LED display is a mature product in our country. It mainly displays text content at the beginning, and then includes graphics and texts and dynamic videos. It is widely used in indoor and outdoor large-scale advertisements, stage performances, exhibitions, sports events, and hotel lobbies. And other occasions. The LED screen has the advantages of large display area, high brightness, bright colors, easy assembly, high utilization of building space, and low maintenance cost.

However, it was previously limited to technical bottlenecks such as the large pixel pitch of LED display and strong granularity when viewing images at close range, and failed to enter mainstream indoor mid-to-high-end mainstream applications. In recent years, with the development of technology, the semiconductor manufacturing process has become more and more mature, making the LED display dot pitch smaller and higher, and the resolution is getting higher and higher, and the small pitch LED display screen has emerged.
Small-pitch LED displays are favored by people in many occasions due to their unique advantages of high brightness, wide color gamut, and high contrast. At the same time, people’s attention has been paid to the photobiological safety of small-pitch LED displays to human eyes. Whether there is blue-light damage to the eyes of small-pitch LED displays is also one of the topics of concern. Bobangcheng will tell you below. the truth.

According to the current international standards, the Chinese Academy of Metrology has measured the photobiological safety of a P1.67 small-pitch LED display from two aspects: the blue light hazard and thermal hazard of the retina, and selected plasma TV and LCD TV prototypes. As a comparison.
The test conclusion shows that under the same brightness and white field conditions, in the blue band, although the peak brightness of the LED display is higher than that of the other two samples, its narrow band characteristics make the weighted integration of the retinal hazard index No higher than plasma TVs and LCD TVs, there is no significant difference in retinal photobiological safety measurement data of the three different display screens. Among the three samples, the measurement results of the LED display screen are even better than the other two display screens.
It should be noted that long-term viewing of any display screen may cause permanent damage to human eyes. Therefore, no matter what form of display screen is used, operators must pay attention to eye hygiene, develop good eye habits, and work and rest. Combine, consciously and actively protect your eyesight.
