LG vs LG – сравниваем LED, OLED и SuperUHD

The choice of a modern TV set at first not seems to be difficult.

What? It seems like everything has already settled, smart functions and Internet access are everywhere, 4K resolution is almost everywhere, 3D isn't anywhere; choose your diagonal, price and go.

However, prices with the same diagonal are quite different, because the main difference is in the technology of the panel itself.

So, to which one should you give preference to? On the one hand, it would seem that everything is simple, there are no plasmas and old kinescope telephones, and everywhere is the absolute dominance of displays on LCD matrices.

On the other hand, these LCDs have already grown so many that a simple person can easily get confused in all these LCD, LED, OLED, QLED, SuperUHD and other clever abbreviations.

Fortunately, you have me for this, and today I'll try to explain in simple language the difference between them.

In total, there are three main categories.

The first, LCD TVs with LED-backlight: we will simply call them "LED" for brevity.

Already well-known technology, an LCD matrix with color pixels, behind which there are LEDs, highlighting the image.

The second is the recently appeared panels with the use of "nanocrystals" or "quantum dots".

Manufacturers like to call them Quantum LED or SuperUHD, but in fact, this is an improved version of the LED technology, with an additional filter in the matrix of tiny nanoparticles, which helps to improve the picture.

The third is a fashionable premium category based on organic LEDs, OLED.

Young, but very promising technology.

In these panels there is no backlighting as such, each pixel itself emits the desired color.

There is nothing ideal in the world; therefore each of the panels has its advantages and disadvantages.

Let's sort it all out and compare LED, SuperUHD and OLED on the basic parameters of image quality.

And that we are not accused of bias, let's do it on the example of TVs of one company – LG because in its lineup there are all three options.

We will have a LED model 55UK6750, SuperUHD – 65SK8500, and OLED – OLED55C7.

It's hard to convey on video, but on this parameter, OLED leaves competitors far behind.

Each pixel in the OLED panel is turned off individually, which allows it to be completely black, and as a result, the OLED picture has an ideal contrast.

LED and their quantum relatives cannot boast of such results, there is always a small parasitic light on a black background, and this is clearly seen when viewing in the dark.

However, the more expensive models of LED-TVs (and nowadays it's entirely Super UHD) have a system of local dimming and can dim the backlight on some part of the screen.

But here the account goes to tens, rarely – hundreds of zones, against eight million from OLED.

By this parameter, the good old LED TVs and their quantum SUHD brothers remain the leaders.

They have the great brightness; even top-end OLED-models are seriously inferior to them.

Actually, such transcendental values are required mainly for viewing in bright daylight conditions.

Yes, usually we watch TV, sitting right in front of it, but it does not always happen.

On LED-TV, the picture deteriorates if you deviate from the axis by an angle of more than 20-30 degrees.

Immediately, the contrast is affected and colors can be distorted.

At quantum models, this indicator is better, and at OLED the picture is practically ideal at viewing from any angle.

The accuracy of the reproduction of colors does not really have much to worry about; today all televisions are doing fine with this task.

If we talk about the numbers of precise measurements, then the TVs on quantum dots just by the filter with nanoparticles approach the color rendering to OLED but are still slightly inferior.

Unfortunately, there are still no displays with an ideal fill, if you display a gray background, then most likely you will notice the heterogeneity, dark and light spots, the so-called "dirty screen effect".

Moreover, this indicator also dances from the specimen to the specimen.

I am glad that you rarely notice this in life, mostly on various screensavers and sometimes on sports broadcasts.

And again here OLED shows itself better than other types of matrices, mainly thanks to the design without a backlit layer.

Different TVs convey the movements of objects on the screen differently.

Of course, very often this happens at the expense of any "smooth features", but even if you turn them off, you can see that some displays have the smeared picture which leaves trains, and others don't.

It depends on the speed of a response, the time for which each pixel can change the color to the desired one.

On this parameter OLED is again ahead of the whole planet, its pixels switch faster than normal matrices, and dynamic content on OLED looks better.

There is, however, a nuance, such "truthfulness of the transmission" can slightly "beat the eyes" on a video with a low frame rate, for example, a movie.

There are only 24 frames per second against the usual 50/60 television, and you'll notice a slight twitching.

On the other matrices, their relative "slowness" slightly smoothes the motion and compensates for this effect.

If you thought that eventually, OLED will win, then that's his Achilles heel.

OLED panels are more prone to the appearance of a residual image when a long-standing static object on the screen leaves a ghostly contour.

Although frankly, this effect can be achieved on LCD panels, it will just take more time.

Under normal conditions, this track "breaks up" after a while, and in the displays, there are several systems to prevent the appearance of such artifacts, but.



Nevertheless, if you watch the same channel 24 hours a day or play the same game for months, then there is a chance that the logo in the corner or the percentage of your character's health will remain on the screen for a long time.

You should better take LED or SuperUHD.

Initially, prices for OLED panels made unprepared buyers go for sedatives, but over the past year they have fallen dramatically and become available to enthusiasts who value the quality of the image.

TVs SuperUHD with quantum dots are not a cheap pleasure, top models start to prop up OLED from below.

But the old LED remains the most democratic; they exist with any diagonals and with any price tags.

Here were the pros and cons of each technology in brief.

You are free to draw your conclusions, but here you have mine, generalized ones.

If you have a limited budget, then choose LED.

If you are ready to pay more for a better picture and for days on end stick into video games, then your option is SuperUHD.

But the maximum achievable quality of the image you get today is only in one case, with OLED.

The choice is yours.

This was Katya, see you!.
