Huacan Optoelectronics can purchase a large amount of space for lighting chips
Shenyin Wanguo expects the winning rate of Huacan Optoelectronics Online to be 0.93%, and the expected online purchase yield is 0.06%.
According to the survey of the High-tech LED Industry Research Institute (GLII), the high-brightness blue and green LED chips produced by the company can be widely used in mid-to-high-end applications such as full-color display, backlight and lighting after downstream packaging. In 2011, it ranked second in the domestic LED chip market, and the display LED chip market ranked first.
In 2008, Huacan Optoelectronics LED chip was successfully mass-produced. In the early stage of mass production, the company was small in scale, and the products were mainly aimed at the display market with fast growth and strong profitability. In the three years of 2009-11, the company's revenue growth rate reached 117.71%, and the net profit compound growth rate reached 190.80%. In 2011, Huacan Optoelectronics achieved revenue of 474 million yuan, becoming the first LED chip manufacturer and the second largest LED chip manufacturer in China.
2009-2011 Huacan Optoelectronics Business Income Trends (Unit: 100 million yuan)
In 2011, Huacan Optoelectronics successfully entered the lighting chip market by utilizing the technical advantages (consistency, stability, and good color rendering index) in the field of blue-green chips for display. The lighting efficiency of its lighting chip products has exceeded 130lm/W, reaching the international leading level. Therefore, in addition to the display field, Huacan Optoelectronics is expected to benefit from the high-growth lighting field.
GLII expects that in the next few years, Huacan Optoelectronics will gradually occupy the mainstream position in the high-end market, and will open a larger distance with domestic counterparts, and the advantages will be more prominent. With the listing of the leading company Huacan Optoelectronics, the market pattern of LED chips for domestic display screens will be reorganized in the next few years.
Liu Wei, vice chairman and president of the company, said on the first road show on May 21 that in order to promote the improvement of the penetration rate of LED terminal products and the expansion of the application range, the price reduction of downstream LED packaging and application products will lead to the decline of the price of upstream LED chips. .
Liu Wei pointed out that the application field of LED products is expanding and the demand is growing rapidly, but at the same time there is a problem that the investment scale of the LED industry is growing too fast.
Liu Wei stressed that with the increasing installed capacity of MOCVD equipment, LED epitaxial wafers and chip production capacity are expected to rise sharply. If the capacity expansion rate is faster than the demand growth rate, the price of LED chips will further decline.
The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.
Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
