What Is Screen Burn-In (and Do LCDs Get It?)
Burn-in is a persistent ghost of a static image left on screen. OLED screens are the famous case, but modern LCDs can show a cousin of it too — and the prevention advice for both is different.
OLED: real burn-in
OLED pixels age individually with use. Show the same static elements — taskbars, news tickers, HUD elements — for thousands of hours and the aged pixels fall behind their neighbors, leaving a ghost. It is cumulative wear, not a glitch: no video can undo it. Mitigation is prevention — screensavers, auto-hiding taskbars, pixel shift, and pixel refresh cycles the display runs itself.
LCD: image retention and persistence
Traditional LCDs "burn in" only after extreme static abuse (think airport departure boards); the effect is usually temporary image retention that fades after hours of varied content. Modern LCDs with aggressive pixel-overdrive can also show short retention after long static sessions — leaving the display on a varied full-screen slideshow overnight usually clears it.
How to check what you have
Open our dead pixel test on pure white and pure grey. A ghost of a previous image on any color = burn-in or retention. Then run a full-screen slideshow of varied colors for an hour: retention fades, burn-in does not.
The practical prevention list
Auto-hide the taskbar; dark mode with dark backgrounds on OLED; enable the built-in pixel refresh (OLED care) features; screensaver after 5 minutes on always-on displays; and rotate dashboards and kiosks periodically. None of this hurts — all of it extends the years before the ghost appears.
Frequently asked questions
Can burn-in be reversed?
On OLED, not truly — pixel refresh redistributes wear but cannot restore aged pixels. On LCD retention, yes — it fades with varied content.
Do phones burn in?
AMOLED phones do, eventually — status bar and keyboard ghosts are the classic case. Years of varied use make it a slow, minor issue for most owners.
