Have you been listening to these terms alot lately?
Have you been thinking of buying a latest smartphone and coming across these terms which you’re not very sure how do they make a difference?
So to start with these are nothing but the screen refresh rates for the new phones. The refresh rates were not a very look-to feature a couple of years ago but with new savvies around us now it matters alot.
So what is refresh rate?
Displays aren’t static. Content and motion appears smooth on your phone’s screen because every pixel updates to display the latest content from your handset’s processor. But this doesn’t happen randomly. Panels update their content at regular intervals, known as the refresh rate.
The refresh rate measures how quickly the phone’s display updates. In other words, how often and quickly the content on the screen refreshes. Measured in Hertz (Hz), the refresh rate counts the number of times the display refreshes every second it is on. A 60Hz display refreshes 60 times per second, 90Hz is 90 times per second, and 120Hz is 120 times per second. So a 120Hz display refreshes twice as fast as a 60Hz panel, and 4x faster than an old 30Hz TV.
In order for a display to produce the illusion that there’s a moving image in front of you, it has to refresh a certain number of times.
As with any video, what it’s actually showing you is a sequence of still shots, but played consecutively, very quickly. A display refresh rate is simply the rate at which it refreshes to show you that next still shot.
This is the first part of the refresh rate phenomenon and in the second part would be dealing with how does a higher refresh rate makes a difference and is a higher refresh rate always better?
