In this embodiment, the first screen 11 may have a display layer 110c and a touch layer 110a. The display layer 110c is used to display the multiple icons. When the user's finger presses the icon of the first screen 11, the detection module 25 detects the touch operation performed by the user on the first screen 11 through the touch layer 110a. The activation module 28 activates the camera element 40, and the facial recognition module 17 and/or the iris recognition module 19 obtain the facial features and/or iris features of the user through the camera element 40.

In step S402, the judging module 27 uses the face recognition module 17 and/or the iris recognition module 19 to determine whether the facial features and/or iris features of the user match the face pre-stored in the memory 10 Feature and/or iris feature, and the judging module 27 judges whether the touch operation selects one of the multiple icons. If the facial features and/or iris features of the user do not match the facial features and/or iris features pre-stored in the memory 10, or the touch operation does not select one of the multiple icons 1. The judgment module 27 ignores the touch operation and returns to step S401. If the user’s face The feature and/or iris feature matches the facial feature and/or iris feature pre-stored in the memory 10, and the touch operation selects one of the multiple icons, then step S403 is entered.

In step S403, the activation module 28 unlocks the electronic device 100 and activates the second screen 12.

In step S404, the display module 29 controls the second screen 12 to display the user interface corresponding to the selected icon.
