"imprinted" the game logo on the screen... How is this possible?

Question

Mobile devices

Why did this happen and how to fix it? Smart - Xiaomi Mi9. I use 8 months. Recently I began to notice lines on a bright screen. I thought that it was the "insides" of the screen that became visible, or what was under it. But a couple of days ago I noticed that the game logo appeared. Immediately realized that these lines are from the lobby of the game. How could this happen? When I played, I always played at maximum settings, the screen brightness was full, plus I added brightness and saturation with the Game Turbo application.

All these lines and the logo are slightly visible with a bright screen on a white (light) background.

Answer 1

The screen of this phone is made using SuperAMOLED technology
. Among the disadvantages of this technology:

a decrease in service life during active work in bright colors, in other words, a gradual “burnout” of organic LEDs. At the same time, subpixels of different colors lose their brightness at different rates (blue ones burn out the fastest), which can cause the color reproduction of the screen to be disturbed over time. The display life of an average mobile phone is approximately 7 years, but after a year, differences in the brightness of the areas are noticeable.

The blue subpixels are less bright, so more current is applied to them to maintain color balance than the red and green subpixels. Because of this, the life of the blue diodes is reduced, over time they shine more and more dimmer, and the color reproduction of the screen goes into red and green shades.
Burn-in occurs where blue or white is heavily used. Black color does not use pixel backlighting, so it does not cause burn-in. Burnt pixels become dark and visible on the screen. The brighter the image, the better they can be seen.

When I played, I always played at maximum settings, the screen brightness was full, plus I added brightness and saturation with the Game Turbo application.

well, well done...
