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 body system, wherein, LED unit board includes enhanced signal drive capability BUFFER circuit that generates a dynamic display scan timing of the decoding circuit, a plurality of switches 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? decoding circuit board, generating a dynamic decoding circuit decodes the display scan timing control switch; BUFFER circuit enable signal after enhancement (ENO) by each of the LED unit board, the latch signal (LATO), the clock signal (CLKO) The LED units are supplied to all the LED drive circuit board. LED display system, the communication signal only after the data included in each LED unit plate sequentially concatenated communication circuit led display LED, then the LED driving circuit of the LED unit by the data output terminal board LED control the communication circuit, display refresh rate is only limited by the number of communication speed communication circuits and LED LED unit board led display Qingdao, so that the communication speed of the order of magnitude improvement in most applications, LED control panel only output a set of communication signals , can realize the control LED display system, the LED display system has low production costs, ease of application support. In recent years, along with the notification LED electronic display led display quotes conduct, LED electronic screen application areas more widely, by virtue of the LED electronic screen brightness, high refresh rate and other advantages, agility become the leader in the field show screen category Wuhan led display, but it is precisely because of light pollution and high-brightness LED electronic display constituted often been criticized by everyone. In order to prevent light pollution is very good, especially in Jiangsu brightly colored electronic compiled some security for LED electronic display brightness parameter setting methods and security measures. Indoor led display screen _ _led high Jinliang photoelectric provided by Jinan High Jinliang Optoelectronics Technology Limited. Jinan High Jinliang Optoelectronics Technology Co., Ltd. (www.zhkyled.com) strong, credible, in Jinan, Shandong liquid crystal device industry has accumulated a large number of loyal customers.
