LG Display, First in the Industry to Achieve 100% Luminance Maintenance Verification
Samsung Display, Flex Magic Pixel Technology Verified
LG Display and Samsung Display have each objectively proven the strengths they have been highlighting: the superiority of self-emissive technology and the excellence of privacy protection features.
On the 25th, LG Display received performance verification from global certification company UL Solutions, confirming the excellence of its large OLED panels by certifying that all of its large OLED panel products achieve a "100% luminance (screen brightness) maintenance rate." The luminance maintenance rate is a percentage-based measure of how well a display can reproduce content based on its brightness. LG Display’s OLED panels maintained their brightness performance even when the test reference area was reduced, thereby achieving a 100% luminance maintenance rate. In contrast, LCD-type panels became darker as the test reference area decreased, with the luminance maintenance rate dropping to between a maximum of 83% and a minimum of 43%.
LG Display plans to further strengthen its leadership in large OLEDs based on this world-class OLED technology. The company’s new large OLED TV panel products achieve a peak luminance of 4,500 nits (nit, the brightness of a single candle), and are also equipped with technology that absorbs and diffuses light instead of reflecting it, resulting in the lowest reflection rate among existing displays, at 0.3%.
Lee Hyunwoo, Head of the Large Display Business Unit at LG Display, said, "We have objectively identified why OLED appears brighter and clearer," adding, "Through objective verification, we can now explain more clearly to customers that OLED’s pixel dimming technology, which maintains a 100% luminance maintenance rate, is the best choice in the AI era."
On the same day, Samsung Display’s smartphone OLED featuring the next-generation privacy protection technology "Flex Magic Pixel" (FMP) passed UL Solutions’ "Privacy Display" verification. FMP is a panel-integrated privacy protection technology that makes the screen appear clear from the front, but blurry or almost invisible from the side.
UL Solutions stated, "Assuming the front screen brightness of Samsung Display’s smartphone OLED is 100, the brightness at a 45-degree side angle dropped to 3.5%, and at 60 degrees it fell to 0.9% or less," confirming that it provides viewing-angle blocking performance in all directions, including up, down, left, and right.
Samsung Display plans to showcase its premium OLED technology "LEAD 2.0™," which integrates its FMP technology, at "MWC26," the world’s largest mobile exhibition, set to open on March 2 (local time) in Barcelona, Spain.
Lee Hojung, Vice President and Head of Product Planning Team in the Small and Medium Display Business Unit at Samsung Display, said, "LEAD 2.0™ is an innovative technology that maximizes security performance through all-direction viewing-angle blocking, while also improving power efficiency, which is the biggest challenge in the on-device AI era," adding, "We will continue to devote ourselves to developing new technologies to enhance convenience for smartphone users."
