In current passenger aircraft, signs are used to represent specific information, which reproduce the information as writing or a pictogram. According to one exemplary embodiment of the present invention, an information display system for aircraft is specified, comprising a light source, a projection unit, and a housing. For this purpose, according to one exemplary embodiment of the present invention, the projection unit is implemented in the form of a liquid crystal display, so that, in combination with a high-performance light-emitting diode and a suitable lens, static and dynamic information may be presented on arbitrarily shaped projection surfaces. The flexibility of the onboard information display is thus advantageously increased.
