LED display technology dynamic quantum dot lighting product release

innovation is almost a household word in the business world. In the west, more than 60% of the S & P 500 companies integrate "innovation" into their corporate mission and deliberately use the word "innovation" in marketing and brand promotion. Similarly, innovation is also an important "vitality" for the development of LED display industry

previously, in an interview with the media, Jiang Fengyi, an expert in the field of LED, said that China's LED technology and industry have developed rapidly, and both technology and industry have entered the world's advanced ranks. So, what is the current development of LED technology

release of the first quantum dot lighting product

recently, the world's First Symposium on the release and application of quantum dot microsphere LED products was held in Tianjin, a beautiful city around the Bohai Sea. At the meeting, different types of quantum dot packaging devices and quantum dot lighting products were released around quantum dot microsphere materials

Tianjin Zhonghuan Quantum Technology Co., Ltd., the publisher of quantum dot fluorescent microsphere materials, can make products into plates, profiles, sheets, pipes and other companies, and is committed to the research and development of nanocrystalline materials and composites. At present, it has many international and domestic leading patented technologies, such as qlms, quantum dot + (qd+), QD Alef, hb-qled and so on. With this material as the core, Zhonghuan lighting has launched LED packaging devices based on composite quantum fluorescent materials and high-quality and high color rendering quantum dot lighting products

at the press conference, Tianjin Zhonghuan electronic lighting technology Co., Ltd. released the quantum dot backlight device relying on the world-class innovative quantum dot microsphere Technology (qlumis) and the first qled high color rendering lighting table lamp using quantum dot packaging devices

Tianjin Zhonghuan electronic lighting technology Co., Ltd. introduced the quantum dot LED packaging device for the first time. This device has the characteristics of wide color gamut, low power consumption and low cost, and is the key of the next generation led display technology. The device provides excellent characteristics such as high color gamut comparable to OLED technology in the field of liquid crystal display, and will be a key device for the performance upgrading of domestic mature liquid crystal display products. At the meeting, a sample of using this technology device as a backlight was displayed. Its display effect is significantly better than that of traditional LED devices as backlights, and can be comparable to the display effect of OLED screens. According to the enterprise, because it does not need to make significant changes to the traditional product structure, and the manufacturing cost of devices is far lower than OLED devices, the cost of high gamut display screen will be greatly reduced in the future, so that more mobile terminal devices including it can achieve the display effect of high gamut at low cost

the first quantum dot lighting product was also introduced at the meeting. Relying on quantum dot LED packaging devices, the product has the core advantage of high color rendering index (RA 95, R9 95), and realizes the balance of red, green and blue light. At the same time, the product improves the accurate interpretation of different colors, enhances the recognition of edge contour, and essentially improves the lighting effect of lamps and lanterns from the light source. The quantum dot table lamp launched this time has a differentiated appearance design for different user groups, especially for the actual simulation of the use environment of primary and secondary school students' writing and reading, teenagers' desktop lighting and high-end business people, which improves the user experience from the details

Ms. Guan Baiyu, Secretary General of China semiconductor lighting/led industry and application alliance, said that China's LED industry has achieved rapid development in the field of LCD backlight and semiconductor lighting in recent ten years, with the continuous expansion of industrial scale and the rapid improvement of technological innovation ability. In the process of rapid industrial development, more independent innovative materials are needed to support the development of China's LED industry. Through participating in the release of quantum dot microsphere (qlumis) technology and products, we can see that the quantum dot microsphere of Tianjin Zhonghuan Quantum Technology Co., Ltd., as one of the core new materials in the field of LED packaging materials, provides new innovative materials for the improvement of LED performance, and is at the forefront of innovation. It is hoped that Zhonghuan will continue to do a good job in R & D and application promotion, so that high-performance materials with independent intellectual property rights can be applied to more product fields

important progress has been made in semiconductor gated quantum dots for two-dimensional materials

the Key Laboratory of quantum information of the Chinese Academy of Sciences, led by academician Guo guangcan of the University of science and technology of China, has recently made important progress in the research of semiconductor gated quantum dots. Professor guoguoping's research team in the laboratory and its collaborators have explored the possibility of applying two-dimensional layered transition metal chalcogenides to semiconductor quantum chips. In the experiment, a fully electrically regulated quantum dot device has been realized in a flexible two-dimensional semiconductor material system for the first time

after decades of development, semiconductor gated quantum dots, as a kind of quantum transistors, have become one of the popular candidate systems for quantum chips. The two-dimensional material system represented by graphene has become the key research object of flexible electronics and quantum electronics because of its natural monatomic layer thickness, excellent electrical properties, easy integration and other advantages. However, in the more than ten years since graphene was discovered, scientists have found that the energy band structure, interface defects and impurities in graphene have a great impact on the performance of quantum dot devices. Until now, quantum dots in two-dimensional materials have not been able to achieve effective electrical regulation

in view of this situation, Guo Guoping's research team, in cooperation with researchers Takashi Taniguchi and Kenji Watanabe of the National Institute of materials of Japan and Professor Franco nori of the Institute of physics and chemistry, has pushed the external wall insulation material to the forefront of the storm and selected a new two-dimensional material molybdenum disulfide for in-depth research. This material has suitable band gap, strong spin orbit coupling strength and rich spin Valley related physical phenomena, so it has broad application prospects in quantum electronics, especially spintronics and energy Valley electronics

after a lot of attempts, the research group used a series of modern semiconductor technology means such as micro nano processing and low-temperature led irradiation, combined with the boron nitride packaging technology widely used in the current two-dimensional material system research, effectively reduced the impurities and defects in the quantum dot structure, and realized the fully electrically controllable double quantum dot structure in this kind of material for the first time

with micro LED screen, Google ar glasses may return

according to techradar, Google ar glasses have returned in some form in recent months, but the new glasses have made some modifications to target enterprise users. AR is rising again, and Google may invest again. In March 2016, Google applied for a patent. Judging from the patent, the fully modified hardware may appear again

the device described in the patent is a spectacle frame device, which uses a miniature led transparent display screen to display ar information to users

there is a serious problem with Google glasses initially launched: the display is installed on a glass prism, which is located in the wearer's natural 4 Whether the friction of the experimental machine increases; Outside the field of vision, users must look up to see the information, which is very uncomfortable and easy to be distracted

The device shown in the patent displays information in front of two eyes instead of one. In this way, the rendered image is deeper. The patent also suggests that micro LEDs can be converted between transparent and opaque modes to display AR and VR applications respectively. Google's technology can also be used on other devices

it's interesting that Google actually uses micro LED screens, because Apple bought a company called luxvue, which is the main micro led company. There are rumors that apple is developing ar glasses. It seems that the two companies coincide in the AR wearing architecture. The puzzle of smart glasses has gradually become clear

Apple layout micro led

according to Appleinsider, a foreign science and technology station, apple actively layout micro LED technology, which is expected to be applied to new Apple watch products in the future and extend the battery life. The report pointed out that if the future Apple watch uses micro LED panels, it can be charged overnight

patently apple, a foreign science and technology station, reported that an apple patented application related to micro LED has surfaced, using smart pixel controller technology to control the LED pixel driving the display screen, which will have the opportunity to be applied to IMAC computers, iPhones or apple TVs in the future

the Nikkei Asian review previously quoted industry sources as saying that Apple plans to use micro LED panels in its wearables as soon as 2018. Media recently reported that from the perspective of market speculation, Apple may test produce micro LED screen products in Taoyuan, Taiwan at the end of this year

patently Apple previously reported that Apple has developed a screen design trend of HMD (head mounted display) with headphones, gradually moving towards micro led

the report points out that the head mounted display screen with micro LED panel only needs about 10% of the power of the head mounted display screen with LCD panel in the near future to operate, and the power consumption is only 10% of that of LCD. The power saving effect is quite significant, and it can expand game applications, and can also become a peripheral device of iPad or iPhone

Shenzhen LED intelligent street lights first appeared on the street

recently, at the entrance of Shenzhen Shahe West Road to Shenzhen Bay science and technology ecological park, two road light poles with a sense of science and technology have been set up. This road light pole is called "smart road common pole", which combines multiple poles and has powerful functions ~! The equipment is inside the pole, which can't be seen by outsiders. It is called the invisible "Iron Man" in the street lamp pole by the industry. The future road of wisdom can achieve almost all functions with only one pole

1. WiFi connection: within 50 meters of the light pole, citizens can access Wi Fi for free. 2. Display time, parking space and road conditions: the lamp post is equipped with an LED display screen, which can scroll the surrounding road conditions, travel time, surrounding parking spaces, weather conditions and other travel information in real time

3. Alarm: an alarm is configured on the lamp pole, which can be used for alarm call in case of emergency. In addition to providing all kinds of transportation information and services for citizens, the function of smart road common pole is far more than that. Taking the street lamp pole as the hardware carrier, it also integrates 23 kinds of sensor devices such as video, DSRC, IOT relay, WiFi probe, environmental detector, and supports the functions of road panoramic monitoring, traffic operation monitoring, road danger early warning, vehicle road collaborative control, intelligent directional guidance, and IOT of equipment along the line
