Abstract: The present invention discloses a display including a display panel and a light redirecting film disposed on the viewing side of the display panel. The light redirecting film comprises a light redistribution layer, and a light guide layer disposed on the light redistribution layer. The light redistribution layer includes a plurality of strip-shaped micro prisms extending along a first direction and arranged at intervals and a plurality of diffraction gratings arranged at the bottom of the intervals between the adjacent strip-shaped micro prisms, wherein each of the strip-shaped micro prisms has at least one inclined light-guide surface, and the bottom of each interval has at least one set of diffraction gratings, and the light guide layer is in contact with the strip-shaped micro prisms and the diffraction gratings.

Abstract: A stylus pen includes a rod body, a cover body, and a positioning module. The rod body includes a main body portion and a sleeve portion connected to each other. The cover body is configured to be sleeved onto the sleeve portion, and is configured to move relative to the rod body to a first position and a second position along a first axial direction. The positioning module is disposed between the sleeve portion and the cover body, and is configured to generate changes of force to the cover body and the rod body in a second axial direction when the cover body moves to the first position and the second position relative to the rod body.

Abstract: A stylus includes a body, a carrying structure, and a tip structure. The carrying structure is disposed at the body and has a ring-shaped positioning portion, and the ring-shaped positioning portion has an axial hole. The tip structure is disposed on the carrying structure, a segment of the tip structure penetrates the axial hole, and the ring-shaped positioning portion entirely covers the segment of the tip structure along a peripheral direction of the axial hole.

Abstract: A keyswitch device includes a base plate, a hook, a scissors-like linkage mechanism, a keycap, and a blocking structure. The hook is located on the base plate. The scissors-like linkage mechanism is located on the base plate and includes a connection member. The connection member includes a shaft rotatably engaged with the hook. The keycap is engaged with the scissors-like linkage mechanism and configured to move relative to the base plate with the guidance of the scissors-like linkage mechanism. The blocking structure is located on the base plate. When the keycap is located at a highest position relative to the base plate, the blocking structure and a part of the connection member abut against each other.

Abstract: An electric shock proof socket circuit includes a power supply module for stepping down and rectifying an input voltage and then providing the step-down and rectified voltage to a detecting module and a switching module. The detecting module includes a light-emitting unit and a light-receiving unit. The light-emitting unit is used for emitting light for the light-receiving unit. Whether the light from the light-emitting unit is received by the light-receiving unit or not makes the detecting module send corresponding control signals. The switching module controls power output of the socket circuit according to the control signals for preventing an electric shock danger. So the electric shock proof socket circuit has the advantages of security and convenience.

Abstract: A hinge is mounted between a cover and a base of an electronic device and has a pivoting bracket, a rotating bracket and a collar assembly. The pivoting bracket is mounted on the stationary leaf and has a tube protrudes transversely on an outside wall of the pivoting bracket. The rotating bracket is mounted around the tube and has at least one detent formed in a top surface of the rotating bracket. The collar assembly is mounted around the tube and has a positioning collar. The positioning collar has at least one protrusion selectively engaging the at least one detent. Even though the engaging surface between the at least one detent and the at least one protrusion is worn away, the interface between the brackets stays flat and the cover of the electronic device remains mounted stably on the base.
