Abstract
A projector of an information display system in vehicles, in particular in aircraft, for projecting images comprising information for passengers and/or crew onto a projection area which is arranged in the vehicle, with the use of a projection lens that images the image contents onto the projection area, which images are generated by a light source and a projection means. An LED array comprising LEDs that can be switched on and off independently of each other is provided as a light source and as a projection means. To generate composite variable image contents the LEDs can be individually selected. Between the LED array and the projection lens a separation box comprising several chambers is arranged. The chambers of the separation box are associated with an LED such that the chambers associated with the switched-on LEDs are imaged on the projection area by the projection lens as parts of the compound image determined by the switched-on LEDs.
