OLED vs QLED vs AMOLED vs Mini LED: Which is the best display?

The latest and greatest display types.

You've likely come across various display types when looking at the latest laptops, the best computer monitors, TVs, or even phones. LCD, IPS, and LED displays are somewhat outdated while the premium, sought-after panel type right now is OLED. However, you'll occasionally also hear about QLED, AMOLED, and Mini LED too. This might make you wonder what the difference is between OLED vs QLED vs AMOLED vs Mini LED and which is best.

The exact build and manufacturing processes for each display type are all rather technical. But don't worry. I'm here to explain at a high level what the differences are and what they mean for you. I'll also go over which ones are the best in various scenarios.

What is the difference between OLED, QLED AMOLED, and Mini LED?

There are some serious differences between the ways that OLED, QLED, AMOLED, and Mini LED displays are made. These differences lead to some major differences in the viewing experience. Let's start by going over how each one is made and what it means for you. 

OLED displays

Of the three display types, OLED is the most well-known, likely due to the fact that it is the oldest, cheapest, and most common option among the four. It was first developed in 1987 and the name stands for organic light-emitting diode or organic electroluminescent diode. It refers to the fact that the display doesn't need backlighting like older displays did thanks to the use of an organic compound that emits light when it receives an electric current. 

Compared to IPS, LCD, and LED displays, OLEDs offer blacker blacks, more vibrant colours, and crisper details. They're far better at portraying darker scenes in games, videos, and shows since the hues can come through more distinctly without the dark sections turning cloudy gray rather than black.

However, OLED displays aren't very flexible, which means that they aren't as durable as some other options and can break more easily if pressure is applied. 

QLED displays

QLED is the least impressive and least expensive display type that I'll mention here, but it's also the most recent type having been invented by Sony in 2013. Despite the name looking like "OLED" they aren't OLEDs at all. They're basically just LCD screens that use quantum dots — microscopic molecules that emit a different colour when light reaches them from a backlight. 

QLEDs are cheaper to produce than other display types and thus are often used to produce cheaper TVs. However, their picture quality isn't as consistent as OLED, AMOLED, or Mini LED. Not to mention, they don't provide as good colour accuracy or true blacks as the other display types do.

It's worth noting that Samsung has produced some QLED TVs that use Mini LED rather than standard LED backlighting. These cost more, are more reliable, and are considered premium QLEDs.  

AMOLED displays

An AMOLED, or active-matrix light-emitting diode, is a newer display first invented in 2006. They are basically OLED displays that utilize the aforementioned active matrix (a system where each pixel is controlled separately rather than in a group). AMOLED displays are higher quality than OLED as they are far more flexible and work using backplane technologies (physical connection points that allow circuitry to communicate between slots) as well as utilizing a layer of thin-film transistors (TFTs), which OLEDs don't have. However, they don't get as true black as OLED displays do. 

To clarify, TFTs often refer to liquid crystal displays (LCDs), but this film is also utilized in AMOLED to help better control the display's electrical flow. 

Mini LED displays

The Mini LED (or mini-LED) display (not to be confused with micro-LED) was first invented in 2000 and operates rather differently from the previous panel types since it uses backlighting by incorporating tens of thousands of miniature LED bulbs behind an LCD substrate (the glass used for TFT LCDs). The use of miniature LEDs rather than normal-sized ones used in other LCD displays allows for more control in regard to showing proper hues and exact brightness or black levels within specific areas of an image.

Much like OLEDs, Mini LEDs do a much better job than AMOLEDs of portraying true black, but they aren't quite as good when it comes to colour accuracy. However, their design allows for a thinner, power-saving build.

Overall, OLEDs tend to be the best when compared against QLED, AMOLED, and Mini LED. However, there are ways in which the other types are better. I'll go over these different categories and list the displays from best to worst, but you'll want to read through everything carefully as there are some caveats to keep in mind. 

Note: These are averages. Each individual laptop, computer monitor, TV, and any other display will be unique. There can be exceptions to the rule.

OLED vs QLED vs AMOLED vs Mini LED: Brightness

When it comes to laptops, TVs, monitors, phones, and other displays the unit of measurement used to describe brightness is in nits rather than lumens. A nit is a candela per square meter or the brightness of a candle as it shines onto a one-meter surface. The more nits a display supports, the brighter it gets. But being brighter isn't always best as there are more things to consider when choosing a display.

• QLED: This is the biggest way in which the QLED shines. Ahem. That's because QLEDs can get exceptionally bright with some being able to reach up to 1,000 nits.
• Mini LED: Currently, Mini LED displays can reach up to 800 nits making them some of the brightest displays out there. 
• AMOLED: These displays have been known to reach up to 600 nits, which is neither the brightest nor the dimmest option available.
• OLED: Talking about brightness is tricky when it comes to OLED. Most OLED panels only reach up to 200 nits, which is far dimmer than other displays. However, since these displays tend to get darker than the others they don't really need to be as bright in order to display images well. 

WINNER: In regards to the brightness prize, QLED technically takes the gold and is a popular pick for placing in bright rooms. But these displays don't have the best viewing angles, so they aren't good for large rooms. 

OLED vs QLED vs AMOLED vs Mini LED: Viewing angles

Each display is built differently, but the most ideal viewing position in each situation is directly in front at eye level when seated. Some displays look distorted or darker from the sides. Some might even have colour washout, so it's important to take viewing angles in mind when considering various panels. 

• OLED: Regardless of what angle you view an OLED display from it will consistently provide a clear, unobscured image. That's why OLED is the best in this category. 
• AMOLED: Viewing angles on these panels tend to be around the same level as OLED, but the colours are more likely to be oversaturated, which is why it takes second place here.
• Mini LED: Though better than most IPS, LCD, and LED displays Mini LED panels don't have the best viewing angle, especially when compared to OLED and AMOLED.
• QLED: Modern QLED panels tend to have a limited viewing angle of around 55 degrees, which especially doesn't make them ideal as TVs in large rooms where people might be sitting at various locations. 

WINNER: It's undisputed that OLEDdisplays have the best picture quality compared to the other three when viewed from various angles. That combined with their accurate colouring and impressive true black images make them the best here.

OLED vs QLED vs AMOLED vs Mini LED: Latency, response time, and refresh rates

When we talk about latency, response times, and refresh rates in displays, we're talking about how fast the panel is. Latency (aka lag) is all about the delay time between when the system sends a signal and when the display actually shows it. Response times are measured in milliseconds (ms) and specifically refer to how long it takes for pixels to change colours. Meanwhile, refresh rates are measured in Herts (Hz) and describe the number of times per second that a display shows a new image. 

The ideal situation is to have low latency with high response time and faster refresh rates so the display can keep up with the image it's meant to display at that moment. These measurements of speed are especially important within the best gaming monitors and best TVs for console gaming as you can really gain an edge over opponents by having faster images come to your display. That way, you in turn can respond quickly. 

• OLED: Can have less than 0.1ms - 1ms response times as well as refresh rates between 60H, 120Hz, or 240Hz. 
• AMOLED: Often have less than 1ms response times along with either 60Hz, 120Hz, or 240Hz refresh rates.
• Mini LED: Typically, Mini LEDs offer 1ms - 4ms response times and up to 240Hz refresh rates.
• QLED: On average, QLED displays have between 2ms - 8ms response times and can refresh up to 120Hz. 

WINNER: As witnessed by various testing, OLED displays are the very fastest options we have right now making them ideal for gamers or tech enthusiasts who want the very best, lag-free experiences.

OLED vs QLED vs AMOLED vs Mini LED: colour accuracy

colour accuracy refers to how well a panel can produce the tones, colours, and shades that the system wants it to display. It's measured in a few different units including sRGB, Adobe RGB, and DCI-P3 (or just P3). The closer to 100% a display gets in each measurement, the truer to life the colours displayed on the panel are. 

• AMOLED:  The technology used to create AMOLED produces the most vibrant hues, even better than OLED. You can expect 100% sRGB or very near to it. 
• OLED: These OLED displays have long been praised for their vivid colours, but other display types have been catching up in recent years. Thanks to OLEDs' tendency toward stronger contrast ratio and their ability to achieve true black, they help display well-saturated colours more effectively than many other panel types. They often reach between 98% to 100% sRGB, making them very beautiful displays to look at. 
• Mini LED: While these smaller LED lights do produce amazing colours, the contrast ratio doesn't tend to be as good as OLED. Because of this, sometimes imagery doesn't come out looking as good as on an OLED or AMOLED display. Still, Mini LED is very good at displaying well-saturated hues and often produces between 97% and 100% sRGB. 
• QLED: Of the four display types, QLED is the least colour accurate, but this isn't by much. They still tend to produce around 95% or higher sRGB and are plenty vibrant in their own right. 

WINNER: As of right now, AMOLED is the king of colour accuracy, but not by a ton. OLED and Mini LED follow right after it. Unless you're comparing screens side by side you probably won't even notice a saturation difference between them all. 

OLED vs QLED vs AMOLED vs Mini LED: Durability and dependability

When considering display durability, you need to take into account flexibility, which refers to how brittle a panel is. You also need to consider screen burn-in, an unsightly permanent discolouration of the display that resembles ghostly impressions of images on the screen as the display shows new images. 

Unlike older screens, modern burn-in isn't always caused by the image literally getting burned into the screen due to heat. For instance, when it comes to OLEDs, the modern burn-in effect is caused by degradation of the organic compound, which can lead to washed-out imagery. Note that every type of display here has been known to have burn-in issues, but some are more likely than others to actually have a problem.

• Mini LED: Thanks to the screen technologies used, Mini LED doesn't produce as much heat and is less likely than OLED to suffer luminance degradation. These types of displays also tend to be the most flexible of the panels listed here adding to their longevity.
• QLED: Several QLED displays have been specifically manufactured to have more flexible substrates, but some are more stretchable than others. Meanwhile, it is possible for a QLED to experience burn-in but not likely to actually happen due to the particle-obstructing technologies it uses.
• AMOLED: Much like OLEDs, AMOLEDs have come a long way in recent years in reducing and eliminating burn-in problems. However, it's still something you might encounter. As far as display durability goes, this kind of display can be extremely flexible thanks to the innovative technologies used to create them.
• OLED: Older OLEDs had issues with burn-in, however, the latest OLED technology has solved this issue by adding additional preventative measures, both software and hardware-based. But you need to check from one OLED device to the next to see if it is susceptible to burn-in. Additionally, OLED displays have become more flexible over the years, but some can get more damaged than others when bent or stretched

WINNER: It's a hard call in some respects, but thanks to its flexibility and lack of burn-in issues, Mini LED is the most durable and reliable display available right now.

It's an easy temptation to want to go for the cheapest display you can but remember that cheaper cost often equates to cheaper build. As the adage says, "you get what you pay for." Less expensive devices will save your wallet from getting too skinny, but they might also result in a higher chance of burn-in, reduced colour accuracy, a dimmer screen, or some other issue that will prevent you from really enjoying your purchase. Of course, going for a smaller size display can really help you save money.

But on the other hand, you don't always need the best quality to get a job done. Sometimes going for the cheapest thing is the right choice for you. 

• QLED: These displays can range a whole lot in value depending on what they're made of. However, when made with standard LEDs they can be very inexpensive. Just note that Samsung has produced a few premium QLED TVs that utilize mini-LED rather than standard LED, which make them cost a whole lot more. 
• Mini LED: Some people think that the latest Mini LED displays take a lot of work to produce and that is true. But on average, they tend to cost 10% less than modern OLEDs, making them slightly cheaper. 
• OLED: Thanks to their complex build and desirability, OLEDs tend to be somewhat costly and maintain their position as the premium, sought-after display on the market today.
• AMOLED: Due to the build that makes them more flexible, AMOLED displays tend to cost even more than OLED to manufacture, making them the most expensive display option here. 

WINNER: Truth be told, QLED displays can have a wide price range depending on what exactly they are made of. This allows them to be much cheaper than the other display types in some instances and on the same level in others. 

Bottom line: Some displays are better than others

So many variables go into determining what kind of display type is best for your needs. OLEDs tend to be the best overall due to their amazing colour accuracy coupled with their ability to display true black. Plus, they're available most plentifully as the premium display option for a variety of devices. They also tend to be rather fast and work well as gaming monitors or gaming TVs. 

However, Mini LEDs are the up-and-coming display that might give OLEDs a run for their money in a few years. These feature smaller LED backlighting than the LCD panels before them but allow for thinner, HDR visuals in a power-saving design. They make for great gaming monitors and laptop panels. 

Meanwhile, if you're set on getting a TV with the very best colour accuracy, you can't go wrong with an AMOLED. They get a fair bit brighter than OLEDs and produce some of the best-saturated hues of any display out there.

Of course, if you're keener on saving money or you need something that can be bright enough to shine in an overly illuminated room then QLEDs are a good choice. They range in quality far more than any of the other types of displays mentioned here, but if you do your research and check what technologies they employ you'll know what you're getting into. 

Think about what you specifically need from a panel before choosing which laptop, TV, monitor, or other device with a display to buy and you'll be more likely to get something that pleases you.
