Fig. 2 is a schematic structural diagram of a display device in a three-dimensional state according to an embodiment of the present invention. Fig. 3 is a schematic structural diagram of a display device in a stacked and accommodated state according to an embodiment of the present invention.

According to an embodiment provided by the present invention, a display device includes: a plurality of sub-screens 100 and a sliding assembly 200; at least some of the sub-screens 100 of the plurality of sub-screens 100 are relatively and rotatably connected in pairs and relatively and slidably connected through the sliding assembly 200, so that the plurality of sub-screens 100 can be at least changed between a three-dimensional state and a stacked storage state.

The sub-screen 100 includes, for example, a display surface and a back surface which are oppositely arranged in a thickness direction thereof, and a side surface connected between the display surface and the back surface. Preferably, when the sliding member 200 is provided on the sub-screen 100, the sliding member 200 is provided on the back and/or side of the sub-screen 100, so as not to affect the normal display of the sub-screen 100.

It is further preferable that the display surfaces of the plurality of sub-screens 100 are on the same side when the display apparatus is in the stereoscopic state, for example, the display surfaces of the plurality of sub-screens 100 are on the inner or outer sides, as shown in fig. 2, and the display surfaces of the plurality of sub-screens 100 are on the outer or inner surfaces of the polyhedron, thereby realizing stereoscopic display.

In the display device according to the embodiment of the present invention, the display device includes a plurality of sub-screens 100, at least some of the sub-screens 100 in the plurality of sub-screens 100 are relatively rotatably connected, and the display device further includes a sliding assembly 200, so that at least some of the sub-screens 100 can be slidably connected to each other through the sliding assembly 200. At least some of the sub-screens 100 of the plurality of sub-screens 100 are rotatably connected in pairs and slidably connected in pairs through the sliding assemblies 200, so that at least some of the sub-screens 100 of the plurality of sub-screens 100 can rotate and slide relative to each other, and the display device can be changed between a stereoscopic state and a stacked storage state. When display device is in the stereoscopic state, thereby can realize that stereoscopic display satisfies the stereoscopic display demand, when display device is in range upon range of state of accomodating, it is less to occupy the space, is convenient for accomodate. Therefore, the display device provided by the embodiment of the invention can realize three-dimensional display, can reduce the volume of the display device and is convenient to carry and store.

In some alternative embodiments, the plurality of sub-screens 100 can be further transformed to a planar state, that is, the plurality of sub-screens 100 can be transformed in a stereoscopic state, a stacked storage state, and a planar state, wherein in the planar state, the plurality of sub-screens 100 are arranged in a common plane. Thereby enabling a plurality of sub-screens 100 to implement a flat display.

Preferably, when the plurality of sub-screens 100 are in a planar state, the display surfaces of the plurality of sub-screens 100 are oriented the same, so that the plurality of sub-screens 100 can be displayed in the same direction.

It is understood that in different states, the display device can perform display, for example, in a stereoscopic state, the display device can perform stereoscopic display; at least one sub-screen 100 in the display device can display in the stacked and stored state, and preferably, the sub-screen 100 positioned outside the stacked and stored state can display; in the flat state, at least one sub-screen 100 of the display device can be displayed, and preferably, in the flat state, all the sub-screens 100 can be displayed to realize a flat display.

There are various ways to rotatably connect the two sub-screens 100 to each other, for example, the two sub-screens 100 adopt a flexible screen arrangement, so that the two sub-screens 100 can be folded and rotated with each other.

In other alternative embodiments, please refer to fig. 4 and 5 together, fig. 4 is a schematic diagram illustrating a partial enlarged structure of a display device according to an embodiment of the present invention; fig. 5 is a schematic diagram of a partially enlarged structure of a display device according to another embodiment of the invention.

According to the embodiment shown in fig. 4 and 5, the display device further includes a rotating assembly 300, and at least some of the sub-screens 100 are rotatably coupled to each other two by the rotating assembly 300. Preferably, when the rotation member 300 is disposed on the sub-screen 100, the rotation member 300 is disposed on the back or side of the sub-screen 100.

There are various ways of mutually switching among the plurality of sub-screens 100 between the stacked and accommodated state, the stereoscopic state and the planar state, for example, the plurality of sub-screens 100 are switched between the stacked and accommodated state and the planar state by the sliding assembly 200; and/or, the plurality of sub-screens 100 are switched between the stereoscopic state and the planar state by the rotating assembly 300; and/or the plurality of sub-screens 100 are arbitrarily changed between the stereoscopic state, the stacked storage state and the planar state by the rotation assembly 300 and the sliding assembly 200.

In some alternative embodiments, one sub-screen 100 of the plurality of sub-screens 100 is at least slidably connected to another sub-screen 100 through a sliding assembly 200, and the sub-screen 100 can slide to the display surface and the back surface of another sub-screen 100.

As shown in fig. 1 to 3, six sub-screens 100 are taken as an example to illustrate an arrangement manner of the display device according to the present invention, and the six sub-screens 100 are a first screen 110, a second screen 120, a third screen 130, a fourth screen 140, a fifth screen 150, and a sixth screen 160, respectively.

In fig. 1, a first screen 110 is slidably coupled to another second screen 120 through a sliding member 200, and a sixth screen 160 is slidably coupled to another fifth screen 150 through a sliding member 200.

It is to be understood that, although each of the plurality of sub-screens 100 shown in fig. 1 is rotated to the stereoscopic state, at least some of the plurality of sub-screens 100 may be changed to the stereoscopic state to implement stereoscopic display. For example, only three sub-screens of the six sub-screens 100 rotate in a triangular prism shape, thereby being converted into a stereoscopic state to implement stereoscopic display.

In other alternative embodiments, the plurality of sub-screens 100 includes an intermediate connection screen, and the intermediate connection screen is slidably connected to at most two other sub-screens 100 through two sets of sliding members 200. So that one of the other two sub-screens 100 can slide to the display surface of the intermediate connection screen and the other can slide to the back surface of the intermediate connection screen. Thereby can reduce the shared space of display screen when fold condition as far as, be convenient for more accomodate.

Still taking the above fig. 1 as an example, the third screen 130 and the fourth screen 140 are intermediate connection screens, the third screen 130 is slidably connected to each other through two sets of sliding components 200 and the second screen 120 and the fourth screen 140, and the fourth screen 140 is slidably connected to each other through two sets of sliding components 200 and the third screen 130 and the fifth screen 150.

In some alternative embodiments, at least two sub-screens 100 of the plurality of sub-screens 100 are connected to each other by the rotating member 300 and the sliding member 200, and one of the two sub-screens 100 connected to each other by the rotating member 300 and the sliding member 200 is movable in a first direction with respect to the other by the sliding member 200 and is rotatably disposed by the rotating member 300 about a rotation axis extending in a second direction. The rotation axis does not limit the structure of the display device according to the embodiment of the present invention, and the rotation axis is only used to clearly indicate the rotation direction of the sub-screens 100 connected to each other by the rotation member 300. The two sub-screens 100 connected to each other by the rotation assembly 300 are rotatably disposed about the rotation axis.

The first direction and the second direction intersect, preferably the sliding direction is perpendicular to the direction of extension of the axis of rotation, i.e. the first direction and the second direction are perpendicular.

In these alternative embodiments, the two sub-screens 100 are both slidably connected to each other by the sliding member 200 and rotatably connected to each other by the rotating member 300, and the extending direction and the sliding direction of the rotation axis are not coincident, so that the display device can be changed between a multi-state in which the display device is in a three-dimensional state, a stacked storage state, and a planar state.

It is understood that the first direction indicates a direction in which a set of two sub-screens 100 connected to each other by the sliding member 200 slides with respect to each other, and the second direction indicates a direction in which the rotational axes of the set of two sub-screens 100 extend. In two sets of two sub-screens 100 connected to each other by the sliding member 200, the sliding directions of the two sets may be the same or different, and the extending directions of the rotation axes may be the same or different.

Still taking the above-mentioned fig. 1 as an example, the first screen 110 and the second screen 120 are slidably connected in the X direction in fig. 1, and the rotation axis between the first screen 110 and the second screen 120 extends in the Y direction. Similarly, the second screen 120 and the third screen 130 are slidably coupled in the X direction in fig. 1, and the rotation axis between the second screen 120 and the third screen 130 extends in the Y direction.

However, the third screen 130 and the fourth screen 140 are slidably coupled in the Y direction in fig. 1, and the rotation axis between the third screen 130 and the fourth screen 140 extends in the X direction.

Likewise, the fourth screen 140 and the fifth screen 150 are slidably coupled in the X direction in fig. 1, and the rotation axis between the fourth screen 140 and the fifth screen 150 extends in the Y direction. Likewise, the fifth screen 150 and the sixth screen 160 are slidably coupled in the X direction in fig. 1, and the rotation axis between the fifth screen 150 and the sixth screen 160 extends in the Y direction.

As can be seen from the above-described embodiment, the sliding direction between the first screen 110 and the second screen 120 is the same as the extending direction of the rotation axis between the third screen 130 and the fourth screen 140. When the sliding direction of the set of sub-screens 100 of the first screen 110 and the second screen 120 and the sliding direction of the set of the third screen 130 and the fourth screen 140 are different, the extending direction of the rotation axis of the set of sub-screens 100 of the first screen 110 and the second screen 120 and the extending direction of the rotation axis of the set of the third screen 130 and the fourth screen 140 are also different.

The sliding assembly 200 can be arranged in various ways, and in some alternative embodiments, the sliding assembly 200 includes a sliding rail 210 and a sliding block 220, which are slidably connected with each other, in two sub-screens 100 connected with each other through the sliding assembly 200: one of the two is provided with a slide rail 210 extending and forming along a first direction, and the other is provided with a slide block 220; at least one end of the slide rail 210 in the first direction is provided with a locking groove 230, so that the slide block 220 can be limited in the locking groove 230.

In these alternative embodiments, the two sub-screens 100 connected to each other through the sliding assembly 200 can slide relative to each other through the sliding and sliding rail 210, and when the sliding block 220 is limited in the slot 230, it can also be ensured that the position between the two sub-screens 100 is relatively stable, so that the display device can be stably in a stacked storage state or a planar state.

In some alternative embodiments, when the sub-screen 100 is provided with the slider 220, the slider 220 is provided, for example, at a side of the sub-screen 100. When the slide rail 210 is disposed on the sub-screen 100, the slide rail 210 is disposed on the back surface of the sub-screen 100, for example, so that the slide rail 210 can be extended and molded on the back surface along the first direction. And preferably, the opposite ends of the slide rail 210 in the extending direction thereof are located on the back surface near the side surfaces. The extending distance of the sliding rail 210 is longer, the display device can be changed between the states more fully, and the display area of the display device in the three-dimensional state can be increased under the condition that the size of the sub-screen 100 is not changed.

Still taking fig. 1 as an example, a slider 220 is disposed on a side surface of the first screen 110, a slide rail 210 is disposed on a back surface of the second screen 120, and the slider 220 is slidably disposed in the slide rail 210, so that both the first screen 110 and the second screen 120 can be switched between a stacked storage state and a planar state, and when the first screen 110 and the second screen 120 are in the stacked storage state and/or the planar state, the slider 220 is limited in the slot 230, and a relative position of the first screen 110 and the second screen 120 is more stable.

Preferably, both ends of the slide rail 210 in the first direction are provided with a locking groove 230, so that the stability of the relative position between the two sub-screens 100 connected to each other by the slide assembly 200 can be ensured regardless of whether the display device is in the stacked storage state or the flat state.

Still taking fig. 1 as an example, when the two ends of the sliding rail 210 in the first direction are both provided with the card slots 230, when the first screen 110 and the second screen 120 are in the stacked storage state and the planar state, the sliding block 220 can be both limited to the card slots 230.

There are various ways to retain the slider 220 to the slot 230, for example, the slider 220 and the slot 230 are in interference fit.

Or, in other alternative embodiments, the card slot 230 is formed to extend along the second direction, the card slot 230 has a limiting recess 231 and an opening 232 communicating with the slide rail 210, and the limiting recess 231 is located on one side of the opening 232 in the second direction; the sliding block 220 is movably disposed in the second direction relative to the sub-screen 100 on which the sliding block 220 is disposed, so that the sliding block 220 can be limited in the limiting recess 231 or moved along the sliding rail 210 by the opening 232.

In the same slide rail 210 assembly, the number of the slide blocks 220 and the number of the slide rails 210 are not limited, preferably, two slide blocks 220 are provided, and the two slide blocks 220 are distributed at intervals along the second direction; the number of the slide rails 210 is two, and the two slide rails 210 are respectively disposed corresponding to the two sliders 220, so that one of the two sub-screens 100 connected to each other through the slide rail 210 assembly can be movably disposed relative to the two slide rails 210 through the two sliders 220.

There are various ways in which the slider 220 is movably disposed in the second direction relative to the sub-screen 100 on which the slider 220 is disposed, for example, a link 240 is connected between two sliders 220 on the same sub-screen 100, and the slider 220 can be driven to move in the second direction relative to the sub-screen 100 on which the slider 220 is disposed by the link 240.

In still other alternative embodiments, the limiting recesses 231 disposed on the same side of the two sliding rails 210 on the same sub-screen 100 are located on the sides close to or away from the openings 232, the connecting rod 240 is a telescopic rod, and the two sliding blocks 220 are moved along the second direction and located in the limiting recesses 231 or moved along the sliding rails 210 by the openings 232 by adjusting the length of the connecting rod 240.

Still taking fig. 1 as an example, and referring to fig. 4 and 5, two sliders 220 are disposed on one side of the first screen 110, two slide rails 210 are disposed on the second screen 120, and the two sliders 220 can slide along the two slide rails 210 respectively. The two limiting recesses 231 on the same side of the two sliding rails 210 on the second screen 120 are located on the far side of the two openings 232. That is, as shown in the direction of the drawing in fig. 1, the stopper recess 231 on the upper slide rail 210 side is located above the opening 232, and the stopper recess 231 on the lower slide rail 210 side is located below the opening 232. A telescopic link 240 is connected between the two sliders 220, when the link 240 contracts and shortens, the slider 220 corresponds to the opening 232 and can move along the slide rail 210 from the opening 232, and when the link 240 extends and lengthens, the two sliders 220 are respectively limited in the limit concave parts 231.

In some alternative embodiments, the rotating assembly 300 includes a first mating member 310 disposed on the slot 230 and a second mating member 320 disposed on the sliding block 220, so that when the sliding block 220 is limited on the slot 230, the first mating member 310 and the second mating member 320 can be mated with each other; the first mating member 310 is rotatably disposed in the slot 230 around a rotation axis extending along the second direction, so that the first mating member 310 can drive the second mating member 320 and the sub-screen 100 where the second mating member 320 is located to rotate around the rotation axis.

In these alternative embodiments, the rotation member 300 and the sliding member 200 are organically combined, so that the two sub-screens 100 slidably coupled to each other by the sliding member 200 can also be rotated with each other by the rotation member 300.

The first mating member 310 and the second mating member 320 may be disposed in various ways, for example, the first mating member 310 is a first gear disposed in the card slot 230; the second mating member 320 is a second gear disposed on the slider 220 and capable of meshing with the first gear. When the sliding block 220 slides to the limiting concave portion 231, the first gear and the second gear are engaged with each other, and the first gear drives the second gear to rotate, so as to drive the sub-screen 100 where the second gear is located to rotate.

There are various relative positional relationships between the second mating member 320 and the sliding block 220, for example, the second mating member 320 may be gear teeth disposed on the circumference of the sliding block 220, so that the sliding block 220 can be engaged with the first gear through the gear teeth. Or the second mating member 320 is located inside the sliding block 220, which does not affect the sliding block 220 moving along the sliding rail 210, and when the sliding block 220 moves to the limiting recess 231, the first mating member 310 and the second mating member 320 are engaged with each other inside the sliding block 220.

In some alternative embodiments, at least two sub-screens 100 of the plurality of sub-screens 100 are communicatively connected, so that one of the communicatively connected two sub-screens 100 can display a display of the other. When the two sub-screens 100 are in the stacked storage state, the sub-screen 100 located on the outer side can display the screen of the sub-screen 100 located on the inner side. Preferably, the plurality of sub-screens 100 have a main display screen, and the main display screen is communicatively connected to the other sub-screens 100 so that the main display screen can display the screens of the other sub-screens 100, and the main display screen is located outside in the stacked storage state.

Still taking the embodiment shown in fig. 1 to 3 as an example, the sixth screen 160 is a main display screen, and in the stacked and accommodated state, the first screen 110, the second screen 120, the third screen 130, the fourth screen 140, the fifth screen 150 and the sixth screen 160 are sequentially arranged from bottom to top, and the sixth screen 160 is a main display screen capable of displaying the display screens of five sub-screens 100 located below the sixth screen 160. Therefore, even in the folded and stored state, the display device can still display all the images of the sub-screen 100, and the display requirements are met.

In some alternative embodiments, in the stacked storage state, the display surfaces of the plurality of sub-screens 100 face the same direction, and the display surfaces of the two sub-screens 100 are prevented from being opposite to each other, so that the display surfaces are prevented from being worn away from each other.

When the number of the sub-screens 100 is six, the structure when the six sub-screens 100 are in the planar state is not limited to that shown in fig. 1, and the structure when the six sub-screens 100 are in the planar state may also be as shown in fig. 6 to 8.

The number of the sub-screens 100 may be not only six, but also three, four, and the like, for example.

Referring to fig. 9 to 10, fig. 9 is a schematic structural diagram of a display device in a planar state according to another embodiment of the present invention; fig. 10 is a schematic structural view of the display device of fig. 9 in a three-dimensional state.

In the embodiment shown in fig. 9 and 10, the sub-screens 100 are three and the sub-screens 100 are rectangular, and in the planar state, the three sub-screens 100 are sequentially arranged. In the stereoscopic state, the three sub-screens 100 are rotated and enclosed with each other by the rotation member 300 to form a triangular prism, so that the display device can display three sides. In the stacked and stored state, two sub-screens 100 of the three sub-screens 100 are stacked on each other, thereby further reducing the volume of the display device in the stacked and stored state.

When there are three sub-screens 100, the sub-screens 100 may also be triangular, and in a three-dimensional state, the three sub-screens 100 may form a triangular pyramid without a bottom surface. When there are three sub-screens 100, the sub-screens 100 may have other shapes, which are not exhaustive.

Referring to fig. 11 to 12, fig. 11 is a schematic structural diagram of a display device in a planar state according to another embodiment of the present invention; fig. 12 is a schematic structural view of the display device of fig. 11 in a three-dimensional state.

In the embodiment shown in fig. 11 and 12, the number of the sub-screens 100 is four, and when the number of the sub-screens 100 is four, the four sub-screens 100 may be triangular, the four sub-screens 100 may be rotatably connected to each other through side surfaces thereof, and in a three-dimensional state, the four screen rotating assemblies 300 may be rotated to enclose each other to form a triangular pyramid structure. Alternatively, the four sub-screens 100 are converted into the stacked storage state by the sliding assembly 200.

When the sub-screen 100 is four, the sub-screen 100 may also be rectangular or other shapes, which is not exhaustive.

While the application has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the application. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present application is not intended to be limited to the particular embodiments disclosed herein but is to cover all embodiments that may fall within the scope of the appended claims.
