According to the LEDinside research center (LEDinside), the LED industry was affected by poor terminal demand in 2018, and the impact of Sino-US trade friction caused the client to reduce the inventory level, and the demand for the year was frozen.
Looking forward to 2019, although the overall industry still has the risk of oversupply, the special application prospects including small-pitch led display, Mini LED backlight, UV-C LED, automotive lighting and high-efficiency LED lighting are promising, which is expected to drive demand for temperature increase.
It is pointed out that after the G20, Sino-US trade frictions temporarily ceased, and the tariffs originally scheduled to be imposed on January 1, 2019 will be suspended for three months. For the LED industry, the future may face a 25% or 10% tariff difference, which will change the manufacturer's procurement plan and move the factory decision, and then the dynamics of both China and the United States will be unclear, which will delay the original decision-making time, the industry wait-and-see atmosphere and The uncertainty of the market is likely to suppress the performance of the demand side.
Small pitch led display
With the increase in demand for LED display screens in the rental market, retail department stores, conference rooms, etc., the output value of small-pitch led displays in 2018 has grown by 31% annually. According to LEDinside observation, compared with other applications, the profit of led display is considerable, and the minimization of dot pitch continues to bring more new application scenarios.
In addition, the price of LED chips has fallen, making the price of LED display products surpass other alternative technologies in commercial use. Therefore, many LCD panel manufacturers and commercial display brand manufacturers are eager to develop small-pitch led displays.
It is believed that manufacturers that can achieve certain market share in the field of small-pitch led display supply chain, such as Jingdian, Sanan, Huacan, Yiguang, Guoxing, Hongqi, Jingtai, etc. will benefit, supporting driver IC Vendors such as Accumulation Technology, and the creation of the North will also benefit.
Applied to liquid crystal displays, combined with direct-area area backlight technology, can increase the contrast and brightness of liquid crystal displays, and provide consumers with an alternative to OLED. Take the 27-inch desktop e-sports display with backlight as an example. The LED usage is about 4,000~12,000, and the multi-zone backlight independent control will help improve the contrast and give the player a better visual experience. .
However, at this stage, due to the high technical cost, it can only be applied to high-end models. If the cost of the Mini LED and the huge transfer process can achieve breakthrough development, the Mini LED backlight technology is expected to be widely applied to various displays, which will effectively boost the chip demand of the LED industry.
It is expected that manufacturers who have been deeply involved in the backlight field for a long time, or have backgrounds in panel resources, such as Jingdian, Longda, Guangxu, Rongchuang, Ruifeng, etc., will be the first to reflect the Mini LED backlight business opportunities.
The application market includes three growth kinetics: static water sterilization, surface sterilization and mobile water sterilization.
Static water sterilization and surface sterilization applications (such as air purification, home appliances, etc.) have low requirements on time, but since such applications are introduced into consumer home appliances, the requirements for product cost performance are quite high, resulting in short-term UV-C LEDs. It is not widely available.
As for the application of mobile water sterilization, rapid sterilization is required, and the power requirements of the product are high. Therefore, the UV-C LED power specification must be higher than 40-50 mW.
It is believed that the biggest challenge of UV-C LED at this stage is still that technology and efficiency need to be improved, but such technical obstacles will gradually overcome in the future. However, UV-C LEDs belong to niche markets, and technology needs to accumulate for a long time, so only a few manufacturers such as Seoul Semiconductor, LG Innotek, Qingdao Jiesheng, Guanghao, Yanjing, Lite-On, Yiguang, Violumas, etc. will benefit. .
With the price reduction and functional increase of LEDs, the output value and penetration rate of automotive LED lighting continue to grow. In 2018, the LED output value of automotive LEDs increased by 15% annually. Among them, the demand for headlights and vehicle panels has increased rapidly.
However, due to the high requirements of LED manufacturers in the automotive pre-installation market, and more and more auto manufacturers hope to integrate the sensing components with the lights, the current automotive pre-installation market is still Osram, Nichia, LumiLEDs. Wait a few manufacturers to oligo. The remaining LED manufacturers mainly cut into the after-loading and modification market, or cut into the applications where the thresholds such as interior lights and taillights are relatively low and the LED penetration rate is high.
High-efficiency LED lighting
Due to the increasingly stringent regulations on energy conservation and environmental protection in various countries, LED lighting is gradually pursuing products with higher light efficiency. In addition to the US DLC regulations for lighting products to improve light efficiency year by year, the European Union is also drafting a new energy standard draft (Ecodesign Working Plan 2020), requiring lighting products to have a luminous efficacy of at least 85 lm / W. Although the draft is still in the comment period, it has gradually attracted the attention of LED manufacturers for high-efficiency LEDs.
