Let's talk about a major display issue that's been overlooked by Samsung, despite being a simple fix for years. It's a problem that affects a significant portion of the global population and can cause serious discomfort and even trigger health issues. I'm referring to the PWM dimming rate on smartphone displays, and how Samsung's Galaxy S26 Ultra, despite its innovative Privacy Display feature, continues to fall short in this area.
The PWM Dimming Dilemma
Pulse Width Modulation (PWM) dimming is a common method used to control display brightness. However, at lower frequencies, it can cause flickering, leading to eyestrain, headaches, and nausea for those sensitive to it. This is a real issue, and one that many smartphone manufacturers have already addressed with high-frequency PWM dimming or alternative solutions.
Samsung's Missed Opportunity
Samsung, a leading smartphone brand, has failed to implement basic display and software changes to mitigate this problem. The Galaxy S26 Ultra, for instance, still operates at a low 480Hz PWM rate. This is especially disappointing when you consider that even budget Android phones like the HONOR X9d offer a much higher PWM dimming rate of 3,840Hz. Samsung could have easily increased its frequency to above 1,000Hz, a level associated with fewer negative effects, without incurring significant costs.
Accessibility and Transparency
What's more, Samsung doesn't provide users with many options to address this issue. There's no higher PWM dimming frequency, no DC dimming options, and no flicker reduction settings. Other brands, like Xiaomi and OnePlus, have implemented DC-like dimming or software features to reduce flickering. These features are essential for those with photophobia or conditions like chronic migraines, where flickering can trigger attacks and worsen pain.
A Niche Concern?
Some might argue that PWM sensitivity affects only a small minority, but this is a shortsighted view. Photophobia, or sensitivity to light, affects a vast majority of people with migraines, and migraines affect over a billion people worldwide. This is not a niche concern, and manufacturers should be more transparent about their display features and specs to allow consumers to make informed choices.
A Call for Action
As the world's biggest Android smartphone company, Samsung should be leading the way in display accessibility. While the Privacy Display is a nice addition, it's a gimmick without these essential accessibility features. It's time for Samsung to step up and provide users with the options they need to protect their eye health. After all, our smartphones are the screens we interact with the most, and they should not be a source of discomfort or health issues.
Conclusion
The PWM dimming issue is a clear example of how small changes can make a big difference in user experience and accessibility. It's time for Samsung and other manufacturers to prioritize these features and be more transparent about their display specifications. Until then, users will continue to suffer, and that's a problem that needs to be addressed.
