What is the difference between Screen Refresh Rate Vs Touch Sampling Rate?

Last Updated on



Our smartphones are getting equipped with new technologies day by day. Every now and then a new feature is getting highlighted or new high-end upgrades are getting featured. One of these latest trends is associated with upgrade Screen refresh rate and touch sampling rate.

What is Screen Refresh Rate and how it differs from Touch Sampling Rate

The latest Asus Rog II featured a 240Hz display, and it resurfaced this war between smartphone brands to provide higher Refresh rates. Suddenly this feature started getting importance over other important ones and it is making people confused. We will today tell you what is Screen Refresh Rate and Touch Sampling Rate and will also discuss different types of Screen rates. We will also discuss the advantages and disadvantages of Higher Screen Rate and will see whether this latest trend is really that much important or not.

Screen Refresh Rate vs Touch Sampling Rate

Screen Refresh Rate

A screen Refresh rate of any display, be it on smartphone, TV, Laptops, etc. is nothing but a count of their content refreshing in one second. It means that the number of times the pixels of the display refreshes in each second or in other words ‘How quickly the display updates itself’. It is as simple as that. Displays of our devices are not static, they show new content in every new frame and hence need to be updated regularly to load the new content quickly.

So, from here the frequencies 60Hz, 90Hz, 120Hz, etc. came. These frequencies simply show the refresh rate like 60Hz means that the display refreshes itself 60 times in a second, 120Hz means that it would be refreshed 120 times in a second.



A question would be arising in your mind about ‘why these all different kinds of refresh rates?’ As you all know the technology is upgrading day by day and it applies here too, new trends demand more frequent refresh rates. High refresh rates result in a smooth motion like a 90Hz display would feel smoother than a 60Hz. If you are a gaming maniac, then higher refresh rates like 120Hz and 240Hz would be better options for you than the lower ones.

Touch Sampling Rate

Now let’s talk about another term Touch Sampling Rate, it is related to the Refresh rate but kind of different also. In simple words, a Touch Sampling Rate is a frequency of a screen to register a touch by the user. It means that how many numbers of times in a second the screen will look for touch input. It is also measured in Hz like 60Hz, 90Hz.

A 60Hz touch sampling rate means that the display will look for the user’s touch input only 60 times in a second, i.e. every 16.6ms your display would be ready to take input. For the 90Hz sampling rate display, after every 11.1ms the smartphone will look for touch input.

So, it is evident that a high touch sampling rate would end up in fast response time as it fastens the input taking capabilities of a smartphone and a phone with a low touch sampling rate will take more time to sense the tap by the user and will result in a delayed response.

Conclusion

So as we have studied about both terms, we can say that the Screen Refresh rate is responsible for the overall smoothness during navigation in a smartphone, and the sampling rate is the frequency of a phone to register the user’s touch in a second.



The question which arises is whether these things really matter much or not. We will say that it depends on the user. An average user won’t notice changes for Refresh rates as the standard 60Hz is enough for them to smoothly navigate through basic apps, but a gaming enthusiast will see a noticeable difference in the quality of gaming in higher sampling rates and higher touch sampling rate.

Keeping it in mind only Asus ROG II, which is a gaming phone, is equipped with a 240Hz display, it would be a treat to play games on this phone. Apart from the advantages, the other side is that these features require a powerful CPU and GPU, and also it drains the battery quickly as compared to the lower frequencies settings.

At last, we would say that these two metrics are important but should not be the only criteria to draw towards a particular smartphone. Check all the features, and complete reviews of the device and then decide. Thank You!
