Since the mass production on September 27, 2011, BOE Beijing's 8.5th-generation line has achieved a product yield of more than 90% in just over two months, and the highest single-day yield rate has reached 94%, ranking it at the international advanced level.
BOE Beijing's successful production of the 8.5-generation line made BOE the only high-tech enterprise in mainland China that can provide a full range of LCD screens from 1.8 inches to 55 inches, and led the flat panel display industry in mainland China into the era of full localization of LCD screens. Currently, BOE's 8.5-generation LCD screen has been applied to well-known brand TVs such as Konka, and has achieved unanimous praise from customers and consumers.
It is understood that the Huaxing 8.5-generation project has been in production since October 2011. During the operation, all work has progressed smoothly. The capacity and yield rate have been climbing. The monthly investment in glass substrates exceeds 30K, and the product yield rate rises rapidly. The overall product yield has exceeded 86.0%. Huaxing Optoelectronics stated that the company will accelerate its progress in accordance with established plans. In 2012, it plans to import 37-inch, 46-inch, 48-inch, 55-inch and other specifications.
Static var generator cabinet takes DSP as the core, connects the self-changing bridge circuit in parallel with the power grid through the reactor, adopts the real-time data acquisition technology and dynamic tracking technology to detect the grid voltage and current information, and calculates the grid voltage and current through the internal DSP calculation. After that, the reactive power component of the load current is extracted, and then the PWM signal is driven to drive the IGBT, and the three-level topology circuit is controlled according to the reactive current to generate a reactive current that meets the requirements, so as to achieve the purpose of reactive power compensation.
