Description

Technical Field

[0001] The utility model relates to the technical field of insulating films, in particular to a multi-in-one composite insulating film with reduced defect rate. Background Art

[0002] In recent years, the manufacturing cost pressure of manufacturing liquid crystal display modules and AMOLED display modules has been increasing. In order to reduce material and labor costs, when multiple single-sided adhesive insulating films for device areas (hereinafter referred to as insulating films) need to be attached to liquid crystal display modules and AMOLED display modules, the insulating films adopt a multi-in-one composite structural design. This structure requires adding a single-sided weakly adhesive PET transfer film (hereinafter referred to as transfer film) as the carrier for multi-in-one. However, in the actual attachment process, affected by factors such as the small size and poor flatness of the device area, reverse release defects such as the insulating film being lifted when the transfer film is peeled off after attachment are likely to occur.
