Abstract: Device for the dynamic display of information relating to an electronic system of variable configuration and/or composition which uses, on the one hand, an autonomous display module comprising, mounted in a support of small dimensions, a display circuit comprising a display, preferably of the liquid crystal type, driven by a display controller coupled with a status memory and a source of renewable energy connected to the display circuit, and, on the other hand, a means of elaborating, by said system, digital data characterizing it, from both the hardware and software points of view, and a means enabling said data to be transmitted into said status memory, with a view to displaying them on said display. Such a device applies notably to the modular electronics used in aeronautics.
