Display Window Separation Using Thermal Adhesive Softening

The patent applies thermal energy to change the physical state of the adhesive layer from solid to softened state, reducing its bonding strength. This parameter change allows the window to be separated from the display panel without damaging the color layer, as the adhesive becomes pliable and can be cleanly removed rather than tearing the color layer during separation.

The patent performs preliminary heating of the adhesive layer before the separation action. By pre-softening the adhesive through heat application, the subsequent separation process becomes gentle and controlled, preventing damage to the color layer. This preliminary action prepares the adhesive in advance to facilitate damage-free separation.

The heating unit serves multiple functions: it softens the adhesive layer for clean separation, and can also be used to remove moisture or contaminants from the surfaces before separation. This multi-functionality consolidates multiple preparatory steps into one device, reducing overall process time despite the added heating step.

The patent replaces forceful mechanical separation methods with thermal softening followed by gentle separation. Instead of using sharp tools or excessive force that could damage the color layer, the mechanical action is substituted with thermal energy application, making the separation process both gentler and more controlled, thereby protecting the color layer while maintaining efficiency.
