Description

Technical Field

[0001] The present invention relates to the technical field of billboards, and in particular to a digital media billboard. Background Art

[0002] As a key vehicle for modern marketing, digital billboards are reshaping traditional outdoor advertising with their efficiency, flexibility, and interactivity. Compared to static billboards, their core advantage lies in their dynamic content display capabilities. High-definition LED screens enable multi-screen carousels, real-time information updates, and targeted time-of-day delivery, significantly increasing advertising reach. Digitalization reduces printing consumables and installation costs. Furthermore, the integration of 5G and IoT technologies enables interactive features such as coupon scanning and AR experiences, transforming one-way communication into two-way engagement and significantly strengthening brand-consumer engagement. In the era of information explosion, digital media billboards have become an indispensable smart media node in urban commercial spaces with their technological empowerment, data-driven and green attributes. However, since media billboards are generally installed outdoors, the surface will be covered with dust during long-term use, resulting in a decline in display effect. Cleaners usually need to clean them regularly, but this is more labor-intensive. Therefore, many billboards are equipped with automatic cleaning devices to collect rainwater. However, since rainwater contains dust, these rainwater collection tanks will be clogged and sludge will accumulate too much if they are not cleaned regularly, resulting in turbid water quality and inability to perform normal cleaning effects.
