The small pitch LED display has been favored by people because of its unique high brightness, wide color gamut, high contrast and other advantages. At the same time, the problem of light bio-safety of the human eye with a small-pitch LED display has also received attention.
According to the current international standards, the China Institute of Metrology measures the bio-safety of a P1.67 small-pitch LED display from both retinal blue light hazards and thermal hazards, and selected plasma TV and LCD TV prototypes. As a comparison.
The test results show that in 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 characteristics of the narrow band make it possible to obtain the retinal hazard index obtained after weighted integration. No higher than plasma TVs and LCD TVs, there are no significant differences in the retinal biosafety measurement data of the three different display screens. In the three samples, the LED display measurement results are even better than the other two kinds of display screens.
It should be noted that any long-term viewing of the display screen may cause permanent damage to the human eye. Therefore, regardless of the type of display screen used, the operating personnel should pay attention to eye health, develop good eye habits, and work and rest. Combine, consciously and actively protect vision.
