ABSTRACT:
A matrix display device includes an array of display elements each comprising a member (12) rotatable between two states and an array of bearing elements (13) associated with said rotatable members manufactured as a single piece, such as a frame (11).
This allows an improved method of manufacture of such display devices in that a matrix sheet (1) having display apertures (2) and bearing members (3) is produced with spacing such that the frame (11) of display element members (12) aligns with the matrix sheet and the respective bearing elements (13) and members (3) can interengage simultaneously, resulting in saving of time and simplification of the assembly procedure. Once interengaged, the residual parts of the frame (11) are severed and discarded. Matrix sheet (1) is also made as a single piece, enabling a whole matrix of hinged display elements to be made from only two or three parts.
