Last year, the word "quantum dot" suddenly became hot in the television industry. First, TCL and Changhong introduced new TVs based on quantum dot technology, and Samsung and LG have also disclosed products using similar technologies at the CES Consumer Electronics Show in the United States. So, where is Quantum dot sacred and does TV consider it in 2017? On July 7th, at the launch of the latest issue of the GOME talk series, guests from the China Household Electrical Appliances Association, Gome, Samsung, TCL, etc. Focused on QDs, what impact QD TVs have on the television industry and what black technology is in the TV industry. What is Quantum TV? With the continuous improvement of the quality of content, people's display requirements for large-screen televisions are also increasing. Our common 720P and 1080P image quality can no longer meet the user's pursuit of content quality in the era of consumer upgrades. So 4K surges. Behind all this, it is actually the hardware producer television manufacturers are pushing. In order to enhance the picture quality of color TVs, manufacturers have never stopped in the display technology competition. What OLEDs, quantum dots, lasers, etc., people see dazzling, various technologies, various concepts are frequently fighting. Recent titles with "QD TV" often appear on the Internet. Many friends may think that this is a brand new thing like plasma TV. In fact, Quantum-dot TV is also a LCD TV. The biggest difference from LCD TVs in the past is that it uses a brand-new backlight technology. Based on this technology, the display quality of TVs has been significantly improved. Quantum-dot TVs use inorganic nanocrystalline quantum materials, and all quantum materials are nanoscale technologies. Quantum dots as a new type of fluorescent material, different from the traditional organic dye molecules, it can produce different colors of monochromatic light according to the size change, even white light, the emission spectrum has good monochromaticity and high stability. Since the popularity of flat-panel televisions began in 2006, LCD TVs have gradually eliminated CRT TVs, rear-projection TVs and plasma TVs with their industrial advantages. However, the problem of poor display of LCD televisions has been recognized. This is mainly due to the fact that compared with plasma: LCD TVs have low contrast (resulting in darkness is not deep enough), low color gamut (cause the color is not bright enough), and long response time (watching games) There will be smears.) Quantum-dot TV solves the problem of low color gamut among these three problems and surpasses plasma TV in one stroke. In fact, quantum dot display technology is being considered as the best solution for efficiently improving color gamut in the future. From the characteristics of quantum dots, we can know that using quantum materials, the purest light source can be amplified by different wavelengths to form the reddish red, the greenest green, and the bluest blue, and China generally adopts the United States. The standard, that is, the coverage of 72% of the color gamut required by all manufacturers is up to the standard, and color TV is also only possible for listing. Quantum technology can increase color gamut coverage from 72% to 110%. A common understanding is that display technology breaks through the traditional micron-to-nanoscale order and can bring more precise color control. In simple terms, quantum dot technology allows colors to be more pure, with a very small investment for better picture quality, the color of the TV being close to the colors of the natural world, and the lifetime of fluorescent materials is longer, without worrying about the lifetime of television products. As for why other manufacturers have only begun to push quantum dot technology, in the words of a TV industry person, they were busy promoting smart TVs in 2013 and 4K ultra-high-definition TVs in 2014... Until these two years, they were To quantum dots. The Quantum Dot Revolution started in television in the 21st century. With the rapid development of information, biotechnology, energy, environment, advanced manufacturing technology and national defense, the quantum dot revolution will inevitably put new demands on materials. Quantum dots have become a strategic technology of the 21st century and deserved to be One of the new cornerstones of basic science provides new solutions for material innovation. Some scholars predict that according to the unique photoelectric characteristics of quantum dots, its main application areas will first focus on electronics and optics. In fact, it is the television industry that has pioneered the field of quantum dot technology. In December 2014, the release of China's first Quantum-dot TV, the TCL H9700, not only confirmed the academic forecast but also ignited the development of quantum dots in the global television industry. "The reason why QD technology has made breakthroughs in the television field first and foremost lies in the fact that this technology can essentially enhance the TV display effect and thus attract the industry to conduct in-depth research on its technology." Point in the display technology as a star material prospects, all countries in the world are currently actively involved in research. It is reported that Sony's TRILUMINOS primary color display technology is the result of the use of quantum dot technology, South Korean media said that Samsung and LG's quantum dot TV technology is basically mature, ready for mass production. The domestic TV manufacturer TCL took the lead in the layout and promoted the landing of quantum dot products. In just over six months, QLED2.0, a second-generation quantum dot product, was released, enabling Quancai Quantum Dot Technology, 4000R gold curvature, and Dolby vision HDR. And wide color gamut technology upgrade breakthrough. "Quantum dots are one of the best solutions to enhance the color quality of television. The Quantum dot revolution started from the TV industry and has ample driving force for innovation." Industry sources stated that the application of quantum dot technology in the TV field has achieved 110% for the first time. NTSC's ultra-high color gamut, far more than the OLED color effect, broke the industry's myth that OLED is the only direction of the industry at one stroke, and it has proved more powerfully that the promotion of quantum dots, a basic material, has generated tremendous innovation thrusts for various industries. After nearly a year of development, quantum dot technology has changed the foundation for innovation in next-generation televisions and has become an industry consensus. Compared with OLEDs, which are also known as next-generation TVs, they are no less. 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. In addition, once the quantum dot is stimulated by electricity or light, a very pure and high-quality monochromatic light of various colors is emitted according to the diameter of the quantum dot, and the backlight using the quantum dot material is the most pure backlight of the current color. . Therefore, quantum dot TVs using quantum dot backlights have significantly improved color gamut values ​​and brightness, and can display more vivid and realistic colors. Even the most difficult to express red and green colors can be perfectly represented. “The transformation of quantum dots into the TV industry is not just a high color gamut, but more importantly a complete subversion of future TV formats.†Industry experts predict that breakthroughs in quantum dot technology will result in radical changes in the physical form of TV in the future. For example, by printing on a flexible object using inkjet printing technology, printing on a very thin, flexible or transparent substrate, completely changing the display device must rely on the limitations of the glass display substrate, so that the future TV form is ever-changing, arbitrary. Previously, the technology to change the form of television has always been a patent of OLED, and quantum dot technology is expected to break this monopoly in the future. Perhaps not long afterwards, the TV was not hung on the wall, but was rolled up on a post or stuck anywhere. People at that time could easily fold up the television, put it in their pockets, and "roll up and take it away" like a newspaper. The subversive changes that QDs have made to TV may be far more than that, but each one is enough to make people infinitely enchanted. Review: Those black technologies in the television field... Quantum-dot TV can be regarded as a black technology in the television field. As the technology matures, it will also enter millions of households. In fact, there are still more black technologies in the TV field. Today, we are taking a look at each one. Black Section 1: HDR HDR stands for High-Dynamic Range (High Dynamic Range), and the most important aspect of HDR for TV is to increase the brightness from 400 nits to 1,000 nits for normal TV. The increase in brightness can make the picture more realistic, especially for outdoor scenes. With HDR, the contrast and color accuracy of the picture can be greatly improved, bright parts of the picture will be clearer, dark parts will be more depth, and the appearance will be clear. The increase in color accuracy will make the colors look more pure and bright. In order to obtain a more pure display effect, a richer warm and cold alternation and a wider range of colors. Black Technology II: OLED Since the OLED has its own light emitting characteristics, red (R) and green (G) light will be generated under the blue LED backlight, and will be mixed with part of the blue light (B) through the film to obtain white light, thereby enhancing the entire LCD. The luminous effect of the backlight will increase the color gamut by more than 30%, making the color more vivid, and will not increase the thickness of the LCD panel. Black Technology III: IPS Although OLEDs and other new technologies are fierce, the dominance of the TV market is still IPS hard screen. IPS hard screen, as the standard of former high-end products, has significant advantages in terms of dynamic resolution, color reproduction accuracy, and viewing angle. At the same time, due to the unique horizontal molecular structure of IPS hard screens, it has no watermarks when touched. Shadow and flash phenomenon, the screen quality is extremely stable, life expectancy is also improved compared to soft-screen televisions, the theoretical use time is increased from 50,000 hours of soft screen to more than 70,000 hours.
