At home and abroad Most large LED display system consists essentially of LED control panel and a number of LED units connected in series in order plates. LED LED control panel and LED display unit board composed of the main system, which, LED unit board includes enhanced signal drive capability BUFFER circuit which generates a dynamic display scanning timing decoding circuit, a plurality of switches and a plurality of LED driver circuit . The communication process: communication signal LED control panel issued sequentially through each series of LED unit board BUFFER circuit driven enhancement; each LED unit BUFFER circuit board via enhanced scan signal (SCANO) available to the LED unit? board decoding circuit decoding circuit decoding to generate dynamic display scanning timing control switch; enable signal BUFFER circuit the enhanced (ENO) through each LED unit board, the latch signal (LATO), the clock signal (CLKO) are supplied to all of the LED unit board LED driver circuit. LED display system, communication signal only after the data included in each LED unit board LED sequentially concatenated communication circuit, and then the LED drive circuit board of the LED unit by the data output of the communication circuit control LED display refresh rate communication speed is limited only by the number and the communication circuit LED LED unit board of Jiaozuo led module, so that the communication speed of the order of magnitude of improvement in most applications, LED control panel just a set of communication signal output, you can LED display system to achieve control of the LED display system has low production costs, ease of application support. 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 Jinan led module, in general the higher the density of the area is larger reception card number, the more Division I 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, of course, less than the device may not be equipped, our company will recommend reasonable configuration.)
