What is the main difference between OLED and QLED TVs?
The main difference between OLED and QLED TVs lies in their panel technology. OLED (Organic Light-Emitting Diode) TVs use an emissive technology, where each pixel emits its own light, resulting in true blacks and infinite contrast ratio. On the other hand, QLED (Quantum Dot Light Emitting Diode) TVs use a transmissive technology, where a backlight is used to illuminate a layer of quantum dots, which create the colors.
This difference in technology affects the overall picture quality, with OLED TVs generally offering better contrast, deeper blacks, and a wider viewing angle. However, QLED TVs have their own strengths, such as higher brightness and a longer lifespan.
Which TV technology is better for gaming?
When it comes to gaming, OLED TVs are generally considered the better option. This is because they offer faster response times, lower input lag, and a wider viewing angle, making them ideal for fast-paced games. Additionally, OLED TVs can display true blacks, which can enhance the overall gaming experience.
However, QLED TVs are not far behind, and some high-end QLED models can offer similar gaming performance to OLED TVs. Ultimately, the choice between OLED and QLED for gaming depends on individual preferences and the specific TV model.
Do OLED TVs suffer from burn-in?
One of the concerns with OLED TVs is the risk of burn-in, which occurs when static images are displayed for an extended period, causing permanent damage to the panel. However, most modern OLED TVs have features to mitigate burn-in, such as pixel shifting and image retention compensation.
