Abstract: The present invention is a process for performing rigid-to-rigid substrate lamination implementing pressure-sensitive adhesive (PSA). The process may include pressurizing a first sealed cavity to a first pressure. The process may further include creating a vacuum within a second sealed cavity, the second sealed cavity being sealed from the first sealed cavity by a flexible membrane. The process may further include applying the first pressure to a laminate assembly stack via the flexible membrane, the laminate assembly stack including a first substrate, a second substrate, and a PSA layer, the PSA layer being positioned between the first substrate and the second substrate. The process may further include applying the vacuum created within the second sealed cavity to the laminate assembly stack. The applied first pressure and the applied vacuum promote intimate contact between the first substrate and the second substrate of the laminate assembly stack via the PSA layer.

The capping layer is positioned in the cavity of the fixture such that a first edge of the capping layer contacts the OLED assembly and a second edge of the capping layer is separate from the OLED assembly. Atmospheric pressure is reduced between the capping layer and the OLED assembly. The second edge of the capping layer is dropped such that the second edge of the capping layer is adjacent the OLED assembly.

Abstract: A method of adhering a first panel, such as an OLED assembly, to a second panel, such as a protective cover plate, is disclosed. An adhesive is applied to a face of at least one of the first and second panels. The first panel is positioned to be responsive to movement of any of a plurality of independently controlled expandable elements. The second panel is held adjacent the first panel. At least one of the expandable elements is selectively expanded so that a first edge of the first panel contacts a first edge of the second panel. The expandable elements are further selectively expanded so that the adhesive fully contacts the first and second panels.

Abstract: A method of sealing an Organic Light-Emitting Diode (OLED) assembly is disclosed. According to the method, a liquid adhesive is applied to substantially all of a surface of an OLED assembly. A region of increased thickness of liquid adhesive is formed adjacent to a first edge of the OLED assembly. A first edge of the protective cover is placed adjacent to the first edge of the OLED assembly. A second edge of the protective cover is moved toward a second edge of the OLED assembly such that the region of increased thickness of liquid adhesive is moved from being adjacent to the first edge of the OLED assembly to being adjacent to the second edge of the OLED assembly. The liquid adhesive is allowed to stabilize and is then cured.

Abstract: A flexible filter for use in filtering wavelengths of light that interfere with night vision awareness systems is disclosed. A filtering material is applied to a first flexible film in a substantially liquid form and is cured thereto using ultraviolet light. The filtering material filters wavelengths of light between about 610 and 930 nanometers when cured. A second flexible film is temporarily held in place by a support member. The second flexible film is applied to the cured filtering material and is fused thereto using a combination of increased temperature and pressure for a predetermined time. The first and second flexible films are made of polyurethane.

Abstract: A system and method for fabricating a polarizer for use in an LCD, which includes cutting said polarizer so that an absorption axis of the polarizer is aligned with an edge of the polarizer by using an optical sensor, coupled to a cutting machine, where the optical sensor uses a rotating reference polarizer to determine a null point of transmission through the polarizer and thereby determine any offset of the absorption axis with respect to an edge of the polarizer.

Abstract: A liquid crystal display optical component stack-up is created with reduced defects typically caused by adhesive materials used to attach optical components to the liquid crystal display, and with improved bond line control. First and second optical components are placed in a fixture having a plurality of pins extending from a bottom platen. A layer of silicone gel is placed between the first and second optical components. The plurality of pins orient the first and second optical components to achieve a desired alignment. A plurality of standoffs extending from the bottom platen and a top platen maintain a distance between the optical components and the platens to eliminate capillary action by the silicone gel adhesive, thereby aiding in bondline control.

Abstract: An optical component assembly is created with reduced defects in the adhesion and alignment between the optical components. A first rigid optical component is placed into a cavity. A second rigid optical component is placed into the cavity such that it is supported by a first support device which prevents a first end of the second rigid optical component from contacting a corresponding first end of the first rigid optical component. Air is evacuated from a chamber formed between the first and second rigid optical components. The support of the first support device is removed so that the first end of the second rigid optical component comes into contact with the first end of the first rigid optical component with a layer of adhesive material sandwiched therebetween. A force is applied to urge surfaces of the first and second rigid optical components toward one another to improve adhesion between the two.
