What is quantum dot technology on TV? Whether to buy or not?

Manufacturers integrate many advanced and modern technologies for new TV lines, including quantum dot technology. Let’s find out through the following article to better understand quantum dot technology in TV screens!

What is quantum dot technology?

Quantum dots are microscopic particles that are counted in atoms, allowing TVs to display a wider range of colors. Quantum dot panels will have 50% wider color gamut than conventional LCD technology.

In conventional LCD and LED screens, the color is determined by a filter, which does not produce completely accurate colors.

With quantum dots, the smallest particles always emit blue, the larger particles are green, and the largest particles will emit red to display the color range for televisions.

Outstanding features of quantum dot technology

The maximum brightness of the screen is higher

One of the reasons TV manufacturers choose quantum dot technologies is because they allow them to produce TVs with much higher maximum brightness. This also opens up some interesting possibilities, such as allowing HDR TVs to support Dolby Vision technology.

Dolby Vision is a technology that brings visual content with color to life lifelike and higher contrast than current standards.

Better color accuracy

Another big benefit of quantum dots is improved color accuracy. The light produced by quantum dots is related to their size.

This has been extremely precisely tuned by TV manufacturers to produce the right kind of light needed, resulting in purer, brighter and more accurate colors for the television.

Greater color detail

An advantage, although it can also be called a disadvantage in some cases of OLED screens over LCD screens is color saturation.

Colors on OLED screens are simply more “pop” thanks to the huge range of colors that the display can achieve. However, quantum dots can increase the color range on LCD screens to about 40% – 50% .

Quantum dot TV is a great combination of high color range and color accuracy. This combination brings the ability to display HDR on LCD TVs with very good quality.

Should I buy a TV with quantum dot technology?

The answer would be Yes . In fact, quantum dots are a much more exciting development than 4K televisions in a few respects.

While sharper images are certainly great, the dynamic contrast that makes the difference between the lightest and darkest parts of an image has a huge impact on the viewer’s experience.

Quantum dots give LCD TVs high contrast and color depth to enhance our viewing experience. So the next time you buy an LCD TV, buy one with quantum dot technology.

TV manufacturers that use quantum dots

Quantum dot technology has been applied by many TV companies to their products, each with different names. Such as:

• LG calls this product Nanocell TV.

Nanocell is a technology capable of absorbing light wavelengths that are considered redundant, to improve the purity of the screen, providing a great user experience.

Nanocell technology on LG TVs uses microcrystalline particles with a diameter of only about 1 nm (nanometers) capable of accurately reproducing colors. In addition, it enhances the detail and purity of the images presented on the screen.

• Sony calls this product TRILUMINOS .

Sony’s TRILUMINOS™ Display technology uses the action of quantum dots, which help create a wide array of colors, to give viewers rich and natural colors.

Specifically, the white backlight will be replaced by a blue LED that helps emit blue light, passing through a filter made of quantum dots. Quantum dots will emit light according to each wavelength and create different colors on the screen.

• Samsung calls this product a QLED TV .

QLED TVs work by placing a magnetic dot layer in front of the LED backlight layer. These dots are used to display images because of their ability to give different colors depending on the size of the dots, can emit their own colors and be reproduced in more detail.

Quantum dot panels will have 50% wider color gamut than conventional LCD technology. On QLED TVs with thousands of microscopic quantum dots, each color level will be clearly represented, providing images with more accurate colors and clearer contrast.
