Abstract: A resistive touch sensor includes a base layer, a sensor top sheet positioned in spaced apart relation to a base layer, and a peripheral edge seal formed between the sensor top sheet and the base layer. The sensor further includes a first adhesive layer bonded on a peripheral edge portion to the sensor top sheet, and a second adhesive layer, inset relative to the peripheral edge seal, positioned between the first adhesive layer and the sensor top sheet. The second adhesive layer is bonded on one side to the first adhesive layer and an opposing side to the sensor top sheet corresponding to a portion of a touch active area. The second adhesive layer causes a planarity change in the sensor top sheet proximate the peripheral edge seal thereby increasing the usable area and improving uniformity of touch force across the sensor.

Abstract: A laminating machine and process for applying an optically clear adhesive film to a glass substrate includes a porous belt assembly with a plurality of vacuum pumps. The vacuum pumps define different, separately adjustable vacuum zones on the surface of the porous belt. The porous belt is driven linearly so that an optically clear adhesive does not move relative to the porous belt, but does move relative to the table, allowing the adhesive to be controlled to a compressive, neutral, or tensile state while being nip-rolled to the substrate. Since there is no motion of the film relative to the belt, scratching, stretch elongation, dimensional errors, and other slip induced damage is eliminated.

Abstract: A high-speed lamination machine includes a hinged, clamshell lid, and clamped lamination chamber that uses localized and thermally isolated heating and stepper driven separation pin motion. Pneumatically actuated rollers in a track clamp the lamination chamber closed during operation. The clamshell design obviates the need for a hydraulic press and makes the lamination chamber easily accessible to other automated systems, so robots may be used to place lamination elements within the chamber.

Abstract: A laminating machine includes UV curing elements within the process chamber to cure a UV curable adhesive in a laminating stack while being heated in an autoclave. In an automated process, the laminating machine applies pressure to the stack for pressure sensitive adhesion, then autoclave heating and simultaneous UV curing. The UV curing elements are disposed in the body of the process chamber, the lid of the process chamber, or a separate appliance. The appliance can be releasably attached to the process chamber body or lid. The laminating machine is programmed for specific autoclave and UV exposure profiles specific to the UV curable adhesives being used.

Abstract: A system and related method for force-sensitive emissive display incorporates a force sensing device, such as a force-sensitive resistor or frustrated total internal reflection (FTIR) assembly, bonded to a flexible film/film resistive touch sensor and an emissive display surface. The film/film resistive touch sensor may detect contact with the display surface and transmit the detected contact to the force sensing device, which determines a magnitude or degree of touch force associated with the detected contact. A display controller of the force-sensitive emissive display system may adjust the displayed content, or execute other responsive actions, based on the detected touch force as well as the position of the contact relative to the display surface, as determined by the film/film resistive touch sensor or by the force sensing device.
