AI summary

The invention relates to a device and a method for displaying symbols on a matrix screen. Said device comprises means for storing (11) a plurality of static zones (2, 3) of the screen (1) and a plurality of symbols (4, 5) to be displayed in each zone (2, 3), a zone table (12) defining the symbol (4, 5) to be displayed for each zone (2, 3), and means (10) for controlling the display of each point of the matrix according to the symbol (4, 5) retained in the zone table (12) and of the allocation of each point to a given zone (2, 3) determined by the storage means (11). According to the method, in each point of the screen: the zone (2, 3) to which the point belongs is determined by the storage means (11), the symbol (4, 5) to be displayed is determined by the zone table (12), and the display of the point is generated.
