Description

Display device

The invention relates to a display device. Specifically, the present invention relates to a display device with a buffer mechanism.

In recent years, with the vigorous development and widespread use of electronic devices, in addition to actual functions and efficiency, the improvement of the appearance of electronic devices has gradually attracted attention. In addition, in order to enhance the aesthetics of the overall electronic device, the frame can be reduced or specific components or circuits can be hidden. For example, in order to reduce the frame or hide specific components or circuits, a flexible substrate can be used to bend the edge of the side, so that the flexible substrate beyond the boundary and the components or circuits on it can be accommodated and positioned. Behind the whole device. However, the flexible substrate that is bent and concave on the side edge may be subjected to external force collisions during assembly, transportation or use, and therefore, stress may be generated, which may cause damage to the flexible substrate and the components or circuits it carries. Damage or defect. In addition, under the impact of an external force, the flexible substrate may also move or deform unexpectedly, which may result in misalignment or pressure in the assembly of the components of the overall device. Therefore, in such a design setting, it is necessary to develop a structure or method that can reduce the impact of external force collision, and can quickly dissipate the stress and restore the original shape or original position when the stress is received.

The flexible substrate has a first part, a second part, and a bending part between the first part and the second part. Among them, the flexible substrate has a front surface and a back surface. When the back surfaces of the first part and the second part face each other, the bending part is curved and extends between the first part and the second part. The buffer mechanism includes: a supporting part with a supporting end, and a buffer material. The supporting end abuts against the back of the bending part, and one end of the buffer material relatively close to the supporting end is connected to the supporting part. Wherein, the buffer material can be compressed and stretched to allow the supporting part to move along the back of the first part and the second part.

Compare the effects of previous technologies

According to the display device provided by various embodiments of the present invention, the impact and damage of the display device caused by external force can be reduced or avoided based on the arrangement of the buffer mechanism. Therefore, the components of the display device can be protected and the configuration of the display device can be maintained while realizing the expected appearance, such as reducing the frame or hiding specific components or circuits.

Various embodiments will be described below, and those skilled in the art should be able to easily understand the spirit and principle of the present invention by referring to the description and the accompanying drawings. However, although some specific embodiments will be specifically described in the text, these embodiments are only illustrative, and are not regarded as restrictive or exhaustive in every respect. Therefore, for those with ordinary knowledge in the technical field, various changes and modifications to the present invention should be obvious and easily reachable without departing from the spirit and principle of the present invention.

1, according to an embodiment of the present invention, a display device 10 may include a flexible substrate 100 having a front surface S1 and a back surface S2. For example, the flexible substrate 100 can be made of any material such as Mylar polyester film or PET film, and the present invention is not limited thereto. In addition, the flexible substrate 100 may have a first part 110, a second part 120, and a bending part 115 between the first part 110 and the second part 120 according to the respective blocks. According to some embodiments, the front surface S1 of the first portion 110 of the flexible substrate 100 can be used as the display area 910 for displaying, but this is only an example, and the present invention is not limited thereto. For example, the first part 110 of the flexible substrate 100 can also be a part of the display device 10 for other purposes such as touch control. In addition, the bent portion 115 and the second portion 120 can be used as parts for arranging other components or purely extending from the first portion 110 without any purpose.

The above-mentioned flexible substrate 100 can be bent and folded at the side edge P1 of the display device 10 to accommodate the second part 120 and folded on the other side of the display device 10 opposite to the first part 110. For example, according to some embodiments, the front surface S1 of the second part 120 may be provided with components such as a circuit board 930 (such as COP, FPC, IC, etc.), and the second part 120 can be folded back by accommodating the second part 120. The components of this part are stored on the other side opposite to the first part 110, so that the frame feeling of the display device 10 can be reduced or the components can be hidden and protected. At this time, the back surfaces S2 of the first part 110 and the second part 120 may face each other. In addition, when the back surfaces S2 of the first portion 110 and the second portion 120 face each other, the bending portion 115 is bent and extends between the first portion 110 and the second portion 120.

In some embodiments, it is better to maintain the curvature of the bent portion (ie, the bent portion 115) when the reflexed second portion 120 is stored. However, this part is prone to be impacted by unexpected external forces to change the curvature, and even cause the deformation, displacement, misalignment, damage and other negative effects of the associated components. For example, the flexible substrate 100 may have line defects or cracks.

As mentioned above, according to this embodiment, a buffer mechanism 1000 can be further arranged in the space R surrounded by the back surface S2 of the flexible substrate 100, thereby reducing or avoiding the negative impact caused by unexpected external force collisions. . Specifically, the buffer mechanism 1000 may include a supporting part 200 having a supporting end 205 and a buffer material 300. The supporting end portion 205 can abut the back surface S2 of the bending portion 115 to support the flexible substrate 100. Further, according to some embodiments, the support end 205 may be a curved support end 205, such as an elliptical or spherical support end 205, so as to more gently and naturally abut the bending portion 115 of the flexible substrate 100. The back side S2 of the device can reduce or avoid damage to the bent portion 115. However, the foregoing is only an example, and the shape and shape of the support end 205 are not limited to the examples shown here.

In some embodiments, the supporting portion 200 may be made of materials such as rubber, fiber, PET, PMMA, or PC, and may have a Young's modulus E=0.1-5 GPa, for example. However, the above is only an example, and the material of the supporting part 200 of the present invention is not limited to this under the stress that the bending part 115 can absorb.

Based on the foregoing, the buffer material 300 in the buffer mechanism 1000 is relatively close to the supporting end 205 at one end that can be connected to the supporting part 200. For example, as shown in FIG. 1, the cushioning material 300 can be connected to the supporting portion 200 at the connection point 11, and with this arrangement, the cushioning material 300 can be compressed and stretched, thereby allowing the supporting portion 200 to extend along the first portion 110 and the first portion 110. The back S2 of the second part 120 moves. For example, the supporting portion 200 may include a main body portion 250 extending from the supporting end portion 205 along the back surface S2 of the first portion 110 and the second portion 120, and one end of the cushioning material 300 relatively close to the supporting end portion 205 can be connected to the main body of the supporting portion 200部250. With this arrangement, when an external force collides with the bending portion 115 and relatively causes the support portion 200 abutting the bending portion 115 to move as a whole, the buffer material 300 can be compressed and stretched by the moving main body portion 250, thereby allowing the support portion 200 moves along the back surface S2 of the first part 110 and the second part 120.

In one embodiment, the buffer mechanism 1000 may further include a base member 500, and compared to the support portion 200, the base member 500 does not move or relatively moves less when the bending portion 115 is impacted by an external force. On the other hand, the other end of the cushioning material 300 relatively far away from the supporting end 205 can be connected to the relatively fixed base member 500, so that the supporting part 200 can be non-fixedly connected to the base member 500 by the cushioning material 300 and can be opposite to each other. When the base member 500 moves, the cushioning material 300 is compressed or stretched. For example, as shown in FIG. 1, the buffer material 300 may be connected to the base member 500 at the connection point 12. For example, as shown in FIG. 1, the base member 500 may be a frame 510 that frames the main body 250 of the supporting portion 200, and the buffer material 300 includes a main spring 350. On the other hand, one end of the main body spring 350 relatively close to the supporting end 205 is connected to the main body 250, and the other end relatively far away from the supporting end 205 is connected to the frame 510, so that the main body spring 350 can be compressed and expanded.

According to this embodiment, the frame 510 (the base member 500) can be, for example, a rectangular hollow spring groove, and can be used to define the space where the main body 250 is inserted and the main spring 350 (buffer material 300) moves. The relatively fixed frame 510 (the base member 500) can be directly or indirectly fixedly connected to the back surface S2 of the first part 110 and the back surface S2 of the second part 120. For example, the frame 510 can be directly fixedly connected to the back surface S2 of the first part 110 and the back surface S2 of the second part 120, or can be fixedly connected to the first part indirectly through an intermediary to support the back film 920 of the flexible substrate 100 The back surface S2 of the 110 and the back surface S2 of the second part 120 are on. However, the foregoing is only an example, and the present invention can be provided with other interposing film layers between the back surface S2 of the flexible substrate 100 and the frame 510 (the base member 500) is not limited to the examples described herein.

Further referring to FIG. 2, which is a schematic view of the display device 10 from above, the display device 10 with the above-mentioned configuration can be additionally assembled with the casing 800 to provide a better protection effect. Here, for the sake of brevity, the components other than the buffer mechanism 1000 only schematically depict the flexible substrate 100 and the casing 800 and not the back film 920 and other components, so as to compare the corresponding positions with FIG. 1.

According to an embodiment of the present invention, please refer to FIG. 3A of the cross-sectional view of the buffer mechanism 1000 taken along the section line AA' of FIG. 2, or FIG. 3B of the side view of the side view of the buffer mechanism 1000, in the buffer In the mechanism 1000, the main body spring 350 can be wound around at least a part of the main body part 250 and disposed in the frame 510. Thereby, the integral support part 200 will be more stable when it moves according to the compression and extension of the main spring 350. However, this is only an example, and the two ends of the buffer material 300 are respectively connected to the support part 200 and the base member 500, etc., the buffer material 300 of the present invention, such as the main body spring 350, may not wrap the main body part 250 but only Extending along the main body 250 makes the configuration and assembly of the components in the display device 10 more flexible and flexible.

Next, referring to FIG. 4A to FIG. 4C and FIG. 5, the flow of the reaction action of the display device 10 according to an embodiment when subjected to an external force collision will be described.

In accordance with the above, referring to FIGS. 4A and 4B, and FIG. 5, when the display device 10 shown in FIGS. 1 to 3B is impacted by an external force F at the side edge P1, the external force F presses the bending of the flexible substrate 100 The folding part 115 makes it deviate from the reference line L1 of the original alignment under no pressure. At this time, the external force F will first be buffered by the supporting part 200 having the supporting end 205 to absorb part of the stress. For example, the supporting portion 200 may have a preset damping coefficient C, such as but not limited to C: 10-100 N*S/m, and may thereby absorb and relieve part of the stress. Then, the stress that is not absorbed by the buffer will press the buffer material 300 such as the main spring 350 as the support portion 200 moves in a direction opposite to the side edge P1, and is converted into the elastic force of the buffer material 300 such as the main spring 350. For example, the buffer material 300 such as the main spring 350 may have a predetermined elastic coefficient K, such as but not limited to K: 100~1000 N/m, and can thereby convert and relieve part of the stress. Finally, referring to FIGS. 4C and 5, as the support portion 200 moves along the back surface S2 of the first portion 110 and the second portion 120, the elastic force accumulated by the compression cushioning material 300, such as the main body spring 350, rebounds, so that the cushioning material 300 resembles the main body spring. 350 stretches again, and the belt is pulled through the connection point 11 fixed to the supporting part 200 to drive the supporting part 200 to move toward the side edge P1. Thereby, the supporting portion 200 can be moved back along the back surface S2 of the first portion 110 and the second portion 120, so that the supporting end portion 205 and the bending portion 115 of the flexible substrate 100 supported by it can return to On the reference line L1 that was originally aligned.

During the aforementioned process of moving to the original position under the impact of the external force F, the base member 500 such as the frame 510 can be substantially continuously aligned with the reference line L2 without moving. That is, the supporting part 200 and the buffer material 300 such as the main body spring 350 can change their positions relative to the base member 500, and the base member 500 can be relatively fixed without moving. However, the above is only an example, and as long as the supporting portion 200 and the buffer material 300 such as the main body spring 350 can change positions relative to the base member 500, in some cases, the base member 500 may also be displaced due to the collision.

With the above configuration and reaction action, according to an embodiment, the stress and pressure experienced by the flexible substrate 100 and the overall display device 10 on the reference line L1 can be reduced to 1/6 of the external force F.

Next, referring to FIG. 6, a display device 20 according to another embodiment of the present invention will be described, and the same or similar components or details as the above-mentioned display device 10 will be omitted or simply mentioned.

In addition, as shown in FIG. 6, the display device 20 is similar to the above-mentioned display device 10 and may include a flexible substrate 100 and a buffer mechanism 2000 arranged in the space R surrounded by the back surface S2 of the flexible substrate 100. Similarly, the buffer mechanism 2000 may include a supporting part 200 having a supporting end 205 and a buffer material 300. However, in this embodiment, the supporting portion 200 may include a first elastic piece 210 and a second elastic piece 220. For example, the first elastic piece 210 and the second elastic piece 220 may be made of stainless steel (SUS). The front end has a curved bend and the rear end has an elastic piece with a support body extending. Specifically, the first elastic piece 210 and the second elastic piece 220 may have curved ends 215 and 225, respectively, and the curved ends 215, 225 of the first elastic piece 210 and the second elastic piece 220 may be joined together to form the aforementioned support端部205. In addition, the supporting end portion 205 can abut the back surface S2 of the bending portion 115 to support the flexible substrate 100. However, the above is only an example, and to reduce or avoid damage to the bent portion 115, the shape and shape of the supporting end 205 formed by the joint splicing of the first elastic piece 210 and the second elastic piece 220 are not limited to those shown here.的例。 Examples.

In this embodiment, the base member 500 may also be included, and the base member 500 may be, for example, a carrier 520 sandwiched between the first elastic piece 210 and the second elastic piece 220. On the other hand, compared with the support part 200, the base member 500 does not move or relatively moves less when the bending part 115 is impacted by an external force. On the other hand, the carrier 520 (the base member 500) can be, for example, a base along which the first elastic piece 210 and the second elastic piece 220 move, and can be used to define the space where the first elastic piece 210 and the second elastic piece 220 move.

Like the display device 10 described above with reference to FIGS. 1 to 5, the buffer material 300 in the buffer mechanism 2000 of the display device 20 is relatively close to the support end 205 and can be connected to the support 200 at one end. For example, the buffer material 300 may have a first spring 310 and a second spring 320. On the other hand, one end (connection point 11) of the first spring 310 relatively close to the support end 205 is connected to the first elastic piece 210, and the other end (connection point 12) relatively far away from the support end 205 is connected to the carrier 520; and One end (connection point 11) of the second spring 320 relatively close to the support end 205 is connected to the second elastic piece 220, and the other end (connection point 12) relatively far away from the support end 205 is connected to the carrier 520. Under this arrangement, the buffer material 300 such as the first spring 310 and the second spring 320 can be compressed and stretched, thereby allowing the support part 200 such as the first elastic piece 210 and the second elastic piece 220 to extend along the first portion 110 and the second portion 120 The back S2 moves. Thereby, when the external force collides with the bending portion 115 and relatively causes the supporting portion 200 abutting the bending portion 115 to move, the buffer material 300 such as the first spring 310 and the second spring 320 can be respectively moved by the first elastic piece 210 The second elastic piece 220 and the second elastic piece 220 are driven to compress and expand, thereby allowing the supporting portion 200 such as the first elastic piece 210 and/or the second elastic piece 220 to move along the back surface S2 of the first part 110 and the second part 120.

According to this embodiment, the above-mentioned first elastic piece 210 that can move after a collision can be directly or indirectly fixedly connected to the back S2 of the first part 110, and the second elastic piece 220 that can move after a collision can be directly or indirectly fixedly connected to the back S2 of the first part 110. It is fixedly connected to the back surface S2 of the second part 120. For example, the first elastic piece 110 and the second elastic piece 120 (supporting portion 200) can be directly fixedly connected to the back surface S2 of the first part 110 and the back surface S2 of the second part 120, or can be used to support the flexible substrate through an intermediary. The back film 920 of 100 is indirectly connected to the back surface S2 of the first part 110 and the back surface S2 of the second part 120 respectively. However, the above is only an example, and the present invention can be provided on the back surface S2 of the flexible substrate 100 and other intermediary film layers between the first elastic sheet 110 and the second elastic sheet 120 (supporting portion 200) are not limited to this.的例。 Examples.

Next, referring to FIG. 7, which is a schematic view of the display device 20 from above, the display device 20 having the above configuration can be additionally assembled with the casing 800. Here, for the sake of brevity, the components other than the buffer mechanism 2000 only schematically depict the flexible substrate 100 and the casing 800 and not the backing film 920 and other components, so as to compare the corresponding positions with FIG. 6.

According to an embodiment of the present invention, please refer to FIG. 8 of the side view of the side view of the buffer mechanism 2000. In the buffer mechanism 2000, the first spring 310 can wind at least a part of the first elastic piece 210, and the second spring 320 can wind around the second spring. At least a part of the two elastic pieces 220 makes the entire first elastic piece 210 and the second elastic piece 220 more stable when they move according to the compression and expansion of the first spring 310 and the second spring 320. However, this is only an example, and the two ends of the first spring 310 or the second spring 320 are respectively connected to the first elastic piece 210 or the second elastic piece 220 and components such as the base member 500. The cushioning material 300 of the present invention is as The first spring 310 or the second spring 320 may not be wound around the first elastic piece 210 or the second elastic piece 220 but only extend along the first elastic piece 210 or the second elastic piece 220, so that the arrangement and assembly of the components in the display device 20 are more improved. Free and flexible.

Next, a display device 30 according to another embodiment of the present invention will be explained with reference to FIG. 9. In conclusion, the display device 30 is substantially the same as the display device 20 described with reference to FIG. 6 to FIG.

As shown in FIG. 9, the display device 30 also has a buffer mechanism 3000 similar to the buffer mechanism 2000 of the display device 20. Further, the base member 500 of the buffer mechanism 3000, that is, the carrier 520 facing the first elastic sheet 210 may have a first surface H1. The first surface H1 may have at least one first sliding groove G1. The first sliding grooves G1 may extend along the direction in which the first elastic piece 210 extends. In addition, with the arrangement of the first sliding groove G1, the resistance of the first elastic piece 210 when moving can be reduced, and the effect of stress relief can be improved.

According to some embodiments, the first sliding grooves G1 may be symmetrically arranged on the carrier 520, for example, an even number of first sliding grooves G1 may be symmetrically arranged on the carrier 520, so that the first elastic pieces 210 are aligned along the carrier 520. The force is more even when moving. However, under the condition that the first elastic sheet 210 can be moved along the carrier 520, the above is only an example, and the present invention is not limited thereto.

Next, referring to FIG. 10A, in one embodiment, the display device 40 also has a buffer mechanism 4000 similar to the buffer mechanism 2000 of the display device 20. On the other hand, the base member 500 of the buffer mechanism 4000, that is, the carrier 520 may have a first surface H1 facing the first elastic piece 210, and may have a second surface H2 facing the second elastic piece 220. The first surface H1 may have at least one first sliding groove G1 and the second surface H2 may have at least one second sliding groove G2. The first sliding grooves G1 and the second sliding grooves G2 can respectively extend along the extending direction of the first elastic piece 210 and the second elastic piece 220. Further, the first elastic piece 210 has at least one first protrusion 615 protruding from the first sliding grooves G1 and embedded in the first sliding grooves G1, and the second elastic piece 220 has protruding from the second sliding grooves G2 And at least one second bump 625 is embedded in the second sliding grooves G2.

Next, referring to FIG. 10B again, in another embodiment, the display device 50 also has a buffer mechanism 5000 similar to the buffer mechanism 4000 of the display device 40. The difference between the display device 50 and the display device 40 is that it does not have at least one first protrusion 615 protruding and embedded in the first sliding grooves G1 and at least one second protrusion protruding and embedded in the second sliding grooves G2. Block 625. As mentioned above, in the display device 50, at least one ball 605 is arranged in the first sliding groove G1 and/or the second sliding groove G2 instead.

As mentioned above, whether the first protrusion 615/second protrusion 625 or the ball 605 is provided, the structure helps the first elastic piece 210 and the second elastic piece 220 to be respectively aligned with the first chute of the carrier 520 G1 and the second chute G2 move. In conclusion, with the above arrangement, the resistance of the first elastic piece 210 and/or the second elastic piece 220 when moving can be reduced, and the effect of stress relief can be improved.

In addition, in some embodiments, as shown in FIGS. 10A and 10B, in order to avoid interference, the first spring 310 and/or the second spring 320 may be relative to the first sliding grooves G1 and/or the second sliding grooves G1 and/or the second sliding grooves, respectively, to avoid interference. The groove G2 is located away from the supporting end 205.

The above-mentioned embodiments shown in FIGS. 10A and 10B are merely aspects, and other embodiments according to the present invention may have other changes. For example, a first bump 615 may be provided for the first sliding groove G1, and a ball 605 may be provided for the second sliding groove G2, or vice versa. In addition, it is also possible to only provide structures such as bumps or balls for the sliding grooves on one surface, while the sliding grooves on the other surface are not equipped with related matching components. Alternatively, only one surface may be provided with a chute, while the other surface is not provided with a chute, and corresponding mechanisms are provided in the chute. In summary, the present invention is not limited to the implementation aspects detailed here.

Hereinafter, with reference to FIGS. 11A to 11C and FIG. 12, the flow of the reaction action of the display device 50 when subjected to an external force collision according to an embodiment will be described.

As mentioned above, referring to FIGS. 11A and 11B, and FIG. 12, when the display device 50 shown in FIG. The part 115 makes it deviate from the reference line L3 of the original alignment without pressure. At this time, referring to FIG. 12 together with FIGS. 11A and 11B, the external force F will press the supporting end 205 composed of the curved ends 215 and 225 of the first elastic piece 210 and the second elastic piece 220, and convert it into a curved shape. The elasticity of the ends 215 and 225. For example, the curved ends 215 and 225 may have a predetermined elastic coefficient K1, such as but not limited to K1: 100~500 N/m. Then, the stress that has not been buffered and converted will continue to press, so that the first elastic piece 210 and the second elastic piece 220 slide along the first surface H1 and the second surface H2 of the carrier 520, respectively, and follow the direction of the external force F in the opposite direction. Move on the side edge P1. For example, it slides on the carrier 520 with the assistance of the balls 605 set up in the first sliding groove G1 and the second sliding groove G2. Thereby, part of the stress can be absorbed by the sliding rail mechanism established by the first elastic piece 210 and the second elastic piece 220 and the carrier 520. For example, the slide mechanism established by the first elastic piece 210 and the second elastic piece 220 and the carrier 520 may have a preset damping coefficient C, such as but not limited to C: 10~100 N*S/m, and can thereby absorb Relieve part of the stress. Then, the stress that is not absorbed by the buffer will move along with the movement of the first elastic piece 210 and the second elastic piece 220 to press the buffer material such as the first spring 310 and the second spring 320, thereby converting into elastic force and converting to relieve part of the stress. For example, the first spring 310 and the second spring 320 may have a predetermined elastic coefficient K2, such as but not limited to K2: 100~1000 N/m.

Finally, referring to FIGS. 11C and 12, as the first elastic piece 210 and the second elastic piece 220 of the support portion 200 move in a direction opposite to the side edge P1 along the carrier 520, the first spring 310 and the second spring 320 are compressed. The accumulated elastic force rebounds, causing the first spring 310 and the second spring 320 to expand again, and the first elastic piece 210 and the second elastic piece 220 are pulled by the connecting point 11 fixed to the first elastic piece 210 and the second elastic piece 220 to move. . Thereby, the first elastic piece 210 and the second elastic piece 220 can be moved back to the side edge P1 along the first surface H1 and the second surface H2 of the carrier 520, so that the first elastic piece 210 and the second elastic piece The supporting end portion 205 formed by 220 and the bending portion 115 of the flexible substrate 100 supported by it return to the original alignment reference line L3 again.

During the aforementioned process of moving to the original position after being impacted by the external force F, the base member 500 such as the carrier 520 can be substantially continuously aligned with the reference line L4 without moving. That is, the supporting part 200 such as the first elastic piece 210 and the second elastic piece 220 and the buffer material such as the first spring 310 and the second spring 320 can change the position relative to the base member 500, and the base member 500 can be relatively unchanged. fixed. However, the above is only an example, and as long as the supporting part 200 such as the first elastic piece 210 and the second elastic piece 220 and the buffer material such as the first spring 310 and the second spring 320 can change the position relative to the base member 500, in some cases, The base member 500 may also be displaced with the collision.

With the above configuration and reaction action, according to an embodiment, the stress and pressure experienced by the flexible substrate 100 and the overall display device 50 on the reference line L3 can be reduced to 1/8 of the external force F.

Hereinafter, the flow of the reaction action of the display device 50 according to another embodiment when subjected to an external force F collision will be further described with reference to FIGS. 13A to 13D.

In summary, referring to FIGS. 13A and 13B, when the display device 50 in FIG. 10B is impacted by an external force F at the side edge P1 in the lower half, the external force F presses the bending portion of the flexible substrate 100 115, make it deviate from the reference line L3 of the original alignment under no pressure. At this time, the external force F only presses the second elastic piece 220, and is converted into elastic force based on the curved end 225 of the second elastic piece 220. Then, the stress that has not been buffered and converted will continue to press, so that the second elastic piece 220 slides along the second surface H2 of the carrier 520 and moves in the direction of the external force F opposite to the side edge P1. For example, it slides on the carrier 520 with the assistance of the ball 605 set in the second sliding groove G2. In this way, part of the stress can be absorbed by the sliding rail mechanism established by the second elastic piece 220 and the carrier 520. Then, the stress that has not been absorbed by the buffer will press the buffer material such as the second spring 320 along with the movement of the second elastic piece 220, thereby converting it into elastic force to relieve part of the stress.

Next, please refer to FIGS. 13B and 13C, because the flexible substrate 100 can be formed integrally, and the first elastic piece 210 and the second elastic piece 220 are directly or indirectly fixedly connected to the flexible substrate 100, respectively. The first part 110 and the second part 120 are on the first part 110 and the second part 120. Therefore, under the above-mentioned action, the first elastic piece 210 may also act accordingly as shown in FIG. 13C. In detail, when the second elastic piece 220 is forced to move in a direction opposite to the side edge P1, the second part 120 fixedly connected to the second elastic piece 220 then moves in a direction opposite to the side edge P1 move. Therefore, as the second portion 120 moves, the bending portion 115 moves counterclockwise and downward, so that the upper first portion 110 moves toward the side edge P1. Based on the movement of the first part 110 of the flexible substrate 100, the first elastic piece 210 fixedly connected to it also moves in the direction of the side edge P1.

Based on the above configuration and response action, the first spring 310 can be stretched due to being pulled by the first elastic piece 210, and the second spring 320 can be compressed due to being squeezed by the second elastic piece 220. In this way, the stress can be converted into the accumulated elastic force. Finally, referring to FIGS. 13C and 13D, the accumulated elastic force causes the first spring 310 to retract again and the second spring 320 to expand again, and the displaced first elastic piece 210 and the second elastic piece 220 are pulled back to the original position again. Specifically, as the first spring 310 is retracted again, the first elastic piece 210 moves in a direction opposite to the side edge P1, and as the second spring 320 is re-expanded, the second elastic piece 220 moves toward Move in the direction of the side edge P1. Therefore, the supporting end 205 composed of the first elastic piece 210 and the second elastic piece 220 and the bent portion 115 of the flexible substrate 100 supported by it can return to the original alignment reference line L3 again

During the aforementioned process of moving to the original position after being impacted by the external force F, the base member 500 such as the carrier 520 can be substantially continuously aligned with the reference line L4 without moving. However, in some cases, the base member 500 may also be displaced due to the collision. The above situation is the same as or similar to the above-mentioned embodiment, and will not be repeated here.

Next, with reference to FIGS. 14A to 14D, the flow of the reaction action of the display device 50 according to another embodiment of the present invention when subjected to an external force F collision will be described.

As mentioned above, compared with the above-mentioned FIGS. 13A to 13D, the operation difference of FIGS. 14A to 14D is that the display device 50 is impacted by the external force F on the upper half of the side edge P1. Therefore, referring to FIGS. 14A and 14B, the external force F presses the bending portion 115 of the flexible substrate 100 to deviate it from the reference line L3 of the original alignment without pressure, and causes the first elastic piece 210 to follow along The first surface H1 of the carrier 520 slides and moves in the direction of the external force F opposite to the side edge P1. Then, the stress not absorbed by the buffer will press the buffer material such as the first spring 310 as the first elastic piece 210 moves. Continuing to refer to FIGS. 14B and 14C, under the above-mentioned action, the first part 110 fixedly connected to the first elastic piece 210 moves in a direction opposite to the side edge P1. Therefore, as the first portion 110 moves, the bending portion 115 moves clockwise upward, and the second portion 120 below moves toward the side edge P1. Furthermore, based on the movement of the second part 120 of the flexible substrate 100, the second elastic piece 220 fixedly connected to it also moves in the direction of the side edge P1.

Based on the above configuration and reaction action, the first spring 310 can be compressed due to being squeezed by the first elastic piece 210, and the second spring 320 can be stretched due to being pulled by the second elastic piece 220. Finally, referring to FIGS. 14C and 14D, the accumulated elastic force causes the first spring 310 to expand again and the second spring 320 to retract again, and the displaced first elastic piece 210 and the second elastic piece 220 are pulled back to the original position again. Specifically, as the first spring 310 is re-expanded, the first elastic piece 210 is moved toward the side edge P1, and as the second spring 320 is retracted again, the second elastic piece 220 is moved in the opposite direction. Move in the direction of the side edge P1. Therefore, the supporting end 205 composed of the first elastic piece 210 and the second elastic piece 220 and the bent portion 115 of the flexible substrate 100 supported by it can return to the original alignment reference line L3 again

During the aforementioned process of moving to the original position after being impacted by the external force F, the base member 500 such as the carrier 520 can be substantially continuously aligned with the reference line L4 without moving. However, in some cases, the base member 500 may also be displaced due to the collision. The above situation is the same as or similar to the above-mentioned embodiment, and will not be repeated here.
