QLED vs. OLED

One letter really changes what you see

Buying a TV can be confusing. The two types you’ll find are QLED (Quantum Dot LED: LED-backlit LCD TV with a layer of quantum dots) and OLED (Organic LED or Organic Electroluminescence; no LCD is used).

QLED and OLED TVs have a lot in common. In general, factors such as screen resolution (1080p, 4K, 8K), support for specific HDR formats, smart TV technology, and form factor (such as flat or curved screens) vary by manufacturer and model.Regardless of the LED technology used to display the image

QLED is the marketing label used by Samsung, TCL and others to brand quantum dot TVs. Other labels include Color IQ, QD, QDT, Quantum (Vizio) and more.

Here, we take a look at how the two technologies differ in how they affect your TV viewing experience.

general results

QLED

  • Best for gamers and people who mostly watch news and TV shows.

  • It works well in bright light.

  • Available on smaller screens.

OLED

  • Best for movie fans and those who appreciate deep, rich blacks.

  • Perfect for dimly lit or light-driven viewing environments.

  • Thinner and lighter, but offers a larger screen size.

Your best choice among TVs depends a lot on your viewing habits. If you’re using your TV for gaming, watching TV, and news that doesn’t require the pure blacks that more art such as movies might require, then QLED is perfect for you. If you’re watching your TV in low light, OLED produces the picture quality and depth you’ll appreciate.

Under the Hood: How They Work

QLED

  • LED backlight or edge light provides a light source that passes through the LCD chip to create the image (LED/LCD TV).

  • A layer (flake) of quantum dots is placed between the backlight and the LCD layers (this is where the Q comes from).

OLED

  • Diodes use organic compounds that are pixelated and placed on top of the panel layers to create images.

  • Diodes glow when charged. They do not require an additional light source (backlight) to produce the image.

  • OLED TV screens are thinner than traditional LCD, LED/LCD and plasma screens.

QLED and OLED are very different in the underlying technologies that provide lifelike images on the screen.

QLED TV

Quantum dots are artificial nanocrystals that improve clarity and color performance. When a light source hits these points, each point emits a color with a bandwidth determined by its magnitude. Large dots glow reddishly, and progressively smaller dots tend towards green. Nanocrystals are usually placed in layers called QDEFs (Quantum Dot Enhancement Films), as shown in the image below.

Image quality: seeing is believing

QLED

  • Wider, more saturated color gamut (range) than other technologies.

  • Suitable for high brightness without losing saturation.

  • Absolute black cannot be produced because the LCD chip cannot be turned on and off, only dimmed. Even in dark scenes, there is always some light leakage around the LCD pixels.

  • Blur and color shift at wide viewing angles.

OLED

  • Best suited for low light or controlled light environments due to its lower light output.

  • Pixels can be turned on and off individually, enabling OLEDs to produce absolute blacks and near-perfect screen uniformity.

  • Blur and color casts are minimal at wide viewing angles.

  • If the static image is displayed for a long time, it is prone to burn-in.

Both technologies produce sharp, true-to-life images, but work differently when it comes to color and light. QLED offers a wider color gamut than OLED, maintaining color depth even when the screen is lit. However, it cannot produce true black.

Even from a certain angle, OLED produces deep, deep, true blacks with consistent color. However, this loyalty comes at a price. OLED can easily burn out if the same image is displayed for a long time.

Price: How much do you pay?

QLED

  • Not so expensive.

  • 4K games range from $800 (43 inches) to $6,500 (82 inches), and 8K games range from $5,000 (65 inches) to $15,000 (85 inches).

OLED

  • More expensive.

  • 4K gaming in the $1,600 (55-inch) to $13,000 (77-inch) range; LG’s 88-inch 8K TV or its upcoming 4K rollable OLED TV haven’t been priced yet.

Generally, you’ll pay more for an OLED TV, but prices vary based on time of year, promotions, and bundles. As with most technology, you can usually expect prices to drop as new models, screen sizes, and technologies hit the market.

Samsung is the leading manufacturer of QLED TVs, followed by Vizio for the US market. TCL offers QLED TVs in Asia and some international markets. LG is the leading OLED TV maker in the US, followed by Sony. Panasonic, Philips, Loewe and Bang & Olufsen all sell OLED devices in Europe and other select markets. Hisense, Skyworth and Changhong are mainly sold to the Chinese market.

All OLED TV manufacturers use displays from LG Display.

Form Factor: Collection Aesthetics

QLED

  • Screen sizes range from 43 to 85 inches.

OLED

  • Screen sizes range from 55 to 88 inches.

  • Thinner than a QLED TV, it can be rolled up like LG’s upcoming 65-inch model.

Both types of TVs come in different sizes. OLED TVs are thinner and lighter than their QLED counterparts, leading to exciting innovations such as LG’s upcoming Rolling Shutter TV.

Final verdict: it all depends

QLED and OLED TVs are evenly matched in terms of pros and cons.

Given the cost difference, if you watch mostly news and TV shows, or if you’re a gamer who watches a lot of static images such as news stickers, station logos, scores, and status boxes, then a QLED TV is the best choice. If You’re looking for and prefer a screen smaller than 55 inches in a bright room, and QLED is also a great option.

If you mostly watch movies and streaming content, are picky about the deepest blacks, watch in dim or light-controlled rooms, and are somewhat energy-conscious, OLED is the way to go.

Before deciding which one to buy, take a look at QLED and OLED TVs from different manufacturers.

Appendix: Looking to the future

Whether QLED and OLED TVs are as popular as traditional LED/LCD TVs will depend on manufacturers’ ability to reduce production costs, drive consumer preference for screen size, and continually improve performance.

Emerging technologies also affect popularity. For example, Samsung and other developers are working on a solution that combines quantum dots with OLEDs, known as QD-OLEDs, for better color and brightness performance without the shortcomings of current QLED and OLED TVs. Another solution from Samsung is microLED TVs, which allow buyers to create custom screen sizes and resolutions by assembling display modules.

QLED vs. OLED

A single letter really changes what you see

Shopping for a TV can get confusing. Two types you’ll encounter are QLED (quantum dot LED – LCD TV with LED backlight and quantum dot layer) and OLED (organic LED or organic electro-luminescence – No LCDs used).

QLED and OLED TVs have much in common. Generally, factors such as display resolutions (1080p, 4K, 8K), specific HDR format compatibility, smart TV technologies, and form factors (for example, flat or curved screen) vary by manufacturer and model, regardless of the LED technology used to display images.

QLED is a marketing label that Samsung, TCL, and others use in branding quantum-dot TVs. Other labels include Color IQ, QD, QDT, Quantum (Vizio), and similar.

Here, we take a look at how the two technologies differ in ways that can affect your TV viewing experience.

Overall Findings
QLED

Best for gamers and those who watch mostly news and TV shows.

Performs well in bright light.

Available in smaller screens.

OLED

Best for film aficionados and those who appreciate deep, bold blacks.

Well-suited to dimly lit or light-controlled viewing environments.

Thinner and lighter, but available in bigger screen sizes.

Your best choice in a TV depends largely on your viewing habits. If you use your TV for gaming and watching TV and news—content that doesn’t demand the true blacks that more artful productions such as movies might demand—a QLED would work well for you. If you watch TV in low lighting, OLED will produce the image quality and depth you’ll appreciate.

Under the Hood: How They Work
QLED

An LED back or edge light provides the light source that passes through the LCD chips to produce an image (LED/LCD TV).

A layer (sheet) composed of quantum dots (that’s where the Q comes from) is placed between the backlight and LCD layer. 

OLED

Diodes employ organic compounds that are formed into pixels and placed on a panel layer to create images.

Diodes produce light when electrically charged. They don’t need an extra light source (backlight) to produce images.

OLED TV screens are thinner than traditional LCD, LED/LCD, and plasma screens.

The underlying technology that brings realistic images through your screen differs drastically for QLEDs and OLEDs.

QLED TVs

Quantum dots are artificial nanocrystals that enhance brightness and color performance. When a light source hits the dots, each one emits a color of a bandwidth that’s determined by its size. Large dots emit reddish light, and progressively smaller dots skew towards green. The nanocrystals are commonly placed on a layer referred to as QDEF (Quantum Dot Enhancement Film), as illustrated below.

Nanosys OLED TVs

OLED technology creates images from pixels generated by organic compounds without needing an extra backlight, as illustrated below.

LG Display Picture Quality: Seeing Is Believing
QLED

Wider, more saturated color gamut (range) than other technologies.

Capable of high brightness without losing saturation.

Can’t produce absolute black because LCD chips can’t be turned off and on, only dimmed. There’s always some light leakage surrounding LCD pixels, even in dark scenes.

Color fading and shift at wide viewing angles.

OLED

Better suited to dimly lit or controlled-light environments because of lower light output.

Pixels can be turned on and off individually, which allows OLED to produce absolute black and have almost perfect screen uniformity.

Minimal color fading and shift at wide viewing angles.

Susceptible to screen burn-in if static images are displayed for too long.

Both technologies produce sharp, realistic images, but they perform differently with regard to color and light. QLED delivers a broader range of colors than OLED and retains color depth even when you brighten the display. However, it can’t produce a true black.

OLED produces deep, dark, true blacks with even color, even when viewed at an angle. Such fidelity comes at a cost, though. OLEDs are susceptible to burn-in if the same image is displayed for a long time.

Prices: How Much Will You Pay?
QLED

Less expensive.

Range from $800 (43 inches) to $6,500 (82 inches) for 4K sets, and $5,000 (65 inches) to $15,000 (85 inches) for 8K sets. 

OLED

More expensive.

Range from $1,600 (55 inches) to $13,000 (77 inches) for 4K sets; prices are not yet available for 88-inch 8K sets or LG’s forthcoming 4K roll-up OLED TVs. 

Generally, you’ll pay more for an OLED TV, but prices vary depending on the time of year, promotions, and bundling. As with most technology, you generally can expect prices to go lower as new models, screen sizes, and technologies appear on the market.

Samsung is the primary maker of QLED TVs, followed by Vizio for the U.S. market. TCL offers QLED TVs in Asian and some international markets. LG is the primary manufacturer of OLED TVs available in the U.S., followed by Sony. Panasonic, Philips, Loewe, and Bang & Olufsen sell OLED sets in Europe and other select markets. Hisense, Skyworth, and Changhong sell mainly in the China market.

Taking cost differences out of the mix, a QLED TV is better if you watch mostly news and TV programs, or if you’re a gamer who sees a lot of static images such as news tickers, station logos, scores, and status boxes. QLED is also a good choice if you watch in a brightly lit room and prefer screen sizes of less than 55 inches.

OLED is the best choice if you watch mostly movies and streaming content, are picky about getting the deepest blacks, watch in a dimly lit or light-controllable room, and are somewhat energy-conscious.

Check out both QLED and OLED TVs from different manufacturers before deciding which to buy.
Addendum: Looking to the Future

Whether QLED and OLED TVs become as popular as traditional LED/LCD TVs depends on the makers’ ability to lower production costs, make screen sizes consumers prefer, and constantly improve performance.

Emerging technologies can affect popularity, too. For instance, Samsung and other developers are working on a solution that combines quantum dots with OLED (dubbed QD-OLED) for better color performance and brightness without the drawbacks of current QLED and OLED TVs. Another solution from Samsung is microLED TVs that allow shoppers to create custom screen sizes and resolutions by assembling display modules.
