Description

Folder structure for flexible display panel {Foldable structure for flexible display panel}

TECHNICAL FIELD The technical field of the present invention relates to a folder structure, in particular, by using a folding unit to allow folding between two folder object units, and at the same time, when the two folder object units are unfolded, two folder object units are included. It relates to a folder structure implemented so that the top surfaces of the two folder target units are completely flat.

The folder structure allows folding or unfolding of folder target units such as doors, chairs, and beds by using hinges or hinges. In particular, display devices with bent or folded display panels (i.e., flexible display modules) are also available. Allows you to fold or unfold. Such a flexible display device can reproduce an input image on a screen of a display panel on which a plastic OLED is formed. At this time, the plastic OLED is formed on a flexible plastic substrate.

In addition, the flexible display device can implement various designs, has advantages in portability and durability, and can be implemented in various forms such as a bendable display device, a foldable display device, and a rollable display device. In addition, it can be applied not only to mobile devices such as smartphones and tablet PCs, but also to TV (Television), automobile displays, and wearable devices, and thus its application fields are expanding.

Korean Patent Publication No. 10-2018-0036903 (published on April 10, 2018) discloses a foldable display device, wherein a first area, a second area, and a third area between the first area and the second area are defined. A flexible display panel having a flat first state and a second state bent with respect to a central axis extending along the first direction; And a device disposed under the flexible display panel and having a first body and a second body rotatably fastened through a hinge portion, wherein the first body includes a first flatness supporting a first region of the flexible display panel. A portion and a first curved portion extending from the first flat portion and having a curved top surface, and the second body includes a second flat portion supporting a second region of the flexible display panel and a second flat portion And a second curved portion having a shape symmetrical to the first curved portion based on a center line crossing the center of the first and second bodies. According to the disclosed technology, by providing a device having a first body and a second body supporting the flexible display panel, physical durability of the flexible display panel may be improved, and a hinge portion connecting the first body and the second body is provided. By doing so, it is possible to stably maintain the distance between the first body and the second body in response to a change in the state of the flexible display panel. That is, the first body and the second body are interconnected through a hinge part, so that a defined trajectory with one degree of freedom Because it is moved along the line, the flexible display panel is not compressed or stretched, and a stable outer folding operation can be implemented while maintaining a constant length.

Korean Patent Laid-Open Publication No. 10-2016-0087972 (published on July 25, 2016) states that when the foldable display device is folded, the deformation of the flexible display module is reduced as the hinge member operates, and the two axes of the hinge member are 2 Since the flexible display module is folded as the guide lines are moved, the housing can maintain a folding area of a certain length, and thus the flexible display module is disclosed in relation to a foldable display device that can be stably protected by the housing. . According to the disclosed technology, a housing including a first support member, a second support member disposed to be spaced apart from the first support member, and a hinge member connecting the first support member and the second support member; And a flexible display module coupled to the first support member and the second support member, wherein the hinge member includes a rotation unit, a first axis coupled to one surface of the rotation unit, and a second axis coupled to the other surface of the rotation unit. body; And a first guideline facing one surface of the rotating portion of the first body and coupled to the first axis, and a second guideline having a curved shape facing the other surface of the rotating portion of the first body and coupled to the second axis. It characterized in that it comprises a second body including.

In the conventional folder structure as described above, when a folder object unit such as a door, chair, bed, etc. is folded or unfolded using a hinge or a hinge, a space is generated between the two folder object units. There is a disadvantage in that the upper surfaces of the two folder target units are not completely flat when two folder target units are unfolded. In addition, in the conventional folder structure, if a hinge or a hinge is formed on the folder target unit so that no space occurs between the two folder target units, there is a disadvantage that it is difficult to provide another unit on the folder target unit. When a folded or folded display panel (i.e., a flexible display module) is provided on the folder target unit, it is not completely folded when folded, or when it is forcibly folded, the flexible display module is crushed and a line is formed in the folded part to display the screen. There is also a disadvantage in that it does not provide clear picture quality.
