November 3 on the Apple site appeared background information on the new screen iPhone X, working on AMOLED technology. It states that the new smartphone can sometimes have a burnout effect, but the display is designed to reduce the likelihood of this factor.
With very long use, OLED screens can receive minor visual changes. This is an expected phenomenon that can include “burnout” and “afterglow” when the remainder of the previous image is only slightly visible on the screen even after a new one has appeared. This can occur in more extreme cases, for example, when a high-contrast image has been shown for a long time.
In order to reduce burn-out, the company recommends setting the auto-turn off of the display to the minimum timer (30 seconds of inactivity), and if you need to continuously display static images on the screen, you should lower the screen brightness.
Unlike previous models, which used liquid crystal displays IPS LCD, in iPhone X pixels of the screen glow independently and their brightness directly affects the power consumption. At the presentation of the iPhone X, the company emphasized the improvement of image quality thanks to AMOLED technology, but did not speak about its shortcomings.
For AMOLED screens, the burnout effect is typical: if any element of the interface is constantly in the same place with high screen brightness, the pixels on this place get an “imprint”. This happened with Google Pixel 2: according to journalists, its AMOLED-screen began to burn after a week of use, and the company began checking these messages (which it ended, it is unknown).
