## Abstract

The present invention provides a hinge for a display device. A hinge for a display device according to the present invention, which connects and folds/unfolds first and second plates in a display device, includes: a soft plate member that is bendable while connecting first and second plates; a plurality of ribs formed at regular intervals at both sides of the soft plate member; a link means connecting the ribs and composed of first and second link and individually rotating with the bending of the soft plate member; and a fixing mechanism generating a fixing force by spring elasticity to control the rotation angle of the first and second links of the link means.

## Claims

### Claim 1

A hinge for a display device which connects and folds/unfolds first and second plates in a display device, the hinge comprising:
a soft plate member that is bendable while connecting first and second plates;
a plurality of ribs formed at regular intervals at both sides of the soft plate member;
a link means connecting the ribs and composed of first and second links which individually rotates with the bending of the soft plate member; and
a fixing mechanism generating a fixing force by spring elasticity to control the rotation angle of the first and second links of the link means,
wherein a folded or unfolded angle of the link means is maintained by a fixing force generated by the fixing mechanism.

### Claim 2 (depends on 1)

The hinge of claim 1, wherein the first and second inks each comprises a hollow cylindrical body in which an internal channel is formed, with both end open and a panel extending from the body and connected to the ribs wherein the panels of the first and second links are connected to two adjacent ribs arranged in the opposite directions, respectively.

### Claim 3 (depends on 2)

The hinge of claim 2, further comprising a shaft pin connected to the fixing mechanism through the first and second links.

### Claim 4 (depends on 1)

The hinge of claim 1, wherein the fixing mechanism comprises:
an operation member having a protrusion on one side thereof which is locked to one side of the second link, fitted on the shaft pin, and disposed between the first and second links; and
an elastic member combined with the first link and generating a force pushing the operation member,
wherein protrusion grooves are formed on one side of the second link to correspond to the protrusion of the operation member.

### Claim 5 (depends on 4)

The hinge of claim 4, wherein two protrusions and two protrusion grooves are symmetrically formed in pairs, respectively.

### Claim 6 (depends on 5)

The hinge of claim 5, wherein the protrusions and the protrusion grooves are formed in a semicircular shape.

### Claim 7 (depends on 1)

The hinge of claim 1, wherein the soft plate member has:
first and second plate portions connected with the first and second plates, respectively; and
a curved portion connected with the first and second plate portions and mounted on the outer side of the hinge.

### Claim 8 (depends on 7)

The hinge of claim 7, wherein the curved portion is formed by connecting a plurality of mounting surfaces where the brackets of the ribs are mounted and the mounting surfaces each have a folding portion formed in the width direction for easy bending.
