OLED Pixel Wear and Static Image Retention

OLED screens can produce deep blacks and strong contrast because each pixel generates its own light. A black pixel can simply remain off instead of relying on a shared backlight. That same self-emissive design also gives each light-producing element a finite operating life. As an OLED panel accumulates use, its subpixels gradually lose some ability to produce the same brightness from the same electrical drive. Normal aging is spread across the panel when content changes frequently. Static logos, status bars, game interfaces, navigation controls, or other fixed graphics can concentrate use in particular areas. If the difference becomes large enough, a faint trace of those shapes can remain visible during unrelated content.
