What is the main difference between QLED and OLED display technologies?
QLED (Quantum Dot Light Emitting Diode) and OLED (Organic Light Emitting Diode) are two distinct display technologies used in modern televisions and monitors. The primary difference between the two lies in their structure and functionality. QLED displays use a backlight to illuminate a layer of quantum dots, which create the colors on the screen. In contrast, OLED displays do not require a backlight, as each pixel emits its own light when an electric current is passed through it. This fundamental difference affects the overall performance, power consumption, and lifespan of the displays.
The difference in structure also influences the viewing angles, color accuracy, and contrast ratios of QLED and OLED displays. OLED panels tend to offer better contrast ratios and wider viewing angles, as each pixel can be turned on and off independently. QLED displays, on the other hand, rely on the backlight to produce light, which can lead to a lower contrast ratio and slightly narrower viewing angles. However, QLED technology has improved significantly in recent years, and the gap between the two technologies has narrowed. Understanding the differences between QLED and OLED is essential for consumers to make informed decisions when choosing a display for their needs.
Which display technology lasts longer, QLED or OLED?

Burn-in occurs when a static image is displayed on the screen for an extended period, causing the pixels to degrade and creating a permanent ghostly impression. However, most modern OLED displays come with features like pixel shifting and image retention compensation to mitigate these issues. QLED displays, on the other hand, are less susceptible to burn-in and image retention due to their different structure.
Despite the potential for burn-in, OLED displays have made significant strides in recent years, and their lifespan has improved considerably. Many manufacturers now offer guarantees against burn-in and image retention, providing consumers with peace of mind. QLED displays, while less prone to burn-in, can still suffer from backlight degradation over time, which can affect their brightness and color accuracy. Ultimately, the lifespan of both QLED and OLED displays depends on various factors, including usage patterns, settings, and maintenance. With proper care and maintenance, both technologies can provide years of reliable service and excellent performance.
