With the advancement of progress more and more technologies are becoming part of the world of Smart TVs. The deepest and most significant innovations are occurring above all with regard to panel technologies. 

If until a few years ago the LED was seen as the non plus ultra, today new and more efficient vision systems have been developed, in this article we will analyze the main differences between Nanocell vs OLED vs QLED; the three main technologies developed by multinational television manufacturers. 

We will understand what are the preponderant aspects and strengths of each system, analyzing the strengths and weaknesses. Let’s start!

Nanocell: what it is, what it means and how it works

Nanocell vs OLED vs QLED

Let’s start by saying that Nanocell technology was invented by LG technicians ; the only ones, until now, to implement this type of improvement on televisions. Unlike what one might think, Nanocell TVs are actually LED TVs. In fact, the backlighting system they use to let the light arrive is formed precisely by LED lamps; the difference compared to a “normal” TV that uses this type of technology is in the next phase. In fact, a TV is made up of several “elements”, the backlight is the first, then there are the RGB filters and finally the LCD panel. 

The Nanocell differs from a normal LED TV in the second phase, that is the one linked to the Green, Red, and Blue filters. In fact it is here that the nanoparticles (infinitesimal size of 1 nanometer) have the task of filtering the wavelengths better (eliminating those in excess), in order to make the colors of a higher sharpness than ordinary LED TV. It follows that the images on a Nanocell TV have colors that are much more faithful to reality, thanks to the exclusion of all those wavelengths that have been captured by the tiny nanoparticles.

How to clean a Nanocell TV?

A question that we are often asked by those who have bought a Nanocell TV or are about to make the purchase is the following: how do I clean the screen? Don’t worry, TVs that use Nanoparticles are made up (like LED TVs) of 3 different “layers”: the backlight system, the RGB filter and the LCD (liquid crystal) panel. 

So the actual panel is a very normal LCD screen, and as such it must be cleaned with the same precautions that must be used for all liquid crystal TVs . What we recommend at is to use a dry cloth (possibly microfibre) and specific products for PC or TV screens, there are many in large electronic store chains or even on sites such as Amazon.

Nanocell Pros:

  • Very Bright Display and Vivid Colors
  • Mid-Range Budget
  • Less Reflective (Matte Appearance)

NanoCell Cons:

  • NanoCell TVS are LCDs and Have a Backlight
  • The Local Dimming Can be Bothersome (Too Bright or Too Dim)
  • Visuals “Wash Out” at Angles

QLED: What it is and what it means

Nanocell vs OLED vs QLED

The second technology applied to vision that we are going to analyze today is QLED. It does not use real lamps to produce light, and it is for this reason that it differs from the LED backlight system. In this case, in fact, the task is entirely entrusted to the so-called Quantum Dot technology (literally translated as Quantum Point); these are nothing more than semiconductor materials capable of emitting light, their size as in the case of the nanoparticles of TV Nanocell is infinitesimal. 

The main peculiarity of these quantum dots is the ability to produce light differently according to their size, the smaller they are and the more they will produce blue light; the larger they are, the more they will produce reddish light. The dimensions vary between 1 nanometer for quantum dots capable of emitting blue light, up to 3 nanometers in size for quantum dots capable of producing red light, and quantum dots capable of emitting green light are positioned on the 1.5 nanometers.

The main benefit deriving from the adoption of this technology is the very high brightness value that manage to reach the screens, and we know how it is one of the vital parameters to have a good TV. The direct consequence of a bright TV is the high contrast that it is able to achieve, even this aspect is in fact essential for having perfect images.

How should a QLED screen be cleaned?

As for Nanocell TVs, correct cleaning is essential for QLED TVs. The task to be performed is not complex but only needs some small recommendations. The first is to carry out the operation with the TV off, in this way we will be able to better check which areas need better cleaning. 

The second recommendation is to use a microfiber cloth, in this way we will avoid scratching the panel with materials that are too rough or too hard. The third and last tip is to use specific products for cleaning TV screens, which are easily purchased in electronics stores or online.

Who Makes QLED Screens?

QLED technology is one of the innovations that is having the most success on the television market, the merit is undoubtedly linked to the quality that the images are able to achieve. As a result, many multinationals are starting or have already invested in this technology. 

At the head of all there is undoubtedly Samsung , the South Korean production house has started producing this type of TV for some years and we are sure that it will continue to do so for a long time to come. Other manufacturers that have placed on the market models capable of supporting this technology are Hisense and TCL, two large Chinese multinationals that are enjoying considerable success also on the Italian market.

QLED Pros:

  • Eco-friendly product
  • Proven technology

QLED Cons:

  • High cost of production
  • Short life span of OLED materials

OLED: How it works

Nanocell vs OLED vs QLED

OLEDs have inherent characteristics that are unique to the TV screen landscape and are arguably the best technology to date. The abbreviation OLED comes from the English Organic Light Emitting Diode, which translated means Organic Diode capable of emitting light. And this is precisely the substantial difference between an OLED TV and a LED TV, if in fact the LED TV needs a real lamp to backlight the panel, the OLED TVs do not need it, in fact, they use Diodes formed from organic material that has the ability to emit its own light

The light emission mechanism occurs thanks to the presence of two elements, a cathode, and an anode, they are able to produce an electric charge which will interact with the organic material in such a way as to produce light.

The resulting advantages are many; the first among them is the depth of the black colors. In fact, being made up of “self-illuminating” diodes, OLED TVs will be able to switch off in such a way as not to emit light. LED TVs, on the other hand, will never be able to achieve such high black levels due to their lamp backlight system. 

The second aspect is undoubtedly the thinness of the screens, not requiring a backlight system the space needed to emit light will be much smaller than a normal TV that does not use this technology. Another better aspect is the viewing angle, in fact, it will be much wider than the competition. 

The only drawback is undoubtedly the price, being considerably advanced technologies are not within everyone’s reach, in fact, the costs can easily exceed a thousand euros for each TV.

Who Makes OLED Screens?

OLED technology represents a real turning point for the television market, and almost all manufacturers have not missed the chance to grab a slice of the market. The multinationals that have invested most in this technology are undoubtedly LG and Philips, which share a large part of the demand linked to the sale of this innovative type of system. 

As for the other houses we cannot fail to mention Sony and Panasonic, recently emerging multinationals such as Hisense is also throwing themselves into the OLED market. The only big brand that until now has completely snubbed this technology is Samsung, which has decided to invest heavily in other types of lighting, such as QLEDs.

How far is it to look at an OLED screen?

Buying an OLED TV is a real investment, and as such, it is right to think well about this action. Numerous e-mails from customers who are willing to make this substantial purchase but who have serious doubts about the correct positioning distance from an OLED screen reach our inbox. Nobody likes to spend thousands of euros in order not to make the most of such a jewel, so we believe that the question is more than legitimate.

However, it is important to point out that an OLED TV does not differ from a normal LED TVfor the viewing distance, what is right to keep in mind is the screen resolution. For every OLED on the market the resolution is 4K, and as such the rule of thumb is to place your new screen at a distance that varies between 1 and 1.5 times the size of the screen. (expressed in cm and not in inches). 

To give a practical example, let’s take a 55-inch OLED TV, the first operation to do is to multiply the value of the inches (55 in this case) by the fixed number 2.54; in this way, we will obtain the value expressed in cm of the diagonal of the screen or 139.7 cm. At this point, to make a correct positioning it will be enough that our screen is placed at a distance between 1 and 1.5 times this value, so we will have to put the OLED TV between 140 cm and 210 cm away from our point of vision.

OLED Pros:

  • Each Pixel is a Light Source, Extremely Dark Blacks
  • Very Vivid Colors & Image Quality
  • OLED is 4K Only
  • Great for Dark Rooms or Dimly Lit Areas
  • Perfect Visuals at Every Viewing Angle

OLED Cons:

  • Risk of Image “Burn-in”
  • Expensive
  • More Reflective
