QLED televisions represent a significant advancement in display technology, building upon the foundation of LED backlighting. The key innovation in QLED (Quantum Dot Light Emitting Diode) technology lies in the use of quantum dots, which are tiny semiconductor nanocrystals. When these quantum dots are illuminated by a blue LED backlight, they emit light of specific colors with remarkable purity and efficiency. This allows for a broader and more accurate color spectrum to be displayed compared to traditional LED TVs.

The primary benefit of QLED technology is its enhanced color volume and brightness. Quantum dots can produce vibrant and saturated colors that remain consistent even at high brightness levels, leading to a more lifelike and immersive viewing experience. This makes them particularly well-suited for displaying HDR (High Dynamic Range) content, where the contrast between the darkest blacks and brightest whites is crucial for detail and realism.

QLED TVs typically employ a full-array local dimming (FALD) backlight system. This means the LEDs behind the screen are grouped into zones that can be dimmed or brightened independently. This allows for better control over contrast, resulting in deeper blacks and brighter highlights without sacrificing detail in darker or brighter areas of the image. While QLED technology offers superior color and brightness, it is important to note that they do not emit their own light like OLED displays. Instead, they rely on a backlight, which means there can still be some light bleed in very dark scenes, although local dimming significantly mitigates this issue.
