Samsung QLED TVs: The Technology Behind Stunning Picture Quality

Samsung Electronics has long been at the forefront of display innovation, most notably by pioneering cadmium-free quantum dot materials. This breakthrough technology has become the cornerstone of precise color reproduction and exceptional picture quality. Beyond TVs, quantum dot technology is gaining attention in sectors like medical devices and solar cells.

With the launch of QLED TVs, Samsung has redefined the television experience. By leveraging ultra-fine quantum dots, QLED displays achieve a broader color gamut and higher brightness, delivering picture quality that surpasses traditional LED TVs.

Inside a Samsung QLED TV

1. Operating Module: The Brain of the TV

• Rear Cover: Protects internal components, manages heat, houses speakers, and provides connectivity.
• Main PCB: Acts as the brain, controlling power, remote reception, and SmartThings connectivity.
• TV Tuner: Converts broadcast signals for display, essential for traditional television functionality.
• AI Processor: The Q4 AI Processor manages AI features, optimizing picture and audio for immersive viewing.
• Speakers: High-resolution audio delivers a room-filling, cinematic sound experience.

2. Panel: The Heart of the Display

• LCD Layer and Color Filter: Control light and separate colors at the pixel level for precise images.
• Optical Sheet: Concentrates backlight for brighter, more uniform images.
• Quantum Dot (QD) Layer: Converts light for vibrant, lifelike colors. Certified No-Cadmium for safer use.
• Diffuser Plate: Spreads light evenly to maintain natural illumination.
• Blue LED Backlight: Paired with the QD layer, it delivers pure colors and enhanced luminance compared to conventional white LEDs.

What Makes a Real Quantum Dot TV?

To qualify as a true quantum dot TV, three criteria must be met:

1. Presence of a QD layer
2. Sufficient quantum dot concentration
3. Blue backlight

Samsung QLED TVs are the only TVs in the world meeting these requirements, earning the ‘Real Quantum Dot Display’ certification from TÜV Rheinland. This certification highlights the unmatched quality and precision of Samsung’s QLED technology.

QLED vs. LCD: The Difference is Clear

Samsung QLED TVs deliver narrow, distinct color peaks in red, green, and blue, producing lifelike visuals with exceptional depth and richness. Traditional LCD TVs, without a QD layer, show wider bandwidths and less precise color representation, often requiring additional color correction layers that reduce light efficiency.

The QLED teardown demonstrates that every component — from the backlight to the QD layer — works in perfect harmony to deliver breathtaking picture quality. The QD layer, in particular, enhances vibrancy and color accuracy, creating visuals that truly stand out.

At IFA 2025, Samsung showcased its “Real QLED Zone,” emphasizing the importance of choosing genuine QLED technology over imitation displays. Samsung QLED TVs represent the pinnacle of display innovation, offering viewers an unparalleled premium viewing experience powered by cutting-edge quantum dot technology.
