A lamination system may be provided for attaching a rigid structure to a compliant structure. The system may include a fixed stage for holding the rigid structure and a movable stage for holding the compliant structure. The rigid structure may be a rigid substrate or an assembly of substrates such as a sensor-on-cover-glass assembly for a touch-sensitive electronic device display. The compliant structure may be a sheet of optically clear adhesive. The system may include a temperature-controlled lamination roller attached to the movable stage. The roller may be heated or cooled during lamination operations. The compliant structure may be laminated onto the rigid structure by pressing the compliant structure onto the rigid structure using the roller while controlling the temperature of the roller. The roller may be heated while pressing the compliant structure onto the rigid structure to minimize the risk of lamination defects.
A lamination system for laminating a hard substrate to a soft substrate, the system comprising:
A method of laminating a compliant structure to a rigid structure using a soft-to-hard lamination system having a first stage, a second stage, and a temperature-controlled lamination roller attached to an edge of the second stage, the method comprising:
A method of using a laminating system to attach a liquid crystal display cell to an assembly that includes a glass layer and a touch-sensor substrate attached to the glass layer, the method comprising:
