OLED (Organic Light-Emitting Diode) computer monitors have made significant strides in recent years, with an array of options available to consumers. LG Display and Samsung Display have introduced competing models, including white OLED (WOLED) and quantum dot OLED (QD-OLED), respectively. As the availability of OLED monitors increases, questions about the long-standing issue of burn-in persist.
Yes, burn-in still happens
If you’ve ever owned a plasma display, you’re likely acquainted with the dreaded phenomenon of burn-in. While some enthusiasts downplay the risk of burn-in, modern OLED monitors are not immune to this issue. Recent stories suggest that burn-in can still occur and remains a concern for monitor owners.
Dough (formerly known as Eve) consulted with gaming monitor brands before launching its OLED monitor and discovered that around 5% of users experienced burn-in after two years. While this figure may be taken with caution, it highlights the fact that burn-in is not entirely obsolete.
Burn-in risk varies from monitor to monitor
The risk of burn-in depends on various factors, including the materials used in the display and the design of the monitor. Advancements in OLED and quantum dot materials, coupled with physical design changes, have contributed to the longevity of OLED displays. Manufacturers implement different firmware, software, and hardware techniques to combat burn-in, making it challenging to determine which OLED monitors are more susceptible to burn-in.
QD-OLED vs. WOLED burn-in
The introduction of QD-OLED technology by Samsung Display brought new choices for consumers. QD-OLED uses red, green, and blue subpixels in a triad formation, while WOLED has four subpixels (white, red, green, and blue). Some early tests suggested that QD-OLED might be more susceptible to burn-in due to the simultaneous operation of all three subpixels to display white. However, ongoing longevity tests have revealed that burn-in concerns were actually related to temporary image retention.
Monitor brand matters
The way OEMs test and implement burn-in mitigation techniques significantly influences the risk of burn-in. It’s essential to trust the vendor’s testing procedures and consider the brand’s track record in terms of quality assurance. Different OEMs may use varying standards and testing methods to address burn-in.
A deeper look at testing
Dell-owned Alienware, for instance, collaborates with panel suppliers to optimize algorithms and fine-tune specifications for testing. Different OEMs employ their own testing standards and methods. Consumers are advised to review warranty terms, as they vary among OLED monitors and may not cover burn-in.
Heat matters, too
Heat management is a crucial factor in preventing burn-in. Higher temperatures can accelerate the degradation rate of OLED pixels, making efficient heat dissipation vital. Some OLED monitors use ventilation, heatsinks, and optimized voltage algorithms to minimize burn-in risk. Investigating the cooling features of an OLED monitor is essential before making a purchase.
How willing are you to use burn-in mitigation techniques?
OLED monitors offer various image retention prevention features, including compensation cycles and pixel shifting. These features can be effective but may require user customization. Users should be willing to use these features, such as dark mode, active screen savers, and refresh cycles, to reduce burn-in risk effectively.
Advancements could further reduce burn-in risk
Manufacturers like LG Display and Samsung Display continue to research and develop ways to enhance OLED durability and efficiency. These developments include the use of deuterium, dual-layer OLED designs, and phosphorescent OLED (PHOLED) materials, which have the potential to improve image retention and efficiency.
Conclusion: The Future of OLED Monitors
In summary, the risk of burn-in in modern OLED monitors is not as significant as it once was. Advancements in materials and technology, coupled with testing procedures and image retention prevention features, have made OLED monitors more resistant to burn-in. The choice between QD-OLED and WOLED does not necessarily determine burn-in risk, as other factors play a crucial role.
As the tech industry continues to invest in OLED technology, the future of OLED monitors appears promising. Users who are willing to use burn-in mitigation techniques and carefully choose their monitor can enjoy the benefits of OLED displays with reduced risk. The evolution of OLED technology ensures that burn-in is a consideration but not necessarily a deal-breaker in the quest for high-quality monitors.
