Explained: What is touch sampling rate and how is it different from screen refresh rate

A feature that most smartphone users touch sampling rate look for in their devices before picking one is a display that supports a higher screen refresh rate. However, this new trend of higher screen refresh rate overshadows another important metric: the touch sampling rate. Both features are equally important for users to get the best viewing experience. Here we will discuss how touch sampling rate differs from screen refresh rate and how it is essential for consumers.

What is Touch Sampling Rate?

The touch sampling rate is the number of times a display can refresh itself to register a user’s touch input in one second. For example, if a smartphone has a touch sampling rate of 60Hz, it will look for the user’s touch input only 60 times in a second. That means every 16.6ms; the smartphone will be ready for a touch input from the user.
The smartphone will have to wait for 16.6ms to register a user’s input if it misses recording a touch input in one cycle. For more extensive cycles, the smartphone will take more time to write down the user’s tap, process it, and respond accordingly.

Importance of Touch Sampling Rate

The cycles between these touch inputs get shorter with higher-touch sampling rates, and users have a better chance of registering their touch inputs with higher-touch sampling rates. As it is increased in a display screen, taps start getting instantly recorded and processed.

The screen refresh rate is the number of times the display on a device updates or “refreshes’ itself every second; it updates the current image and creates a sense of motion. It is the number at which a display can render maximum frames in one second. For example, 60Hz refresh rate is a standard for most devices, and it means that the particular show can refresh the screen 60 times in one second.

 

Therefore, more frames will appear in one second if the screen has a higher refresh rate, eventually resulting from smoother smooth motion.

If your smartphone display has a higher refresh rate, users will have smoother motion output while watching animations, scrolling, transitioning among apps, and other UI tasks. Smartphone displays with higher refresh rates don’t skip a single frame and offer a fluid experience for users.

Touch Sampling Rate v/s Screen Refresh Rate

The screen refresh rate adds smoothness to the overall experience during UI navigation, and the touch sampling rate helps get a quicker response to your touch input. Both these metrics are very different and come with other objectives, but they are equally important. If you want to make your smartphone experience more smooth and responsive, opt for a device with both a higher screen refresh rate and a touch sampling rate.
