SEOUL,
South Korea, July 21,
2024 /PRNewswire/ -- LG Display, the world's leading
innovator of display technologies, announced today that its OLED TV
panels have been confirmed to be excellent for helping viewers
maintain healthy sleep patterns.
LG Display's OLED TV panels proven to 'Sleep Friendly'
supporting body and eye health
The company recently completed a clinical study to verify the
impact of TV panels on sleep, in conjunction with researchers from
Seoul's Kookmin
University. During the two-week study, they measured levels of
the sleep-inducing hormone melatonin in 40 adult men and women
divided into groups watching the same content on either LCD or OLED
TVs.
While the LCD TV group's melatonin secretion fell 2.7% over two
hours, it increased 8.1% in the OLED TV group.
The human body needs melatonin to rise in the evening to prepare
for sleep. However, blue light emitted from displays is
known to disturb melatonin secretion, potentially leading to sleep
disorders.
In general, LCD panels emit 70-80% blue light due to their
continuous reliance on a strong backlight, compared with just 36%
blue light from LG Display's self-emissive, and therefore
backlight-less, OLED TV panels.
"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," said Prof. Kim Chang-wook, who led the research team.
The results of the study confirm previous recognition of LG
Display's OLED panels as supportive of eye and body health,
including being optimized to protect viewers' circadian rhythms.
Last year, the company's OLED TV and monitor panels were the first
in the industry to be certified as "Circadian Friendly" by TÜV
Rheinland, a leading global independent testing, inspection and
certification body.
Moreover, with the lowest level of blue light emissions among
all existing TV panels and absence of screen flicker, a phenomenon
that can cause vision loss, the company's OLED TV panels have
earned the "Eyesafe" certification created by U.S.-based Eyesafe in
association with TÜV Rheinland, along with "Flicker Free" and
"Discomfort Glare Free" verifications from UL, a leading global
safety science company.
"We will introduce products and technologies that can provide
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.
