Detailed Description
The technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the description of the present application, it is to be understood that the terms "connected," "fixed," and the like are used in a broad sense and, for example, may be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other suitable relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In a first aspect, referring to fig. 1 and fig. 2 together, an embodiment of the present application provides a flexible display device 100, which is applied to electronic devices such as televisions, computer monitors, portable advertisement players, and notebook computers. The flexible display device 100 comprises an extension supporting member 10 and a flexible screen member 20, wherein the extension supporting member 10 comprises at least one multi-stage telescopic member 12 and a containing cavity 11, the flexible screen member 20 comprises a flexible screen 21 and a safety flexible layer 22, and the safety flexible layer 22 is connected to the back surface of the flexible screen 21 in a laminated manner. When the flexible screen member 20 is at an accommodating position, the flexible screen member 20 is accommodated in the accommodating cavity 11 and is connected to one end of the multi-stage extensible member 12, each of the multi-stage extensible members 12 is stacked and retracted together, and when the flexible screen member is at an extending position, the multi-stage extensible member 12 extends in a multi-stage manner, and supports and drives the safe flexible layer 22 to extend along any extending direction of the multi-stage extensible member 12 including vertical rising, so that at least a part of the flexible screen member 20 is pulled out of the accommodating cavity 11, and is supported to reach a fixed height of any stroke, thereby completing size conversion of the display area of the flexible screen 21.
For example, the shape of the receiving cavity 11 in the extending support member 10 may be a cylinder, a cube, or a special-shaped body, as long as there is a cavity with a certain receiving space, and the present application is not limited specifically. The housing of the receiving cavity 11 may be an overall shape of the device, or may be an overall shape of the device, a main body of the device, or the like, which are all installed in the receiving cavity 11 together, and the present application is not limited specifically. The multiple stages of the multi-stage telescopic member 12 may be two, three, four, five, six, seven, eight, or more stages, and the present application is not limited specifically. When in a containing position, the flexible screen 21 member 20 is contained in the containing cavity 11, the multi-stage extensible member 12 can be completely contained in the containing cavity 11, and the overall volume of the device or equipment can be the overall volume of the containing cavity 11; in a non-fully extended position, a user may exert an external force to partially extend the multi-stage telescopic member 12, so as to drive the connected safety flexible layer 22, and a portion of the safety flexible layer is pulled out of the receiving cavity 11, and the flexible screen 21 attached to the safety flexible layer 22 is partially displayed in a plane along the extending direction of the multi-stage telescopic member 12; in a fully extended position, the multi-stage extensible member 12 is further pulled out completely step by step, thereby driving the safety flexible layer 22, most of which is pulled out of the receiving cavity 11, so that the flexible display screen is displayed on a plane completely. Since the multi-stage telescopic member 12 can be elongated one by one and can be fixed at will during the elongation process, there is no limitation on the directivity, and the flexible screen member 20 can be supported to a fixed height of any stroke thereof, including a vertical rise, thereby completing the size conversion of the display area of the flexible screen 21. Due to the adoption of the technical means of multistage extension of the multistage extensible member 12, the multistage extension drives the flexible screen 21 to display to a greater extent through the one-stage and one-stage retraction of the multistage extensible member 12 in the accommodating cavity 11 during the accommodating process, and the multistage extension drives the flexible screen 21 to display to a greater extent through the multistage pulling of the safe flexible layer 22 during the expansion process, so that the area displayed by the flexible screen 21 is larger, and the technical effect of small-volume and large-display is realized.
Further, referring to fig. 2 and fig. 3, as an alternative embodiment, when the number of the multistage telescopic elements 12 is two, two of the multistage telescopic elements are disposed in parallel at two ends of the receiving cavity opening 111, and are preferably perpendicular to the receiving cavity opening 111. Specifically, the two ends of the accommodating cavity opening 111 may be the outer ends of the two opposite side edges of the accommodating cavity opening 111, or the two opposite side edges of the accommodating cavity opening 111 intersect at the two ends of the same side edge, which is not specifically limited in this application; the number of the multistage telescoping members 12 is not particularly limited. When the number of the multi-stage telescopic parts 12 is one, the multi-stage telescopic parts 12 are connected and supported in the central extending direction of the back of the flexible screen member 20; when the number of the multi-stage telescopic parts 12 is preferably two, the multi-stage telescopic parts 12 are connected and supported in the extending direction of two sides of the flexible screen member 20 or two sides of the back part thereof; the two parts of the support are mutually parallel and cooperate to support and extend, so that the stability of the extending support can be improved.
Further, referring to fig. 2 and fig. 3, as an alternative embodiment, a winding shaft 112 is disposed in the receiving cavity 11, and the flexible screen member 20 is wound around the winding shaft 112, and has one end connected to the winding shaft 112. It is understood that in other embodiments, the flexible screen member 20 may be received in the receiving cavity 11 in a manner of being folded inwards and outwards alternately or in a manner of being curved by the sliding cavity. The winding mode of the flexible screen member 20 may be an outward bending winding mode in which the flexible screen 21 is on the outer layer of the circular arc and the safe flexible layer 22 is attached to the inner layer of the circular arc, or an inward bending winding mode in which the flexible screen 21 is on the inner layer of the circular arc and the safe flexible layer 22 is attached to the outer layer of the circular arc, and the present application is not limited specifically.
Further, referring to fig. 3 to 5, as an alternative embodiment, the multi-stage telescopic element 12 includes a multi-stage telescopic rod 121. It can be understood that the multi-section telescopic rod 121 is used as a support rod type frame structure with closely stacked sections, and has a smaller volume, i.e. a smaller occupied space, and a larger number of sections, i.e. a larger extension length, compared with the conventional laminated plate type support structure, thereby being beneficial to portability and large-area display; meanwhile, the multi-section telescopic rod 121 is simple in structure and low in cost, and therefore production efficiency is improved. In the display of the flexible screen 21 with a larger width, the number of the multiple telescopic rods 121 can also be three or more, and then the multiple telescopic rods 121 are connected and supported on the back of the flexible screen member 20 in the extending direction with uniform intervals or non-uniform intervals.
Further, referring to fig. 3, as an alternative embodiment, the safety flexible layer 22 includes a plurality of springs 221, a cloth 222 and metal strips 223 wound side by side, the cloth 222 is at least one layer, at least one layer of the cloth 222 is attached to one side of the springs 221 which are not completely unfolded, and at least one layer is penetrated by each layer or part of the layer of each spring 221, the penetrated cloth 222 is integrally woven with the cloth 222 which is not penetrated, and each metal strip 223 is sequentially penetrated at the intersection of every two adjacent springs 221 below the penetrated cloth 222; the diameter of the metal strip 223 has a certain length, and when the flexible screen 21 is folded in safely, the radius of a cavity formed by the safe flexible layer 22 at the folding position is larger than or equal to the minimum folding curvature radius of the flexible screen 21, so that the flexible screen 21 can be folded in and out safely when accidents occur. Specifically, the extension lengths of the springs 221 and the metal strips 223 and the extension width of the cloth 222 are both approximately equal to the width of the flexible screen 21, the springs 221 under incomplete unfolding are structural states when each layer of adjacent springs 221 intersects at two points, a plurality of springs 221 wound side by side can be woven on a connecting cloth surface by double layers of the cloth 222, the cloth 222 has a certain length and the length is unchanged, so that the lengths of the flexible screens 21 connected in a stacked manner are protected from being changed, only when the flexible screen 21 is folded outwards accidentally, the volume of a support structure contained by the flexible screen 21 needs to be reduced, and the adjacent springs 221 wound together are close to each other to be matched with each other to reduce the volume and form a support inner arc surface; when the flexible screen 21 is folded inwards accidentally, the volume of the supported structure of the flexible screen 21 needs to be increased, and the adjacent springs 221 which are threaded together are far away from each other to adapt to the expanded volume and form a supporting extrados; the formation of the support extrados requires the penetration and matching of the metal strips 223, the length of one layer of the cloth 222 in the arc layer is fixed, the spring 221 sequentially crosses two dynamic layers at two points outside the arc and rotates towards the dynamic layer crossing one point, meanwhile, the metal strips with certain diameter and length clamped between the two layers are pressed by the dynamic layer and are closely arranged on the arc layer outside the fixed-length cloth layer, and under the combined action of the elasticity of each spring 221 and the opposite tension of the cloth 222, the cavity radius required by the inward folding is formed.
When the thickness of the flexible display screen can be 0.1 mm to 0.66 mm, the folding radius can reach the extreme size of 1 mm, the wire diameter of the precise spring can be 0.15 mm, the radius of the precise spring can be 0.5 mm, and the size of the safe flexible layer 22 wound by the springs 221 is smaller, so that the occupied volume is smaller, the safe flexible layer can be safely folded inside and outside in an accident, and the flexible screen 21 is further protected from being damaged.
As an alternative embodiment, the safety flexible layer 22 includes a plurality of springs 221, a cloth 222 and metal strips 223 wound side by side, the cloth 222 is at least one layer, at least one layer of the cloth 222 is attached to one side of the springs 221 which are not completely unfolded, at least one layer is penetrated by each layer or part of the layer of each spring 221, the penetrated cloth 222 is integrally woven with the non-penetrated cloth 222, and each metal strip 223 is sequentially penetrated through each partial spring hole exposed on the penetrated cloth 222; the diameter of the metal strip 223 has a certain length, and when the flexible screen 21 is folded in safely, the radius of a cavity formed by the safe flexible layer 22 at the folding position is larger than or equal to the minimum folding curvature radius of the flexible screen 21, so that the flexible screen 21 can be folded in and out safely when accidents occur. It can be understood that the principle and implementation of the metal strip 223 penetrating through the local spring hole of the penetrated cloth 222 and the intersection of the metal strip 223 penetrating through the penetrated cloth 222 and adjacent to the outside of the spring 221 are substantially similar, and detailed description is omitted here, and please refer to the above embodiment specifically. In other embodiments, the safety flexible layer 22 may also be a continuous hinge, but the hinge cannot be folded at both sides, and the flexible screen 21 can only be folded at one side in the hinge side direction, so that the safety coefficient is low, the thickness is large, and the flexible screen 21 cannot be safely protected in an accident.
Further, referring to fig. 3, as an alternative embodiment, the flexible screen 21 further includes a metal sheet 30, and the metal sheet 30 is connected between the safety flexible layer 22 and the flexible screen 21 in a stacked manner, so that the flexible screen 21 is further protected. In practice, the metal sheet 30 includes, but is not limited to, an extremely thin steel sheet including, but not limited to, a perforated steel sheet with a plurality of intermittent and parallel strip holes, so that the local tension of the flexible screen 21 is released through the strip holes in line with the direction of extension.
Further, referring to fig. 3 and 4, as an alternative embodiment, the support beam 40 further includes a half-moon-shaped rod cylinder 41 and a central rod 42 clamped in the half-moon-shaped rod cylinder 41, two ends of the half-moon-shaped rod cylinder 41 are respectively and vertically connected to one end of each of the two parallel multi-stage telescopic members 12, and the central rod 42 is fixedly connected to one end of the safety flexible layer 22; wherein, the supporting beam 40 can drive the multistage telescopic member 12 to extend in multiple stages, and the flexible screen member 20 can be displayed on a plane; the central rod 42 can also be detached from the half-moon-shaped rod cylinder 41, and drives the flexible screen member 20 to unfold and display the flexible curved surface of various shapes. Specifically, the half-moon-shaped rod cylinder 41 may be made of an elastic metal material, and the radius of the circular arc-shaped opening may be designed to be smaller, so as to clamp the central rod 42 through the elasticity of the metal; of course, the way of the matching and clamping of the buckle and the clamping groove can be designed. Due to the adoption of the structure that the springs 221 which are wound side by side are further penetrated by the connecting layer of the cloth 222 and the safe flexible layer 22 penetrated by the metal strip 223, the thin safe flexible layer 22 supports the flexible screen 21, and can be safely folded inwards and outwards when an accident occurs, so that the flexible screen can be separated from the rigid support of the multistage extensible member 12 to display a flexible curved surface. The flexible screen 21 is displayed to the utmost extent, and the user has more experience of selection.
Further, referring to fig. 3 and 5, as an alternative embodiment, a buffer edge 50 is further disposed at one end of the safety flexible layer 22, and the buffer edge 50 is connected between the central rod 42 and the safety flexible layer 22, so that excessive tension and external force impact during the unfolding process are relieved and are within a safety deformation threshold range of the flexible screen 21. It is understood that the buffer edge includes, but is not limited to, a telescopic cloth, a light tension spring; any elastic member may be used.
