OLED And QLED: Know The Difference, Prices, Specs

0

Nowadays customers have access to more TV technology options than ever before. Now all the TV technologies create excellent picture quality and offer a wide range of additional advantages. Reading about television though, could feel like trying to learn a foreign language because there are many alternatives. OLED, Quantum dots, tiny LED, and a long list of others might all appear to merge.

Television technology is on its peak right now. With streaming, we have access to an almost limitless amount of content 24 hours a day. Ultra HD 4K is now well established, 8K TVs are growing more popular and HDR is widely available.

To select a TV for your user use, it is necessary to learn the difference between them so that you can know which one is more suitable for you. The contrast between OLED and QLED, the two competing technologies in the high-end TV market, is one of the recurring confusions. What precisely are they, how do they differ, which one is more powerful, and which should you choose if you want the clearest picture? Let us give you the details.

What is the Difference Between OLED and QLED?

LG Display is the only company that makes OLED TV panels. Such panels are sold to LG Electronics, a sibling company that uses them to make some of the best TVs. Because LG Display also sells OLED panels to Sony, Vizio, Philips, and Panasonic, you can also find OLED televisions from these companies. Even while OLED TV panels are comparable, you will still detect differences in picture quality between models due to Sony, LG, and other manufacturers’ proprietary image processing.

QLED

Quantum Light-Emitting Diode is known as QLED. That means a QLED TV is similar to a standard LED TV, except that it uses small nanoparticles known as quantum dots to boost its brightness and colour. Sony first presented the technology in 2013, but soon after that, Samsung started selling its QLED TVs and formed a licensing agreement with other producers. As a result, QLED TVs are now available from Vizio, Hisense, TCL, and numerous other small brands in addition to Samsung.

Despite the coolness of quantum dots, a QLED TV nevertheless generates light in a manner similar to that of a standard LED TV: by using a backlight placed behind a conventional LCD panel composed of hundreds (or in some cases, thousands) of LEDs. The names LED and QLED are derived from these LEDs.

The colour filters work in tandem with the LCD panel, which is made up of millions of tiny shutters that open and close too quickly to be seen, to produce the image you see by allowing the proper amount of light and colour to escape and reach your eyes. Although it is a sophisticated technology, it occasionally fails to produce correct on screen blacks since it depends on dimming the LED backlights and employing the shutters to block the remaining light.

OLED

Organic Light-Emitting Diode is the official name of OLED. Unexpectedly, the name’s “Light Emitting-Diode” component has nothing to do with an LED backlight. It refers to the fact that every single pixel in an OLED display is also a teeny, tiny LED light and a very thin one that can create light and colour in a single element. In other words, since each OLED pixel generates its light, OLED TVs do not require a backlight.

This design has several benefits, but most people would say that the outstanding black level possible with OLED TVs is the largest benefit. An OLED TV turns off the pixel, unlike a QLED or LED TV that must reduce its backlight and block what is left for gloomy scenarios. When a pixel is off, it doesn’t produce any light or colour. Thus, the area is as dark as when the TV is off.

OLED TV panels are only produced by LG Display. It sells such panels to LG Electronics, a parallel business that utilises them to create some of the best TVs. You will also find OLED televisions from Sony, Vizio, Philips, and Panasonic because LG Display also supplies OLED panels to these businesses. The image processing done by Sony, LG, and others is proprietary, so even while the panels are largely equal, you’ll still notice variations in picture quality among OLED TVs.

QLED vs. OLED: Features

Now that you are aware of what each of those letters means in terms of display technology, let’s compare QLED vs. OLED in the areas that are most crucial when choosing a TV. When spending a lot of money on a new TV, brightness, contrast, viewing angles, and other key performance variables like response speed and longevity are all crucial elements to consider.

Brightness

The brightness of QLED TVs is a significant benefit. These LED backlights may be exceedingly, agonisingly bright because they use independent backlights rather than relying on each pixel to produce its light. You can have a more than bright display to be viewed clearly in even the most luminous illuminated environments when you combine that light with a quantum dot’s capacity to maximise that light by producing brighter hues in the colour spectrum without losing saturation.

Based on pure brightness, OLED screens are incomparable. Simply put, each light-emitting pixel can’t generate the same amount of light. This is not a concern in a dimly lit space. I contend it is preferable because OLED can produce the same contrast with less brightness. However, QLED TVs are more noticeable in well-lit areas or where a lot of daylight enters via windows – especially if HDR material is being played in these settings. Overall, OLED panels have improved in brightness over the years but still fall short of QLED TVs in intelligence.

Response Time, And Input Lag

The time a pixel changes from one state to another is referred to as response time. The sharper the visual, particularly in scenes of rapid-fire action, the faster the response time. OLED TVs are orders of magnitude faster than QLED TVs, even though there may be a speed of response time beyond which the human eye cannot distinguish between differences.

Compared to OLED’s response time of roughly 0.1 milliseconds, typically 2 to 8 milliseconds, typical QLED response times sound very good. Yes, there is no contest.

The difference between acting (such as pressing a button on a game controller) and seeing the outcome onscreen is known as input lag. As a result, input lag is primarily a problem for games; it has no discernible impact on passively watching information.

Additionally, the degree of input lag you encounter has less to do with the type of display technology used than with how much picture processing takes place on your TV in the background. If you disable all further video processing or only use the TV’s Game Mode, which accomplishes the same thing, both QLED and OLED TVs may achieve very low levels of input latency.

Refresh Rate

Another category that will naturally matter more to gamers than non-gamers is the refresh rate. The refresh rate is the frequency at which a television changes what is displayed on the screen. It is closely related to frame rate, which refers to how frequently your TV program, movie, or video game updates the TV.

You won’t experience any issues as long as these two rates are close multiples, such as a frame rate of 30 frames per second and a refresh rate of twice that (60 Hz). This is hardly ever a worry because ordinary TV content, such as movies and TV shows, is always transmitted at constant frame rates.

However, certain PC and console games will alter their frame rate from one scene to the next. TVs require a feature known as VRR, or variable refresh rate, to maintain everything looking as it should. This enables your TV to adjust its native refresh rate to keep up with these frame rate fluctuations. When used with the kinds of games that demand VRR, a TV that doesn’t support VRR may have undesirable side effects, such as screen tearing.

Both OLED and QLED TVs come with VRR versions. VRR TVs are available from Samsung, Sony, LG, Hisense, and TCL. VRR compatibility is a crucial feature to look for if you’re a PC gamer who desires a big-screen gaming experience. Overall, OLED dominates this category due to its unrivalled excellence in response time and refresh rate.

Viewing Layout

The ideal viewing angle for QLED panels is dead centre, and as you go further from side to side or up and down, the picture quality declines in brightness, colour, and contrast. Despite the TV manufacturers’ best efforts to fix the problem, it is always apparent, even if the intensity varies between models.

OLED screens, in contrast, may be viewed at extreme viewing angles (up to 84 degrees) without any luminance reduction. Anti-reflective coatings have helped some QLED TVs’ viewing angles, but OLED still has a distinct advantage. Therefore, an OLED TV is excellent for you if you like to organise family screenings of your favourite movies and want to ensure that there isn’t a terrible seat in the house.

Lifespan

According to LG, it would take 54 years of five-hour viewing sessions a day for OLED TVs to dim to 50% brightness. It remains to be seen if that is accurate, given that OLED TVs have been widely available since 2013. Even though QLED is a more recent technology, its backlighting source, LED, has a long and successful history. We will give this category to QLED for that reason.

Levels of Darkness and Contrast

The distinction between a scene’s darkest and brightest areas is known as a contrast. To obtain good levels of contrast, a TV doesn’t need to make the brilliant areas too bright if it can give a genuinely black dark area. Because of its capacity to become entirely black when necessary, OLED reigns as the clear champion for black levels.

Contrarily, QLED TVs are compelled to decrease their LED backlights and block the remaining light, which is incredibly challenging. As the light leaks onto the portion of the screen that is supposed to be black, it might cause a phenomenon known as “light bleed.”

Right now, OLED is the winner in this debate as a pixel remains completely dark if it doesn’t receive power because it can’t emit light.

Size

OLEDs have advanced considerably. OLED screens may be as large as 55 inches while the technology was in its infancy. The price of an 88-inch model puts it out of reach for most people at $30,000, although screen sizes as large as 97 inches are currently feasible. At higher altitudes, QLED technology is simpler and less expensive to produce. Although Samsung’s largest consumer model, the 98-inch QN800B 8K Neo QLED TV, costs $15,000, the 85-inch model is only $6,500. QLED wins in this debate.

Power Usage

As you are well aware by this point, OLED displays don’t need an extremely bright backlight. Because of how much electricity those backlights need, OLED TVs are intrinsically more energy-efficient. Compared to QLED TVs, they also produce less heat.

Price

Previously, QLED TVs would have easily won this category, but OLED TV prices have decreased, and an equivalent QLED TVs now cost roughly the same (or more, depending on the size). The biggest number of OLED-based TVs will be produced in the coming years, and as it is customary, as manufacturing increases, so do prices.

Keep in mind that, unlike OLED TV, there is a wide range in picture quality with QLED TVs because there are many more variables in their design, picture processing, and build if you encounter inexpensive QLED TVs while shopping around. Some of them are reasonable. Only the best QLED TVs can compete with OLED in terms of visual quality.

Regarding screen size price per inch, QLED continues to be the victor. However, the difference is closing every year.

Advantages of OLED

  • In comparison to the crystalline layers in an LED or LCD, the plastic, organic layers of an OLED are thinner, lighter, and more flexible.
  • OLED substrates can be flexible rather than stiff because the light-emitting layers of an OLED are lighter. Instead of the glass used for LEDs and LCD substrates, OLED substrates can be made of plastic.
  • LEDs are not as bright as OLEDs. The conducting and emissive layers of an OLED can be multi-layered because the organic layers are significantly thinner than the comparable inorganic crystal layers of an LED. Additionally, glass is needed to sustain LEDs and LCDs, and glass absorbs some light. Glass is not necessary for OLEDs.
  • Unlike LCDs, OLEDs do not require backlighting. OLEDs produce light directly and use a lot less power than LCDs as they don’t need backlighting. Particularly for battery-powered gadgets like cell phones, OLED is crucial.
  • OLEDs may be created in bigger sizes and are simpler to fabricate. OLEDs may be formed into broad, thin sheets since they are essentially made of plastic.
  • OLEDs have broad viewing angles of roughly 170 degrees. Because LCDs function by obstructing light, they are inherently difficult to view from some angles. OLEDs have a much broader viewing angle because they emit their own light.

Disadvantages of OLED

Although OLED appears to be the ideal technology for all types of displays, there are significant drawbacks as well:

Manufacturing:  Currently, manufacturing procedures are pricey.

Water:  OLEDs are readily damaged by water.

Advantages of QLED

The following are QLED’s advantages or benefits. Products using QLED will last longer since the quantum dots used in their manufacture are better at resisting moisture.

  • It doesn’t need an expensive vacuum evaporation technique because of its better resistance to moisture. As a result, the QLED is inexpensive.
  • It is available in larger display sizes, giving customers more alternatives.
  • It is lightweight and thin.
  • The rate of switching (from ON to OFF) is really quick.
  • Brightness is 50–100 times brighter than CRT and LCD display types, respectively.
  • The power consumption is reduced. In addition to having a brightness boost of between 30 and 40 percent over OLED screens, QLED screens are two times more energy efficient than OLED ones.
  • Unlike OLED TVs, QLED-based TVs are not prone to burn-in.

Disadvantages of QLED

The following are QLD’s shortcomings or drawbacks:

  • QLEDs can’t create light on their own. QLEDs instead employ a backlight device to provide illumination.
  • TVs using QLED technology have a “light bleed” problem. In some scenes, this effect can be seen. It causes a little haze to form around bright objects, blurring lines that should normally be clear.
  • The ideal viewing angle for QLED-based display screens is dead centre. When a spectator moves up and down or side to side, the picture quality suffers in terms of both colour and contrast.
  • less Saturated blue

A Quick Comparison: OLED vs. QLED

Most contemporary TVs employ LCD (liquid crystal displays) to regulate where light is displayed on your TV and LED displays (light emitting diodes) to serve as a source of light behind the screen. QLED and OLED are two distinct technologies premium TVs use to improve the viewing experience.

What distinguishes an OLED from a QLED television? I have opted to respond to this frequently asked question with a comparison and an educational table of useful bullet points.

 

QLED OLED
  • Quantum dots are used in QLED TVs to produce a wide colour range reminiscent of the colour and brightness we see in real life. 
  • To preserve colour accuracy from the deepest black to the brightest whites and colours, QLED TVs are lit by LED backlights that give 100 percent colour volume.
  • The most accurate HDR images can be delivered by QLED TVs thanks to their maximum peak brightness, which also comes with a 10-year warranty against screen burn.
  • QLED TVs have been created with technologies to assist in absorbing or diverting outside light to lessen reflections, making them usable in all lighting conditions.
  • OLED TVs are made of organic materials, and their pixels function independently of one another and individually light up depending on when they are needed.
  • OLED TVs don’t have a backlight, which contributes to deeper blacks that aren’t affected by light coming from the screen.
  • OLEDs can also support HDR, and since each pixel can be individually switched on and off, even in scenarios with rapid movement, the motion on the screen is smooth.
  • The sets are the thinnest available on the market because OLED screens don’t have a backlight.

 The Final Verdict

MicroLED won’t be a practical option for most people for a long time, and self-emitting quantum dots are still a way off. With the Sony A95K and Samsung S95B delivering great but not game-changing performances, QD-OLED TVs haven’t yet demonstrated that they are the best of both worlds. Therefore, a TV consumer in the here and now is forced to decide which mix of strengths and concessions best suits their taste because the Holy Grail of TV is probably still a long way off.

The QLEDs are undoubtedly brighter and more vivid than its OLED competitors, and they have impressively closed the gap in recent years regarding viewing angles and black depth. A recent development in that approach is Neo QLEDs with Mini LED backlighting.

Although OLED TVs don’t become as bright as QLEDs, their self-emissive qualities make for incredibly beautiful contrast, giving OLED a minor advantage in these areas.

Samsung sells a variety of QLEDs, and each model has unique features that vary from model to model. These major features include the backlight’s brightness and the number of dimming zones rather than processing. The greatest models must be chosen if you want the greatest dimming zones and the punchiest QLED.

The bottom line is that both OLED and QLED can produce excellent results, so it would probably be preferable to go for the best TV you can afford overall rather than narrowing your search to one technology.

Conclusion

Although each of these technologies is spectacular in its own right, and both provide excellent features,  I would prefer to choose a winner, and at the moment, that victor is OLED. It’s the highest picture quality money can buy with improved performance in the areas most viewers notice while watching TV shows and movies.

In terms of brightness, longevity, screen size, pricing, and lack of burn-in risk, QLED is superior on paper. It also has a longer lifespan than other LED technologies. OLED, on the other hand, is fantastic for gaming and may be better for your health. 

It also has a better viewing angle and deeper black levels. But it’s hard to pick between them because they’re both excellent. QLED is more versatile, but OLED technology shines when you can adjust the lighting in your space.

Frequently Asked Questions

How can I find the difference between OLED and QLED?

OLED is a technology that is fundamentally distinct from LCD, the most common type of TV. With the addition of a quantum dot film to the LCD “sandwich,” QLED is an adaptation of LED LCD. OLEDs have “emissive” pixels, which means they produce their own light. QLED, like LCD, is currently “transmissive” and depends on an LED backlight.

Is QLED more precise than OLED?

Due to the contrasts they provide, OLED displays provide the finest picture quality compared to QLED TVs. While some QLED and variables like dimming zones might lessen some quality discrepancies, there are many reasons why you should thoroughly investigate the specifications of the QLED TV.

Do OLED burn-in issues still exist?

OLED TV owners are now much less likely to experience screen burn thanks to ongoing advancements in OLED TV manufacturing. OLED burn in obviously still raises concerns for some people, and there are still sporadic reports of it occurring.

Why should I buy a QLED?

However, at their core, QLED TVs are simply standard LCD sets that have been enhanced with quantum dots to perform better than a standard LCD TV alone. This is true of every Samsung TV that carries the QLED moniker. It uses these quantum dots to offer much better picture quality than an LCD panel alone could offer.
