LED Wavelength Control Range

- Jan 13, 2021 -

The wavelength determines whether the color is pure or consistent. The solution is simple; User does not have professional equipment commonly, how to distinguish with the eye?


First: the whole screen is white, the screen should be pure white, without any other noise. If you think it doesn't matter if you're a little red or blue, you're wrong, because the color bias is evidence of a problem with the display's materials and quality control. Over time, it will become more and more serious.


Second: red, green, blue monochrome, the center wavelength of the color is usually we say is blue, red and green, if a little deeper or a little light color, it is proved to be a partial wavelength. If a certain color is inconsistent, it is proved that the wave difference is too large. The blue-green wave difference is controlled at 3nm and the red wave difference is less than 5nm for a high-quality display screen within the range of the central wavelength.
