QLED and OLED these technologies have nothing in common except for their names. There are completely different from each other. Whenever you want to purchase a new LED TV, you may get confused in these two names. Simply they are just names of the display technology that you might get on your TV.

IT is just like the war that we have witnessed between LCD and Plasma. They both have some of the best products in the market, but they also have some of the weaknesses and strengths accordingly. The two biggest brands of this industry Samsung and LG are using one of these technologies and having an amazing response from their customers.

Samsung is the user of QLED technology and on the other hand; LG uses the OLED technology in its TVs. These both are the premium display technologies.

What is QLED?

QLED means Quantum Light-Emitting Diode. this technology was first brought up by Samsung and other companies are using it as well. It is nothing but using quantum dots on the LCD panel. In this technology, the panel of TV remains the same as LCD’s has.

Quantum dots produces the light by the LED’s, it comes from the LED and sits behind the LCD panel. The number of LED lights behind the panel is not the same in all TVs, some have few LED lights and some have more. It’s a clever system, before coming directly to your eyes these lights have been filtered by the LCD panel’s shutters.

They allow just the right amount of light to get passed through panels. The light travels through a lot of layers inside the TV before passing through an LCD layer.

Samsung uses this technology as well as others too like TCL, Visio but they do not call it QLED TV’s.

What is OLED?

OLED simply means Organic Light-Emitting Diode. It simply states that every teeny tiny pixel has its own light and capable of producing its own light and color for the TV. It refers to the fact that it does not require light from the end to transmit the colors as it can do both itself.

OLED TVs produce amazing dark colors especially the black one; as it does not require to dim the light from the back end. It will just turn the pixel off for the black color and that looks great on TV.

Only LG company is making its own OLED Panels that is why they are selling LG’s OLED TV. Other than this they are also selling the panels to other companies like Sony. This technology is also referred to as emissive display technology.

QLED vs. OLED

QLED and OLED are two different things but these two are the only technologies that are used by most of the brands in this industry. Let’s compare them in different aspects and in detail, without wasting any time lets begin.

Levels of Black and Contrast

Contrast is the difference between the darkest color of TV and the brightest color of TV. This is the biggest advantage that OLED TVs have it can just turn its pixels off to show the pitch-black color and the difference between both becomes more enhanced.

To maintain the level of contrast QLED has to turn its light dim from the first layer; it’s like blocking some of the pixels to emit the light which is very hard to do.

The primary goal these days for any TV maker is to put as many pixels on the TV as possible. When it comes to producing the black color; the TV must be capable of blocking or turning off those many pixels. It is hard to block the light from that many pixels; and better to just turn off some which we do not need and they will produce the best black and contrast level in the picture.

Brightness

In the case of brightness, QLED TVs have an advantage over OLED TVs. QLED TVs use separate backlights and these backlights can be made incredibly bright. This is the advantage as they do not have to be relied upon each and every pixel to produce its own light.

OLED TVs light-emitting pixels cant produce the same amount of light. It is not a problem in the darkroom or where the natural light is also low. But in rooms or places where natural light is good or the rooms are well lit QLED TVs are a better option.

Color Space

When it comes to color accuracy, color brightness, and color volume there might be an advantage in QLED over OLED as it has a brighter quality. But both the TVs have the options of their products in 4k and 8k as well; so there is not a major difference in colors in both of them We can make this a draw between both of them.

Size

When it comes down to the size of the TV, QLED has so many options but on the other hand, OLED TV has a few options like from 55 -65-77-88 inch size. You need to spend a few lakhs to get an OLED TV of big size.

The QLED on the other hand, you can get from 43 inch to 98 inches of TV and they can even get smaller as well. OLED TVs are super expensive and in large sizes only.

Screen Burn-in

Screen burn-in or ghosting can happen on any TV, theoretically. It basically caused by the incessant use of the same pixels on TV. For example, you are watching Sony TV for few days; and do not change the channel in few days, just watched the same channel. When you will change the channel after few days there might be a possibility that the logo of a channel might get printed permanently on your TV screen.

OLED TVs are more likely to be susceptible to this phenomenon than QLED TVs.

Response Time, Input Lag and Refresh Rate

Response time is the time taken by one pixel to shifts its state from one state to another. The faster the response time, the quality of the image will be more good. QLED TV response time is between 2-8 milliseconds and OLED TV response time is 0.1 millisecond. So, in this case, OLED TVs are good.

Input Lag is the delay time between taking an action or seeing the result on the screen. Like you pressed a button and in how much time TV starts to show you the result. It really concerns the gamers only as of the users who are not playing high-end games on their TV have nothing to do with this.

Both QLED and OLED TVs have a similar input lag if you just turn off any other task that is running on the back end of the TV.

The refresh rate is the rate at which the number of times TV refresh itself to show you the picture. It is also a concern for gamers, to choose the 60Hz or 120Hz refresh rate on TV. For gamers, users should choose the model of VRR that is a variable refresh rate.

IT is available in both the technologies, so this is also not an issue of quality but the choice to make according to the use. So in these three OLED have an amazing response time so OLED is the winner in this.

Future Aspect of QLED vs OLED TVs

The best picture quality, for now, is the OLED by LG company. But on the other hand, Samsung is also working on to be ahead of LG’s OLED technology. As it is working on a new technology emissive display technology called MicroLED.

MicroLED would be using millions of pixels tiny LEDs and will produce the best black and also working to maintain the best contrast ratio. So let’s see what will happen in between both of them in the future. But for now, OLED by LG is the better option.

Conclusion

In the future, there will be new technologies and more advanced versions of these as well. For now, if you do not have the issue of budget and there is no direct sunlight on TV throughout the whole day. OLED is the best option for you.

If you are worried about the screen burn-in and love to watch the brighter colors irrespective of the contrast ratio, you must go with QLED TVs.
