4K TVs are now the most common for purchase, offering high-quality images and a wide range of features.
But what is the difference between UHD and QLED?
In this text, we will explain the difference and show the main features so you can decide which is the best TV model for you and your home, and most importantly: how it affects the price of the TV.
The first thing to know is that the acronym UHD (short for Ultra High Definition) refers to image resolution.
There are two main variations of UHD resolution: 3840 x 2160 pixels (also known as 4K) and 7680 x 4320 pixels (known as 8K).
What is UHD?
The term 4K means that these TVs can display four times more pixels than conventional Full HD TVs.
The result is sharper images with incredible detail and vibrant colors.
We won't go into too much technical detail here. If you want to know more, Samsung offers detailed information in this article: What is 4K TV and 4K resolution | Samsung Brazil.
One important thing you should know is that 4K resolution is standardized for TV models above 50 inches.
What does that mean?
If you want to have a 4K TV, you need to buy one that is 50 inches or larger.
What Is a QLED TV?
Second step: Understanding what QLED is
The famous term "QLED" refers to the screen technology used in the TV.
QLED screens, like TVs in general, also have LEDs that emit light behind the liquid crystal screen, but the difference lies in the quantum dot compound that filters the light, brightness, and color intensity of the pixels to form the image.
These quantum dots enhance the TV's color performance and brightness, providing a wider color gamut and more precise contrast.
That QLED TVs offer vibrant colors and high brightness, providing an impressive visual experience.

It's easy to understand now.
Saying that the TV is "4K" refers to the image resolution, while saying that "the TV is LED, QLED, or OLED" refers to the screen technology (panel).
A TV can have 4K resolution and be equipped with a QLED screen, offering both high resolution and vibrant colors.
You don't have to choose between "screen" or "resolution"; you can have both!
Are you buying a TV?
Consider both features when making your choice and buy a TV that has the best of both technologies.
QLED technology is especially useful for those who enjoy playing video games or watching movies and series in environments with a lot of natural light.
Thinking only about 4K TVs, Samsung offers other models of 4K TVs, such as The Frame line.
These TVs are designed to integrate perfectly with your home's decor, looking more like a piece of art than a TV.
The Samsung The Frame line perfectly mimics a picture frame, with customizable frames and an art mode that displays famous artworks when the TV is on standby.
4K Resolution and QLED Screen
That the terms "UHD," "4K," and “8K” refer to image resolution, while the terms “QLED or OLED” refer to the screen technology (panel) of the TV.
You don't need to worry about having a "UHD or QLED" TV.
Because a TV can have UHD 4K resolution and be equipped with a QLED panel, offering both high resolution and vibrant colors.
If you think about Samsung TVs, for example, and want the best possible image quality, QLED TVs are the best choices you can make as they combine the best of both technologies.
