LG Display’s ‘Circadian Friendly’ OLED Panels Illuminate the Importance of Restful Nights

Artificial lighting may be an essential part of modern-day society, but its impact on sleep quality cannot be overlooked. As many individuals suffer from chronic sleep disorders, it’s about time we acknowledge the negative effects of artificial light on our health. These days, simply using a smartphone, TV, computer, or other digital screens in the evening can disrupt our body’s natural circadian rhythm. This is why experts recommend that you retire your displays one or two hours before bedtime to restore your body’s natural sleep cycle.

As the pioneer of the industry, LG Display has responded to this call for safer displays with outstanding OLED TV and monitor panels that have been certified by the global authority on safety and quality testing, TÜV Rheinland. Notably, LG Display became the first display company to achieve the ‘Circadian Friendly’ Certification, underscoring its commitment to ensuring its cutting-edge display technology has as little impact on sleep as possible. Let’s uncover exactly what this certification entails and explore the exceptional human-friendly technology that sets LG Display OLED apart.

Circadian rhythm, the timekeeper in charge of your health and sleep

Ever wondered what a ‘circadian rhythm’ is? It’s the patterns of various physiological processes in the human body that repeat roughly every 24 hours. Our bodies are synchronized by the Suprachiasmatic Nucleus (SCN), a region nestled within our brain, which takes charge of regulating this rhythm. Picture the stress hormone cortisol kicking in from around 6 am to 8 am to energize us for the day ahead, and the sleep hormone, melatonin, taking over around 9 pm to lull us into a restful state at the end of the day. It’s a captivating symphony of biological harmony!

LG Display OLED’s unique ability to maximize natural light

LG Display’s OLED TVand monitor panels, which emit light pixel by pixel without a backlight, offer a solution to sleep disruption. Recent tests conducted by TÜV Rheinland on its impact on hormone secretion, specifically melatonin, gave OLED panels the industry’s highest rating, assuring consumers that its impact on their circadian rhythm is minimal.

This evaluation process used the credible “Circadian Stimulus” metric established by the Lighting Research Center at the Rensselaer Polytechnic Institute. As a testament to their exceptional performance, the two panels were granted “Circadian Friendly Level (CFL) 1” certification – the highest level.
