OLED vs QLED: Basics of Them

What is QLED?

QLED stands for Quantum dot Light Emitting Diode. It is similar to a common LED display, which means it has a liquid placed between polarizing material sheets. When electricity is passed, the image is created through it. Secondly, there is backlighting, which consists of an array of LEDs to illuminate the screen. The difference is that it contains an additional layer of quantum dots to improve color and brightness.

What is OLED?

OLED stands for Organic Light Emitting Diode. It works on a technology similar to an LED display. It also has a special liquid to create the image.
However, it does not contain a separate backlighting system. There are no LEDs in the background. Instead, each pixel is self-illuminating. Each pixel emits the light needed and creates a beautiful colored image.

OLED vs QLED: Pros and Cons

Pros and Cons of OLED

Pros:

• There is no backlighting in OLEDs, so they are quite thin and slim. Their appearance attracts attention.
• The response time of OLEDs is incredible. They are known for higher refresh rates.
• The color quality of OLEDs is amazing. It offers excellent color contrast ratio and black levels.
• The viewing angle of an OLED is wide, so you get to see true colors wherever you sit.

Cons:

• OLEDs have burn-in issues
• The life of OLED displays is shorter
• They are a bit more expensive compared to QLEDs

Pros and Cons of QLED

Pros:

• QLED offers better brightness due to the quantum dot layer
• No burn-in issue and the display lasts longer
• Offers excellent performance in bright rooms and areas
• Vivid and accurate colors even at high brightness

Cons:

• Due to the extra layer, the display is a bit thick
• It consumes more power compared to QLEDs
• Halo-effect is a common issue with QLED displays
• Doesn’t offer perfect black performance as OLEDs

QLED vs OLED: What's the Difference?

Technology and Light Source

Both QLED and OLED are based on LED technology. However, QLED contains an additional quantum dot layer along with backlighting. On the other hand, OLED does not require backlighting as its pixels are self-illuminating.

Black Levels and Contrast

OLED has no comparison when it comes to black levels and contrast. It offers infinite contrast ratios and perfect black levels.

QLED offers suitable black levels and contrast ratio. It’s good but not better than OLEDs.

Brightness

QLEDs have a quantum dot layer that brings more brightness. They can work in bright areas perfectly.

In contrast, OLEDs are also good in brightness due to self-illuminating pixels. But they are better than QLEDs.

Color Accuracy and Range

QLEDs are superior in color. It is because of the quantum dot layer, which emits precise colored light. The color accuracy is top-notch.

OLEDs are also good in color and offer excellent accuracy. However, QLEDs are superior.

Viewing Angle

OLEDs are the winners in viewing angles. Due to the self-illuminating pixels, they offer true colors at a wide range of viewing angles. You can watch from any angle without worrying about color shifts.

QLEDs have a decent viewing angle. But they compromise on the color at certain angles.

Burn-in Risk and Life Span

There is no burn-in risk in QLEDs, and they last longer.

But OLEDs are prone to burn-in. Their pixels have a higher risk. Moreover, their life is shorter as the pixel performance deteriorates over time.

QLED vs OLED: Which One to Choose?

OLED vs QLED TV

OLED and QLED are both incredible choices for TVs. They both offer a mesmerizing experience. However, they are meant for different purposes.

OLED is a great choice when color contrast and black levels matter a lot. You can install them at home and enjoy lovely colors.

QLED is the best option when you want extreme brightness and color volume. They are more affordable and tend to last longer.

OLED vs QLED for Game

Gamers care more about the seamless experience and immersive display. OLED is excellent because it offers infinite contrast and a perfect black level. Secondly, its response time is better, which gamers love. They prefer higher refresh rates to enjoy games without any lag.

QLED also works great. They are not as fast as OLEDs in response time but also not slow. They have better brightness and color volume. So if you are playing games in a bright area, QLED is the best choice.

UHD vs QLED vs OLED: What's the Difference?

What is UHD?

UHD means Ultra High Definition. It refers to a display resolution of 3840 x 2160 pixels, which is also known as 4K. It is not a display technology like QLED and OLED. It only refers to the number of pixels on the screen. That said, OLED and QLED displays can be UHD if they have the required resolution.

Comparison Table

We cannot compare UHD with OLEDs and QLEDs because they are resolution standards. Let’s have a quick comparison of the OLED and QLED technology.

FAQs

1. Is QLED or OLED better?

Both are excellent display technologies. But you have to choose according to the application. OLED is better in contrast ratio and black levels. And QLED is better in brightness and color volume.

2. Which is better LED vs OLED vs QLED?

For normal use and affordability, LED is definitely better. If you want a better contrast ratio, black levels, and colors, you can switch to OLED. If brightness and color volume are preferred, you can choose QLED.

3. Do OLED or QLED TVs last longer?

QLEDs last longer because they do not have burn-in issues. They use the traditional backlighting as in LED displays. OLEDs have a suitable lifespan, but not better.

Conclusion

QLED and OLED are both popular and preferred display technologies these days. You will find TVs, monitors, gaming screens, and other displays using them. However, you have to choose based on the application and your preferences. We have compared both technologies in detail to give you a better idea and help you choose the right one according to your needs.
