small touch screen displays.The figure shows one of the OCR coating shapes. Depending on the size of the substrate, the viscosity of the adhesive changes, and the coating shape changes. The goal is to ensure the ductility of the glue while minimizing spillage. In order to prevent glue overflow, a UV glue with a high viscosity is applied on the periphery as a glue frame to prevent glue overflow. To ensure the discharge of gas during bonding, there must be a gap in the coating of the frame glue; at present, some manufacturers have developed AB glue In the process, B glue is applied on the periphery, and OCR (A glue) overflows and quickly solidifies after contacting with B glue to prevent further overflow.
