Key Takeaways
1. Chinese smartphone brands like Xiaomi and OnePlus use high PWM frequencies over 2,000 Hz to eliminate visible flickering in AMOLED screens.
2. The Google Pixel 9 has a noticeable PWM frequency of 120 Hz, causing discomfort for some users, while the Pixel 9 Pro’s display flickers at 240 Hz.
3. The flicker amplitude on the Pixel 9 is 22.2%, which can lead to severe headaches for sensitive users.
4. Google plans to address flickering issues in upcoming updates and potentially improve the PWM frequency in future models.
5. The upcoming Pixel 10 series may feature displays with higher PWM frequencies or DC dimming to reduce flickering, though it could affect peak brightness.
Chinese smartphone brands like Xiaomi and OnePlus are leaning towards very high PWM frequencies that go beyond 2,000 Hz. This helps to stop visible flickering in their AMOLED screens. On the other hand, users of the Google Pixel 9 (around $599 on Amazon) still have to deal with a more noticeable PWM frequency of 120 Hz. Our tests also showed that the Pixel 9 Pro’s display flickers at a slightly elevated 240 Hz.
Flickering Issues
This flickering can cause discomfort, particularly in the lower-priced Pixel 9 model, which has a flicker amplitude of 22.2%. Those who are sensitive to such issues may suffer from severe headaches after looking at screens with PWM flickers for long periods, while others might not even notice it. Google has recognized this problem and mentioned to AndroidCentral that users can look forward to updates later this year.
Potential Solutions
It remains uncertain if Google can enhance the PWM frequency on current Pixel phones via a software update. Nonetheless, the company’s announcement hints that the upcoming Pixel 10 series could come with displays that have less flickering. By using higher PWM frequencies or DC dimming, Google might be able to lessen or completely remove flickers. Another option could be a special display mode designed to minimize screen flickers, but this may result in lower peak brightness on some devices. All in all, these changes indicate that the Pixel 10 series may finally address the concerns of users who are sensitive to PWM flickering.
