TCL strong lead! Quantum dot display technology

From the "inherent thinking" of display industry development, most readers may think that the new era of display technology must be non-OLED is none other than, of course, OLED has many exciting physical properties, but there are also many difficult to resolve the ills to After so many years of high voices, it is still high and low. At the same time, quantum dot display technology emerged. TCL, the famous domestic TV brand, took the lead. Then TV brands such as Samsung and Hisense joined the quantum dot camp, which made people doubt whether OLED can dominate the future.

TCL has a strong lead! Quantum dot display technology
As the largest technology media in the country, the author first took a comprehensive and in-depth analysis of quantum dot display technology as early as more than two years ago: Changing the market landscape The new QLED display technology was fully analyzed. At that time, the author concluded that it was relatively immature. The OLED display technology, Quantum dot display technology more meet the commercial nature of many characteristics, if TV manufacturers do not follow up may be very passive. Is it still true today?

Professor of Zhejiang University and Senior Expert of Quantum Dots - Peng Xiaogang
On July 22, at the "Scientists Face to Face - Quantum Dots Display Science and Technology Popularity Forum" held in Hangzhou, Peng Xiaogang, a professor from Zhejiang University and a senior expert on quantum dots, gave an "affirmative" answer. This is an extremely important lesson. For quantum dot display technology with a more systematic and comprehensive cognition, quantum dot display technology has a promising future than we imagine. This potential is enough to subvert the perception of OLED display technology.

The best luminous material ever discovered by mankind
Quantum dot technology has many attractive features, such as color display, Professor Peng Xiaogang defined it as "the best luminescent material ever discovered by mankind". Quantum dots are solution semiconductor nanocrystals, and each small particle is a single crystal. Only about one ten-thousandth of the size of the hair. Only by changing the size of the quantum dots, you can get the desired color, and the color purity is very high, and the stability of the crystal is also very high. This is difficult for other materials, and there is no need to worry about the service life.

TCL has long since discovered the outstanding qualities of quantum dot display technology, coupled with its unlimited potential for development, so it has laid out QD TV strategy early and launched the world's first quantum dot TV product, leading the development of quantum dot TV industry. Subsequent support from TV brands such as Samsung and Hisense led Quantum Dot TV camps to grow to such an extent that they cannot be ignored. Among them, Samsung is directly giving up the OLED strategy, fully oriented to Quantum TV, and declared that "large-size OLED TVs have no future."

Quantum Dots Have the Opportunity for China to Lead the Display Industry

The advantages and applications of quantum dot display technology


In 2016, TCL's latest flagship TV product NTSC color gamut was as high as 110%, and the results measured by the instrument were also very close to 110%. Such excellent color performance pressures related OLED TV products, and also proved that quantum dot display technology is unique in terms of color. With its technological superiority, QDs display technology has an extraordinary significance today when all TV manufacturers re-developed their image quality as a development center.

The world's top chemist Peng Xiaogang - quantum dots can restore all the colors perceived by human eyes
The color gamut is a standard that determines how much color the human eye can observe. According to the highest BT2020 standard, Apple's iPhone is only about 50%, which means that half of the colors can't be displayed, but quantum dots can achieve 100% B2020 color gamut standard, and converted to NTSC color gamut is as high as 140%. All colors that the human eye can perceive.

Prof. Peng Xiaogang believes that “the improvement of color gamut is not only the increase of color, but also the tremendous improvement in texture and three-dimensionality of the picture. Quantum dot display technology has a natural viewing advantage.” In addition, Prof. Peng Xiaogang specifically pointed out that quantum dots The scope of application is extremely wide. At present, it is beginning to explore applications in the fields of solar cells, bio-medical markers, lighting and display industries, and has broad prospects. For example, in the field of biomedicine, quantum dots can be used to detect multiple pathogens or pesticide residues at the same time. Quantum dots can be used in the lighting industry to significantly increase luminous efficacy.


Quantum Dot Display Technology - Better Image Quality and Lower Power Consumption
In addition to unsurpassed color performance, stability, and no need to worry about the life of the problem, the performance of quantum dot display technology is far more powerful than the WLED backlight LCD TVs and OLED TVs, because the quantum dot luminous efficiency is extremely high, more important Quantum dots have the opportunity to allow China to lead the development of the entire display industry for the first time in the new era.

Breaking Foreign Monopoly - Quantum Dots Have the Opportunity for China to Lead the Display Industry

Display industry from CRT, to LCD, to OLED, core technology has always been in the hands of foreign giants, quantum dot display technology has been in the national "13th Five-Year Plan", led by Peng Xiaogang "QDs light-emitting display of key materials and devices "We have been selected as a key special item for strategic advanced electronic materials. With the joint efforts of countries, companies, and R&D institutions, China's quantum dot display technology will be expected to lead the world in new breakthroughs and lead the development of the entire display industry." This is what we are very much looking forward to.

Written in the end, may be a lot of diehard OLED fans believe that quantum dots are just the latest backlight technology of LCD TVs, it is difficult to achieve pure black, it is difficult to pose a threat to OLED display technology, do not worry, at this stage "photoluminescent" quantum dots do Can not leave the backlight system, but the next generation of "electroluminescence" is a revolutionary breakthrough, and soon we will share the future development direction of quantum dot display technology for you, and you will understand why TCL, Samsung, and Hisense TV giants love quantum dot display technology.
