When buying a TV,We often see some propaganda about the color gamut value,For example"Up to92%NTSC color gamut",This seems to have become an important indicator of TV performance。 However, do you really understand what the color gamut value means, and is a wide color gamut TV really right for you?
First of all, we need to understand that the higher the color gamut value, the higher the richness of color expression. At present, the color gamut range of mainstream LCD TVs is generally 72%NTSC color gamut。 Color gamut is the method of encoding a color, and also refers to the sum of colors that a technical system can produce, i.e., a region of the color space.
However, a wide color gamut isn't always better. The colors in the visible spectrum in nature make up the largest color gamut space, which contains all the colors that the human eye can see. The artificially created color range of TV is relatively limited, and the three colors are connected to each other in the general display red, green and blue (that is, the common RGB), and the internal area of the triangle enclosed is the color gamut, which cannot completely cover all visible light color ranges.
As a result, wide color gamuts require good color management to be advantageous and effective. Users can't blindly pursue data when buying TVs,It is also necessary to combine the adjustment of the product itself and their own needs。
For example, the international standard of 92% NTSC color gamut is called wide gamut (high color gamut). The high color gamut enables the TV to display richer colors,The color transition in the picture is more natural,The sense of hierarchy is more distinct,It can show more details and closer to the real effect,It can effectively avoid distortion and color blocks。 However, if you don't need such a high color performance, then a wide color gamut TV may not be for you.
In general,When buying a TV,We can't just look at the data of color gamut value,We also need to make a choice based on our actual needs and product characteristics。 Only in this way can we really choose the right TV for ourselves.
