As most of us talk about the screen’s resolution, colors, PPI, and type, the display refresh rate is never considered as a priority. Well, that has now changed and high refresh rate screens are now in demand.
Let’s talk about what’s refresh rate and how much of a practical impact it makes at the user end.
The term refresh rate, in layman terms, is the count of how many times the screen refreshes its image in one second. It is basically measured in Hz. At present, most smartphone displays have 60Hz refresh rate, or in other words, even if you are viewing a static image, your display is redrawing the same picture or is pushing the same frame 60 times every second.
At times people tend to get confused between higher refresh rates and higher frame rates (Hz vs FPS). FPS is the count of how many frames are being pushed to the display every second. FPS is related to the content you run on the screen, which might be a video or a game.
So, ideally, if your video has been shot and packaged at 90 frames per second (FPS) and your display has a 90Hz refresh rate, your phone will be able to push all frames.
Similarly, you can play games or videos at 90fps on 90Hz refresh rate panel but not on a display with a lower, say 60Hz, refresh rate.
If you feed 60fps content to a 90Hz screen, the display will either switch to 60Hz or duplicate some frames.
The impact is subtle yet noticeable and, we’d say, quite addictive. If you are scrolling in App drawer, in your browser, settings menu, or your social media feed, your content will flow up and down smoothly with less friction. Kind of like the difference you’d feel between pushing an ice slab and a wooden slab on a marble floor. Similarly, animations are smoother too.

Not much content is available to take advantage of 90Hz, so most videos and games push only 60 frames per second. This is also why most high refresh rate phones are programmed to dial down to 60Hz refresh rate when you are watching videos.
Touch Refresh Rate means the speed at which the screen can register your touch and respond by starting to render the next frame in an animation.
If the touch refresh rate and the display refresh rate are both clocked at 60Hz, it means the tracking and refreshing coincide, and the animations are rendered one interval later.
However, say, if the touch refresh rate is 120Hz and the display refresh rate is 60Hz, animations will still be snappier and smoother, and your screen would still appear to be more responsive, but the overall experience won’t match the fluidity of having a 120Hz refresh rate screen.
