  • Publication number: 20220102605
    Abstract: The present disclosure relates to a display panel and a method for manufacturing the same. The method includes the following. A first adhesive layer and a second adhesive layer are disposed sequentially on a surface of a driving substrate, and the first adhesive layer includes conductive particles. Multiple light emitting units arranged in an array are adhered to one side of the second adhesive layer away from the driving substrate. The second adhesive layer is semi-cured. The first adhesive layer and the second adhesive layer are cured, and the multiple light emitting units are electrically connected with the driving substrate through the conductive particles.

  • Publication number: 20220007525
    Abstract: An adjusting mechanism for tile display screens and a tiled display device are provided. The adjusting mechanism for tile display screens is configured to adjust a gap between two adjacent tile display screens, and includes first support plates, a second support plate, and adjusting fixtures. The first support plates are used to fix the tile display screens in one to one correspondence and are movably connected to the second support plate. Each adjusting fixture is operable to be connected between two adjacent first support plates and includes two adjusting members in threaded connection. A threaded connection length between the two adjusting members is adjustable so that the gap between at least two tile display screens is adjusted.
