[ detailed description ] of the application
The application is described in further detail below with reference to the drawings and examples. It is specifically noted that the following examples are only for illustrating the present application, but do not limit the scope of the present application. Likewise, the following examples are only some, but not all, of the examples of the present application, and all other examples, which a person of ordinary skill in the art would obtain without making any inventive effort, are within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic cross-sectional structure of a display device according to an embodiment of the application. As shown in fig. 1, the display device 10 may include a bottom case 11, a first slide cover 12, a second slide cover 13, and a flexible display screen 14. Wherein the first slide cover 12 may be fixed on the bottom case 11, and in one example, the first slide cover 12 may be fixed on an inner bottom surface of the bottom case 11 by an adhesive or a screw. The second slider 13 is slidably connected to the first slider 12, i.e. the second slider 13 is slidable relative to the first slider 12. The flexible display 14 may include opposite first and second ends 14A, 14B and may have a stowed state, an extended state, and a collapsed state to enable the display device to have three configurations of stowing, extending, and collapsing.
Specifically, as shown in fig. 1, when the flexible display screen 14 is in the storage state, the first slide cover 12 and the second slide cover 13 may be stacked on the bottom case 11, and the first end 14A of the flexible display screen 14 may be located at a side of the second slide cover 13 facing away from the first slide cover 12, and the second end 14B may be stored between the first slide cover 12 and the bottom case 11. When the display device 10 is in operation, the first end 14A of the flexible display 14 may be controlled to be displayed, and the second end 14B of the flexible display 14 may be controlled not to be displayed, so as to realize the display of the storage mode of the display device 10, thereby being beneficial to the carrying of the user.
Specifically, as shown in fig. 1 and 2, when the flexible display 14 is switched from the storage state to the unfolded state, the first end 14A of the flexible display 14 slides together with the second slide 13 relative to the first slide 12, so as to bring the second end 14B of the flexible display out of the storage space between the first slide 12 and the bottom case 11 to a side of the first slide 12 facing away from the bottom case 11. When the display device 10 is operated, the first end 14A and the second end 14B of the flexible display 14 can be controlled to display the display device 10 in the unfolded state, so that the display area of the display device 10 is greatly increased.
Specifically, as shown in fig. 2 and 3, when the flexible display 14 is switched from the unfolded state to the folded state, the first end 14A of the flexible display 14 moves together with the second slider 13 in a direction approaching the second end 14B of the flexible display 14, so that the flexible display 14 is bent. Moreover, when the display device 10 works, the first end 14A and the second end 14B of the flexible display screen 14 can be controlled to display so as to display the folded form of the display device 10, thereby realizing the large-screen display function and the folded display function of the display device at the same time, and greatly improving the user experience effect.
In one embodiment, as shown in fig. 2, when the flexible display 14 is in the unfolded state, the second sliding cover 13 and the first sliding cover 12 may be located in the same plane and jointly provide support to the flexible display 14. Specifically, the surface of the second sliding cover 13 facing the flexible display screen 14 and the surface of the first sliding cover 12 facing the flexible display screen 14 may be both flat surfaces and located in the same plane, so as to ensure that the flexible display screen 14 in the unfolded state can be located in the same plane.
In some embodiments, as shown in fig. 4, the display device 10 may further include a front frame 15, where the front frame 15 surrounds the second sliding cover 13 and fixes the first end 14A of the flexible display screen 14 and the second sliding cover 13. In one example, the first end 14A of the flexible display 14 may be fixed to the second slider 13 by an adhesive, and the front frame 15 may further fix an edge of the first end 14A of the flexible display 14 and an edge of the second slider 13.
Specifically, when the flexible display screen 14 is switched from the storage state to the expanded state, the front frame 15 slides together with the first end 14A of the flexible display screen 14 and the second slide cover 13 relative to the first slide cover 12, so as to drive the second end 14B of the flexible display screen 14 to move out of the storage space between the first slide cover 12 and the bottom case 11 to a side of the first slide cover 12 away from the bottom case 11, thereby realizing the expansion and pull-out of the flexible display screen 14.
In some embodiments, in order to achieve the sliding connection between the first slide cover 12 and the second slide cover 13, as shown in fig. 5 and 6, a first sliding groove 131 may be disposed on a surface of the second slide cover 13 facing away from the first end 14A of the first flexible display screen 14, a first guide rail 121 may be disposed on a surface of the first slide cover 12 facing away from the bottom case 11, and the first sliding groove 131 on the second slide cover 13 may slide in the first guide rail 121 on the first slide cover 12, and accordingly, a sliding direction of the first end 14A of the flexible display screen 14, the second slide cover 13, and the front frame 15 may correspond to a length direction of the first guide rail 121 on the first slide cover 12.
In some embodiments, as shown in fig. 4, the display device 10 may further include a rotation shaft 16, the rotation shaft 16 may be fixed to the bottom case 11, and a rotation axis of the rotation shaft 16 may be perpendicular to a sliding direction of the front frame 15.
Specifically, as shown in fig. 4 and 7, a guide groove 161 may be formed in the rotating shaft 16, a guide protrusion 151 may be formed in the front frame 15, and the guide grooves 161 and the guide protrusions 151 may be in one-to-one correspondence. When the flexible display 14 is switched from the storage state to the extended state, that is, when the display device 10 is switched from the storage state to the extended state, as shown in fig. 7 and 8, the guide projection 151 of the front frame 15 slides into the guide groove 161 of the rotating shaft 16 (as shown in the structure of fig. 8 in circle C) to rotatably connect the front frame 15 to the rotating shaft 16. In one example, the number of the rotating shafts 16 may be two, and the two rotating shafts 16 may be symmetrically disposed at two opposite corners of the bottom case 11.
It will be appreciated that, as shown in fig. 9, after the front frame 15 is rotatably connected to the rotating shaft 16, the front frame 15, the first end 14A of the flexible display screen 14, and the second sliding cover 13 may be operated around the rotation axis of the rotating shaft 16 under the action of external force, so as to change the flexible display screen 14 from the unfolded state to the folded state, that is, to enable further folding of the flexible display screen 14 after the flexible display screen 14 is unfolded.
In a specific embodiment, after the front frame 15, the first end 14A of the flexible display 14, and the second slide cover 13 move around the rotation axis of the rotation shaft 16 under the action of an external force and form an included angle smaller than 180 degrees with the first slide cover 12, the rotation shaft 16 can keep the included angle unchanged or substantially unchanged to a certain extent when the external force is removed, so that the user can use the display device 10 in the folded configuration.
In some embodiments, as shown in fig. 4, 10 and 11, the display device 10 may further include two steel strips 17, where the two steel strips 17 may be respectively fixed on two opposite edges of the flexible display screen 14 and may extend in a direction from the first end 14A to the second end 14B of the flexible display screen 14.
Specifically, the steel strip 17 may be made of a high elastic modulus material, for example, stainless steel or other metal materials. The thickness of the steel strip 17 may be 0.2mm or more. The width of the steel strip 17 may be defined according to the size of the flexible display 14, which is not limited by the present application. It will be appreciated that the steel strip 17 can strengthen the supporting strength of the flexible display screen 14, so as to avoid the flexible display screen 14 from being distorted during the unfolding process of the flexible display screen 14, thereby avoiding the flexible display screen 14 from being damaged, and the steel strip 17 can also play a role of lifting and supporting, so that the flexible display screen 14 can be unfolded and pulled out smoothly, and can be stored and pushed smoothly.
In some embodiments, as shown in fig. 4, 10 and 11, the display device 10 may further include a balance rail 18, where one end of the balance rail 18 may be connected to one end of one steel strip 17 extending to the second end 14B of the flexible display screen 14, and the other end of the balance rail 18 may be connected to one end of the other steel strip 17 extending to the second end 14B of the flexible display screen 14. In one example, both ends of the balance rail 18 may be vertically connected to ends of the two steel strips 17 extending to the second end 14B of the flexible display 14, respectively. Further, by fixedly connecting the two steel strips 17 with the balance rail 18, the problem of the flexible display screen 14 being distorted by the stretching operation during the expansion of the flexible display screen 14 can be further avoided.
In some embodiments, as shown in fig. 4 and 12, the display device 10 may further include a slide rail 19 and a slide rail cover 20, where the slide rail 19 may be fixed to the bottom case 11 by the slide rail cover 20. When the flexible display 14 is in the storage state, a portion of the flexible display 14 located between the first slide cover 12 and the bottom case 11 (i.e., the second end 14B) may abut against a side of the slide rail 19 facing away from the bottom case 11. Accordingly, the frictional resistance during the deployment of the flexible display 14 can be reduced, and the frictional resistance applied to the second end 14B of the flexible display 14 when pulled out can be reduced, so that the flexible display 14 can be more smoothly deployed and pulled out and stowed.
In some embodiments, as shown in fig. 4, 10 and 11, the display device 10 may further include a roller 21, the roller 21 may be fixed on the bottom case 11, and a rotation axis of the roller 21 may be perpendicular to a sliding direction of the second sliding cover 13. Specifically, the flexible display 14 may further include a middle portion 14C connecting the first end portion 14A and the second end portion 14B. When the flexible display 14 is in the storage state, the roller 21 may be positioned between the middle portion 14C of the flexible display 14 and the first slide cover 12, and the middle portion 14C of the flexible display 14 may abut against the roller 21. Accordingly, the frictional resistance during the unfolding of the flexible display 14 can be further reduced, so that the second end 14B of the flexible display 14 can be unfolded, pulled out and stored more smoothly.
In the above embodiment, as shown in fig. 13, the flexible display screen 14 may include a polarizer 141, a display layer 142, a flexible process support film 143, a screen structure support film 144, and a driving circuit, where the display layer 142 is disposed on one side of the polarizer 141, the flexible process support film 143 is disposed on one side of the display layer 142 away from the polarizer 141, the screen structure support film 144 is disposed on one side of the flexible process support film 143 away from the display layer 142, the driving circuit is electrically connected with the display layer 142, and in one example, the driving circuit may include a flexible circuit board (cof) 145 and a driving PCB 146, and the flexible circuit board (cof) 145 is used to electrically connect the driving PCB 146 to the display layer 142.
Specifically, the display layer 142 may be a flexible display layer such as an OLED display layer, the display layer 142 may include a substrate, an anode layer, an organic light emitting layer, a cathode layer, and a packaging layer, and the packaging layer may include a barrier layer and a buffer layer, and may prevent the film layers such as the organic light emitting layer from being damaged by environmental factors and external forces. The flexible process support film 143 may be made of foam, copper foil, graphite, etc., so as to achieve the functions of support, heat dissipation and anti-interference. The screen structure supporting film 144 may be made of polyurethane, so as to support and protect the display layer 142.
It should be noted that, the present embodiment provides a new application mode of the flexible display screen 14, and provides a new whole application mode by combining the flexible display screen 14 with the folding mode through the sliding roll, so that the flexible display screen 14 can not only utilize the display function of the flexible display screen 14, but also achieve the purpose of portability with respect to the curling after being stored, and can be restored to a conventional portable display device, such as a tablet computer or a handwriting pad, and when the unfolding function of the flexible display screen 14 is used, the display area can be optionally adjusted according to the requirement of a user, and further, after the flexible display screen 14 is completely unfolded, the display device 10 can be folded through an internal rotating shaft device (such as the rotating shaft 16) so as to be used as a conventional folding notebook.
As can be seen from the above, the display device provided in this embodiment includes: a bottom case; the first sliding cover is fixed on the bottom shell; the second sliding cover is in sliding connection with the first sliding cover; a flexible display screen including opposed first and second ends having a stowed condition, an extended condition, and a collapsed condition; when the flexible display screen is in a storage state, the first sliding cover and the second sliding cover are arranged in a stacked mode, the first end portion is located at one side, away from the first sliding cover, of the second sliding cover, and the second end portion is stored between the first sliding cover and the bottom shell; when the flexible display screen is switched from the storage state to the unfolding state, the first end part and the second sliding cover slide together relative to the first sliding cover so as to bring the second end part out to one side of the first sliding cover, which is away from the bottom shell; when the flexible display screen is switched from the unfolded state to the folded state, the first end part and the second sliding cover move together in a direction approaching to the second end part.
