at least a portion of the antenna element is disposed within the clearance area;
the antenna element is connected to the first RFIC; and
the first RFIC is disposed on a first flexible printed circuit (FPC) of the screen, a screen integrated circuit (IC) and a touch IC are further disposed on the first FPC, and the first FPC is connected to the mainboard through a first board to board (BTB) connector; wherein
the antenna element is a millimeter-wave antenna element; and
the terminal device further comprises a second FPC and a second RFIC, the first FPC is disposed at a first end in a length direction of the screen, and the second FPC is disposed at a second end in the length direction of the screen; the second RFIC is disposed on the second FPC, and the second FPC is connected to the mainboard through a second BTB connector; and millimeter-wave antenna element is disposed at both the first end and the second end, a millimeter-wave antenna element located at the first end is connected to the first RFIC, and a millimeter-wave antenna element located at the second end is connected to the second RFIC.

2. The terminal device according to claim 1 , wherein
the clearance area is a reserved area of the screen;
the millimeter-wave antenna element comprises a millimeter-wave antenna and a feeding structure;
a millimeter-wave signal source is disposed in the first RFIC;
the millimeter-wave antenna is disposed within the clearance area; and
the millimeter-wave antenna is connected to the millimeter-wave signal source through the feeding structure.

3. The terminal device according to claim 2 , wherein the feeding structure is disposed on the first FPC.

4. The terminal device according to claim 3 , wherein the millimeter-wave antenna comprises a first radiator and a second radiator, the first radiator is connected to the millimeter-wave signal source through the feeding structure, and the second radiator is grounded.

5. The terminal device according to claim 4 , wherein the first radiator and the second radiator are symmetrically disposed.

6. The terminal device according to claim 4 , wherein the first radiator is an indium tin oxide (ITO) radiator.

7. The terminal device according to claim 4 , wherein the second radiator is formed by extending part of a ground wire in an indium tin oxide (ITO) circuit of the screen into the clearance area.

8. The terminal device according to claim 4 , wherein the first radiator extends to a link area between the screen and an FPC, and the first radiator is connected to the feeding structure.

9. The terminal device according to claim 2 , wherein a housing of the terminal device comprises a signal reflection area, and after a signal sent by the millimeter-wave antenna is reflected through the signal reflection area, a direction of a reflected signal is a same as an orientation of the screen.

10. The terminal device according to claim 9 , wherein the housing comprises a front shell or a middle frame, and the signal reflection area is located in the front shell or the middle frame.

11. The terminal device according to claim 9 , wherein there is a space between the signal reflection area and the millimeter-wave antenna.

12. The terminal device according to claim 1 , wherein the clearance area is located at a top area of the screen, a side area of the screen, or a corner area of the screen.

13. The terminal device according to claim 1 , wherein there is a clearance area at the second end.
