Everyone knows that LCD display screens have many parameters, and for those who don't understand the parameters, it will definitely be a headache for them to face this pile of symbols. As a manufacturer of high brightness display screens, technology today will teach you what is the color gamut coverage of LCD display screens.
Color gamut: refers to the range of colors that a display system can express.
In order to visually represent the concept of color gamut, the CIE International Illumination Association has developed a method for describing color gamut: the CIE xy chromaticity chart. In this coordinate system, the color gamut range that each display system can represent is represented by a triangular area formed by RGB three-point lines. The larger the area of the triangle, the larger the color gamut range of this display device.
Color gamut coverage: The horseshoe chromaticity triangle marked with colors on the CIE xy chromaticity chart is the color area visible to the human eye. If a system can reproduce all the colors in this horseshoe area, it can be said that its color gamut coverage is 100%. When using the three primary colors R, G, and B to reproduce colors, the triangular area formed by the coordinates of R, G, and B is the color reproduction area determined by these three primary colors. The ratio of this area to the horseshoe shaped area is the color gamut coverage. So, color gamut coverage is the ratio of the area of a triangle formed by the three primary color coordinates R, G, and B to the area of a triangle formed by the standard R, G, and B primary color coordinates.
