 What is screen burn in

You probably have read the debates on which screen type is best for you. And for those on the IPS side,the one thing they can use to trump the AMOLED guys is the issue of screen burn in. But what exactly is screen burn in?I'll try to explain in this post.

You may never have experienced screen burn in,but Pixel 2(and Pixel 2 XL) users will tell the tale.Screen burn in was a major problem of the Pixel 2(and Pixel 2 XL) ,and despite it's software patches to try and alleviate the problem,those that have their screens permanently burnt in will have to live with it,as there is no cure for screen burn in.

So,what is screen burn in?

When you first hear the term,'burn in',you'd probably think it involves actual burning of the screen.But no,it doesn't.Burn in is actually the term used to describe the situation in which a display suffers a permanent discoloration across any part of the screen's panel.But this doesn't just happen for text. It occurs for pictures,colors or the navigation bar(which is on screen in this case).And this is an exclusive property of all OLED displays . The displaystill functions normally,but there is a permanent discoloration that persists as long as the display is on. 

What does burn in look like

Typically,a screen suffering from burn in looks like this:

The term 'burn in' was actually first used in old CRT monitors,where the phosphor coating emitted light which produced images  which lost their luminance with time.And although today's OLED panels burn in is not as bad as the older CRT issues,it's a closely related problem.And this problem can be very,very obvious or very difficult to notice.And,it takes a lot of time for this problem to manifest.

What causes screen burn in

For this section of the post,I'm going to divide this category into two parts:

-The normal explanation

-the technical explanation

-The normal explanation

Screen burn in usually occurs when the same image is displayed on an OLED screen for a very,very long time.And when the image is changed or removed,an outline of the image which appears 'burnt in' is formed.

-The technical explanation

Burn in is caused by the varying lifecycle of the pixels beneath an OLED display. As some parts age faster than the others,their brightness changes,and the panel's color reproduction shifts with time. But burn in is a faster degradation of some parts of a display more than the others,while color reproduction changes occur uniformly across the panel.

How to prevent screen burn in 

If your screen is already affected by burn in,there's not much you can do to solve it.There are some apps on Google's Play Store that claim to fix this issue,but they just end up burning the rest of the screen to match with the burnt area,which isn't the best solution.

But if you haven't been affected by this problem,here's 5 quick ways to prevent it

1. Keep your brightness low: except when it is really,really needed to crank your brightness above 30%,always keep it at 30% or less indoors to actively prevent burn in.

2. Hide your navigation bar when not in use or switch to navigation gestures. There are certain apps on the Play Store that can enable iPhone X like navigations on your phone if you don't want to use the navigation bar. Of course,this only holds to phones with on-screen navigation buttons.

3.Pick a wallpaper that is completely black or has a dark theme.This not only prevents screen burn in,but can also increase battery life.

4. Lastly,don't use any fancy keyboards with bright colors,especially if you chat for long periods of time. This prevents color degradation and prevents burn in in the lower part of the display.

Is burn in still a problem

In this day and age,burn in is no longer a problem as today's manufacturers produce OLED screens that have a much longer lifespan than before. And provided you follow all these suggestions,your OLED screen should be fine.(unless of course you own a Pixel 2,in which case you have to buy a new phone. Her's a guide on how to do that.)
