Analysis of the five major directions of LEDs in development of market

“The LED is divided into upstream and downstream, which can be said to be a dragon. For new technology development, in the collation in the top and bottom, Ronda has certain advantages over other separate parts. The leading differences are getting smaller and smaller, but it is only the advantage from a single layer, but if the integrated advantage point of view, the advantage of Ronda’s one -stop is more obvious.

In recent years, the explosive rise of LEDs in mainland China has become more and more impact on the entire Taiwan and the global LED industry. The international LED manufacturers have adjusted their strategies, and shifted from early production to the mainland foundry. The industrial change pattern is reshaped. As a representative of Taiwan’s LED enterprises, Da Liang Electronics, except for the one -stop corporate model, how does Electronics company lay out the future to cope with the current LED environment?

Micro LED: MINI LED first goes back to the backlight commercialization, Micro LED is still a bit far away
In the past two years, giants such as Apple, Facebook, Google, and Hon Hai have deployed Micro LEDs, so that LED companies have seen new market opportunities. Especially when Taiwan is constantly snatching the share by the mainland, the appearance of Micro LED has made LED companies to design the new machine.

However, many LED companies in Taiwan have participated in in the past two years, but they have not been able to make breakthroughs in huge transfer. This makes LED companies discover Mini LED. According to survey, it was MicroLED at first, but MicroLED can only break through in the sample stage, and it needs to break through in technology and equipment.

The OLED screen used in mobile phones is nothing more than highly contrast and bright color, which can be thin and thin. The MINI LED is better than OLED for backlight than OLED, and it can also be thinner. The key is that the technical difficulty is small, and the MINI LED response speed is very fast, the power saving effect is very good, and it may be achieved within one year. In addition, the market will improve from Mini LED to Micro LED in the future, and then develop Micro LED display modules, which will be able to do small size for LCD and OLEDs. Because Micro LED module can stitch extension, it is a very promising trend for LED.

IR LED: Benefiting iris, faces and unwanted light sensing explosion, the potential is unlimited
With the rise of modern IoT, biometrics, and wearable devices, the more important the various sensors and image recognition technology are. The application characteristics of IRLED have become important auxiliary light sources. And after combining sensor devices and identification technologies, special applications such as iris recognition and face recognition can be applied. Or it can be used on the biosensor that is applied to the wearable device, which can quantify the physiological state of the human body and become a new tool for health management. In view of the surge in the penetration rate of smartphones, cars, monitoring systems, and other applications, IR LEDs that continue to heat up the IR LED market have received more and more attention.

At present, IR LED is mainly used in the field of safety monitoring and sensors, and uses the wavelength of 850nm and 940nm LED products as the community. In response to the emergence of iris recognition applications, each LED factory competes with IR LED products with a wavelength of 810nm in order to attack the market to attack the market Business. According to an electronics, the company’s products have now entered mass production.

IR LED used to be small and medium -sized power, but now it is used in mobile iris and face recognition. These are high -power, and the wavelength is also special. However, regardless of security or face recognition, blood sample testing or industrial 4.0 automation equipment, it is related to IR. The image recognition of the device now uses infrared, which is inseparable from the sensor and light, but it is independent of the sensor and light. Unlike the visible light sensor, it is now an invisible light sensor. This requires a good light source to go Only by making lighting controls, you can realize some programs, so the potential of IR LED is very great.

LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84,  CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, COMMISSION DELEGATED REGULATION (EU) 2019/2015, IESNA LM-63-2, IES-LM-80 and ANSI-C78.377, it recommends to using an array spectroradiometer with an integrating sphere to test SSL products.

UV LED: The curing market has matured, and the deep layout UVC LED
Because of the impact of the mainland LED supply chain, Taiwan’s LED companies have pursued the high gross profit market. Among them, the UV LED market has performed the most prominent performance. As a large LED factory, some electronic factories have always been actively deploying the development of emerging markets. At present, the UV business is also conducted by the market trend.

Generally speaking, the application of traditional UVA bands is mostly industrial solidification, and high -power module applications such as exposure. At present, some electronics company has cooperated with large domestic and foreign factories, mature, and some large factories are more active towards deep ultraviolet UVC bands to solve the solution The plan to achieve the goal of planning a full -band of UVs for one stop will be for future product planning.

Pour chip: The high -power market has increased significantly, and the medium -power market is gradually eating
Early pour vertical was done by large foreign factories. About two or three years ago, both the mainland and Taiwan have obviously made a significant breakthrough in technology. The architecture of the inverted chip is different from the formal dress. Generally, only 4-5 processes are required for formal installations, and 7 processes are needed for pouring. The process has increased by 2-3 more. So the current price is relatively high.

But now the inverted chip starts to enter the mid-power market, about 0.3-0.5W. In the past, the chip was 1-6W high power. Now starting, this means that the cost is controlled to a certain amount of control, and the distance is narrowing. In addition, the advantages of inverted loading are obvious. Not only have the voltage advantage, but also the inverted chip can do some film processes, which can improve efficiency. One of engineer said that it is difficult to erode the entire mid -power market this year or next year, the main reason is the price. Because in the same performance, the current pour chip still cannot catch up with the cost -effectiveness of the formal dress.

CSP: Backlight of high power positioning, low -power positioning lighting market
Because CSP technology is reduced or even removed, the packaging cost is reduced, and it has the advantages of glowing appearance and better heat dissipation function. However, although it is very attractive in many applications, it is more fragile than that of its small chip, high accuracy of patch equipment, and no brackets. Generally packaging is high, and the technical capabilities of the upper and middle -down LEDs need to be integrated.

The current CSP structure is a inverted chip+fluorescent glue, and then there is a white wall and a change in the substrate. In the past two years, there are many companies talking about CSP, but there are not much contribution to the actual turnover. The reason is that the lighting packaging device must be cost -effective whether it is lighting or backlight.

In terms of lighting, CSP has EMC and COB in high -level applications, and 2835, 3030 in low power. There are many competitive products alone. Generally, the inverted chip is limited to high -power applications, and there is no advantage in small -power cost performance.

Therefore, there is a problem with the positioning of the positioning of this product itself, but the application of the backlight is excellent. That is because the application of the backlight is a high power, so the application of the backlight is capable and mature. So in terms of lighting, the LM/W performance for CSP is not good enough, and the price is expensive. Some electronics companies have designed CSP products with small and medium -sized power, which highlights its advantages.

According to the survey, another trend of LED in the field of lighting is to improve the quality of light. LEDs can already achieve a very good life and cost. The next stage is to pursue perfect light quality. This part of blue to green is relatively lacking. It is more likely to have the feeling of poor light source and color offset. The 2018 fast LED explicit fingers will be pushed from 80 to 90. This technology can be encapsulated in various packaging. The form of form and full -color temperature is called “Solar White”. It can be named after the quality of the solar light by using an artificial light source. The efficiency of the 3030 packaging component can meet the energy efficiency specifications of the American lamp DLC.
