The high-density full-color led display has been favored by people for its many advantages such as high brightness, wide color gamut and high contrast. At the same time, the high-density 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 P1.66 high-density 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 higher than plasma TV and LCD TV, there is no significant difference between the three different display retinal biosafety measurement data. Among the three samples, the LED display measurement 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, regardless of the form of full-color display, the operating personnel should pay attention to eye hygiene and develop good eye habits. Work and rest, consciously and actively protect your vision.
