Description

Technical Field

[0001] This invention relates to a display device. More specifically, this invention relates to a display device having multiple main bodies and multiple elastic modules disposed on the back of a display module. Background Technology

[0002] In recent years, with the technological maturity of flexible display modules, these modules have gradually become widespread in various industries and daily life. As mentioned above, flexible display modules can have different display styles and offer greater operational freedom. However, to achieve flexible operation, these modules may incorporate space-consuming or bulky bending mechanisms such as supports, or unintentionally reduce the overall structural strength of the display module in an attempt to increase flexibility. Therefore, reducing the space or volume occupied while maintaining structural strength and operability has become a crucial issue in the development of such display modules. Furthermore, depending on the application environment or scenario, there is a desire to develop technologies that can further utilize the flexibility of display modules to achieve more diverse functions, thereby potentially allowing for integration with more objects or devices through changes in display styles to achieve the desired effects.

[0074] Various embodiments will be described below, and those skilled in the art should readily understand the spirit and principles of the invention by referring to the description and accompanying drawings. However, while specific embodiments will be described in detail herein, these embodiments are merely illustrative and are not intended to be limiting or exhaustive in any respect. Therefore, various changes and modifications to the invention will be readily apparent and easily achievable by those skilled in the art without departing from the spirit and principles of the invention.

[0075] Reference Figure 1 and along Figure 1 The section line X-X' intercepts Figure 2 According to an embodiment of the present invention, a display device 10 is provided, comprising: a display module 100 having a display surface B1 for display and an opposite back surface B2; a plurality of main bodies 200 arranged on the back surface B2 of the display module 100; a plurality of elastic modules Q respectively disposed between adjacent main bodies 200; a cable 300 extending through the main bodies 200; and a cable retractor 400 configured to retract the cable 300.

[0076] Specifically, according to this embodiment, the display module 100 may have opposing first sides S1 and second sides S2. The first side S1 may be relatively fixed, while the second side S2 may be an open, free end. Furthermore, the display module 100 may be flexible and at least partially bendable, and when the display module 100 is bent, the second side S2, which is not fixedly connected to other objects or devices, may have the freedom of movement. Furthermore, the main bodies 200 may be relatively rigid structural blocks and may serve as supports for the flexible display module 100 on its back surface B2. For example, the main bodies 200 may be made of ceramic or metal. Therefore, based on these main bodies 200, the overall structural stability and strength of the display module 100 can be increased, and unintended deformation or damage to the display module 100 during repeated bending or unfolding can be reduced or avoided.

[0077] According to some embodiments, such as Figure 2 As shown, the main body 200 may have a first side F1 facing the first side S1, a second side F2 facing the second side S2, and a through hole H extending from the first side F1 to the second side F2. The elastic modules Q may be respectively disposed between the first side F1 and the second side F2 of adjacent main bodies 200 to act as buffers between the main bodies 200 when the overall display module 100 flexes. As described above, the Young's modulus of the elastic modules Q may be smaller than the Young's modulus of the main bodies 200, so that the elastic modules Q have lower rigidity and can deform relatively to absorb or buffer stress and space compression during the flexing of the display module 100. For example, the elastic modules Q may be made of rubber or silicone. Based on this architecture, the display module 100 can maintain flexibility while improving stability and support, and the interference or collision that may occur between adjacent main bodies 200, which have higher rigidity as support structures, when the display module 100 flexes.

[0078] Furthermore, according to some embodiments, for example, each of the main bodies 200 may be substantially a body of a support unit P. For example, the display device 10 may have a plurality of support units P arranged sequentially from a first side S1 toward a second side S2 on the back surface B2 of the display module 100. For example, the support units P may be arranged adjacent to each other along a portion of the back surface B2 of the display module 100 that is expected to be bent. Each support unit P may include the aforementioned individual main body 200, and a first elastic body Q1 and a second elastic body Q2 respectively disposed on the first side F1 and the second side F2. Continuing with the above, in this exemplary embodiment, the elastic module Q may be composed of the first elastic body Q1 and the second elastic body Q2 of adjacent support units P. That is, the first elastic body Q1 of one of the support units P and the second elastic body Q2 of the other of the support units P may be disposed opposite each other. For example, refer to Figure 2 The elastic module Q may consist of a first elastic body Q1 of a support unit PA and a second elastic body Q2 of an adjacent support unit PB, wherein the Young's modulus of the first elastic body Q1 and the second elastic body Q2 may be less than the Young's modulus of the main body 200. For example, the first elastic body Q1 and the second elastic body Q2 may be made of rubber or silicone. In this embodiment, by the mutual compression deformation and release elasticity of the independent first elastic body Q1 and the second elastic body Q2, the buffer margin space between adjacent main bodies 200 during compression and release can be further increased. However, the elastic module Q is not limited to this example and may also be, for example, a one-piece molded, elastically deformable block, making the fabrication process of the elastic module Q simpler and faster; or it may be an elastic module Q in other combinations. Furthermore, when the elastic module Q has a Young's modulus less than the Young's modulus of the main body 200, the form of the elastic module Q can vary.

[0079] Next, continue to refer to Figure 2 According to some embodiments, the cable 300 can extend through a series of corresponding through holes H in the main bodies 200. Accordingly, the cable 300 may have a first end 301 and a second end 302 opposite to the first end 301 and positioned relative to a second side S2 of the display module 100. The cable 300 can slide back and forth along the series of corresponding through holes H in the support units P, and the cable retractor 400 can be positioned relative to the first side S1 of the display module 100 and configured to retract the cable 300 based on the first end 301. This allows the second side S2 of the display module 100 to be wound in conjunction with the movement of the second end 302.

[0080] For example, according to some embodiments, the display device 10 may further include a base 500, and the cable retractor 400 and the first side S1 of the display module 100 may both be fixed to the base 500. Additionally, the display device 10 may further include a bracket 600 disposed corresponding to the second side S2 of the display module 100, and protruding DT from the back surface B2 in a direction away from the display module 100, while the second end 302 of the cable 300 is limited by the bracket 600. Continuing on this, the fixed first side S1 of the display module 100 does not move when the display module 100 flexes, while the cable retractor 400, positioned relative to the fixed first side S1, can change the length of the cable 300 on the back surface B2 of the entire display module 100 by retracting or extending the cable 300 from the first end 301 of the cable 300. Since the second end 302 of the cable 300 is limited by the bracket 600 fixed relative to the second side S2 of the display module 100, the curvature of the display module 100 as a whole can change in response to the change in the length of the cable 300.

[0081] As described above, based on this architecture, the display module 100 of the display device 10 can be unfolded or flexed accordingly, and the unfolded or flexed display module 100 can also be used in conjunction with the shape or function of other objects or environments. For example, as Figure 1 As shown, the display module 100 can correspondingly flex and conform to the outline Cr of an object, and correspondingly reduce the space it may occupy when not in use. For example, the object may be a seat handle of a vehicle, and the display device 10 can be integrated into the seat handle for passengers to view when needed, but this is only an example and the objects that can be implemented are not limited to this. Furthermore, the display module 100 can relatively blend into the environment or object (and may even display the same or similar color or appearance as the environment or object for better integration), and only unfolds or flexes in the opposite direction when needed. Therefore, according to this embodiment, the applicable environment and operational flexibility of the display device 10 can be further expanded, and the space occupied by the display device 10 can be reduced or avoided.

[0082] Next, we will refer to the enlarged display of several support units P. Figure 3 And presenting the three-dimensional structure of one of the supporting units P. Figure 4 The above architecture will be described in further detail.

[0083] Continuing from above, refer to Figure 3According to this embodiment, each of the main bodies 200, when taken along the sequential arrangement direction DL of the main bodies 200, presents a columnar shape in cross-section M. For example, but not limited to, a trapezoidal columnar shape. Specifically, each of the main bodies 200 may have a bottom 201 connected to the back surface B2 and a top 202 opposite to the bottom 201, and in the columnar cross-section M, the width W2 of the top 202 may be smaller than the width W1 of the bottom 201. Furthermore, the bottom 201 of the main bodies 200 may be directly or indirectly connected to the back surface B2 by other connectors 205, such as a double-sided adhesive layer.

[0084] According to some embodiments, in each of these support units P, the first elastic body Q1 and the second elastic body Q2 are spaced apart from the bottom 201 and top 202 of the back surface B2 of the main body 200. This reduces or prevents the first elastic body Q1 and the second elastic body Q2 from becoming dislodged or misaligned from the end edges of the main body 200, such as the bottom 201 and top 202, or even squeezed out between adjacent main bodies 200 when compressed or released. Additionally, it ensures that the first elastic body Q1 and the second elastic body Q2 have more deformation buffer space while maintaining a sufficiently close distance to be compressed and released from each other.

[0085] Furthermore, according to some embodiments, in each of these support units P, a first elastic body Q1 and a second elastic body Q2 may be disposed between the back surface B2 and the through hole H. Hereby, the cable 300 passing through these through holes H can be positioned relatively closer to the top 202, allowing for easier force application with a longer lever arm from the back surface B2, and further limiting the deformation displacement of the first elastic body Q1 and the second elastic body Q2 in the direction DT. Therefore, the first elastic body Q1 and the second elastic body Q2 can reduce or prevent detachment or misalignment from the end edge of the main body 200, such as the top 202, or even extrusion between adjacent main bodies 200. Additionally, the absence of the first elastic body Q1 and the second elastic body Q2 at the end edge allows for more precise control of the overall flexural curvature of the display module 100, and makes the fabrication of the first elastic body Q1 and the second elastic body Q2 easier. Furthermore, the first elastic body Q1 and the second elastic body Q2, which are respectively disposed at the central positions of the first side F1 and the second side F2, can absorb and / or buffer the pressure stress of the entire body 200 more evenly, and can undergo the expected deformation. Therefore, the display module 100 can stably conform to the deformation of the first elastic body Q1 and the second elastic body Q2 when flexing, thereby absorbing and / or buffering the pressure stress, and can reduce or avoid misalignment of the components of the structure and increase the reliability and smoothness of repeated operation.

[0086] Next, along with Figure 3 Reference Figure 4The diagram shows that each of the main bodies 200 can extend substantially in a strip shape perpendicular to the arrangement direction DL. For example, each of the main bodies 200 can extend along the extension direction DE and cross the back surface B2 of the display module 100 to stably support the back surface B2 of the display module 100. Similarly, the first elastic body Q1 and the second elastic body Q2 can also be disposed on the first side surface F1 and the second side surface F2, respectively, along the extension direction DE. Furthermore, according to some embodiments, a first groove G1 can be formed on the first side surface F1 of each of the main bodies 200, and a second groove G2 can be formed on the second side surface F2. The first elastic body Q1 can be disposed in the first groove G1 and protrude from the first side surface F1 in the opposite direction to the main body 200, and the second elastic body Q2 can be disposed in the second groove G2 and protrude from the second side surface F2 in the opposite direction to the main body 200. This allows for better positioning of the first elastic body Q1 and the second elastic body Q2, and enables them to maintain better positioning even under mutual compression and pushing, thus reducing or preventing slippage along the first side F1 and the second side F2. Furthermore, it also allows for a further expansion of the buffer space for elastic deformation of the first elastic body Q1 and the second elastic body Q2, while ensuring that the distance between adjacent main bodies 200 is not too large and maintaining the stability and support of the display module 100.

[0087] Additionally, according to some embodiments, a plurality of through holes H may be substantially arranged along the extending direction DE for multiple cables 300 to pass through, and each cable 300 may have a relative configuration and structure relative to that described above for a single cable 300. Continuing on this, those skilled in the art should understand these configurations from the foregoing description, and will not be repeated here.

[0088] Next, we will refer to Figures 5 to 7 Further explanation is provided on how the display device 10 according to this embodiment implements the operation of the flexural display module 100.

[0089] As mentioned above, referring to Figures 5 to 7 According to some embodiments, the cable retractor 400 may be, for example, but not limited to, a cable winder, and may wind up the cable 300, for example, clockwise or counterclockwise. Continuing above, when the cable retractor 400 winds up the cable 300 along the winding direction DR, causing the second end 302 of the cable 300, which is relatively confined at the second side S2 of the display module 100, to be pulled along the winding direction DR, the second side S2 of the display module 100 will be pulled along with it, causing the entire display module 100 to coil.

[0090] As mentioned above, further refer to Figure 8 and Figure 9In contrast, when the cable retractor 400 extends the cable 300 to extend the display module 100, it can cause the first elastic body Q1 and the second elastic body Q2 of the adjacent support units P to spring apart and expand EE; while when the cable retractor 400 retracts the cable 300 to curl the display module 100, it can cause the first elastic body Q1 and the second elastic body Q2 of the adjacent support units P to compress and squeeze each other E.

[0091] Furthermore, according to this embodiment, such as Figure 8 As shown, when the cable retractor 400 releases the cable 300 to extend the display module 100 to its maximum extent, the first elastic body Q1 and the second elastic body Q2 of the adjacent support units P can still at least partially abut against each other. This ensures that the structural integrity and support strength of the back surface B2 of the display module 100 are maintained even when the display module 100 is extended to its maximum extent.

[0092] Next, we will refer to Figure 10 and Figure 11 The relative configuration and relative dimensions of the components of the display device 10 according to an embodiment of the present invention are described.

[0093] Continuing from above, refer to Figure 10 and Figure 11 Similar to the above, the display module 100 can simultaneously achieve flexibility and structural support based on the underlying body 200 and the elastic modules Q, such as the first elastic body Q1 and the second elastic body Q2, sandwiched between the bodies 200. Specifically, when the cable retractor 400 retracts the cable 300 to cause the display module 100 to bend to its maximum extent, the ends K2 of the bodies 200 of adjacent support units P facing away from the top 202 of the display module 100 can abut against each other. Therefore, the maximum flexibility of the display module 100 can be limited by the abutting of the ends K2 of the relatively rigid bodies 200, reducing or avoiding damage or deterioration of the display module 100 caused by unintended excessive bending or folding.

[0094] Furthermore, according to some embodiments, when the cable retractor 400 retracts the cable 300 to cause the display module 100 to bend to its maximum extent, the edges K1 of the main bodies 200 of adjacent support units P facing the bottom 201 of the display module 100 may also abut against each other. Therefore, the unintended extrusion or misalignment of the elastic modules Q, such as the first elastic body Q1 and the second elastic body Q2, when compressed to their maximum extent can be reduced or avoided, thereby increasing the overall stability of the flexed display module 100, and further limiting the maximum flexibility of the final display module 100, similar to the aforementioned edge K2. However, the above is merely an example, and in other embodiments of the present invention, where the edges K2 of adjacent top 202 may abut against each other when the display module 100 is curled to its maximum extent, the edges K1 of adjacent bottom 201 may not abut against each other.

[0095] Continuing from the above, with the end edges K2 abutting each other for limiting, the dimensions of each part of the main body 200 required to achieve the desired deflection curvature of the display module 100 can be derived accordingly. Specifically, along with... Figure 10 Reference Figure 11 When the cable retractor 400 retracts the cable 300 to connect with the curled display module 100, the tops 202 of the main bodies 200 of the support units P and the curvature center O of the display module 100 may have an inner curvature radius R. A predetermined sector angle θ is formed between one of the main bodies 200 closest to the first side S1 and one of the main bodies 200 closest to the second side S2 based on the curvature center O, and the number of main bodies 200 is N. In this case, in the cross-section M taken along the arrangement direction DL of each of the main bodies 200, the maximum width W2 of the tops 202 of the main bodies 200 is (θ / 180xπx R) / N.

[0096] Similarly, when the cable retractor 400 retracts the cable 300 to connect with the curled display module 100, the bottom 201 of the main bodies 200 of the support units P may have an outer radius of curvature R' from the curvature center O of the display module 100, and a predetermined sector angle θ is formed between one of the main bodies 200 closest to the first side S1 and one of the main bodies 200 closest to the second side S2 based on the curvature center O, and the number of these main bodies is N. In this case, in the cross section M taken along the arrangement direction DL of each of the main bodies 200, the maximum width W1 of the bottom 201 of the main bodies 200 is (θ / 180xπx R') / N.

[0097] Next, we will refer to Figure 12 and Figure 13Further explanation is provided regarding the specific configuration and state of the first elastomer Q1 and the second elastomer Q2 according to some embodiments of the present invention.

[0098] Continuing from above, refer to Figure 12 The adjacent support units P, specifically the first elastic body Q1 and the second elastic body Q2, may each have a corresponding meshing first structure V1 and a second structure V2. In detail, besides the first elastic body Q1 and the second elastic body Q2 facing each other and capable of corresponding pushing and squeezing, according to some embodiments, the first elastic body Q1 and the second elastic body Q2 may each have a first structure V1 and a second structure V2 whose shapes are mutually matched and can be correspondingly assembled.

[0099] For example, the first structure V1 and the second structure V2 may each have a first serrated structure V1' and a second serrated structure V2' arranged in a direction DT away from the display module 100. That is, in the thickness direction of the body 200 in the direction DT away from the display module 100, the first structure V1 and the second structure V2 may each have a continuous undulating first serrated structure V1' and a second serrated structure V2'. This further enhances the positioning of the first elastic body Q1 and the second elastic body Q2 when they push, squeeze, or spring apart. However, the above is merely an example, and the possible forms and shapes of the first structure V1 and the second structure V2 according to other embodiments of the present invention are not limited to the examples specifically shown herein, provided that the mutual positioning of the first elastic body Q1 and the second elastic body Q2 and the smoothness of their engagement, pushing, or pushing apart can be improved.

[0100] Furthermore, along with Figure 12 Refer to the enlarged schematic diagram showing the relative shapes of the first sawtooth structure V1' and the second sawtooth structure V2'. Figure 13According to some other embodiments, the individual serrations U1 and U2 of the first serration structure V1' and the second serration structure V2' may each have two asymmetrical sides ML relative to the apex MT of serrations U1 and U2, such that the individual serration of one of the first serration structure V1' and the second serration structure V2' (e.g., serration U2) is offset toward the display module 100, while the individual serration of the other of the first serration structure V1' and the second serration structure V2' (e.g., serration U1) is offset away from the display module 100. In this way, the first serration structure V1' and the second serration structure V2' can smoothly engage along the interlocking direction DK when the first elastic body Q1 and the second elastic body Q2 approach and push against each other, and misalignment is avoided by the guiding slope. Furthermore, this design reduces the number of manual steps or stages in the engagement process of the first serrated structure V1' and the second serrated structure V2' (e.g., the bending process or the pre-assembly process). Additionally, since the bending of the display module 100 results in different pressure levels on the first elastic body Q1 and the second elastic body Q2 near the end 202 and bottom 201, this beveled engagement structure can further reduce or avoid uneven stress on the first elastic body Q1 and the second elastic body Q2 during the compression process, and the beveled structure can conform to the direction of the bending compression. Therefore, the bending process of the display panel 100 can be made more natural, and the possible bending operation steps can be simplified.

[0101] In the following text, reference will be made to Figure 14 and Figure 15 This describes an exemplary application of the display device 20 according to an embodiment of the present invention in combination with an object or environment.

[0102] Continuing from above, refer to Figure 14 and Figure 15 According to an embodiment of the present invention, the display device 20 may have the same or similar structure or details as the display device 10 described above, and the following description will focus only on the differences from the display device 10 described above. As described above, according to this embodiment, the display device 20 may further include a storage base 800. The storage base 800 may include a base 500 for fixing the cable retractor 400 and the first side S1 of the display module 100, and a housing 850 connected to the base 500 and surrounding and defining the accommodating space AS.

[0103] As mentioned above, such as Figure 14 and Figure 15 As shown, the storage base 800 defines an opening OP exposing the receiving space AS. Continuing above, the display device 20 can be bent by pulling back the cable 300 using the cable retractor 400 to cover at least a portion of the opening OP (e.g., ...). Figure 14(as shown); and / or by releasing the loose cable 300 through the cable retractor 400 to unfold the display module 100 and further expose at least a portion of the opening OP (as shown). Figure 15 (As shown). Therefore, the display module 100 can be further configured as a cover based on its flexibility. Furthermore, according to this embodiment, the main body 200 and the elastic module Q, which provide flexibility, structural stability, and support, are arranged along the back surface B2 of the display module 100, and do not occupy or only partially occupy the accommodating space AS. Therefore, according to this embodiment, the accommodating space AS can also be further configured for storage purposes, allowing users to place various objects.

[0104] As mentioned above, refer to Figure 14 and Figure 15 The cable retractor 400 can retract the cable 300 to cause the display module 100 to curl towards or cover the opening OP of the storage base 800, and the cable retractor 400 can release the cable 300 to cause the display module 100 to unfold, at least partially exposing the opening OP of the storage base 800, thus opening the accommodating space AS. In this way, the display device 20, in addition to its display function, can be further integrated with the environment and objects, and through the bending and unfolding of the display module 100, it also acts as a cover for the opening OP of the accommodating space AS, which can be opened as needed to open the accommodating space AS. Therefore, according to this embodiment, the display device 20 can further reduce or avoid occupying the space and / or volume of the environment or objects, and can further expand its applicability and operational flexibility. Furthermore, as shown above, since the display device 20 further defines a storage space AS that can be used for storage by means of the display module 100 as a cover together with the storage base 800, the display device 20 according to this embodiment can further increase the storage space in the environment or objects.

[0105] In summary, according to the embodiments of the present invention, a display device with the expected flexibility, structural stability, and support can be realized, and the space occupied by the actuation mechanism during bending and unfolding can be reduced or avoided. Therefore, according to the embodiments of the present invention, a display device with improved operational flexibility and reliability can be realized, and its possible application scenarios can be further expanded, and its applicability to various objects and environments can be improved. It can even be further combined with various objects and environments to achieve more diverse functionalities.
