Before the arrival of technology MicroLed, the only one that has proven capable of competing head-to-head with OLED panels from LG, the Korean firm has just presented within the framework of the fair Las Vegas CES his latest advances in image matters.
The first thing we have to know, so as not to get lost In a sea of acronyms that does not stop growing, there are two great families of technologies as far as TV is concerned. And those technologies have to do with the way in which the thousands of pixels into which the screen is divided are illuminated. To simplify, there are two types of pixels, those that illuminate themselves (self-emitting, with their own light source) and those that do not.
Traditionally, in most televisions the pixels are not self-emitting, and their illumination depends on a series of LEDs, which illuminate the screen either from a rear panel or from the side, from the frames.
In the OLED technologyHowever, developed by LG, no diodes are needed as the pixels light up by themselves each time they are needed. They are called ‘organic matrix pixels’ and have the advantage that they provide much sharper and more defined images, and much deeper blacks than any Led panel. The reason is obvious: it is not the same that the pixels light up one by one and only when they are needed to do so, inevitably, in groups because of the LEDs behind them. A rear diode, however tiny, cannot illuminate a single pixel, but several, and that translates into more blurred outlines. By not having rear lighting panels, in addition, OLED televisions can be much thinner and lighter than anyone with Led technology.
The arrival of the MicroLed, however, evened the board. Promoted mainly by Samsung, it is a technology that has achieved, for the first time, self-emitting LED pixels, that is, that light up one by one, just like OLED screens. And with the advantage, in addition, that since they are not organic, they do not end up degrading, as it does after many years of using OLED televisions.
For this reason, the news from LG in this edition of CES are important. Because they show that OLED technology is also continually evolving. And now it has done it again to continue maintaining the advantage it already had, with the best images that can be seen on a television. Thus, for example, to the G2 series, which until now had 55, 65 and 77-inch OLED screens, now adds an 83-inch model and a real 97-inch ‘monster’, the first OLED of that size of the world. And the C2 series, for its part, grows ‘below’ by introducing the world’s first 42-inch OLED TV, which joins those of 48, 55, 65, 77 and 83 inches. Both series incorporate the new OLED evo technology, in which the 5th generation α9 (Alpha 9) processor is able to obtain even more brightness and contrast than previous models thanks to Artificial Intelligence, which improves image quality (and also of sound), in real time.
LG QNED, the intermediate step
Of course, LG also sells Led televisions, and it must be said that the latest technologies available in terms of non-self-emitting pixels (which do not illuminate themselves) have managed to approach, although not exceed, the quality of OLEDs. In fact, the new LG QNED Mini LED presented this year at CES could be considered, in terms of quality, as an intermediate step between Led and OLED televisions. Something that is achieved, once again, with the help of artificial intelligence.
QNED stands for ‘Quantum Nano Emitting Diode’, which means that the size of the diodes has been reduced so much that a much larger number of them can be placed on the lighting panel, allowing the screen to be divided into thousands of individual zones (instead hundreds) that can be controlled independently. This control of multiple individual zones results in a significant improvement in both color and contrast.
Therefore, the new generation of LG QNED Mini Led televisions is a high-quality alternative at lower prices to OLED televisions.
