Abstract

Disclosed is display device. The display device includes: a flexible display panel; a flexible rear plate which is located in a rear of the display panel, and coupled to the display panel; a flexible inner plate coupled to the rear plate, at between the rear plate and the display panel; a driving module which is coupled to a rear of the rear plate, and has a slider linearly reciprocating; a wing which extends long, has one end coupled to the slider, has the other end coupled to the rear of the rear plate, and has a pivot shaft located adjacent to the one end at between the first end and the other end; and a wing bracket which is adjacent to the pivot shaft and fixed to the rear of the rear plate, coupled to the pivot shaft, wherein the inner plate comprises a plurality of cutting lines which are located between one end and the other end of the wing, and formed by cutting out a front surface of the inner plate, wherein the plurality of cutting lines are elongated in a direction intersecting a longitudinal direction of the wing.

First claim

The invention claimed is:

1 . A display device comprising:
a flexible display panel; a flexible rear plate located at a rear of the display panel and coupled to the display panel; a flexible inner plate coupled to the rear plate between the rear plate and the display panel; a driving module coupled to a rear of the rear plate and including a slider, the slider being configured to reciprocate linearly; a wing, the wing being elongated and including one end coupled to the slider, an other end coupled to the rear of the rear plate, and a pivot shaft located adjacent to the one end between the one end and the other end; and a wing bracket adjacent to the pivot shaft, the wing bracket being fixed to the rear of the rear plate and coupled to the pivot shaft, wherein the inner plate comprises a plurality of cutting lines located between the one end and the other end of the wing and formed by cutting out a front surface of the inner plate, wherein the plurality of cutting lines are elongated in a direction intersecting a longitudinal direction of the wing, wherein the driving module comprises:
a front bracket fixed to the rear of the rear plate;
a rear bracket facing the front bracket; and
a lead screw, the lead screw being elongated from the front bracket toward the rear bracket, and being rotatably coupled to the front bracket or the rear bracket, and
wherein the slider is threaded with the lead screw to perform linear reciprocating motion.

2 . The display device of claim 1 , wherein the display panel comprises:
a left side; and a right side facing the left side,
wherein the wing comprises:
a first wing including the one end coupled to the slider and the other end adjacent to the left side, wherein the other end of the first wing is fixed to the rear of the rear plate; and
a second wing including the one end coupled to the slider and the other end adjacent to the right side, wherein the other end of the second wing is fixed to the rear of the rear plate, and

wherein the plurality of cutting lines comprise:
a plurality of first cutting lines located between the other end of the first wing and the slider; and
a plurality of second cutting lines located between the other end of the second wing and the slider.

3 . The display device of claim 2 , wherein the first plurality of cutting lines are symmetrical with the second plurality of cutting lines with respect to the slider.

4 . The display device of claim 2 , wherein, in the plurality of cutting lines, a cross section of the inner plate forms a quadrangle in a direction intersecting the longitudinal direction.

5 . The display device of claim 2 , wherein, in the plurality of cutting lines, a cross section of the inner plate forms a triangle in a direction intersecting the longitudinal direction.

6 . The display device of claim 2 , wherein, in the plurality of cutting lines, a cross section of the inner plate forms a trapezoid in a direction intersecting the longitudinal direction.

7 . The display device of claim 1 , wherein a thickness of the inner plate is 1.3 to 1.7 times a depth of the cutting line.

8 . The display device of claim 1 , wherein the inner plate further comprises a plurality of cutouts which are spaced apart from each other along an upper side of the inner plate and sequentially formed.

9 . The display device of claim 8 , wherein the inner plate further comprises a plurality of accommodating holes which are spaced apart from each other along a lower side of the inner plate and sequentially formed.

10 . The display device of claim 1 , wherein the driving module further comprises:
a first guide shaft which is parallel to the lead screw, and fixed to the front bracket or the rear bracket; and a second guide shaft which is parallel to the lead screw, is fixed to the front bracket or the rear bracket, and is opposite to the first guide shaft with respect to the lead screw.

11 . The display device of claim 10 , wherein the driving module further comprises a slider guide into which the first guide shaft and the second guide shaft are inserted, and which is movable on the first guide shaft and the second guide shaft, and is fixed to the slider.
