Safe Non-Invasive Testing
Pure visual-assist detection — no hardware contact, no system settings modified. Built-in 5-minute OLED auto-sleep protection. All processing runs locally in your browser with zero privacy risk.
What Is OLED Burn-In?
Understanding screen retention and pixel aging helps you detect and prevent it more effectively.
Permanent Burn-In
OLED organic emitting materials degrade over time. When static patterns (navigation bars, status bars, channel logos) are displayed continuously, those pixels age faster than surrounding areas, creating permanent "ghost images." This damage is irreversible.
Temporary Image Retention
Unlike burn-in, image retention is temporary. After displaying the same image for extended periods, you may briefly see a "ghost" of the previous image after switching. This usually fades within minutes to hours without causing permanent damage. LCD screens can also exhibit this.
Brightness Non-Uniformity (Mura)
Some OLED panels may have uneven brightness from the factory, commonly called "dirty screen effect." Most visible on low-brightness grey screens as blotchy bright/dark patches. This is a manufacturing variation, not usage wear, and can be quickly identified using this tool's solid color mode.
How to Detect OLED Burn-In
Three-step quick check — no software downloads needed.
Select Test Mode
In fullscreen, use solid color mode to cycle through red, green, blue, white, and grey backgrounds. Burn-in marks are most visible on solid color backgrounds — look for faint text or icon remnants.
Focus on Key Areas
Phone burn-in is common at the top status bar and bottom navigation bar areas. TV burn-in appears at logo and subtitle positions. On grey backgrounds, carefully observe whether these areas have patches brighter or darker than surroundings.
Confirm & Assess
If the same remnant is visible across multiple solid colors at the same position, burn-in is confirmed. Mild burn-in may not be noticeable during normal use; severe burn-in warrants contacting brand support to check warranty coverage.
Four Test Modes Explained
Solid Color Rotation
The most fundamental burn-in detection method. The screen cycles through red, green, blue, white, black, and other solid colors. On a single-color background, any brightness difference caused by pixel aging becomes extremely obvious. Best performed in a dark room.
Sliding Color Bars
Colored bars slide horizontally across the screen at constant speed. Since the bars are moving, any burned-in area produces a noticeable color difference against the sliding bars — easier to spot mild retention than with static solid colors.
Checkerboard Inversion
Black and white checkerboard pattern alternates rapidly. This mode quickly checks pixel response consistency — if some pixels have aged significantly, you'll see obvious "ghosting trails" or brightness inconsistency during black-white switching.
Gradient Sweep
A smooth black-to-white (or color-to-color) gradient slowly moves across the screen. Gradient mode is especially effective for detecting OLED "dirty screen effect" and localized brightness non-uniformity, as any discontinuity in the gradient gets amplified.
Which Devices Are Most Susceptible?
Understanding burn-in risk across different scenarios for targeted prevention.
Phone AMOLED
High-Risk Areas:
• Bottom navigation bar/gesture indicator, especially on older phones with three-button navigation.
• Fixed UI elements of frequently used apps (e.g., social media bottom tab bars).
• Extended outdoor use at maximum brightness accelerates aging.
OLED TV
High-Risk Scenarios:
• Extended viewing of sports or live events with fixed scoreboards and subtitles.
• In-game HUD (health bars, maps, scoreboards) displayed continuously.
• Letterboxed films (top/bottom black bars age differently, causing brightness variance).
OLED Monitor
High-Risk Scenarios:
• Spreadsheet grid lines and toolbars displayed for extended office work.
• IDE/code editor fixed sidebars and line number columns.
• Static webpage headers and sidebar layouts.
Game Console + OLED
High-Risk Scenarios:
• PS5/Xbox persistent in-game HUDs (health, ammo, minimap).
• AFK waiting screens and forgotten pause menus.
• RPG fixed skill bars and status bars.
OLED Burn-In Prevention Guide
Lower Brightness
Keep screen brightness at 50-70%. High brightness significantly accelerates OLED organic material aging. Reducing brightness is the single most effective longevity measure.
Use Dark Mode
Dark mode keeps large pixel areas in low-power states, reducing aging. Dark themes also save battery — especially beneficial for AMOLED phones.
Set Auto-Sleep
Set phone auto-lock to 30 seconds–1 minute. Enable idle auto-off for TVs. Prevent static images from persisting on screen.
Enable Pixel Refresh
Most OLED TVs include a "Pixel Refresher" feature (e.g., LG's Pixel Refresher). Run it periodically per manufacturer recommendation to equalize pixel aging.
Frequently Asked Questions
Q.Can OLED burn-in be repaired?
Minor image retention can self-recover through normal use or running pixel refresh functions. But true physical burn-in is irreversible organic material degradation — no software can fix it. Some "burn-in repair videos" actually accelerate aging in other areas to mask the difference, further damaging the screen.
Q.Can LCD screens get burn-in?
LCD screens very rarely experience traditional "burn-in," but can develop temporary image retention. After displaying static content for extended periods, a brief ghost image may appear after switching, typically fading within minutes to hours. LCD burn-in risk is far lower than OLED.
Q.Should I test a new phone for burn-in?
New phones are unlikely to have burn-in, but it's recommended to check with fullscreen solid colors after initial setup for factory defects — brightness non-uniformity (dirty screen), dead pixels, or color bias. Finding issues early allows timely exchange within the return window.
Q.Does OLED TV warranty cover burn-in?
Varies by brand. Some premium brands (LG, Sony) cover burn-in under certain conditions, but typically require official inspection confirmation. Check warranty terms at purchase, or consider buying extended warranty.
Q.Why test in a dark room?
In bright environments, ambient light reduces the visibility of subtle brightness differences, making mild burn-in and mura patterns harder to spot. After turning off lights, defects become much more apparent on pure black or low-brightness grey backgrounds.
Q.How long does burn-in testing take?
With this tool, 2-5 minutes covers the basic check. Cycle through solid color backgrounds, focusing on burn-in-prone areas (status bar, navigation bar, logo positions). If the same remnant is visible across multiple colors at the same location, burn-in is confirmed.
OLED Screen Care Tips
- • Wallpaper Choice: Use dark or frequently changing dynamic wallpapers. Avoid static wallpapers with high contrast or large pure white areas long-term.
- • Hide Navigation Bar: Enable fullscreen gestures on your phone to hide the bottom navigation bar. Reduces risk from fixed UI elements persisting.
- • Scheduled Shutdown: Set TVs and monitors to auto-off after 4 hours of inactivity to prevent the screen displaying static content unattended.
- • Balanced Usage: Keep usage time balanced across all screen areas — watch fullscreen videos, switch between apps, and avoid one app dominating screen time for too long.
