As you browse social media late at night or check your emails in dim lighting, screen flicker might be the furthest thing from your thoughts. Yet, for certain Pixel users, this slight flicker can become a significant issue. It stems from a display technology known as PWM (pulse-width modulation), which is commonly used to adjust the brightness on OLED screens.

While most individuals don't notice it, a specific group of users, particularly at lower brightness settings, may experience eye strain, headaches, and even migraines. Despite ongoing feedback over the years, Google has remained silent on the matter—until now.

In a recent comment to Android Central, Google has finally recognized the issue, indicating that their teams are "aware and investigating" possible solutions, with updates anticipated later this year. This marks the first time Google has openly addressed PWM concerns, and with the Pixel 10 on the horizon, the timing couldn't be more opportune.

Google's Initial Acknowledgment of Display Flicker

Let's face it—display dimming technology doesn't usually make headlines at product launches. You'll hear about megapixels, AI features, and battery life, but not so much about how the screen dims.

That's what makes Google's statement noteworthy. As reported by Nicholas Sutrich at Android Central, this is the first time in years that Google has acknowledged concerns about PWM dimming, following persistent inquiries and previous silence.

So, why now? It could be due to timing, pressure, or perhaps Google is finally recognizing that screen comfort is more important than just display specifications, especially as users spend more time on their phones.

What Is PWM Dimming and Why Is It Important?

If PWM is new to you, let's explain it simply. PWM, or "pulse-width modulation," is a method used by OLED displays to control brightness. Instead of reducing the voltage to dim the screen (as with older LCDs), PWM rapidly turns the screen on and off—hundreds of times per second—to mimic lower brightness levels.

For most people, this flicker goes unnoticed. However, for some, especially at low brightness, the brain can detect this subtle flashing, resulting in fatigue, eye strain, or even migraines.

The crucial element here is the PWM frequency—the speed at which the flickering occurs. Devices like the recently released Pixel 9a operate at frequencies around 240Hz or 480Hz, which may not be high enough to prevent noticeable flicker for everyone. In comparison, the OnePlus 13 and 13R use a much higher 2160Hz, which is fast enough that most people don't notice it.

In simple terms, the higher the flicker frequency, the less likely your eyes are to feel it. Google's decision to maintain a 240Hz frequency on its Pixel series has been puzzling, especially when many competitors have already advanced.

What Might Google Do with the Pixel 10?

There's no confirmation yet that the Pixel 10 will address this issue, but Google's statement timing—"later this year"—aligns well with the Pixel 10 launch. Here's what a potential fix might entail:

1. Increased PWM Frequency

The most straightforward and effective solution would be to increase the PWM frequency to 1920Hz or higher. This would align the Pixel with competitors and significantly enhance comfort for users sensitive to flicker.

2. Flicker-Reduction Accessibility Option

Some manufacturers have already included flicker-reduction settings in their OLED display options. Google could introduce a toggle in the Accessibility menu, allowing users to prioritize eye comfort over pure display quality.

3. Software-Based Solutions for Older Pixels

While hardware constraints may exist, Google could potentially release a basic flicker-reduction setting through software updates. This would demonstrate a genuine commitment to resolving the issue, not just for new customers but for existing users as well.

Even If You're Not Sensitive, This Issue Still Matters

Here's the point—not everyone is sensitive to PWM flicker. But for those who are, it's a real problem that can make using a phone genuinely uncomfortable. Eye strain, headaches, and even nausea aren't just theoretical; they're real daily challenges for some users.

Even if you've never experienced screen-induced strain, this is about user choice and accessibility. It's akin to other accessibility options: you might not need it, but someone else might. Given the amount of screen time we accumulate daily, even those without sensitivity could benefit from a screen that's gentler on the eyes.

That's why this development is so significant. Google may be catching up, but it's the kind of change that will genuinely enhance daily usability for many people.

Want More Pixel 10 Insights?

The display might finally be more comfortable on the eyes, but that's not the only change. Google is also making significant strides with the camera setup on the Pixel 10, including adding a telephoto lens to the base model for the first time. However, it's not all positive news.
