Abstract: The manufacturing method for a tiled display includes the following steps. First, an adhesive layer is formed on a substrate. Then, a number of display panels are tiled on the adhesive layer. The bezel regions of the display panels are joined tightly or with a gap in between. These display panels are then assembled into a display module, and the display regions of the display panels jointly form a display region of the display module. Through the adhesive layer and the substrate, multiple display panels are completely attached to the substrate and their bezel regions are joined tightly together or with a gap as a single module. In contrast to the prior art where individual display panel is formed into a module first and the modules are tiled together, the present invention effectively reduces assembly tolerance and prevents reserved gap for thermal expansion being too wide.
