OLED Burn-in Test - Detect Screen Burn & Image Retention
A proactive maintenance tool designated for OLED, AMOLED, and Plasma displays. "Burn-in" is permanent physical damage to pixels that have unequal wear. This tool helps you: 1) Detect existing burn-in using a full-screen Grey/Red field, and 2) Prevent future burn-in by "scrubbing" the screen with a rapidly changing pattern to exercise static pixels.
🔥 Image Retention vs Permanent Burn-in
Image Retention (Temporary)
Ghost images that fade away after displaying different content for a while. This is normal on some displays and usually clears itself. Not a defect.
Burn-in (Permanent)
Permanent ghost images that remain visible indefinitely. Caused by uneven pixel wear from displaying static content for extended periods. Requires panel replacement.
⚠️ Common Burn-in Sources
- • TV channel logos (news tickers, network bugs)
- • Operating system taskbars and dock
- • Game HUD elements (health bars, minimaps)
- • Application UI elements (sidebars, toolbars)

How to Use Color Palette & Display Tester
Detection Phase
Run the test. Watch the gray field. Look for shadows of: • TikTok/YouTube UI icons. • News tickers (CNN/BBC bottom bars). • Battery/Wifi status icons (on phones). If you see a faint shadow that doesn't go away, you have burn-in.
Conditioning Phase
Leave the "Noise" or "Color Cycle" pattern running for 1 hour. This can help "unstuck" temporary image retention (which looks like burn-in but isn't permanent).
Calculator Features
Pixel Refresher
High-speed noise pattern forces every sub-pixel to alternate states, potentially clearing "Image Retention".
Sub-Pixel Inspection
Solid color fields (Red/Grey) are best for revealing specific organic material degradation.
Warranty Validator
Use this test to document "Cumulative Wear" before your warranty expires.

Common Calculations & Examples
Example 1: Buying a Display Model TV?
Problem: Store display TVs run the same demo loop for 7000 hours.
Steps:
- Ask to test the TV.
- Run the "Red Screen" (part of this suite).
- Look at the center.
- If you see a shadow of the "Sony/Samsung" logo, WALK AWAY. That panel is trash.
Explanation: Red light is often the first to fail on OLEDs. A burn-in shadow is irreversible.
