Abstract: A display substrate, a manufacturing method therefor, and a display device are provided. The display substrate includes a base substrate, sub-pixels and an isolation portion, and each sub-pixel includes a light-emitting function layer. The isolation portion includes a first sub-isolation portion and a second sub-isolation portion. The first sub-isolation portion is between the second sub-isolation portion and the base substrate. The second sub-isolation portion includes a protrusion protruding relative to an edge of the first sub-isolation portion, the second sub-isolation portion facing one of adjacent sub-pixels is different in shape from the second sub-isolation portion facing the other one; or, a slope angle between a side surface of the first sub-isolation portion or the second sub-isolation portion facing one sub-pixel and a plane parallel to the base substrate is 60° to 120°. At least one film of the light-emitting function layer is disconnected at the isolation portion.

Abstract: Embodiments of the present invention relate to a back cover releasing mechanism, a back cover and a mobile device using the same. The back cover releasing mechanism for a mobile device comprises an elongated side key comprising a first end and a second end, configured to be mounted along and in parallel with a side of the mobile device; and a sliding member comprising a base portion configured to be coupled to the side key, and a latch portion, wherein the latch portion is configured to engage a back cover of the mobile device, and wherein the latch portion is also configured to be disengaged from the back cover of the mobile device if the first end and the second end of the side key are both pressed toward the interior of the mobile device and the base portion of the sliding member is forced to move toward the interior of the mobile device.

Abstract: A cover, a portable electronic device using the same and a method for manufacturing the same are provided. The cover comprises a transparent layer one surface of which is a textured surface. The cover also comprises a light guide formed in the transparent layer, one of interior surfaces of the light guide being the textured surface, wherein the light guide is for light guiding such that at least one beam of colored light is guided through the transparent layer and dispersed out of the transparent layer at a surface opposite to the textured surface as a result of being incident on the texture. With the cover according to embodiments of the present invention, a portable electronic device to which the cover is attached could be illuminated with different colored lights.

Abstract: An apparatus for use with an optical mouse and a method of manufacturing the apparatus are provided. In one embodiment, the apparatus includes a board having a surface operable to be in contact with a window of the optical mouse; and a lifting member operable to move the surface away from the window. In response to a distance between the surface and the window being below or exceeding a predefined threshold, a lateral movement of the surface with respect to the window being detectable or undetectable, respectively, by the optical mouse. The apparatus provides a handy tool to be used by an end user, so that he/she is able to use an existing mouse in the air, and control the cursor by manually operating the board and the lifting member in an intuitive and ergonomic manner.

Abstract: A switch and a method of manufacturing the switch are provided. In one embodiment, the switch comprises a switch assembly adapted to receive a first force in a first direction; and a protective member arranged on a substrate and adapted to receive the switch assembly, the protective member comprising a spring portion applying a second force to the switch assembly in a second direction that is opposite to the first direction, the switch assembly being adapted to be moved relative to the substrate in response to the first force exceeding a predefined threshold value. The switch is capable of absorbing excessive energy by a force applied on the switch, thus preventing the excessive energy breaking the substrate to which the switch is mounted.
