Refresh Rate - definition
Refresh rate defines the number of times in a second a display is updating the. The more the refresh rate is the smoother the motion becomes. In other words, it can be said, refresh rate is a term that defines the vertical scanning rate every second.
In computer or mobile phone displays we’ve seen multiple refresh rates such as 60Hz, 75Hz, 120 Hz, 144 Hz, and 240 Hz. The standard setting is 60 Hz for a screen because in this range the screen can’t penetrate the eyesight as the human eye is unable to catch that speed. But if the refresh rate is lower than 60, then you’ll notice the flickering on the screen (i.e.: feels like a horizontal black thick border is moving or display is turning off and on million times) and after a few moments, it’ll start penetrating your eyes.
That is why people who used to stay in front of the computer the whole day long like gamers, server operators, production operators, or similar always suggest using a refresh rate at least equal to or more than 75 Hz so that it can’t hamper the eyesight or a very few amounts.
Experiment: Take two phones supporting two (2) different refresh rates which are: 60 Hz and 120 Hz. Now if you start using both phones at the same time you’ll notice the screen movement looks much more alive and smoother in the 120 Hz display than the 60 Hz one.
