LED and regular LED televisions are among the most common television technologies. Although they are very similar in many ways, their main differences mean that their overall performance tends to be very different. In general, QLED televisions are generally more expensive but also more shiny and with better and more vibrant colors. LED televisions tend to be very inexpensive, which makes them ideal for those who have a budget or for a television in a less used room.
It should be mentioned in advance that LED and traditional LED televisions are versions of the LCD screen. They both use LCD panels to create an image, but use different LED versions to create light so that you can see the image on this panel. Neither of the two uses LEDs to create an image directly like OLED or Microled. The mini-LED of more recent technology is like an evolution of Qled and LED.
What is the difference between Qled and LED?
Qled and LED use electroluminescent diodes to produce the light that passes through an LCD layer to create an image. The “LED televisions” are more precisely called LCD LED. “Qled” is a marketing term that refers to a specific LCD LED screen subset. In other words, all Qled are LED televisions, but all LED televisions are not QLED.
The main difference is the addition of quantum points, which I will explain more in the next section. Because Qleds tend to be more expensive than ordinary LEDs, they also tend to have more LEDs. TVs that are simply called “LED” are often the cheapest offers on the market, and as such, generally have a handful of LEDs placed on one side of the screen (often below).
Quantum points: the ‘Q’ in Qled, Qned and more
Blue LEDs, which are used in most backlight conceptions, excite red and blue quantum dots (the intermediate layer in this diagram). This, now RVB Light, is then manipulated by an LCD layer to create the image you see.
Quantum points are tiny particles with an incredible ability to change a color of light into another light color. They can do it with almost perfect efficiency. The color they create can be set to the exact color that a manufacturer wishes, so that the TV can create the color range necessary for HDR content.
Thus, in general, televisions that use quantum points tend to be brighter, with more realistic colors, than televisions that do not. Due to these larger performance, they often have, but not always, more LED than ordinary LED televisions, which allows things like local gradation, which offers better image quality. These are fairly wide generalizations, however, it is therefore preferable to judge the specific features and performance of each television beyond what business marketing calls it.
There is a similar television technology which is in a way an evolution of LEDs and Qled called mini-LED. These have a lot more LEDs and offer performance similar to the OLED.

I have already covered quantum points, even going to a factory where they are made. They are a remarkable technology which is experiencing wide use in the world of television. Not only do they help LCD LED televisions to create brighter colors, but they are also used in certain OLED TVs to do the same. Several companies are also working on quantum -vis -à -vis direct screens, not at all LCD or OLED technology. It’s a bit in the future, however.
Is it a real “qled”
Various colors of quantum points.
While Qled and other names related to Q have become marketing success, companies began to use these terms for televisions that may not have “Q” at all. Since the name was created by a marketing service, it has no legal or scientific meaning. He implied Quantum points because this is what the first “Q” models had, but nothing requires a television called “Q” to have Quantum points. As such, some companies could merge what is really in their televisions.
There are other technologies, including phosphores, which can improve the performance of “regular” LED televisions without specifically using quantum points. Is it always fair to qualify these televisions as “Q” something if they have no quantum points? I would say no, but I also hated the term “LED TV” because they are actually LCD televisions with a spoonful of marketing over it. I think it is fair to argue that it is misleading, but if the performance is similar, is it important?
In other words, it is better to check the opinions on how the TV actually works instead of relying on the marketing terms of a business. To this end, see our choices for the best television.
