Did you know? OLED burn-in is permanent and irreversible, yet over 40% of buyers don't know how to test for it when purchasing used OLED displays. This guide will teach you everything about burn-in detection, prevention, and what to look for when buying OLED technology.
OLED (Organic Light-Emitting Diode) technology offers stunning picture quality with perfect blacks, infinite contrast ratios, and vibrant colors. However, this superior display technology comes with a unique vulnerability: burn-in. Understanding burn-in is crucial whether you're buying your first OLED display, maintaining one you own, or shopping for used OLED monitors and TVs.
What is OLED Burn-in?
OLED burn-in, also known as image retention or ghosting, occurs when static images displayed for extended periods cause permanent discoloration or "ghost images" on the screen. Unlike temporary image retention that fades after displaying different content, burn-in is permanent damage to the organic compounds that produce light in OLED pixels.
Burn-in vs Image Retention
Temporary Image Retention
- • Fades after minutes or hours
- • Caused by pixel voltage differences
- • Reversible with pixel refresh
- • Normal OLED behavior
Permanent Burn-in
- • Never fades or improves
- • Caused by organic material degradation
- • Irreversible damage
- • Requires panel replacement
⚠️ Important Distinction:
Many people confuse temporary image retention with burn-in. True burn-in is visible on all content and doesn't improve over time. If ghost images disappear after displaying different content for a while, it's retention, not burn-in.
How and Why Burn-in Occurs
To understand burn-in prevention and detection, it's essential to understand the science behind it. OLED pixels contain organic compounds that emit light when electrical current passes through them. These organic materials degrade over time, and this degradation accelerates with use.
The Science of Pixel Degradation
Key Factors in OLED Degradation:
- 1. Cumulative Usage: Each pixel degrades based on total light output over its lifetime. Pixels displaying bright content degrade faster.
- 2. Uneven Wear: Static elements cause some pixels to degrade faster than others, creating visible differences.
- 3. Color-Specific Degradation: Blue subpixels degrade fastest, followed by green, then red. This causes color shifts over time.
- 4. Heat Acceleration: Higher temperatures accelerate organic material breakdown, making cooling important.

High-Risk Usage Patterns
Certain usage patterns dramatically increase burn-in risk. Understanding these helps both in preventing burn-in on your displays and identifying high-risk units when buying used.
🚨 Highest Risk Activities:
News Channels
Constant logos, tickers, and banners create perfect conditions for burn-in. CNN, Fox News, and financial channels are notorious.
Gaming HUDs
Static UI elements like health bars, minimaps, and scoreboards in games cause focused burn-in patterns.
PC Desktop Use
Taskbars, desktop icons, and window borders create predictable burn-in patterns when used as monitors.
Security Cameras
Static camera feeds with UI overlays cause severe burn-in, often rendering displays unusable.
Risk Assessment by Usage Type
Movies & Streaming
Low RiskDynamic content with minimal static elements. Black bars on movies pose minor risk.
Sports
Medium RiskScore displays and channel logos can burn in with extended viewing.
Console Gaming
High RiskStatic HUD elements in long gaming sessions create focused burn-in areas.
PC Monitor Use
Very High RiskStatic UI elements make standard PC use extremely high risk for OLED.
How to Test for Burn-in
Thorough burn-in testing is crucial when buying used OLED displays. Here's a comprehensive testing methodology that will reveal even subtle burn-in:
