Abstract: A display device control method includes when an operation on an on-screen display (OSD) input device is received, determining whether a signal generated by operating the OSD input device is currently sent to an OSD system or an operating system (OS); and when the signal generated by operating the OSD input device is currently sent to the OS-system, switching, according to a control signal generated by the OSD input device, the control signal from being sent to the OSD system to being sent to the OS-system. This application further provides a display device.

Abstract: The application discloses an electronic device, including a flexible display, a first housing, a second housing, and a flexible connecting piece, where two sides of the flexible connecting piece are connected to the first housing and the second housing, and the flexible display is fastened to the first housing, the flexible connecting piece, and the second housing. A plurality of first slits are disposed on a side that is of the first housing and that faces away from the flexible display; a plurality of second slits are disposed on a side that is of the second housing and that faces away from the flexible display; a plurality of third slits are disposed on a side that is of the flexible connecting piece and that faces away from the flexible display; and extension directions of the first slit, the second slit, and the third slit are parallel to a first direction.

Abstract: A wireless broadband device includes: a main body and an end cover, where the main body and the end cover are assembled to form a whole; a first battery is carried in the main body and configured to supply power to a circuit of the main body; a second battery is built in the end cover, where a power output contact of the second battery emerges from an inner side of the end cover; the inner side of the end cover contacts the main body; and the power output contact of the second battery contacts an exposed power input contact point of the circuit of the main body, and when an output voltage of the first battery is smaller than the minimum required voltage for supplying power to the circuit of the main body, the circuit of the main body switches to the second battery for power supply.
