What is QLED and How does it QLED work?
Now let’s know what is the technology behind QLED. If Quantum dot TV is asked about work, then a layer or quantum dots of film is placed in front of a regular LED backlight panel.
This layer is made up of tiny particles which emit their own individual color depending on their size (which is between 2 to 10 nanometers). Basically, the size of these particles dictates how much the wavelength of light will emit, so there are so many different colors.
According to Samsung, their quantum dots emit more than one billion colors.
If we talk about the third-generation of Quantum Dot Tvs, then they are called QLED, they have been replaced with particles, because it has now used a new metal alloy core and a new metal alloy shell.
This enhancement has not only enabled better color accuracy but it also enables color accuracy to its higher peak brightnesses.
This is the reason that the importance of QLED increases. Create these colors of their ability which have higher brightness and it provides better color volume than before.
Due to this feature, QLED asserts itself better than OLED because of its ability. It is also able to preserve colors at their peak brightness, which is not possible in the case of OLED. At the same time, this peak brightness is much higher than OLED.
Due to this, QLED provides more visible color, which is better in making vibrant delivery of HDR content and also in providing a good visual experience to the viewer.
What is the difference between QLED and OLED?
Difference between OLED QLED: Let us now know about the different features of these two display technologies such as contrast, viewing angle, brightness, and other performance, along with how they are different from each other. .
The black level of OLED allows more contrast and richer colors. So in this case OLED is much better than QLED.
While LED display in QLED TVs has been tried to improve the black level performance, but still they have to depend on the backlights shining which is behind an LCD panel. Despite having advanced dimming technology in it, it is also suffering from “light bleed”.
This causes a slight haze or “halo” in it and blur the lines around the bright objects which should be sharp.
QLED is ahead when it comes to brightness. This is because it has more quantum dots, which helps it burn more brightly. Their color volume is large.
The brightness level in OLED is not that much.
There was a time when OLED was at the forefront but quantum dots, by improving their purity of backlight, they allow QLED TVs to achieve better color accuracy, color brightness, and color volume.
At the same time, companies are implementing expanded color volume their new QLED models, so that it improves their saturation to higher brightness levels.
If seen, both QLED and OLED have good color space.
Response time means the time that each diode takes from ON to OFF. There is less motion blur than faster response time.
OLED, with their smaller diodes working in single pixels, are simply very fast in terms of response time. The diodes of QLED are not only slower but also behind the LCD panel and illuminate the cluster of pixels and not the single pixel. Hence their response time is slower.
So OLED is much better in response time than QLED.
When it comes to input lag, both OLED and QLED are in the same position. While QLED already has better input lag, the input lag of OLED has now been improved. Therefore OLED is still a better option for gamers.
OLED is far ahead in comparison to QLED. Where QLED has its best viewing angle dead center, and its picture quality gradually diminishes in both color and contrast as you move from side to side, or up and down.
But nothing like this happens in OLED and its best viewing angle is in all directions. In it, you can see upto 84 degrees without any lumiance degradation.
So OLED is much better in terms of viewing angles than QLED.
When it comes to the size of TV, then QLED is ahead in many respects from OLED. Where the maximum size of OLED is up to 55 inches, in QLED it is more than 100 inches.
In terms of lifespan also, QLED is far ahead compared to OLED. Where the brightness of OLED gradually decreases with time, there is nothing like this in case of QLED.
OLED panels are very thin so they do not require any backlight. Also, OLED TVs’s lighter in weight as compared to QLED TVs. Therefore, they require very little power, which makes it more efficient. In this case OLED are ahead compared to QLED.
There was a time when QLED TVs could easily win this section because of their low prices, but now OLED prices have seen a lot of change, so it would not be right to say that QLED is much cheaper than OLED In.
Now it is a matter of who is the winner in the end!
QLED is ahead in many sections such as brightness capability, accessibility, size, and lifespan, while some upgrades have also improved its black levels and off-angle viewing.
At the same time, the brightness of a QLED TV is also much better than OLED if we talk about daylight hours.
Now when it comes to picture quality, then there is no one better than OLED. This OLED offers best viewing angle, best black levels, better contrast, and with it being lighter, thinner, it also uses less energy which makes it efficient.
Now you have to decide which TV is right for you. By the way, the talk of both technologies is different. Keeping all the other things in mind, you have to choose one for yourself.
What are the Advantages of QLED?
Now let us know about the advantages of QLED.
➨ Quantum dots which are used in the construction of QLED can resist moisture much better and hence QLED based products have a longer life.
Due to its high resistance to moisture, there is no need for expensive vacuum evaporation process. Therefore its price is low.
➨ They are available in higher display sizes and hence they provide more options to consumers.
➨ It is thin and is also of very low weight.
Switching Its switching speed (between ON / OFF) is very fast.
➨ Its brightness is brighter by about 50 to 100 times if we compare it with CRT and LCD display types.
➨ It has lower power consumption.
➨ QLED based TVs are mostly not susceptible to burn-in like OLED TVs do.
➨ It costs less than the rest.
What are the Disadvantages of QLED?
Now let us know about the disadvantages of QLED.
➨ QLEDs do not produce light on their own. Rather QLEDs use backlight unit for illumination.
➨ QLED based TVs suffer from the “light bleed” effect. These effects are visible in some screens. In this, a slight haze appears around the bright objects, where only the blurs lines should be seen, that too usually sharp.
➨ QLED based display screens, has best viewing angle in dead center. At the same time the quality of the picture starts to decrease gradually (both color and contrast) when we move from side to side or up and down.
➨ It contains less saturated blue.
