1、 outdoor LED display screens need to achieve the following: the screen body and the junction between the screen body and the building must be strictly waterproof and leak proof; The screen should have good drainage measures to ensure smooth drainage in case of accumulated water; Install lightning protection devices on LED display screens and buildings; Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ and 40 ℃. Install an axial flow fan above the back of the screen to remove heat. Depending on the size of the screen, how many axial flow fans are used.
2、 Outdoor LED display screens are often exposed to sunlight and rain, and the working environment is harsh. When the LED display screen is wet or severely damp, it can cause a short circuit in the circuit, and in severe cases, it can even lead to the occurrence of a fire; Outdoor LED display screens may be subjected to strong electrical and magnetic attacks caused by lightning; The ambient temperature varies greatly. When the LED display screen is working, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned out, thereby preventing the display system from working properly; Wide audience, long visual distance and wide field of vision required; The ambient light varies greatly, especially when exposed to direct sunlight.
1、 The installation of LED display screen display content requires: 1. The site space should be prepared in advance, such as the size of the LED display screen unit template, pixel size, and edge wrapping must be calculated. The power consumption of LED display screens is divided into average power consumption and maximum power consumption. The average power consumption, also known as working electricity, is the actual electricity consumption in daily life. The maximum power consumption refers to the power consumption during extreme situations such as startup or full lighting. The maximum power consumption is a factor that must be considered for AC power supply, and the average power consumption is generally 1/3 of the maximum power consumption. LED display screens are large precision electronic devices. In order to operate safely and stably, the AC220V power input terminal or the AC220V power input terminal of the computer connected to them must be grounded.
LED display screens should be installed with caution, especially outdoor LED display screens. Waterproof and moisture-proof work must be done well, and if water leaks accidentally, drainage work must be done well! Large outdoor LED display screens must have lightning protection devices, and regular inspections and cleaning should also be carried out in the later stages to ensure the normal operation of LED display screens.
