QLED, OLED, IPS and NanoCell TVs – matrix difference, advantages and disadvantages, the best Smart TVs with each type of matrix. Each manufacturer introduces its own technology for manufacturing matrices with its own marketing names. Now it is difficult to understand how each screen differs from each other, but in fact it is not difficult to do. This article will discuss all types of matrices that are used in modern TVs and what is their difference. Let’s compare several TVs and give advice on choosing the best matrix.

What is a matrix on a TV and what functionality does it carry
The matrix is the screen that is responsible for the image feed. With the help of the matrix, the TV shows a color image and adjusts its backlight. The matrix consists of LEDs and a backlight layer, which makes the image visible. Each matrix works on the same principle, which uses RGB technology. If you decipher the abbreviation, you get Red, Green and Blue, that is, red, green and blue. It is with the help of these three colors that a full-fledged image is formed. If they are mixed in different proportions, then you can get any color in the spectrum available to the human eye.
The display has pixels that form the image. Each pixel contains one or more light bulbs of each RGB color. By changing the brightness of the diode, a pixel of a different color is obtained. There are a lot of such pixels on TVs, they are so small that when they work, we see familiar pictures. All matrices differ in the way the diodes are placed, the method of their illumination and the material of production. Basically, all TV screens are the same, they differ in the degree of brightness, the number of colors covered and the depth of black.
What are matrices and what is the difference
There are two main types of matrices, namely LCD (liquid crystal display) and OLED (organic light emitting diode). In turn, they are divided into many subspecies, which do not differ much from each other, but are made more for marketing.
IPS is one of the main representatives of LCD matrices. This technology has a large coverage of the color spectrum and a high viewing angle of up to 178 degrees. In TVs, an LED panel is used as a backlight, located under the diodes. Because of this, IPS matrices do not have deep blacks, since the entire display is backlit, regardless of color. Also, the main disadvantages include a low response time, but this is not essential for TVs, even if you play them in the console.
These matrices are the most expensive and are installed only in premium TVs. Due to the peculiarities of production, it is used only in large TVs 40 inches and above. OLED matrices use organic light-emitting diodes, each of them has its own backlight, from which the black depth tends to infinity. When a black area appears on the screen, the pixels in this place are completely turned off, from which the picture becomes very contrasting. In the picture below, an OLED matrix is \u200b\u200bleft, IPS is on the right. The difference on a black background is immediately visible.
Also, OLED matrices are distinguished by high brightness up to 4000 nits and high contrast.
The disadvantages include the way the brightness is adjusted. Pixels cannot change the brightness, so PWM technology is used to lower it. With it, the backlight starts to blink very quickly, but the human eye cannot perceive such a fast flicker, so it seems to us that the light has become dimmer. However, in fact, the backlight is always on at maximum, it just flickers at low brightness. Because of this, some people may have a headache when watching for a long time. Also, OLED matrices are more prone to pixel burn-in than usual. If the same image is displayed on the screen for a long period of time, then it may “freeze”. This happens after a few years of active use of OLED TVs, so they are not as durable as their LCD competitors. In modern TVs, manufacturers correct this defect in various ways, due to which the OLED matrix can work stably for up to 5 years. But sooner or later it will burn out anyway. This will not affect the operation of the screen in any way, just the colors will be slightly distorted, since some pixels will shine in a slightly different spectrum. You can see the difference in the picture below.
Despite the similar name, QLED is not related to OLED in any way. These are LCD matrices with improved backlight technology that uses quantum dots. They are close to OLED in image quality, but do not cost as much. QLED is very similar to IPS but has better contrast and deeper blacks (nearly close to 100%).
QLED is the marketing name for LCD panels that some companies like Samsung and TCL use in their devices. Other manufacturers such as Vizio and Hisense use quantum dot technology but do not use QLED in their marketing. To make things even more confusing, LG is releasing quantum dot TVs sold under the QNED brand. In fact, these are all LCD panels, which are very similar to IPS.
Postscript Neo is a new generation of LCD matrices with quantum dots for backlighting. This model differs from the usual QLED in reduced dots and a large number of them on one TV. Due to this, it turns out to improve the backlight, contrast and brightness. There are no big differences from QLED.

Nano Cell is the marketing name for displays from LG, which uses IPS technology at its core. That is, these are familiar LCD panels. The manufacturer takes the usual IPS-matrices, which are used everywhere, and adds another layer of light absorber. This results in improved color reproduction, increased contrast and increased dynamic range. In reality, there is no big difference from other LCD panels. https://gogosmart.ru/texnika/televizor/texnology/nanocel.html
What matrix production technology is the future
At their core, most TVs use LCD panels in their displays. They are inexpensive, high quality and bright. But there is already a completely new technology for the production of displays, namely OLED. These matrices do not need a separate backlight, which gives them higher contrast, infinitely deep blacks and the highest possible brightness. It is with this technology that all TVs will be produced in the future, especially when it will be possible to make their production not so expensive and get rid of the shortcomings of PWM. Already now, using the example of smartphones, in which OLED is becoming increasingly popular even in inexpensive versions, manufacturers are getting rid of the main disadvantages of organic LEDs.

Comparison of matrices on TV
Let’s summarize the comparison of all matrices in TVs using the table below.
|Matrix type||Description||Pros and cons|
|IPS||A popular LCD panel that is used in most inexpensive TVs. It has good color reproduction and viewing angles.||Pros: Low price. Large viewing angles. Quality color rendering. Cons: Low brightness. Low response. Black areas appear gray.|
|OLED||The most advanced technology in which LEDs have their own backlight. This allows you to achieve maximum contrast, perfect blacks and high brightness.||Pros: High contrast. Infinitely deep black. Highest brightness. Cons: High price. Flickering at low brightness. Pixel burn-in after about 5 years of TV operation.|
|QLED||Improved LCD panel with improved contrast and brightness.||Pros: Good contrast and brightness. Deep black color. Cons: Uneven illumination, especially in black areas.|
|Neo QLED||A new generation of QLED matrices, in which they made a more uniform backlight.||Pros: Good contrast and brightness. Deep black color. Cons: High price. Not perfect black compared to OLED.|
