How Does QLED and Dolby Vision Work?
Quantum Dot (QLED) Technology
QLED uses quantum dot particles to enhance color brightness and accuracy. These particles improve how light is filtered, producing more vivid and realistic images.
This means colors appear more natural and less washed out, especially in bright scenes.
Dolby Vision HDR Processing
Dolby Vision dynamically adjusts brightness and contrast scene by scene. Instead of a fixed image setting, it adapts in real time.
This results in deeper blacks and brighter highlights, improving detail in both dark and bright scenes.
Dolby Atmos Sound System
Dolby Atmos creates three-dimensional audio that surrounds the viewer. Sound moves around the room instead of coming from a single direction.
This makes movies and sports feel more immersive and realistic.
AiPQ Image Enhancement
The AiPQ engine analyzes content and optimizes color, contrast, and clarity automatically.
This ensures even low-quality videos appear sharper and more refined.
