LED large screen maintenance is very important

LED large screens are getting closer and closer to our lives. You can see large LED screens everywhere when you walk on the street. So those factors can affect the life of LED large screens. There are many reasons that can cause them. The first is Protective performance, waterproof and moisture-proof is very important. Outdoor LED large screens have very high waterproof requirements. We usually see that after the LED large screen is installed, it will be decorated with aluminum-plastic panels or stainless steel. In the process of edge sealing, often because If you are in a hurry to meet the waterproof requirements, it is recommended that the upper side of the LED large screen must be flattened with wooden boards during the edge sealing process, and then glued to the aluminum-plastic board with glass glue to ensure that the glass glue is completely bonded. Apply glue to the upper gap for reinforcement. Indoor LED large screens have very high requirements for moisture resistance, especially in the period of resurgence in the southern region. We can see water seepage in the stairwell or on the walls. It is conceivable that there will be a lot of water behind the LED large screen, so how? Only in this way can the phenomenon of moisture-proof affect the large led screen. It is recommended that the large screen should be ventilated and should be played regularly. If it does not work for a long time, the circuit board and its components will be corroded by moisture for a long time and parts will appear of aging. In addition to the protection factor, wire is also a very critical factor for LED large screens. The wires used by formal enterprises are pure copper wires, and some LED large screen manufacturers will use aluminum-magnesium wire or copper-clad aluminum inferior wires in order to reduce costs. As a result, the LED large screen will experience wire aging in less than a year. If something goes wrong, workers must be sent to the site to troubleshoot it, and they must also bring newly purchased wires, which will bring wire costs and labor costs to consumers. double spending.

The LED power distribution cabinet is also one of the core components. The LED display screen with an area of ​​more than 10 square meters will basically install a power distribution cabinet to ensure that the 380V voltage and current can be reasonably and evenly distributed to the LED large screen. The working time of the screen is also one of the key factors. We know that the car needs to cool down the engine, gearbox, and sensor driving device after working for a long time. The LED large screen is an electronic product, and it also needs to be cooled and maintained. It is recommended to do it every 4 hours. Closed for 30 minutes, the screen works less than 12 hours a day. Large LED screens are usually composed of a main controller, a scanning board, a display control unit and a large LED screen body. The main controller obtains the brightness data of each color of each pixel on a screen from the computer display card, and then distributes them to several scanning boards. The scanning board is responsible for controlling several rows (columns) on the large LED screen, and the LED display signals on each row (column) are serially transmitted through each display control unit in the row, and each display control unit directly faces the Large LED screen.

Every detail is very important. Only by paying attention to the care of the LED large screen at ordinary times can the ideal lifespan be achieved. .
