In a production of touch screens (TP, on-cell, OGS) it is likely that organic substance, such as oil layer, may adhered to surface of the panel, and in a production of panels (LCD, organic EL panel; OLED) cullet (glass particles) may adhere to the panel surface. These contaminations will be causes for air bubbles when laminating a film to the panel, and will lead to lower production yield. With "Polishing" process high level of removing such contamination is required.
In the production of touch screens (TP, on-cell, OGS) and panels (LCD, organic EL panel; OLED), foreign matter (cullet, organic matter) may re-adhere to the panel surface after the surface polishing process.
With "Cleaning" which is a post-processing of polishing, high level of drying performance to remove dust particles from the surface of the panel is required.
With process that controls best lamination position of flexible devices while roller lamination is made along the curved surface, it is managing pressure, speed, and thrust amount. With utilization of a roller, lamination conditions for each of the line (tangential) contact points can be changed. Because a carrier tape is used to hold flexible devices, it can also handle ones with non-rectangular shapes. The non-vacuum lamination makes it easy to accommodate large size materials.
This is a delamination process to peel off carrier glass from a plastic substrate from a carrier glass side, after a film device layer is processed on the plastic substrate. Because the plastic substrate with the processed film device layer is kept basically untouched while carrier glass is being peeled, stress applied to the plastic substrate is minimized.
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 of the process, where accuracy without causing stress to the film is required.
In the production of touch screens (TP, on-cell, OGS) and panels (LCD, organic EL panel; OLED), both bonding cover glass and touch screen, and attaching cover glass and panel are the steps required.
It is required, when using adhesive materials such as OCA and UV curable resin (OCR, LOCA), to attach the entire surface, while accurately controlling the film thickness and eliminating air bubbles and foreign substances.
Our puncher is applicable for film substrates which come in both roll or sheet, full or half punches at inner area of substrates, and full punches at the edges of final deliverables.? With combination of customized blades and servomotors it numerically controls speed and height, realizing precision processes that do not give stress at the cut surface and do not negatively influence the next steps of lamination process.
