Some sources claim that you can fix screen burn-in, but unfortunately this information is not truthful.
As much as I would like to offer you a quick fix for this issue, I must explain that this problem is permanent. Simply because those pixels where exposed to very unfavorable conditions for longer that they could remain undamaged. And when screen burn-in occurs, it means that permanent damage is already inflicted on those pixels and they lost their ability to relay color information accurately.
Some sources claim that you can fix screen burn-in by displaying a certain solid image or color on your screen. This method should be as effective, as fixing a broken light-bulb by not turning the lights on for a day or two.
Moreover, a screen panel is a passive device and it cannot comprehend whether the final result (the image formed on screen) is accurate or not. Also, a screen has millions of individual pixels and only a certain percentage is usually affected by burn-in. This is what makes a burn-in visible in a first place – a non uniform image which indicates that not all pixels are acting the same when they should.
Which means that even if you could fix individual pixels by exposing them to the opposite conditions from those that caused the problem, it would not be possible to inflict this reversal effect on each individual pixel accurately. As individual pixels would have individual level of damage, and thus would require individual exposure to “healing” conditions.
Icon, keyboard, time or other home screen widget burn-in is quite common among smartphones. Here are just a few burn-ins that are not going away, unfortunately:
I know this could be hard to comprehend, but the bottom line is – there is no reversal from screen burn in. Which is why it is very important to follow the user guide recommendations when we use monitors, smartphones, laptops, tablets, TVs and other screens.
