Technical Field

[0001] The present application relates to the technical field of electronic devices, and particularly to a display device. Background Art

[0002] Currently, flexible display screens are widely used. A support plate with a punched area and a non-punched area needs to be provided under the flexible screen to support the flexible screen. The punched area is correspondingly arranged with the folding area of the flexible screen, and the hardness of the punched area is relatively low, so that the folding area can be deformed. Creases will appear at the junction of the punched area and the non-punched area of the flexible screen, affecting the display effect of the flexible screen. Summary of the Invention

[0003] The present application provides a display device for solving the problem of creases appearing at the junction of the punched area and the non-punched area of the flexible screen.

[0004] An embodiment of the present application provides a display device, which includes:

[0005] A display module;

[0006] A support member located on one side of the display module;

[0007] A first elastic member located between the display module and the support member;

[0008] Wherein, the support member is provided with a first through hole, the first through hole penetrates the support member along the thickness direction of the display device, and one side of the first elastic member connected to the support member has a first inclined surface, and the first inclined surface is connected to the edge of the first through hole.

[0009] By providing a first elastic member between the support member and the display module and providing a first inclined surface connected to the edge of the first through hole on the first elastic member, a transition area can be generated at the edge of the first through hole.

[0050] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0051] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0052] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. The singular forms “a”, “the” and “said” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0053] It should be understood that the term “and / or” used herein is only a description of the associated relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character “ / ” herein generally represents an “or” relationship between the associated objects before and after.

[0054] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the drawings, and should not be construed as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0055] As Figure 1 and Figure 2 shown, the embodiments of the present application provide a display device, including a display module 1, a support member 2, and a first elastic member 3. The support member 2 is located on one side of the display module 1, and the first elastic member 3 is located between the display module 1 and the support member 2. Among them, the support member 2 is provided with a first through hole 21, and the first through hole 21 penetrates the support member 2 along the thickness direction of the display device. One side of the first elastic member 3 connected to the support member 2 has a first inclined surface 31, and the first inclined surface 31 is connected to the edge of the first through hole 21.

[0056] The display module 1 includes a folding area 11 and a non-folding area 12. The area of the support member 2 provided with the first through hole 21 corresponds to the folding area 11 in the display module 1, and the part of the support member 2 corresponding to the non-folding area 12 is not provided with the first through hole 21. Along the thickness direction of the display device, the elastic member overlaps with the folding area 11 of the display module 1 and also overlaps with the junction of the folding area 11 and the non-folding area 12. The first inclined surface 31 in the elastic member is located at the junction of the folding area 11 and the non-folding area 12.

[0057] The area of the support member 2 corresponding to the folding area 11 of the display module 1 is provided with the first through hole 21, which reduces the bending stress of the support member 2 when the display module 1 is bent, facilitating the folding of the display device. Since the position of the support member 2 corresponding to the non-folding area 12 of the display module 1 is not provided with the first through hole 21, an indentation will be generated at the overlapping position of the folding area 11 and the non-folding area 12 in the display module 1. One side of the first elastic member 3 connected to the support member 2 is provided with the first inclined surface 31. After the display module 1 is connected to the support member 2, the first elastic member 3 reduces the possibility of direct contact between the edge of the first through hole 21 in the support member 2 and the junction position of the folding area 11 and the non-folding area 12 in the display module 1. The first inclined surface 31 in the first elastic member 3 provides a transition area for the connection between the junction position of the folding area 11 and the non-folding area 12 in the display module 1 and the support member 2. After the display module 1 is connected to the support member 2 by means of molding, etc., it is beneficial to reduce the possibility of generating indentations in the display module 1.

[0058] As Figure 3 and Figure 4As shown, in a possible embodiment, the first elastic member 3 is disposed around the first through hole 21, and along the thickness direction of the display device, the first elastic member 3 overlaps with the first through hole 21.

[0059] The first through holes 21 are spaced apart from each other on the support member 2. Structures such as mounting grooves communicating with the first through holes 21 can be provided along the circumferential direction of the first through holes 21 for mounting the first elastic member 3. The first elastic member 3 is fixed in the mounting groove so that the upper surface of the first elastic member 3 is flush with the surface of the support member 2. Along the thickness direction of the display device, the first elastic member 3 overlaps with the first through hole 21, and the area of the orthographic projection of the first elastic member 3 is larger than the area of the orthographic projection of the first through hole 21, so that the first elastic member 3 is disposed around the first through hole 21.

[0060] The first elastic member 3 is disposed around the first through hole 21, reducing the possibility of imprints being generated due to contact between the edge of the first through hole 21 and the display module 1. Fixing the first elastic member 3 to the support member 2 through structures such as mounting grooves can improve the stability of the first elastic member 3 and reduce the possibility of the first elastic member 3 moving relative to the support member 2.

[0061] As Figure 1 and Figure 5 shown, in a possible embodiment, the first elastic member 3 includes a plurality of second through holes 32. The second through holes 32 are located at the positions where the first elastic member 3 overlaps with the first through hole 21, and the area of the first through hole 21 is larger than the area of the second through hole 32.

[0062] The outer edge of the first elastic member 3 is fixed to the support member 2, and the inner edge can cover a part of the first through hole 21 along the circumferential direction of the first through hole 21.

[0063] Providing the second through holes 32 in the first elastic member 3 can reduce the bending stress of the elastic member. Since the first elastic member 3 is made of an elastic material and the support member 2 is made of a rigid material, the area of the second through hole 32 can be smaller than the area of the first through hole 21, and the first elastic member 3 can also be folded along with the display module 1. Figure 6 For the structure where the first elastic member 3 is not provided in the related art, bending holes 211' are provided in the punching area 21' of the support plate 2' so that the bending area of the support plate 2' can be bent along with the folding part 11' of the flexible screen 1'. If the area of the bending hole 211' is small, the bending stress of the punching area 21' will increase. If the area of the bending hole 211' is large, after the flexible screen 1' is attached to the support plate 2' by rolling or vacuum pressure, the flexible screen 1' will sink into the bending hole 211', resulting in imprints on the surface of the flexible screen 1'. The first elastic member 3 in the embodiment of the present application can cover a part of the first through hole 21, enabling the first elastic member 3 to support the display module 1 and reducing the possibility of imprints being generated on the surface of the display module 1.

[0064] AsFigure 1 As shown, in a possible embodiment, along the width direction of the display device, the width of the second through hole is 1 / 3 to 1 / 2 of the width of the first through hole.

[0065] Providing a second through hole in the first elastic member can reduce the bending stress of the first elastic member. If the width of the second through hole is less than 1 / 3 of the width of the first through hole, the bending stress of the first elastic member following the support member is relatively large. If the width of the second through hole is greater than 1 / 2 of the width of the first through hole, the supporting effect of the first elastic member on the display module is reduced, increasing the possibility of imprints on the surface of the display module.

[0066] As Figures 1 to 6 shown, in a possible embodiment, along the direction close to the bending axis 5 of the display device, the areas of multiple second through holes 32 gradually increase.

[0067] The bending axis 5 is located at the central position of the folding area 11 in the display module 1. The display device will fold or unfold along the bending axis 5. When the display module 1 folds, along the direction close to the bending axis 5, the deformation amplitudes of the display module 1, the support member 2, and the first elastic member 3 gradually increase.

[0068] The areas of the second through holes 32 gradually increase along the direction close to the bending axis 5, which can reduce the bending stress at the position close to the bending axis 5, facilitating the bending of the display device, and at the same time can reduce the pressure of the first elastic member 3 on the display module 1. Along the direction away from the bending axis 5, the areas of the second through holes 32 gradually decrease, increasing the support of the first elastic member 3 for the display module 1, which is beneficial to reducing the imprints on the surface of the display module 1.

[0069] As Figure 7 shown, in a possible embodiment, the cross-section of the second through hole 32 along the length direction of the display device is wavy.

[0070] In the first elastic member 3, the second through hole 32 extends along the direction of the bending axis 5. When the display device folds, the second through hole 32 will deform along the direction perpendicular to the bending axis 5.

[0071] When the display device folds, a force will be generated in the area of the first elastic member 3 where the second through hole 32 is provided and this force will be transmitted to the display module 1. Providing a wavy second through hole 32 in the first elastic member 3 can disperse the force transmitted from the area of the first elastic member 3 where the second through hole 32 is provided to the display module 1, making the force on the display module 1 more uniform and reducing the possibility of deformation of the display module 1.

[0072] As Figure 8 shown, in a possible embodiment, the cross-section of the second through hole 32 along the length direction of the display device is arc-shaped, and the second through hole 32 bends towards the direction close to the bending axis 5 of the display device.

[0073] Since the display device is folded along the folding axis 5, the arc-shaped second through hole 32 is bent in the direction close to the folding axis 5, making the first elastic member 3 more adaptable to the bending direction of the display device, reducing the acting force on the display module 1, and being beneficial to reducing the possibility of wire threading creases on the surface of the display module 1.

[0074] As Figure 9 shown, in a possible embodiment, the support member 2 includes a first support portion 22 and a second support portion 23. The first through hole 21 is located in the first support portion 22. Along the thickness direction of the display device, the first inclined surface 31 overlaps with the junction of the first support portion 22 and the second support portion 23.

[0075] The first support portion 22 and the second support portion 23 of the support member 2 are integrally formed. The first support portion 22 is connected to the folding area 11 of the display module 1. The first through hole 21 is provided in the area where the first support portion 22 is located, enabling the first area 311 to be bent along with the folding area 11. The second support portion 23 is connected to the non-folding area 12, and no through hole is provided on the second support portion 23, enabling the second support portion 23 to support the non-folding area 12 and reducing the possibility of deformation of the non-folding area 12. Along the direction from the first support portion 22 to the second support portion 23, the first inclined surface 31 inclines away from the display module 1. The height of the first support portion 22 is less than the height of the second support portion 23. The junction position of the first support portion 22 and the second support portion 23 also has an inclined surface, which is correspondingly arranged with the first inclined surface 31, so that the side facing the display module 1 is a plane after the first elastic member 3 is fixed to the support member 2.

[0076] Since the first through hole 21 is provided in the first support portion 22, after the display module 1 is fixed to the support member 2 by means of molding or the like, an imprint will appear in the area corresponding to the junction position of the display module 1 and the first support portion 22 and the second support portion 23. A first elastic member 3 is provided between the support member 2 and the display module 1, and the first inclined surface 31 is provided in the area where the first elastic member 3 is connected to the junction position of the first support portion 22 and the second support portion 23, which can reduce the possibility of the display module 1 generating an imprint.

[0077] As Figure 9 shown, in a possible embodiment, the first inclined surface 31 includes a first area 311. The first area 311 is located at the overlapping position of the first elastic member 3 and the second support portion 23. Along the direction from the first support portion 22 to the second support portion 23, the length of the first area 311 is 5 mm to 15 mm.

[0078] In the thickness direction of the display device, one side of the position where the first elastic member 3 overlaps with the first region 311 is connected to the non-folded region 12 of the display module 1, and the other side is connected to the second support portion 23. The region of the second support portion 23 connected to the first region 311 also has an inclined surface, and the slope of the inclined surface is the same as that of the first region 311.

[0079] The first region 311 in the first inclined surface 31 overlaps with the second support portion 23. The length of the first region 311 in the direction from the second support portion 23 to the first whole portion can be 5 mm, 10 mm, 15 mm, etc., preferably 10 mm. If the length of the first region 311 is less than 5 mm, the transition region between the first support portion 22 and the second support portion 23 is small, resulting in possible imprints on the display module 1. If the length of the first region 311 is greater than 15 mm, the length of the inclined region in the second support portion 23 is large, reducing the support effect of the second support portion 23 on the non-folded region 12 of the display module 1.

[0080] As Figure 9 shown, in a possible embodiment, in the length direction of the display device, the inclination angle of the first region 311 is 5° to 15°.

[0081] The inclined surface in the second support portion 23 has the same inclination angle as the first region 311, enabling the elastic member to be fixed to the second support portion 23. The inclination angle of the first region 311 can be 5°, 10°, 15°, etc., preferably 10°. If the inclination angle of the first region 311 is less than 5°, the thickness of the first elastic member 3 between the second support portion 23 and the display module 1 is small, reducing the buffering effect of the first elastic member 3 on the display module 1 and causing imprints to easily appear on the surface of the display module 1. If the inclination angle of the first region 311 is greater than 15°, the thickness of the first elastic member 3 between the second support portion 23 and the non-folded region 12 of the display module 1 is large, reducing the support effect of the second support portion 23 on the non-folded region 12.

[0082] As Figure 9 shown, in a possible embodiment, the first inclined surface 31 includes a second region 312, and the second region 312 is located at the position where the first elastic member 3 overlaps with the first support portion 22. In the direction from the second support portion 23 to the first support portion 22, the second region 312 is inclined in the direction away from the display module 1.

[0083] The second region 312 is located on the side of the first region 311 close to the bending axis 5 of the display device and is connected to the first region 311. The second region 312 is connected to the first support portion 22. Therefore, the portion of the first support portion 22 connected to the second region 312 also has an inclined surface, and the slope of the inclined surface is the same as that of the second region 312, enabling the first elastic member 3 to be fixed to the first support portion 22.

[0084] The first inclined surface 31 includes a second region 312. At the corresponding position of the first support portion 22, there is an inclined surface that inclines in a direction away from the display module 1, increasing the thickness of the first elastic member 3 between the first support portion 22 and the folding region 11 in the display module 1. When the display device is bent, the buffering effect between the first support portion 22 and the display module 1 is improved. The first region 311 and the second region 312 are connected, making the transition between the first support portion 22 and the second support portion 23 of the support member 2 smoother, which is beneficial to reducing the possibility of the display module 1 generating indentations.

[0085] In a possible embodiment, the first inclined surface 31 in the first elastic member 3 may only include the first region 311, or may include the first region 311 and the second region 312, so that the first support portion 22 and the second support portion 23 can be smoothly connected, and then the possibility of the display module 1 generating indentations can be reduced.

[0086] As Figure 9 shown, in a possible embodiment, along the direction from the second support portion 23 to the first support portion 22, the width of the second region 312 is 1 mm to 2 mm.

[0087] A plurality of first through holes 21 are provided on the first support portion 22. As Figure 9 In the side view of the support member 2, the first support portion 22 may include a plurality of support ribs and the first through holes 21 arranged alternately. The upper surface of the support rib is connected to the second region 312, the width of the second region 312 is 1 mm to 2 mm, or the number of support ribs corresponding to the second region 312 is two to four.

[0088] The width of the second region 312 may be 1 mm, 1.5 mm, 2 mm, etc., preferably 1 mm, making the transition at the junction of the first support portion 22 and the second support portion 23 smoother, reducing the possibility of the display module 1 generating indentations, and at the same time, it can also increase the thickness of the first elastic member 3 between the first support portion 22 and the display module 1, reducing the impact on the display module 1 when the display device is folded.

[0089] As Figure 9 shown, in a possible embodiment, along the length direction of the display device, the inclination angle of the second region 312 is less than or equal to 30°.

[0090] The second region 312 is connected to the first region 311, and the inclination angle of the second region 312 is greater than the inclination angle of the first region 311, but less than or equal to 30°.

[0091] If the inclination angle of the second region 312 is greater than 30°, the thickness of the first elastic member 3 between the first support portion 22 and the display module 1 is relatively large, and the supportability of the first support portion 22 for the display module 1 is relatively poor, resulting in possible imprints on the display module 1 at the junction of the first support portion 22 and the second support portion 23.

[0092] As Figure 9 shown, in a possible embodiment, the second region 312 includes a third region 312a and a fourth region 312b. Along the direction from the second support portion 23 to the first support portion 22, the fourth region 312b is located on the side of the third region 312a away from the second support portion 23. Along the length direction of the display device, the inclination angle of the fourth region 312b is greater than that of the third region 312a, and the difference in the inclination angles between the third region 312a and the fourth region 312b is 2° to 5°.

[0093] In the first support portion 22, different support ribs correspond to the third region 312a and the fourth region 312b respectively. Along the direction from the second support portion 23 to the first support portion 22, the inclination angles of the upper surfaces of different support ribs gradually increase, and the difference in the inclination angles of the upper surfaces between adjacent support ribs is 2° to 5°.

[0094] On the surface where the first elastic member 3 is connected to the support member 2, the side of the second region 312 close to the bending axis 5 is a plane, and the inclination angles of the third region 312a and the fourth region 312b in the second region 312 gradually increase. Along the direction close to the bending axis 5, the thickness of the first elastic member 3 gradually increases. When the display device is folded, along the direction close to the bending axis 5, the deformation amplitude of the display module 1 is larger. Increasing the thickness of the first elastic member 3 is beneficial to improving the elasticity between the display module 1 and the support member 2 and reducing the possibility of the first support portion 22 causing creases on the surface of the display module 1.

[0095] As Figure 9 shown, in a possible embodiment, a second elastic member 4 is provided on the side of the support member 2 away from the display module 1.

[0096] When the display device is applied to an electronic device, the side of the support member 2 away from the display module 1 is connected to the housing of the electronic device, and the second elastic member 4 is located between the support member 2 and the housing of the electronic device. Along the thickness direction of the display device, the second elastic member 4 may overlap with the first support portion 22, or overlap with both the first support portion 22 and the second support portion 23.

[0097] The second elastic member 4 increases the elasticity between the support member 2 and the housing, plays a buffering role between the housing and the support member 2 during the folding or unfolding process of the display device with the electronic device, reduces the acting force of the housing of the display device on the display module 1, and is beneficial to reducing the possibility of the display module 1 generating creases.

[0098] As Figure 9 shown, in a possible embodiment, a second inclined surface 41 is provided on a side of the second elastic member 4 connected to the support member 2. Along the direction close to the bending axis 5 of the display device, the second inclined surface 41 inclines towards the support member 2, and the inclination angle of the second inclined surface 41 is greater than that of the first inclined surface 31.

[0099] Along the thickness direction of the display device, the second elastic member 4 may overlap with the first support portion 22 and the second support portion 23. The second inclined surface 41 is provided at the junction position of the first support portion 22 and the second support portion 23, and inclined surfaces are also provided on the first support portion 22 and the second support portion 23, so that the first support portion 22 and the second support portion 23 are attached to the second inclined surface 41.

[0100] When the display device is connected to the housing of the electronic device, the second inclined surface 41 is provided on the second elastic member 4. When the display device is fixed to the electronic device, the possibility of deformation at the junction position of the first support portion 22 and the second support portion 23 due to the different structures of the first support portion 22 and the second support portion 23 is reduced, and further the possibility of the display module 1 generating imprints is reduced. The inclination angle of the second inclined surface 41 is greater than that of the first inclined surface 31, so that the thickness of the second elastic member 4 is greater than that of the first elastic member 3, which is beneficial to improving the elasticity between the support member 2 and the housing of the electronic device.

[0101] As Figure 9 and Figure 10 shown, in a possible embodiment, the second elastic member 4 includes a third through hole 42, the third through hole 42 communicates with the first through hole 21, and the area of the third through hole 42 is smaller than that of the first through hole 21.

[0102] The third through hole 42 is provided at the overlapping position of the second elastic member 4 and the first support portion 22. Along the thickness direction of the display device, the first through hole 21, the second through hole 32, and the third through hole 42 communicate with each other, and the area of the third through hole 42 may be smaller than that of the first through hole 21 and larger than that of the second through hole 32.

[0103] A third through hole 42 is provided in the second elastic member 4. When the display device is folded, the bending stress on the second elastic member 4 is reduced, and the possibility of the display device generating creases during folding is reduced. The side of the support member 2 away from the display module 1 is connected to the housing of the electronic device. If the possibility of the structure in the housing being embedded in the third through hole 42 is small during the process of fixing the support member 2 to the housing, the area of the third through hole 42 can be increased to reduce the bending stress of the second elastic member 4. If there is a risk that the structure in the housing is embedded in the third through hole 42 during the process of fixing the support member 2 to the housing, the area of the third through hole 42 can be reduced, and the second elastic member 4 can support the housing.

[0104] In a possible embodiment, the thickness of the first elastic member 3 and the second elastic member 4 is 10 μm to 50 μm.

[0105] The thickness of the first elastic member 3 and the second elastic member 4 can be 10 μm, 30 μm, 50 μm, etc. If the thickness of the first elastic member 3 and the second elastic member 4 is relatively large, the supportability of the support member 2 for the display module 1 will be reduced. If the thickness of the first elastic member 3 and the second elastic member 4 is relatively small, the elasticity between the support member 2, the display module 1 and the housing of the electronic device will be small, and the possibility of the display module 1 generating creases during the bending of the display device is increased.

[0106] In a possible embodiment, both the first elastic member 3 and the second elastic member 4 are black.

[0107] The display module 1 includes a light-emitting side and a backlight side. Both the first elastic member 3 and the second elastic member 4 are located on the backlight side of the display module 1. Both the first elastic member 3 and the second elastic member 4 are black, reducing the light transmittance of the first elastic member 3 and the second elastic member 4, which is beneficial to improving the display effect of the display module 1.

[0108] In a possible embodiment, the material of the first elastic member 3 is any one of polyurethane, silica gel, polyolefin, and rubber.

[0109] Materials such as polyurethane, silica gel, polyolefin, and rubber have elasticity and toughness, enabling the first elastic member 3 to support the display module 1. When the display device is folded, the first elastic member 3 can bend with the support member 2 and can adapt to the different shape changes of different positions in the display module 1 after folding, reducing the possibility of the support member 2 causing creases on the display module 1.

[0110] In a possible embodiment, the modulus of the first elastic member 3 is 200 MPa to 2000 MPa.

[0111] If the modulus of the first elastic member 3 is greater than 2000 MPa, the stiffness of the first elastic member 3 is relatively large, and a relatively large stress is required to deform the first elastic member 3, thereby reducing the buffering effect of the first elastic member 3 on the display module 1 and the support member 2. If the modulus of the first elastic member 3 is less than 200 MPa, the stiffness of the first elastic member 3 is relatively small, thereby reducing the support for the display module 1.

[0112] In a possible embodiment, the elongation rate of the first elastic member 3 is greater than 200%.

[0113] The first elastic member 3 needs to be folded along with the display device. After folding, the first elastic member 3 will be deformed along with the support member 2. If the elongation rate of the first elastic member 3 is small, the possibility of the first elastic member 3 breaking when the display device is folded will increase.

[0114] The material and properties of the second elastic member 4 may be the same as those of the first elastic member 3.

[0115] The first elastic member 3 and the second elastic member 4 can be fixed to the support member 2 by processes such as dip coating, spraying, coating film technology, and attachment. The second through hole and the third through hole 42 can be made by laser cutting or wire cutting.

[0116] As Figure 10 shown, in a possible embodiment, the display module 1 includes a connection component 13, a display component 14, and a cover plate 15. Along the direction away from the support member 2, the connection component 13, the display component 14, and the cover plate 15 are arranged in sequence. The connection component 13 is used to connect the display component 14 to the support member 2, and the cover plate 15 is connected to the display component 14 to reduce the influence of the external environment on the display component 14.

[0117] The embodiment of the present application provides a display device, including a display module 1, a support member 2, and a first elastic member 3. The first elastic member 3 is located between the display module 1 and the support member 2. Among them, the support member 2 includes a first through hole 21, and along the thickness direction of the display device, the first through hole 21 penetrates through the support member 2. The first elastic member 3 includes a first inclined surface 31. The first inclined surface 31 is located on the side where the first elastic member 3 is connected to the support member 2 and is connected to the edge of the first through hole 21. Since the first through hole 21 is provided in the support member 2, an indentation is generated at the edge position of the first through hole 21 after the display module 1 is connected to the support member 2. A first elastic member 3 is provided between the support member 2 and the display module 1, and a first inclined surface 31 is provided on the first elastic member 3 to form a transition region at the edge of the first through hole 21, which can reduce the possibility of the indentation being generated.

[0118] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
