OLED, QLED, NanoCell: what are they, what's the difference, which is better?

The difference between OLED, QLED and NanoCell TVs is in the technology behind the displays. QLED and NanoCell use an LED matrix and a separate backlight. In OLED, the backlighting comes from LEDs and does not require the installation of additional bulbs. What are the advantages and disadvantages of each of these technologies and which one is better?

NanoCell

LG does not disclose the secret of the technology of production of such displays. Experts believe that it's just IPS with an additional layer that absorbs light. It makes the color rendering better, because it filters out the dull colors. Brighter and cleaner shades are displayed. NanoCell embodies the main advantage of IPS - a wide viewing angle without color distortion and fading.

NanoCell is based on tiny crystals that emit clearly adjustable colors. This makes it possible to increase the brightness and clarity of the colors. NanoCell is a proprietary technology that only LG televisions use.

Advantages:

• Relatively low cost.
• High brightness.
• Rich color rendering.

Disadvantages:

• Low contrast.
• Obsolete basic technology.

QLED

Although the name is similar to OLED, but the technology in QLED TVs is significantly different. It is based on an LCD panel and a separate LED backlight. QLED displays have an LED matrix and are augmented with a color filter.

Advantages:

• Pure white color.
• High brightness of image - from 1500 nit.
• Wide choice of screen sizes - from 48 to 88 inches.

Disadvantages:

• The TV is thicker than models on other technologies in the same price range.
• The image can be too bright.

OLED

This technology is completely different from the previous two. It is based on organic LEDs that emit light. Additional backlighting is not used. Thanks to this the panel is very thin. Black is very saturated, because the pixels are simply turned off when you need to display that color. The other colors are rendered quite saturated. The brightness, although slightly lower than that of the NanoCell and QLED, but it is enough for comfortable viewing in daylight or electric light. Display of objects in motion is at a high level - no blurring or lags.

Advantages:

• OLED TVs are lighter and thinner.
• Contrast level is maximal.
• Objects on the screen do not have ghosting.

Disadvantages:

• Over time and with increased load, some pixels may display unevenly. Engineers can't yet fix this or fully compensate for it.
• The minimum size is 55 inches.
• The maximum brightness is not very high.

Which technology is better

It depends on the image requirements. If you need maximum brightness - QLED will give the highest figure. NanoCell TVs have a brightness of 300-400 nits, QLED has an average of 1500 nits. Color rendering is about the same for all three technologies. NanoCell slightly loses to competitors in color rendering. Black is the deepest in OLED matrix, respectively, the maximum contrast will be in these TVs. Viewing angle of OLED and NanoCell - 178 degrees, QLED less - 140 degrees.

In addition to high image quality, OLED TVs are the thinnest, but also the most expensive. NanoCell is a middle option between QLED and OLED for a lower price. The most budget-friendly TVs with the brightest image are QLED.
