The reason why high-end full-color LED displays use pure green tubes is mainly based on their luminous efficiency and color rendering effect. In the actual production process of LED display screens, in order to ensure that the color triangle area in the chromaticity diagram is as large as possible and close to the tongue-shaped color spectrum curve, in order to achieve rich colors and sufficient brightness, we choose products with high luminous efficiency and bright colors. Three primary color LED tubes are the key. The top of the tongue-shaped spectral color curve corresponds to the 515nm wavelength light. Therefore, high-end full-color LED displays will specifically use pure green light LED tubes with wavelengths close to 515nm, such as 520nm, 525nm or 530nm wavelength light LED tubes.
In addition, the high luminous efficiency of pure green tubes also provides strong support for its application in high-end full-color LED displays. By adjusting the brightness and color mixing ratio of the three basic colors of red, green, and blue LEDs, the full-color screen can display millions of colors and present colorful images and videos. The high brightness and color rendering effect of the pure green tube can further enhance the display effect of the full-color screen, making the image more vivid and realistic.
To sum up, high-end full-color LED displays use pure green tubes to meet their needs for high luminous efficiency and rich color rendering, thereby providing better visual effects.
