Abstract
A display area drilling and packaging structure includes a back plate assembly, an emitting layer having a drilling area, and a hot melted adhesive layer. The emitting layer is disposed on the back plate assembly, and an annular cutting groove surrounding the drilling is disposed on the emitting layer. The hot melted adhesive layer at least covers an edge of a mouth of the annular cutting groove away from a center. A packaging layer is disposed on the back plate assembly, the hot melted adhesive layer, and the emitting layer.
Claims20
A system, comprising:
- a display area drilling and packaging structure, comprising:
- a back plate assembly;
- an emitting layer disposed on the back plate assembly having a drilling area, an annular cutting groove being disposed on the emitting layer, and the annular cutting groove surrounding the drilling area;
- a hot melted adhesive layer covering at least an edge of a mouth of the annular cutting groove away from a center;
- and
- a packaging layer disposed on the back plate assembly, the hot melted adhesive layer, and the emitting layer.
A display area drilling and packaging method, comprising:
- forming a back plate assembly;
- forming an emitting layer on the back plate assembly, the emitting layer having a drilling area and an annular cutting area surrounding the drilling area;
- forming a hot melted adhesive layer on the emitting layer, the hot melted adhesive layer covering the annular cutting area, a width of the hot melted adhesive layer being greater than a width of the annular cutting area;
- cutting the hot melted adhesive layer and the emitting layer along the annular cutting area to form an annular cutting groove in which the hot melted adhesive layer melts at least covers an edge of a mouth of the annular cutting groove away from the center;
- and
- forming a packaging layer on the back plate assembly, the hot melted adhesive layer, and the emitting layer.
