LG Display has received official verification of the low blue light emissions of its OLED TV displays from leading global safety certification company, UL.
The ‘Low Blue Light Display’ Verified Mark from UL (originally Underwriters Laboratories Inc) is granted to display products when their blue light emission meets the “risk exempt” standard (100W/sr/m2) set by the International Electrotechnical Commission (IEC).
During testing, LG Display’s OLED TV panels were found to emit 50 percent lower blue light than the standard, or about 60 percent of blue light that the same-size premium LCD TV displays on the market are reported to emit.
However, the verification raises a few questions. Last year LG Display were awarded ‘Eye Comfort’ certification for low blue light parameters in its OLED TV displays by TUV Rheinland, a similar inspection and certification outfit and it's not clear why LG Display has moved from TUV to UL in just 12 months.
Dr. Chang-Ho Oh, Executive Vice President & Head of the TV Business Unit at LG Display was in charge of putting the company’s OLED panels though both certification programmes.
It’s also not clear whether the UL validation is only relevant to the latest 2020 range of OLED panels or if it supersedes the TUV certification across all recent OLED ranges. It’s possible the UL badge is more well known as a mark of safety than TUV in the US market where several TV manufacturers plan to release OLED models for the first time.
While the details of the testing and the rationale for the change in the testing partner remain unknown, the bottom line is that LG Display’s OLED panels have certifiably lower blue light emissions which will result in reduced eye fatigue and sleep disturbance for viewers.
Given increasing awareness among consumers about the effects of overexposure to screens that emit too much blue light and the rise in ‘Dark Modes’ on devices such as mobile phones to help ease strain on the eyes, LG Display expects that the UL Verified Mark will further underscore the value of OLED TVs to consumers. Since 2020 will be a year that sees new LG Display clients such as Sharp, Vizio and Skyworth all releasing OLED TVs, the company will encourage its global OLED TV brands and distributors to use the Mark.
Dr. Chang-Ho Oh said, “This UL Verified Mark makes it clear that LG Display’s OLED TV displays exceed the highest international standards with regard to eye safety. These OLED displays are already touted for their unmatched picture quality and design flexibility in the market, and now we expect that OLED’s recognized value in terms of eye health will further convince consumers to opt for OLED TVs down the road.”
Mirko Bautz, Vice President of Global Accounts at UL, added, “UL empowers trust by helping demonstrate how a brand and its products are responsible and worthy of consumer confidence.” He went on, "As a globally recognized company with deep experience and expertise in the field of test evaluation, we are excited that our methods confirmed that LG Display is delivering on their claims.”
With increasing numbers of OLED TVs predicted to be sold over the next three years (shipments are forecast to grow to 5.4 million units in 2020, increasing to 7.3 million units in 2021 and over 12 million units in 2023), what do AVForums readers think of having the ‘Low Blue Light Display’ badge for TVs?
