OLED Screen Burn-In: Causes and Prevention

What burn-in actually is

In an OLED screen, every pixel produces its own light. Like any light source, those pixels gradually get dimmer with use, and they don't all age at the same rate. If one area of the screen shows the same bright image for hundreds of hours, those pixels wear faster than their neighbours.

Eventually the difference becomes visible as a faint outline of whatever was there: the keyboard, a status bar, a navigation button bar or the layout of an app you use constantly. That permanent ghost is burn-in.

LCD screens, such as those in the iPhone 11, iPhone XR and iPhone SE models, use a backlight instead and don't burn in the same way.

Burn-in vs temporary image retention

Not every ghost image is permanent. Image retention is a short-term after-image that fades on its own once the screen shows something else. Here's how to tell them apart:

1. Open a plain, mid-grey image full screen, or a blank page in a grey colour.
2. Turn brightness to around the middle of the slider.
3. Look for outlines, bands or patches that are darker or tinted.
4. If you see one, switch the screen to varied content for a while, then check again.

If the outline fades, it was image retention. If it's still there after a day of normal use, it's burn-in. A grey test image is also the best way to judge how noticeable it is in everyday use.

What causes it

• Static elements: keyboards, status bars, on-screen navigation buttons, game controls and app toolbars that sit in the same place.
• High brightness for long periods: brighter pixels age faster.
• Long screen-on time: drivers using navigation or delivery apps all day, phones used as dashboards and screens that never time out.
• Heat: a phone that runs hot while showing static content, such as on a sunny dashboard, wears the display faster.

How to prevent it

Settings that help

• Keep auto-brightness on and avoid maximum brightness indoors. Apple recommends auto-brightness and Auto-Lock as ways to reduce the chance of burn-in on iPhone.
• Use a short Auto-Lock or screen timeout so the screen turns off when you put the phone down.
• Use gesture navigation on Android instead of the three-button bar, which removes a static element from the bottom of the screen.
• Change your wallpaper occasionally, and avoid wallpapers with sharp, bright, high-contrast shapes in fixed spots.
• Use dark mode where you like it. Darker interfaces light pixels less, which reduces wear.

Built-in protections

Phone makers build in compensation for OLED ageing. Always-on displays, for example, typically shift their clock and icons slightly over time so the same pixels aren't lit constantly. These features run automatically, so you won't usually find a manual "pixel refresh" button on a phone the way you might on an OLED TV.

Habits that help

• For navigation in the car, mount the phone out of direct sun and lower the brightness when you can.
• Don't leave a paused game, video or app on screen with the timeout disabled.
• Avoid apps that claim to "fix" burn-in by flashing colours. They can't restore aged pixels and may simply wear the rest of the screen faster.

Is it something else?

Some screen problems look like burn-in but aren't. Green or pink lines, flickering, black spots that spread or patches that appear suddenly after a drop or pressure point usually point to physical damage to the display, not gradual wear. Our cracked screen guide covers damage-related screen faults.

When burn-in is bad enough to replace the screen

Mild burn-in that you only notice on a grey test screen usually isn't worth fixing. Consider a replacement if:

• You can see the ghost image during normal use, such as on white web pages or in photos.
• It's spoiling video, reading or photo editing for you.
• You're planning to keep the phone for a while, or the screen has other faults too.

Burn-in can't be repaired at the pixel level, so the fix is replacing the display assembly. On iPhones, a technician should explain the replacement screen options for your model, since quality and brightness vary.

When to call a technician

If burn-in or a ghost image has started getting in your way, a certified woman technician from Woman Wireless On The Go can check it in person at your home, workplace or parked car anywhere in our service area and give you a free quote before any work starts.
