LED display used in video surveillance and video presentations Jinan led module, the main impetus comes from two things: the first is the LED display with rapid advances in technology, LED rental display of spacing smaller, high density of LED rental display with greater resolution over a limited area, display more clear and delicate. When displaying standard definition image domestically led module, already fully meet the requirements of the resolution. The second is the price factor, once unattainable high density LED die, worth more close to the people. The price per square meter of display area led modules and DLP and LCD products compared to competitive advantages are becoming apparent. It has a very strong competitive potential in surveillance. For the sake of improving the cost structure of LED lighting products, accelerate market wider use, the development of LED lighting applications down through the terminal price vendors have been actively developing the optical / electrical module is highly integrated, integrated design modules! The so-called optical / electrical integration design, that is the LED lighting of LED components, and the driver circuit / protection circuit is provided with a top PCB circuit board, PCB result from the previous amount of at least two (LED module lighting module, LED light source driving module), if the light source and driver module integration, we can reduce a PCB board, the two modules can also be used directly on the PCB copper line connection, and do not need to be assembled through a connector to the line. Domestic _led led module module _ Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd. (www.gjlled.cn) strong, credible, in Jinan, Shandong liquid crystal device industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Gao Jin photoelectric and you hand into the brilliant, for a better future!
