An object to be solved is to provide a flexible display device capable of improving user convenience by preventing sagging.

BACKGROUND OF THE INVENTION [0002] Video display devices, which implement various information on a screen, are a core technology in the information and communication era, and are developing toward thinner, lighter, portable and high-performance. Accordingly, an organic light emitting display displaying an image by controlling the amount of light emitted from an organic light emitting layer as a flat panel display device capable of reducing the weight and volume, which are disadvantages of a cathode ray tube (CRT), is in the spotlight.

In the organic light emitting display device, a plurality of pixels are arranged in a matrix form to display an image. Here, each pixel includes a light emitting element and a pixel driving circuit composed of a plurality of transistors that independently drive the light emitting element.

Since such an organic light emitting display device uses a self-emitting organic light emitting element, it does not require a separate light source, and since a spherical shape of an ultra-thin display device is possible, recently, an organic light emitting element is used and a touch electrode array is inside a light emitting cell. Research on a flexible display device of an in-cell touch structure including a is being actively conducted.

At least one of the first protrusion and the second protrusion may include a magnet, so that the first and second protrusions may be joined by the magnet. In this case, heights from the first protrusion and the second protrusion to the display panel are equal to heights from the first and second supports to the display panel.

The first and second supports may further include curved portions on rear surfaces thereof, and the curvature of the curved portion has a value less than a critical curvature, which is a maximum curvature that is not damaged even when the flexible display area is folded.

The flexible display device according to the present invention has a structure in which the flexible display area is folded twice, once on the inner surface and once on the rear surface, and at this time, the first and second supports are formed in a structure in which the first and second supports are in vertical contact, thereby providing high portability. can have

In addition, since the first and second supports of the flexible display device according to the present invention include bent parts, a feeling of grip is improved when a user grips the support parts in a flat state, and the bent parts form a flexible display area. When folded, it prevents folding with a curvature greater than a threshold value.

In addition, the flexible display device according to the present invention has a structure in which the flexible display area moves together while one support part moves in the direction of the other support part. That is, the flexible display device according to the present invention can be folded in a sliding method, in which the display panel is folded by pushing one supporter toward another supporter, rather than the conventional folding method.

In the flexible display device according to the present invention, since the height from the lower end of the protruding part to the display panel is the same as the height from the lower end of the support part to the display panel, when the display panel is in a flat state, the flexible display area has the first and second areas. Supported by the plate and the first and second protrusions, the flexible display area does not move downward even when a user applies pressure to the flexible display area through a touch or the like. At this time, since at least one of the bent parts is formed as a magnet, an optimal bonding force between the bent parts is secured, and the first and second plates can be protruded only by contacting the bent parts without a separate operation.

Referring back to FIG. 1A , the first supporter 1000a is attached to the rear surface of the first fixed display area 100a, and the second supporter 1000b is attached to the rear surface of the second fixed display area 100c. Located. The first support part 1000a and the second support part 1000b are attached to the rear surfaces of the first and second fixed display areas 100a and 100c to fix the first and second fixed display areas 100a and 100c. The first and second fixed display areas 100a and 100c have flat characteristics.

In this case, the first fixed display area 100a, the first supporter 1000a, and the second fixed display area 100c may be bonded together using an adhesive (not shown), but is not necessarily limited thereto.

Referring also to FIG. 1B , in the flexible display device according to the present invention, when the display panel is unfolded in a flat state, it protrudes from the first support part 1000a and the second support part 1000b to form the flexible display area. A third support part 1010 supporting the display panel 100 is included on the rear surface of 100b. The third support portion 1010 includes a first plate 1010a protruding from the first support portion 1000a side and a second plate 1010b protruding from the second support portion 1000b side.

When the display panel 100 is unfolded, the first plate 1010a protrudes from the side of the first support part 1000a to an intermediate point of the flexible display area 100b. In addition, when the display panel 100 is unfolded, the second plate 1010b protrudes along with the first plate 1010a from the second support 1000b and contacts the first plate 1010a.

In other words, in the third support part 1010, the first plate 1010a and the second plate 1010b contact each other at the midpoint of the flexible display area 100b, and the flexible display area 100b moves regardless of the user's intention. serves to prevent

In this case, the third support part 1010 is preferably formed of metal or high-rigidity plastic to prevent the flexible display area 100b from moving regardless of the user's intention.

At this time, the first plate 1010a includes the first protrusion 1011a. The first protrusion 1011a is positioned at a point in contact with the first plate 1010a and the second plate 1010b when the display panel 100 is unfolded in a flat state. In this case, the first protrusion 1011a may have a plate shape disposed vertically with the first plate 1010a below the first plate 1010a, but is not necessarily limited thereto.

Similarly, the second plate 1010b includes the second protrusion 1011b. The second protrusion 1011b is positioned at a point where the second plate 1010b contacts the first plate 1010b when the display panel 100 is unfolded in a flat state. At this time, the second protrusion 1011b may have a plate shape vertically disposed with the second plate 1010b below the second plate 1010b, but is not necessarily limited thereto.

Accordingly, when the display panel 100 is unfolded in a flat state, the first protrusion 1011a and the second protrusion 1011b contact each other at an intermediate point of the flexible display area 100b.

When the display panel 100 is unfolded in a flat state, the first and second protrusions 1011a and 1011b are pressed by a force applied to the display panel 100 in a vertical direction by a user's touch or the like. It serves to prevent slipping or falling down. To this end, lower ends of the first and second protrusions 1011a and 1011b are positioned on the same line as lower ends of the first and second support parts 1000a and 1000b. A detailed description of the feature will be given later.

The first support part 1000a includes a first control pin 1021a for inserting the first plate 1010a into the first support part 1000a or protruding the first plate 1010a out of the first support part 1000a. ) may be further included.

Similarly, the second support portion 1000b includes a second control pin (for inserting the second plate 1010b into the second support portion 1000b or protruding the second plate 1010b out of the second support portion 1000b) 1021b) may be further included.

Referring to FIG. 1C , when the flexible display panel 100 is folded in a folded state, the first support part 1000a and the second support part 1000b are vertically positioned with each other in a vertical direction. As an example, FIG. 1C shows a shape in which the first support part 1000a is located above the second support part 1000b, but the first support part 100a can be freely moved according to the user's folding shape. 1000b), or vice versa.

3 is a schematic diagram illustrating a process of folding the flexible display device according to the present invention from a flat state to a folded state and an internal structure of the flexible display device according to the present invention.

As mentioned above, the lower ends of the first and second protrusions 1011a and 1011b are positioned on the same line as the lower ends of the first and second support parts 1000a and 1000b. 3(a), the height from the first and second protrusions 1011a and 1011b to the display panel 100 and the height from the first and second support portions 1000a and 1000b The height up to the display panel 100 has the same value (h). Therefore, when the display panel 100 is in a flat state, the center of the flexible display area 100b of the display panel 100 is formed by the first and second plates 1010a and 1010b and the first and second protrusions 1011a and 1011b. , and even if a user applies pressure to the flexible display area 100b by touch or the like, the flexible display area 100b does not move downward.

At this time, at least one of the first and second protrusions 1011a and 1011b may include a magnet (not shown). At this time, the protruding portion that does not include a magnet may be formed to include a material that adheres to a magnet, such as Fe. In addition, both the first and second protrusions 1011a and 1011b may be formed of magnets, and the contact surfaces of the first and second protrusions 1011a and 1011b may have different poles. If at least one of the first and second protrusions 1011a and 1011b includes a magnet, the first and second protrusions 1011a and 1011b are joined by the magnet when the display panel 100 is in a flat state. The flexible display area 100b is supported. At this time, the magnetic force between the first and second protrusions 1011a and 1011b is sufficient to support the flexible display area 100b, and is also sufficient for the user to separate the first and second protrusions 1011a and 1011b again. Since a large force is not required, an optimal bonding force between the first and second protrusions 1011a and 1011b can be provided.

As shown in (b) of FIG. 3 , the second support 1000b may move below the first support 1000a for folding of the flexible display device. When the second support part 1000b moves below the first support part 1000a in this way, the display panel 100 to which the second support part 1000b and the second fixed display area 100c are bonded together also moves to the second support part ( 1000b) moves in the downward direction of the first support part 1000a. In particular, the flexible display area 100b of the display panel 100 moves in the lateral direction of the first support part 100a, and accordingly, the flexible display area 100b is attached to the first plate 1010a by the first support part 1000a. exerts a directional force. Accordingly, the first plate 1010a is directly inserted into the first support part 1000a without using the first adjusting pin 1021a. At this time, the second plate 1010b is still in a state of protruding out of the second support part 1000b, and force is applied directly to the second plate 1010b or by using the second adjusting pin 1021b to remove the second plate ( 1010b) may be inserted into the second support part 1000b.

Similarly, although not shown in FIG. 3 , the first support part 1000a may move below the second support part 1000b. Then, since the first support part 1000a and the first fixed display area 100a are bonded together, the display panel 100 moves in a downward direction of the second support part 1000b along the first support part 1000a. Accordingly, the flexible display area 100b of the display panel 100 moves in the lateral direction of the second support part 1000b, and accordingly, the flexible display area 100b moves in the lateral direction of the second support part 1000b. A force in the direction of the second support portion 1000b is applied to the second plate 1010b. As a result, the second plate 1010b is inserted into the second support part 1000b without using the second adjusting pin 1021b. At this time, the first plate 1010a is still in a state of protruding out of the first support part 1000a, and force is applied directly to the first plate 1010a or by using the first control pin 1021a, the first plate ( 1010a) may be inserted into the first support part 1000a.

When folding is completed, the flexible display device according to the present invention is folded in a form as shown in FIG. 3(c). This is explained in detail below.

The first support part 1000a and the second support part 1000b may be positioned to vertically contact each other. For example, as shown in (c) of FIG. 3 , the first support part 1000a may be positioned above the second support part 1000b. In this case, the flexible display area 100b is an area from a side surface of the upper support portion of the first support portion 1000a and the second support portion 1000b to a space between the first support portion 1000a and the second support portion 1000b. located in That is, when the first support part 1000a is positioned above the second support part 1000b, the flexible display area 100b is formed on the side surface of the first support part 100a and between the first support part 1000a and the second support part 1000b. located in the space between At this time, the first support portion 1000a includes a first bent portion 1030a on its rear surface. The first curved portion 1030a is curved to have a curvature less than a critical curvature, which is the maximum curvature that the flexible display area 100b can have without being damaged when the display panel 100 is folded. The portion of the flexible display area 100b located between the first and second support portions 1000a and 1000b is located on the curved portion of the first curved portion 1030a and has the same curvature as the first curved portion 1030a. It is folded to have a curvature.

In the flexible display device according to the present invention, the second support 1000b may be positioned above the first support 1000a in a direction opposite to that of FIG. 3(c). In this case, the flexible display area is located on the side of the second support 1000b and in a space between the second support 1000b and the first support 1000a. At this time, the second support portion 1000b includes a second bent portion 1030b on its rear surface. The second curved portion 1030b is curved to have the same curvature as the first curved portion 1030a. The portion of the flexible display area 100b positioned between the second support portion 1000b and the first support portion 1000a is located on the curved portion of the second curved portion 1030b and has the same curvature as the second curved portion 1030b. It is folded to have a curvature.

The first and second curved portions 1030a and 1030b are arranged so that the curvature when the flexible display area 100b is folded does not exceed the curvature of the first and second curved portions 1030a and 1030b. It plays a role in controlling the curvature of Therefore, the flexible display area 100b is folded to have a curvature equal to or less than the curvature of the first and second curved portions 1030a and 1030b, so that the stress applied to the flexible display area 100b is maintained below a threshold value, thereby forming the flexible display area. The damage of (100b) is prevented.

Meanwhile, as shown in (c) of FIG. 3 , when the flexible display panel 100 is folded into a folded state, the first plate 1010a is inserted into the first support 1000a, and the second plate ( 1010b) is inserted into the second support part 1000b. In this case, the first protrusion 1011a is positioned to come into contact with the side surface of the first support part 1000a, and the second protrusion 1011b is positioned to come into contact with the side surface of the second support part 1000b.

The flexible display device according to the present invention has a structure in which the flexible display area 100b is folded twice in total, once on the inner surface and once on the rear surface by being folded in the shape shown in (c) of FIG. 3 . Since the first and second support portions 1000a and 1000b are formed in a structure in which they contact each other vertically, high portability can be achieved.

In addition, the first and second support portions 1000a and 1000b of the flexible display device according to the present invention include the first and second curved portions 1030a and 1030b, so that the user can enjoy the first and second support portions in a flat state. When gripping the support portions 1000a and 1000b, a feeling of grip is improved.

Further, the flexible display device according to the present invention has a structure in which, for example, the flexible display area 100b moves along with the second support 1000b while moving in the direction of the first support 1000a. That is, the flexible display device according to the present invention can be folded in a sliding method, in which the display panel is folded by pushing one supporter toward another supporter, rather than the conventional folding method.

The flexible display device according to the present invention may further include a driving circuit 600 and a battery 700 inside the first support part 1000a and the second support part 1000b. At this time, the driving circuit 600 is accommodated in one of the first support part 1000a and the second support part 1000b, and the battery 700 is accommodated in the other support part, so that the driving circuit ( 600) and battery 700 are not located. Accordingly, the flexible display area 100b has a feature that can be freely folded without being affected by the driving circuit 600 and the battery 700 .

4 is a schematic diagram for explaining a process from a folded state to a flat state of the flexible display device according to the present invention. Since reference numerals in FIG. 4 are exactly the same as those in FIG. 3 , description will be made with reference to reference numerals in FIG. 3 .

First, in the folded state shown in FIG. 4(a), side surfaces of the first support part 1000a and the second support part 1000b in the direction of the flexible display area 100b are brought into contact with each other as shown in FIG. 4(b). . Referring to (b) of FIG. 4, as mentioned above, the first protrusion 1011a is in contact with the side surface of the first support part 1000a, and the second protrusion 1011b is in contact with the side surface of the second support part 1000b. are touching In addition, at least one of the first protrusion 1011a and the second protrusion 1011b includes a magnet. The first and second protrusions 1011a and 1011b are bonded to each other by the magnetic force of the magnet. In this state, when the first support part 1000a and the second support part 1000b are moved in opposite directions so that the display panel 100 is in a flat state as shown in FIG. The first and second plates 1010a and 1010b protrude to the middle of the flexible display area 100b by the first and second protrusions 1011a and 1011b. Accordingly, the flexible display area 100b of the display panel 100 is supported by the third support 1010 including the first and second plates 1010a and 1010b and the first and second protrusions 1011a and 1011b. .

That is, when at least one of the first and second protrusions 1011a and 1011b includes a magnet, the first and second plates 1010a and 1010b are formed on the flexible display area 100b without using the control pins 1021a and 1021b. ) The positions of the first and second plates 1010a and 1010b may be adjusted so as to be located on the rear surface.
