What is the status of the advanced packaging industry 2023?

The semi-annual “transcripts” of 11 LED packaging listed companies revealed their clues. Only 3 companies including Mulinsen, Zhaochi, and Queendom achieved double profits, while 3 companies including Wanrun Technology, Ruifeng Optoelectronics, and Changfang Group did not. Net profit was negative.

Especially in the first quarter of this year, it has been evaluated by many LED industry professionals as the “darkest” Q1 ever. There are very few LED packaging listed companies that can achieve double growth in profits.

Since entering the second quarter, the LED industry has gradually recovered and the market demand for LED applications has recovered significantly. In the first half of this year, a number of listed LED lighting and LED display companies achieved good results against the trend.

Where is the “miserable” LED package?

Under the influence of domestic and foreign macro factors, the rapid growth of the global economy has encountered obstacles, and the balance of supply and demand of products in various industries around the world has undergone certain changes. Coupled with the domestic economy turning to high-quality development, all industries are facing certain pressures and challenges in the short term.

Among them, the pressure on the LED packaging industry is particularly obvious. Especially on the backlight and display side, although the downstream demand keeps growing, due to the sluggish demand last year and the backlog of inventory, the transmission to the midstream and upstream is relatively slow, and the recovery speed is not as fast as expected.

As the largest LED packaging manufacturer in China, Mulinsen achieved a 10.55% growth in its “LEDVANCE” brand in the first half of this year, but its “Mulinsen” brand revenue was only 2.867 billion yuan, a year-on-year decline of 9.6%.

Affected by the shrinking consumer demand in the market, Hongli Zhihui’s LED semiconductor packaging business revenue in the first half of this year was 1.336 billion yuan, a 7.23% decline from last year. To this end, Hongli Zhihui will continue to consolidate the strategic foundation of the LED semiconductor packaging business, leverage the Mini LED project to achieve a breakthrough in the sector, and comprehensively enhance its competitiveness and influence in the LED segment.

In the face of fierce market competition, Wanrun Technology’s net profit continued to suffer losses, but the loss range narrowed by 83.85% year-on-year. Similarly, Refond Optoelectronics’ display LED business and lighting LED business sales have both declined, and net profit has also turned from profit to loss.

At the end of December 2022, after Changfang Group’s light source packaging business moved to Nanchang, it was basically in the state of commissioning and trial production in the first half of this year, which affected order delivery and led to a decline in revenue. In addition, after the comprehensive strengthening of Kang Mingsheng’s management and control on August 8, 2022, production and operation were disrupted by the obstruction of Kang Mingsheng’s original management team. In the first half of 2023, customers and suppliers are still in the recovery period, and production orders and material supply are affected to a certain extent. It also leads to a drop in income.

Where is the “outlet” for LED packaging?

Against the backdrop of a downturn in the general environment, how to develop with high quality has returned to the most important issue for enterprises at present.

In the past two years, the packaging capacity of traditional lighting LED devices with a large area and wide range has been overcapacity, and the packaging production capacity has been concentrated to leading manufacturers, which shows that the market concentration in the LED packaging field will further increase.

At the same time, leaders in the packaging industry have deployed niche markets one after another, and Queendom has strengthened its channel layout and continued to cultivate and develop around future market growth points such as Mini/Micro-LED new displays, smart lighting, outdoor lighting, and automotive lighting.

In the field of automotive LED, with the emergence of new technologies such as smart cockpits, the development of intelligence and multi-function is widely favored by consumers, and the penetration rate has increased. The healthy competition of car manufacturers has spawned AR-HUD, smart car lights, and digital headlights. , car display, car ambient light and many other car LED application scenarios.

In the field of Mini/Micro LED, the application scenarios of Mini LED continue to expand, the commercialization process is accelerated, and consumer-side application products continue to emerge. Application terminals cover TVs, monitors, car screens, commercial display screens, medical screens, notebooks, etc. Queendom Micro LED has also successfully cut into the display of AR devices by virtue of its advantages in brightness and reliability.

Especially in the field of vehicle display, the broad market prospect has attracted many LED packaging manufacturers such as Queendom, Dongshan Precision, Nationstar Optoelectronics, Hongli Zhihui, Jinko Electronics, Jingtai, Jufei Optoelectronics, Refond Optoelectronics, etc. , and achieved remarkable results.

It is understood that Nationstar Optoelectronics’ in-vehicle Mini LED backlight display is carrying out sample certification with customers; Jinko Electronics has launched a variety of car-grade LED devices and modules; The third-generation SAIC Roewe RX5 and other cars; Queendom’s Mini LED products and technical solutions have also cooperated with many customers for verification.

In addition, in the field of high-end lighting such as plant lighting and health lighting, LED packaging manufacturers such as Queendom, Nationstar Optoelectronics, Hongli Zhihui, and Xuyu Optoelectronics have also achieved good results.

“Price rising tide” ushered in an inflection point

Since May, LED packaging manufacturers have sent out price hike signals one after another, and the LED packaging industry has finally ushered in a dawn.

Queendom LED has noticed that many packaging manufacturers including Dongshan Precision, Mulinsen, Ruisheng Optoelectronics, and Zhaochi Guangyuan have successively adjusted prices since May, and some manufacturers even raised prices twice in just over a month. The price increase is basically around 10%.

In the few days since September, Mulinsen, Dongshan Precision, Ruisheng Optoelectronics, Shanxi Xingxin Semiconductor and other companies have issued price adjustment notices again. The current round of price increases ranges from 5-15%, and the coverage of price adjustment products has also expanded. .

Indeed, the improvement in inventory and the urgency to make profits after the continuous price war have supported the price increases of RGB packaging companies and LED display manufacturers.

And rounds of price increases have also pushed the LED industry to usher in an inflection point. At present, the inventory of the entire industry chain is returning to the normal “water level” or even lower than its average level, and some enterprises have begun to replenish inventory. Especially on the LED packaging side, some production lines that were shut down at the end of last year and early this year began to resume operation.

It is worth noting that the current price increase of RGB packaging is also based on the production reduction since last year, and even after multiple price adjustments, the current price is still far from that in 2021.

“The production capacity that was reduced last year has not yet been reopened.” A salesperson from a major RGB packaging factory told Gaogong LED that the current market situation can only be said to have barely returned to a relatively normal level.

GGII analysis believes that in order to truly resolve overcapacity, the first step is to speed up the application of downstream display applications in various market segments; at the same time, packaging companies must also strengthen self-discipline, actively control the pace of production, and make up their minds to truly reduce production. Products must resolutely reduce production.

In general, in the future, with the increasing volume of the Mini/Micro LED market and the significant growth of high-end segment markets such as automotive LED, plant lighting, and health lighting, it is expected to drive a steady increase in the output value of LED packaging.

Significance of LED agricultural lighting

In a large agricultural country, with the development of agricultural technology, the problems faced by agricultural development are also increasing, such as the increasing impact of climate change on agricultural production, etc. Modern agriculture with high technology, low consumption and high efficiency has become an important direction of agricultural development ;

It has an important strategic position in China’s agricultural development and is highly valued. In 2020, China’s State Council No. 1 Document “Several Opinions of the Central Committee of the Communist Party of China and the State Council on Intensifying the Overall Planning of Urban and Rural Development and Further Consolidating the Foundation for Agricultural and Rural Development” also clearly stated that it is necessary to actively support the transformation of agricultural development methods and improve agricultural technology innovation and promotion capabilities.

It should be noted that with the continuous development of modern agriculture, the demand and energy consumption of agricultural lighting are constantly expanding, which also poses new challenges to traditional agricultural lighting technology. As a new generation of light source, LED, in addition to the characteristics of environmental protection and energy saving, compared with artificial light sources such as fluorescent lamps or high-pressure sodium lamps commonly used in traditional agricultural fields, has the characteristics of adjustable light quantity, adjustable light quality, low cooling load, and allows increased cultivation per unit area. It is a very suitable artificial light source for closed and environment-controlled agricultural production environments, such as plant tissue culture rooms. At the same time, it also has great application value in farming and microalgae cultivation.

It is foreseeable that the application of LED will bring more innovations to agriculture. For example, the plant factory is considered to be the development stage of facility agriculture, integrating modern biotechnology, information technology, artificial environment control and other high technologies. Not only the output is higher than Open field cultivation is multiple times, and it can also be produced on non-arable lands such as Gobi, deserts, islands, water surfaces, and even urban buildings. It is also considered to be an effective technical means to solve problems such as population, resources, and environment in the future.

Whether it is from the perspective of promoting the development of modern agriculture or realizing energy conservation and environmental protection, the application of LEDs in agriculture is of great significance, and the status and development needs of agriculture also provide development opportunities for LEDs.

LEDs have begun to be used in agricultural lighting, such as the establishment of solar photovoltaic LED plant factories in some domestic agricultural demonstration areas. In addition to some applications, the research and development of related technologies for the application of LEDs in the agricultural field has also attracted increasing attention.

In December 2020, the “Plant Factory Innovation Achievement Conference” was held at the Chinese Academy of Agricultural Sciences. The high-tech enterprises affiliated to the Chinese Academy of Agricultural Sciences launched a family version of the plant factory and a series of home gardening products, and signed strategic cooperation agreements with dozens of internationally renowned companies. , reached an agreement on technological innovation and market development in the fields of LED plant lighting source, industrial control, air conditioning environment control, nutrient solution preparation, etc., and signed a strategic alliance.

The holding of the press conference not only marks the official birth of the first home-based plant factory in China, but also heralds the formal formation of a strategic alliance for the research and development of the plant factory.

In addition, with the development of LED technology, the United States, Japan, South Korea and other countries have taken the application of LED agricultural lighting as an important development direction and actively deployed it. Many manufacturers at home and abroad have also entered into agricultural lighting, and the competition of LED in the field of agricultural lighting is quietly going on.

Traditional lighting is a visual application. It is a lighting system (lighting device) composed of artificial light or natural light that transmits light with specific luminosity and chromaticity requirements to the target object according to the distribution characteristics of scientific design for human perception and information acquisition.

Agricultural lighting is a lighting application method that includes visual and non-visual functions. Traditional agricultural lighting refers to the use of photoelectric light sources to artificially create a suitable light environment or make up for the lack of natural light to regulate the growth and development of agricultural organisms in accordance with the production target requirements of various fields of agricultural production. and an agronomic measure for reproduction.

The emergence of LEDs has pushed agricultural lighting into a new stage of development, called agricultural semiconductor lighting, a new lighting method that belongs to the category of modern agricultural lighting. Agricultural semiconductor lighting refers to the use of semiconductor electric light source and its intelligent control equipment to artificially create a suitable light environment or make up for the lack of natural light according to the law of light environment demand of agricultural organisms and the production target requirements of various fields of agricultural production, and to regulate the life of agricultural organisms. An agronomic measure to achieve high-quality, high-yield, high-efficiency, and stable production goals through growth, development, and reproduction.

Features of agricultural semiconductor lighting:

(1) The electric light source of agricultural semiconductor lighting is the fourth generation semiconductor solid-state light source-light-emitting diode and other modern electric light sources;

(2) The spectrum of the electric light source can be adjusted, and the light intensity, light quality and photoperiod can be controlled in real time;

(3) It can meet the needs of light environment regulation in various fields of modern agricultural production, and achieve the goals of high yield, high efficiency, high quality, and stable yield;

(4) Agricultural semiconductor lighting includes both visual lighting and non-visual lighting. Among them, the lighting of plants and edible fungi belongs to the former, and the lighting of livestock and poultry farming belongs to the visual category;

(5) Agricultural semiconductor lighting can completely break through the diurnal and interannual photoperiod laws of natural lighting, and completely control lighting conditions according to needs;

(6) The control of light environment needs to be carried out in coordination with the control of other environmental elements, and comprehensive and coordinated control. Facility horticulture semiconductor lighting is an emerging research branch of facility horticulture engineering, an important part of agricultural semiconductor lighting, and an important field of non-visual application of semiconductor lighting.
