Quantum Dot technology arrives to revolutionize televisions
With the last CES held at the beginning of the year, we could see how innovation in televisions has been present. It speaks specifically of the Quantum Dot technology, which presents great differences with what we have been appreciating with the OLED.
We have seen from 3D televisions to models that adapt their position according to the person's posture, but all eyes are on the QD-OLED.
In a few words, it is the technology that is responsible for giving more vivid tones to the displayed images, but in this article we will discover more.
What is Quantum Dot technology? Also known as QD-OLED
This new technology has come to stay and be the main element of the televisions of the future; although they are already part of the present.
Its function is to give a much more realistic image of what is seen on the screen so that the viewer has a better experience.
How do you do it? Through small lenses of tiny size that are made from semiconductor elements. These crystals are responsible for lighting up with a certain color once the light is reflected on them.
The result is more than extraordinary, giving a much more vivid image, full of colors, with an accentuated brightness that gives it a much more natural sensation.
Is this technology new?
It should be noted that quantum dot technology has been present in televisions for some time now.
The difference is that they have now decided to implement the elements corresponding to OLED technology, this being of higher quality than LCD-LED.
This is how, with the combination of both QD and OLED technology, you get the best of both worlds. With respect to the latter, the image is capable of highlighting black colors, also providing greater sharpness in contrasts.
All of this, combined with the color enhancement and higher brightness of QD, results in a unique visual experience for the viewer.
How does QD-OLED technology work?
In the first instance it was developed by the technology giant, Samsung, but it is also available in terminals from other companies.
Basically, the quality of your image is based on the size of the crystals, which vary between 2 and 10 nanometers. Why does its length matter? It is because of the waves that are responsible for transmitting the particles that the displayed colors are affected once the light reflects them.
Specifically, the quantum dots are separated by an OLED panel, which is responsible for transmitting blue lights. Thus, the pixels are colored either red or green when necessary.
For each pixel, we have three sub-pixels in charge of transforming into either red, blue or green when light is reflected.
Know the advantages of Quantum Dots technology
As a new and innovative technology, combining two elements for image display, you get the best of both worlds. In essence, we have the advantages of both QD and OLED for better visual quality.
Efficiency or nothing
One of the main advantages they present is that quantum dots work with a greater optimization in terms of energy use. Thus, they tend to be better efficiently speaking than other technologies.
Also, this efficiency gives them the ability to achieve higher quality gloss standards without losing stability in the process. It means that, it is a feature that counteracts what was seen in OLED technology that had these types of problems.
The quantum dots are joined in such a way that they do not allow light to escape between them, and combined with OLED technology they offer greater sharpness.
This advantage means that the images displayed on the screen do not present any type of halo of light in their silhouette, being fully contrasted.
Better viewing experience
When using QD-OLED technology and participating in its quality, we realize the great visual experience they provide. It is due to the multiple functions it has, where one of the main ones is the ability to maintain the hue of colors in bright areas.
On the other hand, they guarantee that in the dark parts any element can be visualized without problem, emphasizing the definition.
Not everything is perfect; these are the disadvantages of the QD-OLED
It should be noted that this is an evolving technology, so advances that allow better quality are still expected to be announced. However, what has been seen so far gives a lot to talk about, especially with regard to the viewer's visual experience.
Undoubtedly, one of the main disadvantages of this new technology is that it is just that, recent, and therefore, it can be expensive. Innovation can be expensive, but you get a product of the highest possible quality, shaped by the latest advances in visual technology.
For now, and pending further advances in their technology, QD-OLED glasses are not available in a much smaller size than they are. It means that its use is only enabled for televisions.
In other words, we still have to wait to witness its adaptation to much smaller terminals such as smartphones or tablets. Of course, if they are able to reduce the size of the panels without losing attributes of their enormous quality in image reproduction.
