Easy on the Eyes: How the Galaxy S10’s Display Protects Users from Blue Light
6/14/2019
If you’re usually on your phone before bed and you find yourself having trouble falling asleep, you’re not alone.
According to recent findings from Counterpoint Research, nearly half of all global smartphone users spend more than five hours a day on their mobile device. Once the sun goes down, studies show that the blue light from your smartphone’s screen and other artificial light sources can throw your biological clock out of whack – making it harder to fall asleep and potentially causing more serious problems down the line.
To safeguard users’ eyes from the harmful effects of blue light, Samsung equipped the Galaxy S10 line with a display that reduces exposure to blue light wavelengths – without compromising picture quality. Let’s take a closer look at how blue light affects our eyes, and how the Galaxy S10’s display protects them.
Why Blue Light Exposure Matters
Blue light is generally defined as a high-intensity, short-wavelength (380 to 500-nanometer) range of light on the visible light spectrum.
These days, whether it’s through our electronic devices’ screens, energy efficient lighting, or simply sunlight, we’re constantly being exposed to blue light. Which isn’t all bad. According to the Royal Society Te Apārangi, a not-for-profit organization based in New Zealand, “Adequate exposure to daylight, particularly during the morning, is important for synchronizing the circadian body clock, which can affect many processes including sleep, metabolism, immune function and even our mood.”
However, when viewed at night, blue light has been shown to suppress the production of melatonin (a hormone that regulates sleep–wake cycles) more powerfully than other types of light, affecting our ability to sleep. Recent research from the University of Toledo also suggests that blue light from mobile devices can cause harm to the eye’s retina.
How Blue Light Affects Sleep
In this digital age, with smartphone users spending increasingly more time on their mobile devices, it’s easy to see why blue-light reducing technology has become absolutely necessary.
How the Galaxy S10 Reduces Blue Light Transmission
The Galaxy S10, Galaxy S10+, Galaxy S10e and Galaxy S10 5G’s Dynamic AMOLED display was built from the ground up to minimize eye strain so users can get a better night’s sleep.
Galaxy S10 users can sleep soundly knowing that their smartphone’s display has been certified by world-renowned testing firm TÜV Rheinland[1] to drastically reduce blue light’s harmful effects. When building the display, which received TÜV Rheinland’s official ‘Eye Comfort’ certification, Samsung applied new organic materials that reduce blue light wavelengths measuring between 415 and 455nm (the range that research[2] suggests is particularly harmful to the retina) by up to 42 percent[3] – without the use of filters.
This significant reduction in blue light transmission is the product of Samsung’s continuous commitment to developing industry-leading AMOLED technology. The Dynamic AMOLED display reduces the transmission of ‘harmful’ blue light (wavelengths in the 415 to 455nm range) to below 7 percent – the industry’s lowest mark. This means that the Galaxy S10’s display reduces 42 percent more blue light than previous AMOLED displays.
The Galaxy S10’s display also produces incredibly lifelike colors. To enable users to enjoy crisp, immersive colors day or night, Samsung went to great lengths to ensure that the display’s blue-light reducing innovations wouldn’t compromise image quality.
