More accurate calculation method LED unit board: length × height using cell plate number plate = total number of units using the number of LED unit board such as: 5 meters long, 2 meters high P16 led monochrome display uses several modules: LED display screen long use cell plate number = 5 meters ÷ 0.256 米 = 19.53125≈20 a LED display high-use unit number plate = 2 meters ÷ 0.128 米 = 15.625≈16 a LED display uses the total number of LED unit board = 20 × 16 a = 320 in recent years, LED electronic display along with the notification to carry out, LED electronic screen applications more widely visible LED electronic display manufacturers, by virtue of the LED electronic screen brightness, high refresh rate and other advantages, quickly becomes apparent field screen LED display wholesale category leader, but also 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 Jiangsu brightening electronic compiled some security for LED electronic display brightness parameter setting methods and security approach. Wholesale LED display, LED display, high gold Photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd.
