Harmful blue light, which appears between the wavelengths of about 415
and 455 nanometers, has been linked to eye health. Now, as confirmed by
TÜV Rheinland the percentage of blue light being emitted by the eagerly
anticipated Galaxy Fold has been lowered to 7 percent, a threshold
thought to be unattainable before this year. The percentage of
blue-light emission is 12 percent for existing OLED panels and 18
percent for LCDs.

With eye protection filters and programs now hitting the market as more
consumers learn the dangers of short-wavelength blue light, most have
failed to maintain the display panel’s color gamut. However, Samsung
Display has succeeded in substantially lowering blue light emission
while fully meeting the DCI-P3 optical color standard, by improving the
performance of organic materials in its Galaxy Fold OLED display.

“In a market where technical innovation is materializing at a remarkable
pace, OLED is setting the pace for change in smartphone design as these
foldable, full screen displays prove,” said Jeeho Baek, executive vice
president, Samsung Display mobile display sales & marketing team. “We
are enabling enhanced resolution, while considerably improving the user
environment by minimizing concern for the user’s eyes,” he added.

Besides having the display of the Galaxy Fold certified for Eye Comfort,
Samsung Display recently received a similar certification from TÜV
Rheinland for the flexible OLED panel of the Galaxy S10.
