[0051] FIG. 1 is a structural diagram of a display device according to some embodiments. As shown in FIG. 1, the display device 2000 includes a display module 100.

[0052] Exemplarily, the display device 2000 further includes a frame, a display driving IC (Integrated Circuit), other electronic accessories, etc.

[0053] As shown in FIG. 2, some embodiments of the disclosure provide a display module 100, which can be applied to the display device 2000 described above, of course, the display module 100 can also be applied to other display devices, the disclosure does not limit this.

[0054] In some embodiments, as shown in FIG. 2, the display module 100 includes a display panel 1 and a support 2`.

[0055] For example, the display panel 1 can be an OLED (Organic Light Emitting Diode) display panel, a QLED (Quantum Dot Light Emitting Diodes) display panel, or the like. Embodiments of the present disclosure do not make specific limitations on this. For example, the display panel 1 in embodiments of the present disclosure is an OLED display panel.

[0056] For example, the display panel 1 can be a flexible folding display panel. The flexible folding display panel is a display panel with folding function, which can be folded under the action of external force, and can also be restored to a flat state under the action of external force.

[0057] For example, the flexible folding display panel can be an outer folding display panel or an inner folding display panel, and embodiments of the present disclosure do not make limitations on this. The outer folding display panel refers to that the display side of the flexible folding display panel faces outward in the folded state, thereby being able to provide convenient services for customers. The inner folding display panel refers to that the display side of the flexible folding display panel faces inward in the folded state, thereby being able to well avoid the generation of scratches and other bad conditions of the flexible folding display panel. In embodiments of the present disclosure, the flexible folding display panel is exemplarily described as an inner folding display panel.

[0058] In addition, in the case that the flexible folding display panel can be folded multiple times, the flexible folding display panel can simultaneously include an inner folding area and an outer folding area.

[0059] Specifically, as shown in FIGS. 2 and 3, the display panel 1 includes at least one bending part 10 and at least two non-bending parts 11, and two adjacent non-bending parts 11 are connected by one bending part 10.

[0060] For example, as shown in FIG. 2, the display panel 1 includes one bending part 10 and two non-bending parts 11. At this time, the display panel 1 can be folded once.

[0061] For example, as shown in FIG. 2, the display panel 1 includes one bending part 10 and two non-bending parts 11. At this time, the display panel 1 can be folded once.

[0062] For example, as shown in FIG. 3, the display panel 1 includes two bending parts 10 and three non-bending parts 11. At this time, the display panel 1 can be folded twice.

[0063] In some examples, as shown in FIG. 2, the support 2' is arranged on the non-display side of the display panel 1. Among them, the side of the display panel 1 for displaying images is the display side of the display panel 1, and the side facing away from the display side of the display panel 1 is the non-display side of the display panel 1.

[0064] The support 2' is used to support the display panel 1.

[0065] Exemplarily, the material of the support 2' can be metal, for example, stainless steel SUS or titanium alloy, etc. Exemplarily, the material of the support 2' is non-metal, for example, plastic, glass fiber composite material or carbon fiber composite material, etc. The embodiments of the present disclosure do not make any limitation in this regard.

[0066] The above-mentioned materials have the characteristics of large Young's modulus and good support effect. In the case of selecting the above-mentioned materials for the support 2', the effective support of the display panel 1 can be realized, and the reliability of the display module 100 is improved. Among them, the Young's modulus can refer to the physical quantity of the resistance of the component to deformation. The larger the Young's modulus, the stronger the resistance to deformation, and the part is less likely to bend. The smaller the Young's modulus, the weaker the resistance to deformation, and the part is more likely to bend.

[0067] The large Young's modulus of the above-mentioned materials leads to poor bending performance of the support 2'. In order to improve the bending performance of the part of the support 2' corresponding to the bending part 10, as shown in FIG. 2, the part of the support 2' corresponding to the bending part 10 is designed with a hole.

[0068] Specifically, as shown in FIG. 2, the part of the support 2' corresponding to the bending part 10 is provided with a plurality of holes (for example, the plurality of holes can be through holes and / or blind holes). Thus, the part of the support 2' corresponding to the bending part 10 can have good bending performance, so as to drive the display panel 1 to bend, and make the display panel 1 meet the design requirements of bending.

[0069] Exemplarily, the plurality of through holes and the plurality of blind holes can be formed by etching or laser cutting process, etc.

[0070] It should be noted that due to the limitation of etching process or laser cutting process, in the case that the thickness of the support 2' is greater than 150 μm, the plurality of through holes cannot be formed by etching process or laser cutting process. Therefore, in order to form the plurality of through holes to make the part of the support 2' corresponding to the bending part 10 have good bending performance, the thickness of the support 2' is less than or equal to 150 μm.

[0071] In some examples, as shown in FIG. 2, the display module 100 further comprises a spacing layer 3 arranged between the display panel 1 and the support 2'.

[0072] Exemplarily, the spacing layer 3 comprises a first adhesive layer 31, a second adhesive layer 33, and a substrate layer 32 between the first adhesive layer 31 and the second adhesive layer 33. The first adhesive layer 31 is bonded to the support 2', and the second adhesive layer 33 is bonded to the display panel 1.

[0073] The material of the first adhesive layer 31 and the material of the second adhesive layer 33 can be OCA (Optically Clear Adhesive). The material of the substrate layer 32 can include PI (Polyimide) or PET (Polyethylene Terephthalate).

[0074] Exemplarily, the thickness of the first adhesive layer 31 and the second adhesive layer 33 can be 20 μm. The thickness of the substrate layer 32 can be 25 μm.

[0075] It can be understood that the support 2' and the spacing layer 3 can jointly serve as a support structure to support the display panel 1.

[0076] In some examples, as shown in FIG. 4, the display module 100 further comprises a cover plate 4 and a cover layer 5.

[0077] The cover plate 4 is located on the display side of the display panel 1. The cover plate 4 serves as a surface structure of the display module 100, which can protect the display panel 1 below, prevent impurities from entering the display panel 1, and improve the drop resistance and impact resistance of the display panel 1, so that the surface of the display panel 1 is not easily scratched or damaged.

[0078] The cover layer 5 is located on the side of the cover plate 4 away from the display panel 1. For example, the material of the cover layer 3 can include CPI (Colorless polyimide), which has high hardness, scratch resistance, and impact resistance, and can improve the impact resistance and scratch resistance of the display module 100.

[0079] In some examples, as shown in FIG. 4, the display module 100 further comprises a middle frame 6. The cross-sectional shape of the middle frame 6 is substantially "L" shaped. The middle frame 6 is installed at the edge of the support 2', and the part of the support 2' away from the display panel 1 abuts against the middle frame 6. Thus, the middle frame 6 and the above-mentioned support structure jointly support the display panel 1 and some film layers (for example, the cover plate 4 and the cover layer 5 shown in FIG. 4) disposed on the display panel 1.

[0080] Exemplarily, the material of the middle frame 6 can include hard plastic or aluminum alloy.

[0081] It can be understood that, in the case that the thickness of the support 2' is limited, the middle frame 6 needs to be thick to ensure better support effect on the display panel 1 and some film layers arranged on the display panel 1.

[0082] When the middle frame 6 is thick, it occupies a large space of the whole machine, resulting in that the display module 100 is thick as a whole. Moreover, in the case that the display area of the foldable display module 100 is large, the power consumption of the display module 100 is relatively high, and a battery with large capacity is needed to support the large power consumption. The thick middle frame 6 occupies a large space of the whole machine, and the space for accommodating the battery in the display device 2000 is small, thereby affecting the endurance time of the display device 2000.

[0083] Therefore, in the embodiments of the present disclosure, the support is improved, as shown in FIG. 5. The display module 100 includes the display panel 1 and the support 2. The support 2 is arranged on the non-display side of the display panel 1.

[0084] As shown in FIG. 5, the support 2 includes at least one bending area 20 and at least one non-bending area 21. The bending area 20 corresponds to one bending portion 10 of the display panel 1, and the non-bending area 21 corresponds to one non-bending portion 11 of the display panel 1.

[0085] It should be noted that the above-mentioned "the bending area 20 corresponds to one bending portion 10 of the display panel 1" means that, in the thickness direction of the display module 100, the part of the support 2 corresponding to one bending area 20 at least partially overlaps with one bending portion 10 of the display panel 1. Thus, it is beneficial to improve the flexibility of the display module 100.

[0086] For example, the orthographic projection of the part of the support 2 corresponding to one bending area 20 on the display panel 1 is located in one bending portion 10, and overlaps with the boundary of one bending portion 10. For another example, the orthographic projection of the part of the support 2 corresponding to one bending area 20 on the display panel 1 is located in one bending portion 10, and has a spacing with the boundary of one bending portion 10. For another example, in the orthographic projection of the part of the support 2 corresponding to one bending area 20 on the display panel 1, part of the orthographic projection is located in one bending portion 10, and part of the orthographic projection is located in a non-bending portion 11 adjacent to the bending portion 10. The embodiments of the present disclosure do not make any limitation in this regard.

[0087] It should be noted that the above-mentioned "the non-bending area 21 corresponds to one non-bending portion 11 of the display panel 1" means that the part of the support 2 corresponding to one non-bending area 21 at least partially overlaps with one non-bending portion 11 of the display panel 1. Thus, it is beneficial to improve the support effect of the support 2 on the non-bending portion 11 of the display panel 1.

[0088] For example, the orthographic projection of the portion of the support 2 corresponding to a non-bending region 21 on the display panel 1 is located within a non-bending portion 11 and overlaps the boundary of the non-bending portion 11. For another example, the orthographic projection of the portion of the support 2 corresponding to a non-bending region 21 on the display panel 1 is located within a non-bending portion 11 and has a spacing from the boundary of the non-bending portion 11. For yet another example, the orthographic projection of the portion of the support 2 corresponding to a non-bending region 21 on the display panel 1 has a portion located within a non-bending portion 11 and a portion located within a bending portion 10 adjacent to the non-bending portion 11. Embodiments of the present disclosure do not limit this.

[0089] As shown in FIG. 5, the bending groove 210 is provided in at least the bending region 20 of the support 2, the bending groove 210 comprises a first bending pattern 211 and a second bending groove 212 arranged in layers, the orthographic projection of the second bending groove 212 on the display panel 1 covers the orthographic projection of the first bending pattern 211 on the display panel 1, the first bending pattern 211 comprises at least one opening 2110, and the area of the orthographic projection of the opening 2110 on the display panel 1 is smaller than the area of the orthographic projection of the second bending groove 212 on the display panel 1.

[0090] In some examples, the bending groove 210 is provided in the bending region 20. In other examples, the bending groove 210 is provided in the bending region 20 and also provided in a non-bending region 21 adjacent to the bending region 20.

[0091] In some examples, the first bending pattern 211 is closer to the display panel 1 than the second bending groove 212, as shown in FIG. 4. In other examples, the first bending pattern 211 is farther from the display panel 1 than the second bending groove 212. Embodiments of the present disclosure do not limit this.

[0092] For example, as shown in FIG. 5, the opening 2110 extends along the thickness direction of the support 2 from the bottom surface of the second bending groove 212.

[0093] For example, the shape, number, depth and arrangement of the opening 2110 can be selected according to actual conditions, and embodiments of the present disclosure do not limit this.

[0094] For example, the opening 2110 can be a through hole or a blind hole. Embodiments of the present disclosure do not limit this.

[0095] For example, the first bending pattern 211 can comprise a plurality of openings 2110. In the case where the first bending pattern 211 comprises a plurality of openings 2110, the plurality of openings 2110 can be arranged in an array shape, thereby making the bending performance of the portion of the support 2 corresponding to the bending region 20 better and more stable.

[0096] The shape of the orthographic projection of each opening 2110 along the thickness direction of the display module 100 can be rectangular, circular, diamond-shaped, or other irregular shapes. Embodiments of the present disclosure do not limit this.

[0097] The shape of the cross section of each opening 2110 is rectangular, semicircular, semi-elliptical, trapezoidal, triangular, or other irregular shapes, which is a cross section parallel to the axis direction of the hole.

[0098] With the above arrangement, at least a portion of the support member 2 corresponding to the bending area 20 is first provided with the second bending groove 212, and then the first bending pattern 211 is provided, that is, the support member 2 is patterned in two parts. Therefore, the limitation of the etching process or the laser cutting process can be overcome (that is, for example, when the thickness of the support member 2 is greater than 150 μm, a plurality of through holes cannot be formed by the etching process or the laser cutting process), the overall thickness of the support member 2 is set to be thicker (for example, the thickness of the support member 2 can be greater than 150 μm), thereby improving the support performance of the support member 2 and reducing the risk of display abnormalities of the display panel 1 due to insufficient support of the support member 2. At the same time, the portion of the support member 2 corresponding to the bending area 20 includes the first bending pattern 211 and the second bending groove 212 arranged in layers, so that the portion of the support member 2 corresponding to the bending area 20 has good bending performance, thereby driving the display panel 1 to bend and meeting the design requirements of the display panel 1.

[0099] In addition, as known from the above, the middle frame 6 and the support member 2 jointly support the display panel 1 and some film layers arranged on the display panel 1. In the above arrangement, the limitation of the etching process or the laser cutting process is overcome, the support member 2 is set to be thicker, and the support performance of the support member 2 is improved. In this case, the thickness of the middle frame 6 can be relatively reduced. In the case where the material of the support member 2 is metal and the material of the middle frame 6 includes hard plastic or aluminum alloy, due to the difference in material, the thickness of the support member 2 increases a little, and the thickness of the middle frame 6 relatively reduces more, which is beneficial to realize the thinning of the display module 100, and the middle frame 6 occupies less space in the whole machine, and relatively, the space for accommodating the battery in the display device 2000 increases, and a larger number of battery blocks can be accommodated, thereby improving the endurance time of the display device 2000.

[0100] It should be noted that there are many ways to arrange the support member 2, which can be selected according to actual needs.

[0101] In one implementation manner, the support member 2 is a single-layer structure.

[0102] In other implementation manners, the support member 2 is a multi-layer structure.

[0103] In some embodiments, as shown in FIG. 5, the support 2 is a single-layer structure, and the second bending groove 212 is recessed from one side surface to the other side surface of the support 2 in the thickness direction, and extends along the first direction X. The first direction X is the arrangement direction of the bending area 20 and the non-bending area 21.

[0104] In some examples, the support 2 is recessed from the surface close to the display panel 1 to the surface away from the display panel 1 to form the second bending groove 212. In other examples, the support 2 is recessed from the surface away from the display panel 1 to the surface close to the display panel 1 to form the second bending groove 212, as shown in FIG. 5.

[0105] With the above arrangement, the part of the support 2 corresponding to the bending area 20 forms the second bending groove 212, which can reduce the thickness of the part of the support 2 corresponding to the bending area 20, reduce the stress on the part of the support 2 corresponding to the bending area 20 when the support 2 is bent, reduce the risk of breaking of the part of the support 2 corresponding to the bending area 20, and improve the bending performance of the part of the support 2 corresponding to the bending area 20. On the other hand, the part of the support 2 corresponding to the non-bending area 21 can have a larger thickness, so as to ensure that the support 2 has good supporting performance.

[0106] In some embodiments, as shown in FIG. 5 and FIG. 6, the at least one bending area 20 includes a first bending area 201, and when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, the non-bending areas 21 adjacent to the two sides of the first bending area 201 are located outside the non-bending parts 11 adjacent to the two sides of the bending part 10. Specifically, when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, the display side of the display panel 1 faces inwards, and the part of the support 2 corresponding to the first bending area 201 is located outside the display panel 1. That is, the bending part 10 of the display panel 1 corresponding to the first bending area 201 is wrapped by the part of the support 2 corresponding to the first bending area 201.

[0107] As shown in FIG. 5 and FIG. 6, the first bending area 201 includes a first bending sub-area 2011, two inclined plate areas 2013, and two second bending sub-areas 2012; the two inclined plate areas 2013 are connected to the two sides of the first bending sub-area 2011 respectively, and the side of each inclined plate area 2013 away from the first bending sub-area 2011 is connected to one second bending sub-area 2012, and the side of the second bending sub-area 2012 away from the inclined plate area 2013 is connected to the non-bending area 21; the first bending sub-area 2011 and / or the second bending sub-area 2012 is / are provided with a plurality of openings 2110.

[0108] For example, as shown in FIG. 6, when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, the first bending sub-area 2011 and the second bending sub-area 2012 are in the bending state, and the two inclined plate areas 2013 are in the flat state.

[0109] In addition, when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, the inclined plate area 2013 has a certain inclination angle. For example, the inclined plate area 2013 has an included angle between the extension line and the extension line of the non-bending area 21.

[0110] Specifically, as shown in FIGS. 5 and 6, when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, in the support 2, the first bending sub-area 2011 is bent inward, for example, the first bending sub-area 2011 is bent in a circular arc shape and protrudes towards the side away from the display panel 1; the second bending sub-area 2012 is bent outward, for example, the second bending sub-area 2012 is bent in a circular arc shape and protrudes towards the side close to the display panel 1. The bending area 20 is bent as a whole in a water drop profile shape, as shown in FIG. 6.

[0111] It should be noted that the above-mentioned "the first bending sub-area 2011 and / or the second bending sub-area 2012 is provided with a plurality of openings 2110" means that in some examples, the first bending sub-area 2011 is provided with a plurality of openings 2110; in other examples, the second bending sub-area 2012 is provided with a plurality of openings 2110; in yet other examples, the first bending sub-area 2011 and the second bending sub-area 2012 are both provided with a plurality of openings 2110, as shown in FIG. 5.

[0112] In addition, when the first bending sub-area 2011 is provided with a plurality of openings 2110, the plurality of openings 2110 can all be through holes, and the plurality of through holes can be arranged in an array shape, as shown in FIG. 5. When the second bending sub-area 2012 is provided with a plurality of openings 2110, the plurality of openings 2110 can all be blind holes, and the plurality of blind holes can be arranged in an array shape, as shown in FIG. 5.

[0113] In this embodiment, by providing a plurality of openings 2110 in the first bending area 201, when the display panel 1 is folded along the bending part 10 corresponding to the first bending area 201, the stress on the part of the support 2 corresponding to the first bending area 201 in the bending process can be reduced, the flexibility of the part of the support 2 corresponding to the first bending area 201 can be improved, and the display module 100 is more easily bent.

[0114] In some embodiments, as shown in FIG. 5, the inclined plate area 2013 is not provided with openings 2110. That is, the thickness of the inclined plate area 2013 is uniform.

[0115] As can be seen from the above, in the case of relative folding of the display module 100, the two inclined plate regions 2013 are in a flat state, that is, the part of the support 2 corresponding to the inclined plate region 2013 is not stressed.

[0116] In this embodiment, in the first bending region 201, the inclined plate region 2013 is not provided with the opening 2110, and the first bending sub-region 2011 and / or the second bending sub-region 2012 are provided with a plurality of openings 2110, so as to not only be able to guarantee that the part of the support 2 corresponding to the first bending region 201 has good bending performance, but also be able to improve the supporting performance of the support 2 to a certain extent.

[0117] In some embodiments, as shown in FIG. 5, the second bending groove 212 provided by the first bending region 201 has a groove back away from the display panel 1. That is, the part of the support 2 corresponding to the first bending region 201 is away from the surface of the display panel 1, and the surface of the support 2 close to the surface of the display panel 1 is recessed to form the second bending groove 212.

[0118] It should be noted that when the display panel 1 is folded along the bending part 10 corresponding to the first bending region 201, the display side of the display panel 1 faces inwards, and the part of the support 2 corresponding to the bending region 20 is located on the outside of the display panel 1. At this time, in the part of the support 2 corresponding to the first bending region 201, the surface away from the display panel 1 is under tensile stress, and the surface close to the display panel 1 is under compressive stress. It can be understood that in the case of relative folding of the display module 100, the surface of the support 2 under tensile stress has a greater impact on the bending performance of the support 2.

[0119] In this embodiment, by providing the second bending groove 212 on the side under tensile stress in the part of the support 2 corresponding to the first bending region 201, the bending performance of the part of the support 2 corresponding to the first bending region 201 can be greatly improved.

[0120] In some embodiments, as shown in FIG. 7, the second bending groove 212 provided in the first bending region 201 is also located in the non-bending region 21 close to the first bending region 201.

[0121] For example, the second bending groove 212 can be formed in the first bending region 201 and the non-bending region 21 close to the first bending region 201 by etching process or laser cutting process.

[0122] In addition, in the case where the second bending groove 212 is located in both the first bending region 201 and the non-bending region 21 close to the first bending region 201, the first bending pattern 211 can be located only in the first bending region 201. In this way, the part of the support 2 corresponding to the non-bending region 21 can have good supporting performance.

[0123] In some embodiments, as shown in FIGS. 7 and 8, the at least one bending region 20 further comprises a second bending region 202, when the display panel 1 is folded along the bending portion 10 corresponding to the second bending region 202, the non-bending regions 21 adjacent to the two sides of the second bending region 202 are located inside the non-bending portions 11 adjacent to the two sides of the bending portion 10. Specifically, when the display panel 1 is folded along the bending portion 10 corresponding to the second bending region 202, the display side of the display panel 1 faces outward, and the portion of the support 2 corresponding to the second bending region 202 is located inside the display panel 1. That is, the bending portion 10 in the display panel 1 corresponding to the second bending region 202 is wrapped by the portion of the support 2 corresponding to the second bending region 202.

[0124] As can be seen from the above, the bending region 20 of the support 2 corresponds to one bending portion 10 of the display panel 1, and the support 2 can drive the display panel 1 to fold twice when the support 2 comprises the first bending region 201 and the second bending region 202, and the display panel 1 comprises two bending portions 10. Among them, the bending portion 10 in the display panel 1 corresponding to the first bending region 201 of the support 2 is folded inward, and the bending portion 10 in the display panel 1 corresponding to the second bending region 202 of the support 2 is folded outward.

[0125] In addition, for the support 2, the first bending region 201 and the second bending region 202 are both provided with a bending groove 210, so that the portion of the support 2 corresponding to the first bending region 201 and the second bending region 202 has good bending performance; avoid the support 2 from being broken when folding or bending; at least one or more non-bending regions 21 in the support 2 can have a larger thickness, so as to ensure the supporting performance of the support 2, thereby realizing stable support of the display panel 1.

[0126] In some embodiments, as shown in FIG. 9, the notch of the second bending groove 212 provided by the second bending region 202 faces the display panel 1. That is, the portion of the support 2 corresponding to the second bending region 202, the surface of the support 2 close to the display panel 1 is recessed to form the second bending groove 212 away from the surface of the display panel 1.

[0127] It should be noted that when the display panel 1 is folded along the bending portion 10 corresponding to the second bending region 202, the display side of the display panel 1 faces outward, and the portion of the support 2 corresponding to the bending region 20 is located inside the display panel 1. At this time, in the portion of the support 2 corresponding to the second bending region 202, the surface close to the display panel 1 is subjected to tensile stress, and the surface away from the display panel 1 is subjected to compressive stress.

[0128] Since the surface of the support 2 subjected to tensile stress has a great influence on the bending performance of the support 2 in the case of relative folding of the display module 100, in the embodiment, the second bending groove 212 is arranged on the side subjected to tensile stress in the part of the support 2 corresponding to the second bending area 202, so that the bending performance of the part of the support 2 corresponding to the second bending area 202 can be greatly improved.

[0129] Of course, in other embodiments, the notch of the second bending groove 212 arranged by the second bending area 202 faces away from the display panel 1. That is, the surface of the support 2 away from the display panel 1 in the part of the support 2 corresponding to the second bending area 202 is recessed to form the second bending groove 212 towards the surface of the support 2 close to the display panel 1, as shown in FIGS. 7 and 8.

[0130] In some embodiments, as shown in FIG. 10, the second bending groove 212 arranged in the first bending area 201 is in communication with the second bending groove 212 arranged in the second bending area 202.

[0131] For example, the notch of the second bending groove 212 arranged in the first bending area 201 and the notch of the second bending groove 212 arranged in the second bending area 202 both face away from the display panel 1, as shown in FIG. 9.

[0132] For example, the orthographic projection of the second bending groove 212 on the display panel 1 also covers the non-bending area 21 between the first bending area 201 and the second bending area 202.

[0133] With the above arrangement, the second bending groove 212 can be formed by one etching process, thereby simplifying the preparation process of the support 2.

[0134] In some embodiments, as shown in FIG. 11, the second bending groove 212 arranged in the second bending area 202 is also located in the non-bending area 21 close to the second bending area 202.

[0135] For example, the second bending groove 212 can be formed in the second bending area 202 and the non-bending area 21 close to the second bending area 202 by an etching process or a laser cutting process.

[0136] In addition, in the case where the second bending groove 212 is located in both the second bending area 202 and the non-bending area 21 close to the second bending area 202, the first bending pattern 211 can be located only in the second bending area 202. In this way, the part of the support 2 corresponding to the non-bending area 21 can have good support performance.

[0137] In some embodiments, as shown in FIGS. 12 and 13, the support 2 is a multi-layer structure, and the support 2 includes a support plate 22 and a reinforcing layer 23. The support plate 22 is located on the non-display side of the display panel 1. The reinforcing layer 23 is located on the side of the support plate 22 away from the display panel 1.

[0138] As shown in FIGS. 12 and 13, the support plate 22 is provided with at least one opening 2110 corresponding to the first bending area 201. The reinforcing layer 23 includes a plurality of reinforcing portions 231 discontinuous with each other in the first direction X, and a first gap 2311 is present between two adjacent reinforcing portions 231, and the first gap 2311 is provided corresponding to the first bending area 201.

[0139] For example, the thickness of the support plate 22 can be 150 μm, 140 μm, 130 μm, 120 μm, 110 μm, etc. In this way, a plurality of openings 2110 can be formed on the support plate by etching or laser cutting processes.

[0140] For example, the material of the support plate 22 can be metal, such as stainless steel SUS or titanium alloy, etc. For another example, the material of the support plate 22 is non-metal, such as plastic, glass fiber composite material or carbon fiber composite material, etc. The embodiments of the present disclosure do not limit this.

[0141] For example, the material of the reinforcing layer 23 can include a non-metal material that is easy to absorb water. The non-metal material can be at least one of polyimide (PI) material, graphite, polyethylene terephthalate (PET), etc. For another example, the reinforcing layer 23 can include a stainless steel layer.

[0142] In some examples, as shown in FIGS. 12 and 13, the support 2 further includes a connecting layer 24 between the support plate 22 and the reinforcing layer 23. The connecting layer 24 can be PSA (Pressure Sensitive Adhesive), double-sided tape, etc. The support plate 22 and the reinforcing layer 23 are bonded together through the connecting layer 24.

[0143] In addition, the connecting layer 24 can be provided with a gap. The gap of the connecting layer 24 is arranged opposite to the first gap 2311 of the reinforcing layer 23. For example, the orthographic projection of the gap of the connecting layer 24 on the display panel 1 can overlap the orthographic projection of the first gap 2311 of the reinforcing layer 23 on the display panel 1.

[0144] In this embodiment, by arranging the reinforcing layer 23 on the side of the support plate 22 away from the display panel 1, the support performance of the support member 2 corresponding to the part of the non-bending area 21 is enhanced, thereby realizing stable support of the display panel 1. Moreover, the reinforcing layer 23 is arranged with the first gap 2311 corresponding to the first bending area 201, thereby ensuring that the support member 2 as a whole has good bending performance corresponding to the part of the first bending area 201.

[0145] In addition, as known from the above, the middle frame 6 and the support member 2 jointly complete the support of the display panel 1 and some film layers arranged on the display panel 1. In the case where the support performance of the support member 2 corresponding to the part of the non-bending area 21 is improved, when the display device 2000 is bent as a whole, the support stress can be transferred to the support member 2, and the support stress borne by the middle frame 6 is relatively reduced, so that the thickness of the middle frame 6 can be relatively reduced. The space occupied by the middle frame 6 in the whole machine is reduced, and relatively, the space for accommodating the battery in the display device 2000 is increased, and a larger number of battery blocks can be accommodated, thereby improving the endurance time of the display device 2000 and improving the product competitiveness of the display device 2000.

[0146] In some embodiments, as shown in FIG. 13, the two reinforcing parts 231 on both sides of the first gap 2311 form the second bending groove 212 corresponding to the part of the first gap 2311, and the at least one opening 2110 is located at the bottom of the second bending groove 212 and formed on the support plate 22.

[0147] For example, the overall thickness of the support plate 22 is uniform. The thickness of the part of the support plate 22 corresponding to the first gap 2311 is equal to the thickness of the part of the support plate 22 corresponding to other parts.

[0148] For example, in the case where the support member 2 further comprises a connecting layer 24 between the support plate 22 and the reinforcing layer 23, there is a gap at the position of the connecting layer 24 corresponding to the first gap 2311, and the part of the connecting layer 24 corresponding to the gap constitutes a part of the second bending groove 212.

[0149] With the above arrangement, without changing the support plate 22, the support performance of the support member 2 corresponding to the part of the non-bending area 21 is further enhanced by arranging the reinforcing layer 23, thereby realizing stable support of the display panel 1.

[0150] In some embodiments, as shown in FIG. 12, the two reinforcing parts 231 on both sides of the first gap 2311 form the second bending groove 212 corresponding to the part of the first gap 2311 and the part of the support plate 22 corresponding to the first gap 2311, and the at least one opening 2110 is located at the bottom of the second bending groove 212 and formed on the support plate 22.

[0151] For example, the thickness of the portion of the support plate 22 corresponding to the first gap 2311 is reduced. That is, the thickness of the portion of the support plate 22 corresponding to the first gap 2311 is less than the thickness of the portion of the support plate 22 corresponding to other portions,

[0152] For example, the portion of the support plate 22 corresponding to the first gap 2311 can be provided with a groove (the portion of the support plate 22 corresponding to the first gap 2311 is recessed towards the surface of the display panel 1 away from the surface of the display panel 1, and the groove is formed), and the groove and the two reinforcing portions 231 corresponding to the portion of the first gap 2311 together form the second bending groove 212.

[0153] In addition, the orthographic projection of the two adjacent reinforcing portions 231 corresponding to the portion of the first gap 2311 on the display panel 1 can completely overlap the orthographic projection of the groove provided on the portion of the support plate 22 corresponding to the first gap 2311 on the display panel 1.

[0154] With the above arrangement, by providing a groove on the portion of the support plate 22 corresponding to the first gap 2311, the thickness of the portion of the support plate 22 corresponding to the first gap 2311 is reduced, and the bending performance of the portion of the support plate 22 corresponding to the first gap 2311 is further improved.

[0155] In some embodiments, as shown in FIG. 14, the at least one bending area 20 further includes a second bending area 202; the portion of the support plate 22 corresponding to the second bending area 202 is provided with at least one opening 2110; there is a second gap 2312 between the two adjacent reinforcing portions 231, and the second gap 2312 is provided corresponding to the second bending area 202.

[0156] For example, in the case where the support 2 further includes a connecting layer 24 located between the support plate 22 and the reinforcing layer 23, the connecting layer 24 is provided with a gap at a position corresponding to the second bending area 202, and the gap of the connecting layer 24 is provided corresponding to the second gap 2312 of the reinforcing layer 23. For example, the orthographic projection of the gap of the connecting layer 24 at the position corresponding to the second bending area 202 on the display panel 1 can overlap the orthographic projection of the second gap 2312 of the reinforcing layer 23 on the display panel 1.

[0157] For example, in the case where the at least one bending area 20 further includes a second bending area 202, the thickness of the support plate 22 can be uniform or non-uniform. Embodiments of the present disclosure do not limit this.

[0158] For example, the thickness of the support plate 22 is non-uniform. Specifically, the portion of the support plate 22 corresponding to the second bending area 202 can be provided with a second bending groove 212, and the at least one opening 2110 is located at the bottom of the second bending groove 212.

[0159] For example, the thickness of the support plate 22 is uniform. The two reinforcing portions 231 on both sides of the second gap 2312 form a second bending groove 212 corresponding to the second gap 2312, and the at least one opening 2110 is located at the bottom of the second bending groove 212.

[0160] In this embodiment, the reinforcing layer 23 is arranged on the side of the support plate 22 away from the display panel 1, so as to strengthen the support performance of the support 2 corresponding to the part of the non-bending area 21, thereby realizing stable support of the display panel 1. On the position of the reinforcing layer 23 corresponding to the second bending area 202, the second gap 2312 is arranged to ensure that the part of the support 2 corresponding to the second bending area 202 has good bending performance.

[0161] In some embodiments, as shown in FIG. 14, the two reinforcing portions 231 on both sides of the second gap 2312 form a second bending groove 212 corresponding to the second gap 2312, and the at least one opening 2110 is located at the bottom of the second bending groove 212 and formed on the support plate 22.

[0162] For example, the overall thickness of the support plate 22 is uniform. The thickness of the part of the support plate 22 corresponding to the second gap 2312 is equal to the thickness of the part of the support plate 22 corresponding to other parts.

[0163] For example, in the case that the support 2 further comprises a connecting layer 24 between the support plate 22 and the reinforcing layer 23, there is a gap at the position of the connecting layer 24 corresponding to the second gap 2312, and the part of the connecting layer 24 corresponding to the gap constitutes a part of the second bending groove 212.

[0164] With the above arrangement, without changing the support plate 22, the support performance of the part of the support 2 corresponding to the second bending area 202 is further strengthened by arranging the reinforcing layer 23, thereby realizing stable support of the display panel 1.

[0165] In some embodiments, the two reinforcing portions 231 on both sides of the second gap 2312 form a second bending groove 212 corresponding to the second gap 2312 and the part of the support plate 22 corresponding to the second gap 2312, and the at least one opening 2110 is located at the bottom of the second bending groove 212 and formed on the support plate 22.

[0166] For example, the thickness of the part of the support plate 22 corresponding to the second gap 2312 is thinned. That is, the thickness of the part of the support plate 22 corresponding to the second gap 2312 is less than the thickness of the part of the support plate 22 corresponding to other parts,

[0167] For example, the portion of the support plate 22 corresponding to the second gap 2312 can be provided with a groove (the portion of the support plate 22 corresponding to the second gap 2312, the surface of the support plate 22 away from the display panel 1, the surface of the support plate 22 close to the display panel 1 is recessed to form the groove), which is formed together with the portions of the two reinforcing portions 231 on both sides of the second gap 2312 corresponding to the second gap 2312 to form the second bending groove 212.

[0168] In addition, the orthographic projection of the portions of the two adjacent reinforcing portions 231 corresponding to the second gap 2312 on the display panel 1 can completely overlap the orthographic projection of the groove provided by the portion of the support plate 22 corresponding to the second gap 2312 on the display panel 1.

[0169] With the above arrangement, by providing a groove on the portion of the support plate 22 corresponding to the second gap 2312, the thickness of the portion of the support plate 22 corresponding to the second gap 2312 is reduced, and the bending performance of the portion of the support plate 22 corresponding to the second gap 2312 is further improved.

[0170] In some embodiments, as shown in FIG. 15, the display module 100 further includes an adhesive layer 7 located between the support 2 and the display panel 1; the adhesive layer 7 includes sub-portions 71 that are disconnected from each other in the first direction X, and there is a third gap 711 between two adjacent sub-portions 71 of the adhesive layer 7, which is provided corresponding to the second bending area 202.

[0171] For example, the orthographic projection of the third gap 711 on the display panel 1 at least partially overlaps the orthographic projection of the second bending area 202 on the display panel. For example, the orthographic projection of the third gap 711 on the display panel 1 is located within the orthographic projection of the second bending area 202 on the display panel, and overlaps the boundary of the orthographic projection of the second bending area 202 on the display panel.

[0172] The support 2 and the display panel 1 are bonded by the adhesive layer 7.

[0173] For example, the material of the adhesive layer 7 can be OCA (Optically Clear Adhesive, optically clear adhesive). That is, the adhesive layer 7 is formed after the optical adhesive is cured; the optical adhesive is, for example, viscous. Therefore, during the process of bonding the support 2 and the display panel 1 by the adhesive layer 7, there will be a certain overflow of the adhesive layer 7.

[0174] With the above arrangement, the support 2 and the display panel 1 can be bonded, and the above-mentioned third gap 711 can serve as a overflow landing of the optical adhesive on both sides of the third gap 711. During the formation of the adhesive layer 7, the optical adhesive can overflow at the third gap 711, thereby avoiding the accumulation of adhesive.

[0175] In some embodiments, the thickness of the portion of the support 2 corresponding to the one or more non-bending regions 21 is greater than or equal to 150 pm. For example, the thickness of the portion of the support 2 corresponding to the one or more non-bending regions 21 can be 150 pm, 180 pm, 210 pm, 250 pm, 300 pm, etc. Embodiments of the present disclosure do not limit this.

[0176] For example, in the case where the thickness of the portion of the support 2 corresponding to the one or more non-bending regions 21 is 300 pm, the overall thickness of the portion of the support 2 corresponding to the bending region 20 can range from 100 pm to 150 pm.

[0177] It can be understood that the rigidity = material thickness * material elastic modulus.

[0178] Under the premise that the material of the support 2 is certain, the rigidity of the support 2 is positively correlated with the thickness of the support 2. That is, as the thickness of the support 2 increases, the rigidity of the support 2 increases; as the thickness of the support 2 decreases, the rigidity of the support 2 decreases. For example, in the case where the thickness of the support 2 increases from 100 pm to 300 pm, the rigidity of the support 2 is improved by 3 times.

[0179] Wherein, the rigidity can be understood as the ability to resist deformation under external force, the greater the rigidity of the support 2, the better the support performance of the support 2.

[0180] In the present embodiment, the thickness of the support 2 is set to be relatively thick, thereby ensuring the support performance of the support 2, thereby realizing stable support of the display panel 1; at the same time, the second bending groove 212 is first provided in the portion of the support 2 corresponding to the bending region 20, and the portion of the support 2 corresponding to the bending region 20 is thinned to improve the bending performance of the portion of the support 2 corresponding to the bending region 20.
