A two-stage application device is disclosed for installing a screen protector on a display screen of a screen-mounted device. The application device includes a base, a first actuating lever, and a second actuating lever. The base includes an accommodation and a support, wherein the support defines first grooves and second grooves. The first actuating lever has first controlled pivot portions guided and limited by the first grooves, a first pressing portion, a first arm, and a body with a positioning protrusion. The second actuating lever has second controlled pivot portions guided and limited by the second grooves, a second pressing portion, a second arm, and a body. A kit is also disclosed for protecting a display screen of a screen-mounted device, which includes a two-stage application device, and at least one screen protector including a protective film with at least one adhesive layer, and a backing sheet.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller apparatus may be used to apply the protective film on the surface of the electronic device. The roller apparatus may include an opening for receiving a display peg.

Disclosed is a case for attaching a screen protector film for a mobile terminal. The case for attaching a screen protector film for a mobile terminal includes: a film housing that has a film seat for keeping a screen protector including a separation film and a screen protector film that is separated from the separation film to be attached to a screen of a mobile terminal; and a movable member that is coupled to and separated from the film housing by moving in a movement direction parallel with the longitudinal direction of the screen protector and has a terminal seat disposed perpendicular to the movement direction and corresponding to the upper end or the lower end of a mobile terminal, in which the movable member is connected to the screen protector film at a predetermined area around the terminal seat.

An apparatus to apply a foam seal to a part is provided. The apparatus comprises a receiving device to secure the part, a loading device and a driving device to drive the loading device. The receiving device includes a housing, a first rod coupled to the housing and at least partially disposed in the housing and a resilient member connected between the housing and the first rod at a radial direction. The loading device includes an actuating member and a holding member to hold the foam seal. The driving device is configured to move the loading device between a loading position and an application position and further drive the actuating member and the holding member to rotate around an axis parallel to the first rod. The actuation member contacts the housing while rotating and the foam seal on the holding member contacts the part at the application position.

Proposed is the film attachment device including: a position setting plate including a main body in which a longitudinal hole extending in a forward-backward direction is formed, and a plurality of elastic members, first end portions of which protrude downward from the main body in a state of being arranged to be spaced apart in such a manner as to surround a position setting space, and second end portions of which extend upward toward the main body and come into close contact with a terminal being inserted into the position setting space; an auxiliary member in which first and second rectangular through-holes are formed to be positioned a predetermined distance apart in such a manner as to communicate with the longitudinal hole, and which is arranged on a lower surface of the main body; and a protective film arranged to cover bottoms of the first and second rectangular through-holes.

An elevator maintenance kit is provided for surfacing an elevator sheave that engages with an elevator tension member. The kit includes a substrate with an adhesive backing, and a substrate applicator that is operable to apply the substrate to the sheave as the sheave is rotated. The adhesive backing is operable to attach the substrate to the sheave during the sheave rotation.

A system and method for applying a screen protector to a handheld electronic device may provide a frame to surround the device and secure a screen protector over the device prior to final installation. The frame may provide supports to interface with screen protector cutouts to ensure a uniform fit. For rigid protectors, sets of small teeth may secure the protector to the frame and provide audible confirmation of proper mounting and eventual installation. When fitted over a device, a user may then push the screen protector downward for a perfect mounting of the protector to the device every time.

A method of manufacturing a curved display device is disclosed. In one aspect, the method includes providing a frame, providing a flexible display panel and attaching a first area of the flexible display panel to the frame. The method also includes attaching a second area of the flexible display panel to the frame, wherein the providing of the flexible display panel comprises attaching a release paper to a surface of the flexible display panel, the release paper comprising first and second release areas respectively corresponding to the first and second areas of the flexible display panel. The method further includes removing the first release area from the flexible display panel before attaching the first area and removing the second release area from the flexible display panel before attaching the second area.

A method and an apparatus for manufacturing an optical display device by sequentially peeling a plurality of optical film sheets continuously supported on a long web of a carrier film and laminating the plurality of optical film sheets to a plurality of panel components are provided.
