Hello there qurantine crew! This is yours truly bringing you yet another tech instalment from lockdown! π

Refresh rates compared.
Before I get to what LTPO is, let me run you through what refresh and frame rates are.
To begin with, frame rates and refresh rates aren't the same thing.
The refresh rate is a hardware capability whereas the frame yet is the maximum refresh rate a particular app / game can support.
Not that confusing eh? Quite refreshing. π
Can you stop making unnecessary puns Dhruv?
Of course. I Hertz you.
You see, every display out there has a capped / locked fresh rate.
My S9+ is capped at the conventional 60Hz. This means that the display on my device refreshes 60 times a second. To correlate this on other electrical devices, let's take a light bulb for example. In India, appliances are set to run at 50Hz. This implies that these appliances "refresh" 50 times a second. You can't notice it with your naked eyes.
Pro tip : Open up your camera and point it at the light bulb / any tubelight. Now dial back your exposure and notice your bulb pulsate (obviously not at 50 times/s but you get my point).
Why does it refresh like that? Well, that's because the current alternates 50 times a second. That is why it's called AC or alternating current. You're welcome. ππ₯
Okay enough of bulbs and tubelights, let's get to the point.
Back to screens. 2020 has seen the trend of high refresh display panels on smartphones. The Galaxy S20 lineup of phones have displays that can run at 60Hz / 120Hz. Along with a high refresh rate of 120Hz they also have a high touch response of 240Hz. In simple terms, touch response is the time between you touching your screen and the device reacting to it. Naturally, a higher response sensitivity will mean that time will be lesser, and hence more responsive.
However, this means that the display can alternate between 2 refresh rates - 60 and 120Hz. But what about the refresh rates in between?
This is where LTPO tech comes into play.
LTPO stands for Low Temperature Polycrystalline Oxide.
This technology allows for a truly variable refresh rate on the display, instead of it being able to switch between only two options.
The Note 20+ is tipped to feature this technology and if it does, will be the first line of Galaxy devices to ever feature this piece of tech.
So that was it for refresh rates and LTPO technology.
As always, thank you for your time reading this.
Take care, stay safe and most importantly, stay home.
This is Dhruv Jain signing off until next time. π―
Thank you. π
