Burn-in and image retention: what is the difference?
Both burn-in and image retention leave a faint copy of something that was on screen, often a taskbar, a channel logo, or a game HUD. The difference is whether it goes away. Image retention fades after the screen shows other content for a while. Burn-in is permanent, because the panel itself has aged unevenly.
Why OLED panels burn in
Every OLED subpixel produces its own light, and the organic material that produces it slowly loses efficiency the more it is driven. If one area shows the same bright static element for hundreds or thousands of hours, those subpixels age faster than their neighbors. The worn area then becomes slightly dimmer, and you see the shape as a ghost on uniform backgrounds.
The blue emitters have historically aged fastest, so burn-in often shows up as a color tint, not only as a darker area. Current panel designs try to reduce this. LG’s WOLED panels add a white subpixel, and Samsung Display’s QD-OLED panels use blue emitters with quantum-dot color conversion. Both still need care with static content.
Image retention on LCDs
LCDs do not have burn-in in the OLED sense, because the backlight ages evenly. They can show temporary image retention, especially IPS panels after a high-contrast static image stays up for a long time. Charge builds up in the liquid crystal layer and holds the old pattern faintly. This usually clears after minutes to hours of changing content or after the display is turned off for a while.
How to check, and how to tell which one you have
- Look at uniform full-screen colors. A 20–50% gray, solid red, green, and blue, and white each reveal different worn subpixels.
- Lower the room light, but keep the screen at your usual brightness. Very high brightness can hide subtle differences.
- If you see a shape, play varied full-screen content for an hour or two, or leave the display off on standby, then check again.
- If the shape fades, it was image retention. If it stays the same after several days and after the panel’s compensation cycle, it is burn-in.
Reducing the risk
Modern OLED monitors and TVs run a short compensation routine when they go into standby. This is often called pixel refresh, panel care, or panel maintenance. Leaving the display powered at the wall lets it run. Most also offer pixel shift, which moves the image by a few pixels, and logo or static-area dimming, which lowers the brightness of elements that do not change.
On the computer side, you can auto-hide the taskbar or dock, use dark themes, enable a screen saver or short sleep timer, and avoid keeping a game HUD or a fixed window at maximum brightness for hours. Several OLED monitor makers now include burn-in in their warranty. The length and conditions vary, so check the terms for your model.
Common questions
- Should I run the manual pixel refresh often?
- No. The full manual refresh evens out wear by slightly using up the panel’s remaining brightness headroom. Manufacturers usually advise running it only when you actually see retention that the automatic short cycles did not clear.
- Can burn-in be removed?
- True burn-in cannot be reversed, because the affected subpixels have physically aged. Compensation routines can sometimes make it less visible by adjusting the drive levels of neighboring areas.
- Does a new OLED with a faint shape out of the box have burn-in?
- Often not. A factory test pattern or a display unit left on in a store can leave retention that clears after the first few compensation cycles. Note what you see, use the screen normally for a few days, and check again before you decide.
