The technology at the base of the tv neo qled samsung has been presented with expertise of details during an organized event for the specialized press. The topics dealt range from a study of the operation of mini leds to control through quantum matrix technology, then through artificial intelligence oata to optimize images and to apply upscaling. We see in detail all the insights provided by samsung:Summarythe advantages offered by the mini led quantumquantum mini led is the name chosen by samsung for its particular implementation of the backlight with mini led.

This type of diodes differs from conventional leds due to the much smaller size, generally between 100 and 200 micrometers. The mini led quantum are also characterized by a different structure: the systems with conventional backlight integrate leds that are first inserted into cells (to fix the leds in position) then covered with lenses that spread the light evenly across the screen. In the neo qled cells have been eliminated: what remains are small leds placed on a single extremely thin substrate to which the “micro layer” is combined which acts as a lens.

This conformation allows to reduce the ingot of the diodes up to a 1/40 compared to a conventional led (the comparison meter consists of the integrated leds in the qled 2020 series q80t). The full led arrays with local dimming (to deepen the theme we send readers to this article). The mini quantum led also allow to reduce the so-called “optical distance,” i.e.

The space between the layer containing the mini led backlight and the layer that spreads the light on the LCD screen. Why does this effect arise and how did it occur on the neo qled? In conventional led lcds the diodes spread the light evenly not only frontally but also towards the sides.

The emission generated by the structure with cells and lenses is therefore quite wide and this generates an overlap between the light coming from adjacent leds. With the quantum mini led the result is different thanks to the already mentioned micro layer. Overlap) between two adjacent blocks is considerably limited and the incidence of blooming can be effectively reduced.

As just described is schematized in the above figure: the graph in red shows the emission of the mini led quantum while the blue one is of a conventional led lcd. The emission width for the neo qled corresponds to 1/3 of that coming from traditional led cells. To better understand the difference, samsung provided an image showing the operation of the backlight in real usage conditions.

As you can see from the material attached to the article, the neo qled can more accurately represent all contours of the vehicle, highlighting a much more fine control of the backlight. The last improvement, in order of quotation, is inherent the luminous efficiency of the newly qled. This is how an increase in contrast ratio combined with a reduction in consumption.

La quantum matrix technology a 12-BITduring the event the first look 2021 samsung had talked about a 12-bit luminance scale for the neo qled range, but without providing a detailed explanation about it. It is appropriate to immediately clarify that we do not talk about native panels at 12-bit. The data is here referred to the control of the luminance that passes from the 10-bit of conventional leds to the 12-bit of mini leds.

When working at 10-bit, up to a maximum of 1,024 levels can be represented. With 12-bit control this value rises up to 4,0496 levels. The change, explained in these terms, can be guessed at the level of a simple numerical increment.

Quantum matrix technology offers greater granularity in the piloting of the mini led quantums. This means that when you have to show a source on screen you can count on multiple levels of intervention, for accuracy the quadruple. Let’s make an example: on TV you must represent a scene in hdr under conditions of high ambient brightness.

To do so, you need to increase the maximum power of the backlight to counter the light in the room. When you increase the upper end of the scale (the maximum brightness) you will inevitably act on the lower end (the level of black). This is where quantum matrix technology comes into play: the 4.096 levels allow to optimize the control of mini leds with more graduality.

Summarizing can be described the quantum matrix technology as the ability to represent all shades on the gray scale with greater precision and progressivisibility thanks to the background set with quantum mini led, local dimming, panel and electronics. Neo quantum processor: 16 models of neural networks for overscalingthe processing of signals on the neo qled is entrusted to the neo quantum processor equipped with artificial intelligence (ai). On the previous qled samsung managed the upscaling through the so-called machine learning super resolution (mlsr) based on a single neural network.

To these solutions were added to other more sophisticated thanks to the already mentioned deep learning. The purpose is to restore quality in the best possible way to approach that of an ultra hd or 8k native resolution video. Samsung summarizes these changes by talking about deep learning super resolution (dlsr).

Lower quality sources are processed by concentrating the action of algorithms on reducing blur, video noise and improving sharpness. In general all neural net models are however able to apply a better treatment of edges and textures. The ability of intervention of the neo quantum processor and various models of neural networks can be applied to any signal, from TV programs to streaming, passing through optical media.

The axe that equips TV samsung 2021 analyzes the image in real time, reaching to evaluate the frame by frame. Samsung argues that all steps are carried out while maintaining a more consistent screen output (with less obvious changes) than the previous generation. Contrast enhancement: the axe also optimizes contrastthe upscaling is not the only area on which the ace is able to intervene.

The Multi-Intelligence neural network can leverage the same 16 neural networks models to apply the contrast enhancement, a processing that controls the contrast ratio within each frame. We talk about the accuracy of algorithms that optimize the levels of luminance in the content, exploiting obviously the potential to ensure by quantum mini led and quantum matrix technology. For the neo quantum processor works by focusing on the visibility of the subject in the foreground: the level of black is lowered to make the dancer stand better than the background.

The news for video games with a look at the futureall new qled automatically select the auto game mode when console or pc are connected. This video setting has been modeled to ensure the best performance with video games and to pay special attention to reactivity to commands. The stated input lag is about 9,8 ms for ultra hd sources at 60 hz and 5,8 ms for ultra hd at 120 hz.

However, as we know, interpolation is one of the processes that could significantly impact input lag by delaying the response to commands. Factory calibration and expert optionsalso on the neo qled range is available the calibration made of synergy with the software calmn of portrait displays. The relations between the two companies are still consolidated since 2017, the year in which this possibility was introduced for the first time.

We close with ezcal, a function still in development presented for the first time last January to the ces. Via a simplified procedure you can get an effective adjustment by employing between 30 seconds and 15 minutes. The Korean colossus did not communicate well defined ocita times but confirmed the will to carry this function on their own televisions.

Come i tv microled2021 is the year when microled technology officially debuts in the TV market. The cuts from 99″ and 88″ have already been announced and later, again in 2021, will also arrive a 76.” The microled differ from any other type of TV for two reasons: they emit their own light and do not need color filters.

Light is diffused by tiny diodes (even smaller than mini leds): We find three for each pixel, one red, one green and one blue. Microled ensure a long life: samsung guarantees them for at least 100,000 hours with performances tendingly constant over time. Samsung talks about over a million levels for fine control of details on high and low lights (keys and darks).

The maximum brightness reached is double compared to previous generations of screens. The coverage of the color spaces DCI-P3 and adobe rgb reaches 100%. To offer an audio section at the height of the video was created the sound arena system, a 6.2.2 channel configuration with a central channel dedicated to dialogues.

From the neo qled TV range, the object tracking sound pro technology has been resumed, even here used to recreate an enveloping sound (even vertically) and to synchronize the sound with moving objects on screen. Those who want to further enhance the performance can use the μ-Symphony function (reciprove “Mew-Symphony”) to create a synergy between the internal speakers and a home cinema system. An official price list of microled TVs for Italy is not yet available.

But we know that we are talking about very important figures: in korea the equivalent of about 130,000 euros for 110 is required.”
