Scanning frequency, also known as refresh rate, is a criterion that is of interest to mobile carriers and is expected to become a future trend. So what is the refresh rate on the smartphone screen? What’s the difference between 60Hz, 90Hz, 120Hz? Let’s find out with Tnhelearning.edu.vn right here.
What is the refresh rate (refresh rate)?
Concept
The refresh rate (also known as Refresh Rate) is a measure of how many times the image on the screen is updated per second . It is measured in Hertz (Hz) . In fact, what you see displayed on the phone screen is not a continuously changing animation, but a series of static images projected at a very fast rate, giving your eyes the sensation of as if they were actually in motion.
Meaning
Simply put, a higher refresh rate means less motion blur and significantly clearer image quality , resulting in a smoother viewing experience, while also helping your eyes. more tired when looking too long on the screen. Most smartphones these days are equipped with 60Hz displays.
What’s the difference between 60Hz, 90Hz, and 120Hz refresh rates?
A higher refresh rate makes moving content smoother and cleaner . Although most content like surfing email or Facebook doesn’t make the difference big enough for the average user to notice. However, apps and content with a lot of motion graphics appear like games smoother with higher refresh rates.
In fact, once your monitor has a refresh rate twice as fast, the experience is smoother, while a 60 Hz monitor can seem a bit laggy, especially when you put two 120 Hz monitors. and 60 Hz side by side will see that more clearly.
A 120 Hz screen will consume a large amount of processing power, so it will consume a lot of battery , while a 60 Hz screen will use less power during use, making the battery last longer. Depending on how often you use the screen with a high refresh rate, the battery life also varies.
For example, if we use the 120 Hz refresh rate screen on the ROG Phone 2 for a long time, the machine will last about 6 hours, and with the 90 Hz screen, the machine will last about 7 hours.
When using alternately between the 90 Hz and 120 Hz screens on ROG Phone 2, we will see that the battery life will not differ too much.
Should you choose a smartphone with a high refresh rate?
If you are a smartphone user to play games and want your experiences to be vivid, fast, smooth, without jerks, lags, and frame breaks , a smartphone that supports 120 Hz screen will be the one. desirable choice.
90Hz and 120Hz screens are increasingly popular in modern smartphones, especially in the high-end market. This feature is also increasingly available in affordable mid-range handsets.
It can be seen that the refresh rate is only a small part of a smartphone’s display specifications . This is definitely not a big enough feature for users to decide to choose a phone.
However, for those of you who love owning a smartphone with a high refresh rate, products such as: Samsung Galaxy S20 5G (120Hz), OnePlus 7T (90Hz), Realme X50 Pro 5G (90Hz), Asus ROG 2 (120Hz) will be suggestions not to be missed.
