Is it time to upgrade your TV? Shopping for a new TV can be daunting. Technology and terminology can be very confusing. Fear not, we are here to help! We put together this helpful guide to get you up to speed on QLED vs UHD TV technology.
If you’re researching TVs to buy, you’ve probably come across two industry terms – QLED and UHD. QLED is a category name for TVs that uses a technology called a quantum dot. UHD is also known as 4K. What do these mean, and what’s the difference? Let’s find out.
First, it is important to understand, that there’s no “one or the other” or “one is better than the other” here. QLED and UHD describe completely different technologies.

What Is UHD?
First, let’s start with UHD, which stands for “Ultra High Definition“. This simply refers to the TV having a 4K display resolution (four times the pixel density of full HD).
It has a better dynamic range which leads to more detailing and better color handling compared to conventional HD. Now there are some UHD TVs available with an astounding 8K resolution.
UHD is not a “new” type of TV technology like QLED, but rather an improvement on the “full HD” 1080p LCD (liquid-crystal display) TVs. With more and more 4K content becoming available to watch, UHD is a feature you’ll want for your next TV.
A UHD TV operates like a QLED TV in that it has an LED backlight and LCD screen, but it lacks the QLED TV’s quantum dots used to improve color and brightness.
The most important thing to remember is that UHD is not technically a type of TV, but rather a description of its 4K resolution. What’s confusing is that although UHD and 4K are not the same technology, the terms are often used interchangeably.

What Is QLED?
Next, let’s dive into QLED, which is a category name for TVs that use quantum dot technology to create or enhance color. QLED stands for “Quantum Light-Emitting Diode”. The word “quantum” refers to the use of tiny particles called quantum dots. Quantum dots are tiny particles. Quantum dots emit red and green light when blue light is shined through them.
The light from the LED panel travels through a quantum dot screen before reaching the liquid-crystal display (LCD) at the front of the QLED TV. This produces the recognizable images we watch.
The Differences, In a Nutshell
To summarize, these are the biggest differences between QLED vs UHD TVs:
- QLED technology uses an LED backlight to hit a screen of quantum dot particles that then supercharges the TV’s individual pixels for brightness and color beyond the standard quality seen in other LCD TVs.
- UHD TVs are simply higher-resolution versions of the standard LCD TV. Both OLED and QLED TVs usually offer UHD resolution!

How does QLED (Quantum Dot Technology) work?
All QLED TVs have a quantum dot filter. It’s a film of tiny crystal semiconductor particles which replace the red, green, and blue color filters that old TVs used. Quantum dot filters can precisely control their color output.
However, there are differences in quantum dot implementation. Quantum dot offers a step-up color performance, but not all quantum dots are created equal.
There are varying levels of quantum dot implementations available in the industry that provide different levels of color performance. Color is measured using what’s called the rec2020 color space. The more color space coverage the better. Color space is the standard being used by Dolby Vision and other HDR formats. It is the widest color space currently available for electronic displays.
You’ll find the ‘QLED’ label on a few TV brands, including TCL and Hisense, but generally, it refers to a Samsung TV. Recently, Vizio has entered the QLED TV market, utilizing Samsung’s quantum dot technology.

QLED vs UHD TV: Quantum Dot FAQ
What is QLED?
A TV panel technology that uses quantum dot technology to create or enhance the color of TV screens.
Which is better QLED or UHD?
One is not better than the other. UHD is not technically a type of TV, but rather a description of its 4K resolution. UHD and QLED describe completely different technologies.
Is QLED better than 4K?
QLED TV is going to be better in terms of color accuracy which leads to a great viewing experience.
What is the difference between QLED and premium UHD?
The main difference between QLED and Premium UHD is that the QLED is powered by Quantum dot TV display technology while the Premium UHD is a standard used in 4K range TV displays. Premium UHD established a consensus for 4K Ultra HD specifications. They focus on the clarity and sharpness of the picture quality to create realistic images.
Are QLED TVs expensive?
Some certainly are but there are mid-range models that won’t break your budget.
Is QLED really worth the extra money?
It’s a step up from regular Ultra HDTVs. QLED panels have made for some incredible high-end televisions, with incredible bright screens and strong upscaling ability. Some are now offered at mid-range prices.
