Abstract: A manufacturing method of a display panel and a spliced display panel are provided, wherein the manufacturing method of a display panel includes the following steps: at least forming a silver nanowire layer on a lateral end surface of a substrate to be processed. An ultraviolet laser is used to sinter the silver nanowire layer. The silver nanowire layer is patterned to form multiple connection wires connected between the first connection terminal and the corresponding second connection terminal. The configuration prevents insufficiently tight or poor contact between silver nanowires.

Abstract: The present application provides a prism sheet and a display module. The prism sheet includes a base layer and a plurality of prisms arranged on the base layer. The prism sheet is divided into a middle region and edge regions. By making the vertex angles of the portions of the prisms in the middle region smaller than the vertex angles in the edge regions, it may be possible to improve the brightness of the backlight module in the display module and optimize the horizontal viewing angle of the display module.
