Samsung’s OLED Display on Galaxy Fold Receives International Recognition for Reduction in Eye-impairing Blue Light


Seoul, KOREA — April 17, 2019 — Samsung Display announced today that the display panel on the new Samsung Galaxy Fold smartphone has been awarded an Eye Comfort certification from the internationally recognized TÜV Rheinland, for a sharp drop in the emission of blue light.

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 and head of the Mobile Display Sales & Marketing team at Samsung Display. “We are enabling enhanced resolution, while considerably improving the user environment by minimizing strain on 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.
