Recent research from the Pacific Northwest National Laboratory highlights the detrimental health impacts of LED lighting, particularly in devices like smartphones. While many manufacturers claim their displays are “flicker-free,” this designation often fails to address harmful flicker rates. Current models from major brands like Apple and Samsung typically operate at a 480Hz pulse width modulation (PWM), which can lead to eye strain and discomfort. In contrast, newer devices utilizing DC dimming or higher PWM rates, such as the Vivo X100 Pro running at 2400Hz, demonstrate significantly less annoyance and health issues. Studies indicate that up to 64% of migraine sufferers report symptoms from current LED technologies, suggesting a pressing need for manufacturers to prioritize health considerations in their design choices. As awareness of these issues grows, consumers are encouraged to consider alternative brands that adopt safer display technologies for their well-being.
