Bus is the mainstream of urban travel, while the bus LED display is also the carrier of information dissemination. Then how should we maintain the bus LED display?
1, the power supply is required to be stable, and the ground protection is good. Do not use it under adverse natural conditions, especially in severe lightning weather.
2, do not play for a long time in bright screen, so as not to cause excessive current, the power cord heating too large, LED lamp damage, affecting the screen life. Do not disassemble and splice the screen body at will!
3, LED display, large screen surface can be cleaned by alcohol, or use a brush and dust collector for dust removal, not directly wipe with a damp cloth.
