TÜV Rheinland is a prominent German independent inspection service company, and UL is a leading global safety certification firm.
LG Display’s OLED offerings are now tagged as “Eye Comfort Display” and “Flicker Free Display”—which mean they boast low blue-light levels and more fluid and smoother performance.
According to LG, this is the first time that TV displays have received such certifications. The OLED TV panels receiving these distinctions range from 48 to 88 inches.
When tested by TÜV Rheinland, LG’s OLED displays were discovered to produce 0% non-visible flickers—as OLED’s individual pixels are known to emit light on their own, jettisoning the need for backlighting found on LCD-based panels.
UL, meanwhile, issued a “Flicker Free Display” verified mark of 1.3%, which is significantly below the standard of 9.6%. LCD-based sets are known to flicker as they emit light, which can sometimes cause headaches, eye fatigue and diminished vision upon prolonged exposure.
LG’s OLEDs are certified by TÜV Rheinland for emitting the lowest possible levels of blue light. They were also able to attain the highest blue-light safety rating by UL—which is 50% lower than the standard set forth by the International Electrotechnical Commission.
Studies have shown that blue light can penetrate all the way to the retina in the back of the eye and build up over time. The cumulative effect causes disruptions in sleep patterns, eye strain, dry eyes and unnecessary exhaustion.
LG Display said it would encourage its global distributors to use the “Flicker Free” and “Low Blue Light” certification marks when marketing the company’s OLED TV offerings.
“As people have more time to watch TV at home during the COVID-19 pandemic, eye comfort is becoming a more important factor to consider,” Dr. Chang-ho Oh, senior vice president and head of the TV business unit at LG Display, said in a release.
“LG Display will continuously offer the best experience to its customers through its OLED displays providing maximum eye comfort as well as unparalleled picture quality and futuristic design.”
