LG Display's OLED TV Panels Proven to Promote Healthy Sleep Patterns

LG Display, the leading innovator in display technologies globally, has announced that its OLED TV panels are confirmed to support healthy sleep patterns. The announcement comes following a recent clinical study conducted with researchers from Seoul's Kookmin University, aimed at understanding the impact of TV panels on sleep.

The two-week study involved 40 adult participants, equally divided into two groups. Each group watched the same content on either LCD or OLED TVs. The researchers measured the levels of melatonin, a sleep-inducing hormone, in the participants. The findings were significant: while the melatonin levels in the LCD TV group dropped by 2.7% over two hours, the levels in the OLED TV group increased by 8.1%.

Melatonin plays a crucial role in preparing the body for sleep by rising in the evening. However, blue light emitted from screens can disrupt melatonin secretion, potentially causing sleep disorders. LCD panels, which rely heavily on backlighting, emit 70-80% blue light. In contrast, LG Display’s OLED panels, which ...
... are self-emissive and do not require backlighting, emit only 36% blue light.

Prof. Kim Chang-wook, who led the research team, stated, "In addition to minimizing the negative impact on melatonin secretion during viewing time, OLED TVs have been shown to be effective in maintaining viewers' healthy sleep patterns through greater activation of their parasympathetic nerves, which are responsible for feelings of comfort."

This study reinforces previous acknowledgments of LG Display's OLED panels' benefits for eye and body health. Last year, the company's OLED TV and monitor panels became the first in the industry to be certified as "Circadian Friendly" by TÜV Rheinland, a global independent testing, inspection, and certification body. This certification recognized the panels' optimization for protecting viewers' circadian rhythms.

Furthermore, LG Display’s OLED panels have the lowest level of blue light emissions among all existing TV panels and do not exhibit screen flicker, a phenomenon that can cause vision loss. Consequently, the OLED TV panels have earned multiple certifications: "Eyesafe," created by U.S.-based Eyesafe in collaboration with TÜV Rheinland, as well as "Flicker Free" and "Discomfort Glare Free" verifications from UL, a leading global safety science company.

"We are committed to introducing products and technologies that deliver differentiated customer value based on OLED panels that are safe for the human body while offering the best image quality," said Soo-young Yoon, CTO and Executive Vice President at LG Display.
