OLED vs LCD displays is apparently one of the biggest debates one might get in. You might reach a point when someone raises the point of screenburn-inn. Screen burn-in is one of the disadvantages of an OLED screen. Well, as you might have guessed it already this article deals with the screenburn-inn. So, let’s get started!
What is screen burn-in?
I’ll have to say that the name “screen burn in” is a bit misleading as this has nothing to with burning or any heat-related issues on the screen. Screen burn-in is nothing but an appearance of a ghostly image on your screen. It might seem similar to Image retention in the LCD displays. The image retention in the LCD is a temporary issue but in case of OLED’s it is likely to be permanent. Don’t you remember the screen burn-in Pixel 2?
The issue arises when a block of a display is constantly producing the same colors whereas the other part of the display is experiencing a consistent change in colors. You might wonder that how can this cause screen burn-in?? Well, let me explain….
The LEDs embedded into the display suffer from phenomena known as aging. Aging is nothing but a slight decrease in the color production capacity of the LEDs. The block of display that is producing the same colors for a long period of time is likely to age faster. The areas that might suffer from this are the navigation bars and the notification panels.
The always on display is also one of the areas where you might experience screen burn in. The reason for aging is the low luminous efficiency of the blue LEDs. The blue LEDs are not as bright as the red and green so, the more current is needed so as to reach the brightness level of the red and green. This decreases the overall life of the blue LEDs. This, in turn, leaves the red and green LEDs at the same brightness. Can you really notice it?
Well, screen burn does not occur until you’ve been using the device for years. It is not noticeable until you know what you are looking for. But, if you notice it then you might end up scratching your head…
Can you avoid Screen burn-in??
Yea, you can but this can only delay the issue. Screen burn-in is something that has to occur and you cannot eradicate it. Smartphone giants like Samsung have come up with a way that can save you from the issue. Basically, what Samsung does is that it shifts the pixels by a very little amount (only the areas producing constant colors). This issue is so serious that even Apple addressed its concern that the iPhone X might get the same problem in future! However, till now, the phone has suffered due to its green superpixels only!
This is an excellent technique as this balances the load on every bulb and aging is delayed for significantly large amount of time. Google’s new materialistic design prevents the aging even further. One way that you can avoid it is by changing the wallpapers of the device constantly say about every 4-5 days. This will prevent the production of same colours on specific areas.
This is all that you need to know related to this topic and I’ll see you later with another issue in my hand!
