The battle of LEDs and LCDs is over. The new TV format war is between three new technologies: QLED, OLED, and MicroLED. It’s a confusing naming scheme, but the difference is actually easy to understand.

Here’s what you need to know first:

  • Samsung is the force behind QLED, which stands for Quantum Dot LED.
  • LG created OLED, which stands for Organic LED.
  • Samsung is also the force behind MicroLED.

As always, LED stands for light-emitting diode. In case there are any other terms you need to familiarize yourself with, we have a TV terms jargon buster guide.

It’s About Backlighting vs. Self-Lighting

Until now, LED TVs and LCD TVs What Is The Difference Between An LCD And An LED Backlit LCD Display? What Is The Difference Between An LCD And An LED Backlit LCD Display? This subject is complex because it’s simple. The differences between LCD and LED are subtle, which can make it difficult to understand the difference. It’s an important distinction, however, because it can significantly impact image... Read More were marketing jargon for different types of LCD. In an LCD TV, a single “pixel” cannot light itself. It requires backlighting by a panel of LEDs.

The crucial difference between QLED, OLED, and MicroLED is this backlighting:

  • Samsung’s QLED does not have pixels that can light themselves, so it is an extension of current LCD TV technology.
  • LG’s OLED has pixels that illuminate themselves, so it’s a new type of technology.
  • Samsung’s MicroLED also has pixels that illuminate themselves, so it’s a new type of technology, but slightly different from LG’s OLED.

Samsung QLED: LCD-LED in a New Avatar

Samsung QLED Graph

For years, regular LCD and LED TVs have used a series of thin layers from the backlight to the polarizer. Samsung has introduced a new layer in this series, which is the Quantum Dot filter.

This filter is unsurprisingly made of quantum dots, which are basically particles that take the incoming light from the backlight and turn it into simple RGB colors. After this, the colors travel further and interact with other layers to create the images that you see on screen.

But by simplifying to these basic colors, the color accuracy of those images is far better. Specifically:

  • The added quantum dot filter improves color accuracy by up to 90 percent from today’s LED TVs.
  • It also allows for up to 2,000 nits of brightness, which means you get better HDR performance.
  • Without each pixel being able to turn on and off, the black levels and contrast ratio remains the same as the best-quality LED-LCD TVs today.
  • Viewing angles are what you’d get on current TVs; they’re not as wide as OLED or MicroLED.

Note: Samsung and its quantum dot supplier Nanosys said they are working on QLED that emits its own light, removing the need for backlighting. This technology is expected sometime between 2021 and 2023.

LG OLED: The Best TV Display Tech Today

While Samsung focuses on QLED for now, LG has championed OLED technology. OLED displays are fairly common on smartphones, but it’s difficult to make them at the large size that a TV requires.

Samsung continues to make OLEDs for phones, but couldn’t manage to scale them up for TVs. LG used a different manufacturing method and achieved TV-sized OLED screens.

Now, LG’s OLED TVs are the gold standard. Yes, they are really expensive.

  • Each pixel of an OLED TV can glow or dim on its own, resulting in much better black levels and improved contrast ratio.
  • OLED TVs have excellent viewing angles and color quality. While they can’t get as bright as 2,000 nits, the HDR quality is fantastic nonetheless.
  • OLEDs have consistently topped the review ratings of CNET, which has the best TV-testing facilities and staff among all media organizations.

  • OLED TVs consume more power than QLED or LED-LCD TVs.

Sony OLED: Building on LG’s Success

After being on the fence for some time, Sony has thrown its weight behind OLED technology. Sure, LG manufactures the base OLED panel required for such TVs, but a lot more goes into making a good TV.

Once Sony gets the OLED panel from LG, it’s Sony’s job to fine-tune the other components that will ensure the OLED panel performs at its finest. Sony was renowned for picture quality from its famed BRAVIA engine on LED-LCDs. For OLEDs, Sony is launching a new processor, the X1 Ultimate. It hasn’t become available in any TV so far, and if I were you, I’d wait till it was.

Right now, Sony has only one new-generation OLED TV, the Sony A8F, which uses the previous-generation X1 Extreme processor. From demos at CES 2018, the X1 Ultimate is expected to deliver much better images, especially for HDR performance.

In summary:

  • Hold off on a Sony purchase for now. Wait for its new line of OLED TVs to hit the market.
  • The current OLED model, the Sony A8F, has got good reviews. If you’re a Sony fan and can’t wait for a new TV, go for it.
  • If the Sony brand loyalty isn’t important to you, LG has better OLED TVs at the moment.

Samsung MicroLED: The Future of TV Displays

The other big news from CES 2018 I Went to CES 2018 and It Was Quite Underwhelming I Went to CES 2018 and It Was Quite Underwhelming For the first time in its long history, MakeUseOf has made the journey to the Consumer Electronics Show (CES). We brought three of our finest (and me) along for the trip. Read More was Samsung’s new technology, MicroLED. And it made a bang with a gargantuan 146-inch TV that Samsung simply calls “The Wall”. MicroLED combines the best of QLED and OLED, while adding even more.

Like OLEDs, MicroLEDs have pixels that emit their own light. Each pixel is a combination of quantum dot red, green, and blue LEDs that can turn off or on individually. The end result is black levels, contrast ratio, and viewing angles of OLED, along with the color accuracy and brightness of QLED.

Samsung also says MicroLED TVs are modular, in that you can change the TV’s size. For example, “The Wall” is made up of 4-inch panels stuck together. You could potentially buy more 4-inch MicroLED panels from Samsung and increase the size of your TV, instead of buying a whole new TV.

But all these possibilities are way in the future. Right now, Samsung has not yet figured out how to decrease the size of these panels for a mass-market TV of popular 55-inch or 65-inch sizes. They only plan to release “The Wall” in 2018, and at an exorbitant price. It will take another 3-5 years, or maybe more, for MicroLED TVs for regular consumers.
