7 new technology trends affecting LED in 2020
Micro LED can combine different display backplanes to create transparent, projection, curved, flexible and other display effects, and has higher electro-optical conversion efficiency, low power consumption, good stability, long service life, no size development restrictions, super fast Switching time and other advantages.
With the development of 5G, the entry of Micro LED not only improves the dynamic performance of mobile phones, but also opens up the application of mobile phones in AR and other fields. In addition, in terms of the hottest gaming applications, in addition to high-refresh frequency panels, higher-end products with Mini LED backlight to enhance the contrast performance, the conditions for mass production are becoming more and more abundant.
Although the cost of Micro LED remains high in the short term, there are still more and more panel manufacturers launching Micro LED and Mini LED solutions. It is likely to create a new blue ocean market in 2020.
The Internet of Things and smart lighting have reached the current stage, and DALI, ZigBee, Bluetooth, Wi-Fi, LoRa, NB-IoT, Sigfox, Z-wave, EnOcean and other various communication technologies have emerged in the market. Not only can you get higher profit margins, but also an excellent access point for smart cities.
Many low-power wide-area networks (LPWAN) designed for low-bandwidth, low-power, long-distance, and massively connected IoT applications have emerged. NB-IoT using licensed spectrum, and LoRa (Long Range) and Sigfox using unlicensed spectrum have become mainstream among them.
Smart Laser Light
The current mainstream types of lights are: halogen, xenon, LED, laser. Who is the better? BMW believes that the future is the era of laser headlights.
Compared with LED headlights, the length of a single laser diode element can reach 10 microns, which is expected to bring revolutionary changes to the front face design of a car; the luminous efficiency of laser diode elements can reach 170 lumens per watt, which is about 1.7 for LED lighting Times.
The laser headlight can reach a range of 600 meters in front, which is about twice that of the LED high beam, which provides better safety guarantee for driving.
At the end of November 2019, the National Health Foundation (NSF International) updated drinking water treatment standards and formulated new standards for the use of UV LED technology.
Treatment systems included in the standard use UV light to kill bacteria, viruses, and parasite spores in microbial unsafe water (Class A systems), or to reduce the number of non-pathogenic bacteria in sterilized drinking water (Class B systems) .
According to the data from the LED research center of State Consulting Group: The output value of the UV LED market is expected to reach USD 1.224 billion in 2022, and the compound growth rate in 2017-2022 will reach 33%.
UV LEDs are gaining more and more applications, from water, air, and surface disinfection to medical diagnostics, phototherapy, and curing of various materials.
In the future, people will increasingly rely on mobile digital products such as smart phones and smart watches, and personal privacy and the security of sensitive data will become increasingly important.
Various biometric-based protection measures will emerge as the times require, providing users with a solid "lock" to protect them from unauthorized access.
Recently, Osram launched the smallest new type of infrared LED (IRED) biometric products, which not only helps mobile device manufacturers solve data reliability and security issues, but also provides more imagination for product design.
IRED can be more flexibly integrated into customers 'terminal equipment, which is not only safe, reliable, saves more space, but also effectively protects users' sensitive data.
Although there are still uncertainties in the market this year, the new industry such as 5G, AI, and automotive support will drive the semiconductor industry gradually out of the bottom.
IC design industry will introduce a new generation of intellectual property rights, strengthen ASIC and chip customization capabilities, third-generation semiconductor materials such as SiC, GaN and GaAs, etc., with characteristics such as high voltage resistance, low impedance and fast switching speed. Applications such as cars have received much attention.
At the same time, due to chip line width scaling and improved computing performance, advanced packaging technology has gradually evolved toward SiP (system-in-package). Compared to SoCs (system-on-chips), SiP's composition structure is more flexible and has cost advantages, which is more in line with Demand for AI, 5G and automotive chips.
In 2019, the battery cell format changes and the development of micro-technology on the component side are diversified, including the use of various technologies such as half-chip, patch, laminated (watt), multi-grid, double-glass, double-sided (battery) modules.
In 2020, the core competitiveness of photovoltaic module products will gradually depend on the cost of electricity: improve battery efficiency and module power to create greater power generation and ensure long-term reliability of the product. The right to speak of product pricing in the future market will no longer be controlled by the manufacturing end, but will be determined by market demand and buyer acceptance.
