What protective measures should be taken for outdoor digital signage?


At present, Outdoor digital signage is also a new favorite of outdoor advertising media. It can be widely used in finance, taxation, industry and commerce, post and telecommunications, sports, advertising, factories and mining enterprises, transportation, education system, stations, docks, airports, shopping malls, hospitals, hotels, banks and other public places. If we want to use the Outdoor digital signage well, what aspects should we pay attention to? It mainly focuses on lightning protection, waterproof, dust-proof and moisture-proof, circuit chip selection, internal ventilation, and selection of high light wick.

1. Building lightning protection. In order to prevent the electronic display screen from strong electromagnetic attack caused by lightning, its screen body and outer packaging protective layer must be grounded, and the resistance of the grounding line should be less than 3 ohms, so that the current caused by lightning can be drained from the ground wire in time.

2. Waterproof, dust-proof and moisture-proof treatment of the integral screen. The connection between the box and the box and the connection between the screen body and the stressed installation object shall be seamless to avoid water leakage and moisture. Good drainage and ventilation measures shall be taken inside the screen, and if there is water accumulation inside, it can be timely treated.

3. Selection of circuit chips. When selecting a circuit chip, you must select an industrial grade chip with a working temperature of minus 40 ℃, which means 80 ℃, to avoid the failure of the display screen to start due to low temperature.

4. Keep ventilation inside the screen. When the screen is powered on for operation, it will generate a certain amount of heat. If these heat cannot be discharged, when it accumulates to a certain extent, the internal environment temperature will be too high, which will affect the operation of the integrated circuit.

5. Select LED lamps with high luminous intensity to enhance the contrast with the surrounding environment, so that the audience of the picture will be wider, and there will still be good performance in the places with long distance and wide angle of view.
