Description

Display device

The present invention relates to a display device, in particular to a bendable display device.

With the advancement of technology, more and more people are replacing their computer or TV screens with curved screens instead of flat screens. The advantage of a curved screen is that the distance between the screen and the human eye can be kept as consistent as possible when the user is viewing different positions on the screen, thus giving the user a more natural, comfortable, and immersive visual experience. However, when the number of people viewing the same screen increases, the viewing angle of each user will be more dispersed, and viewing a curved screen will be more uncomfortable at this time. Watching a flat screen can give users a wider visual experience. Although some existing screens can adjust the curvature of the screen, there is a problem of complex mechanical structure, which will increase the cost in the manufacturing process.

Therefore, one of the purposes of the present invention is to provide a display device with a simple structure and a bendable screen.

Therefore, the display device of the present invention includes a flexible screen, a track, a driving mechanism, two sliders, two screws, and two pivot units. The flexible screen has a back surface, and the back surface has a central surface, and a left side surface and a right side surface are respectively located on the left and right sides of the central surface. The track is arranged on the back surface of the flexible screen along a left-right direction and defines a slide space. The driving mechanism is arranged in the center of the slide space. The sliders are arranged in the slide space and are located on the left and right sides of the driving mechanism. The screws are connected to the left and right sides of the driving mechanism and are screwed to the sliders respectively, and can be driven by the driving mechanism to rotate, thereby driving the sliders to move toward or away from each other. The pivot units are pivoted to the sliders and are connected to the left and right sides of the back of the flexible screen.

In some embodiments, each pivot unit includes a pivot connected to the back of the flexible screen, and a connecting rod pivotally connected to the corresponding slider and the pivot.

In some embodiments, the track has a locking hole located in the center of the slide rail space and passing through the substrate portion, and the display device further includes a locking fixture passing through the locking hole to fix the center of the track to the center point of the flexible screen.

In some embodiments, each slider has a threaded portion and a pivoted portion located at opposite ends, the threaded portion is threaded with a corresponding screw rod, and the pivoted portion is pivoted with a corresponding connecting rod.

The present invention has the following effects: by arranging a track, a driving mechanism, a slider, a screw and a pivot unit on the back of the flexible screen, the driving mechanism drives the screws to rotate, drives the sliders to move toward or away from each other, and then drives the pivot units to push or pull the flexible screen from the left side and the right side of the flexible screen, so that the flexible screen can be switched between a flat mode and multiple curved modes.

Other features and effects of the present invention will be clearly presented in the implementation method with reference to the drawings, wherein: FIG. 1 is a three-dimensional diagram of an embodiment of the display device of the present invention; FIG. 2 is a partial three-dimensional exploded diagram of the embodiment; FIG. 3 is a top view, illustrating a flexible screen of the embodiment in a plane mode; FIG. 4 is a top view, illustrating the flexible screen in a curved mode; and FIG. 5 is a top view, illustrating the flexible screen in another curved mode. .

Referring to FIG. 1 and FIG. 2 , an embodiment of the display device 100 of the present invention includes a flexible screen 1, a track 2, a locking device 3, a driving mechanism 4, two sliders 5, two screws 6, and two pivot units 7.

The flexible screen 1 has a back surface 11, and the back surface 11 has a central surface 111, and a left surface 112 and a right surface 113 located on the left and right sides of the central surface 111 respectively.

The track 2 is disposed on the back side 11 of the flexible screen 1 along a left-right direction D1 and defines a slide rail space 24. Specifically, the track 2 has a substrate portion 21, an upper slide rail portion 22 and a lower slide rail portion 23 that are bent backward and extend from the top and bottom sides of the substrate portion 21, respectively, and a locking hole 25 located in the center of the slide rail space 24 and passing through the substrate portion 21. The substrate portion 21, the upper slide rail portion 22 and the lower slide rail portion 23 together define the slide rail space 24.

The locking piece 3 is inserted into the locking hole 25 to fix the center of the track 2 to the center point of the flexible screen 1. It should be particularly noted that the track 2 is fixed to the flexible screen 1 only by the locking piece 3, so when the flexible screen 1 is in a flat mode (see FIG. 3), most of the substrate 21 of the track 2 is detachably connected to the flexible screen 1, and when the flexible screen 1 is in a curved mode (see FIG. 4), the left and right sides of the substrate 21 of the track 2 can be separated from the flexible screen 1 depending on the degree of bending of the flexible screen 1.

The driving mechanism 4 is specifically an electric motor and is disposed in the center of the slide rail space 24. The sliders 5 are movably disposed in the slide rail space 24 and are located on the left and right sides of the driving mechanism 4. Each slider 5 is rectangular and has a screw connection portion 51 and a hinge portion 52 located at opposite ends at two short sides.

The screw rods 6 are connected to the left and right sides of the driving mechanism 4 and are respectively screwed to the sliders 5, and can be driven by the driving mechanism 4 to rotate, thereby driving the sliders 5 to move toward or away from each other. The screw rods 6 are respectively screwed to the screw connection parts 51 of the sliders 5.

The pivot units 7 are pivotally connected to the sliders 5 and are connected to the left side surface 112 and the right side surface 113 of the back surface 11 of the flexible screen 1. Specifically, each pivot unit 7 includes a pivot member 71 connected to the back surface 11 of the flexible screen 1, and a connecting rod 72 pivotally connected to the pivot portion 52 of the corresponding slider 5 and the pivot member 71.

In conjunction with FIG. 3 to FIG. 5 , the following paragraphs describe in detail the operation process of the display device 100. The flexible screen 1 can be switched between a plane mode and a plurality of curved modes relative to the track 2. When the flexible screen 1 is in the plane mode, the flexible screen 1 is fully unfolded, and the screw-connected portions 51 of the sliders 5 maintain a predetermined distance, which is the shortest distance between the screw-connected portions 51, and the screw-connected portions 51 are adjacent to the driving mechanism 4. When the driving mechanism 4 is operated to start and rotate the screw rods 6, one of the screw rods 6 rotates in the forward direction and the other screw rod 6 rotates in the reverse direction, the screw rods 6 will drive the sliders 5 to move away from the driving mechanism 4 in opposite directions, so that the sliders 5 drive the connecting rods 72 to move away from the driving mechanism 4. During the movement of the connecting rods 72, the connecting rods 72 will tilt toward the flexible screen 1 with the hinges 52 of the sliders 5 as fulcrums, pushing the hinges 71 to move in an arc shape, thereby driving the flexible screen 1 to bend, so that the flexible screen 1 enters a curved surface mode. Within the limit where the sliders 5 are located at the ends of the screw rods 6, the curvature of the flexible screen 1 can be adjusted arbitrarily according to the viewing habits of the user. Therefore, the flexible screen 1 can have a variety of curved surface modes with different curvatures, which are illustrated in Figures 4 and 5 only, but are not limited to this. In addition, since the track 2 is only fixed to the flexible screen 1 by the locking member 3, when the flexible screen 1 enters the curved mode, most of the substrate portion 21 of the track 2 is separated from the flexible screen 1, and the flexible screen 1 will not have creases in the curved mode because the track 2 is disposed on the back side 11 of the flexible screen 1.

When the user wants to switch back to the planar mode, the drive mechanism 4 is operated to start and rotate the screws 6, so that one of the screws 6 that originally rotated forward changes to reverse rotation, and the other screw 6 that originally rotated reversely changes to forward rotation, so that the sliders 5 drive the connecting rods 72 to move in the direction close to the drive mechanism 4. During the movement of the connecting rods 72, the connecting rods 72 will use the hinges 52 of the sliders 5 as a fulcrum to tilt away from the flexible screen 1, pulling the hinges 71 to move in an arc shape, thereby driving the flexible screen 1 to be flat, so that the flexible screen 1 enters the planar mode.

In summary, the display device 100 of the present invention is provided with a track 2, a driving mechanism 4, a slider 5, a screw 6 and a pivot unit 7 on the back 11 of the flexible screen 1. The driving mechanism 4 drives the screws 6 to rotate, driving the sliders 5 to move toward or away from each other, thereby driving the pivot units 7 to push or pull the flexible screen 1 from the left side surface 112 and the right side surface 113 of the flexible screen 1, so that the flexible screen 1 can be switched between a flat mode and multiple curved modes, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
