Referring to FIG. 1 and FIG. 2 , the present embodiment provides a display device, including a display body 10, and a light guide assembly 20 disposed at the bottom of the display body 10. The front side of the display body 10 is used to display image information for viewing by a user. The light guide assembly 20 is used to receive an external remote control model for remote control to control the operation of the display device. In some embodiments, the light guide assembly 20 can also be used to receive a sound signal generated by a user and convert the sound into an electrical signal for controlling the operation of the display device to realize a voice interaction function.

The display body 10 mainly includes a housing 110, a rear housing 140 fixed to the back of the housing 110, a lower front housing 130 arranged at the lower end of the housing 110, a display panel 120 arranged at the front side of the housing 110, a light source (not shown in the figure) and an optical film group (not shown in the figure) arranged in the housing 110.
