The function module 20 may receive and/or emit a light beam through the display module 10. The display module 10 is at least partially disposed within the housing 30. Generally, the side of the display module 10 for the user to browse and operate is called the front side, and the opposite side is called the back side. In other embodiments of the present invention, the housing 30 includes a bottom frame and/or a side frame.

In other embodiments of the present invention, the housing 30 may be omitted.

The function module 20 can receive and/or emit the light beam 102 through the display module 10. The light beam 102 is visible light or infrared light.

In an embodiment of the present invention, the external light beam 102 reflected by the external object passes through the liquid crystal display panel 11, the opening 101 reaches the functional module 20. The functional module 20 obtains a two-dimensional image or/and a three-dimensional image of the external object according to the received light beam sensing, for example.
