  • Patent number: 10234923
    Abstract: Methods and devices are provided for waking up a screen in the field of application of electronic technologies. The method may be implemented by a device including a screen and a frame at least partially surrounding the screen. In the method, the device activates at least one temperature transducer according to a predetermined sequence when the screen is in an off state, where the at least one temperature transducer is disposed at least partially in the frame. The device may obtain a temperature measurement through the activated temperature transducer. When any one of the temperature measurement is within a preset range of temperature, the device may trigger the screen to be switched from the off state to an on state.
