Compared with the traditional LED display, LED projecting a small spacing feature is 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, the user can perform simple calculations Qingdao led display, there is an established formula that best viewing distance = spacing /0.3~0.8 . The smaller the dot pitch, the cost of a small pitch LED display higher led display manufacturers, so the actual purchase, users should consider their own cost, demand, application and other factors. Display working state can use a computer for real-time monitoring of Tianjin led display, including temperature, humidity, voltage, smoke, cooling fan operating status and so on. It can occur for a variety of conditions for automatic adjustment process, and provide the location of the abnormal alarm. For example: When a box because of environmental or other factors cause the internal cabinet temperature is relatively high, so in the absence of timely treatment, the power supply inside the box waiting to happen over-temperature protection. If the display working condition monitoring in this case, the system will lower the internal temperature of the display screen through smart regulation working condition. When smart regulation can not lower the temperature to the set target, the system will alarm setting mode by the staff, and provide exception cabinet position, notify the staff timely manner. Ensure the normal operation of the display. Full color led display, Gao Jin photovoltaic (online consultation), Shanxi led display provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin.
