The support groove 142c2 may be formed at a position corresponding to a portion of the length of the lever portion 102a of the elastic member 102. The friction pad 142c1 may be formed in the support groove 142c2. The friction pad 142c1 may be formed to protrude from the support groove 142c2, and its surface may be smoothly polished.

When the wings (141, 142) are pivotably coupled to the wing brackets (131, 132), a gap may be formed between the pivot axes (141p, 142p) of the wings (141, 142) and the wing holders (131b, 132b) of the wing brackets (131, 132). there is. In the mechanism where the moving block 134 transmits force to the flip frame 133 and the wings 141 and 142 bend the display panel 110, the gap between components causes the bending of the display panel 110 to temporarily stop. You can do it. The wings 141 and 142 may receive force from the elastic member 102 toward the front of the display device 100. Accordingly, bending of the display panel 110 can be implemented continuously. Additionally, power consumption of the motor 137 for bending the display panel 110 can be reduced.

In addition, by screwing the sliding block 134b (see FIG. 6) and the lead screw 135, a clearance for the sliding block 134b to move on the lead screw 135 may be formed. The elastic member 102 pushes the wings 141 and 142 to bring the sliding block 134b into close contact with the lead screw 135 in one direction, thereby enabling continuous bending of the display panel 110. Additionally, when the display panel 110 is flat, when the rotational force of the motor 137 and the lead screw 135 is released, the flatness of the display panel 110 may change. According to this embodiment, the display panel 110 may be maintained in a flat state and/or the display panel 110 may be maintained in a state curved at a predetermined curvature.

Referring to FIG. 14, the flip frame 133 may include holes 133H1 and 133H2. The holes 133H1 and 133H2 may be located adjacent to ends of the first frame 133a and/or the second frame 133b of the flip frame 133. The holes 133H1 and 133H2 may be long holes 133H1 and 133H2 having a major axis and a minor axis. The long axes of the holes 133H1 and 133H2 may be parallel to the longitudinal direction of the frame 133. The short axis of the holes 133H1 and 133H2 may intersect the longitudinal direction of the frame 133.

15 to 17, the pivot pin 133c is inserted into the holes 133H1 and 133H2 of the flip frame 133, and the moving block 134 can move on the lead screw 135. As the moving block 134 moves on the lead screw 135, the display panel 110 can change from a flat state (see FIG. 15) to a curved state (see FIG. 16) and to a constant curvature (see FIG. 17). .

When the display panel 110 begins to curve from a flat state or when the display panel 110 is curved to a predetermined curvature and then becomes flat as the curvature radius becomes larger than the predetermined curvature radius, the moving block 134 The direction of movement may change. That is, at the starting and ending points of the moving block 134, the display panel 110 may be flat or curved with a predetermined curvature.

When the moving block changes the direction of movement at the starting and/or ending point, the direction in which the pivot pin 133c applies force to the holes 133H1 and 133H2 of the flip frame 133 may change. As the pivot pin 133c changes the direction in which it applies force to the holes 133H1 and 133H2 of the flip frame 133, the display panel is moved by the gap between the pivot pin 133c and the holes 133H1 and 133H2 of the flip frame 133. Continuity may be broken by changes in the curvature of (110).

18 and 19, the long axes of the holes 133H1 and 133H2 of the flip frame 133 may form an angle (theta) with respect to the longitudinal direction of the flip frame 133. For example, the angle (theta) is a moving block ( 134) may correspond to the angle (theta) formed by the starting or ending point.

As the holes 133H1 and 133H2 of the flip frame 133 approach the starting point or end point of the moving block 134, the long axes of the holes 133H1 and 133H2 become the pivot axes 141p of the wings 141 and 142 of the moving block 134. It can be parallel to the reference line connecting 142p). When the pivot pin 133c changes its direction of movement, the direction of movement of the pivot pin 133c may be aligned with the minor axis direction of the holes 133H1 and 133H2 of the flip frame 133.

At the moment when the pivot pin (133c) changes its moving direction, when the moving direction of the pivot pin (133c) is aligned with the short axis of the holes (133H1, 133H2) of the flip frame (133), the pivot pin (133c) and the flip frame (133) The gap formed between the holes 133H1 and 133H2 can be minimized. Accordingly, the pivot pin 133c can continuously transmit power or force to the flip frame 133 as the moving block 134 moves and/or changes direction.
