The inner ring wall of the chamber 32, that is, the first side space 321 where the rod 341 is located and the second side space 322 facing away from the rod body 341 are separated by the respective flanges 342. One end of each return spring 35 abuts against the outer wall surface of the corresponding main chamber 31, and the other end abuts against the flange 342 of the corresponding connecting member 34, and each return spring 35 is elastically biased at the corresponding connecting member 34.

The driving unit 4 has a pushing member 41, a first magnetic member 42 disposed on the pushing member 41, a second magnetic member 43 spaced apart from the first magnetic member 42 in a front-rear direction, and a control unit 44.

In detail, the pushing member 41 has a cylinder 411 whose one end is located in the main chamber 31, and a head portion 412 which is radially outwardly extended from one end of the cylinder 411 in the main chamber 31. One end of the cylinder 411 is inserted into the through hole 113 of the intermediate portion 111 of the back plate 11, and the screw cap 114 (see FIG. 1) of the intermediate portion 111 is rotated clockwise, and is screwed to the cylinder 411 until it is screwed, so that the column The body 411 is firmly fixed to the through hole 113. The first magnetic member 42 is disposed on the head portion 412, and the peripheral wall of the head portion 412 abuts against the inner annular wall of the main chamber 31, that is, the head portion 412 is partitioned into a first main space 311 facing away from the cylinder 411 and A second main space 312 where the cylinder 411 is located. The main chamber 31 has two flow holes 313, and the second main space 312 of the main chamber 31 communicates with the two second side spaces 322 of the two side chambers 32 through the two flow holes 313. The first magnetic member 42 and the second magnetic member 43 are both located in the first main space 311 of the main chamber 31. One side of the control unit 44 exposes the main chamber 31 for operation and pressing, and the second magnetic member 43 is disposed in the first main space 311 of the main chamber 31 and is away from the display device 1 from the first magnetic member 42. The control unit 44 is configured to control the second magnetic member 43 to change the magnetic pole. In this embodiment, the first magnetic member 42 and the second magnetic member 43 are both electromagnets, but the first magnetic member 42 may also be a permanent magnet.

The mode of operation of the display device of this embodiment will be described below.

Referring to FIGS. 2, 3 and 4, when the display device 1 is in a planar state, the gas pressure in the second main space 312 of the main chamber 31 and the second side space 322 of the side chamber 32 is maintained at one atmosphere. And the magnetic pole of the first magnetic member 42 is at the S pole.

When the user wants to adjust the display device 1 from the planar state to the curved state, first, pressing the control unit 44 to drive the second magnetic field with current. The magnetic property of the member 43 is extremely N pole. The second magnetic member 43 and the first magnetic member 42 generate a magnetic force that is attracted by the opposite pole, and the magnetic force pushes the head portion 412 of the pushing member 41 to move toward the adjacent control unit 44, so that the space of the second main space 312 of the main chamber 31 is made. The gas pressure is increased as the second main space 312 of the main chamber 31 and the second side space 322 of the side chamber 32 become smaller. Then, the external atmospheric pressure is greater than the gas pressure of the second main space 312 and the second side space 322, and the external atmospheric pressure respectively pushes the two rods 341 to move toward the main chamber 31, while the two return springs 35 are compressed, and the second The gas in one side space 321 is pushed into the second side space 322, and the magnetic force, the gas pressure in the second main space 312 and the second side space 322, the elastic force of the two return springs 35, and the external atmospheric pressure are all reached. After the balance, the second magnetic member 43 stops moving. At this time, the two rod bodies 341 and the column body 411 of the display device 1 are displaced rearward, and the displacement amount of the rearward displacement of the intermediate portion 111 is greater than the displacement amount of the rear side displacement of the two side portions 112. In a curved state, as shown in Figures 5 and 6.

When the user wants to adjust the display device 1 from the curved state to the planar state again, pressing the control unit 44 again changes the period of the current to drive the magnetic pole of the second magnetic member 43 to change to the S pole, and the first magnetic member 42 The magnetic pole remains at the S pole, and the second magnetic member 43 and the first magnetic member 42 generate a magnetic force repelled by the same pole, and the magnetic force pushes the head portion 412 of the pushing member 41 to move away from the control unit 44. The space of the second main space 312 of the main chamber 31 is made smaller, and the gas pressures of the second main space 312 and the second side space 322 become larger. Then, when the gas pressure in the second main space 312 and the second side space 322 is greater than the external atmospheric pressure, the two rods 341 are pushed to move toward the corresponding two side portions 112, and the gas of the second side space 322 is pushed into the gas. The first side space 321 , when the magnetic force, the gas pressure in the second main space 312 and the second side space 322, the elastic force of the two return springs 35, and the external atmospheric pressure are balanced, the second magnetic The member 43 stops moving, and the two rods 341 and the cylinder 411 are displaced forward. At this time, the two side portions 112 and the intermediate portion 111 of the display device 1 are displaced forward to switch from the curved state to the planar state, as shown in FIG. 2, FIG. 3 and FIG. 4 is shown.

In the case of power failure, the current cannot be driven to drive the second magnetic member 43 to generate a magnetic pole, so that no magnetic force is generated. At this time, as shown in FIG. 5 and FIG. 6, if the display device 1 is in a bent state before the power is turned off, the two rod bodies 341 are slowly pushed outward by the elastic restoring force of the two return springs 35, and The gas pressure in the second main space 312 of the main chamber 31 and the second side space 322 of the side chamber 32 and the atmospheric pressure of the outside are balanced, and the cylinder 411 is stretched outward to return the display device 1 to the plane. The state is shown in Figures 2, 3 and 4. If the display device 1 is in a planar state before the power is turned off, the elastic force of the two return springs 35, the gas pressure of the second main space 312 and the second side space 322, and the atmospheric pressure of the outside world are balanced to make the display The device 1 remains in a planar state. That is to say, the display device 1 can automatically return to the planar state when it is idle, so as to prevent the display device 1 from being in a bent state when idle, possibly accelerating the aging of the panel module and the backboard 11 of the display device 1 and weakening the display device 1 The curvature in the curved state.

On the other hand, when the two connection units 33 respectively omit the two return springs 35, the display unit 1 in a curved state can be returned to the planar state by pressing the control unit 44 again.

In addition, the user can also adjust the current flowing into the second magnetic member 43. The flow rate, which in turn changes the magnitude of the magnetic force, thereby changing the degree of curvature curvature, controls the curvature of the display device 1 in a curved state.

In summary, by pressing the control unit 44, the period of the current is changed to drive the magnetic pole of the second magnetic member 43 to be changed, and the first magnetic member 42 generates a magnetic force that is repelled by the same pole and a magnetic force that is attracted by the opposite pole. The magnetic force pushes the pusher 41 and the intermediate portion 111 in the front-rear direction to change the display device 1 between the curved state and the planar state, so that the object of the present invention can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
