Since its establishment, the company has been engaged in the research, development, production and sales of LED epitaxial wafers and chips. The main products are GaN-based high-brightness blue and green LED chips.
According to the prospectus, the proportion of the total output of the blue epitaxial wafers produced by Huacan Optoelectronics in 2011 has risen to 96.73%, which is basically self-produced. The company will mainly use the epitaxial wafer production capacity to produce blue epitaxial wafers. Beginning in the fourth quarter of 2011, with the increase in the number of MOCVD equipment, the company has achieved full production of green epitaxial wafers.
Huacan Optoelectronics achieved operating income of 474 million yuan in 2011, net profit attributable to ordinary shareholders of the company was 125 million yuan, and the company's sales revenue increased from 100 million yuan in 2009 to 474 million yuan in 2011; the compound annual growth rate reached 117.36%, higher than the market's growth average.
According to the prospectus, Huacan Optoelectronics will mainly build the third phase LED epitaxial chip construction project (as shown in the following table). The third phase of the project aims to expand the production of the original base. The products produced by the project are consistent with the existing products. They are high-brightness blue and green LED chips, which can be used in display, backlight and lighting applications.
Huacan Optoelectronics raised funds investment project
The project is planned to build a LED blue-green light epitaxy and chip production base with a construction area of ​​approximately 48,460 square meters in the East Lake Development Zone of Wuhan. It is planned to complete the infrastructure construction, equipment installation and officially put into operation within 2.5 years. After the third phase of the project is completed, it will add a total of 1,831 KK/month for the company's new blue and green light chips, equivalent to 104,400 pieces/month for the 2-inch epitaxial wafer.
The investment plan for the raised funds of Huacan Optoelectronics Phase III LED epitaxial chip construction project is as follows:
What is Industrial DTU? Industrial DTU characteristics and application field analysis
What is DTU?
A Data Transfer unit (DTU) is a wireless terminal device that converts serial port data into IP data or IP data into serial port data over a wireless communication network.
