If the forecasts are met, the next edition of CES, which will begin on January 5, will be one of the most interesting in recent years. One of the reasons to look forward to this event is that we have strong reason to believe that Samsung will introduce its first televisions. equipped with a QD-OLED panel (Quantum Dot-OLED), which will allow this brand to compete head-to-head with LG in a market in which the latter has been at its best for almost a decade.

The South Korean media closely follows the steps that Samsung has taken in recent years. In 2019 they revealed that this company had begun to restructure its LCD panel factories to start production of QD-OLED matrices, and in recent months several Asian newspapers with a solid reputation have ensured that it was about to start large-scale production of these panels.

It is very reasonable to assume that Samsung Display will sell its QD-OLED panels to third parties, and the leaks ensure that Sony will bet on them in 2022

In any case, the juiciest information came just two weeks ago from BusinessKorea. And it is that this medium ensures that Samsung Display, which is the subsidiary specialized in the design and manufacture of panels of this latest Japanese company, will place on the market its first QD-OLED televisions with a panel manufactured by Samsung during the second half of 2022.

This is the formula for QD-OLED technology: quantum dots + OLED

The main advantage of the White OLED (W-OLED) panels manufactured by LG Display over conventional RGB OLEDs is that they do not suffer from premature degradation of the blue sub-pixel. What’s more, its production is simpler, cheap and allows you to obtain panels with a size significantly larger than that of RGB OLED panels. However, not all benefits.

The W-OLED technology requires the placement above the organic diode matrix of an RGB color filter that allows the reproduction of the three basic colors, but which, in exchange, absorbs light, significantly reducing the brightness delivery capacity of W-OLED panels compared to RGB OLEDs. And, in addition, its color reproduction capacity is inferior to that of this latest technology.

LG’s OLED TV panels have matured a lot since they first saw the light, and third generation matrices that we can currently find both in the G1 model of this brand and in the solutions of other manufacturers offer us an outstanding brightness delivery capacity and color reproduction.

In any case, the QD-OLED technology that Samsung is working on aspires to solve the two handicaps of W-OLED, but trying to keep its assets against RGB OLED. What Samsung is proposing is to replace the RGB filter required by W-OLED panels with a matrix of nanocrystals, or quantum dots, which is responsible for color reproduction.

Removing the RGB filter should allow the panel to deliver superior brightness delivery capability when measuring both the mean value and the peaks.

In theory removing the RGB filter should allow the panel to deliver superior brightness delivery capability both when measuring the mean value and the peaks. And, in addition, the nanocrystals should be able to reproduce a significantly larger color space than RGB color filter. However, the changes proposed by Samsung in the face of W-OLED technology do not end there.

Unlike the OLED panels of LG Display, which use white pixels, those of Samsung will use blue pixels, so that the nanocrystals will be responsible for acting on the blue light to generate the other two primary colors (Red and green). This transformation is possible thanks to a very interesting property of nanocrystals: their structure allows them to modify the wavelength of light, hence they manage to manipulate blue light to generate red and green light from it.

“Quantum dots” are a type of nanocrystals composed of semiconductor materials with very curious properties. And is that its size is so small that its behavior is described by the laws of quantum mechanics, and could not be explained using classical mechanics.

Their electronic characteristics are defined, on the one hand, by their size, and, on the other, by their shape, which explains why nanocrystals are currently being used for very different applicationsSuch as photovoltaic technology, biological labeling, pollutant removal technologies … And, of course, electronics.

For us, the most groundbreaking innovation in the field of large-format display devices is microLED technology.

The challenge during the quantum dot manufacturing process is to precisely control the size of the nanocrystals. In this way it is possible to get particles that shine in any shade of the visible light spectrum being excited by an electric current, colors among which are, of course, red, green and blue that we need to compose the color through an RGB panel like those used in televisions.

In our opinion the most groundbreaking innovation in the field of large format displays is microLED technology. We’ve already seen it in action, and it’s been available for months on some premium Samsung TVs that are priced out of reach for most users.

Precisely for this reason it is good news that while microLED televisions become cheaper, users have more options on the OLED battlefield. There is no doubt that the looming competition between LG and Samsung will cause the prices of these devices to fall, a trend that has been clearly consolidated over the last three years. And keep it up.
