Apple's iPhone X Screen Is Giving Some Users Headaches
by PATRICK SEITZ, investors.com, 14 November 2017
AAPL) iPhone X customers have reported eye fatigue and headaches from using the new premium handset and are taking to online forums to share their concerns.
"Ever since Thursday I have been experiencing headaches every time I'm on my phone for around 10 minutes-plus," one iPhone X user said in a MacRumors forum on Saturday. "This has never happened to me before on any of my other devices."
Another iPhone X user replied, "Same thing, got really sore eyes since two days (really painful), the X is the culprit for sure. I don't know what to do."
Some tech-savvy forum members on MacRumors suggested that the eye strain is the result of Apple's use of pulse-width modulation to dim the brightness of the OLED display. They noted that some people are more sensitive to the flicker effect than others.
The number of iPhone X owners complaining about the display issue is hard to quantify at this point.
One user in Los Angeles told IBD that he experienced eye strain from the iPhone X and decided to trade the device in for an iPhone 8 Plus, which has an LCD screen. The user said he didn't know if it was the OLED display technology itself that was giving his eyes problems or the lack of a display zoom option in combination with the narrower screen width on the iPhone X.
Apple did not respond to a request for comment by the time this article was posted.
Apple shares were down 1.5% to close at 171.34 on the stock market today.
New iPhone designs like the iPhone X tend to have more technical issues than established form factors.
On Friday, MacRumors reported that a limited but increasing number of iPhone X owners have encountered a green line appearing on the smartphone's display.
On Sunday, 9to5Mac reported that some iPhone X users are experiencing crackling and buzzingsounds from the handset's earpiece speaker.
