Quantum dots are composed of a finite number of atoms, and all three dimensions are on the order of nanometers. Quantum dots are generally spherical or spheroidal, and are made of semiconductor materials (usually composed of IIB-VIA or IIIA-VA elements) and have a stable diameter of 2-20 nm. Quantum dots are aggregates of atoms and molecules on the nanometer scale. They can be composed of a single semiconductor material, such as IIB.VIA elements (such as CdS, CdSe, CdTe, ZnSe, etc.) or IIIA.VA elements (such as InP). , InAs, etc.) may also consist of two or more semiconductor materials. As a novel semiconductor nanomaterial, quantum dots have many unique nano-properties.
What is Quantum TV?
Quantum-dot TV sounds very unpredictable, in fact, QLED TV is another name, QLED is "Quantum Dot Light-Emitting Diode" shorthand, Chinese translation is "quantum dot light-emitting diodes", which is a home appliance company looking forward to The new technology to replace OLEDs in the future is to irradiate red and green quantum dots of different diameters through blue backlights to form three primary colors of red, green and blue (RGB), and then form an image through an imaging system such as a filter film and a drive system. . To put it plainly, quantum dot TV is actually a kind of LED TV.
The advantages of Quantum TV:
Quantum-dot TVs have four major advantages: wider color gamut display, more precise color control, longer life, and greater energy efficiency. Since the quantum dots are stimulated by electricity or light, they emit a variety of different colors of very pure high-quality monochromatic light according to their diameters. This is even stronger than the OLED display. It is known that the OLED display is obtained through filters. Pure color, while the color through the filter is more pure, but there will be distortion, and the quantum dots do not need to be filtered, and this will not happen. At the same time, it can work at a lower voltage and energy consumption will be reduced to a minimum. In addition, since the inorganic materials used in quantum dot televisions are not easily oxidized, their imaging lifetime is 20,000 hours longer than that of OLEDs.
Quantum TV application:
Samsung KS9800 is Samsung's second-generation SUHD QD TV, quantum dot brings unlimited visual experience, almost unlimited color display, bright and bright light trigger, can be called a classic TV breakthrough. The design of the surface brings an immersive viewing experience and an immersive visual journey. Samsung's second-generation quantum dots have higher color purity and stability than the first generation. The color performance is also longer, and the lifetime is even more lasting. Not only that, it uses HDR1000 technology, the peak brightness of up to 1000 nits, regardless of over bright or dark areas, can easily show hidden movies. Thanks to the black-and-white anti-refraction technology of the moth eye, it reduces the reflection of the picture and is as clear as watching TV in the dark. 10-bit panel, color performance and traditional TV enhanced by 64 times, more realistic color reproduction. 360 ° ultra-thin design, ultra-narrow frame + brushed backplane, combined with a floating base, highlighting Samsung's exquisite beauty of craftsmanship, brings a strong style of simple technology. In terms of interfaces, the KS9800 provides four HDMI, three USB, one component input, one AV input, one LAN cable jack, one digital audio optical fiber output, and one radio interface, enough to handle high-end applications.
LeTV uMax85Q uses a quantum dot ultra-wide color gamut screen. The data show that it has 90% BT.2020 (CIE1976) color gamut coverage and 115% NTSC (CIE1931) gamut coverage, brightness can reach 1000 nits, and uMax85 is greater than The color gamut of the 90% DCI-P3 standard and the peak brightness of 800 nits have further improved the color gamut and brightness of the screen after the use of quantum dots. In addition, uMax85Q also supports Dolby Vision and HDR10 HDR modes.
TCL C2 is equipped with the world's most cutting-edge Yue Cai quantum dot display technology, achieving ultra-high 110% NTSC color gamut coverage, bringing the most pure color expression, breaking the traditional display technology color gamut ceiling, and fluorescence lifetime Longer, can greatly enhance the product's life. The award-winning TCL C2 TV, based on quantum dot technology, also incorporates full-ecology HDR technology to achieve a complete solution that fully meets the HDR standard for content, hardware, and software, and presents HDR images perfectly. At the same time, the moon shadow surface acoustics are also mounted synchronously, which brings a larger sound field resonance effect and realizes a powerful audio-visual enjoyment.
