The mobile terminal 100 further includes a display module 600. The display module 600 is covered with the base 1 and covers the receiving opening 101. Since the functional device 300 can flexibly protrude from the receiving cavity 10 or into the receiving cavity 10 according to the use requirement, the functional device 300 does not need to occupy the front space of the mobile terminal 100, and does not The screen ratio of the display module 600 is limited, so that the screen ratio of the mobile terminal 100 can be increased, which is beneficial to the full screen display development requirement of the mobile terminal 100.

The display module 600 includes a display area 601 and a frame area 602 disposed around the display area 601. The ratio of the area of the display area 601 to the area of the frame area 602 is greater than or equal to 9. In other words, the ratio of the display area 601 occupying the front surface area of the display module 600 is greater than or equal to 90%. At this time, the display module 600 can implement full screen display. The frame area 602 is used to arrange the driving cables to cause the display area 601 to perform screen display. When the functional device 300 is received into the receiving cavity 10, it overlaps with the display area 601.

The above is an embodiment of the present application. It should be noted that those skilled in the art can also make some improvements and retouching without departing from the principles of the embodiments of the present application. It is considered as the scope of protection of this application.
