Description

Display modules and display devices Technical Field

[0001] This application relates to the field of display technology, specifically to a display module and display device. Background Technology

[0002] Flexible screen support plates typically have holes punched in the bending areas to improve their bending capacity, but this also reduces their impact resistance. Existing support plate designs prioritize increasing bending capacity at the expense of impact resistance. To further improve impact resistance, current solutions involve simultaneously increasing the width of all ribs, which again reduces bending capacity, causes stress concentration at the apex of the holes, and can even lead to breakage.

[0005] The support plate includes multiple rows of openings disposed in the bending area, the multiple rows of openings being arranged along a first direction; each opening group has 2n-1 rows of openings, where n is a positive integer greater than 1, and the openings in each row of openings extend along a second direction and are arranged in a manner that intersects the first direction with the second direction;

[0006] In at least a portion of the bending region, in the first direction, the distance between two adjacent rows of openings is greater than the distance between two adjacent rows of openings in one opening group.

[0015] This application provides a support plate, a display module, and a display device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0016] On one hand, this application provides a display module, including a support plate and a flexible display panel disposed on the support plate. The support plate includes a bending area and a non-bending area, and the non-bending area is located on both sides of the bending area.

[0017] The support plate includes multiple rows of openings disposed in the bending area, the multiple rows of openings being arranged along a first direction; each opening group has 2n-1 rows of openings, where n is a positive integer greater than 1, and the openings in each row of openings extend along a second direction and are arranged in a manner that intersects the first direction with the second direction;

[0018] In at least a portion of the bending region, in the first direction, the distance between two adjacent rows of openings is greater than the distance between two adjacent rows of openings in one opening group.

[0019] Optionally, in some embodiments of this application, the bending area has a bending axis, and the number of the opening groups is 2m-1 rows, where m is a positive integer greater than 1;

[0020] In the top view of the support plate, the pattern of the bending area is a pattern symmetrically arranged about the bending axis, and the pattern of the m-th row of openings is a pattern symmetrically arranged about the bending axis.

[0021] Optionally, in some embodiments of this application, in at least a portion of the bending region, the distance between any two adjacent rows of the openings is equal in the first direction.

[0022] Optionally, in some embodiments of this application, in at least a portion of the bending region, the distance between two adjacent rows of openings decreases in the direction from the bending axis to the non-bending region.

[0023] Optionally, in some embodiments of this application, in the first direction, the distance between two adjacent rows of the opening groups is between 1.5 and 2 times the distance between two adjacent rows of the openings in one opening group.

[0024] Optionally, in some embodiments of this application, in at least a portion of the bending region, in the first direction, a first rib is connected between two adjacent rows of the opening groups, and the value of n is negatively correlated with the number of the first ribs.

[0025] Optionally, in some embodiments of this application, the bending area includes a first opening area and a second opening area disposed on both sides of the first opening area, the second opening area being disposed between the first opening area and the non-bending area, and the bending axis being located in the first opening area;

[0026] In the first opening area, in the first direction, the distance between two adjacent rows of opening groups is greater than the distance between two adjacent rows of openings in one opening group;

[0027] In the second opening area, in the first direction, the distance between two adjacent rows of opening groups is equal to the distance between two adjacent rows of openings in one opening group.

[0028] Optionally, in some embodiments of this application, in the top view of the support plate, in the first direction, a plurality of the openings are arranged in rows, and adjacent rows of the openings partially overlap each other, and the length direction of the openings is the second direction;

[0029] In the first opening area, the lengths of the openings in the same row are equal; in the second opening area, the lengths of the openings in the same row decrease in the direction from the first opening area toward the non-bending area.

[0030] Optionally, in some embodiments of this application, in a top view of the support plate, the support plate has a first side and a second side disposed opposite to each other, the first side and the second side are both perpendicular to the bending axis, and in the second direction, the first row of openings penetrates the first side and the last row of openings penetrates the second side; the distance between two adjacent openings in the second direction is greater than the distance between two adjacent rows of openings in the first direction.

[0031] Optionally, in some embodiments of this application, in a top view of the support plate, in the first direction, the width of the opening is between 0.08 mm and 0.2 mm; in the second direction, the distance between two adjacent openings is between 0.2 mm and 0.4 mm, and the length of the opening is between 4 mm and 9 mm; the two ends of the opening are semi-circular, and the radius of the semi-circle is half the width of the opening.

[0032] Optionally, in some embodiments of this application, the bending area includes an inner bending area, a transition area, and an outer bending area connected in sequence, the outer bending area is connected to the non-bending area, and the first opening area and the second opening area are located in the inner bending area;

[0033] Among them, the outer bending area, the transition area, and the inner bending area are partially non-opening areas near the transition area.

[0034] On the other hand, correspondingly, embodiments of this application also provide a display device, which includes a display module as described in any of the above embodiments.

[0035] The support plate of the display module in this embodiment includes multiple rows of openings disposed in the bending area. These multiple rows of openings are arranged along a first direction, and each opening group has 2n-1 rows of openings, where n is a positive integer greater than 1. The openings in each row extend and are arranged along a second direction, which intersects the first direction. In the first direction, the distance between two adjacent rows of openings is greater than the distance between two adjacent rows of openings in a single opening group.

[0036] It is understood that, in the first direction, the distance between two adjacent rows of openings is set to be greater than the distance between two adjacent rows of openings in one opening group, that is, to increase the rib width between the opening groups, thereby improving the impact resistance of the support plate, while the rib width within the opening group is smaller to meet the requirements for bending capacity.

[0037] In Figures 1 and 2, the first direction F1 can be a direction parallel to one side of the support plate 100 in the plan view, and for example, it can be the transverse direction of the support plate 100. The second direction F2 can be a direction parallel to the other side of the support plate 100 in the plan view. However, it is not limited to this; for example, the first direction F1 and the second direction F2 can also intersect non-perpendicularly.

[0038] It is understandable that the support plate 100 can be applied to teardrop-shaped folding flexible panels, but is not limited to this. For example, it can also be applied to inward-bending folding flexible panels or outward-bending folding flexible panels.

[0039] Optionally, in some embodiments of this application, the material of the support plate 100 may be stainless steel, titanium alloy, aluminum alloy, carbon fiber, etc.

[0040] This application provides a support plate 100 for supporting a flexible display panel. The support plate 100 includes a bending region wz and a non-bending region nw, with the non-bending region nw located on both sides of the bending region wz.

[0041] The support plate 100 includes a multi-row perforation group 10 disposed in the bending region wz, the multi-row perforation group 10 being arranged along a first direction F1. The perforation group 10 has 2n-1 rows of perforations 11, where n is a positive integer greater than 1. In each row of perforations 11, the perforations 11 extend along a second direction F2 and are arranged in a manner that intersects the first direction F1 and the second direction F2.

[0042] In at least a portion of the bending region, in the first direction F1, the distance Yp between two adjacent rows of openings 10 is greater than the distance Yc between two adjacent rows of openings 11 in an opening group 10.

[0043] It is understandable that the opening 11 penetrates the support plate 100 in the thickness direction. In the first direction F1, the distance Yp between two adjacent rows of opening groups 10 is set to be greater than the distance Yc between two adjacent rows of openings 11 in an opening group 10, that is, to increase the rib width between opening groups 10, thereby improving the impact resistance of the support plate 100, while the rib width within the opening group 10 is smaller to meet the requirements for bending capacity.

[0044] It should be noted that a first rib j1 connects two adjacent rows of openings 10, and a second rib j2 connects two adjacent rows of openings 11. The distance Yp between two adjacent rows of openings 10 is the width of the first rib j1 in the first direction F1, and the distance Yc between two adjacent rows of openings 11 in the opening group 10 is the width of the second rib j2 in the first direction F1. That is, the width of the first rib j1 is greater than the width of the second rib j2. The larger the width Yp of the first rib j1, the stronger the impact resistance of the support plate 100.

[0045] Secondly, the first rib j1 and the second rib j2 are non-perforated structures to ensure their impact resistance. Both the first rib j1 and the second rib j2 extend along the second direction F2. In the first direction F1, the first rib j1 and the perforated group 10 are alternately arranged to improve the uniformity of impact resistance.

[0046] Optionally, in some embodiments of this application, in the first direction F1, the distance Yp between two adjacent rows of opening groups 10 is between 1.5 and 2 times the distance Yc between two adjacent rows of openings 11 in an opening group 10.

[0047] It is understandable that the wider the first rib j1 and the second rib j2, the stronger the impact resistance of the support plate 100, but the weaker its bending performance. Therefore, in order to balance bending performance and impact resistance, the second rib j2 is kept relatively narrow and the first rib j1 is relatively wide, and the distance Yp is selected to be between 1.5 and 2 times the distance Yc, for example, it can be 1.5, 1.6, 1.7, 1.8, 1.9, or 2 times.

[0048] Optionally, in some embodiments of this application, in the first direction F1, the distance Yp between two adjacent rows of opening groups 10 is between 0.2 mm and 0.3 mm, and the distance Yc between two adjacent rows of openings 11 in an opening group 10 is between 0.1 mm and 0.2 mm.

[0049] That is to say, the width of the first rib j1 is between 0.2 mm and 0.3 mm, and the width of the second rib j2 is between 0.1 mm and 0.2 mm.

[0050] It is understandable that the wider the first rib j1 and the second rib j2, the stronger the impact resistance of the support plate 100, but the weaker its bending performance. Therefore, in order to balance bending performance and impact resistance, the distance Yp is selected to be between 0.2 mm and 0.3 mm, and the distance Yc is selected to be between 0.1 mm and 0.2 mm, so as to maximize the impact resistance while satisfying the bending performance.

[0051] Optionally, the distance Yp between two adjacent rows of openings 10 can be 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, or 0.3 mm. The distance Yc between two adjacent rows of openings 11 in an opening group 10 can be 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or 0.2 mm.

[0052] Optionally, in some embodiments of this application, the aperture group 10 has 2n-1 rows of apertures 11, where n is a positive integer greater than 1. That is, the number of rows of apertures 11 in an aperture group 10 is an odd number greater than 1, such as 3, 5, 7 or 9.

[0053] Optionally, in some embodiments, the value of n is negatively correlated with the number of first ribs j1.

[0054] It is understandable that the smaller the number of rows of openings 11 in the opening group 10, the less space it needs. Therefore, in the same space, the more first ribs j1 can be arranged, thereby improving the impact resistance of the support plate 100.

[0055] Optionally, n = 2 or 3, that is, the number of rows of openings 11 in the opening group 10 is 3 or 5.

[0056] The following text will take the example of n=2 in Figure 2, that is, a hole group 10 with 3 rows of holes 11, but it is not limited to this example.

[0057] Optionally, in some embodiments of this application, the bending region wz has a bending axis zz, and the number of opening groups 10 is 2m-1 rows, where m is a positive integer greater than 1. That is, the number of opening groups 10 is an odd number greater than 1, but it is not limited to this. For example, the number of opening groups 10 can also be an even number, such as 8, 10, 12 or 14.

[0058] In the top view of the support plate 100, the pattern of the bending area wz is a pattern symmetrically arranged about the bending axis zz, and the pattern of the m-th row of openings 10 is a pattern symmetrically arranged about the bending axis zz.

[0059] It should be noted that the pattern of the bending zone wz of the support plate 100 is the pattern of all the opening groups in the bending zone wz. The pattern of the bending zone wz of the support plate 100 is a symmetrical pattern to improve the uniformity of bending capacity and impact resistance. The m-th row of opening groups 10 is the central opening group 10 in the bending zone wz. The pattern of the m-th row of opening groups 10 is a symmetrical pattern about the bending axis zz. Combined with the setting of odd-numbered rows of opening groups 10, it not only facilitates the formation of a symmetrical pattern about the bending axis zz, but also allows the bending axis zz to correspond to the middle row of openings 11, which can minimize bending stress and improve the bending performance of the support plate 100.

[0060] Optionally, in some embodiments of this application, in at least a portion of the bending region wz, the distance Yp between any two adjacent rows of opening groups 10 in the first direction F1 is equal. That is, the opening groups 10 are arranged at the same distance Yp, for example, any two adjacent opening groups 10 are spaced apart by a distance of 0.25 mm.

[0061] Optionally, making the distance Yp between any two adjacent rows of openings 10 equal throughout the bending zone wz can better homogenize the impact resistance of the bending zone wz.

[0062] Optionally, in some embodiments of this application, in at least a portion of the bending region wz, the distance Yp between two adjacent rows of openings 10 decreases in the direction from the bending axis zz towards the non-bending region nw.

[0063] It is understandable that the distance Yp can be gradually changed in the entire bending zone wz or the middle area of ​​the bending zone wz. The area near the bending axis zz receives the greatest impact force, while the area further away from the bending axis zz receives less impact force. Therefore, the distance Yp between two adjacent rows of openings 10 is set to decrease from the bending axis zz towards the non-bending zone nw. This can specifically improve the impact resistance of the support plate 100. That is, a wider first rib j1 is set in the area with greater impact force, and a narrower first rib j1 is set in the area with less impact force. This can improve the bending capacity of the support plate 100 while meeting the impact resistance of each area.

[0064] Optionally, in some embodiments, in any group of openings 10, the distance Yc between two adjacent rows of openings 11 is equal. That is, in the first direction F1, the openings 11 are arranged according to the same distance Yx value, for example, any two adjacent openings 11 are spaced apart by a distance of 0.15 mm.

[0065] Optionally, in some embodiments of this application, the bending region wz includes a first opening region h1 and a second opening region h2 disposed on both sides of the first opening region h1, with the second opening region h2 disposed between the first opening region h1 and the non-bending region nw. The bending axis zz is located in the first opening region h1.

[0066] In the first opening area h1, in the first direction F1, the distance between two adjacent rows of opening groups 10 is greater than the distance between two adjacent rows of openings 11 in an opening group 10.

[0067] In the second opening area h2, in the first direction F1, the distance between two adjacent rows of opening groups 10 is equal to the distance between two adjacent rows of openings 11 in an opening group 10.

[0068] It is important to understand that the first opening area h1 is located near the bending axis zz, while the second opening area h2 is far from the bending axis zz. When the support plate 100 bends along the bending axis zz, the first opening area h1 experiences a larger impact force, while the second opening area h2 experiences a relatively smaller impact force. Therefore, a first rib j1 is specifically set between two adjacent rows of opening groups 10 in the first opening area h1, and a second rib j2 is set between two adjacent rows of opening groups 10 in the second opening area h2 to precisely improve the impact resistance of the support plate 100. Furthermore, the smaller width of the second rib j2 in the second opening area h2 can improve its bending capacity.

[0069] Additionally, it should be understood that in some embodiments, a first rib j1 may be provided between any two adjacent rows of opening groups 10 in the entire bending zone wz, or a first rib j1 and / or a second rib j2 may be provided between adjacent rows of opening groups 10 depending on the region of different impact forces received by the bending zone wz.

[0070] Optionally, in some embodiments of this application, referring to FIG2, in a top view of the support plate 100, a plurality of openings 11 are arranged in rows along the first direction F1, and adjacent rows of openings 11 partially overlap each other. The length direction of the openings 11 is the second direction F2. The plurality of openings 11 are arranged in rows (columns) along the second direction F2.

[0071] The holes 11 in two adjacent rows partially overlap each other, which allows for more holes 11 to be set in a limited space, thereby improving the bending capacity of the support plate 100.

[0072] In some embodiments of this application, in a top view of the support plate 100, the support plate 100 has a first side 12a and a second side 12b disposed opposite to each other, both the first side 12a and the second side 12b being perpendicular to the extension direction of the bending axis zz. In the second direction F2, a first row of openings 11 penetrates the first side 12a, and a last row of openings 11 penetrates the second side 12b. The distance x between two adjacent openings 11 in the second direction F2 is greater than the distance Yp between two adjacent rows of opening groups 10 in the first direction F1.

[0073] Using openings 11 to penetrate the first side 12a and the second side 12b can further improve the bending capacity of the support plate 100, but at the same time its impact resistance is relatively weakened. Therefore, the spacing x is set to be greater than the distance Yp to compensate for the impact resistance and avoid severe deformation in the bending area wz of the support plate 100 during bending.

[0074] In some embodiments of this application, in the first opening region h1, the lengths of the openings 11 in the same row are equal. In the second opening region h2, the lengths of the openings 11 in the same row decrease in the direction from the first opening region h1 toward the non-bending region nw.

[0075] Secondly, since the lengths of the openings 11 in the same row decrease in the second opening region h2, and there is an overlap length d between adjacent rows of openings 11 in the first direction F1, the overlap length of adjacent rows of openings 11 in the second opening region h2 also decreases in the direction from the first opening region h1 to the non-bending region nw. Furthermore, the overlap length d of adjacent rows of openings 11 in the first opening region h1 is the same.

[0076] Optionally, in the second direction F2, the first row of openings 11 located in the second opening area h2 is shortened towards the first side 12a, and the last row of openings 11 located in the second opening area h2 is shortened towards the second side 12b. The other rows of openings 11 located between the first and last rows are shortened from both ends of the openings 11 towards the middle.

[0077] Understandably, since the bending axis zz corresponds to the first opening area h1, the bending stress in the first opening area h1 is relatively large. Therefore, setting a longer opening 11 in the first opening area h1 can better release the bending stress and thus improve the bending capacity of the support plate 100, and improve the impact resistance through the first rib j1. The second opening area h2 is far away from the bending axis zz, and the side of the second opening area h2 that is far away from the first opening area h1 is the non-opening area h3. The rigidity of the non-opening area h3 is much stronger than that of the first opening area h1. Therefore, setting a gradually decreasing length opening 11 in the second opening area h2 can make the rigidity and stress transition smoothly.

[0078] In addition, in the second opening area h2, the rigidity of the second opening area h2 is greater than that of the first opening area h1 because the size of the opening 11 is shortened. Therefore, the second opening area h2 does not need to be provided with the first rib j1, which can achieve the effect of improving impact resistance.

[0079] Secondly, it is understandable that the non-aperture area h3 can be located in the bending area wz, but it is not limited to this. For example, it can also be located in the non-bending area nw, or the non-aperture area h3 can be located in the bending area wz and the non-bending area nw.

[0080] Optionally, the number of opening groups 10 located in the second opening area h2 is less than the number of opening groups 10 located in the first opening area h1, so as to set more first ribs j1.

[0081] Optionally, in some embodiments of this application, the pattern of each opening group 10 located in the first opening area h1 is an axisymmetric pattern, which facilitates the arrangement of the opening groups 10.

[0082] Optionally, in some embodiments of this application, in the top view of the support plate 100, in the first direction F1, the width w of the opening 11 is between 0.08 mm and 0.2 mm, for example, it can be 0.08 mm, 0.09 mm, 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm or 0.2 mm.

[0083] The two ends of the opening 11 are semi-circular, and the radius R of the semi-circle is half the width w of the opening 11.

[0084] In the second direction F2, the spacing x between two adjacent openings 11 is between 0.2 mm and 0.4 mm, for example, it can be 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.3 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm or 0.4 mm.

[0085] The length L of the opening 11 is between 4 mm and 9 mm, for example, it can be 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, 5.2 mm, 5.5 mm, 5.8 mm, 6 mm, 6.2 mm, 6.5 mm, 6.8 mm, 7 mm, 7.2 mm, 7.5 mm, 7.8 mm, 8 mm, 8.2 mm, 8.5 mm, 8.8 mm or 9 mm.

[0086] It is understandable that the bending capacity and impact resistance of the support plate 100 can be adjusted by adjusting the length L, width w, spacing X, and radius R of the opening 11, combined with the distances Yp and Yc. Furthermore, because the width (distance Yc) of the second rib j2 is relatively small, the opening group 10 has weak impact resistance and is prone to deformation. Therefore, it is necessary to set the spacing x to be greater than the distance Yp to improve the impact resistance of the opening group 10. However, if the spacing x is too large, it will affect the bending capacity. Therefore, the embodiments of this application select the range of values ​​of the above parameters to improve the impact resistance of the bending area wx while satisfying the bending capacity of the bending area wz of the support plate 100.

[0087] Optionally, Figure 3 shows a schematic diagram of the support plate 100 being bent in a teardrop shape. According to Figure 3, the bending area wz includes an inner bending area z1, a transition area z2, and an outer bending area z3 connected in sequence. The outer bending area z3 is connected to the non-bending area nw, and the first opening area h1 and the second opening area h2 are located in the inner bending area z1.

[0088] Among them, the inner bending zone z1 is a local area close to the transition zone z2, the outer bending zone z3 and the transition zone z2 are non-opening zones h3.

[0089] It is understandable that, for the teardrop-shaped bending area wz, the inner bending area z1 is the area subjected to the greatest impact force and bending stress. Therefore, the first opening area h1 and the second opening area h2 are set in the inner bending area z1 to coordinate the bending capacity and impact resistance of the support plate 100.

[0090] Please refer to Figures 4 and 5. Figures 4 and 5 are bending stress distribution cloud diagrams based on the teardrop-shaped bend of the support plate 100. As can be seen from Figures 4 and 5, after the adjustment of the first rib j1, the stress on the bending area wz of the support plate 100 is not high. The bending area wz of the support plate 100 can not only meet the bending capacity requirements, but also improve the impact resistance of the bending area wz.

[0091] Referring to Figure 6, correspondingly, this application embodiment also provides a display module 1000, which includes a flexible display panel 200 and a support plate 100 as described in any of the above embodiments, wherein the flexible display panel 200 is disposed on the support plate 100.

[0092] It should be noted that the structure of the support plate 100 of the display module 1000 in this application embodiment is similar to or the same as the structure of the support plate 100 described in any of the above embodiments, so it will not be described again here.

[0093] Optionally, the flexible display panel 200 can be an electroluminescent panel, such as an organic light-emitting display panel, a quantum dot light-emitting display panel, or a light-emitting diode display panel.

[0094] The support plate 100 of the display module 1000 in this embodiment includes multiple rows of openings disposed in the bending region wz.
