1. A terminal device, comprising:
an infrared lamp, a lampshade, an infrared emission hole, an infrared controller, a cover glass, and a display screen; wherein
the infrared lamp is located below the cover glass, a lamp head of the infrared lamp is located below the lampshade, and the display screen is located below the cover glass;
ink is deployed on a lower side of the cover glass and in a projection area of a skirt of the lampshade on the cover glass, to form an ink area;
the infrared controller is connected to the infrared lamp and is configured to control the infrared lamp to emit infrared light which is transmitted through a first infrared path and a second infrared path, wherein the infrared light is used for proximity light detection or infrared remote control, the first infrared path is an infrared path that starts from a lamp head area of the infrared lamp, passes along an inner cavity of the lampshade, and faces a first surface of the terminal device, and the second infrared path is an infrared path that starts from the lamp head area of the infrared lamp, passes along the skirt of the lampshade, and faces the display screen;
the infrared emission hole is located on the first surface of the terminal device, so that the infrared light transmitted along the first infrared path is transmitted to the outside of the terminal device through the infrared emission hole; and
the infrared light transmitted along the second infrared path is transmitted to the outside of the terminal device through the ink area.
