At home and abroad most large LED display system essentially consists of several LED panels and LED units connected in series in order plates. LED LED control panel and LED display unit plate main body led unit board, wherein Jiangxi led unit board, LED unit board includes an enhanced signal drive capability BUFFER circuit that generates a dynamic display scan timing of the decoding circuit, a plurality of switches tube and a plurality of LED driving circuits. The communication process: communication signals emitted by LED control panel in series sequentially through each LED unit board BUFFER circuit driven enhancements; each LED unit BUFFER circuit board via the enhanced scan signal (SCANO) available to the LED unit? Yantai decoding circuit board led unit board, decoding circuit decoding generate dynamic display scan timing control switch; enable signal enhancement circuit after BUFFER (ENO) through each LED unit board, the latch signal (LATO), clock signal (CLKO) are supplied to all of the LED unit board LED driver circuit. LED display system, the communication signal only after the data included in each LED module board communication circuit are sequentially connected in series LED, then the LED driving circuit of the LED board unit by a communication data output terminal LED control circuit, the display refresh rate only limited by the transmission speed and the number of LED module board LED communication circuit, so that the communication speed of the order of magnitude of the increase, in most applications the output LED control panel just a set of communication signals, LED display system can be realized control, the LED display system has low production costs, ease of application support. Mainly for display advertising fonts (acrylic, plastic) night effects and identified it as a medium of text or logo, mounted on top of buildings or walls, both during the day and the effect of the performance of identity, but also use LED as light source at night showed another effect, which together with LED lighting applications, control systems led unit board repair, text or logo on the dynamic video control, and in some places thicker atmosphere entertainment, LED light source module has become a corporate showcase Choose one of the most important self-image. Xiamen led unit board, high Jinliang photovoltaic (certified), led unit board provided by the Jinan High Jinliang Optoelectronics Technology Co., Ltd ..
