Abstract: Tiled displays having display tiles having tiles lying in an X-Y plane, the methods and devices being for setting or adjusting the position of neighbouring tiles in a tiled display to reduce differences in the Z direction between tiles of a tiled display, whereby the tiles lie in the X-Y plane.

Abstract: Tiled displays having display tiles, are described as well as methods of making and/or operating tiled displays and tiles. Methods and devices are described for a tiled display having tiles lying in an X-Y plane, the methods and devices being for setting or adjusting the position of neighbouring tiles in a tiled display to reduce differences in the Z direction between tiles of a tiled display, whereby the tiles lie in the X-Y plane.

Abstract: A frame for a display tile made of a first material with a first coefficient of thermal expansion and fastened to a first substrate made of a second material with a second coefficient of thermal expansion. The frame is divided into three parts: a first part to be glued by the adhesive to a lateral side of the substrate, a third part to serve as fastening interface to another structure and a second part to isolate the third part from strain in the first part. Grooves are formed in the second part, the grooves being substantially straight and substantially parallel to the first substrate, the frame having at least one opening made in one of the grooves etched in the metal frame to locally adjust the bending stiffness of the metal frame.
