LED display spectrum technology application in various industries

The rapid development of mobile Internet and Internet of Things technology at this stage has led to explosive growth in the construction demand of smart cities. Among them, the smart display integrates functions such as energy-saving display, smart transportation, smart security, smart home, mobile communication, and cultural media, and is the best carrier for smart city construction. It is estimated that the global smart LED display market will reach US$13.427 billion in 2020. The huge market prospect has become a blue ocean for many companies to compete for layout. Especially since 2017, the giants have obviously stepped up their development in the field of smart display.

Now analyze the layout trend of China's LED display industry in 2017. Analysis of the layout trend of China's LED display industry in 2017 Classroom display can prevent myopia Happy mood 2017-2022 China's LED display industry special research and investment value forecast report shows that Zhejiang Kaiyao located in Beilun is the largest LED display in our city As an export manufacturer, the output value in 2016 is expected to reach 1.5 billion yuan, but 90% of it is OEM for foreign brands such as Philips and Osram. The sharp decline in foreign trade export profits has made companies eager to expand the domestic market and create their own brands.

The entry point they chose was the health display, starting with the classroom display. "The function of classroom health display can not only effectively reduce the risk of myopia, but also regulate people's psychological state, and even affect endocrine." Liu Qiang, President of Zhejiang Kaiyao Display Co., Ltd. said, "Scholars in the industry have done experiments, using a The old hen that lays one egg in 24 hours is put into a black box, and the display is turned on for 8 hours and turned off for 8 hours. After a few days, the egg laying cycle of the hen is shortened from 24 hours to 16 hours. Visible light has a huge impact on animals.

"Currently, Kaiyao's classroom health LED display has exceeded the health standard in terms of blue light, strobe, color temperature, brightness and other technical indicators, and participated in the drafting and formulation of the "Energy-saving Certification Technology for Display Products in Primary and Secondary Schools and Kindergarten Classrooms" It is understood that this product has been used in schools such as Xiaoshi Middle School and Ningbo Middle School. "When the display is too white or too bright, it will make people depressed and nervous, while the display light of warm colors will make people sleepy and distracted." unconcentrated.

After repeated experiments, we have kept the display color temperature at 4000K~5000K, which is conducive to efficient and pleasant learning for students. "He said. Light cultivation of Ganoderma lucidum can also prevent pests and diseases. Ningbo Shengpu Optoelectronics Co., Ltd. is aiming at another "black technology"-LED light cultivation of crops.

"In fact, light cultivation has been widely used in seedling cultivation. However, there are several disadvantages in using traditional incandescent displays or sodium displays: one is that the cost is too expensive and it is not easy to promote; the other is that the heat generated by incandescent displays will burn plants; the third is the lifespan of traditional displays Short, poor controllability. Therefore, it is very appropriate to use LED lighting in this link.

"Wang Yuhong, vice president of Ningbo Academy of Agricultural Sciences, said. Yin Hui, deputy general manager of the company, said that their research and development team noticed that "succulent plants" became the new favorite of white-collar workers, and developed a "LED plant growth display". Using the principle of spectroscopy, the succulent plants that have been placed indoors for a long time can fully absorb the red light that promotes photosynthesis in the LED display light, so that the plants can avoid death due to long-term lack of light.

Coincidentally, Ningbo Jinong Technology Co., Ltd. has developed a home planting display with a height of more than 2 meters, which can grow various vegetables and ornamental plants in the case of insufficient indoor light. According to Lou Xinxin, the person in charge of the company, this product was previously developed for border guards stationed in high-altitude, alpine regions and islands, where the weather conditions are harsh and transportation is inconvenient, and soldiers cannot eat vegetables. And this product can cultivate a small amount of vegetables by using the principle of spectrum.

At the forum site, Professor Zhou Weijun, director of Zhejiang University's Institute of Agronomy and Crop Science, also introduced the LED light cultivation he developed. LED display screens have become a new outlet for the layout of Ningbo enterprises. "Scene display screens have become the next target of smart LED display screens. For example, when the mood is bad, the display switches to warm colors; the brightness is automatically reduced when the elderly enter the room; Excitement has increased..." Liu Qiang said, "LEDs, a semiconductor material itself, are electronic components and are very easy to control, so the smart market is huge." When the Internet of Things and sensor technologies gradually mature, smart display screens have become the layout of many enterprises. the next segment of the market.

At home, when the owner wakes up at night, the display light will light up slightly; when returning home, the display in the living room will automatically turn on; when the life of the display bubble is approaching, it will automatically remind you to replace it... The products of Ningbo Enterprise already have these functions. At present, companies such as Sunpu Optoelectronics have cooperated with OEMs such as Chery and Volkswagen to deploy in this field. This year, the output value of Shengpu Optoelectronics' car front display will reach 30 million yuan.

Yin Hui, deputy general manager of the company, predicts that next year the company's business will achieve explosive growth. In recent years, the continuous increase in the number of automobiles has also made Ningbo enterprises begin to work hard to enter this large market. According to Wu Mingming, in the past five years, the market share of automotive LED displays has doubled, and Ningbo's automotive industry has a strong foundation. Local companies should work hard to seize the market.
