What is the color saturation of a liquid crystal display

Saturation (saturation) is one of the components of color, and it is a project that photographers attach great importance to.

The so-called saturation, refers to the purity of the color, the higher the purity, the more distinct the performance, the lower the purity, the performance is more bleak, in English, saturation and chroma is the same thing.

Traditional well-known color systems such as Munsell, din of Germany, Nature Color in Sweden, OSA in the United States, and Cosmos in Japan. When they classify and generalize color systems, they are mostly based on three attributes of color-hue, saturation, and brightness.

The color saturation of the liquid crystal (color gamut), also known as the liquid crystal opening rate (Aperture Ratio). It represents the brightness of the color of liquid crystal display, is a very important parameter of LCD products.

Color saturation is based on the color range of the three primary colors of the display as a molecule, NTSC the three primary colors of the color range of the denominator, the percentage. If a display has a color saturation of "72%NTSC", it indicates that the display can display a color range of 72% of the NTSC rule.

Because each pixel of liquid crystal is composed of red, green and Blue (RGB) sub-pixel, the backlight can be combined into any color light by RGB pixel after the LCD molecule. If the RGB three primary colors are more vivid, then the display can represent a wider range of colors. If the three primary colors of the monitor are not bright, then this display can display a narrower range of colors, because it does not show more vivid colors than the three primary colors. Improve the color saturation of the method is to improve the brightness of the back and liquid crystal light, which requires a higher technology and cost manufacturers, the market on various types of liquid crystal display grades, its bright degree is also very different, at present the highest standards for 72%NTSC.
