The TV market is constantly changing and evolving, with new technologies and advancements being made all the time. When you are complacent about knowing everything about TVs, a new type of TV pops up and changes the game.
One such recent development in the world of TVs is QLED technology. However, even with the growing popularity of QLED TVs, there are still some misunderstandings about this technology. So, the question is, what is QLED TV, and are the myths about them all true?
QLED stands for "Quantum Dot Light-emitting Diode." It is a type of LED/LCD that uses quantum dots to create its display. These quantum dots are nano-sized molecules that emit a distinct colored light of their own when exposed to a light source.
When it comes to QLED televisions, the dots are encased within a film, and an LED backlight supplies the light that strikes them. The light then goes through a few different layers within the TV, including a liquid crystal (LCD) layer, to generate the image on the screen.
These dots produce varying hues of light, depending on the particle size. The larger the particle size, the more red color is produced; the smaller the particle size, the greater the blue produced.
Since particle sizes adjust at quantum-level speeds, they are able to emit accurate colored light with high efficiency and repeatability. This high luminance efficiency makes QLED TVs capable of producing some of the most accurate and vivid colors that you will find on any television.
As awesome as QLED TVs are, there are still some misunderstandings about them that give people a wrong impression of what they are. So, in the following section, we will dispel some of the most common misunderstandings about QLED TVs.
The first rumor is that QLED TVs are OLED TVs. While there are similarities between the two technologies, they are actually quite different. The main difference between them is that OLED TVs do not rely on conventional LED (light-emitting diode) technology to generate images on the screen. Instead, they make use of organic LEDs for displays.
There is no need for an OLED screen to have a backlight because each pixel of it emits its own light. This provides a significant benefit in terms of contrast and color sharpness because the panels can contain completely dark pixels next to extremely bright pixels. It is possible to observe the image from 180 degrees due to the uniformity of light, color, and contrast produced by the individually lit pixels.
In comparison to other types of televisions, including QLED, OLED panels are significantly thinner due to the lack of a backlight in them. Depending on the model, this may make it bendable or allow for poster-style attachment to the wall. The one disadvantage of OLED is that it has not garnered widespread public acceptance, which has resulted in the decrease of manufacturers who offer them and fewer size options available for the consumers.
Due to marketing strategies, some TV manufacturers claim that QLED TVs are self-illuminating. This is completely not the case and can cause consumers to make a wrong judgment of the product they are looking to purchase.
As mentioned earlier, QLED TVs rely on an LED backlight to produce images on the screen. The light which is emitted by the quantum dots then creates the desired colors and hues. In more detailed terms, a Quantum Dot Enhancement Film (QDEF) sheet is placed on top of the backlight unit in a QLED display module. Rather than generating light on its own, the QDEF uses the backlight unit to control the intensity of the light it receives to achieve more desirable results, such as increased color saturation.
However, manufacturers are now working on a technology that will get rid of the need for a backlight. This QLED of the future is still in development. But once it is released, it will be a more efficient way to produce images on screens and should result in even better picture quality.
QLED televisions are available in resolutions ranging from 4K and above. While it is feasible to build QLED panels with a lesser resolution, most producers are focused on developing products of top-tier quality rather than simply introducing any random new tech.
As a result, any QLED display you see on the market will almost certainly be Ultra High Definition (UHD). But on the other hand, UHD TVs are not all QLED — they can come with different panel technologies like LED, LCD, OLED, QLED, and even a projector.
This is another common misunderstanding about QLED TVs. Some people believe that quantum dots emit blue light, so they are harmful to the eyes and can cause long-term damage.
While it is true that blue light can be harmful when your eyes are exposed for long periods, QLED TVs rely on dimming technology and their shutters to achieve the necessary levels of light and color needed to create images on the screen. This means that only a minimal amount of blue light that is produced is actually emitted from the TV screen.
In addition, it's important that when making a purchase, you go for the very best QLED TV you can afford. Poor quality QLED TVs may not meet the same standards as those produced by the top brands. So, if you're worried about potential negative effects on your eyesight, it's best to do some research and find a reputable manufacturer with a history of creating high-quality products.
When coming home after accumulating the tiredness of the whole day, nothing feels better than relaxing on the couch with your favorite show. While relaxing in front of your TV, you are sure to have the desire to enjoy the best viewing experience. That's why a TCL TV is a great choice for your home entertainment system.
The TCL QLED TV C725 doesn’t just deliver stunning images and incredible detail, but it also offers safe, long-term viewing for your peace of mind. With a built-in micro-dimming technology, TCL QLED TVs automatically analyze pictures and adjust brightness for the best content.
TCL TVs are well-known for their wide range of features, including their ultra-high dynamic contrast ratio (UHDCCR) for deeper blacks and brighter whites and their support for many HDR formats (HLG, HDR10) and 4K/UHD cinema-grade resolutions. This guarantees that your watching experience is as authentic as possible.
In addition to HDR10, TCL TVs also offer Dolby Vision, which provides a more immersive experience with even more accurate colors and contrast. With Dolby Atmos, you'll be able to experience immersive audio that will place you right in the thick of things.
It is worth doing thorough research about QLED TV before you buy a new one. And with all of the misinformation out there about QLED TVs, it can be hard to know what's true and what's not.
This piece can be a starting point for your own investigations. But in general, it's important to remember that QLED TVs are high-quality products with amazing features and stunning visuals. If you’re trying to get the best home entertainment experience, a TLC QLED TV should definitely be at the top of your list.
