NanoCell vs QLED: Compare the Technologies in Smart TVs | TV week

NanoCell and QLED are two technologies that promise to improve the picture quality of Smart TV. NanoCell is only found in LG TVs, while QLED was invented by Sony, but has been commercially adopted by Samsung, which also makes panels of the type for other brands. Generally, Both technologies are very similar from a technical point of view, which makes the choice between them very detailed. Both, however, Cheaper Alternatives to OLED TVsa more modern type of television, can reproduce colors more faithfully by using a combination of light-emitting diodes rather than a backlight.

Check out the differences and similarities between the NanoCell and QLED technologies below. See how they can improve the picture of a 4K TV.

1. What is the difference between NanoCell and QLED?

As mentioned earlier, LG’s NanoCell and Samsung’s QLED have many things in common: Both use traditional LCD panels with LED backlightIts main purpose is to display more realistic colors. What distinguishes the two types of TV is the technology used in each.

Before explaining, it is necessary to return to some concepts about the work of televisions. In common LCD screens, images are formed when light from the backlight passes through the color filter of the LCD screen. In this filter the primary colors: blue, red and green. Together they make up the color images we see on TV. However, light can create various distortions in the colors of the painting, making it dull and lifeless.

In the case of NanoCell displays, the panels contain an additional layer of 1 nanometer (0.00001 mm) nanoparticles that filter out colors of the wrong wavelength, leaving only purer colors. The result is sharper images with less blur.

QLED technology uses a quantum dot filter with more than one million nanocrystals. Nanocrystals come in different sizes and each produces a different color. For example, 1 nm emits blue, while 3 nm emits red. As the light passes through the nanocrystals, they adjust the color that appears on the LCD panel, forming an image with minimal distortion.

2. Advantages and disadvantages of NanoCell and QLED

Both NanoCell and QLED can reproduce more accurate colors – and they work very well. Advantages and disadvantages depend on other factors, such as the type of board each company uses.

LG, for example, uses IPS panels, which have a better response time and a much wider viewing angle. But that also means lower contrast and grayer blacks, even with NanoCell technology. This can be circumvented with Full Array Dimming technology (which illuminates certain areas of the screen), but it is only present on some models.

On the other hand, Samsung uses VA panels with QLED, which have a wider contrast and can display darker tones more clearly, but with a narrower viewing angle.

Thus, choosing between one technique and another must take these and other factors into consideration. If it is a brighter environment or if the use is for gaming, NanoCell comes out on top. If the environment is darker, the QLED feature becomes more noticeable.

Unlike OLED, which allows for thinner TVs, TVs with NanoCell technology and QLED maintain Standard appearance for most flat panel displays. This does not mean that manufacturers do not like innovation. For example, the Samsung 4K Smart TV called The Frame uses QLED technology and stands out as one of the most highly praised TVs in the market. This model comes with a detachable frame that can be interchanged as a picture.

LG Nano TVs, on the other hand, feature ultra-thin bezels with a metallic finish and the option of stand-style support. Furthermore, the LCD has the advantage of being very large without costing a fortune, as is the case with OLED screens.

Since they both use LED backlighting, the power consumption is similar. For example, the average consumption of a 55-inch LG NanoCell85 is 165 watts per hour. On the other hand, the average consumption of Samsung QLED Q60B of the same size is 150 watts per hour.

they are Very economical compared to OLED. For example, the 55-inch LG OLED A1 consumes an average of 347 watts per hour, twice as much as the versions with LED backlights.

The great advantage of NanoCell and QLED is that it Significantly improve the picture quality of an LCD TV at a much lower cost than an OLED TV. In addition, they are less prone to problems such as burn-in (image retention on the screen) and consume less power, as is the case with OLED technology.

Among the models equipped with NanoCell, the 50-inch LG NANO75 Smart TV is one of the best value-for-money models, which can be found for R$3,108 on Amazon. Among the models equipped with QLED, the 55-inch TCL C715 stands out, which costs R$ 3148.
