Abstract

A flexible display device includes a flexible display panel, a flexible printed circuit board extending from the display panel, an integrated circuit chip that is mounted on at least one surface of the flexible printed circuit board and is configured to drive the display panel, and a protection member attached to a rear surface of the display panel. When the flexible printed circuit board is flexed to be partially positioned on the rear surface of the display panel, the protection member is positioned between the display panel and the integrated circuit chip. The flexible display device prevents the integrated circuit chip stacked with the display panel from making direct contact with the display panel using the protection member. Thus, even if the display device is deformed into, for example, a flexed or rolled state, it is possible to prevent the display panel from being damaged.

Claims (18)

1. A flexible display device comprising:

a flexible display panel;

an integrated circuit chip;

a flexible printed circuit board extending from the flexible display panel and provided to connect the integrated circuit chip and the flexible display panel, the integrated circuit chip mounted on a first surface of the flexible printed circuit board and is configured to drive the flexible display panel;

a bracket attached, on a first side of the bracket, to a rear surface of the flexible display panel and configured to enclose at least a part of the flexible display panel including a periphery of the flexible display panel; and

an accommodation space that accommodates the integrated circuit chip mounted on the flexible printed circuit board for preventing the integrated circuit chip, including its top and surrounding surfaces, from coining into direct contact with other elements,

wherein the accommodation space is formed on a second side of the bracket opposite to the first side,

wherein the integrated circuit chip is accommodated in the accommodation space at a position between a portion of the flexible printed circuit board and the bracket,

wherein, the integrated circuit chip is disposed below the flexible display panel and the bracket, and at least part of the flexible printed circuit board is disposed below the bracket, and

wherein the flexible printed circuit board includes a circuit pattern formed on the first surface and directly connected to the integrated circuit chip and the flexible display panel.

2. The flexible display device of claim 1 , further comprising:

a main circuit board provided at an end of the flexible printed circuit board,

wherein, when the flexible printed circuit board is partially positioned on a rear surface of the flexible display panel, the main circuit board is disposed to at least partially face the bracket.

3. The flexible display device of claim 2 , wherein at least a part of the main circuit board is accommodated in the accommodation space.

4. The flexible display device of claim 1 , wherein the rear surface of the flexible display panel is disposed to face the first surface of the bracket.

5. The flexible display device of claim 4 , wherein the first surface of the bracket facing the flexible display panel is flat.

6. The flexible display device of claim 5 , further comprising an adhesive layer formed between the flexible display panel and the bracket.

7. The flexible display device of claim 1 , wherein the bracket is provided to enclose the periphery and the rear surface of the flexible display panel.
