In the using state, the display device is in a vertical screen mode, and the display device can be used as a common television, and also can be used for watching television, talking or being used as a dressing mirror.

In a third schematic view of the usage state of the display device, the front side of the display main body 100 is vertically and horizontally disposed. In this use state, the display device is in a desktop mode, and the display device may be used for table top use for playing games, entertainment, learning, or work.

In a fourth schematic usage state of the display device, the front side of the display main body 100 is obliquely arranged and forms an angle of 45 degrees with the horizontal. The display equipment is in a slant screen mode and can be used for market display or ordering and the like.

In the present invention, the adaptor unit 300 is rotatably connected to the base 200, the rotation axis of the adaptor unit 300 is obliquely disposed, the display main body 100 is connected to the adaptor unit 300, and the rotation of the adaptor unit 300 relative to the base 200 drives the display main body 100 to rotate. The included angle between the rotation axis of the switching unit 300 and the front side of the display main body 100 is an obtuse angle or an acute angle, that is, the front side of the display main body 100 is not perpendicular to the rotation axis of the switching unit 300, and the switching unit 300 rotates around the rotation axis to drive the front side of the display main body 100 to be at different angles relative to the horizontal plane, so that the multi-angle adjustment of the display main body 100 is realized, and the display device can adapt to more use scenes.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
