Recent research from the Pacific Northwest National Laboratory (PNNL) highlights the negative health impacts associated with LED lighting, particularly in devices like smartphones that utilize Pulse Width Modulation (PWM) dimming. This study indicates that many modern LED displays are contributing to eye strain, headaches, and other health issues due to low flicker frequencies. Current offerings from major smartphone manufacturers, such as Apple and Samsung, often operate at a flicker frequency below the recommended 2400Hz, which is necessary to reduce these adverse effects. Alternative solutions, like DC dimming, championed by brands such as OnePlus and Motorola, have shown considerably lower annoyance ratings and fewer health complaints. As LED technology becomes ubiquitous, PNNL emphasizes the need for manufacturers to prioritize user health in their designs, prompting consumers to consider alternatives that better mitigate these adverse effects.
