Is QLED Worth It? (everything you should know)


Why should you invest in a QLED TV? With different brands and experiences, choosing a TV might be a challenge.

But what makes the QLED worth it or is it just a waste of money?

QLED TVs are ideal for those who engage in routine movie streaming, games, or programs. It delivers the best viewing experiences you can ever imagine.

What is QLED?

QLED or quantum dot LED displays are next-generation televisions that look to improve on OLED technology. They use an array of microscopic LEDs situated in front of a film-coated with red, blue, and green quantum dots (hence the ‘Q’ in QLED). 

This nanocrystal adds ultraviolet light needed to produce white backlight for improving color reproduction. This new display technology allows manufacturers to enhance blacks, contrast ratio and viewing angles over current LED TVs.  

This higher performing LED currently costs around 30% more than your standard LED TV but looks set to lower as manufacturing efficiency improves along with demand driving further economies of scale.

QLED Technology stands for Quantum Light Emitting Diode, or an advanced version of an LED to create light that emits more than just one color. It is supposed to be the next step in OLED technology but won’t require an expensive material like quantum dots.

QLED, also known as metal-ligand complexes, is thought to be the successor of existing OLEDs (organic light-emitting diodes) and LCD screens. A QLED screen would combine the best features of LED and OLED technologies by producing brighter images with darker blacks that are more energy-efficient than their counterparts.

QLED is a self-emissive display technology that brings the benefit of improved image quality, more vivid colors, and better response time. 

The main difference between QLED and OLED is the fact that QLED displays function as an ‘energy amplifier’ using battery power to increase brightness as well as backlight control by redirecting light from areas of dark content. 

This allows for brighter images without compromising on energy consumption.QD Vision has been a pioneer in quantum dot technology for years now, however, they failed to bring it into mass production because of several problems with its color complexity.

Samsung’s solution was to use red and green quantum dots together with blue LEDs rather than having all three colors separately.

What are the benefits?

With this new technology, you’ll get more vibrant images with high color volume and sharp image quality at wider viewing angles. 

QLED TVs use a specialized film of quantum dots which increases the range of colors and enhances brightness for deep blacks and brilliant whites. This means that these new next-generation televisions can produce images that go way beyond current LED and OLED displays.

When to buy?

If you don’t own a 4K TV yet then the time is now. With prices of Sky Q packages falling almost daily it would be silly not to at least upgrade your TV right now as these will only become cheaper over time. 

Wait any longer and they may even cease production before you know it (looking at LG’s OLEDs). Right now, QLEDs are at their best and you should take advantage of any upcoming deals.

When is it not worth buying?

If you already own a 4K TV or even a home theatre system then this may not be for you right now. Obviously, the lower price would definitely help but specs on these can’t compete with some of the bigger names in 4K UHD technology such as LG and Panasonic just yet. 

Although Sony and Samsung have some fantastic panels out there they won’t quite match the strength of OLED when it comes to perfect blacks showing from deep scene shadows to complete darkness which helps produce a more dynamic image. However, if money isn’t an issue then it certainly wouldn’t be a bad idea to upgrade.

Will QLED go mainstream?

If manufacturers continue to produce OLED panels then the higher end of the market would be a solid bet. Of course, this is largely dependent on how much demand there will be in which case it may even take a couple of years for them to become affordable to the majority. But you can always watch this space and wait for new launches from Samsung and Sony in 2018 onwards.

What is the difference between OLED and QLED?

Both OLED and QLED are considered state-of-the-art flat panel display technology. However, there are some variations between these two technologies.

The most important distinction between OLED and QLED is that OLEDs emit light due to the electroluminescence effect that occurs when electricity passes through a diode or semiconductor device. 

The main advantage of this method is ultra-thin panels which makes them suitable for implementation in TV screens and other large consumer displays such as cell phone screens.

Another major benefit of using OLEDs over traditional LED panels is superior contrast with deeper blacks and brighter whites which leads to much more vivid picture quality.

The benefit of QLEDs over OLEDs is that they use the same underlying technology (QLED utilizes quantum dots) but rather than rely on organic materials, they use inorganic semiconductor material instead. 

This has several advantages including less degradation of the display over time (image burn-in) and brighter colors at wider viewing angles. The downside of this method like OLED is that it leads to thicker panels which are not suitable for mobile devices such as smartphones.

QLED vs OLED screen size for TVs

Another major difference between these two technologies is the scale whereby both are suitable for large consumer displays whereby QLED screens tend to be larger than OLEDs due to their thickness properties. 

At present, QLED is the only commercially available large-sized direct-emission display that can be mass-produced. Therefore, due to its commercial availability, most of the high-end TV screens on the market will utilize QLED technology while OLEDs are mostly implemented in smartphones and display devices where form factor is important.

QLED vs OLED screen lifetime for TVs

The degradation rate of both quantum dot LED (QLED) and organic light-emitting diode (OLED) panels also tend to vary significantly depending on their manufacturing process.

For QLEDs, they use a coating based on indium zinc oxide which has been proven to last longer compared with standard LED displays that are made up of organic materials which have short lifespans.

On the other hand, OLEDs degrade over time as the organic materials gradually become thinner and unable to generate light. However, even though OLED panels have shorter lifespans, this is a relatively short period of time given that a typical TV will be replaced after 10 years.

QLED vs OLED screen cost for TVs

The final major difference between QLED and OLEDs is their price which also affects consumer purchasing behavior. Generally speaking, QLED panels are more expensive than traditional LED displays because there is less supply in terms of manufacturing capacity due to their complex manufacturing process. 

In addition, only one company currently has the ability to produce Quantum Dot LED technology on a commercial scale. 

While both technologies have been researched extensively for many years, QLED is still a relatively novel technology. On the other hand, OLED TVs are very expensive as they utilize more complex manufacturing processes due to the usage of organic materials. 

In terms of prices, it is currently believed that QLED panels have better value for money whereby despite its higher price tag, it does not have any problems with image burn-ins or short lifespans compared with OLEDs which tend to cost much less initially but do suffer from these issues over time and therefore need to be replaced after a few years (estimated at 12 months).

What’s next? What comes after QLED?

Although QLEDs appear to be superior in most aspects over both OLED and LED televisions, there is no doubt that OLED panels will continue to be developed in the future as the technology is still relatively new and very expensive. 

In addition, OLEDs may become much cheaper to produce over time as manufacturing processes are improved over time. Hence, it cannot be ruled out that OLED TVs will eventually become a viable alternative in terms of price or even surpass QLEDs in the long term due to their inherent benefits over both quantum dot LED and traditional LED displays.

QLED has greater accuracy in terms of color points

QLED displays are more accurate when it comes to delivering colors. For example, saturated green and deep reds will appear closer to the reference of D65 (or 6500 K) white points on QLED TVs than regular LED TVs. 

This accuracy is possible because of better light transmission in the quantum dot layer which allows for tighter packing of these nanoparticles hence eliminating chances of any chromaticity distortions. 

It also helps individual quantum dots emit specific colors without creating additional color mixtures again due to more accurate color control during manufacture. 

Such close proximity between the TV panel and quantum dots results in greater light uniformity on QLED displays offering deeper blacks and brighter highlights. Hence, viewers can easily spot differences between dark and bright areas on the screen.



Based on available information today, it would make more sense to pick a QLED television if you want an aesthetically pleasing TV at a reasonable price with deep blacks and bright colors resulting from its high-quality display technology, which also does not have any issues with image burn-in or short lifespans. 

However, if you are looking for something much cheaper then OLED TVs will be the better choice due to their lower price tag.
