Small-pitch LED displays have been favored in many occasions due to their unique high brightness, wide color gamut, and high contrast. At the same time, the small-pitch LED display has also attracted people's attention to the photobiosafety of the human eye.

According to the current international standards, China Institute of Metrology has measured the photobiosafety of a P1.67 small-pitch LED display from two aspects of retinal blue light hazard and thermal hazard, and selected plasma TV and LCD TV prototypes. As a comparison.
The test results show that under the same brightness and white field conditions, although the peak brightness of the LED display is higher than that of the other two samples in the blue light band, the narrow band characteristics make the retinal hazard index obtained by weighted integration. No more than plasma TVs and LCD TVs, there is no significant difference in the biosafety measurement data of the three different display retinas. Among the three samples, the LED display is even better than the other two displays.

It should be noted that any long-term viewing of the display may cause permanent damage to the human eye. Therefore, no matter what form of display is used, the operating personnel should pay attention to eye hygiene and develop good eye habits. Combine, consciously and actively protect your vision.
