Each respective one of the overlay applicators can include a respective overlay configured to be applied to a respective surface of each of the electronic devices. The machine can be configured to facilitate applying, individually at different times, the respective overlays to the respective surfaces of the electronic devices. Other embodiments are described.

Systems and apparatus for protecting a mobile device. The system includes a screen protector configured to be applied to a screen of the mobile device. The system also includes a cap configured to receive an end of the mobile device and prevent movement of the mobile device relative to the screen protector. The system also includes a pivot strip connecting the cap and the screen protector and being configured to facilitate a pivoting of the screen protector relative to the cap and establish alignment of the screen protector with the screen of the mobile device.

An apparatus and/or method for installing a screen protector on an electronic device, for example using a wet application process. The apparatus includes a support member for supporting the electronic device and a clamp mechanism for clamping the electronic device in a fixed position on the support member. A tack assembly is used to tack the screen protector to the electronic device. The tack assembly includes an actuator that, once actuated, causes a tack member to apply a force onto the screen protector which tacks the screen protector to the electronic device and prevents misalignment. Finally, a roller assembly is actuated so that a roller member moves across the screen protector to bond the screen protector to the electronic device and remove any excess liquid that may exist between the screen protector and the electronic device.

A method of manufacturing a display unit including: preparing an optical film; forming a first alignment mark on the optical film; forming a cut-out line, corresponding to a predetermined closed curve layout, on the optical film based on a position of the first alignment mark; preparing a panel having a second alignment mark; aligning the optical film and the panel based on the positions of the first alignment mark and the second alignment mark; and laminating the optical film, after the processing of forming the cut-out line, on the panel.

A film-application apparatus includes a body including a first body half, a second body half, and a hinge coupling the body halves; and a squeegee blade movable from a first position relative to the body to a second position relative to the body. The second body half is rotatable about the hinge relative to the first body half to a closed position. When the second body half is in the closed position, the body includes a top ring and a bottom ring both centered on an axis and defining an axial gap therebetween. When the second body half is in the closed position and the body is enclosing a sensor having a cylindrical sensor window, the axial gap exposes the cylindrical sensor window, and moving the squeegee blade from the first position to the second position covers substantially an entire surface area of the cylindrical sensor window.

A membrane bearing device, a membrane attaching apparatus and a method for attaching a membrane are provided in embodiments of the disclosure. The membrane bearing device includes: a base plate, comprising a first bearing surface configured to bear a membrane; and a roller, which is rotatably mounted onto the base plate, and is configured to transfer and attach the membrane from the first bearing surface to a substrate onto which the membrane is to be attached, by rolling on the membrane.

A cover layer is joined to an object by a pressing force and mechanical vibration. The cover layer has a cover layer contact surface, and the object has an object contact surface, and the cover layer contact surface and the object contact surface face each other. At least one of the cover layer and the object include a joining material. The cover layer contact surface is brought into contact with the object contact surface, and a sonotrode presses the cover layer against the object and applies mechanical vibration to an outer surface of the cover layer for a time sufficient for activating the joining material. Cover layer and object are conveyed relative to the sonotrode in a continuous manner in a conveying direction throughout the steps of arranging, of bringing into contact, of pressing and of applying vibration.

Disclosed herein is a screen protector assembly and a screen protector applicator comprising a screen protector assembly and an applicator tray, the screen protector assembly comprising a cover layer, a screen protector layer and a retention layer, wherein: the cover layer is bonded on a first side of the screen protector layer by a first glue layer provided on the screen protector layer; the retention layer is bonded on a second side of the screen protector by a second glue layer provided on the retention layer; and an interlayer is provided between the retention layer and the screen protector layer. The screen protector applicator has a simple structure, and can store and protect the screen protector assembly before application of the screen protector layer to the screen. In the process of screen protector application, the operation method is simple and convenient.

An apparatus for assisting in affixing a screen protector to a display of an electronic device. The apparatus includes a base having a platform for supporting the electronic device, a lid attached to the base, and a positioning mechanism for aligning the electronic device on the platform. The positioning mechanism includes a first positioning jaw movable between a first and a second position. The positioning jaw includes a first surface configured to contact the first corner of the electronic device and a second surface configured to contact the second corner of the electronic device when the first positioning jaw moves from the first position to the second position. Moving the lid from a first position to a second position at least partially covering the electronic device moves the first positioning jaw from the first position to the second position.

A method of attaching a flexible screen to a cover plate includes: adhering a first adhesive film layer of a laminated adhesive film to a mounting surface of a cover plate, in which the laminated adhesive film includes the first adhesive film layer, a second adhesive film layer and a second release layer, the second release layer is releasably attached to the second adhesive film layer, the first and second release layer are respectively disposed on both sides of the second adhesive film layer; releasing the second release layer from the second adhesive film layer; and adhering the second adhesive film layer to a flexible screen such that the cover plate is attached to the flexible screen. A tight attachment between the laminated adhesive film and the cover plate can be achieved.
