OLED VS QLED: Difference Between OLED And QLED

Are you planning to bring a new television to your home? Shopping for a TV can be intimidating for you. The reason is, the advancements in TV technologies are growing day by day. Ultra HD, 4k, and 8k TVs are becoming popular, HDR is readily available, and streaming nowadays is like shooting fish in a barrel with these TV technologies.

However, at times it can be quite baffling too. If you’re in the market, you have likely heard about the battle between two premium TV technologies, i.e., OLED VS QLED. So, what is the specialty in them that has made it a subject of great discussion in the market?


Don’t worry about this. In this article, we will talk about the key parameters of both TV technologies if you are in a dilemma about which one is better between OLED Vs. QLED TV? Your all concerns regarding that will vanish after reading this article.

What is OLED ?

OLED stands for the Organic Light Emitting diode, is often familiarized as the flagships of the LG brand. If you are in a dilemma, what is the difference between LED TV and OLED TV? Or does it have any new specialty that makes it ‘OLED,’ then you are thinking right to some extent?. They are just a new version of LED TVs with an organic component inbuilt into them. However, a slight difference is, their displays are wildly different from LED TVs.


It uses different panels to generate and illuminate the picture on the screen. OLED themselves produces each pixel in a panel. Hence, it determines the color, and that causes it to produce light. Generally, displays in OLED TVs are kind of similar to now-defunct plasma TVs. They are capable of generating a picture without an external source of illumination.

The contrast is good. Ensure deep blacks and realistic colors. OLED TVs generally do not need backlights. They are thinner in shape, and bezels are narrower compared to QLED TV or other TV technologies. And, that can be treated as a great difference between OLED and QLED TVs.


OLED TVs are king in TV technologies as their black levels are superb. However, it has slight issues in terms of brightness. Compared to other TVs like QLED or LED and HDR, it doesn’t achieve the apex of brightness level. But you don’t worry about the image quality. You can view through different angles and with better picture quality.

  • They are lighter and thinner
  • Comes up with self-emissive pixels
  • Refreshes at a faster rate (0.001ms)
  • Judder and blur-free picture quality
  • Have more convincing blacks
  • Low power consumption
  • Available in limited sizes
  • Quite expensive
  • They have slight issues in brightness

What is QLED ?

When it comes to TV technologies, you can’t ignore QLED TVs from them. They are generally considered as middle-ground TV between LED and OLED TVs. You know, OLED comes up with an organic Light-emitting diode technology, whereas the quantum-dot filter technology is used in QLED TVs. This is a common difference you can see in these two premium TV technologies.


Quantum-Dot filter, which has been introduced in LED, helps to produce a glooming color. However, QLED TVs have a high brightness level compared to LED and OLED TVs. Though they have an optimum level of brightness quality, they are short in contrast levels and deep blacks that are superb in OLED TVs.

Samsung is the company that makes premium series of QLED TVs. These are generally not used in smaller TVs and available only from 43 inches, i.e., starting point for this type of screen. OnePlus, TCL, Vu is a few of the other manufacturers of QLED TVs in India.

  • Comes up with a brilliant whites
  • It is ultra-bright up to 2,000 units
  • It offers a variety of screen sizes
  • Slow refresh rate
  • Less convincing blacks
  • Sometimes it is overly bright.



We will evaluate the comparison between the OLED and QLED based on the following parameters:

  • Black Levels and Contrast
  • Brightness
  • Color space
  • Size
  • Power consumption
  • Price
  • Lifespan
  • Eye comfort
  • HDR

Black levels and Contrast

If we talk about the black levels and contrast, OLED comes out to be in a top position, as it has the ability to get into black when it needs to. OLED can switch off individual pixels as and when required. So a perfect black color can be achieved. However, QLED still depends on backlighting. So Black becomes somewhat greyish.


When it comes to brightness, QLED wins the user’s heart with its extraordinary brightening quality. Unlike LEDs, they use separate backlights, and that made their brightness incredible While. On the other hand, OLED TVs are not capable of producing the same amount of light.

Color space

According to Samsung, QLED TVs ensure high accuracy in terms of colors, offer excellent color brightness and color volume. Samsung also claims that their QLED TVs can produce 100% sRGB, whereas OLED TVs can only go up to 70% sRGB. But we can’t deny the fact that OLED also delivers superb colors in everyday viewing situations. So, here we can say this battle is drawn.



No doubt, if you are looking for a TV with HDR ( High Dynamic Range), QLED TV is the best. The brightness can go all the way up to 2000 Nits. This is what a human eye can withstand. Even the color accuracy and contrast are a bit high in QLED with HDR.


In contrast, OLED gives you an optimum level of brightness with perfect color accuracy and detail. So it’s again a consumer call which one is preferable for them.


Looking at the sizes of TV, it is seen that OLED screens are limited to a max of 55 inches, whereas the QLED TVs are less expensive, and they generally produce screens of various sizes. Their starting size of screens is from 43 inches and goes up to 85 inches and even beyond.

Viewing Angle

If you are watching on a QLED screen, the best viewing angle for you is dead center. And, as you move side to side and up to down, color brightness and contrast gradually diminish. On the other hand, in OLED screens, you are free to view even at drastic angles. The maximum angles range up to 84 degrees. So, if you plan a screening of a movie with friends or family, OLED is the best TV option for you.

Power consumption

QLED panels generally do need a super-bright backlight. You know what backlights consume a great amount of heat and to produce heat we need more power. So QLED consumes more power. Hence, we can say, OLED is good in terms of energy efficiency.

One more thing that aids in low power consumption in OLED TVs is OLED TV pixels work. OLED TV pixels can turn themselves off individually whenever it is required. So even if your TV is turned ON, there might be many pixels that are switched off. This way, OLED saves more power


Pricing is something that is the real concern of people. And, if we talk about the cost of both OLED and QLED, both cost like a bomb.


Lifespan depends on certain factors, whether it has a source of backlighting or not. So, if we take this aspect, we can say that QLED has a high life, as it has a backlight source. On the other hand, OLED depends on individual pixels. So even if there are some dead pixels, the TV will still work for you.


Eye comfort

It has been observed that OLED offers greater eye comfort than any other TV technology. The reason is, it produces less blue light compared to other TV technologies. And we know that blue light is harmful to human eyes. So in the race of OLED vs. QLED in terms of eye comfort, OLED has the edge.

Conclusion: QLED Vs OLED

In a nutshell, we can say that it totally depends on your taste whether you choose an OLED TV or a QLED TV. If you prefer to have a TV with a great display color and image screen, OLED is the best for you.

However, if you are looking for a TV having less burn risks and good display size, go for QLED Tv.
