In the field of smart TV, quantum dot TV has been developing rapidly with the help of traditional black household appliances such as samsung, TCL and hisense.Especially in the situation of the whole color TV market downturn, the quantum dot TV still has some growth, thus it can be seen that the quantum dot TV still has many advantages and characteristics that traditional TV can not match.But how much do you know about quantum dot TV?

Quantum dots are new semiconductor nanomaterials, made up of extremely tiny semiconductor nanocrystals that are invisible to the naked eye.Generally, quantum dots are composed of zinc, cadmium, selenium and sulfur atoms.The bell laboratories in 1983 for the first time, scientists studied the, after a few years of Yale university physicist, mark reed will officially named the semiconductor micro block "quantum dots" and used today.

As is known to all, in the microscopic physical level, the particles have many unique physical properties, quantum dots as nanoscale inorganic substance, has a distinctive features: when stimulated by light or electricity, a quantum dot will emit colored light, the color of the light is determined by the quantum dot shape the composition of the material and size, this feature enables the quantum dots to change the light source, light color.

Quantum dots to blu-ray completely into the white light LED source, rather like YAG phosphor can only absorb part of this means that under the same light bulb brightness, quantum dots LED lights need less blue, need less power nature in the electro-optical conversion, make it more efficient performance is better in terms of energy conservation and emissions reduction.

Quantum dot technology is used on TV, also has advantaged superiority, the backlight of ordinary LCD TV is pure white, and the backlight of quantum dot TV can display different color.Represented by samsung, TCL television manufacturers of quantum dots and television, through a quantum dot material added to the backlight module, can make TV brightness effectively increased 30% to 40%, significantly enhance back light color conversion efficiency is also at the same time, the color is more bright beautiful, purity was more than twice the normal LED TV, and has the characteristics of energy conservation and environmental protection.

For LCD TV, the brightness of backlight is an important index to measure the quality of TV quality, and the bright backlight can bring pure and bright color.The quantum dot TV can reach the peak brightness of over 1000 nit, not only make the TV show clear picture quality, but also show more hidden details in the dark part of the picture.

In addition, quantum dots TV very energy saving, compared with those of OLED TV quantum dots TV can even energy saving 50%, highest compared with LCD, is only about one over ten of the current power consumption.The reason for this advantage is that QLED electrons are more efficient at converting photons into photons.The same screen brightness, quantum dot TV natural energy consumption less.

Compared and brightness information, the color is easy to perceive the subtle changes of human eye, upgrade of quantum dots with TV backlight material, can achieve very wide color gamut range, cooperate with HDR effect, regardless of the brightness of the image information, the colour on the TV won't appear distortion.

TV in its development process, from the appearance point of view, the TV screen is more and more big, the thickness of the body is more and more thin, but its fundamental, TV is the root of the evolution from the TV back light brightness brought by the development of quality improvement.Only bright backlight can satisfy the demand of modern TV 4K, HDR and other technical characteristics.

To sum up, the advantages of quantum dot technology are "long, wide, pure and bright".Longer life respectively refers to materials (such as TCL using quantum dots material life up to 60000 hours), a wider color gamut (LCD color gamut can be 38% increased), colour more pure (display of red, green, blue three colors of the corresponding spectral peak clearer), higher brightness (a sharp rise in the LCD brightness).These advantages lead to a direct user experience improvement, the color of the TV is richer, cleaner, brighter, and even some experts believe that quantum dots show the ultimate visual experience possible.

The constantly upgraded TV form not only exceeded the imagination of the industry, but also broke the expectation of consumers for the future.Quantum dot TV also relies on the application of inorganic nanomaterials to bring more pure and bright colors to consumers and a natural view of the real world.
