LG Display has added to its string of awards and certifications, saying that its OLED TV models have become the first in the world to earn the Eyesafe Circadian Certification that reaffirms its technology’s unique benefits in terms of eye health and promoting better sleep.
Eyesafe is a U.S. organisation that specialises in blue light mitigation technologies, and it’s focused on enhancing the human circadian rhythm, which repeats every 24 hours. This rhythm is important because it regulates the production of key hormones including Melatonin, which helps to induce tiredness, and critically, can be disrupted by late-night exposure to TV screens.
To measure the impact of blue light – the major source of this disruption – Eyesafe has developed what it calls the Circadian Protection Factor, which is a novel index that assesses the amount of blue light emitted by TV displays and estimates the impact on melatonin secretion.
In its tests, Eyesafe found that LG Display’s OLED TV and monitor panels achieved the highest CPF rating, emitting just 36% blue light, the lowest of any display type in the industry.
Some TV experts say that blue light is needed in displays because it helps to prevent the distortion of on-screen colours, but LG display argues that its self-emissive OLED panels are able to maintain excellent colour reproduction, despite cutting out most of the harmful blue light emissions.
As a result of the latest certification, Eyesafe’s Vision Health Advisory Board, which is made up of a number of renowned global ophthalmologists and optometrists, has endorsed LG Display’s OLED displays as an “excellent choice” for those who demand excellent image quality with minimal impact on their sleep patterns, the company said.
The certification comes shortly after LG Display and Kookmin University in South Korea concluded a clinical trial that demonstrated how subjects watching TVs using Mini-LED panels suffered a 2.7% decrease in melatonin secretion, compared to an 8.1% increase among those who only watched OLED-based TVs.
The award is just the latest in a long line of certifications received by LG Display, which has often cited the health benefits of its OLED TVs as an added advantage for consumers. Earlier awards include the Flicker Free certification from UL Solutions. It has also won a number of rewards testifying to the eco-friendly nature of its TVs.
Hyeon-woo Leo, head of the Large Display Business Unit at LG Display, said the award demonstrates once more how the company provides “differentiated value with human-friendly OLED” that not only delivers quality pictures, but also improves the health of its users.
