Eyesafe Safety Certification issued by LG 65-inch OLED panel. According to our measurements, this panel emits only 34% of the "harmful" blue light in the entire blue range of radiation. In this measure, LG's panel was the best of any OLED TV panel and twice as good as LCD panels.

The Eyesafe standard was developed by this American standardization agency in conjunction with the German technical testing and certification service TUV Rheinland AG. According to the standard, the fraction of the highest-frequency blue radiation in the blue range, which is considered to cause the most significant impact on vision, should not exceed 50%.

They mean this peak of original led light (all else is mostly due to phosphor on top), such is thing for good led backlight

It is not harmful, it is just nasty and makes colors weird.

Btw CCFL due to narrow peaks and large inertia are much better for cheap and accurate monitors backlight, but companies are idiots.
