Patent Images
1. A network of a plurality of display devices (HL, HR, L1, L2, R1, R2, C) comprising a graphic generation unit UGG comprising at least two channels, a screen, electronic means for controlling the screen and graphic data bus inputs and outputs BGG, characterized in that each display device comprises:
- a network of graphic data,a switch (50),a means for detecting a failure and a means for controlling the switch;
the switch directing to the graphic data network, according to the detected failures, the graphic data of the UGG and those originating from the BGG inputs either to the screen or to the BGG outputs, and in that the network of display devices allows a first display device (L1) to be used as a relay and to transmit an image originating from a second display device (C) to a third display device (L2) of the network (FIG. 9).

Abstract
The invention relates to a flat screen device (L2) comprising a multi-channel graphic generation (UGGL2) and a video data switch (50). It also relates to a method for managing a data network making it possible to improve the reliability of a network of several displays by improved management of all the graphic generations. The preferred field of application is that of display devices forming the cockpit of aircraft.
