  • Patent number: 9934735
    Abstract: A display control method and an electronic device are described. The electronic device includes a first body and a second body. Two sides of the first body include a first display area and a second display area respectively. The method includes: acquiring space position information of the first body and the second body, determining whether the space position information satisfies a first space predetermined condition, and obtaining a first determining result; detecting a first included angle between the first body and the second body if the first determining result indicates that the space position information satisfies the first space predetermined condition; determining whether the first included angle satisfies a first included angle predetermined condition, and switching an operating state of the electronic device to the triangle supporting state if the first included angle satisfies the first included angle predetermined condition.

  • Patent number: 8886968
    Abstract: A method, a device and a terminal for controlling dual-processor switch are disclosed in the present invention. The terminal may include an X86 processor system, an embedded processor system and a switch module connecting the X86 processor system with the embedded processor system. The switch module may be coupled to the peripheral device of the terminal. The method includes that the switch module is controlling the peripheral device by receiving a control signal from the X86 processor system, the switch module receiving a triggering signal for switching to the embedded processor system. The switch module wakes up the embedded processor system, switching to receive a control signal sent from the embedded processor system, and controlling the peripheral device by using the control signal from the embedded processor system. The method may enable the embedded processor system to control the peripheral device of the terminal individually through the switch module.
