1. Control system cost: the display sending card and receiving card fees are generally used Shenzhen Linsn synchronous control system. The main display area size is determined according to the number of cards, in general, the larger the area the higher the density, the more the number of receivers used cards Guangzhou led unit board, our company accounted for separately. 2. The cost of equipment: computers, air conditioners, audio amplifier, power distribution equipment, multi-function control card, surge arresters, and LED video processor, site wiring. (Of course, some of the equipment which the user can also bring their own good Chengdu led unit board, certainly less than the device may not be equipped with Jiangxi led unit board, our company will recommend reasonable configuration.) LED lighting products need to use volume small, less components, long life driving scheme common LED driver circuit architecture can score many categories, such as with a current-limiting resistor circuit architecture, or use switching power supply design circuit architecture, or use linear current-driven LED driver circuit architecture. But limiting circuit architecture is through the resistance line of the series resistance led unit board, LED light source device for controlling the flow of forward current amount, but there are a lot of disadvantages of this design approach has gradually switched linear constant current drive architecture LED light source were driven design. Guangzhou led unit board, led unit board, 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!
