What is quantum dot TV?

Quantum dot TV sounds unfathomable, but it is actually another name for QLED TV. QLED is the abbreviation of "Quantum Dot Light Emitting Diode", which is translated into Chinese as "Quantum Dot Light Emitting Diode". This is a new technology, and home appliance manufacturers hope to replace organic light emitting diodes in the future. The principle is that red and green quantum dots with different diameters are irradiated by blue backlight, thus forming three primary colors of red, green and blue (RGB), and then forming an imaging system through a filter film.

Quantum dot is a kind of nano-material, and its particle size is between 2- 10 nm. When stimulated by electricity or light, the quantum dots will emit monochromatic light of different colors according to the diameter of the quantum dots, which can emit high-quality monochromatic red/green light with concentrated energy spectrum and very pure color, so the image is brighter and richer.

Quantum dot TV is a kind of LCD TV with quantum dot technology as backlight.

The main difference between LCD TV and traditional LCD TV is that different backlights are used, which brings many differences in performance. Compared with the traditional LCD TV with traditional LED backlight, it has more advantages in image quality, energy saving and environmental protection, and has become a new development direction of LCD TV in the industry.

Among many kinds, which display technology is better? Organic light emitting diodes and QLED (quantum dots) are often compared together because they have excellent color performance.

Organic light emitting diodes (OLEDs) Diode emitters are made of organic materials. Martin Saud, who owns dozens of patents on organic light-emitting diodes, said when asked whether LCD (liquid crystal display) would be replaced by organic light-emitting diodes (OLEDs), that the different lifetimes of the three luminescent materials of OLEDs were insurmountable fatal injuries. Quantum dot crystals are non-organic, so QLED works more stably and has a longer life.

Quantum dot TV uses blue LED as the light source, and optical materials using quantum dots are placed between the backlight and the liquid crystal panel, so that red, green and blue light with sharp peaks can obtain bright colors, and the color gamut reaches or exceeds the level of organic light emitting diodes.
