Description

Technical Field

[0001] The present invention relates to a display panel. Specifically, the present invention relates to a display panel including a fixing member having a predetermined curvature. Background Art

[0002] In recent years, due to reasons such as improving the wrapping feeling or applying to non-planar installation surfaces, the application of curved display devices or non-planar display devices has gradually emerged. In order to realize a curved display device or a non-planar display device, it is necessary to design, develop, and manufacture each component of the display device having a predetermined curvature. However, if each component included in the display device is individually designed, developed, and manufactured to have a predetermined curvature, it will increase the manufacturing cost, manufacturing procedures, and manufacturing complexity. For example, it is necessary to open a plurality of molds with predetermined curvatures for different components. As described above, this increased cost, procedures, and complexity also make it difficult to develop display devices for various predetermined curvatures, or increase the threshold for realizing display devices with different predetermined curvatures. Therefore, in order to realize more diverse curved display devices or non-planar display devices, it is necessary to develop structures or processes that can reduce costs, procedures, and complexity, so as to more flexibly realize display devices for different predetermined curvatures that may be required. Summary of the Invention

[0003] To solve the above problems, according to an embodiment of the present invention, a display panel is provided, which includes: a backplane, having flexibility, having a bottom plate, and the bottom plate has a first side edge; a first fixing member, extending corresponding to the first side edge and having a first predetermined curvature, the first fixing member at least has a first wall body, the first wall body stands upright relative to the bottom plate, and is fixedly connected to the backplane, so that the backplane adjusts the curvature relative to the first fixing member; a front frame, having flexibility, extending corresponding to the periphery of the backplane and being fixedly connected to the backplane, so that the curvature of the front frame is relatively adapted to the curvature of the backplane; and a display module, disposed between the backplane and the front frame.

[0004] According to the display panels provided by the embodiments of the present invention, the curvature of other components can be adjusted correspondingly based on at least one fixing member, and thus a display panel with various curvatures can be realized with a simple structure. As described above, according to the embodiments of the present invention, display panels with different curvatures can be realized by matching fixing members with different curvatures, and the need to pre-develop or prepare other components with predetermined curvatures can be reduced or avoided. For example, the need to pre-open molds with different curvatures for other components can be reduced or avoided. Therefore, when applied to a curved display device or a non-planar display device, according to the embodiments of the present invention, more diverse changes in predetermined curvatures can be realized with lower manufacturing costs, manufacturing procedures, and manufacturing complexity. Thereby, various curved display devices or non-planar display devices with predetermined curvatures can be prepared more flexibly according to requirements. Brief Description of the Drawings

[0078] Various embodiments will be described below. Those of ordinary skill in the art should be able to easily understand the spirit and principles of the present invention with reference to the description in conjunction with the drawings. However, although some specific embodiments will be specifically described in the text, these embodiments are only illustrative and are not considered restrictive or exhaustive in all aspects. In addition, the proportions and relative proportions of the components shown in the drawings may be exaggerated or varied for the sake of clear display and simplicity. Therefore, for those of ordinary skill in the art, various changes and modifications to the present invention should be obvious and easily achievable without departing from the spirit and principles of the present invention.

[0079] Refer to Figure 1 , according to an embodiment of the present invention, a display panel 10 is provided, which includes a backplane 200, a first fixing member 310, a front frame 600, and a display module 500 disposed between the backplane 200 and the front frame 600. Continuing from the above, the display module 500 can be any module that can perform display or emit light, and the backplane 200 and the front frame 600 can support, protect, or position the display module 500. In addition, according to other embodiments of the present invention, other modules, devices, or components commonly found in display panels can be provided, and those of ordinary skill in the art should understand their possible settings and variations.

[0080] Specifically, the backplane 200 may at least have a bottom plate 205. For example, refer to Figure 1 , the bottom plate 205 can be a rectangular plate, and its periphery P generally has a first side S1 and a second side S2 extending along a first direction D1, and a third side S3 and a fourth side S4 extending along a second direction D2. However, this is only an example. According to other embodiments of the present invention, it is not limited thereto, and the bottom plate 205 can be a plate of any shape and can be configured to carry, protect, or position the modules, devices, or components in the display panel 10.

[0081] According to this embodiment, the first fixing member 310 can be disposed corresponding to the side of the backplane 200. For example, the first fixing member 310 can be disposed on the side of the bottom plate 205 facing the display module 500 or the front frame 600 and can extend corresponding to the first side S1. Continuing from the above, the first fixing member 310 can have a first predetermined curvature C1. According to some embodiments, the center of the first predetermined curvature C1 can be located on the side of the bottom plate 205 facing the display module 500 or the front frame 600.

[0082] Continuing from the above, the first fixing member 310 may at least have a first wall 312. The above-mentioned first wall 312 may be a strip-shaped wall structure extending along the side. In the assembled state, the first wall 312 stands upright relative to the bottom plate 205 and is fixedly opposed to the back plate 200 along the first side S1 of the back plate 200.

[0083] Specifically, the back plate 200 may have flexibility that is prone to bending, concave curving, or deformation relative to the first fixing member 310. For example, the back plate 200 may have a Young's modulus smaller than that of the first fixing member 310. Therefore, the flexible back plate 200 with flexibility can adjust its curvature relative to the first fixing member 310. For example, the first fixing member 310 may be made of a metal material such as but not limited to iron and may be integrally formed, while the back plate 200 may be made of a polyimide material softer than the metal material and have slots. Thereby, the back plate 200 can be easily bent and concave-folded relative to the first fixing member 310. However, this is only an example, and according to other embodiments of the present invention, the manner or aspect in which the flexibility of the back plate 200 or the frame and the front frame 600 described later is higher than that of the fixing member is not limited to this.

[0084] Continuing from the above, referring to Figure 2 and Figure 3 , the flexible back plate 200 that originally did not have the first predetermined curvature C1, when fixed to the first fixing member 310 along the first side S1, will bend, concave-fold, or deform in accordance with the first fixing member 310, thereby having a curvature or shape corresponding to the first predetermined curvature C1 of the first fixing member 310.

[0085] According to this embodiment, the front frame 600 may be provided corresponding to the periphery P of the back plate 200 and may have flexibility similar to that of the back plate 200, which is prone to bending, concave curving, or deformation relative to the first fixing member 310. For example, the front frame 600 may have a Young's modulus smaller than that of the first fixing member 310. Thereby, as Figure 2 shown, when the front frame 600 is fixed relative to the back plate 200, the front frame 600 can deform K in accordance with the shaped back plate 200. Therefore, as Figure 3 shown, in the case of relative assembly and fixation, the curvature of the front frame 600 can be relatively adapted to the curvature of the back plate 200.

[0086] According to some embodiments, after being relatively fixed to the first fixing member 310, the back plate 200 may also have a first predetermined curvature C1, and after the front frame 600 is relatively fixed to the back plate 200 and even the first fixing member 310, the front frame 600 may also have the first predetermined curvature C1. However, the present invention is not limited thereto, and due to the influence of the thickness during assembly and other modules, devices or components provided in the middle, the back plate 200 and the front frame 600 may also have curvatures corresponding to the change of the first predetermined curvature C1 but not completely equal to the first predetermined curvature C1. As mentioned above, those with ordinary knowledge in the technical field should understand the changes of these tolerances, and will not be elaborated herein.

[0087] For the convenience of display and description, the above Figures 1 to 3 is a schematic diagram showing at least partial separation and disassembly of the back plate 200, the first fixing member 310, the display module 500, and the front frame 600. In addition, the display module 500 may be a module integrated by many devices or components for display, rather than simply referring to a single plate-like component. Therefore, individual devices or components in the display module 500 may be deformed or may not be deformed relative to the molded back plate 200 and the front frame 600. As mentioned above, those with ordinary knowledge in the technical field should understand the changes thereof, and will not be elaborated herein.

[0088] Next, refer to Figure 4 , which shows a cross-sectional schematic diagram taken along the section line X-X' of the display panel 10 of Figure 3 . According to an embodiment, the back plate 200, the first fixing member 310, the display module 500, and the front frame 600 can be relatively fixed by any existing or future-developed means, such as screwing, colloidal adhesion, hooks, welding, etc., and this should be understood by those with ordinary knowledge in the technical field, and will not be elaborated herein. As mentioned above, according to this embodiment, in the complete assembly, the first fixing member 310 can be arranged vertically on the bottom plate 205 of the back plate 200, and the front frame 600 can be relatively arranged to cover the bottom plate 205 and the first fixing member 310. For example, the front frame 600 can cover the outer wall surface of the first wall 312 of the first fixing member 310 along the first side S1. Therefore, according to this embodiment, relative fixing and curvature adjustment can be achieved with a relatively simple structure, and the first wall 312 of the first fixing member 310 is used to replace the side wall portion of the existing back plate 200, thereby reducing the manufacturing cost and the thickness of the display panel 10.

[0089] According to other embodiments of the present invention, the forms and assembly forms of the back plate 200 and the front frame 600 that can be paired with the first fixing member 310 are not limited thereto. For example, the front frame 600 may also cover the top wall surface of the first wall body 312 of the first fixing member 310 along the first side S1, or cover the side wall portion 210 protruding from the bottom plate 205 of the back plate 200 along the first side S1, etc. Continuing from the above, more forms will be further described below, and those with ordinary knowledge in the technical field will understand more variations applicable to the present invention therefrom.

[0090] Continuing from the above, with reference to Figure 5 and Figure 6 According to another embodiment of the present invention, the display panel 10 may actually further include a flexible frame 400. Among them, the frame 400 is arranged between the back plate 200 and the front frame 600 corresponding to the periphery P of the back plate 200. Based on this structure, different setting spaces can be further partitioned by the frame 400 to configure different modules, etc., and the display module 500 can be arranged, for example, between the front frame 600 and the frame 400. Continuing from the above, the flexible frame 400 can be relatively fixed to the back plate 200 or even the first fixing member 310. Therefore, similar to the above-mentioned front frame 600, the curvature of the flexible frame 400 can be relatively adapted to the curvature of the back plate 200.

[0091] In addition to adjusting the curvature by relatively fixing with the first fixing member 310, the relative configuration forms of these different front frames 600, frames 400, and back plates 200 should be understood by those with ordinary knowledge in the technical field, and will not be elaborated here.

[0092] Next, with reference to Figures 7A to 7J According to different embodiments of the present invention, the first fixing member 310 with different shapes and relative configuration forms can be set to adjust the curvature of the above-mentioned display panel 10. Continuing from the above, for the sake of simplicity and clarity, Figures 7A to 7J only the relative configuration of the first fixing member 310 and the back plate 200 will be shown.

[0093] As described above, with reference to Figure 7A According to the variation aspect T1, in addition to the bottom plate 205, the back plate 200 may further have a first side wall portion 210, and the first side wall portion 210 protrudes from the bottom plate 205 and stands upright at the first side S1. Among them, the inner wall surface F1 of the first wall body 312 of the first fixing member 310 can be attached to the outer wall surface A2 of the first side wall portion 210, thereby adjusting the curvature of the back plate 200 with the first fixing member 310. Continuing from the above, according to this embodiment, by simply attaching the wall-shaped first wall body 312 to the first side wall portion 210, relative fixing and curvature adjustment can be achieved in a relatively simplified form, and the stability of the display panel 10 can be further enhanced by the surface contact between the inner wall surface F1 and the outer wall surface A2.

[0094] Next, referring to Figure 7B , according to the variant aspect T2, which can be similar to the above-mentioned variant aspect T1, and the difference is that the outer wall surface F2 of the first wall body 312 of the first fixing member 310 can be attached to the inner wall surface A1 of the first side wall portion 210, thereby adjusting the curvature of the back plate 200 with the first fixing member 310. In this embodiment, the first side wall portion 210 of the back plate 200 and the bottom plate 205 define a chamber M, and the first wall body 312 of the first fixing member 310 is substantially disposed in the chamber M. Continuing from the above, the first wall body 312 of the first fixing member 310 abuts against the inner wall surface A1 of the first side wall portion 210 and the front surface B1 of the bottom plate 205 facing the display module. Therefore, according to this embodiment, relative fixation and curvature adjustment can be achieved in a relatively simplified form, and based on the fact that the first wall body 312 of the first fixing member 310 abuts against the inner wall surface A1 of the first side wall portion 210 of the back plate 200 and the front surface B1 of the bottom plate 205 at the same time, the curvature change of the back plate 200 can be adjusted more precisely, and unexpected deformation of the back plate 200 can be avoided.

[0095] Next, referring to Figure 7C , according to the variant aspect T3, the difference from the above-mentioned variant aspect T1 is that the first fixing member 310 may further have a cover plate 314 connected to the first wall body 312 and a first opposing wall body 316 connected to the cover plate 314. Specifically, the cover plate 314 can cover and stack on the top surface A3 of the first side wall portion 210, and the first wall body 312 and the first opposing wall body 316 protrude from both sides of the cover plate 314 and stand downwards corresponding to the outer wall surface A2 and the inner wall surface A1 of the first side wall portion 210 respectively. Continuing from the above, the inner wall surface F1 of the first wall body 312 and the outer wall surface F2' of the first opposing wall body 316 are respectively attached to the outer wall surface A2 and the inner wall surface A1 on the opposite sides of the first side wall portion 210. Thereby, according to this embodiment, the first side wall portion 210 can be clamped by the first fixing member 310, and further the first opposing wall body 316 abuts against the inner wall surface A1 of the first side wall portion 210 of the back plate 200 and the front surface B1 of the bottom plate 205 at the same time, so as to more stably maintain the expected curvature of the back plate 200 and avoid unexpected deformation of the back plate 200.

[0096] Next, continue to refer to Figure 7D, according to the variation pattern T4, the backplane 200 may only have the bottom plate 205 without the first side wall portion 210. Continuing from the above, according to this embodiment, the first fixing member 310 may have a first wall body 312 and a supporting portion 315 connected to the first wall body 312, and the first wall body 312 protrudes relative to the supporting portion 315 and stands upright. Among them, the first wall body 312 can replace the first side wall portion 210 of the backplane 200 as the support of the side wall, and the supporting portion 315 is arranged along the first side S1 and adheres to at least a part of the bottom surface B2 of the bottom plate 205 facing away from the display module. Therefore, according to this embodiment, the first wall body 312 can be used as the support of the side wall to reduce the setting of the first side wall portion 210, thereby reducing the materials used and the thickness of the overall structure, and the curvature change of the backplane 200 can be maintained by the bottom plate 205 abutting against the first wall body 312 and the supporting portion 315 at the same time.

[0097] Furthermore, referring to Figure 7E , according to another variation pattern T5, the difference from the variation pattern T4 is that the backplane 200 has the first side wall portion 210. Continuing from the above, according to this embodiment, the supporting portion 315 is arranged along the first side S1 and adheres to at least a part of the bottom surface B2 of the bottom plate 205, and the inner wall surface F1 of the first wall body 312 can be attached to the outer wall surface A2 of the first side wall portion 210, thereby adjusting the curvature of the backplane 200 with the first fixing member 310. Therefore, according to this embodiment, by attaching the wall-shaped first wall body 312 to the first side wall portion 210 and further supporting the bottom plate 205 by the supporting portion 315, the curvature change of the backplane 200 can be further stabilized and maintained.

[0098] Similarly, referring to Figure 7F , according to yet another variation pattern T6, the difference from the variation pattern T5 is that the first fixing member 310 is arranged in the chamber M defined by the first side wall portion 210 and the bottom plate 205. Continuing from the above, according to this embodiment, the supporting portion 315 is arranged along the first side S1 and adheres to at least a part of the front surface B1 of the bottom plate 205, and the outer wall surface F2 of the first wall body 312 can be attached to the inner wall surface A1 of the first side wall portion 210, thereby adjusting the curvature of the backplane 200 with the first fixing member 310. Therefore, according to this embodiment, by attaching the wall-shaped first wall body 312 to the first side wall portion 210 and making the first side wall portion 210 and the bottom plate 205 abut against the first wall body 312 and the supporting portion 315 of the first fixing member 310 in the inner direction where the backplane 200 is prone to unexpected deformation at the same time, the curvature change of the backplane 200 can be further strengthened and maintained.

[0099] Furthermore, the above-mentioned various implementation patterns can also be combined and varied. For example, referring to Figure 7G, according to a variation pattern T7, relative to the above-mentioned variation pattern T6, in addition to having the first wall body 312 and the supporting part 315 connected to the first wall body 312, the first fixing member 310 may further have a first opposing wall body 316 separated from the first wall body 312 and the supporting part 315. Specifically, the supporting part 315 may be disposed along the first side S1 and attached to at least a part of the front surface B1 of the bottom plate 205, and the outer wall surface F2 of the first wall body 312 and the inner wall surface F1' of the first opposing wall body 316 may be attached to the inner wall surface A1 and the outer wall surface A2 of the first side wall part 210 respectively. Therefore, according to this embodiment, when space and cost permit, the curvature change of the back plate 200 can be further strengthened and maintained by jointly implementing the setting methods of different pattern parts of the first fixing member 310.

[0100] Similarly, referring to Figure 7H , according to a variation pattern T8, relative to the above-mentioned variation pattern T5, in addition to having the first wall body 312 and the supporting part 315 connected to the first wall body 312, the first fixing member 310 may further have a first opposing wall body 316 separated from the first wall body 312 and the supporting part 315. Specifically, the supporting part 315 may be disposed along the first side S1 and attached to at least a part of the bottom surface B2 of the bottom plate 205, and the inner wall surface F1 of the first wall body 312 and the outer wall surface F2' of the first opposing wall body 316 may be attached to the outer wall surface A2 and the inner wall surface A1 of the first side wall part 210 respectively. Therefore, according to this embodiment, when space and cost permit, the curvature change of the back plate 200 can be further strengthened and maintained by jointly implementing the setting methods of different pattern parts of the first fixing member 310.

[0101] Furthermore, referring to Figure 7I , according to yet another variation pattern T9, the first fixing member 310 may also be set in a form similar to the combination of the above-mentioned variation patterns T1 and T2. Specifically, relative to the above-mentioned variation pattern T2, in addition to the first wall body 312 abutting against the inner wall surface 210 of the first side wall part 210, the first fixing member 310 of this embodiment may further have a first opposing wall body 316 disposed outside the first side wall part 210 and abutting against the outer wall surface A2 of the first side wall part 210. Therefore, according to this embodiment, when space and cost permit, the curvature change of the back plate 200 can be further strengthened and maintained by jointly implementing the setting methods of different pattern parts of the first fixing member 310.

[0102] Next, according to Figure 7J, according to another variant T10, the first fixing member 310 can be arranged in a form similar to the combination of the above-mentioned variants T5 and T6. Specifically, compared with the above-mentioned variant T6, in addition to the first wall 312 abutting against the inner wall surface A1 of the first side wall portion 210 and the supporting portion 315 abutting against the front surface B1 of the bottom plate 205, the first fixing member 310 of this embodiment can further have a first opposing wall 316 arranged outside the first side wall portion 210 to abut against the outer wall surface A2 of the first side wall portion 210, and further have a supporting portion 319 connected to the first opposing wall 316 to abut against the back surface B2 of the bottom plate 205. Therefore, according to this embodiment, when space and cost permit, the curvature change of the back plate 200 can be further strengthened and maintained by jointly implementing the setting methods of different component variants of the first fixing member 310.

[0103] As described above, according to the embodiments of the present invention, the curvature of other flexible components can be adjusted by simply arranging the first fixing member 310 with a predetermined curvature, thereby realizing display panels with various curvatures. Therefore, only different fixing members need to be prepared for a predetermined curvature, so that it is possible to reduce or avoid the need to open molds or processes with different curvatures for each component, and more diverse curvature changes of display panels can be achieved based on components produced by the same process.

[0104] According to some embodiments of the present invention, the first fixing member 310 that is fixedly arranged along the first side S1 of the bottom plate 205 and extends to correspondingly adjust the curvature of the back plate 200 can have a fixed first predetermined curvature C1. However, the present invention is not limited thereto. For example, the first predetermined curvature of the first fixing member 310 described in the above embodiments can also vary along the first side S1. For example, referring to Figure 8 , the first fixing member 310 can have different first predetermined curvatures C1 and C1' along the first side S1 where the curvature is to be adjusted. Therefore, more refined and rich curvature changes of the display panel can be achieved by means of the first fixing member 310, and it can be applied to a wider range of scenarios or occasions. For example, such a display panel can be installed on a wall with a non-uniform curvature or at a wall turning point for display.

[0105] In addition, further referring to Figure 9, according to another embodiment of the present invention, the display panel 20 may substantially include a plurality of first fixing members 310 sequentially arranged along the first side S1. For example, the plurality of first fixing members 310 may be spaced apart on the first side S1, and the extending direction is substantially parallel to the arrangement direction of the plurality of first fixing members 310, or substantially parallel to the extending direction of the first side S1 with a correspondingly changed curvature. Continuing from the above, the above-mentioned first fixing members 310 may have the same or different first predetermined curvatures. Thereby, the material used for arranging the first fixing members 310 or the thickness of the device can be reduced based on the spaced-apart arrangement of the plurality of first fixing members 310. In addition, the curvatures of other components such as the backplane 200 at different local parts can also be adjusted respectively based on the different plurality of first fixing members 310.

[0106] Similarly, referring to Figure 10 , according to another embodiment of the present invention, the display panel 30 may also include a plurality of first fixing members 310 sequentially arranged along the first side S1 similar to the above-mentioned display panel 20. For example, the above-mentioned plurality of first fixing members 310 in the display panel 30 may be configured to be closely connected, and the extending direction is substantially parallel to the arrangement direction of the plurality of first fixing members 310, or substantially parallel to the extending direction of the first side S1 with a correspondingly changed curvature. Continuing from the above, the above-mentioned first fixing members 310 may have the same or different first predetermined curvatures. For example, the first predetermined curvature C1' and the first predetermined curvature C1. Thereby, the curvatures of other components such as the backplane 200 at different local parts can be precisely adjusted in detail based on the closely arranged plurality of first fixing members 310.

[0107] In the aspects of the above embodiments, the first fixing members 310 are arranged on the first side S1 to adjust the curvature of the display panel. However, according to other embodiments of the present invention, fixing members may also be arranged on other sides to adjust the curvature of the display panel. For example, fixing members may be arranged only on the second side S2, the third side S3, or the fourth side S4. Another example is that if the bottom plate 205 has an expected shape different from a rectangle, fixing members may also be arranged on any side corresponding to the expected shape to adjust the curvature of the display panel. Continuing from the above, those skilled in the art should be able to understand the setting method and possible variation aspects from the above description, and will not be elaborated here.

[0108] Furthermore, according to other embodiments of the present invention, fixing members may also be arranged on different sides. For example, referring to Figure 11, according to yet another embodiment of the present invention, in the display panel 40, the bottom plate 205 has a second side S2 that faces the first side S1 and is not connected thereto, and fixing members can be provided on both the first side S1 and the second side S2. Specifically, on the first side S1 of the display panel 40, a first fixing member 310 can be provided as described in the above other embodiments, and a second fixing member 320 can be further provided on the second side S2.

[0109] Continuing from the above, the second fixing member 320 can extend corresponding to the second side S2 and have a second predetermined curvature C2. Refer to Figure 12 , similar to the first fixing member 310, the second fixing member 320 can at least have a second wall body 322. The second wall body 322 can stand upright relative to the bottom plate 205 and be fixedly opposed to the back plate 200, enabling the back plate 200 to adjust the curvature relative to the second fixing member 320. For example, the first wall body 312 of the first fixing member 310 and the second wall body 322 of the second fixing member 320 can respectively abut against the inner wall surfaces of the first side wall portion 210 and the second side wall portion 220 of the back plate 200 along the first side S1 and the second side S2. However, the form and arrangement of the second fixing member 320 according to other embodiments of the present invention are not limited to this. Continuing from the above, except for the different sides where they are provided, the second fixing member 320 can be similar to the first fixing member 310 and have various setting methods and variation patterns, and this should be understandable and deduced with reference to the above.

[0110] In addition, according to some embodiments, the second predetermined curvature C2 can be the same as or different from the first predetermined curvature C1 to adjust the curvature for different sides of the bottom plate 205 respectively.

[0111] As described above, by using fixing members with greater rigidity such as the first fixing member 310 or the second fixing member 320, the curvatures of the flexible back plate 200, the front frame 600, and the frame 400 can be adjusted accordingly. The above flexible back plate 200, front frame 600, and frame 400 can be implemented in various ways or forms. For example, materials with high flexibility such as polyimide (PI) can be used to make the back plate 200, the front frame 600, and the frame 400. Additionally, corresponding structures can also be designed in parts that are difficult to bend and fold. For example, refer to Figure 13A , a side wall portion of the back plate 200, such as the first side wall portion 210 that protrudes and stands upright along the first side S1, can have a plurality of slots H, such that the first side wall portion 210 extends discontinuously opposite the top surface A3 of the bottom plate.

[0112] Similarly, refer to Figure 13B, according to different embodiments, the front frame 600 may have a top frame portion 605 facing the bottom plate surface of the back plate, side frame portions 610 erected relative to the bottom plate, or a combination thereof. Continuing from the above, the top frame portion 605, the side frame portions 610, or a combination thereof may also have a plurality of slots H' along the first side S1, such that the edge of the front frame 600 extends discontinuously along the first side S1.

[0113] Continuing from the above, referring to Figure 13C , the selectively provided frame 400 may also have a similar structure. Specifically, the frame 400 may also have a plurality of slots H" along the first side S1, such that the edge of the frame 400 extends discontinuously along the first side S1.

[0114] As described above, in the case where it is expected to provide a fixing member along the first side S1 and the back plate 200, the frame 400, and the front frame 600 are adjusted correspondingly, a plurality of slots H, H', and H" may be provided in the back plate 200, the frame 400, and the front frame 600 along the first side S1. Therefore, the flexibility of the back plate 200, the frame 400, and the front frame 600 along the first side S1 can be improved. Specifically, as Figure 14A and Figure 14B shown, in the case of having the slots H, H', and H", the back plate 200, the frame 400, and the front frame 600 can be more easily bent, concave-folded, or deformed N. Thereby, the curvature can be adjusted more easily in cooperation with a fixing member having a relatively high rigidity and a predetermined curvature. Continuing from the above, according to some embodiments, a part of the component having the slots H, H', and H" can be laminated with the fixing member after being bent and concave-folded in cooperation with the fixing member, such that the fixing member overlaps the slots H, H', and H", thereby fixing the curvature and avoiding unexpected deformation at the slots H, H', and H". However, the above methods or structures for making the back plate 200, the frame 400, and the front frame 600 flexible are only examples, and the present invention is not limited thereto.

[0115] Furthermore, in addition to the above fixing members mainly fixed relative to the back plate 200, according to other embodiments of the present invention, fixing members mainly fixed relative to the front frame 600 may be further provided. For example, referring to Figure 15 , the display panel 50 may have a back plate 200, a frame 400, a display module 500, and a front frame 600. Among them, corresponding to the first side S1, as described above, there is a first fixing member 310 fixed relative to the back plate 200. However, according to this embodiment, it may further include a first auxiliary fixing member 310' extending corresponding to the first side S1 and having a first predetermined curvature corresponding to the first fixing member 310. Continuing from the above, the first auxiliary fixing member 310' may at least have a first auxiliary wall body 312' erected relative to the bottom plate 205 and fixed relative to the front frame 600. Thereby, the front frame 600 can adjust the curvature relative to the first auxiliary fixing member 310', and thus the shaping of the predetermined curvature of the display panel 50 can be further improved and stabilized.

[0116] Next, some embodiments will be further described with reference to Figures 16A to 16H illustrate the forms and relative arrangement relationships between the first auxiliary fixing member 310' and the front frame 600. In these figures, for clarity and conciseness, except for the first auxiliary fixing member 310' and the front frame 600, only the relative positions of the bottom plate 205 of the back plate will be schematically shown as a reference, and other components will be omitted.

[0117] As described above, as in Figure 16A and Figure 16B shown, according to the variation modes Z1 and Z2, the front frame 600 may have a top frame portion 605 facing the bottom plate 205 and a side frame portion 610 erected relative to the bottom plate 205 along the first side S1. In addition, the first auxiliary fixing member 310' may have a first auxiliary wall 312' disposed along the side frame portion 610.

[0118] Among them, in Figure 16A the variation mode Z1 shown, the inner wall surface Q1 of the first auxiliary wall 312' of the first auxiliary fixing member 310' is attached to the outer wall surface A2' of the side frame portion 610. Therefore, according to this embodiment, relative fixation and curvature adjustment can be achieved in a relatively simplified form.

[0119] In addition, in Figure 16B the variation mode Z2 shown, the outer wall surface Q2 of the first auxiliary wall 312' of the first auxiliary fixing member 310' is attached to the inner wall surface A1' of the side frame portion 610. That is, the first auxiliary wall 312' is attached to the inner wall surface A1' on the side of the side frame portion 610 facing the center of the bottom plate 205. Therefore, according to this embodiment, relative fixation and curvature adjustment can be achieved in a relatively simplified form, and based on the fact that the first auxiliary wall 312' of the first auxiliary fixing member 310' abuts against both the side frame portion 610 and the top frame portion 605 of the front frame 600 at the same time, the curvature change can be adjusted more precisely, and unexpected deformation of the front frame 600 can be avoided.

[0120] Next, as in Figure 16C and Figure 16D shown, according to the variation modes Z3 and Z4, the front frame 600 may have a side frame portion 610 erected relative to the bottom plate 205 and a top frame portion 605 protruding from the end of the side frame portion 610 opposite to the bottom plate 205 to face the bottom plate 205 along the first side S1. In addition, the first auxiliary fixing member 310' has a first auxiliary wall 312' and a top plate 315' connected to the first auxiliary wall 312' and protruding relative to the first auxiliary wall 312' to face the bottom plate 205.

[0121] Among them, in Figure 16CIn the shown deformation state Z3, the inner wall surface Q1 of the first auxiliary wall 312' of the first auxiliary fixing member 310' is attached to the outer wall surface A2' of the side frame portion 610. Additionally, the wall surface, i.e., the back surface R2 of the top plate 315' of the first auxiliary fixing member 310' is attached to the wall surface, i.e., the front surface B1' of the top frame portion 605. Therefore, according to this embodiment, by attaching the wall-shaped first auxiliary wall 312' to the side frame portion 610 and further supporting the top frame portion 605 by the top plate 315', the curvature change of the front frame 600 can be further stabilized and maintained.

[0122] In addition, in Figure 16D In the shown deformation state Z4, the outer wall surface Q2 of the first auxiliary wall 312' of the first auxiliary fixing member 310' is attached to the inner wall surface A1' of the side frame portion 610. Additionally, the wall surface, i.e., the front surface R1 of the top plate 315' of the first auxiliary fixing member 310' is attached to the wall surface, i.e., the bottom surface B2' of the top frame portion 605. That is, the first auxiliary fixing member 310' is provided to abut against the wall surface of the front frame 600 facing the bottom plate 205. Therefore, according to this embodiment, by attaching the wall-shaped first auxiliary wall 312' to the side frame portion 610 and by causing the side frame portion 610 and the top frame portion 605 to simultaneously abut against the first auxiliary wall 312' and the top plate 315' of the first auxiliary fixing member 310' in the inner direction where the front frame 600 is prone to unexpected deformation, the curvature change of the front frame 600 can be further strengthened, stabilized, and maintained.

[0123] As described above, when space and cost permit, the above various deformation states can also be combined to achieve more stable curvature adjustment.

[0124] For example, as Figure 16E shown, according to the deformation state Z5, the difference from the deformation state Z2 is that the first auxiliary fixing member 310' further has a first auxiliary opposite wall 316' separated from the first auxiliary wall 312'. Among them, the outer wall surface Q2 of the first auxiliary wall 312' and the inner wall surface Q1' of the first auxiliary opposite wall 316' can be respectively attached to the inner wall surface A1' and the outer wall surface A2' on the opposite sides of the side frame portion 610, such that the outer wall surface Q2' of the first auxiliary opposite wall 316' faces outward. Therefore, according to this embodiment, the curvature adjustment of the front frame 600 can be further stabilized with a simplified structure.

[0125] In addition, as Figure 16FAs shown, according to the variation pattern Z6, the difference from the variation pattern Z4 is that the first auxiliary fixing member 310' further has a first auxiliary opposite wall 316' separated from the first auxiliary wall 312', and a top plate 319' connected to the first auxiliary opposite wall 316'. Continuing from the above, the first auxiliary wall 312' and the top plate 315' of the first auxiliary fixing member 310' are arranged to abut against the wall surface of the front frame 600 facing the bottom plate 205. In contrast, the first auxiliary opposite wall 316' and the top plate 319' of the first auxiliary fixing member 310' are arranged to abut against the wall surface of the front frame 600 facing away from the bottom plate 205. Therefore, according to this embodiment, with the structures of the top plate 315' and the top plate 319', the curvature adjustment of the front frame 600 can be further strengthened and stabilized.

[0126] Next, as Figure 16G shown, according to the variation pattern Z7, the difference from the variation pattern Z6 is that it does not have a top plate 315' that is connected to the first auxiliary wall 312' and protrudes along the bottom surface B2' of the top frame portion 605. Therefore, according to this embodiment, under the condition of stabilizing the curvature adjustment of the front frame 600, the setting space defined inside the front frame 600 can be increased according to requirements.

[0127] In contrast, as Figure 16H shown, according to the variation pattern Z8, the difference from the variation pattern Z6 is that it does not have a top plate 319' that is connected to the first auxiliary opposite wall 316' and protrudes along the front surface B1' of the top frame portion 605. Therefore, according to this embodiment, under the condition of stabilizing the curvature adjustment of the front frame 600, the thickness increase on the front frame 600 can be reduced or avoided as needed, and the top plate 319' can be prevented from being observed from the front frame 600 during use, thereby improving or simplifying the appearance.

[0128] In summary, for the display panel according to the embodiments of the present invention, the predetermined curvature of other flexible components can be correspondingly adjusted based on the predetermined curvature of the fixing member arranged along the side. Therefore, it is possible to apply fixing members with different predetermined curvatures to achieve display panels with different predetermined curvatures without preparing components with a predetermined curvature. Therefore, with basic core components and different fixing members, diversified non-planar display panels or curved display panels can be realized at a significantly reduced manufacturing cost and pre-operation. Further, the curvature of the display panel to be set can be designed and changed more flexibly according to different setting environments and scenarios, thereby increasing the applicability and industrial property of the display panel.

[0129] The above are only some preferred embodiments of the present invention. It should be noted that the present invention can be variously changed and modified without departing from the spirit and principles of the present invention. Those of ordinary skill in the art should understand that the present invention is defined by the appended patent application scope, and various possible permutations, combinations, modifications, conversions, etc. that are in line with the spirit of the present invention do not exceed the scope defined by the appended patent application scope of the present invention.
