[0028] Figure 1is a structural schematic diagram of a first display module provided by an embodiment of the present application, Figure 2 is a structural schematic diagram of a second display module provided by an embodiment of the present application, Figure 3 is Figure 1 is a first cross-sectional schematic view along section line A-A' in FIG. 1, referring to Figures 1-3 , an embodiment of the present application provides a display module 10, which includes a bendable region 10B and a non-bendable region 10A; the display module 10 further includes a display panel 100 and a support structure 200, the support structure 200 being located at a non-light-emitting side of the display panel 100; the support structure 200 includes a support body 210, a plurality of slots 220 penetrating at least partially through the support body 210 along a first direction X, and a first pressure adjusting structure 230 located in the slots 220, at least part of the slots 220 and at least part of the first pressure adjusting structure 230 being located in the bendable region 10B; the first pressure adjusting structure 230 includes a first state and a second state, the pressure borne by the first pressure adjusting structure 230 in the first state being greater than the pressure borne by the first pressure adjusting structure 230 in the second state, and the Young's modulus of the first pressure adjusting structure 230 in the first state being greater than the Young's modulus of the first pressure adjusting structure 230 in the second state.
[0029] Specifically, referring to Figure 1 and Figure 2 , the display module 10 includes a display panel 100 and a support structure 200, the display panel 100 being configured to realize the display function of the display module 10, and the support structure 200 being configured to provide a support force, thereby ensuring the structural stability of the display module 10 as a whole. Moreover, the support structure 200 is located at the non-light-emitting side of the display panel 100, that is, the support structure 200 is arranged in a manner that does not block and affect the display of the display panel 100, thereby ensuring the display effect of the display module 10 as a whole. Optionally, the display panel 100 includes a plurality of light-emitting elements (not specifically shown in the figure), a driving circuit configured to drive the light-emitting elements to display and emit light, signal traces, and the like, and the embodiments of the present application do not make detailed descriptions thereof. Optionally, the display module 10 further includes a back plate assembly located away from the display panel 100 of the support structure 200, a cover plate located away from the support structure 200 of the display panel 100, and the like, and the embodiments of the present application do not make detailed descriptions thereof.
[0030] Further, the display module 10 includes a non-bendable region 10A and a bendable region 10B, wherein the non-bendable region 10A can be understood as a display region that does not deform, and the bendable region 10B is a display region that can deform and bend. In combination with Figure 1 and Figure 2 , the display module 10 can be bent at the bendable region 10B as shown in Figure 2 , thereby realizing the foldable design of the display module 10 and the like. It should be noted that,Figure 2 It can be understood as Figure 1 The three-dimensional view is used to show the shape of the display panel 100 and the support structure 200 when the display module 10 is bent in the bending area 10B.
[0031] The support structure 200 includes a support body 210, which provides overall support for the display module 10. The support structure 200 also includes multiple slots 220, which extend through at least a portion of the support body 210 along the thickness direction of the display module 10. At least a portion of the slots 220 are located in the bendable region 10B, ensuring that stress concentration is avoided in the bendable region 10B when the display module 10 is bent. Figure 2 When the display module 10 is bent, the stress at the bending area 10B is dispersed by the slot 220; or it can be understood that the slot 220 provided in the bending area 10B of the support structure 200 can prevent the support structures 200 from squeezing each other when the display module 10 is bent, thereby ensuring the stability of the structure.
[0032] Furthermore, the support structure 200 also includes a first pressure adjustment structure 230, which is disposed within the slot 220. The first pressure adjustment structure 230 can have different states, and under different states, the pressure it bears is different. This ensures that the bending area 10B of the support structure 200 has different compressive strength under different stress conditions, thereby guaranteeing the overall structural stability of the display module 10.
[0033] Specifically, the pressure that the first pressure regulating structure 230 can withstand in the first state is greater than the pressure that it can withstand in the second state. Furthermore, the Young's modulus of the first pressure regulating structure 230 in the first state is greater than that in the second state. This can be understood as follows: in the first state, the first pressure regulating structure 230 has relatively high hardness and can withstand relatively high pressure; while in the second state, its hardness is relatively low and it can withstand relatively low pressure. Because the Young's modulus of the first pressure regulating structure 230 differs in different states, and the pressure it can withstand also differs, this ensures that the pressure-bearing capacity of the display module 10 can be adjusted accordingly under different stress conditions, thereby ensuring the overall structural stability and bendability of the display module 10.
[0034] For example, if the display module 10 is a touch display module, the first state can be understood as the situation where a finger or stylus slides or clicks in the bending area 10B, and the second state can be understood as the situation where the finger or stylus does not slide or click in the bending area 10B. In the first state, when a finger or stylus clicks or slides in the bending area 10B, the display module 10 is equivalent to being impacted by an external force. In this case, the Young's modulus of the first pressure adjustment structure 230 is relatively large, that is, the hardness of the first pressure adjustment structure 230 is relatively large, and it can withstand greater pressure, thereby ensuring that the display module 10 can withstand greater pressure, thus avoiding deformation such as dents in the bending area 10B of the display module 10, that is, ensuring the overall structural stability of the display module 10. In the second state, when the finger or stylus does not click or slide in the bending area 10B, the display module 10 is equivalent to being without external impact. In this case, the Young's modulus of the first pressure adjustment structure 230 can be relatively small, that is, the hardness of the first pressure adjustment structure 230 is relatively small. In other words, the support structure 200 is relatively soft in the bending area 10B, which makes it easier for the display module 10 to bend in the bending area 10B, thus facilitating the bending design of the display module 10.
[0035] In summary, the display module provided by the embodiments of the present invention includes a display panel and a support structure. The display panel is used to realize the display function of the display module. The support structure includes a support body, a slot, and a first pressure adjustment structure. The first pressure adjustment structure can include a first state and a second state. In the first state, the pressure borne by the first pressure adjustment structure is greater than the pressure borne by the first pressure adjustment structure in the second state. Moreover, the Young's modulus of the first pressure adjustment structure in the first state is greater than the Young's modulus of the first pressure adjustment structure in the second state. This reflects that the first pressure adjustment structure can withstand different pressures in different states. Therefore, the display module can ensure the overall structural stability and bendability under different conditions.
[0036] Figure 4 yes Figure 3 The first enlarged schematic diagram of region B in the middle, see reference. Figures 1-4 As shown, the first pressure regulating structure 230 includes a non-Newtonian fluid 231 and loss particles 232 doped inside the non-Newtonian fluid 231; the first pressure regulating structure 230 has a greater loss capacity in the first state than the first pressure regulating structure 230 has in the second state.
[0037] Specifically, the first pressure adjusting structure 230 includes a non-Newtonian fluid 231 and loss particles 232, wherein the non-Newtonian fluid 231 refers to a fluid that does not satisfy the Newtonian viscosity experimental law, that is, a fluid whose shear stress and shear strain rate are not in a linear relationship. Further, in the first pressure adjusting structure 230, the loss particles 232 are doped inside the non-Newtonian fluid 231. Because of the presence of the loss particles 232, when the first pressure adjusting structure 230 is subjected to pressure, the loss ability is improved, that is, the ability to absorb pressure is improved, and the hardness is increased, thereby achieving a good supporting effect. Similarly, when the first pressure adjusting structure 230 is not subjected to pressure, the loss ability remains unchanged, and the hardness remains unchanged. The adjustment ability of the non-Newtonian fluid 231 and the loss particles 232 to pressure can be understood as the pressure absorption ability. Therefore, under the action of the non-Newtonian fluid 231 and the loss particles 232, the first pressure adjusting structure 230 can exhibit different Young's moduli under different pressures, that is, the Young's modulus corresponding to the pressure that the first pressure adjusting structure 230 can withstand is adjusted when the pressure is different. In this way, the ability of the display module 10 to withstand pressure can be correspondingly adjusted under different stress conditions, thereby ensuring the structural stability and bendability of the display module 10 as a whole.
[0038] Figure 5 is Figure 3 A second enlarged schematic view of the region B in FIG. 10 is shown in FIG. 11. As shown in FIG. 11, the first pressure adjusting structure 230 includes a first adjusting part 230a and a second adjusting part 230b, and the first adjusting part 230a is located on the side of the second adjusting part 230b close to the display panel 10. The doping proportion of the loss particles 232 in the first adjusting part 230a is greater than the doping proportion of the loss particles 232 in the second adjusting part 230b. Figures 1-3 Figure 5 As shown in FIG. 11, the first pressure adjusting structure 230 includes a first adjusting part 230a and a second adjusting part 230b, and the doping proportion of the loss particles 232 in the first adjusting part 230a is greater than the doping proportion of the loss particles 232 in the second adjusting part 230b.
[0039] As shown in FIG. 11, the first pressure adjusting structure 230 includes a first adjusting part 230a and a second adjusting part 230b, and the doping proportion of the loss particles 232 in the first adjusting part 230a is greater than the doping proportion of the loss particles 232 in the second adjusting part 230b.
[0040] Specifically, because of the position of the external pressure force, the different regions of the first pressure adjusting structure 230 have different pressure sizes. Therefore, by differentiating the pressure absorption ability of the first pressure adjusting structure 230, the ability of the first pressure adjusting structure 230 to withstand pressure can be better adjusted correspondingly under different stress conditions, thereby ensuring the structural stability and bendability of the display module 10 as a whole.
[0041] Specifically, referring to Figure 5 As shown in , the first adjusting part 230a is located at the side of the second adjusting part 230b close to the display panel 10, and the doping proportion of the loss particles 232 in the first adjusting part 230a is greater than that in the second adjusting part 230b. Further, taking the touch pressure as an example, it is applied in the display panel, so in the first pressure adjusting structure 230, the area close to the display panel 100 will bear a larger pressure, so the doping proportion of the loss particles 232 in the first adjusting part 230a is greater than that in the second adjusting part 230b, to ensure that the first pressure adjusting structure 230 has adaptability in the ability to bear pressure under different stress conditions. For example, for the case that the display module 10 is subjected to external force, it can be understood that the display module 10 is a touch display module, and the finger or touch pen slides and clicks on the display panel 100, and the pressure borne by the first adjusting part 230a is greater than that borne by the second adjusting part 230b, so the doping proportion of the loss particles 232 in the first adjusting part 230a is adjusted, to further ensure the structural stability and bendability of the display module 10 as a whole.
[0042] Figure 6 is Figure 3 a first enlarged schematic view of the area C in , is Figure 7 a first enlarged schematic view of the area D in , referring to Figure 1 , Figures 1-3 , Figure 6 and Figure 7 As shown in , the support structure 200 includes a first pressure adjusting structure 2301 and a first pressure adjusting structure 2302, and the first pressure adjusting structure 2301 is located at the side of the first pressure adjusting structure 2302 away from the non-bending area 10A; the doping proportion of the loss particles 232 in the first pressure adjusting structure 2301 is greater than that in the first pressure adjusting structure 2302.
[0043] , referring to Figure 6 and Figure 7As shown, the support structure 200 includes a first pressure adjusting structure 2301 and a first pressure adjusting structure 2302, wherein the first pressure adjusting structure 2301 is located on the side of the first pressure adjusting structure 2302 away from the non-bending area 10A. And the doping proportion of the loss particles 232 in the first pressure adjusting structure 2301 and the doping proportion of the loss particles 232 in the first pressure adjusting structure 2302 are designed differently, so as to further ensure the stability of the overall structure of the display module 10. Wherein, the first pressure adjusting structure 2301 and the first pressure adjusting structure 2302 can be understood as the first pressure adjusting structure 230 filled in the slot 220 with different distances from the non-bending area 10A in the support structure 200.
[0044] Specifically, compared with the non-bending area 10A, the number of slots 220 in the area away from the non-bending area 10B is larger, and the support body 210 is more missing. Under the same bearing pressure, the first pressure adjusting structure 230 needs to bear a larger pressure. Therefore, the first pressure adjusting structure 230 away from the non-bending area 10B has a larger pressure bearing capacity. Therefore, in order to ensure that the support structure 200 has balanced pressure bearing, the pressure bearing capacity of the first pressure adjusting structure 230 in the slot 220 away from the non-bending area 10A can be greater than that of the first pressure adjusting structure 230 in the slot 220 close to the non-bending area 10A.
[0045] Specifically, referring to Figure 6 and Figure 7 As shown, the first pressure adjusting structure 2301 is located on the side of the first pressure adjusting structure 2302 away from the non-bending area 10A, and the doping proportion of the loss particles 232 in the first pressure adjusting structure 2301 is greater than that in the first pressure adjusting structure 2302. The pressure bearing capacity of the first pressure adjusting structure 2301 can be greater than that of the first pressure adjusting structure 2302, that is, according to the difference of the setting position of the slot 220, the doping proportion of the loss particles 232 of the first pressure adjusting structure 220 filled in the slot 220 is adaptively adjusted, further ensuring the structural stability and bendability of the overall display module 10.
[0046] Figure 8 is Figure 1 second cross-sectional view along the section line A-A', referring to Figure 1 and Figure 8As shown, the support structure 200 further comprises a second pressure adjusting structure 240 located in the slot 220; the second pressure adjusting structure 240 is located at the side of the first pressure adjusting structure 230 close to the display panel 10, and the Young's modulus of the second pressure adjusting structure 240 is greater than the Young's modulus of the first pressure adjusting structure 230.
[0047] Specifically, referring to Figure 8 As shown, the slot 220 provided in the support structure 200 can be filled with the first pressure adjusting structure 230 and the second pressure adjusting structure 240, and the second pressure adjusting structure 240 is located at the side of the first pressure adjusting structure 230 close to the display panel 10. That is, the first pressure adjusting structure 230 and the second pressure adjusting structure 240 filled in the slot 220 have a difference in position in the first direction X.
[0048] Further, the Young's modulus of the second pressure adjusting structure 240 is greater than the Young's modulus of the first pressure adjusting structure 230, which can be understood as the hardness of the second pressure adjusting structure 240 is greater than the hardness of the first pressure adjusting structure 230, so the load capacity of the second pressure adjusting structure 240 to pressure is greater than the load capacity of the first pressure adjusting structure 230 to pressure. And the second pressure adjusting structure 240 is arranged at the side close to the display panel 100, which can on the one hand improve the load capacity of the support structure 200 to pressure as a whole, and on the other hand can also ensure the flatness of the support structure 200 at the slot 220, so as to ensure that the support structure 200 can provide a good flatness setting condition for the display panel 100, thereby ensuring good display effect.
[0049] Figure 9 is Figure 8 The first enlarged schematic view of the region E, referring to Figure 1 and Figure 9 As shown, the support structure 200 comprises a first slot 221 and a second slot 222, the first slot 221 is located at the side of the second slot 222 away from the non-bending area 10A; along the first direction X, the thickness of the first pressure adjusting structure 230 in the first slot 221 is d11, the thickness of the second pressure adjusting structure 240 is d21, the thickness of the first pressure adjusting structure 230 in the second slot 222 is d12, and the thickness of the second pressure adjusting structure 240 is d22; wherein d11 / d21 < d12 / d22.
[0050] Further, by adjusting the thickness difference of the first pressure adjusting structure 230 and the second pressure adjusting structure 240 in the groove 220, the pressure bearing capacity in the corresponding groove 220 can be differentiated. Specifically, the support structure 200 includes a first groove 221 and a second groove 222, where the first groove 221 is located on the side of the second groove 222 away from the non-bending area 10A. Compared to the area close to the non-bending area 10A, the area away from the non-bending area 10B has more grooves 220 and more missing support bodies 210. Under the same bearing pressure, the first pressure adjusting structure 230 needs to bear more pressure, so the first pressure adjusting structure 230 in the area away from the non-bending area 10B has a larger pressure bearing capacity. Therefore, in order to ensure that the support structure 200 has balanced pressure bearing, the pressure bearing capacity of the first pressure adjusting structure 230 and the second pressure adjusting structure 240 in the first groove 221 away from the non-bending area 10A can be greater than the pressure bearing capacity of the first pressure adjusting structure 230 and the second pressure adjusting structure 240 in the second groove 222 close to the non-bending area 10A.
[0051] Further, the Young's modulus of the second pressure adjusting structure 240 is greater than the Young's modulus of the first pressure adjusting structure 230, so increasing the thickness ratio of the second pressure adjusting structure 240 in the groove 220 can enhance the pressure bearing capacity of this area. In combination with Figure 9 As shown, the thickness of the first pressure adjusting structure 230 in the first groove 221 is d11, the thickness of the second pressure adjusting structure 240 is d21, the thickness of the first pressure adjusting structure 230 in the second groove 222 is d12, and the thickness of the second pressure adjusting structure 240 is d22; wherein d11 / d21 < d12 / d22, which can be understood as the ratio of the first pressure adjusting structure 230 and the second pressure adjusting structure 240 in the first groove 221 is less than the ratio of the first pressure adjusting structure 230 and the second pressure adjusting structure 240 in the second groove 222, that is, the thickness ratio of the first pressure adjusting structure 230 in the first groove 221 is small, and the thickness ratio of the second pressure adjusting structure 240 is large, while the thickness ratio of the first pressure adjusting structure 230 in the second groove 222 is large, and the thickness ratio of the second pressure adjusting structure 240 is small. Further, the pressure bearing capacity of the groove 220 in different positions is adaptively adjusted, so as to ensure the pressure bearing balance of different areas of the support structure, and further ensure the structural stability of the display module 10 as a whole.
[0052] Continuing to refer to Figure 1 and Figure 8As shown, along the first direction X, the thickness of the first pressure adjusting structure 230 is d1, the thickness of the second pressure adjusting structure 240 is d2, and the depth of the slot 220 is d3; wherein 80%≤d1 / d3≤95%; 5%≤d2 / d3≤20%.
[0053] Further, 80%≤d1 / d3≤95% can be understood as the ratio between the thickness of the first pressure adjusting structure 230 and the depth of the slot 220 being between 80%-95%, at this time the first pressure adjusting structure 230 is more filled in the slot, but it does not completely fill the slot. Since the first pressure adjusting structure 230 has a large Young's modulus under a large pressure, its "strong when strong" characteristic can ensure that the support structure has a relatively wide pressure bearing range, ensuring that the support structure can have wide applicability under different degrees of pressure. And even if the first pressure adjusting structure 230 is provided with loss particles, the overall Young's modulus is still smaller than that of the support body 210, that is, relative to the support body 210, the first pressure adjusting structure 230 still has good softness characteristics, ensuring that the bending area 10B has good bending properties.
[0054] 5%≤d2 / d3≤20% can be understood as the ratio between the thickness of the second pressure adjusting structure 240 and the depth of the slot 220 being between 5%-20%, at this time the second pressure adjusting structure 230 is partially filled in the slot, but the filling ratio is smaller than that of the first pressure adjusting structure 240. Due to the large Young's modulus of the second pressure adjusting structure 240, the setting of the second pressure adjusting structure 240 can improve the pressure bearing energy and flatness performance of the support structure 200. When the second pressure adjusting structure 240 has a small filling ratio, it ensures that it will not greatly interfere with the bendability of the bending area, ensuring good bendability of the display module.
[0055] Figure 10 is Figure 3 A third enlarged schematic view of the area B, referring to Figures 1-3 、 Figure 10 As shown, in the same slot 220, there is a gap between the first pressure adjusting structure 230 located in the slot 220 and the side wall 220a of the slot 220.
[0056] Specifically, referring to Figure 10 As shown, there is a gap d between the first pressure adjusting structure 230 and the side wall 220a of the slot 220 in the slot 220, that is, the first pressure adjusting structure 230 and the side wall 220a of the slot 220 are not in contact. By ensuring that the side wall 220a of the slot 220 and the first pressure adjusting structure 230 have a gap d, the display module 10 can be easily bent in the bending area 10B, thereby ensuring the overall structural stability of the display module 10.
[0057] Optionally, in the preparation process of the support structure 200, after the groove 220 is set, the first pressure adjusting structure 230 is filled before the surface of the side wall 220a of the groove 220 is set with a dispensing or other filling film layer, and then the first pressure adjusting structure 230 is prepared. After the first pressure adjusting structure 230 is prepared, the film layer filled at the side wall 220a is removed, so as to realize the non-contact design between the first pressure adjusting structure 230 and the side wall 220a of the groove 220. For the material of the film layer filled at the side wall 220a during preparation, the embodiments of the present application do not make specific limitation, which is used to ensure that there is a gap d between the first pressure adjusting structure 230 and the side wall 220a of the groove 220.
[0058] Figure 11 is Figure 1 is a third cross-sectional view along the section line A-A' in FIG. 10, and Figure 1 and Figure 11 It is shown that the first pressure adjusting structure 230 includes the light shielding structure 250.
[0059] Specifically, as shown in Figure 11 , the first pressure adjusting structure 230 includes the light shielding structure 250, that is, the first pressure adjusting structure 230 itself has the light shielding property and can shield light, or it is understood that the first pressure adjusting structure 230 itself is a light-absorbing material and can absorb and block the light transmitted to the first pressure adjusting structure 230.
[0060] Further, the first pressure adjusting structure 230 set in the groove 220 includes the light shielding structure 250, that is, it can be understood that the non-Newtonian fluid 231 in the first pressure adjusting structure 230 is the light shielding structure, that is, the first pressure adjusting structure 230 itself can block and shield the light transmitted to it, thereby ensuring that the display effect of the display panel 100 will not be disturbed, so as to ensure the display effect of the display module 10 as a whole. And in the case that the first pressure adjusting structure 230 itself can shield light, the additional light shielding structure at the groove 220 can also be reduced, thereby reducing the overall process preparation cost of the display module 10.
[0061] Figure 12 is Figure 1 is a fourth cross-sectional view along the section line A-A' in FIG. 11, and Figure 1 and Figure 12 It is shown that the first pressure adjusting structure 230 includes the light-transmitting structure 260; the display module 10 further includes a light shielding layer 270 located on the side of the support structure 200 away from the display panel 100, and the light shielding layer 270 covers the plurality of grooves 220 along the first direction X.
[0062] For details, please refer to Figure 12 As shown, the first pressure adjustment structure 230 includes a light-transmitting structure 260, meaning that when light is transmitted to the first pressure adjustment structure 230, the light continues to transmit. To prevent light from transmitting at the slot 220 and affecting the overall display effect of the display module 10, a light-shielding layer 270 is added to the side of the support structure 200 away from the display panel 100. The light-shielding layer 270 has light-shielding properties and can block light, or it can be understood that the light-shielding layer 270 itself is a light-absorbing material that can absorb and block the light transmitted to the light-shielding layer 270.
[0063] refer to Figure 12 As shown, along the thickness direction of the display module 10, the light-shielding layer 270 covers multiple slots 220, which can prevent the slots 220 set in the support structure 200 from affecting the overall display effect of the display module 10.
[0064] Figure 13 yes Figure 1 A schematic diagram of the fifth type of section along section line A-A', see reference. Figure 1 and Figure 13 As shown, the slot 220 includes a first opening 223 on the side closer to the display panel 100 and a second opening 224 on the side farther from the display panel 100; the opening area of the first opening 223 is smaller than the opening area of the second opening 224.
[0065] Among them, reference Figure 13 As shown, the slot 220 includes a first opening 223 and a second opening 224, wherein the first opening 223 is closer to the display panel 100 than the second opening 224. Furthermore, the shape of the slot 220 can be adjusted by adjusting the opening areas of the first opening 223 and the second opening 224.
[0066] Specifically, the slot 220 in the support structure 200 needs to have good pressure bearing capacity near the display panel 100 to ensure the overall structural stability of the display module 10. Therefore, the opening area of the first opening 223 is adjusted to be smaller than the opening area of the second opening 224, or the slot 220 is set as an inverted trapezoid. This ensures that the area of the support body 210 near the display panel 100 is larger, thus ensuring good pressure bearing capacity of the support structure 200.
[0067] Furthermore, when the non-bending areas 10A on both sides of the display module are... Figure 2When the bending mode shown is bent, the bottom end of the slot 220, that is, the end away from the display panel 100, is subjected to a greater extrusion stress, at which time the slot 220 has a larger opening area at this location, and a larger amount of the first pressure adjusting structure 230, which is relatively soft compared to the support body 210, is filled therein, which can ensure that the bendability of the display module is good.
[0068] With reference to the foregoing Figures 1-13 As shown, along the first direction X, the thickness of the first pressure adjusting structure 230 is less than or equal to the depth of the slot 220, and the first pressure adjusting structure 230 is located within the slot 220.
[0069] Further, along the first direction X, that is, along the thickness direction of the display module 10, the thickness of the first pressure adjusting structure 230 is adjusted to be less than or equal to the depth of the slot 220, that is, to avoid the first pressure adjusting structure 230 from protruding from the slot 220, which can also be understood as that at the support structure 200, there is no location where the first pressure adjusting structure 230 protrudes, that is, to ensure the flatness of the overall structure of the display module 10.
