I have been reading about this burn in issue from quite a few days since the discussion started here. And here are my discoveries:
Advantages of LCD Screen:
- Better display for color (most realistic).
- Better brightness (helpful outdoors)
-
Very rare burn in issues if any.
Advantages of Amoled display:
- Better black color, since pixels that needs to show black are turned off thereby also saving battery.
- Bright colors pop more while dark scenes (since AMOLED screens produce a deeper black and a better range of greys). Translates to better Multimedia experience.
Disadvantage of LCD Screen:
- Brightness falls drastically if screen is viewed at off angle. The colors are good but the display gets much darker.
- Individual pixels can't be turned off. Translates to more battery consumption.
Disadvantages of Amoled display:
- A little yellowish display. Nothing much but if you compare it along side of a LCD screen, you
Will notice the difference.
- Strange black bars (but
very faint) mostly perceivable only in light shades of color like white and Grey
- Screen Burn In issue.
Now it all comes down to the preference of user for choosing LCD over Amoled or vice versa. But this Screen burn in issue of Amoled displays is a thing which seems to be the biggest issue and that I really want to focus on, since its something that still reminds people of the old CRT monitors which use to show them.
I had a phone which had LCD and I used it for 3 years (LG P500). And I am using Amoled on my Moto X. I would any day prefer Amoled display. 1st and 2nd disadvantage of Amoled is of little concern to me. Contrary to that, I believe display of Amoled is more night friendly with regards that it can produce better dark. A little toned down white makes for a display that doesn't hurt your eyes when reading in night. So, my only concern was the "Burn In".
Well, nothing can be done from your part that makes your Amoled phone totally vaccinated against Burn in but one can only take precautions that they never happen in the first place. To list precautions we have to understand the areas which can cause Burn Ins. Two most obvious areas can be seen:
1. Navigation Bar
2. On screen buttons (the Back, Menu and Recent Apps button).
Nothing much can be done to avoid those except hiding the notification bar on homescreen using launcher such as "Apex". So the only thing which we can really take care are following:
1. Not keeping the phone's display ON while charging (which can be done from settings).
2. Not allowing the screen to keep a static picture for long (that is to swap keyboard layout from black background and white text to White background and black display etc).
But really only these things have to be taken care of, and you can enjoy the advantage of Amoled displays without worrying about Burn In issue.
The most clear advantage of Amoled display is the feature such as Active Display which allows you to view notifications right on lock screen without turning on the entire display. I guess that is the single most advantage of Amoled display over LCD with regards to the fact that unlike LCD screens, user do not need to turn on the screen every-time they need to check for notification. This saves battery AS WELL AS avoiding any chance of burn in issue. Also, you can keep a wallpaper black (or closer to dark shades) which would ALSO save battery since the black pixels would be turned off anyway.
So in the end, advantages of Amoled displays far outweighs the disadvantages IF, and that's a BIG IF, user is willing to take care of points discussed to avoid keeping a static image on screen for much time.
And as they say for Amoled displays,
"Once you go deep black you never go back."
