than NTSC. The Apple MacBook Pro screen uses the P3 color gamut, so the look and feel on Apple devices will be richer than the ordinary color gamut, and with high-resolution support, the look and feel is very good. From this point of view, Apple's color performance is not bad. But

For the two most commonly used standards, NTSC and sRGB, NTSC can describe more colors. sRGB is almost completely included in the NTSC color gamut, and sRGB is roughly only 72% of NTSC. NTSC has a much larger color gamut than sRGB, and 100% sRGB is equivalent to 72% of the NTSC color gamut value.

The most critical issue is that the color gamut standard color range of different devices is different, so it is not that the larger the color gamut, the better the supported color gamut. For Windows notebooks, the sRGB color gamut is the best supported color gamut. Therefore, for Windows, choosing a 100% sRGB screen can be used universally on various devices without causing color differences. If you draw a pattern on a 45% NTSC screen, it will appear a mess on another 100% rRGB device.
