This article deals with the development of lightweight UHPC facade panel which also can serve as an LED display. Combining both functions into one gives the potential ability to create a LED display on the facade of the building. The article describes the experiences of the development and production of a small-format prototype facade panel, including the installation of LEDs and their electrical connection. The result of the research is the prototype of a 16mm thick small-format lightweight facade panel with a LED display for displaying text on two parallel lines. Thanks to the waffle lightening, the total material and weight savings are approximately 58% compared with the full cross section.
