Abstract
The invention is applicable to matrix detector or display screens formed by assembling several elementary screens. A matrix screen according to the invention comprises several elementary screens (E1 to E4) spliced together on one of their edges (10, 11). According to the invention, each elementary screen (E1 to E4) includes a mechanical stop device (B1 to B4) which mates with a mechanical stop device on an elementary screen to which it is spliced so that the two elementary screens are positioned relative to each other. This arrangement avoids long and difficult alignment and indexing during the assembly of the elementary screens (E1 to E4) since these operations are completed when the elementary screens are cut, this operation itself requiring the use of accurate alignment and indexing tools.
