QLED vs. OLED | What’s the Difference & Which to Go For?

As televisions have become ever more extensive and more high-resolution, the two main types of TV technology have become increasingly important: QLED tv and OLED tv. The two are pretty different, but it's essential to understand before purchasing.

QLED uses a layer of tiny LED lights to create the image on the screen. Each light is responsible for creating one pixel in an image, which leads to brighter colors and more detailed photos. However, QLED televisions are also quite large since they need ample space for these tiny LEDs underneath each pixel.

Comparing OLED vs. QLED TVs

OLED TVs, or Organic Light-Emitting Diode TVs, are a relatively new display technology that uses a light-emitting diode for each pixel. It doesn't require an LED backlight. They provide better contrast and black levels than LCD or QLED TVs.

QLED TVs, or Quantum Dot Light-Emitting Diode TVs, are newer TV tech.

QLED TVs

QLED televisions are upgraded versions of the LCD panel or QLED TVs with better color vibrancy and brightness and more detailed pictures due to bright LED lights. It is essentially an LCD TV with quantum dots - microscopic semiconductor crystals that shine light in new and exciting ways. These crystals emit specific wavelengths of light when excited by electricity or other forms of energy.

By carefully controlling the size, shape, and positions of these crystals, manufacturers can control the wavelengths of light emitted. It allows for more subtle colors and better potential brightness. In essence, they are a variant of LCD TVs with quantum dots that enhance how bright the screen is and how many colors it can show.

Features

  • More detailed colors and higher contrast ratios than QLED TVs
  • QLED TVs can achieve deeper blacks.
  • LED lights underneath each pixel produce bright pictures that don't require backlighting as LCDs do.
  • It can be pretty significant because of the space required for all those LEDs. However, they are much thinner than their LCD counterparts.
  • It varies from model to model. Some QLED TVs are incredibly bright, while others have poor picture quality due to their manufacture.

Pros and Cons of QLED

Pros:

  • QLED TVs have a fast response time, making them better at playing video games without ghosting.
  • Quicker changing of screen colors due to their faster response times. There's no delay, so there isn't motion blur either.
  • Higher brightness levels than OLED screens can reach. It isn't by much, though, so they're about as bright as OLED screens when it comes to HDR content.
  • QLED TVs have a wider color gamut, making them better at displaying vibrant colors.

Cons:

  • QLED TVs tend to run a bit warmer than OLEDs because they use LEDs for backlighting.

OLED TVs

OLED TVs, or Organic Light-Emitting Diode TVs, are a relatively new display technology that uses a light-emitting diode for each pixel. It doesn't require an LED backlight and instead uses OLED panels. They provide better contrast and black levels than LCD or QLED TVs.

When it comes to the future of TV, OLED is the way to go. It's a newer technology with better picture quality and durability. It's also more expensive, which can be a drawback. However, the TVs are also getting cheaper with each new model released. 

OLEDs are more costly than QLED due to how new they are and how much R&D has gone into making them work properly. It has more detailed colors and higher contrast ratios than QLED TVs.

Features

  • A wide viewing angle
  • The lack of a backlight makes viewing angles better because there is nothing to interfere with the picture.
  • Thin and flexible form factor
  • Short response time ( microseconds)
  • Very high contrast ratio

OLED is the future of TV technology regarding image quality and how it works. It has no backlight, allowing for better viewing angles that don't interfere with the picture at all. OLED technology is excellent for dark rooms and when it comes to watching movies, but when you watch TV with the lights on, it might make the picture look dull and washed out.

Pros and Cons of OLED

Pros:

  • Perfect blacks, thanks to the infinite contrast ratio. The way they're able to produce perfect blacks without compromising other aspects is what makes the difference between OLED and LED/QLED screens so obvious.
  • Better at displaying HDR content due to their wide brightness range. No matter how dark the movie scene gets, an OLED TV will make it look as bright and vibrant as possible.
  • The colors and brightness remain accurate at all times, no matter the viewing angle. There's only a very slight degradation of image quality when moving to the side.
  • Greater sense of depth and realism for 3D movies due to their infinite contrast ratio and wider color gamut.

Cons:

  • Since it's not popular, you may have a challenge finding it in the market

Main Differences Between OLED and QLED

  • QLED TVs are upgraded versions of the LCD panel with better color vibrancy and brightness, while OLED TVs are newer TV technology with better picture quality. However, they are both different in many ways.
  • LED lights underneath each pixel produce bright pictures that don't require backlighting, like LCDs in QLED TVs, whereas OLEDs have no backlight. They are more expensive than QLED due to how new they are and how much R&D has gone into making them work properly, while the features of QLED TVs include: More detailed colors and higher contrast ratios than QLED TVs.
  • QLED TVs can achieve more profound blacks, whereas OLED televisions are better for dark rooms and watching movies.
  • QLED TVs are more expensive than QLED due to how new they are and how much R&D has gone into making them work properly, while OLED is the future of TV technology regarding image quality and how it works.

LED vs. QLED vs. OLED TV: What’s the Difference?

Because of their affordability and good picture quality LED TVs are a popular choice for many people. However, these TVs use LED backlights that can sometimes make the picture look washed out.

OLED TVs are known for their superior contrast ratios and deep blacks, making them better at displaying movies with dark scenes. On the other hand, QLEDs have slightly lower response times.

QLED TVs are also at par with OLEDs regarding brightness range. As such, they're just as good at showing bright images of HDR10 content as OLED screens, if not better.

Regarding price, QLED TVs are usually more expensive than OLED TVs. It's because they're still new to the market and aren't as refined as OLEDs just yet. However, since they're on the same level regarding brightness and contrast ratios, this tends to even out with time. Shortly, QLED TVs might be even less expensive.

Factors to Consider When Buying QLED vs. OLED TVs

Below is a list of factors you should consider before buying an OLED or QLED TV:

HDR Compatibility

With each successive release, standards for what makes a TV "HDR-compatible" have become more stringent. You must do your research to avoid getting ripped off by shady retailers trying to make a quick buck from uninformed consumers. To ensure your new QLED or OLED TV is compatible with the latest standards, check if it has an Ultra HD Premium certification.

Viewing Angle

The view angle for OLED TVs isn't that good, especially regarding the colors. The image gets a bit more washed out when you sit off-axis. The QLED's view angle is better than that of OLED TVs. You won't notice a difference when both are set up side-by-side, but it's primarily functional in theaters where people tend to sit all around the room.

Response Time

For the most part, QLED and OLED are both similar in this aspect since they both use different technologies for their pixels. A QLED TV has a faster response time than an OLED because it works in microseconds. 

Other factors that you need to consider include :

  • Price- QLED TVs are usually less expensive than OLED TVs because they are new. OLED TVs are also constantly getting cheaper with each new model released.
  • Durability- QLED TVs have better durability overall because no specific TV part can break easily during regular use. On the other hand, OLED screens are vulnerable to burn-in if a static image is shown for extended periods.
  • Brightness- QLED TVs can get much brighter than OLED TVs, especially in HDR10 content due to the brightness range. However, OLED screens are generally better at producing deep blacks and thus have better contrast ratios.
  • Contrast Ratio- OLED TVs offer better contrast ratios than any LCD TV, including QLED TVs. They're far superior to other TV technologies display-wise.
