The rail 210 is positioned at a lower portion of the fixing bracket 220 at the rear of the display panel 110 so that the guide rail 211 is positioned at the other end of the supporting portion 221 of the fixing bracket 220 Connected and fixed.

The guide rail 211 is formed to have a length corresponding to one edge of the display panel 110. The guide rail 211 is provided with first and second guide brackets 213a, and 213b.

The guide rail 211 has a substantially U-shaped cross section perpendicular to the longitudinal direction. The guide rail 211 has a first guide portion 211a connected to the other end of the support portion 221 of the fixing bracket 220, A second guide part 211b and a first guide part 211a and a second guide part 211b which are positioned perpendicular to the first guide part 211a and the second guide part 211b in parallel with the guide part 211a, And a third guide portion 211c connecting one end of the second guide portion 211c to the other.

The other ends of the first and second guide portions 211a and 211b are respectively engaged with the other ends of the first and second guide portions 211a and 211b in the direction in which the fourth and fifth guide portions 211d and 211e face each other, And is formed as an opening.

Each of the first and second guide brackets 213a and 213b includes a vertical guide portion 215 formed to face the third guide portion 211c and a guide portion 215 extending from the vertical guide portion 215 to the guide rail 211 And a horizontal guide portion 217 protruding toward the opening portion of the first guide bracket 213a and the second guide bracket 213b is formed on the inner surface of the first and second guide portions 211a and 211b. The first and second guide holes 219a and 219b are inserted and guided at both ends in the longitudinal direction thereof.

The first and second guide brackets 213a and 213b are inserted into the first and second guide holes 219a and 219b of the guide rail 211 while both ends of the vertical guide portion 215 are inserted, And linearly moves along the longitudinal direction of the rail 211.

At this time, as shown in FIG. 3B, the first and second guide brackets 213a and 213b are positioned at the center of the guide rail 211 in the non-use mode.

One end of each of the first and second rotary links 205a and 205b is fixed to the horizontal guide portion 217 of the first and second guide brackets 213a and 213b and the first and second rotary links 205a And 205b are connected to a pair of first and second links 203a and 203b located below the rail 210. [

The pair of first and second links 203a and 203b are each formed to have a length corresponding to one half of the length corresponding to one edge of the display panel 110. The first and second links 203a and 203b Are connected to the motor 201 located at both ends in the longitudinal direction of the display panel 110, and the other ends thereof are positioned so as to face each other.

The first and second guide brackets 213a and 213b positioned at the center of the guide rail 211 and the first and second rotary links 205a and 205b, 2 links 203a and 203b, respectively.

When the first and second links 203a and 203b are positioned perpendicular to the longitudinal direction of the display panel 110, the rotation of the first and second motors 201 is stopped, and as shown in FIG. 3D, The automatic rampable display device 100 according to the embodiment of the present invention realizes the use mode.

At this time, the first and second links 203a and 203b support both edges perpendicular to one edge of the display panel 110 that is opened.

Thus, the rigidity of the display panel 110 can be improved.

Although not shown in the drawing, a winding motor is also mounted on the roller 120 on which the display panel 110 is wound. The winding motor is interlocked with the first and second motors 201, The motor for winding also rotates in accordance with the rotational motion of the first and second motors 201.

Accordingly, in order to implement the mode of use, the first and second motors 201 of the automatic rampable display device 100 according to the embodiment of the present invention are rotated to unfold the display panel 110 from the roller 120 The motor for winding the roller 120 interlocked with the first and second motors 201 is also rotated and the roller 120 is also rotated by the rotation of the winding motor.

As the roller 120 rotates, the circular motion of the first and second links 203a and 203b and the linear motion of the first and second guide brackets 213a and 213b are transmitted to the rail 210 The display panel 110 can be more easily released from the roller 120 in the process of lifting up the display panel 110 while pushing up the fixing bracket 220 upward.
