## Abstract

A display device includes a flexible display and a support frame. The flexible display includes a first portion, a second portion, and a third portion there between. The support frame includes a first display support supporting the first portion, a second display support supporting the second portion, and a third display support supporting the third portion. The third display support is connected to the first display support and the second display support. The first display support and the second display support are rotatably connected between a configuration for maintaining the flexible display in a closed position and a configuration for maintaining the flexible display in an open position. The third display support includes a panel movable according to the rotation of the first display support and the second display support, such that the panel contacts the third portion of the flexible display in an open position of the flexible display.

## Claims

### Claim 1

A display device comprising:
a flexible display comprising a first portion, a second portion, and a third portion between the first portion and the second portion;
a first display support supporting the first portion of the flexible display;
a second display support supporting the second portion of the flexible display; and
a flexible support continuously supporting the third portion of the flexible display in a closed position and an open position;
wherein the flexible support comprises a plurality of rods supporting the third portion of the flexible display,
wherein the first display support and the second display support are rotatably connected to a first hinge and a second hinge, respectively,
wherein when the flexible display is in the open position, the flexible display is contacted and supported by the first display support, the second display support and the flexible support, and
wherein, when the flexible display is in the open position, the plurality of rods are positioned under a surface of the third portion of the flexible display and over both the first hinge and the second hinge.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the flexible support facilitates a curved portion of the flexible display in the closed position.

### Claim 3 (depends on 1)

The display device of claim 1, wherein both end portions of the flexible support are rolled with the first hinge and the second hinge in the open position such that the flexible support is stretchable to support the third portion of the flexible display.

### Claim 4 (depends on 1)

The display device of claim 1, further comprising:
a spring tape supporting the plurality of rods when the flexible display is in the open position, and
wherein an end portion of the spring tape is connected to at least one of the first display support and the second display support.

### Claim 5 (depends on 4)

The display device of claim 4, wherein when the flexible display is in the open position, a gap is created between the plurality of rods and the spring tape.
