Abstract: A display screen splicing method and a spliced display screen are provided. According to the display screen splicing method provided in the embodiments of the present disclosure, a first to-be-spliced panel is connected to a second to-be-spliced panel in a splicing area using conductive connecting portions. In addition, the conductive connecting portions are manufactured by inkjet printing to perform connection between the two adjacent to-be-spliced panels by using signals, so as to realize narrow-seam splicing. By means of the display screen splicing method provided in the embodiments of the present disclosure, the process is simplified, and the precision requirements for devices are reduced.

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.
