Summary
What exactly are QD-OLED televisions? The technology behind television is undergoing rapid change. In the last few years, the finest OLED televisions were the indisputable top dogs of the best televisions that you could purchase. However, in the present day, the world of television is buzzing with a new sort of OLED technology known as QD-OLED, which stands for quantum dot OLED.
What exactly are QD-OLED televisions?
In essence, QD-OLED is a mixture of the finest TV technologies that we have seen up to this point, and it is finally making its way into some of the most cutting-edge and cutting-edge new televisions. For instance, the new Sony Bravia A95L is one of the televisions that is using this technology.
To be more specific, what precisely is a QD-OLED screen, and how does it differ from a conventional OLED panel? What you need to know is explained here.
Pros and disadvantages of OLED televisions
Because of OLED technology, display panel technology in general underwent a full transformation. The term “organic light-emitting diode” (OLED) refers to a device that is constructed using an organic compound that emits light when electricity is applied to it. The more electricity that is applied to the OLED, the brighter the light that it emits.
Because of this technology, it is now possible to exercise individual control over each and every pixel that makes up an OLED screen. This has a significant bearing on the dark levels of individual pixels. This is due to the fact that anytime there is black in a picture, pixels are simply turned off, which results in a real, deep black that you would not get on a television that has big backlights.
Even though there are OLED panels that make use of various organic compounds in order to generate a variety of colors, the majority of today’s OLED panels really just employ OLED technology as the backlight of the television. They then pass the white light that is produced by the OLED technology through a color filter in order to generate a variety of colors. They are referred to as WOLED, which stands for white organic light-emitting diode.
This, however, is not without its restrictions. When I said that the amount of power that is applied to an OLED pixel determines how bright it becomes, do you remember? Although this is theoretically correct, increasing the amount of power that is applied to an OLED pixel would also reduce its lifetime.
In addition to this, the color filters that have historically been used in OLED screens further reduce the amount of brightness that is present. This is due to the fact that they effectively only block light that is not wanted, allowing light to only travel through the colors that are sought in order to produce the color that is necessary for the picture.
Because of the necessity to regulate the lifetime of a panel and the fact that a color filter causes some brightness to be lost, organic light-emitting diode (OLED) panels are often not as bright as their non-OLED counterparts.
For QD-OLED, what is the difference?
The principle is somewhat altered by QD-OLED televisions. QD-OLED televisions continue to exclusively employ OLED technology as a backlight; however, rather than creating a bright white light as a backlight, they create a brilliant blue light, and then they pass that light via a layer of quantum dots. In situations where the picture requires a blue background, the backlight is permitted to pass through without any changes. The light is directed via a quantum dot subpixel that is either red or green, depending on whether it is intended to be red or green.
Due to the fact that quantum dots are extremely efficient in comparison to conventional color filters, very little brightness is lost while a pixel is producing red or green light. Furthermore, quantum dots are still capable of producing white light by mixing all of the subpixels together.
Aside from the illumination, what precisely are the distinctions between the two things?
Color quality: Quantum dot technology is well-known for its ability to produce a broad spectrum of brilliant colors. As a consequence, QD-OLED panels are able to show a wider variety of colors than WOLED panels.
Our study of the LG G3 OLED TV, which was one of the best OLED TVs of the previous year, revealed that it covered 72.49 percent of the Rec. 2020 color spectrum. On the other hand, the Sony A95K, which was one of the finest QD-OLED TVs, covered an even broader 89.44 percent of the Rec. 2020 color range. This is a significant difference, and it indicates that QD-OLED panels ought to generate pictures that are far more lifelike in general.
The size of the television may be one of the few areas in which OLED televisions continue to be superior. Despite the fact that there are televisions with both technologies that are 55 inches, 65 inches, 75 inches, and more, QD-OLED televisions that are smaller than 55 inches are not now available.
It is quite probable that this will change as the technology gets more widespread, and to tell you the truth, 55- and 65-inch televisions are the most frequent in any case. However, if you are looking for something smaller, such as a television with a 42-inch screen, your options are now restricted to something like the LG C2 OLED.
Due to the fact that QD-OLED televisions are very new, their price tag is rather high. Since the introduction of organic light-emitting diode (OLED) panels more than a decade ago, the cost of this technology has significantly decreased. As you may anticipate in light of this knowledge, OLED televisions are more affordable than QD-OLED televisions. On the other hand, it could shift over time.
In reality, QD-OLED televisions have fewer materials than OLED televisions do since they have fewer layers and do not have the color filter or the polarizer that is linked with them. In order to determine whether or not QD-OLED televisions will wind up being more affordable than OLED televisions, we will have to wait and watch. However, QD-OLED panels seem to be becoming more affordable, and this trend is expected to continue as the cost of making them decreases and the ingredients that are required become more readily available.
The question now is, which one should you purchase?
The fact that QD-OLED televisions are superior to OLED televisions in almost every respect cannot be refuted. They are more vibrant, generate a greater variety of colors, and maintain the same degree of profound blackness.
There is now just one significant drawback to QD-OLED, and that is the fact that the technology is quite new, and as a result, it is not very generally accessible. Additionally, the cost of these devices is quite high. Although this should change in the future, if you are searching for a television that is considered to be among the finest, you will most likely end up with a QD-OLED television like the Samsung S95C.
