Compared with the traditional LED display, bright color led unit board, fine pitch LED prominent feature is a smaller dot pitch. In practice, the smaller the dot pitch, the higher the pixel density, suitable viewing distance is more recent, on the contrary, is suitable farther viewing distance. Small pitch LED display in order to achieve the best visual effect, best line of sight, led unit board offer, users can perform simple calculations, there is an established formula that best viewing distance = spacing /0.3~ 0.8. The smaller the dot pitch, the higher the cost of a small pitch LED display, so the actual purchase, users should consider their own cost, demand, application and other factors. Energy-efficient LED display is using four 200-watt per square meter power, led unit board production, so that the maximum power consumption does not exceed 680 watts per square meter. Since the effective power output is 85% of basic LED display refresh rate information per second is the number displayed in full, in Hz. Refresh rate is too low, the human eye will shake LED display phenomenon, there will be scanning line appears through the camera. Usually the human eye to 300Hz refresh rate requirements for the above, that as long as the refresh rate of more than 300Hz, Hebei, led unit board, most people watch with the naked eye LED display will not be shake the feeling, but if you use the camera to shoot, then different according to different cameras setting general minimum requirement in order to capture less than 600Hz scanning lines. Hebei, led unit board, Gao Jin photoelectric, led unit board quotes provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Hebei, led unit board, Gao Jin photoelectric, led unit board offer is Jinan Gao Jin Optoelectronics Technology Co., Ltd.
