What is a high color gamut LCD monitor
Gamut is a concept that describes the range of color space, which represents the range of colors that a device or system can present. The breadth of the color gamut determines the diversity of colors we see on screens, printers, or other devices. In short, the wider the color gamut, the more colors the device can display or output, and the richer the color expressiveness of the image. Understanding the concept of color gamut and its application in display technology is of great significance for the correct selection and use of display devices.
In 1931, the CIE International Lighting Association proposed a CIE-XYZ color gamut color map. In the figure, x represents the red component, y represents the green component, and the blue component can be calculated using (1-x-y); the E point in the middle represents white light, and its coordinates are (0.333, 0.333). The color surrounding the edge of the color space is spectral color (or spectral color), the boundary represents the maximum saturation of the spectral color, and the numbers on the boundary represent the wavelength of the spectral color. All monochromatic light is located on the tongue curve, which is a monochromatic trajectory, and the numbers marked next to the curve are the wavelength values of monochromatic light; all kinds of colors visible to human eyes in nature are located in this closed curve. The standard of color gamut is based on different definitions of color space. Common color gamut standards include sRGB, Adobe RGB and DCI-P3. sRGB is a color gamut standard widely used in displays, printing equipment and the Internet, formulated by the International Electrotechnical Commission (IEC), covering about 35% of the colors visible to the human eye. Compared with sRGB, Adobe RGB can present more green and blue tones, making it suitable for professional photography and printing. The DCI-P3 standard is mainly used in film production and can present richer reds and greens. It is one of the important standards for modern high-end displays and TVs.
The color gamut of the display refers to the range of colors that the display can display. The color gamut of the display on the market is mostly marked as a percentage, indicating the proportion of a certain color gamut standard that the display can cover. For example, if a monitor claims to have 100% sRGB color gamut, it means it can fully display all colors under the sRGB definition. With the advancement of display technology, the color gamut coverage of the display has gradually increased, which allows users to obtain a more realistic and vivid color experience when viewing images and videos. High gamut displays usually refer to monitors with higher gamut coverage, which can present more color details and color depth than standard gamut displays. The implementation of high color gamut requires more advanced display technologies, such as LED backlight color gamut improvement, quantum dot technology, OLED panels, etc. These technologies can significantly improve the color expression of the display, especially when it comes to high saturation colors such as red and green.
