The quest to find the perfect television seems to be a never-ending, ever-changing mission. Every time you might feel like you‘ve finally got a grasp on what‘s considered the best of the best at any given moment, the next latest and greatest technology comes along and shakes things up.
Take QNED vs LED, for instance. Which of these two technologies is the best TV type today? What sets these two TV types apart, and is one any better than the other? Let‘s consider their key differences and other facts below in an effort to come up with an answer.
What is QNED?
First, let‘s clarify exactly what QNED is. QNED stands for "Quantum NanoCell Emitting Diode." It is LG‘s proprietary TV display technology that combines quantum dot and NanoCell layers with mini LED backlighting.
Quantum dots are tiny semiconductor particles that produce extremely vibrant, accurate colors when illuminated. NanoCell filters use nanoparticles to absorb excess light wavelengths, improving color accuracy. Mini LEDs, as the name implies, are tiny LEDs that enable precise dimming control for better contrast.
So in essence, a QNED TV takes an LCD panel and adds cutting-edge quantum dot and NanoCell filters for exceptional color quality. It then uses advanced mini LED backlights with thousands of dimming zones instead of traditional LEDs to achieve blacks nearly as inky dark as an OLED TV.
Key Differences Between QNED and LED TVs
While both are variations of LCD televisions, QNED and LED TVs have some notable differences:
1. Backlight Technology
The most significant difference lies in the backlighting system used:
-
QNED TVs utilize a dense full array of mini LED backlights with thousands of individual dimming zones for precision black level and brightness control.
-
LED TVs use traditional larger LEDs, either placed solely around the edges (edge-lit), across the back (direct-lit), or sometimes in zones (full array local dimming).
The mini LEDs and extra dimming zones make a dramatic difference, allowing QNED TVs to render highlights far brighter and shadows much darker than LED sets.
2. Panel Enhancements
While both use LCD panels, QNED TVs add special enhancements:
-
QNED TVs add quantum dot and NanoCell filtration layers to produce a wider, more accurate color gamut with vibrant hues.
-
LED TVs utilize a standard LCD panel without these extra nanotechnology enrichments (though some do add quantum dots).
So QNED sets achieve superior color quality due to advances in quantum and nanoparticle engineering.
3. Brand Availability
There is also a difference in brand availability between the technologies:
-
QNED TVs are currently only produced by LG, who developed the technology. So far they offer QNED models from 50 to 86 inches.
-
LED TVs are made by many brands, including LG, Samsung, Sony, TCL, Hisense, Vizio and more. Sizes range from small 24-inch sets up to massive 98-inch screens.
So if you want a QNED display you‘re limited to LG, while LED sets offer abundant brand and size options.
4. Release Timeframes
Finally, there is a significant difference between when each technology debuted:
-
QNED TVs just released in 2021, making them freshly new with some kinks still possibly being worked out.
-
LED TVs first hit the market way back in 2005, giving manufacturers like Samsung and Sony over 15 years to refine image processing and perfect manufacturing.
So QNED is the flashy, unproven new kid, while LED is the reliable veteran technology with years of maturity on its side.
5 Must-Know Facts About Modern TV Technologies
Beyond just QNED and LED displays, here are five key things to know about the TV landscape:
1. Mini LED is used in many high-end TVs now beyond LG‘s QNED models. Brands like Samsung, TCL, and Sony are adding mini LED backlights to boost contrast compared to standard LED TVs.
2. OLED reigns supreme in picture quality. With per-pixel lighting control, OLED TVs still outperform even the best mini LED LCDs when it comes to perfect contrast and viewing angles.
3. No backlight means no blooming on OLEDs. Even with advanced mini LED dimming, LCDs can still exhibit some light blooming. OLED‘s lack of backlight completely eliminates this issue.
4. Quantum dots augment LCD and OLED panels. The tiny nanocrystals expand color volume dramatically, whether placed in front of an LED backlight or OLED module.
5. Brand abbreviations are mostly just marketing. OLED and LCD are the core technologies. Letters added on like QLED, QNED, ULED etc denote backlight and filter upgrades to those base types.
The Story Behind QNED‘s Development
The name “QNED” may seem like random letters thrown together with little meaning. But there’s an informative history and technological method to how LG arrived at the development of QNED TVs.
It began when LED TVs largely replaced legacy CCFL-backlit LCD televisions during the 2010s. While LED backlights substantially improved contrast, viewing angles and efficiency compared to CCFL backlights, they still had some inherent limitations.
Most notably, while fine for overall illumination, large LED backlights struggle to match the pixel-level precision of OLED displays. This manifests in subtle light blooms and haloes in dark scenes. They also cannot match OLED TVs infinite contrast since LEDs can’t dim down fully to zero black.
Engineers theorized that shrinking the actual LED size could enable far more discrete control. If thousands of tiny LEDs could be packed tightly together and controlled individually, LCD black levels and contrast could dramatically improve.
Thus emerged mini LED backlight technology – similar concept but with each LED shrunk from roughly 1 mm wide to just 0.2 mm. This let engineers cram over 25 times more dimmable zones into the same space.
Armed with these game-changing mini LED backlights, LG set about constructing the ultimate next-generation LCD TV. They started with a high-performance LCD panel then added crucial NanoCell and quantum dot enrichment layers. Nanoparticles filter light while quantum dots splash vivid color.
The resulting television – christened “QNED” – represents the pinnacle of LCD engineering. Black levels can dive impressively dark thanks to the swarms of dimmable mini LED zones. Hues look rich and realistic with quantum dot expansion and NanoCell filtering.
By coordinating cutting-edge backlight, LCD, and filter improvements into one package, LG has ushered elite-caliber image quality into the LCD television world with QNED.
QNED vs. LED TVs: Pros and Cons
How do QNED and LED televisions stack up against each other? Here’s a breakdown of the key advantages and potential drawbacks of each display innovation:
QNED TV Pros:
- Phenomenal contrast from mini LED backlights and abundant local dimming zones
- Vibrant, realistic colors via quantum dots and NanoCell filtration
- Impressive brightness capabilities for striking HDR highlights
- Very wide viewing angles maintained compared to standard LCD TVs
QNED TV Cons:
- Restricted to select premium LG TV models for now
- Possible manufacturing defects since the technology is so new
- Can’t match an OLED TV’s pixel-perfect black levels and contrast
- Higher price tag than average LED televisions
LED TV Pros:
- Proven, reliable technology polished over 17+ years of progress
- Abundant brand, size, price and feature options to choose from
- Impressive brightness capabilities, some with wide color gamuts
- Generally more affordable price points, especially for smaller sizes
LED TV Cons:
- Mediocre native contrast ratio, shadow detail and black levels

As we can see, both technologies bring unique advantages and weaknesses to the table. Ultimately, QNED televisions represent the cutting edge of LCD image quality thanks to revolutionary backlight and color improvements. But LED TVs offer battled-tested dependability and excellent brightness at more budget-friendly prices.
