Check OLED vs Mini LED vs MicroLED: Comparison view
The latest advancement in TV technology is mini LED. But how does it compare to OLED, the current market leader in high-end TVs? The latest advancement in LCD display technology, mini LED is the result of decades of research and development. In 2022, several major TV manufacturers including Hisense, LG, Samsung, Sony, and TCL will launch Mini LED TVs. Most of them refer to their Mini LED lines by various confusing names. For example, LG refers to its Mini LED TVs as QNED, while Samsung refers to its version as Neo QLED. The ‘LED’ bit of Mini LED, on the other hand, only designates the type of backlight being used; is a transmissive technology based on LCD panels. This indicates that the intrinsic LCD defects are still present. Avoid confusing it with Micro LED, which is a completely different concept and is only used in the largest and most expensive panels available today. Our guide on Micro LED has more information about it.

Organic Light Emitting Diode technology, better known as OLED, has been around for the better part of a decade and is used in televisions as well as phones and other small-screen handheld devices. MIT uses millions of tiny, grown, self-illuminating pixels that can be individually turned on or off, meaning darker areas of a screen can be deeper and more immersive, with no light bleeding from neighboring pixels. In fact, because they can be turned off completely, black levels tend to be better than most other displays on the market today. Power consumption also benefits from the lack of a backlight, as does the depth of an OLED TV, as the panel can be just millimeters thick. Some OLED TVs have separate media connection boxes, which allow the panel to sit flush with the wall.
OLED TVs are also known for their excellent color saturation and accuracy, although the brightness is typically not as high as high-end LED TVs. Another caveat for OLED display technology is that, because it’s organic, its lifespan is shorter than its rivals. The effectiveness of pixels can fade and a set can look less bright or vibrant over time. However, this can take many years. Perhaps the most important thing to note is that OLED is similar to older plasma TV technology in screen retention. You can often see static images remain for a while. In the worst case, you may even experience permanent screen burn, although TV manufacturers have introduced a number of fail-safe measures to help prevent that from happening on newer models.
Mini-LEDs
- Use for: LG, Samsung, Philips, TCL
- Positives: High brightness, better black levels compared to other LED TVs, more affordable
- Negatives: Thicker TV due to backlight behind LCD substrate, some light bleeding between pixels
Mini LED is a reasonably new technology for televisions. It’s also the only one here that refers to the backlight rather than the display technology itself. A Mini LED backlight is similar to other LED technologies that sit directly behind an LCD substrate, and like those, it shines light through pixels that don’t automatically light up to give you an image on the screen. However, unlike other LED backlights, even local dimming, it is made up of many thousands of tiny LEDs that can be turned on or off in multiple much smaller zones. For example, LG’s current range of Mini LED TVs use 30,000 LEDs in the backlight, which sits directly behind the LCD panel. These are grouped into around 2,500 zones, which can be precisely turned on/off, dimmed or brightened as required.
The benefit of this technology over conventional LED backlighting is that it can be more accurate and therefore provide better black levels. Color saturation and accuracy are also improved (as is the case when you have better control over dark areas of a screen). There is also less light bleeding, as the LED zones are much smaller than usual. The end result couldn’t compare to OLED or Micro LED, which are even more precise with each pixel self-illuminating, but you get a much better picture than you would normally get with LED TV technology. Another benefit of Mini LED TVs is that they are the cheapest of the three that are made here. As a result, prices can be more attractive.
MicroLED
- Use for: Samsung
- Positives: Excellent brightness, excellent black levels, modular TV technology, so it can be made in many different sizes
- Negatives: Extremely, prohibitively expensive, can currently only be done on massive screen sizes
Like OLED, Micro LED technology uses self-illuminating pixels with miniature LEDs of various colors that combine to present a highly accurate image without the need for backlighting. This features OLED-like performance, especially when it comes to black levels, as each pixel can be turned on or off at will. However, since the pixels are made of non-organic material, they can also technically shine brighter, which could give Micro LED TVs much higher contrast and brightness. HDR control, therefore, is more pronounced in a Micro LED panel, with more extreme black and brightness levels than other technologies can achieve. Micro LED technology is also more flexible, as shown by Samsung’s The Wall, which is modular and built with different pieces of screens assembled to make a much larger screen.
However, there are a couple of caveats with Micro LEDs. First, since it is made up of groups of pixels that are one millimeter (a module) in size, it can only really be used on larger screens or it will lose resolution. The smallest Micro LED TV released so far is 77 inches. The original Wall TV was 4K and 146 inches. However, other manufacturers are developing micrometric modules, so this could be a problem solved in the future. The other drawback of Micro LED is that it is currently extremely expensive. For example, Samsung’s 2021 110-inch Micro LED TV costs more than $150,000.
