Process - Lamination -
In the production of touch screens (TP, on-cell, OGS) and panels (LCD, organic EL panel; OLED), there is a process to paste a film on the panel surface.
The "Lamination" process is the key for securing quality as it is the last step, where accuracy without causing stress to the film is required.
Pasting by roller system
Film separation process
Laminating by the roller system in the non-vacuum (atmospheric pressure) environment.
During the lamination, as we are managing the gap, speed and pressure by numerical control with the right settings, it does not give stress to the film.
Laminating by drum transfer system under non-vacuum environment.
The thin film is fully transcribed to the drum surface under environment of normal pressure (atmospheric pressure), and laminated from the front end.
During the lamination, as we are managing the gap, speed and pressure by numerical control with the best settings, it does not give stress to the film.
Automatic separation by the film separator.
It has been difficult to separate by machine when the adhesive layer and the edge of films were pressed hard together by the cutter and attached firmly. We have realized the automatic peel-able process for the separator, which prevents foreign matters contamination by human intervention.
・Drum transfer system does not support automatic separator peeling.
・There are products in a certain equipment grades that do not support automatic separator peeling.
