Display screen component and electronic device

An electronic device, comprising:

• a housing;
• a display screen component coupled to the housing;
• and
• a cover plate coupled to the display screen component and configured to cover the display screen component,
• wherein the display screen component comprises:
• a display screen comprising a display area and a non-display area;
• and
• a sensor unit arranged below the display screen, and comprising a signal emitter and a signal receiver, the signal emitter being arranged below the non-display area and aligned with at least part of the non-display area, and the signal receiver being arranged below the display area and aligned with at least part of the display area,
• wherein the non-display area comprises a functional portion configured to be passed through by a detecting signal emitted by the signal emitter to outside,
• the signal receiver is configured to receive a reflected signal from the outside through the display area of the display screen, in which the detecting signal is changed into the reflected signal after being reflected by an external object.
