Google has teased that upcoming Pixel devices, likely starting with the Google Pixel 10, will feature significant improvements in display technology. A key enhancement being explored is the Pulse Width Modulation (PWM) dimming rate, which has been a point of concern for users, especially those sensitive to screen flicker. PWM dimming controls the brightness of an OLED display by rapidly turning the screen on and off, making it appear dimmer to the human eye. While this is an effective method for controlling brightness, the rapid flickering can cause discomfort, eye strain, or even sickness for some users, especially at lower dimming rates.
Historically, Google’s Pixel devices have had relatively low PWM dimming rates, with the Pixel 8 Pro, for example, offering a rate of just 246Hz. In comparison, competitors like Honor and Samsung have already implemented much higher rates, with Honor’s budget-friendly Honor 200 Pro boasting a 3840Hz rate, and Samsung’s Galaxy S24 series featuring a 492Hz PWM rate. Google’s announcement suggests the company is addressing this issue and will likely debut improvements starting with the Pixel 10.
What PWM Dimming Means for Users?
For those unfamiliar with the technicalities of display technology, PWM dimming is crucial for managing how a screen adjusts its brightness, and it plays a significant role in user comfort. At lower dimming rates, the frequency of flickering becomes more noticeable, leading to potential eye strain, headaches, and discomfort, particularly when users are looking at their screens for extended periods. As the PWM rate increases, the flickering becomes less noticeable, reducing the risk of discomfort.
In recent years, many phone manufacturers have focused on improving PWM rates to provide a more comfortable experience for users. Brands like Honor have led the charge, offering extremely high PWM rates. Samsung has also improved its dimming technology with a 492Hz rate on its latest flagships. However, Google has lagged behind in this area, and the Pixel 8 Pro’s 246Hz rate has drawn criticism for not being as smooth as some of its competitors.
Expectations for google Pixel 10 Series
Google’s announcement hints that future Pixel devices, particularly the Pixel 10, will bring improvements to PWM dimming rates. The company acknowledged that it is aware of user concerns about PWM sensitivity and has been investigating ways to address these issues. While specific details were not provided, Google teased that “updates later this year” will tackle this problem, with expectations that the Google Pixel 10 will introduce a much-improved PWM dimming rate.
While software solutions to mitigate the effects of PWM flicker are possible, hardware upgrades are the most effective way to achieve a noticeable improvement. It remains unclear whether Google plans to implement a hardware change or if it will rely on software settings, as seen with Motorola’s previous approach. Further details will likely emerge as the google Pixel 10 series nears its expected release around August. Users eager for a smoother display experience will likely have to wait until then for more definitive information on how Google plans to tackle the issue.
