7. The glasses-free 3D display device of claim 6, wherein:

the cover frame comprises a fastening portion detachably coupled to the display device; and

a distance between a leading end of the fastening portion and the three-dimensional film is less than a thickness of the display device.

8. The glasses-free 3D display device of claim 2, wherein the 3D viewing cover further comprises a secondary buffer member between the cover frame and the transparent plate.

9. The glasses-free 3D display device of claim 1, wherein the 3D viewing cover is coupled to the display device by an elastic force.

10. The glasses-free 3D display device of claim 1, wherein the cover setting program is configured to display a cover alignment pattern on the flat panel display of the display device.

11. The glasses-free 3D display device of claim 10, wherein the cover setting program is configured so that, when the displayed cover alignment pattern is touched, one or more of the setting parameters of the 3D viewing cover are changed.

12. The glasses-free 3D display device of claim 11, wherein the setting parameters of the 3D viewing cover comprise a slanted angle, a rendering pitch, and an offset of the three-dimensional film.

13. A setting method of a glasses-free three-dimensional (3D) display device, the setting method comprising:

executing a cover setting program in the display device for a 3D viewing cover mountable on the mobile device;

displaying a cover alignment pattern image on the flat panel display of the display device based on an eye tracking operation for a face of a user;

adjusting the cover alignment pattern image; and

storing, in a storage of the display device, first setting parameters of the adjusted cover alignment pattern image.

14. The setting method of claim 13, further comprising:

receiving an input of design parameters of the 3D viewing cover into the cover setting program,

wherein the displaying the cover alignment pattern image comprises displaying the cover alignment pattern image on the flat panel display of the display device based on the eye tracking operation for the face of the user and based on the design parameters of the 3D viewing cover.

15. The setting method of claim 13, wherein the displaying the cover alignment pattern image comprises:

determining a distance from the display device to eyes of the user by performing the eye tracking operation for the face of the user;

obtaining the cover alignment pattern image based on design parameters of the 3D viewing cover and the determined distance from the display device to the eyes of the user; and

displaying the obtained cover alignment pattern image on the flat panel display.

16. The setting method of claim 14, wherein the design parameters comprises a slanted angle, a rendering pitch, and an offset of the three-dimensional film of the 3D viewing cover.

17. The setting method of claim 16, wherein the cover alignment pattern image displayed on the flat panel display is movable by user input to change values of the first setting parameters.

18. The setting method of claim 13, further comprising:
