Abstract

A display device is disclosed. The display device includes a hinge module comprising a pair of hinge shafts arranged side by side, a pair of hinge brackets having one ends coupled to the hinge shafts, respectively, and the other ends in which slide slots are formed, a pair of slide brackets coupled to the slide slots, the slide brackets which are horizontally movable along the slide slots, and a pair of bodies coupled to the slide brackets, respectively, such that the display device may be foldable 0˜180 degrees to be folded and unfolded like a book.

Claims

1. A display device comprising:

a hinge module comprising a pair of hinge shafts arranged side by side, a pair of rotary plates rotatable along the hinge shafts, the pair of the rotary plates comprising guide projections projected in parallel, respectively; and

a guide plate comprising a guide slot extended in a predetermined direction, the guide plate is extended longitudinally, and

the guide projections are inserted in the guide slot and slide along the guide slot during the rotary plates rotating;

a pair of hinge brackets having one ends coupled to the hinge shafts, respectively, and the other ends in which slide slots are formed;

a pair of slide brackets coupled to the slide slots, the slide brackets which are horizontally movable along the slide slots; and

a pair of bodies coupled to the slide brackets, respectively.

2. The display device according to claim 1, wherein the pair of the hinge shafts are rotated in an opposite direction.

3. The display device according to claim 1, wherein a distance between both ends of the guide slot is corresponding to a spaced distance between the hinge shafts.

4. The display device according to claim 1, wherein the guide projections are formed in opposite to the hinge bracket with respect to the hinge shafts.

5. The display device according to claim 1,

wherein the guide slot comprises, a first slot and a second slot longitudinally arranged with the guide plate, in parallel;

and a vertical guide pin provided between the first slot and the second slot,

wherein the hinge module comprises a vertical slot provided between the first rotary plate and the second rotary plate, and

wherein the vertical guide pin inserted the vertical slot and move along the vertical slot.

6. The display device according to claim 1, wherein the hinge module further comprises,

a hinge housing configured to cover an outer circumferential portion of the hinge shafts, and

right and left portions of the hinge housing have curved surfaces having the same distance to the closer one of the hinge shafts.

7. The display device according to claim 6, wherein a one end of the slide bracket toward the hinge module comprises a concave surface having a curvature corresponding to the curved surface of the hinge housing.

8. The display device according to claim 7, wherein the portion of the slide bracket is formed of a flexible material having a restoring force.

9. The display device according to claim 1, wherein one end of the slide bracket has a variable distance to the hinge module, when sliding along the slide slot with respect to the hinge bracket.

10. The display device according to claim 9, further comprising:

a slide restricting portion provided between the bodies, with being bent in a U-shape.

11. The display device according to claim 10, wherein one of the slide restricting portion is positioned in one body and the other end is positioned in the other body and a middle bent portion is positioned in the hinge module.

12. The display device according to claim 1, wherein a distance (a) between the hinge shafts is a value gained after dividing the sum of the squares on the distance (d) between the two bodies and the thickness (c) of the bodies by a multiple of the thickness (c) of the bodies (a=(c²×

d²)/(2c)).

13. The display device according to claim 12, wherein a horizontally moving distance of the slide bracket is less than a half of the distance (d) between the bodies.

14. The display device according to claim 1, wherein a predetermined portion of the body comprises an inserting portion having a size corresponding to a size of the hinge module.
