What is the main difference between OLED and QLED technology?
OLED (Organic Light Emitting Diode) technology utilizes organic compounds that emit light when an electric current is applied. Each pixel in an OLED display is self-illuminating, allowing for deeper blacks and superior contrast because individual pixels can turn completely off. This capability creates stunning visuals with vibrant colors and exceptional viewing angles.
On the other hand, QLED (Quantum Dot Light Emitting Diode) technology is primarily developed by Samsung and uses quantum dots as a light source. QLED displays utilize a traditional LED backlight that shines through layers of quantum dots to produce colors. As a result, QLEDs can achieve higher brightness levels, making them more suited for brightly lit environments, but they generally struggle to reach the same contrast levels as OLEDs.
Which TV technology offers better picture quality?
When it comes to overall picture quality, OLED technology is often considered superior due to its ability to produce true blacks and a broader color gamut.
