TVs are very important part of human life. Today we are going to see the differences between two types of advanced televisions technologies. They are known as OLED and QLED. So now we will see the differences OLED Vs QLED.

Let’s see the main differences between OLED Vs QLED.


In the topics below we will find the differences between OLED Vs QLED. Let’s go through these properties of OLED and QLED.





OLED means Organic light emitting diodes. On the other hand QLED means Quantum dot Light emitting diode.


Basically QLEDs are the same as traditional LCDs just renamed over by Samsung. This is just a business tactics to sell their products. It does have new quantum filter on top to make the colors brighter and stuff like that. But basically it’s the same as LCDs.

However OLED is completely a different technology made by LG. But today various companies are manufacturing these type of Television sets. Now they do add their own technology on top of it to make it work the basic difference.


Organic light emitting diode

It is the fact that each pixel in the TV is charged and light up individually. It can turn on and turn off whenever it needs to. This individual pixel lightning technology with organic light emitting diodes makes it special.

Based on these fundamental differences if you were to ask which one is better? The answer would vary depending on your situation.


What kind of room you’re going to be putting this TV. Now if you’re one of those people that just buy the TV for the usage of it and doesn’t really care about what kind of effects and differences these two technologies would have then it will not be beneficial for you.

But if you’re one of those people that really care about the details of how those TVs are going to be used in terms of where exactly in the house and what kind of room is it going to be placed in. And for what kind of stuff your TV can be used like it might be for sports, games, movies, serials, HD contents etc. Then this is how these two TVs differentiate between each other.

Type of rooms you are using also affects its performance. So if you have a cinema theater room or something like that in your house where everything is blacked out completely. Then all it is the way to go for OLED.

The reason for that is whenever the scenes have blacks in it those pixels would actually turn off to make it bright. The quality of videos and pictures will be very unique for you.

So on the other hand QLED does not work in this kind of situation because their blacks are actually not black they’re just similar to grayish color. But to a naked eye or a situation like that it might not make it a different.

 Honestly those kind of darker rooms are not available in every household. Hence the solution is QLED. So if you have a window or bright lights in the room, QLEDs are totally viewable without any problems.


OLED VS QLED Viewing Angle

Let’s talk about the viewing angle.

OLEDs are much better in terms of different angles viewing. Just because of the fact that their color variation does not change based on the angle that you’re looking from. So you can get the same colour from each part or corner of your room.

But on the other hand QLEDs that sense. They just let the light through them and they do change the colors based on the angle that you’re looking from. So if you’re in a room full of family members watching the TV from different angles the colors would be slightly different for each one of them.


Let’s talk about calibration

Calibration is a technology where you can change the colors off your TV based on the room. That it’s in it generally just brings down the color tones to their natural state to be able to see from a naked eye just so the picture itself can look more natural. It also adds more life to your TV.


Let’s do make it much easier. Now let’s talk about the image burn for both of these technologies.

In case of OLED TVs,If you’re using it for too long.

So if you watch certain channel with their logo at one side of the TV for a very long time every single day then these pixels would have a burn image on the screen. So after prolonged use of a same channel you can see its logo embedding in other channels content.

But in case of QLED TVs this problem is not found. And it tend to do it a lot more than OLED TVs.

But again these are extreme examples if you’re just using it for everyday just like a normal TV being used and you would not be having any kind of issues.


Generally QLED do come with much better warranties than OLED TVs.


OLED VS QLED Brightness

Brightness is more often used in marketing literature, refers to the emitted luminous intensity on screen.

It is measured in Candela per square meter (cd/m2). The higher the number the brighter the screen.

In case of OLED TVs the highest brightness can go around as about 800 to 850 cd/m2.

Where as in QLED TVs, it can go up to about 1500 cd/m2. So it can go very well  and very bright.

But even in normal watching situations the OLED TV that goes to about 800 to 850 units is good enough.

In brightness QLED TVs can go a lot brighter than OLED TVs. But even for HDR 800 to 850 users  there’s more than enough.


In case of OLED TVs you can get the best picture quality ever. Picture quality in terms of contrast, color and everything are good enough than other TVs.

In case of QLED TVs you can also get good picture quality. But again it changes as per viewing angle. The screen is more brighter than OLED TVs. Hence sometimes you may get “Light bleed effect”. In light bleed effect you will see slight haze around bright objects.

Advantages of OLED TVs:

  • No backlight required
  • Very thin transparent film than other monitos
  • Less power consumption than all monitors
  • Very high Contrast and real colour
  • Response time of 0.01MS
  • Refresh rate exceeding 1KHZ (1000hz) possible
  • Viewing angles
  • Flexible and transparent

Disadvantages of OLED TVs:

  • Organic materials used in OLED display degraded over time, like other organic material
  • Blue emissive pixels degraded more rapidly than their red and green counterparts, which leads to colour balance issues
  • Image retention issue, problem arises in static content display for an extended period. This problem can not be noticed in moving contents like TVs but for PCs it will be of serious concern.

Advantages of QLED TVs :

  • Resists moisture
  • Products will have long life span
  • Cost effective
  • Available in higher display sizes
  • It is thin and light weight
  • Good switching On/Off speed
  • Brightness is more
  • Low power consumption
  • Not susceptible to image burn

Disadvantages of QLED TVs :

  • Blue color is less saturated
  • Viewing angle is not so good. Best viewing is dead center.
  • Quality of the picture changes with viewing angle change
  • Light bleed effect. Because of this you will see slight haze around bright objects.
  • It doesn’t produce light by themselves. Hence Backlight unit is required.

And just to repeat myself OLED TVs have much newer technology where each pixel is turned on and off based off of the information that’s given to it. Their darks are completely dark because the pixel is completely turned off.

They’re very easy to calibrate. They’re not good with too much of a bright room or picture. If used for too long they will have burn outs on the screen and they do have edges much thinner and completely flushed.

On the other side QLED are same as LCDs. They are much brighter in color and they work really well in brighter rooms as well. They change picture color based on the angle that you’re looking from and the calibration of these TVs is a bit tedious than older TVs.

Since all of these amazing companies related to TV market are always looking for ways to advance their technologies.

Make sure that you do your own research on a specific model that you’re about to purchase before making the final purchase.

Now after reading this article OLED Vs QLED, I think all your doubts on QLED and OLED TVs might be cleared. So choose smartly and wisely.

Have a great day.
