OLED Burn-In: Causes, Prevention, and How to Check

OLED delivers perfect blacks, but static content can wear pixels unevenly and leave a permanent ghost ("burn-in").

What causes it

Each OLED sub-pixel ages as it's used. Elements that stay on screen for hundreds of hours — taskbars, channel logos, game HUDs — wear faster, leaving a faint outline.

The mechanism is straightforward: an OLED pixel makes its own light from an organic emitter, and that emitter dims slowly with every hour it's driven. Two pixels that have lived different lives no longer match at the same input signal. The blue emitter degrades fastest of the three, which is why worn areas often read as a warm or yellowish patch rather than simply a dim one.

Three factors decide how fast this happens:

• Brightness. Wear scales steeply with drive current. A panel run at maximum brightness ages far faster than the same panel at a comfortable indoor level.
• Time on one image. Static beats bright. A dim taskbar for eight hours a day does more damage than a bright movie for two.
• Color. Large areas of saturated blue or white push the blue emitter hardest.

Panel type matters too. WOLED televisions add a white sub-pixel and drive the color filters less hard; QD-OLED uses quantum dots to convert blue light. Both approaches are far more resistant than early OLEDs, and both still wear. Mini-LED vs OLED covers the choice if you're weighing this risk before buying, and IPS vs VA vs TN vs OLED puts it next to the LCD alternatives.

How to check

Run the Color Test and step through solid colors, then view a 50% gray field via the Brightness Uniformity Test. Burn-in shows as a faint outline of logos or bars where static content used to be — gray makes it easiest to see.

Work through more than one grey level. A mid grey exposes most wear, but a darker grey field and a dim full white each reveal different amounts, so step through a ramp with the Greyscale Test rather than judging from a single slide. Do it in a dark room, from directly in front, with any dynamic brightness or picture-optimizer mode switched off — those features can mask exactly the difference you're hunting.

What you're looking for is a shape you recognize: the outline of a taskbar along the bottom, a rectangle where a channel logo sat, the ammo counter from a game you played for a season. Random blotches without a recognizable edge are more likely panel uniformity or dirty-screen effect than burn-in.

A Black Level Test is worth running alongside, because on OLED it separates two things that look similar: uneven wear shows on bright fields, while near-black performance stays essentially perfect even on a worn panel.

How to prevent it

• Lower brightness for static content.
• Enable pixel shift, screen savers, and logo dimming — our screensaver works for this if the panel has none built in.
• Hide the taskbar/dock; auto-hide menu bars.
• Vary content; don't leave a paused game or news ticker on for hours.
• Run the panel's built-in pixel refresh/compensation cycle.
• Use dark mode in apps you keep open all day, and set a short display-sleep timeout — a screen that turns itself off after ten idle minutes is the cheapest protection there is.
• On a desktop OLED, move the taskbar to auto-hide and avoid a fixed bright wallpaper behind icons in the same spot every day.

About those refresh cycles: most sets run a short compensation pass automatically when you power down after several hours of use, which is why you shouldn't pull the plug the instant the picture goes off. A longer, more thorough cycle is usually offered manually in the settings menu and takes considerably longer. Use the long one sparingly — it's a maintenance tool, not a daily habit.

Check the warranty terms before you buy, too. Burn-in was historically excluded as "normal wear," but several manufacturers now cover it explicitly for a limited period. That clause is worth reading in full rather than assuming either way.

Burn-in vs temporary retention

Run the Burn-in Test to make faint retention visible: a full-screen solid color exposes outlines you would never notice in normal use. Brief image retention fades on its own after varied content. Burn-in is permanent. If an outline persists across many different images, it's burn-in — modern panels resist it far better than early OLEDs, but managing static elements still matters.

The practical test is time. Play varied full-screen video for an hour or two, or run the panel's compensation cycle, then check the same grey field again. Retention will have faded or vanished. Burn-in will be exactly where you left it.

If it is burn-in, nothing you run will remove it — the emitters are worn, not stuck. What you can do is stop it getting worse: drop brightness, kill the static elements that caused it, and get the compensation cycle running regularly. Photograph the grey field now so you have a dated reference to compare against in six months, and check your warranty terms while the evidence is fresh.
