Question

Why do high-end full-color display screens use pure green tubes?

Answer 1

The main reasons why high-end full-color displays use pure green tubes are as follows:

1. Rich and bright colors: In the actual production of LED display screens, three-primary color LED tubes with high luminous efficiency and rich and bright colors should be selected. 

The wavelength of pure green light LED tubes is close to 515nm, which makes the color triangle area in the chromaticity diagram as large as possible and close to the tongue-shaped color spectrum curve, thereby satisfying rich colors and emitting sufficient brightness.

2. High brightness: The brightness of the LED screen will not fade over time and always maintains its original color. 

As one of the three primary colors, pure green tube plays an important role in improving the brightness of the entire display screen. 

Within the viewing distance, when sunlight hits the screen surface directly, the displayed content can be clearly seen.

3. Good color reproduction ability: The display effect of full-color LED display is better than that of LCD screen because of its high brightness, wide viewing angle and good color reproduction ability. 

Pure green tube, as a key element, plays an important role in improving color restoration ability.

4. High reliability: High-end full-color displays often use advanced digital video processing, distributed scanning technology, BSV LCD splicing technology for high-definition display, and pure green tubes, as part of them, have also undergone strict quality control. and testing, thereby ensuring the reliability and stability of the entire display.

To sum up, high-end full-color displays use pure green tubes in order to obtain richer and more vivid colors, higher brightness, better color reproduction capabilities and higher reliability.

Answer 2

In the actual production of LED display screens, three-primary color LED tubes with high luminous efficiency and rich and bright colors should be selected, so that the color triangle area in the chromaticity diagram is as close as possible to the tongue-shaped spectrum color curve. 

To satisfy rich colors and emit sufficient brightness, the top of the tongue-shaped curve is 515nm wavelength light, so high-end LED displays use pure green light LED tubes with wavelengths close to 515nm, such as 520nm, 525nm or 530nm wavelength light LED tubes.
