do you know that What is QLED, If you have just now gone to the shop or showroom to buy TV, then QLED TV must have come in front of your eyes.
But just by looking at it, it is difficult to tell what differences have been brought in QLED technologies as compared to OLED. Because these technologies are often not much different in appearance.
Where QLED TV There is a proprietary panel technology developed by Samsung for its top-tier televisions. By using a metallic quantum dot filter, QLED panels enhance color and contrast, increasing its ability to produce HDR and 4K images compared to other non-quantum dot LCD-LEDs.
These OLED and QLED are almost similar in appearance but there is a lot of difference in their technologies. That’s why today I thought why not provide complete information about what is QLED TV to you people so that you can also understand it better and you can also choose the right TV for yourself.
Then without delay let’s start and know that this What is QLED In Hindi and how it differs from OLED.
What is QLED
The full form of QLED is Quantum Dot LED. Its name is because quantum dot technology has been used in this TV in an LED panel.
Quantum dot + LED = QLED,
By the way, this is not a new technology, but it is the fourth-generation quantum dot, which was first introduced in 2015 in Samsung’s TVs.
It has been launched to compete with Mehjuda OLED Tv. In this, Samsung says that superior technology has been used in QLED and it has more advanatges than OLED.
What are the features of QLED?
Now let’s know more about the features of QLED.
1. The full form of QLED is Quantum Dots Light Emitting Diode,
2. QLEDs are made of Quantum dots which are tiny semiconductor crystals ranging in size from 2 nm to 10 nm.
3. Quantum dots emit color light depending on the energy gap of the materials used in them and their size. The greater their dimension, the greater will be the wavelength of the emitted light.
4. Different semiconductor combinations are used in the manufacturing of quantum dots in which CdSe, CdS, PbSe, PbS, InAs, InP etc. are important.
5. QLEDs do not produce light on their own. Rather QLEDs use the backlight unit for illumination. This light, which is emitted from the backlight, is passed through a series of plates, which finally creates an image.
6. The six layers that are used to create a color image are Backlight panel, reflector, polarizing filter, TFT array, color filter glass, quantum dots color filter and polarizing filter.
What is QLED TV?
QLED TV uses such technology in which quantum dots pure color They also generate LED light by transferring it through quantum dot color filters.
What is QLED Technology?
QLED Technology provides quantum dots on top of a layer backlight which emit pure primary colors. This delivers improved brightness and produces deeper colors, while also limiting the loss of light.
It provides sharper viewing angles, that too by absorbing extra surroundings light.
QLED produces a higher peak brightness that too 800-2000nits (There is a unit for visible light intensity).
Its advantage is that it provides superior color accuracy, as well as significantly increases the brightness levels, which produces sharper and more vivid colors.
What are the different models of Samsung QLED TV?
Now let’s know about the different models of Samsung’s 2018 QLED TV – Q9F (65-inch, 75-inch, 88-inch), Q8F (55-inch, 65-inch, 75-inch), Q7C (55-inch, 65-inch), Q7F (55-inch, 65-inch , 75-inch) and Q6F (49-inch, 55-inch, 65-inch, 75-inch, 82-inch).
Along with this, a lot of improvements have been made in the color and contrast in these models. Now the 2018 models have also included Bixby voice assistant and HDR10+ compatibility.
How do QLEDs work?
Now let us know what is the technology behind QLED. If asked about the work of Quantum dot TV, then quantum dots of a layer or film are placed in front of a regular LED backlight panel.
This layer is made up of tiny particles that emit their own individual color depending on their size (which ranges from about 2 to 10 nanometers). Basically, the size of these particles dictates the wavelength of the light they emit, hence the many different colours.
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, in which the particles have been changed, because now there is a new metal alloy core and new metal alloy shell has been used.
This enhancement not only enables better color accuracy but also enables color accuracy at its higher peak brightnesses.
This is the reason why the importance of QLED increases. Their ability to produce colors that have higher brightness and provide better color volume than before.
It is because of this feature that QLED proves itself better than OLED with its ability. It is also able to preserve the colors in their peak brightness which is not possible in the case of OLED. At the same time, this peak brightness is much higher than that of OLED.
Due to this, QLED provides more visible color, which is better in vibrant delivery of HDR content as well as providing a great visual experience to the viewer.
What is the difference between QLED and OLED?
Difference between OLED and QLED in Hindi: Let us now know about the different features of these two display technologies such as contrast, viewing angle, brightness, and other performance, as well as how they differ from each other. .
black level
The black level of OLED allows for more contrast and richer colors. So in this case OLED is very superior to QLED.
Whereas in QLED TVs, efforts have been made to improve the LED display black level performance, but still they have to depend on the backlights shining which is behind an LCD panel. It suffers from “light bleed” even though it has advanced dimming technology.
This causes a slight haze or “halo” around bright objects and blurs lines that should be sharp.
BRIGHTNESS
When it comes to brightness then QLED is ahead in it. This is because it contains more quantum dots which helps it to burn more brightly. Their color volume is large.
Whereas the brightness level in OLED is not that high.
COLOR SPACE
There was a time when OLED was at the forefront but quantum dots, by improving their purity of backlight, allow QLED TVs to achieve better color accuracy, color brightness, and color volume.
Wherein now companies are implementing expanded color volume in their new QLED models, so that it can improve their saturation in higher brightness levels.
If seen, both QLED and OLED have good color space.
RESPONSE TIME
Response time means the time each diode takes to turn from ON to OFF. Wherein there is motion blur less than faster response time.
OLED, in which because of their smaller diodes working in single pixels, they are simply very fast in terms of response time. Wherein the diodes of QLED are not only slower but they are also behind the LCD panel and they illuminate a cluster of pixels and not a single pixel. That’s why their response time is slower.
That’s why OLED is much better in response time than QLED.
INPUT LAG
When it comes to input lag, both OLED and QLED are on the same level. Where QLED already has better input lag, the input lag of OLED has now been improved. So OLED is still a better option for gamers.
VIEWING ANGLES
In this, OLED is far ahead compared 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 side to side, or up and down.
But nothing like this happens in OLED and its best viewing angle is in all directions. In this you can see upto 84 degrees without any luminance degradation.
That’s why OLED is better than QLED in terms of viewing angles.
size
When it comes to the size of the TV, then QLED is ahead of OLED in many ways in this matter. While the maximum size of OLED is up to 55 inches, it is more than 100 inches in QLED.
LIFESPAN
QLED is also much ahead in terms of Lifespan as compared to OLED. Where the brightness of OLED starts decreasing gradually over time, nothing like this happens in the case of QLED.
POWER CONSUMPTION
OLED panels are very thin, so they do not require any backlight. In addition, OLED TV’s are also lighter in weight than QLED TVs. That’s why they require very little power, which makes it more efficient. In this regard, OLEDs are ahead compared to QLEDs.
price
There was a time when QLED TVs could easily win this section because of their low prices, but now there has been a lot of change in the prices of OLEDs, so it would not be correct to say that QLEDs are cheaper than OLEDs. In.
OVERALL
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 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. It offers OLED best viewing angle, best black levels, better contrast, and with this it uses less energy due to being lighter, thinner, which makes it efficient,
Now you have to decide which TV is right for you. By the way, the matter of both the technologies is different. Keeping everything else in mind, you have to choose one for yourself.
