When it comes to the rainproofness of semi-outdoor LED screens, they are actually better than regular indoor screens, but not as rugged as fully outdoor screens.

We typically measure this by their protection rating, with numbers like IP54 and IP65 being common.

Simply put, the higher the number, the more resistant the screen is to dust and water: IP54 is splashproof and generally handles light rain or showers.

IP65 can handle heavier rainfall, allowing the screen to remain operational even in a downpour.

Semi-outdoor screens also feature a number of rainproof features in their design. The screen’s housing is typically equipped with sealing strips to prevent water droplets from seeping in through gaps.

Drain holes are also provided at the bottom to allow rainwater to drain smoothly and prevent it from accumulating inside the screen.

The modules and circuit boards are coated with waterproof adhesive, forming a protective barrier that prevents moisture from damaging the electronic components.

A real-life example is more illustrative: Imagine you’re walking past a shopping mall after work, and the LED screen in the window is playing the latest promotional ads.

Outside, a light rain is falling, and the raindrops are dripping on the glass, but the screen remains clear and smooth, unaffected by the slightest drop of water.

Or, perhaps you’re waiting for your bus at a bus stop and a sudden light shower breaks.

The LED advertising screen inside the booth continues to display bus information and promotional posters, ensuring that passengers can see them at a glance, unaffected by the weather.

Of course, if a storm or multiple days of heavy rain occur, a semi-outdoor LED screen won’t be as reliable as a fully protected outdoor screen.

In such cases, it’s best to take additional protective measures, such as temporarily shielding or shutting down the screen. This ensures the screen’s safety and prolongs its lifespan.
