What is QLED Display and how is it different from OLED?

Do you know what this QLED is? If you have currently gone to the shop or showroom to buy TV, then QLED TV must have come in front of you.

But just looking at it, it is difficult to tell what differences have been brought in QLED technologies compared to OLED. Because these technologies are often not very different in appearance.

Where QLED TV is a proprietary panel technology developed by Samsung for its top-tier televisions. By using a metallic quantum dot filter in it, QLED panels enhance color and contrast, increasing its HDR and 4K images capability as compared to other non-quantum dot LCD-LEDs.

They are often similar in appearance to OLED and QLED but there are many differences in their technologies. So today I thought why should you be provided complete information about what QLED TV is, so that you people can also understand it better. Wherever you too can choose the right TV for yourself.

Then without delay, let's start and know what this QLED is in Hindi and how it differs from OLED.

The full form of QLED is Quantum Dot LED. Its name is because quantum dot technology is used in this TV in an LED panel.
Quantum dot + LED = QLED.

By the way, this is not a new technology, rather it is the fourth-generation quantum dot which was first introduced in Samsung’s TVs in 2015.

It has been launched to compete with Mezhuda 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. QLED has full form Quantum dots Light Emitting Diode.

2. QLEDs are made of quantum dots which are tiny semiconductor crystals whose sizes range from 2 nm to 10 nm.

3. Quantum dots emit color light based on the energy gap of the materials used in them and their size. The larger their dimension is, 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 prominent.

5. QLEDs do not produce light on their own. Rather QLEDs use backlight units for illumination. This light, which is emitted, is passed through series of plates from the backlight, which eventually 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 a drone camera and how to make?

You may have heard this technological term "drone camera" in recent times. But do you know what is this drone in the right way? How does this work? If you do not know the answers to all these questions, then there is no reason to panic because today we are going to discuss about this state-of-the-art gadget. It sounds as strange as it sounds, but it is also visible. In the right sense, it is a robot that can be controlled by humans. But it is a flying robot. It is humans who have prepared themselves for editing their works. Although these drones can do many tasks, but they are designed mainly for the work that humans are at risk of being killed by themselves. By the way, we are going to know about all its functions further. Therefore, read the article completely without skipping anything. With this, you can get to know about this latest technological machine in detail. Then you do not wait any more, let's start and know about what a drone is and how it works. What does a

What is 6G and how will it be better than 5G?

Perhaps you have not yet heard what 6G is? You will also hear how 5G has not arrived yet. Which will come soon in our country. At the same time, it is also being used in many different countries. But even with the absence of 5G, there is a lot of sway over 6G. Some research groups have also started doing their research on it. And they believe that within the next 10 years i.e. within 2030, 6G will also be in front of us. "6G" is also a wireless technology which is going to be developed to a great extent with "5G". Meaning that those who are unable to do the work of 5G will easily do 6G. By the way, much information about 6G is not available on the internet but still after doing a lot of research, I have collected some important information for you. So if you are interested on Future Tech, then this article today has shared something with you about what is 6G and how it will be better than 5G. Hope you like my efforts. Then without delay, let's start and know 6G
