Display PWM Dimming Comparison: Samsung Galaxy S23 Ultra Vs Apple and Honor flagships

Smartphones are rapidly becoming smart and smart, thanks to technological innovations. In a recent development, a display PWM dimming comparison surfaced on the internet revealing that the Samsung Galaxy S23 Ultra is way too behind in this aspect against Honor.

Twitter user TECHINFO45 shared a video displaying the screen flickering on three flagship phones. In the video, Honor was the star of the show, leaving Samsung Galaxy S23 Ultra and Apple iPhone 14 Pro in the dust, when it comes to display PWM dimming.

Higher display PWM dimming frequency of Honor 90 Pro made it a clear winner over the world’s two most powerful smartphones. FYI, PWM is a technique for controlling the brightness of a display panel by varying the width of the light pulse. You control how long the screen remains on or off.

PWM dimming frequencies:

1. Honor 90 Pro 3840Hz
2. Galaxy S23 Ultra – 240Hz
3. Apple iPhone 14 Pro – 480Hz

Lowering the brightness causes the screen to be off for longer than it is on, which is perceived as lower brightness. The higher frequencies the lower rate of stress on human eyes that’s what studies say but it doesn’t mean Samsung panels are not eye-friendly.

It’s worth mentioning that some smartphone users may find them sensitive to the display flicker effects, while some aren’t. Here’s the smartphone equipped with a display having a higher PWM dimming frequency that would do a lot better, thanks to the low rate of flickering on the panel.
