This is the 2014 annual performance report of the small and medium-sized backlight manufacturer Jufei Optoelectronics (300303.SZ).
On the evening of March 13, Jufei Optoelectronics disclosed the 2014 annual report. According to the report, in 2014, Jufei Optoelectronic Backlight LED realized sales income of 854,470,500 yuan, an increase of 37.04% over the same period of the previous year of 623,369,600 yuan, accounting for the main business income. 86.65%.
Among them, the most intriguing is that Jufei Optoelectronics, which is a small and medium-sized backlight faucet, has begun to exert its strength in the field of medium and large size backlights. According to the annual report data, in 2014, Jufei Optoelectronics made great progress in the middle and large-size backlight field, and its performance has increased substantially. The proportion of its main business income has increased from 21.14% in the previous year to 29.31%. At the same time, dozens of developments have been developed. Medium and large size backlight products of different models and specifications.
"With the accumulation of product development, production management, market development, etc. in the early stage, it has begun to supply large-size backlight devices and light bars to domestic mainstream LCD TV manufacturers such as Skyworth, Hisense and Changhong, as well as several other second-tier manufacturers." Yin Jinghuang, director of Fei Optoelectronics, said that in the large-size backlight field, Korean companies have a certain leading position, and domestic enterprises have entered the stage of rapid market entry. With the enhancement of the strength of large-size backlights in domestic LED packaging companies, domestic enterprises are expected to Welcome more opportunities.
In the LED lighting device business, Jufei Optoelectronics also increased its efforts. In 2014, the company's lighting business realized revenue of 113 million yuan, accounting for 11.43% of the main business income.
However, Jufei Optoelectronics also admits that due to the low gross profit margin of lighting devices, the future growth of the lighting business in total revenue may affect the company's comprehensive gross profit margin. In 2014, the gross profit margin of Jufei Optoelectronics LED backlight business was 30.45%, while the gross profit margin of lighting business was only 16.13%.
In the field of LED flashlights, Jufei Optoelectronics has already sent samples to the application plants in 2014, and mass production can be achieved in the first quarter of this year.
In October 2014, Jufei Optoelectronics announced the “Non-Public Issuance of Stocks Planâ€. The total amount of funds raised is not expected to exceed RMB 600 million. After deducting the issuance expenses, it will be used for “Backlight LED Products (Devices, Light Bars) Expansion Project†And “Lighting LED Product Expansion Project†and “LED Technology R&D Center Expansion Projectâ€.
It is understood that the relevant application materials have been reported to the CSRC and the notice of acceptance issued by the CSRC has been obtained.
When talking about the business growth point of Jufei Optoelectronics in the future, Yin Jinghuang said, “The medium and large-size backlight products are growing rapidly, because the current market share is still small; the internationalization strategy implementation of the small-size backlight business provides new products for the company. Market growth space; the smooth development of new businesses such as optical film and flashlights has fostered new profit growth points for the company."
What is Car Ethernet
Car Ethernet is a new local area network technology that uses Ethernet to connect the electronic unit in the car. Unlike traditional Ethernet, which uses 4 unshielded twisted pair cables, car Ethernet can achieve a transmission rate of 100Mbit/s or even 1Gbit/s on a single pair of unshielded twisted pair cables. At the same time, it also meets the requirements of the automotive industry for high reliability, low electromagnetic radiation, low power consumption, bandwidth allocation, low latency and synchronous real-time. The physical layer of on-board Ethernet uses BroadRReach technology, and BroadR-Reach's physical layer (PHY) technology has been standardized by the One-pair Ethernet Alliance (OPEN). Therefore, it is sometimes called Broad RReach (BRR) or OABR (Open Alliance BroadR-Reach). The MAC layer of vehicle Ethernet adopts the IEEE 802.3 interface standard and seamlessly supports widely used high-level network protocols (such as TCP/IP) without any adaptation.
On-board Ethernet protocol architecture
Vehicle-borne Ethernet and its supported upper-layer protocol architecture are shown in Figure 1. Vehicle-borne Ethernet mainly involves OSI layer 1 and Layer 2 technologies, while vehicle-borne Ethernet also supports AVB, TCP/IP, DOIP, SOME/IP and other protocols or application forms.
On-board Ethernet framework
Among them, AVB is an extension of traditional Ethernet functions, which enhances the real-time performance of traditional Ethernet audio and video transmission by adding precise clock synchronization, bandwidth reservation and other protocols, and is a network audio and video real-time transmission technology with great development potential. SOME/IP (Scalable Service-Oriented MiddlewarE on IP) specifies the video communication interface requirements for vehicle camera applications, which can be applied to the field of vehicle cameras, and realizes the mode control of driver assistance cameras through apis.
As an extension of AVB protocol, Time-Sensitive Networking (TSN) introduces related technologies of time-triggered Ethernet, which can efficiently realize the transmission of automotive control information. In addition, the on-board Ethernet of the 1Gbit communication standard also supports Power Over Ethernet (POE) function and Energy-Efficient Ethernet (EEE) function. The POE function provides power for connected terminal devices while transmitting data through twisted pair cables, eliminating the need to connect external power cables to terminals and reducing the complexity of power supply.
On-board Ethernet standardization
In terms of in-vehicle Ethernet standardization, the IEEE802.3 and IEEE802.1 working groups, AUTOSAR, the OPEN Alliance and the AVnu Alliance have played a major role in promoting it.
The IEEE802.3 local area network standard represents the mainstream Ethernet standard in the industry, and the on-board Ethernet technology is developed on the basis of IEEE802.3, so the IEEE is currently the most important international standardization body for on-board Ethernet. In order to meet the requirements of the car, it involves the development of a number of new specifications and the revision of the original specifications within the two working groups of IEEE802 and 802.1, including PHY specifications, AVB specifications, and single-wire to data line power supply. In addition, AVB related to AV transmission, timing synchronization and other specifications also need to be standardized by other technical committees of IEEE, such as IEEE1722 and IEEE1588.
OPEN Alliance
The OPEN Industry Alliance was launched in November 2011 by Broadcom, NXP, and BMW to promote the application of Ethernet-based technology standards to in-car connectivity. The main standardization goal is to develop a 100Mbit/s BroadR-R physical layer standard and develop OPEN interoperability requirements.
AUTOSAR
AUTOSAR is a consortium of automotive manufacturers, suppliers, and tool developers that aims to develop an open, standardized automotive software architecture, and the AUTOSAR specification already includes the automotive TCP/UDP/IP protocol stack.
AVnu
The AVnu Alliance was formed by Broadcom in collaboration with Cisco, Harman and Intel to promote the IEEE 802.1 AVB standard and the Time Synchronization Network (TSN) standard, establish a certification system, and address important technical and performance issues such as precise timing, real-time synchronization, bandwidth reservation, and traffic shaping.
