In this embodiment, the electronic device 1 further includes a processor 70, the processor 70 is electrically connected to the light-emitting device 21, and when the processor 70 detects that the cover 100 is touched by the target object 30, the processor 70 controls the light-emitting device 21 to change the emitting angle of the emitted light 40, so that the emitted light 40 is emitted toward the target object 30.

The fifteenth embodiment of the present application can realize comprehensive fingerprint recognition by providing a plurality of transmitting devices and a plurality of receiving devices 22 on each side surface 122. In the present embodiment, by electrically connecting the processor 70 to the light emitting device 21, and when the processor 70 detects that the cover plate 100 is touched by the target object 30, the processor 70 may control the light emitting device 21 to change the emitting angle of the emitted light 40, so that the emitted light 40 is emitted toward the target object 30.

When the target object 30 touches the cover 100, the target object 30 generates a pressure on the cover 100, the pressure sensor generates a pressure signal, and the processor 70 receives the pressure signal and obtains the touched position, i.e. the position of the target object 30.

In addition, there are various implementations for the processor 70 to control the light emitting device 21 to change the exit angle of the emitted light 40, for example, the processor 70 may change the angle of the emitted light 40 by changing the assembly angle of the light emitting device 21 in the electronic device 1. Alternatively, the processor 70 may change the angle of the emitted light 40 by changing the angle of the light source in the light emitting device 21. Alternatively, the processor 70 may vary the angle of the emitted light 40 by varying the position of the light exit aperture in the light emitting device 21.

Optionally, when the electronic device 1 is in a black screen state and the processor 70 detects that the cover plate 100 is touched by the target object 30, the processor 70 controls the light-emitting device 21 to emit the emitted light 40 toward the target object 30. When the electronic device 1 is in the black screen state and the processor 70 does not detect that the cover 100 is not touched by the target object 30, or when the electronic device 1 is in the black screen state and the processor 70 detects that the cover 100 is touched by another object other than the target object 30, the processor 70 controls the light emitting device 21 not to emit the emission light 40. The present application can control that when the electronic device 1 is in the black screen state and the processor 70 detects that the cover plate 100 is touched by the target object 30, the processor 70 controls the light-emitting device 21 to emit light toward the target object 30, and when the electronic device 1 is in other times of the black screen state, the processor 70 controls none of the light-emitting devices 21 to emit light.
