Abstract
A terminal device and an infrared light transmission method are provided. A proximity light emission component and an infrared remote control emission component of the terminal device are in a shared mode. The proximity light emission component and the infrared remote control emission component share a same infrared lamp, lampshade, and appearance hole. A function of infrared remote control or a function of proximity light detection may be performed as required through one appearance hole, which can simplify hardware design and help to reduce costs. In addition, an infrared top path parallel to a screen of the terminal device and an infrared forward path perpendicular to the screen of the terminal device may be constructed based on an internal structure of the lampshade, and infrared light is transmitted through the infrared top path and the infrared forward path.
