Abstract
Description
Technical Field
[0001] The present invention relates to the field of display technology, and more particularly, to a supporting structure, a display module, and a display device. Background Art
[0002] In panel display technology, organic light-emitting diode (OLED) display technology differs from traditional liquid crystal display (LCD) technology in its self-luminous properties. OLEDs utilize a very thin organic material coating and a glass substrate. Their numerous advantages, including fast response time, wide viewing angle, rich colors, low power consumption, and high and low temperature resistance, have made them a key development technology in the industry. OLED display panels, after receiving external signals from the drive circuit, control the operating state of the thin-film transistors to apply a preset ideal potential to the reflective anode, creating a potential difference between the reflective anode and the semi-transparent cathode. Electrons and holes are injected from the cathode and anode, respectively, into the luminescent material layer, thereby stimulating the material to produce luminescence.
[0003] In related technologies, a support structure is provided between the display panel and the package cover. The support structure includes multiple support columns for supporting the package cover. When the support structure is subjected to a large external impact, it will collapse, causing irreversible damage to the display panel and affecting the display effect. Summary of the Invention
[0004] In view of this, the present invention provides a supporting structure, a display module and a display device, which can improve the supporting effect of the supporting structure.
[0005] In a first aspect, the present invention provides a support structure comprising a substrate and a plurality of dopants disposed inside the substrate, wherein the elastic modulus of the dopants is greater than the elastic modulus of the substrate.
[0006] In a second aspect, the present invention provides a display module, comprising the support structure provided in the first aspect of the present invention.
[0007] In a third aspect, the present invention provides a display device comprising the display module provided in the second aspect of the present invention.
[0008] Compared with the prior art, the support structure, display module, and display device provided by the present invention achieve at least the following beneficial effects:
[0009] The support structure provided by the present invention can improve the overall buffering effect of the support structure by arranging multiple doping parts in the matrix, and the elastic modulus of the doping parts is greater than the elastic modulus of the matrix. When the support structure is impacted by an external force, the doping body included in the matrix can absorb most of the impact force, and slowly release it after the external force disappears, returning to its original state, thereby avoiding the collapse of the matrix and causing irreversible pressure damage to other components. At the same time, since the elastic modulus of the matrix is smaller than that of the doping body, it can also ensure that the support structure has a certain strength to meet the support requirements. Therefore, doping the matrix of the support structure with a doping body with a higher elastic modulus can ensure that the support structure has a certain strength while improving the buffering capacity, thereby improving the support effect of the support structure.
[0010] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.
[0025] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
[0026] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0027] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0028] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0029] In the related art, refer to Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a display module in related art. A support structure is provided between the display panel 02 and the package cover 01. The support structure includes multiple support columns 03, which are used to support the package cover 01. When subjected to a large external force, the support structure will collapse, causing irreversible damage to the display panel 01 and affecting the display effect.
[0030] In order to solve the above technical problems, the embodiment of the present invention provides a support structure, referring to Figure 2 As shown, Figure 2 This is a schematic diagram of a support structure provided by an embodiment of the present invention. The support structure 100 includes a substrate 10 and a plurality of doping bodies 20 disposed inside the substrate 10 . The elastic modulus of the doping bodies 20 is greater than that of the substrate 10 .
[0031] It is understandable that the support structure 100 in the prior art only includes a base 10. In order to ensure sufficient support strength, the elastic modulus of the base 10 is relatively small. Therefore, when subjected to external force impact, the support structure 100 is prone to collapse. In the embodiment provided by the present invention, a plurality of dopants 20 are filled inside the base 10, and the elastic modulus of the dopants 20 is greater than the elastic modulus of the base 10. Arranging a plurality of dopants 20 in the base 10 can improve the overall elastic modulus of the support structure 100. In this way, when subjected to external force impact, the dopants 20 doped in the base 10 can absorb most of the impact force and slowly release it after the external force disappears, thereby avoiding the collapse of the support structure 100 due to the excessively small elastic modulus of the base 10.
[0032] It should be noted that the schematic diagram provided in the embodiment of the present invention only illustrates the structure of the matrix 10 and the dopant 20, and does not represent the actual distribution, size and shape of the matrix 10 and the dopant 20. In the embodiment provided in the present invention, the dopant 20 can be distributed throughout the matrix 10, or can be located only in part. In the embodiment provided in the present invention, the shape of the dopant 20 can be, for example, a sphere. However, the shape of the dopant 20 provided in the embodiment of the present invention is not limited to a sphere, and can also be a cube, etc. The schematic diagram provided in the embodiment of the present invention also does not represent the doping amount of the dopant 20. In the embodiment provided in the present invention, the doping amount and doping density of the dopant 20 are not limited and can be set according to the application scenario.
[0033] Furthermore, a dopant 20 is provided in the substrate 10 of the support structure 100. After coating the substrate 10, the substrate 10 is subjected to ion bombardment to form a cavity, or air is mixed into the substrate 10 material to form a cavity. The dopant 20 is then filled into the cavity. Since the support structure 100 has a certain height, the dopant 20 can be provided in layers. Specifically, a substrate 10 of a certain thickness can be coated, and then the substrate 10 is subjected to ion bombardment to form a cavity, and then the cavity is filled with the dopant 20. Then, a substrate 10 of a certain thickness is continuously coated, and the substrate 10 is subjected to ion bombardment to form a cavity, and the cavity is continuously filled with the dopant. The above steps are repeated until the height of the support structure 100 meets the preset height, thereby realizing the layered filling of the dopant 20. It should be noted that the schematic diagram provided by the present invention is only a schematic diagram of the substrate, and is not used to represent the specific shape of the substrate 10. As shown in the accompanying drawings, the cross-section of the substrate 10 can be trapezoidal or rectangular. Conversely, the shape of the substrate 10 can be truncated cone, cylindrical, or cubic, etc. This is not specifically limited in the present invention. Therefore, in the above-described process of preparing the support structure 100, the area of each layer of the substrate 10 can be the same or different. The number of cavities formed by each ion bombardment of the substrate 10 can be the same or different, and this is not specifically limited in the present invention.
[0034] In an optional embodiment provided by the present invention, referring to Figure 3 As shown, Figure 3 This is a schematic diagram of another supporting structure provided by an embodiment of the present invention. The dopant 20 is a sponge structure 21, and a hole 200 is provided in the sponge structure 21.
[0035] It can be understood that in the embodiment provided by the present invention, the dopant 20 is a sponge structure 21. The sponge structure 21 is a porous structure. Specifically, holes 200 are provided in the sponge structure 21. The holes 200 of the sponge structure 21 have a buffering effect. When the support structure 21 is impacted by an external force, the sponge structure 21 can absorb most of the impact force, thereby avoiding the collapse of the support structure 100 due to the small elastic modulus of the matrix 10, and then causing pressure damage to other components. After the external force disappears, the sponge structure 21 can also slowly release the force, and the sponge structure 21 returns to its original state, so that the support structure 100 has a larger change space in shape, that is, the support structure 100 has a larger deformation capacity, which improves the support effect of the support structure 100.
[0036] Furthermore, the number of holes 200 included in the sponge structure 21 can be multiple, and the thickness of the sponge structure 21 between the multiple holes 200 can be designed according to the volume of the dopant 20 and the volume of the holes 200. It is understandable that, under the premise of ensuring the support effect of the support structure 100, the more holes 200 there are, the better the cushioning effect of the sponge structure 21, which is more conducive to improving the support effect of the support structure 100.
[0037] In an optional embodiment provided by the present invention, the dopant 20 is a nano-organic matter 22 .
[0038] It is understood that in the embodiment provided by the present invention, the dopant 20 is a nano-organic substance 22. The elastic modulus of the nano-organic substance 22 is greater than that of the substrate 10. When the support structure 21 is impacted by an external force, the nano-organic substance 22 can absorb most of the impact force, thereby preventing the support structure 100 from collapsing due to the low elastic modulus of the substrate 10.
[0039] Optionally, refer to Figure 4 As shown, Figure 4Schematic diagram of another support structure provided by an embodiment of the present invention. The nano-organic material 22 may include a hole 200. The hole 200 may include one or more holes. When the nano-organic material 22 includes one hole 200, the hole 200 may be set at the geometric center of the hole 200. When the nano-organic material 22 includes more than one hole 200, the holes 200 may be uniformly arranged inside the nano-organic material 22. It is understood that the elastic modulus of the nano-organic material 22 is greater than that of the substrate 10. The provision of the hole 200 in the nano-organic material 22 can enhance the deformation ability of the nano-organic material 22, thereby further improving the elastic modulus of the support structure 100 as a whole and improving the support effect of the support structure 100.
[0040] In an optional embodiment provided by the present invention, in the same support structure 100 , the volume of the dopant 20 accounts for 30%-45% of the total volume of the base 10 .
[0041] It is understood that within the same support structure 100, the volume proportion of the dopant 20 needs to be controlled within a certain proportion. For example, in the embodiments provided by the present invention, the volume of the dopant 20 accounts for 30%-45% of the total volume of the substrate 10 in which it is located. Specifically, within the same support structure 100, if the volume of the dopant 20 accounts for less than 30% of the total volume of the substrate 10, the volume proportion of the dopant 20 is too small. The overall elastic modulus of the same support structure 100 is too small, the strength is too high, and it cannot serve as a buffer. Within the same support structure 100, if the volume of the dopant 20 accounts for more than 45% of the total volume of the substrate 10, the volume proportion of the dopant 20 is too large. The overall elastic modulus of the same support structure 100 is too large, the strength is too low, and it cannot serve as a support. Therefore, in the embodiments provided by the present invention, within the same support structure 100, the volume of the dopant 20 accounts for 30%-45% of the total volume of the substrate 10, which can meet both the buffering requirements of the support structure 100 and the support requirements of the support structure. For example, the volume of the dopant 20 may account for 30%, 35%, 40%, 45%, etc. of the total volume of the base 10 .
[0042] In an optional embodiment provided by the present invention, referring to Figure 5 As shown, Figure 5 Schematic diagram of the dimensional relationship of a support structure provided by an embodiment of the present invention: The gap d2 between adjacent doping bodies 20 is greater than the radial length d1 of the doping body 20.
[0043] It is understood that the dopants 20 are distributed within the substrate 10. Although the embodiments provided herein do not specifically limit the number and distribution of the dopants 20, the gap d2 between adjacent dopants 20 must be greater than the radial length d1 of the dopants 20. This design ensures that the dopants 20 are distributed within the same support structure 100 with a certain spacing, preventing them from being too densely packed, and preventing the overall or local elastic modulus of the support structure 100 from being too large, thereby affecting the support effectiveness of the support structure 100.
[0044] Specifically, the gap d2 between adjacent doped bodies 20 refers to the minimum distance between adjacent doped bodies 20. The radial length d1 of the doped body 20 refers to the maximum distance within the doped body 20. The gap d2 between adjacent doped bodies 20 is greater than the radial length d1 of the doped body 20, which ensures a certain support strength along the direction connecting the adjacent doped bodies 20, thereby preventing the support structure 100 from collapsing due to insufficient support strength.
[0045] Furthermore, when the sizes of the doped bodies 20 in the same support structure 100 are different, the gap d2 between adjacent doped bodies 20 is greater than the larger value of the radial length d1 of the adjacent doped bodies 20. This ensures that the gap d2 between any adjacent doped bodies 20 is greater than the radial length d1 of the adjacent doped bodies 20, thereby ensuring the support strength of the support structure 100.
[0046] In an optional embodiment provided by the present invention, referring to Figure 6 As shown, Figure 6 A schematic diagram of another support structure provided by an embodiment of the present invention. The support structure 100 includes a top surface 101 and a bottom surface 102, which are parallel to each other. Along a direction x pointing from the top surface to the bottom surface, the distribution density of the dopants 20 gradually decreases. The density of the dopants 20 included on the top surface 101 of the support structure 100 is greater than the density of the dopants 20 included on the bottom surface 102 of the support structure 100.
[0047] It will be appreciated that support structure 100 includes opposing top surface 101 and bottom surface 102, which are parallel to each other. In one embodiment, the area of top surface 101 is smaller than that of bottom surface 102. In another embodiment, the area of top surface 101 is equal to that of bottom surface 102. A direction x, which is drawn from top surface 101 to bottom surface 102, is generally the vertically downward direction of support structure 100. Support structure 100 is disposed between other structures or devices to provide support.
[0048] Furthermore, in the embodiment provided by the present invention, in the same support structure 100, the distribution density of the dopant 20 gradually decreases along the direction from the top surface 101 to the bottom surface 102. In other words, along the direction from the top surface 101 to the bottom surface 102, the number of dopant 20 included in the same volume of the substrate 10 gradually decreases. From the above analysis, it can be seen that since the elastic modulus of the dopant 20 is greater than the elastic modulus of the substrate 10, the more dopant 20 there are in the same volume of the substrate 10, the greater the overall elastic modulus of the substrate 10 will be, and the better the buffering effect. However, the support structure 100 also needs to meet certain hardness requirements to ensure the support effect. Therefore, along the direction from the top surface 101 to the bottom surface 102, the distribution density of the dopant 20 gradually decreases. In this way, in the direction from the top surface 101 to the bottom surface 102, the overall elastic modulus of the substrate 10 gradually decreases, but the strength gradually increases. Because the top surface 101 of the support structure 100 is designed to absorb external impact forces, the dopant 20 in the substrate 10 near the top surface 101 has a high density, a high elastic modulus, and a good cushioning effect, enabling rapid absorption of external impact forces. The dopant 20 in the substrate 10 near the bottom surface 102 has a low density, high strength, and a good supporting effect, ensuring support for the support structure 100 when subjected to external impact forces.
[0049] Furthermore, in the same support structure 100, the distribution density of the dopant 20 gradually decreases along the direction from the top surface 101 to the bottom surface 102 by gradually depositing the substrate 10 and doping the dopant 20. Specifically, a substrate 10 of a certain thickness is formed along the direction from the bottom surface 102 to the top surface 101, and the dopant 20 is added to the substrate 10, with the ratio of the volume of the dopant 20 to the total volume of the substrate 10 being a first ratio. Then, a substrate 10 of a certain thickness is further formed on the substrate 10, and the dopant 20 is added to the substrate 10, with the ratio of the volume of the dopant 20 to the total volume of the substrate 10 being a second ratio. The second ratio is greater than the first ratio. The above steps are repeated, and the ratio of the dopant 20 added each time to the total volume of the portion of the substrate 10 gradually increases until the preset height of the support structure 100 is met. This achieves a gradually decreasing distribution density of the dopant 20 along the direction from the top surface 101 to the bottom surface 102.
[0050] In an optional embodiment provided by the present invention, referring to Figure 7 As shown, Figure 7 A surfactant 30 is provided between the contact interface between the dopant 20 and the substrate 10 .
[0051] It is understood that a surfactant 30 is provided between the contact interface of the dopant 20 and the substrate 10. The surfactant 30 can fuse the contact interface of the dopant 20 and the substrate 10 with each other, thereby improving the stability of the connection between the dopant 20 and the substrate 10, and thus improving the integrity of the support structure 100. In the embodiments provided by the present invention, the type of surfactant 30 is not specifically limited, as long as it can achieve the fusion of the contact interface of the dopant 20 and the substrate 10. Moreover, as long as it can achieve the above-mentioned functions, it falls within the scope of protection of the present invention.
[0052] Based on the same inventive concept, the present invention also provides a display module, referring to Figure 8 As shown, Figure 8 A schematic structural diagram of a display module provided by an embodiment of the present invention is shown in FIG. The display module 200 includes the support structure 100 in any of the above embodiments.
[0053] The display module provided in the embodiments of the present invention can be any electronic module with a display function, such as a touch screen display, a mobile phone, or a tablet. The display module provided in the embodiments of the present invention has the beneficial effects of the support structure provided in the embodiments of the present invention. For details, please refer to the detailed description of the support structure in the above embodiments, and will not be repeated in this embodiment.
[0054] In an optional embodiment provided by the present invention, continue to refer to Figure 8 As shown, the display module 200 further includes a display panel 02 and a packaging cover 01, wherein the display panel 02 is an organic electroluminescent display panel;
[0055] The support structure 100 is disposed between the display panel 02 and the package cover 01 . The top surface 101 of the support structure 100 is located on the side of the bottom surface 102 of the support structure 100 close to the package cover 01 . The bottom surface 102 of the support structure 100 is connected to the display panel 02 .
[0056] It can be understood that the support structure 100 is arranged between the display panel 02 and the packaging cover plate 01 to isolate and support the packaging cover plate 01. The top surface 101 of the support structure 100 is located on the side of the bottom surface 102 of the support structure 100 close to the packaging cover plate 01. The top surface 101 of the support structure 100 can be connected to the packaging cover plate 01, or it can only be in contact with the packaging cover plate 02. The bottom surface 102 of the support structure 100 is connected to the display panel 02. When the support structure 100 is subjected to a force from the direction of the packaging cover plate 01, it can improve the buffering effect of the impact force while ensuring the supporting effect. Avoid the support structure 100 from collapsing under force and damaging the display panel 02.
[0057] In an optional embodiment provided by the present invention, Figure 9 and Figure 10As shown, Figure 9 A schematic structural diagram of another display module provided by an embodiment of the present invention; Figure 10 Schematic diagram of the film structure of a display module provided by an embodiment of the present invention. The display panel 02 includes an array layer 021 and a light-emitting layer 022 located on the side of the array layer facing the package cover 01. The light-emitting layer includes a pixel definition layer 0221.
[0058] The bottom surface 102 of the support structure 100 is connected to the pixel definition layer 0221 .
[0059] It is understood that in the embodiment provided by the present invention, the display panel 02 is an organic electroluminescent display panel, and the display panel 02 includes an array layer 021 and a light-emitting layer 022 located on the side of the array layer 021 facing the package cover plate 01. The light-emitting layer 022 includes a pixel definition layer (not shown in the figure). The bottom surface 102 of the support structure 100 is connected to the pixel definition layer. When the support structure 100 is subjected to a force from the direction of the package cover plate 01, it can improve the buffering effect of the impact force while ensuring the support effect. Avoid the support structure 100 from collapsing under force and damaging the pixel definition layer 0221.
[0060] In an optional embodiment provided by the present invention, the base 10 of the support structure 100 and the pixel definition layer 0221 are made of the same material.
[0061] It is understood that the materials of the base 10 of the support structure 100 and the pixel definition layer 0221 can be the same or different. In the embodiment provided by the present invention, the material of the base 10 of the support structure 100 is the same as that of the pixel definition layer 0221. During the preparation process of the display panel 02, the support structure 100 can be prepared at the same time as the pixel definition layer 0221. This facilitates the preparation of the support structure 100 and simplifies the process flow.
[0062] Specifically, the support structure 100 can be formed by exposing and developing on the pixel definition layer 0221. When multiple support structures 100 are provided between the display panel 02 and the package cover plate 01, gaps between adjacent support structures 100 can be formed by masking.
[0063] In an optional embodiment provided by the present invention, the base 10 of the support structure 100 and the pixel definition layer 0221 are both made of polyimide.
[0064] It is understood that in the embodiments provided herein, the substrate 10 of the support structure 100 and the pixel definition layer 0221 are made of the same material: polyimide. Polyimide (PI) refers to a class of polymers containing an imide ring (-CO-NR-CO-) in its backbone. It is one of the organic polymer materials with the best overall performance and is a commonly used material in display panel technology. Therefore, using polyimide for both the substrate 10 of the support structure 100 and the pixel definition layer 0221 facilitates production and manufacturing.
[0065] Based on the same inventive concept, the present invention also provides a display device, referring to Figure 11 As shown, Figure 11 This is a top view of a display device provided by an embodiment of the present invention. The display device includes the display module in any of the above embodiments.
[0066] The display device provided in the embodiments of the present invention can be any electronic device with a display function, such as a touch screen display, a mobile phone, a tablet computer, a laptop computer, an e-reader, or a television. The display device provided in the embodiments of the present invention has the beneficial effects of the display module provided in the embodiments of the present invention. For details, please refer to the detailed description of the display module in the above embodiments, and will not be repeated in this embodiment.
[0067] It is understandable that Figure 11 The rounded rectangular structure is used as an example to illustrate one shape of the display device. In some other embodiments of the present invention, the display device may also be rectangular, circular, elliptical or any other feasible shape, which is not specifically limited in the present invention.
[0068] In summary, the support structure, display module, and display device provided by the present invention achieve at least the following beneficial effects:
[0069] The support structure provided by the present invention can improve the overall buffering effect of the support structure by arranging multiple doping parts in the matrix, and the elastic modulus of the doping parts is greater than the elastic modulus of the matrix. When the support structure is impacted by an external force, the doping body included in the matrix can absorb most of the impact force, and slowly release it after the external force disappears, returning to its original state, thereby avoiding the collapse of the matrix and causing irreversible pressure damage to other components. At the same time, since the elastic modulus of the matrix is smaller than that of the doping body, it can also ensure that the support structure has a certain strength to meet the support requirements. Therefore, doping the matrix of the support structure with a doping body with a higher elastic modulus can ensure that the support structure has a certain strength while improving the buffering capacity, thereby improving the support effect of the support structure.
