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 p5 led unit board, 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 number of an LED drive circuit. 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 LED led unit communication circuit board, 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, so that the communication speed of the order of magnitude improvement in most applications, LED control panel just outputs a set of communication signal led unit board p5 can achieve control led unit board p16 LED display system, the LED display system has a low production cost, ease of application support. led unit board wholesalers high gold light more accurate calculation of your audio-visual LED unit board price method: length × height using a cell plate number plate = total number of units using the number of LED unit board such as: 5 meters long and 2 meters high P16 single Use color led display module number: LED display panels use a long number of units = 5 m ÷ 0.256 米 = 19.53125≈20 a high use LED display unit board number = 2 m ÷ 0.128 米 = 15.625≈16 a LED display using the total number of LED unit board = 20 × 16 个 = 320 LED display viewing distance calculation methods: the viewing distance by calculating the LED display, you can help us identify the most appropriate distance from the viewer, and the best viewing angle, led screen to be able to play its unique display. Color mixture distance from RGB color mixing becomes a single color: pixel pitch (mm) × 500/1000 can display a minimum viewing distance from the smoothed image: the pixel pitch (mm) × 1000/1000 optimum viewing distance the viewer can see height from clear picture: the pixel pitch (mm) × 3000/1000 farthest viewing distance: screen height (m) × 30 p5 led unit board, led unit board, high Jinliang photoelectric provided by Jinan High Jinliang Optoelectronics Technology Co., Ltd ..
