Whether Full Color LED Display Will Hurt the Eyes or Not?
High-density full-color LED display because of its unique high brightness, wide color gamut, high contrast and other advantages in many occasions by the people of all ages. At the same time, high-density LED display on the human eye light biosafety issues have also been people's attention.
China Institute of Metrology, based on the current international standards, from the retinal blue light hazards and thermal hazards in two aspects, a P1.66 high-density LED display light biosafety was measured, and selected the plasma TV and LCD TV prototype As a comparison.
The test results show that in the same brightness and white field conditions, in the blue band, although the peak brightness of the LED display is higher than the other two samples, but its narrow band characteristics make it weighted after the retraction of the retinal hazard index No more than plasma TV and LCD TV, three different display retinal photobiological safety measurement data no significant difference, three samples, LED display measurement results even better than the other two kinds of display.
It should be noted that any display long-term viewing of the human eye are likely to cause permanent damage, so no matter what form of full-color display, the operating staff should pay attention to eye health, develop good habits, Work and rest, consciously, take the initiative to protect the vision.
