L.G advertises its mid-range televisions as nano-cell LCD televisions. In terms of price, they are between the cheapest LCD TVs and the outstanding OLED TVs. But what does nano-cell actually mean? And is it worth the extra charge compared to normal LCD televisions? The COMPUTER BILD test answers these questions.
LG TVs: That means Nano Cell
Every LCD screen is made up of several layers: From the viewer’s point of view, at the very back is what is known as the backlight – a light source as large as the entire screen, consisting of white LEDs. That is why LCD televisions are also known as LED televisions. The next layer is the LCD panel as the actual image-generating element. You can imagine it like a huge black and white slide. What should later be dark in the picture is opaque. Bright parts of the picture allow light from the backlight to pass through unhindered. A color filter as the third and front layer turns the black and white views into colorful pictures. And this is where LG’s nano-cell technology comes in: the more precisely these filters filter out pure red, blue and green, the more colors the television displays overall. It’s like with the paint box: only with clean paint pots can pictures be bright Brush colors.
LG Nano816NA in the test: the picture quality is so good
Local dimming for higher contrast
The maximum brightness achieved in the test was also remarkable at almost 500 candelas per square meter (nits). Only with the deepest black the LG does not have it, it shows it in dark gray at most. As a result, the images lack plasticity, especially in dark surroundings. LG wants to counteract this with a partially dimmed backlight. The light source behind the LCD panel is only divided into a meager six vertical zones that can shine with different levels of brightness. This causes more irritation with halos and brightening than it improves the contrast impression. The somewhat poor contrast is typical for LCD screens with so-called IPS technology, which, on the other hand, offers great viewing angle stability or wide viewing angles. So if you don’t sit straight in front of the TV, but watch it a little sideways, you can still enjoy the brilliant colors.
