Mini-LED and QLED are two TV technology acronyms that have more in common than you might think. Technically, these are both types of LED lighting, but the first is a type of LED lighting, and the second is what you get when you combine a TV’s LED backlight with a layer of quantum dots (hence the “Q”). ). ). If this explanation makes you confused, please be a little patient, we will try to explain it better below.
Let’s take a closer look at mini-LED and QLED technologies, starting with the most important element: LEDs.

LED: size matters
There are currently two main types of TV displays: self-emissive displays such as OLED and MicroLED, where each individual pixel emits its own brightness and color, and backlit displays such as LED and QLED TVs, which require a separate backlight. light source, and the LCD matrix and color filters take care of the color and adjust the brightness.
LED and QLED TVs (which are essentially a type of LED TV) use an LED lighting source. But not all TVs using this technology are created equal.
Inexpensive LED TVs may use just a few LEDs arranged around the edges, hence the name edge-lit TVs, while more expensive TVs use hundreds of LEDs arranged in a grid behind the LCD matrix.
The general rule here is that the more LEDs you can include in the backlight, the brighter it will become and the more control you will have over that brightness in very specific areas of the TV picture.
In an ideal world, a TV would have one LED per LCD pixel, but this is not possible now. There is a physical limit to the number of typical LEDs in a given space, which is determined by the size of the LEDs. The larger they are, the less you can use.
Mini-LED: a big leap to a small one

This limitation on the number of LED emitters, based on the physical size of each LED, is what makes Mini-LED technology so interesting. Mini-Led breaks the previous size barrier by introducing diodes that are much smaller than any that have been used to date. We’re talking about the ability to install thousands of LEDs in a space that previously could only accommodate hundreds.
A 4K TV has just over eight million pixels, so mini LEDs are still significantly larger than one pixel, but that’s ok, mini LEDs are much smaller than standard LEDs, you can still see a big difference.
It’s about light (and darkness)

As we said above, more LEDs results in more brightness, which is useful for HDR and also makes the image visible in bright rooms, but also results in better darkness.
To achieve the deep, dark blacks in a certain part of a backlit TV screen, the kind you’d expect when watching space scenes, you’ll need to turn off the backlight in that part entirely. If you have hundreds of LEDs running, you can control which areas of the screen are dark. This is called full array local dimming (FALD).
But even with local dimming, if there is a large difference between the brightest part of the screen and the darkest part, it can result in blur, an effect where light appears to leak from the brightest part to the darkest part.
With Mini LEDs, local dimming becomes much more effective as the number of adjustable zones increases and their size decreases, making it easier to isolate dark areas from light ones. Not only does this make the dark parts of the screen darker, but the contrast created makes the lighter parts appear even brighter.
So far, we haven’t seen a Mini-LED TV as black (and colorless) as an OLED, but the gap between backlit TVs and broadcast screens like OLED TVs is smaller than ever.
Where does QLED fit into all this?

QLED, or quantum dot LED, uses nanoparticles that have a special property: when light hits them, they emit their own light. When these quantum dots are strategically placed between the backlight and the LCD matrix, it improves brightness and color.
This was before the advent of QD-OLED technology. Combining the best of QLED and OLED displays, these cutting-edge TVs are currently produced by Samsung and Sony and are simply incredible. These TVs feature ultra-high-power LED backlights and quantum dots that work in unison to increase the amount of light emitted by the OLED display’s self-emissive pixels.
The end result is bright and rich, with cinematic colors, contrast and inky black levels. We’re big fans of the Samsung S95C, our favorite QD-OLED of 2023, and we’re sure we’ll see this type of imaging technology adopted by many more brands over time.
Does Mini-LED have other advantages?
Mini LED TVs are otherwise the same as standard QLED TVs, so the same benefits apply to both: screen sizes can be larger and prices can be lower than OLED TVs (at least for now moment).
As the technology matures, we can expect Mini-LED to play a major role in improving picture quality and lowering prices of LED and QLED TVs.
Improved energy efficiency can also be achieved because a large group of smaller LEDs can achieve the same brightness as larger LEDs, but require less power to do so.
Who makes mini LED TVs?

TCL started the mini LED TV movement with the release of the first mini LED TV, the Roku TV 8 series, in 2019. Since then, TCL has released several mini LED TVs, with the TCL QM8 2023 being one of the latest and best. companies.
You can also find mini LED TVs from brands such as Samsung (QN90C 2023), Sony (X95K 2022) and Hisense (U8H 2023).
