Most external LED advertising screens on curtain walls use opaque black traditional LED screens, which require independent structures for installation, disrupting the original style of the curtain wall and affecting indoor lighting and visibility. Transparent LED screens have characteristics such as lightweight, transparent, and high brightness, which do not affect the load-bearing and lighting of the curtain wall. Transparent LED screens can be customized according to the shape of the curtain wall, perfectly fitting various curtain walls. Upgrading ordinary glass curtain walls to multimedia curtain walls not only showcases the technological sense of the curtain wall, but also enhances the visual experience of advertising. Its application enhances the commercial value of glass curtain walls and helps commercial centers create urban landmark buildings.
