户外广告牌防雨彩色跑马灯

In fact, the most garbled characters occur on outdoor display screens, especially on the marquee text display at the door lintel, and most of them occur after it rains. This indirectly explains why the LED display screen is garbled. Yes, garbled characters on LED displays are mostly related to water leakage. Due to improper rainproof measures, water infiltrates after raining. This causes a short circuit on the circuit board, resulting in garbled characters. If this happens, Jianyi will immediately find the supplier or maintenance manufacturer for repair. Don't ignore it just because it may be restored later. Recovery is likely to be due to water damage and drying. If this situation is not resolved in time, not only will it cause garbled characters in the future, but long-term water immersion will inevitably cause damage to the circuit board and even leakage, short circuit and fire.
Another situation is the problem of transmitting data. The cause of this problem may be damage to the control system board, damage to the data line interface, damage to the data line, or signal interference. The specific circumstances need to be investigated one by one.
