AI Technical Summary
Technical Problem
The connection of multiple unit panels in splicing displays, particularly those using high-brightness Mini-LED or Micro-LED displays, leads to uneven brightness due to gaps between panels, and conventional adhesive layers cause adhesive seepage during laser cutting.
Method used
An adhesive sheet comprising a first adhesive layer, a second adhesive layer, and a core material between them, with specific tensile properties and gel content, preventing adhesive leakage during laser cutting and ensuring uniform brightness.
Benefits of technology
The adhesive sheet enables effective laser cutting of unit panels, reducing gaps and ensuring uniform brightness in splicing displays, enhancing image quality.

Abstract
The technical problem of the present invention is to provide an adhesive sheet, a unit panel, and a splicing display with good laser cutting processability. This adhesive sheet (1A) is an adhesive sheet (1A) used to manufacture a unit panel (2A) constituting a splicing display. It has a first adhesive layer (12), a second adhesive layer (13), and a core material (14) disposed between the first adhesive layer (12) and the second adhesive layer (13). The elongation at break measured by a tensile test on the adhesive laminate (11) composed of the first adhesive layer (12), the core material (14) and the second adhesive layer (13) at a tensile speed of 200 mm / min is 1000% or less, or the fracture stress measured by the tensile test is 10 MPa or more.
