Why keyboards create repeated wear
Typing areas place repeated bright keys and interface shapes in the same lower-screen region over long periods of time.
That repeated pattern can contribute to uneven aging compared with less active parts of the panel.
How to inspect lower-screen retention
Use black and gray patterns and pay close attention to the lower third of the display where keyboards usually appear.
If you see a block-like shape or repeated key-area shadow, compare it across several patterns for confirmation.
How serious keyboard burn-in is
Faint lower-screen retention may not always matter, but obvious shapes can remain visible in apps and fullscreen content.
Because the lower display is used often, repeated visible wear can become distracting over time.
FAQ
Can keyboards really cause OLED burn-in?
Yes. Repeated typing layouts can contribute to uneven wear in the lower screen area over time.
Which pattern is best for keyboard burn-in checks?
Black and gray are good first choices for seeing lower-screen ghosting or retention.
Should I inspect the lower third of the screen closely?
Yes. That is the area where keyboard-related wear usually becomes visible first.
