It is understandable why the producers started switching to them.

OLED displays are not so much hurt the eyes like LCD screens in modern devices. They emit significantly less “dangerous” blue light, allowing you to preserve the eyesight of users. This is evidenced by research scientists Taiwan University NTHU.

In the comparative test involved smartphones iPhone XS Max and the iPhone 7. The tests were conducted on two patented techniques that have been developed by scientists. The first method involves the assessment of maximum permissible exposure, showing how quickly “burns” the retina in contact with the radiation screen. The second method estimates the maximum damage from blue light emitted by the OLED and IPS displays.

When exposed to radiation at 100 LX retina iPhone XS Max “survived” 346 seconds. For the owner of the iPhone 7, the procedure could become “fatal” in 288 seconds. This suggests that the iPhone screen XS Max almost a third of the safer display of the iPhone 7.

Similar results were demonstrated in the situation with a “bad” blue light. If you take 100% perfectly pure blue light, 6.5-inch iPhone XS Max sensitivity to suppression of melatonin is in the range of 20.1%. The iPhone 7 is the ability to “protect” from blue light much weaker is 24.6%. All of this suggests that the iPhone screen XS Max protects eyes from harmful blue light than the display of the iPhone 7.

The results of the test clearly show that smartphones with OLED and IPS matrices differently affect the eye the same perception of users. “Color temperature” IPS screen is much higher OLED-display that directly adversely affects the vision of the owner of the device.
