Before the full-color LED display, you need to do a lot of preparation work, but also consider the problems that may be encountered during the use period, how to avoid it, then the editor will talk to you.
1. The content of the full-color LED display screen needs to be prepared in advance, such as the size of the LED display unit template, pixel size, and hemming must be calculated. The power consumption of full-color LED display is divided into average power consumption and larger power consumption. The average power consumption, also known as working power, is the actual actual power consumption. The larger power consumption is the power consumption during abnormal conditions such as startup or full light. The larger power consumption is an element that must be considered for AC power supply. The average power consumption is generally 1/3 of the larger power consumption. The LED display is a large-scale precision electronic device. For stable operation, the AC220V power input terminal or the AC220V power input terminal of the computer connected to it must be grounded.
2. Second, outdoor full-color LED display is often exposed to the sun and rain, and the working environment is poor. When the LED display is wet or severely wet, it will cause a short circuit of the line. In serious cases, it may even cause a fire; the outdoor LED display may be subject犀利士
to lightning Caused by strong electricity and magnetic attacks; the ambient temperature changes greatly. The LED display itself must generate a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may not work properly or even be burned, thereby making the display system unable to work properly; the audience is wide and the line-of-sight requirements are far 3. Wide field of vision; large changes in ambient light, especially direct sunlight.
3. In view of the above special requirements, outdoor LED display screens need to do the following: the screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and it can be smoothly discharged once the accumulated water occurs; Install lightning protection devices on LED display screens and buildings; install ventilation equipment to lower the temperature so that the internal temperature of the screen is between -10℃ and 40℃. An axial fan is installed above and behind the screen body to discharge heat, and how many axial fans are used according to the size of the screen body.
Have you remembered the above three points? With good scientific knowledge in advance, you won’t be ashamed when you encounter problems, and you can solve problems in an orderly manner.
