The world of display technology is evolving rapidly, and Samsung is making significant strides with QD-EL (Quantum Dot Electroluminescent) technology. This emerging innovation, also known by various names such as NanoLED, QD-LED, EL-QLED, and QDEL, has the potential to revolutionize screen performance by offering ultra-high brightness while retaining OLED-like contrast levels.
But while this technology is promising, don’t expect to see it in mainstream 4K TVs anytime soon. Instead, its first applications are likely to be in the monitor market, where smaller panel sizes make commercial adoption more feasible.
What is QD-EL and Why is It Gaining Attention?
Currently, the two dominant display technologies are:
- LED-backlit LCDs – Bright but reliant on a backlight.
- OLED displays – Self-emissive for perfect blacks and contrast but susceptible to burn-in and organic degradation.
QD-EL aims to deliver the best of both worlds. Like OLED, it is a self-emissive technology, eliminating the need for a backlight. However, instead of organic compounds, it utilizes quantum dot LEDs, promising:
- Higher brightness than OLED
- Longer lifespan with improved energy efficiency
- Reduced risk of burn-in, a major issue with OLED panels
Samsung, along with other manufacturers like Sharp and TCL, has showcased QD-EL prototypes at recent tech expos. However, these early prototypes have been small—Samsung’s demo model was just 18 inches—highlighting the current limitations in scaling up to large-screen formats.
Why QD-EL is More Likely to Debut in Monitors First
1. Development Challenges in Large Screens
Scaling new display technologies to large TV panels is notoriously difficult. BusinessKorea reports that Samsung is facing key technical hurdles with QD-EL, particularly in stabilizing quantum dots and improving energy efficiency.
2. High Manufacturing Costs and Wastage Risks
Producing large OLED or QD-EL panels is costly, with significant material wastage due to defects. Manufacturers typically refine the process on smaller screens before scaling up. For instance, TCL’s inkjet-printed OLED technology began mass production in 2024 for 21.6-inch monitors, but the company does not expect TV-sized panels for several years.
Given these factors, Samsung’s initial QD-EL displays will likely target high-end monitors before expanding into TVs.
When Can We Expect QD-EL TVs?
While Samsung has reportedly set an internal goal to commercialize QD-EL within a few years, mainstream adoption in TVs could take longer. If history is any indicator, smaller screen formats will serve as the testing ground before the technology is mature enough for 55-inch and larger panels.
However, there’s always room for surprises. Samsung previously skipped the monitor phase when launching its QD-OLED technology in 2022, opting instead to release it directly in TVs before later adapting it for gaming monitors.

How is QD-EL different from QD-OLED?
Will QD-EL eliminate OLED burn-in issues?
How soon will QD-EL monitors be available?
Will QD-EL be more expensive than OLED?
Conclusion
QD-EL represents a major leap forward in display technology, combining the best attributes of OLED and LED. However, it is unlikely to appear in mainstream 4K TVs in the immediate future due to manufacturing challenges and cost concerns. Instead, expect its first real-world applications in high-end monitors, with a gradual expansion into larger screens as the technology matures.
