Display tile with increased display area

A frame for a display tile, the frame comprising:

• a first material with a first coefficient of thermal expansion and being fastened to a first substrate made of a second material with a second coefficient of thermal expansion by means of an adhesive;
• the frame being divided into three parts:
• a first part to be glued by means of the adhesive to a lateral side of the first substrate, a third part to serve as fastening interface to another structure and a second part positioned between the first and third part to isolate the third part from strain in the first part,
• wherein grooves are formed in the second part of the frame, the grooves being substantially straight and substantially parallel to the first substrate,
• wherein the first material of the frame is removed in one of the grooves to reduce the thickness of the first material in the one of the grooves and to perforate the first material in the one of the grooves to locally adjust the bending stiffness of the metal frame.
