Abstract: The disclosure provides a method for controlling a camera module in an electronic device. The camera module is removable between a first position received in a body of the electronic device and a second position exposed from the body. The method includes: driving the camera module to slide to the second position in response to receiving a first face recognition request; maintaining the camera module in the second position for a first duration in response to acquiring a release request on the camera module; and driving the camera module to slide to the first position in response to not receiving a second face recognition request within the first duration.

Abstract: A light guide assembly includes a light guide plate and a light guide strip around the periphery of the light guide plate, where a plurality of light-transmitting holes are formed on one side of the light guide strip facing to the light guide plate, and at least one end of the light guide strip is an light incident side. The light is incident to the inside of the light guide strip from the light incident side, and then is incident into the light guide plate from the light-transmitting holes on the side of the light guide strip, and thus becomes a surface light source.

Abstract: The disclosure provides a method for controlling a camera module. The camera module is removable between a first position received in a body of the electronic device and a second position exposed from the body. The method includes: driving the camera module to slide to the second position based on a call request on the camera module sent by a camera application, in response to the camera application running in a system foreground; determining whether a current application is a preset application, in response to an application in the system foreground switching from the camera application to the current application; determining whether receiving a call request on the camera module sent by the current application in response to the current application being the preset application; and maintaining the camera module in the second position within a preset duration, in response to not receiving the call request.

Abstract: A back light unit and a display device are proposed. The back light unit includes a light guide plate and multiple light emitting diodes, wherein the multiple light emitting diodes are disposed on a light entrance surface of a side end of the light guide plate, the light entrance surface of the light guide plate is disposed with at least one groove, and the at least one groove is disposed between at least part of adjacent light emitting diodes.
