4 . The terminal wireless charging cradle of claim 1 , wherein the recess comprises:
a first surface recessed with a first depth with respect to an upper surface of the body, the supporter at the first position being seated thereon; and
a second surface recessed with a second depth deeper than the first depth with respect to the upper surface of the body, located in front of the first surface, and supporting a lower end of the supporter at the second position.
5 . The terminal wireless charging cradle of claim 4 , wherein the recess further comprises a third surface connecting the first surface and the second surface and located at a lower rear side of the supporter at the second position.
6 . The terminal wireless charging cradle of claim 5 , wherein the third surface comprises:
a flat portion formed in parallel with a rear surface of the supporter at the second position and connected to the second surface; and
a curved portion connecting the flat portion and the first surface in a round manner.
7 . The terminal wireless charging cradle of claim 6 , wherein the guide groove comprises:
a first groove extending horizontally; and
a second groove extending to be inclined downward in a direction parallel to the flat portion from a front end of the first groove.
8 . The terminal wireless charging cradle of claim 1 , wherein a front surface of the supporter at the second position is spaced apart rearward from an inner front surface of the recess.
9 . The terminal wireless charging cradle of claim 1 ,
wherein a first hole, through which a cable connected to the wireless charging circuit passes, is formed in at least one of the pair of protrusions, and
wherein a second hole communicating with an internal space of the body and having a shape corresponding to the guide groove and having the cable passing therethrough is formed in at least one of the pair of guide grooves.
10 . The terminal wireless charging cradle of claim 1 , wherein a front surface of the supporter is inclined in an inclined direction toward the rear toward an upper side when the supporter is at the second position.
11 . A display device comprising:
a base;
a stand vertically extending upward from the base;
a head provided with a display and connected to the stand; and
a cradle located at a lower height than the head and connected to the stand,
wherein the cradle comprises:
a body disposed horizontally;
a recess formed to be stepped downward from an upper surface of the body;
a supporter having a wireless charging circuit built therein and movable between a first position laid down in the recess and a second position erected to protrude upward from the recess;
a pair of guide grooves formed in both inner surfaces of the recess; and
a plurality of protrusions protruding from both lower sides of the supporter into the pair of guide grooves and sliding along the pair of guide grooves when the supporter moves.
12 . The display device of claim 11 , further comprising a processor configured to mirror a screen displayed on a display of a terminal supported on the supporter to a display of the head.
13 . The display device of claim 11 , wherein an upper surface of the body comprises:
a first region in which the recess is formed; and
a second region formed to be stepped lower than the first region and located opposite to the stand with the first region interposed therebetween.
14 . The display device of claim 11 ,
wherein a first hole is formed in at least one of the pair of protrusions,
wherein a second hole communicating an internal space of the body and having a shape corresponding to the guide groove is formed in at least one of the pair of guide grooves,
wherein a third hole communicating with the inside of the body is formed in a circumferential surface of the body,
wherein a fourth hole facing the third hole and communicating with the inside of the stand is formed in the stand, and
wherein a cable connected to the wireless charging circuit sequentially passes through the first hole, the second hole, the third hole and the fourth hole and extends into the stand.
15 . The display device of claim 11 ,
wherein a periphery of the head is connected to one side of the stand, and
wherein the cradle is connected to the other side of the stand.
