How does LED and OLED light affect sleep?

In a new study, researchers explored the effects that different types of light exposure during the evening have on a person’s metabolism during sleep.

The research, which appears in the journal Scientific Reports, offers further evidence for the negative effects that blue light exposure in the evening can have on an individual’s health.

However, organic light-emitting diodes (OLEDs) produce less blue light than LEDs. OLED technology is becoming increasingly popular in the screens of the latest phones, computers, and televisions.

Because OLED produces less blue light than LED, it could be that the negative health effects associated with LED screen exposure are not as significant in OLED displays.
