Like reference numerals designate like elements throughout the specification. In this disclosure, the term “substantially” includes the meanings of completely, almost completely or to any significant degree under some applications and in accordance with those skilled in the art. The term “connected” includes an electrical connection.
Referring to FIGS. 1 to 3, an apparatus for supporting a display panel according to an exemplary embodiment provides a simple support device that can be rotated based on two rotation shafts while supporting a flexible display panel, irrespective of a distance between the two rotation shafts.
Referring to FIGS. 1 and 2, the apparatus for supporting the display panel includes first and second connecting portions (or first and second connectors) 100 and 300, a spacer 500, a link member 700, and first and second support portions (or first and second supports) 800 and 900.
First, the first and second support portions 800 and 900 support the display panel (not shown) that is foldable or bendable. Referring to FIG. 2, the display panel (not shown) may be placed on the unfolded first and second support portions 800 and 900. The first and second support portions 800 and 900 may be rotated based on first and second rotation shafts 200 and 400, respectively, thereby allowing the display panel (not shown) to be bendable or foldable.
Herein, the first and second rotation shafts 200 and 400 may be placed substantially parallel to each other, as shown in FIG. 1. In this case, the first and second support portions 800 and 900 may have a plate-like shape. The first and second support portions 800 and 900 may have sizes corresponding to that of the display panel that is positioned on them. The first connecting portion 100 is fixedly combined to one side of the first support portion 800. In this case, the first connecting portion 100 is positioned on the first rotation shaft 200.
That is, when the first connecting portion 100 is fixed to one side of the first support portion 800 and the first support portion 800 is then rotated based on the first rotation shaft 200, the first connecting portion 100 may be rotated along with the first support portion 800. In this case, the first connecting portion 100 may be connected to the second connecting portion 300 through the link member 700 to be described later such that it is rotated along with the first support portion 800. The first connecting portion 100 includes a first connecting plate 170, a first penetration member 150, a first coupling protrusion 110, and a first stopper 130.
Referring to FIGS. 1 to 3 and 5, the first connecting plate 170 is placed at one side of the first support portion 800. The first connecting plate 170 is combined to the link member 700 to be described later through the first coupling protrusion 110. The first connecting plate 170 may have a plate-like shape. According to the exemplary embodiment, the first connecting plate 170 has a circular plate-like shape. In this case, the first rotation shaft 200 is placed to cross a center of the first connecting plate 170.
The first stopper 130 is placed on the first connecting plate 170. The first stopper 130 has a semicircular plate-like shape, and is positioned on the first connecting plate 170. When the first connecting plate 170 connected to the first support portion 800 is rotated, the first stopper 130 prevents the first connecting plate 170 from being rotated by more than a predetermined angle.
As shown in FIG. 3, since the first stopper 130 protrudes further than the first connecting plate 170, the first stopper 130 prevents the first support portion 800 from being rotated by more than the predetermined angle. For example, it is assumed that the first support portion 800 is rotated from a position illustrated in FIG. 1 to a position illustrated in FIG. 2, that is, the first support portion 800 is rotated by 90° in a counterclockwise direction based on the first rotation shaft 200.
In this case, the first connecting plate 170 illustrated in FIG. 1 is combined to the link member 700 through the first coupling protrusion 110. Then, as shown in FIG. 2, when the first connecting plate 170 is rotated by a predetermined rotation angle in the counterclockwise direction, the first connecting plate 170 cannot be rotated any further because of the first stopper 130.
That is, as shown in FIG. 2, the first connecting plate 170 cannot be rotated by more than 90° from the original position of the first connecting plate 170 illustrated in FIG. 1. In addition, referring to FIG. 5, the first penetration member 150 is combined under the first connecting plate 170. The first penetration member 150 penetrates the spacer 500 to be described later, and is combined to one side of the first support portion 800.
The first connecting plate 170 may be fixedly combined to the first support portion 800 by the first penetration member 150. The first coupling protrusion 110 is formed on the first connecting plate 170. The first coupling protrusion 110 is combined to the link member 700 such that it is rotatable.
Referring to FIG. 3, the first coupling protrusion 110 is combined to a first coupling hole 710 of the link member 700. In some embodiments, the first coupling protrusion 110 is formed on a predetermined position on the first connecting plate 170.
More specifically, referring to FIG. 1, when the first and second support portions 800 and 900 are folded with respect to each other, the first coupling protrusion 110 is positioned in a first quadrant of the first connecting plate 170. Herein, when the first and second support portions 800 and 900 are folded with respect to each other, the first and second support portions 800 and 900 form an angle of about 0°.
In addition, referring to FIG. 2, when the first and second support portions 800 and 900 are unfolded, the first coupling protrusion 110 is positioned in a second quadrant of the first connecting plate 170. Herein, when the first and second support portions 800 and 900 are unfolded, the first and second support portions 800 and 900 form an angle of about 180°. Herein, quadrants of the first connecting plate 170 represent quadrants that are formed on the first connecting plate 170 by an X axis perpendicular to the first and second rotation shafts 200 and 400 and an Y1 axis perpendicular to the X axis and crossing the center of the first connecting plate 170.
In this case, the X axis is included in a plane that is formed by the first and second rotation shafts 200 and 400. The X and Y1 axes may correspond to the first shaft and the second shaft in the claims. A position of the first coupling protrusion 110 according to rotation of the first and second support portions 800 and 900 will be specifically described later. The second connecting portion 300 is fixedly combined to one side of the second support portion 900.
In this case, the second connecting portion 300 is positioned on the second rotation shaft 400. That is, when the second support portion 900 is rotated based on the second rotation shaft 400, the second connecting portion 300 may be rotated along with the second support portion 900 since it is fixed to one side of the second support portion 900. The second connecting portion 300 includes a second connecting plate 370, a second penetration member 350, a second coupling protrusion 310, and a second stopper 330.
Referring to FIGS. 1 to 3 and 5, the second connecting plate 370 is placed at one side of the second support portion 900. The second connecting plate 370 is combined to the link member 700 to be described later through the second coupling protrusion 310. The second connecting plate 370 may have a plate-like shape.
The second connecting plate 370 may have a circular plate-like shape. In this case, the second rotation shaft 400 is placed to cross a center of the second connecting plate 370. The second stopper 330 is placed on the second connecting plate 370.
The second stopper 330 has a semicircular plate-like shape, and is positioned on the second connecting plate 370. In this case, when the second connecting plate 370 connected to the second support portion 900 is rotated, the second stopper 330 prevents the second connecting plate 370 from being rotated by more than a predetermined angle.
As shown in FIG. 3, since the second stopper 330 protrudes further than the second connecting plate 370, the second stopper 330 prevents the second connecting plate 370 from being rotated by more than the predetermined angle. For example, it is assumed that the second support portion 900 is rotated from a position illustrated in FIG. 1 to a position illustrated in FIG. 2, that is, the second support portion 900 is rotated by 90° in the clockwise direction based on the second rotation shaft 400.
In this case, the second connecting plate 370 illustrated in FIG. 1 is combined to the link member 700 through the second coupling protrusion 310. Then, as shown in FIG. 2, when the second connecting plate 370 is rotated by a predetermined rotation angle in the clockwise direction, the second connecting plate 370 cannot be rotated any further by the second stopper 330.
That is, as shown in FIG. 2, the second connecting plate 370 cannot be rotated by more than 90° from the original position of the second connecting plate 370 illustrated in FIG. 1. In addition, referring to FIG. 5, the second penetration member 350 is combined under the second connecting plate 370. The second penetration member 350 penetrates the spacer 500 to be described later, and is combined to one side of the second support portion 900.
The second connecting plate 370 may be fixedly combined to the second support portion 900 by the second penetration member 350. The second coupling protrusion 310 is formed on the second connecting plate 370. The second coupling protrusion 310 is combined to the link member 700 such that it is rotatable. Referring to FIG. 3, the second coupling protrusion 310 is combined to a second coupling hole 730 of the link member 700.
Similar to the first coupling protrusion 110 described above, the second coupling protrusion 310 is formed at a predetermined position on the second connecting plate 370. Referring to FIG. 1, when the first and second support portions 800 and 900 are folded with respect to each other, the second coupling protrusion 310 is positioned in a fourth quadrant of the second connecting plate 370.
In addition, referring to FIG. 2, when the first and second support portions 800 and 900 are unfolded with respect to each other, the second coupling protrusion 310 is positioned in a third quadrant of the second connecting plate 370. Herein, quadrants of the second connecting plate 370 represents the quadrants that are formed on the second connecting plate 370 by the X axis and an Y2 axis perpendicular to the X axis and crossing the center of the second connecting plate 370.
In this case, the Y2 axis may correspond to a third axis in the claims. A position of the second coupling protrusion 310 according to the rotation of the first and second support portions 800 and 900 will be specifically described later. Referring to FIG. 5, the first and second connecting plates 170 and 370 are placed to form the same plane at the sides of the first and second support portions 800 and 900.
As shown in FIG. 5, the first and second connecting plates 170 and 370 form the same plane, and the link member 700 is placed on the first and second connecting plates 170 and 370. Referring to FIGS. 10 and 11, first and second magnetic members 190 and 390 may be placed on the first and second stopper 130 and 330.
In addition, a third magnetic member 750 may be placed on the link member 700. Referring to FIG. 10, when the first stopper 130 and the link member 700 contact each other, the first magnetic member 190 is placed such that it contacts the third magnetic member 750 positioned on the link member 700 and such that it forms the same plane as one side of the first stopper 130.
When the first and second support portions 800 and 900 are unfolded with respect to each other, the first and third magnetic members 190 and 750 contact each other. Similarly, when the second stopper 330 and the link member 700 contact each other, the second magnetic member 390 is placed such that it forms the same plane as one side of the second stopper 330 and such that it contacts the third magnetic member 750 positioned on the link member 700.
When the first and second support portions 800 and 900 are folded with respect to each other, as shown in FIG. 10, the second and third magnetic members 390 and 750 contact each other. The third magnetic member 750 is placed on the link member 700. As described above, the third magnetic member 750 may contact the first or second magnetic members 190 and 390.
As such, the first and second support portions 800 and 900 having reached desired positions may be identified by the contacts between the first and second magnetic members 190 and 390 and the third magnetic member 750 contact each other when the first and second support portions 800 and 900 are rotated to be folded or unfolded.
Alternatively, since the magnetic members are combined to each other by a magnetic force in their respective positions, the first and second support portions 800 and 900 are prevented from being rotated contrary to a user's intention.
Referring back to FIGS. 1 to 3, the first and second connecting plates 170 and 370 are combined to the link member 700 such that they are rotatable. In this case, the link member 700 may be a bar-shaped member. As described above, when the first and second connecting plates 170 and 370 are rotated to reach the specific positions, sides of the bar-shaped link member 700 may make surface contact with the first or second stopper 130 and 330. In addition, the first and second coupling holes 710 and 730 are formed in opposite end portions of the link member 700, respectively. The first and second coupling protrusions 110 and 310 formed in the first and second connecting plates 170 and 370 described above are inserted into the first and second coupling holes 710 and 730, respectively.
Referring to FIGS. 4 and 5, the spacer 500 is placed between the first and second connecting portions 100 and 300 and the first and second support portions 800 and 900. The spacer 500 may maintain a distance L between the first and second rotation shafts 200 and 400 to be constant. As shown in FIG. 5, as the first and second connecting portions 100 and 300 penetrate the spacer 500, an interval between the first and second rotation shafts 200 and 400 is maintained constant. More specifically, first and second penetration holes 510 and 530 are formed in the spacer 500.
The first penetration member 150 of the first connecting portion 100 and the second penetration member 350 of the second connecting portion 300 penetrate the first and second penetration holes 510 and 530, respectively. In this case, since the first and second penetration members 150 and 350 are respectively parallel to the first and second rotation shafts 200 and 400, respectively, the distance L between the first and second rotation shafts 200 and 400 may be maintained constant when the first and second support portions 800 and 900 are rotated.
The first and second support portions 800 and 900 may be rotated by the same angle based on the plane that is formed by the first and second rotation shafts 200 and 400. Herein, the plane formed by the first and second rotation shafts 200 and 400 represent a plane including the first and second rotation shafts 200 and 400. That is, when the first support portion 800 is rotated by the predetermined angle based on the plane, the second support portion 900 may also be simultaneously rotated by the same angle based on the plane.
The first and second support portions 800 and 900 may be rotated by an angle of 0° to 180°. More specifically, the first and second support portions 800 and 900 illustrated in FIG. 1 form an angle of about 0° with respect to each other. The first and second support portions 800 and 900 illustrated in FIG. 2 form an angle of about 180° . In this case, the first and second support portions 800 and 900 start rotating at the position illustrated in FIG. 1.
As the angle formed by the first and second support portions 800 and 900 increases, the first and second support portions 800 and 900 may be rotated to the position illustrated in FIG. 2 where the angle formed by the first and second support portions 800 and 900 is 180°. As a result, the first and second support portions 800 and 900 may be upwardly rotated based on the plane that is formed by the first and second rotation shafts 200 and 400 described above.
Now, an operation of the first and second connecting portions 100 and 300 and the link member 700 of the apparatus for supporting the display panel according to the exemplary embodiment will be described with reference to FIGS. 6 to 9. In some embodiments, based on the plane including the first and second rotation shafts 200 and 400, one of the first and second coupling protrusions 110 and 310 is positioned in an upper area of th plane, while the other is positioned in a lower area of the plane.
One of the first and second coupling protrusions 110 and 310 is positioned in the upper area of the plane, while the other is positioned in the lower area of the plane. Alternatively, if the first coupling protrusion 110 is positioned in the lower area of the plane, the second coupling protrusion 310 is positioned in the upper area of the plane.
First, a case in which the first coupling protrusion 110 is positioned in the upper area of the plane and the second coupling protrusion 310 is positioned in the lower area of the plane will be described with reference to FIGS. 6 and 7. Referring to FIG. 6, when the first and second support portions 800 and 900 are folded with respect to each other, the first coupling protrusion 110 is placed in a first quadrant of the first connecting plate 170, that is, in the upper area of the plane.
In this case, the second coupling protrusion 310 is positioned in a fourth quadrant of the second connecting plate 370, that is, in the lower area of the plane.
