DETAILED DESCRIPTION

[0050] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0051] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0052] The technical solution of the embodiment of the present invention is to solve the above technical problems, and the overall idea is as follows:

[0053] Example 1

[0054] Reference Figure 1 , a support plate for supporting a flexible display panel provided by an embodiment of the present invention comprises a first area 1, a second area 2 located at least on one side of the first area 1, and a third area 4 located between the first area 1 and the second area 2; the first area 1 corresponds to at least the bending area of ​​the flexible display panel, a plurality of first opening groups 3 are arranged in the first area 1 along a first direction a, the first opening group 3 comprises a plurality of first openings 31 spaced along a second direction b, and a radial section of the first opening 31 extends along the second direction b; the second area 2 corresponds to a non-bending area of ​​the flexible display panel; at least one group of second opening groups 5 are arranged in the third area 4 along the first direction a, the second opening group 5 comprises a plurality of second openings 51 spaced along the second direction b, and at least a non-zero angle is formed between the radial section of the second opening 51 in the last group of the second opening groups 5 along the first direction a and the radial section of the first opening 31;

[0055] The first direction a is a direction from the first area 1 to the second area 2, and the second direction b is perpendicular to the first direction a.

[0056] Specifically, in order to solve the problem of uneven visual traces generated at the junction of the bending zone and the non-bending zone of the flexible display screen in the prior art, the support plate provided in the present embodiment is provided with a plurality of first opening groups 3 on the first area 1, and the first openings 31 spaced along the second direction b are used to improve the bendability of the first area 1 around the second direction b. Correspondingly, a third area 4 is provided between the first area 1 and the second area 2, and at least one group of second opening groups 5 is provided on the third area 4. The design of the second opening 51 and the first opening 31 forming a non-zero angle reduces the opening size and opening area of ​​the third area 4 along the second direction b, so that the third area 4 serves as a transition zone between the first area 1 and the second area 2, and the span of the opening size from the first area 1 to the second area 2 is reduced. For the case where the supporting force step difference of the flexible display panel is large, a transition is performed, and the falling tendency of the flexible display panel in the second direction b is reduced, thereby reducing or even eliminating the step difference, i.e., the uneven visual traces, of the flexible display panel at the junction of the first area 1 and the second area 2.

[0057] Among them, the flexible display panel is a display device that can be bent, folded, and curled, which can be used in mobile phones, tablet computers, wearable devices, car displays, smart homes, billboards, signs, signs and other electronic devices. The flexible display panel has a bending area and a non-bending area. The bending area is an area that can be bent. The non-bending area of ​​the flexible display panel can be bent, folded, and curled using the bendability of the bending area. The support plate provided in this embodiment can be set on the back of the flexible display panel to support it, thereby improving the strength and rigidity of the flexible display panel. This setting can be easily understood by those skilled in the art and will not be repeated here.

[0058] The support plate is a rigid plate with a small thickness, which can be but not limited to a steel plate, a resin plate, a carbon fiber plate, etc. The specific thickness can be designed and adjusted according to actual needs. The first area 1 and the second area 2 on the support plate correspond to the bending area and the non-bending area of ​​the flexible display panel respectively. The second area 2 can be located on one side of the first area 1 or on both sides of the first area 1. For example, the two second areas 2 can be symmetrical relative to the first area 1. Of course, they can also be Figure 1The two second regions 2 shown are of different sizes and can be adjusted according to the design of the actual product. In this embodiment, a plurality of first opening groups 3 are evenly spaced along the first direction a on the first region 1, and the first opening group 3 includes a plurality of first openings 31 evenly spaced along the second direction b, that is, in this embodiment, the support plate or the flexible display panel can be bent around the second direction b, and the second direction b can be the length direction or the width direction of the flexible display panel, and correspondingly, the first direction a is a direction perpendicular to the second direction b; the radial section of the first opening 31 extends along the second direction b, that is, the first opening 31 is a long strip hole extending along the second direction b, which can be a runway circle, a rectangular opening, etc. In this embodiment, the first region 1 may correspond only to the bending zone or to the bending zone and the weight-reducing zone at the same time. For example, a portion of the openings in the first region 1 along the first direction a are used to correspond to the bending zone to improve the bendability, and another portion of the openings in the first region 1 along the first direction a may not correspond to the bending zone but may be used to reduce the weight of the overall support plate and even the flexible display screen. It is not difficult to understand that a portion and another portion of the aforementioned first region 1 may be arranged in sequence along the first direction a, or may be a portion with weight-reducing holes on both sides of a portion. The second region b corresponds to the non-bending zone, and there are no openings in the second region 2, and there is no complete plate surface. The third region 4 may be as follows along the first direction a. Figure 2 A second opening group 5 is provided as shown, or Figure 3 As shown, a plurality of groups of second opening groups 5 are provided at intervals along the first direction a, as long as the radial cross-section of the second openings 51 in the last group or the last few groups of the second opening groups 5 along the first direction a forms a non-zero angle with the radial cross-section of the first opening 31, it is not difficult to understand that the second opening 51 can also be a long hole, but the extension direction of its length direction needs to be different from the extension direction of the first opening 31, and the angle between the two can be between 0-180 degrees and does not include 0 and 180, for example: the angle between the two is 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, The third area 4 is a transition area between the first area 1 and the second area 2, and the size of the opening along the second direction b is reduced at the junction of the third area 4 and the second area 2. The support strength of the flexible display panel at this position is greater than that of the first area 1 and slightly smaller than that of the second area 2. The falling area of ​​the flexible display panel in the opening at this position is significantly reduced, effectively reducing the support step difference at the junction of the first area 1 and the second area 2, thereby reducing or even eliminating the uneven visual traces. Of course, the extension directions of several second openings 51 in the same second opening group 5 can be the same or different, for example: Figure 4 and Figure 5 tilted in the same direction as shown, and Figure 6The non-co-directional tilt shown. In this embodiment, when a plurality of second opening groups 5 are provided at intervals along the first direction a, the opening density on the third region 4 can be gradually reduced to increase the supporting area and supporting force for the flexible display panel, and further improve the transition effect of the third region 4 as a transition zone, for example: the first, the spacing between adjacent second opening groups 5 in the first direction a gradually increases; the second, the spacing between adjacent second openings 51 in the second opening group 5 in the first direction a gradually increases; the third, the size of the second opening 51 in the first direction a in the second direction b gradually decreases; the first, second and third settings mentioned above can be used alone, or in any combination of two, or in combination of all three at the same time.

[0059] According to the above, the support plate provided by the present application, by setting the second opening 51 in the second opening group 5 closest to the second area 2 in the third area 4 serving as the transition zone to have a non-zero angle with the first opening 31, effectively reduces the size of the opening in the second direction b at the junction with the second area 2, eliminates the large difference in support strength between the second area 2 and the first area 1 and the tendency of the flexible display panel to fall along the second direction b, thereby reducing or even eliminating the phenomenon of the flexible display panel having a step difference, i.e., an uneven visual trace at the junction of the first area 1 and the second area 2; thereby solving the problem of the flexible display screen in the prior art producing uneven visual traces at the junction of the bending area and the non-bending area.

[0060] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0061] Further, see Attachment Figure 3 In the support plate provided in this embodiment, in a specific implementation, the radial cross-section of the second openings 51 in the last group of the second opening group 5 along the first direction a is perpendicular to the radial cross-section of the first opening 31 .

[0062] It can be understood that in order to minimize the number of openings along the second direction b at the junction of the third area 4 and the second area, in this embodiment, the radial cross-section of the second opening 51 located in this area is set to be perpendicular to the radial cross-section of the first opening 31, that is, the second opening 51 is a long hole extending along the first direction a, and thus the opening size of the second opening 51 in the second direction b is smaller than the opening size of the second opening 51 in the second direction b at any other angle.

[0063] Further, see Attachment Figure 3In the support plate provided in this embodiment, in a specific implementation, the angle between the radial cross section of the second opening 51 and the radial cross section of the first opening 31 in the first direction a gradually increases.

[0064] It can be understood that in order to improve the transition effect of the third region 4 as a transition zone, in this embodiment, the plurality of second opening groups 5 spaced along the first direction a in the third region 4 are arranged so that the angle between the radial cross section of the second opening 51 and the radial cross section of the first opening 31 in the first direction a gradually increases, that is, the closer the radial cross section of the second opening 51 is to the second region 2 in the first direction a, the larger the angle between the radial cross section of the first opening 31 is. For example: Figure 6 , the third region 4 includes six groups of second opening groups 5. For example, the radial cross section of the first opening 31 in the last group of first opening groups 3 in the first region 1 is 0 degrees, and the radial cross sections of the second openings 51 in the six groups of second opening groups 5 can be 10 degrees, 20 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degrees relative to the radial cross section of the first opening 31, so as to gradually reduce the size of the opening in the second direction b at the junction of the third region 4 and the second region 2, and achieve a sufficient transition. Of course, it is not difficult to understand that the content described here can be combined with the content described above.

[0065] Further, see Attachment Figure 6 In the support plate provided in this embodiment, in a specific implementation, the second opening group 5 includes a plurality of sub-opening groups 52 spaced along the second direction b; the sub-opening group 52 includes two second openings 51, and the two second openings 51 are symmetrical relative to the first straight line; wherein the first straight line is parallel to the first direction a.

[0066] It can be understood that in order to improve the force uniformity of the support plate when the flexible display panel is bent, in this embodiment, the second opening group 5 is configured to include a plurality of sub-opening groups 52 spaced along the second direction b, and each sub-opening group 52 includes two second openings 51 symmetrical with respect to the first straight line, so that each sub-opening group 52 is arranged uniformly in the second direction b, and the force during the bending is also uniform. The two second openings 51 in each sub-opening group 52 can be Figure 6 The ones shown as being far away from each other along the first direction a may also be close to each other along the first direction a. Of course, it is not difficult to understand that the content described here can be combined with the content described above.

[0067] Further, see Attachment Figure 7 In the support plate provided in this embodiment, in a specific implementation, the second openings 51 in adjacent second opening groups 5 are arranged alternately along the second direction b.

[0068] It can be understood that, in order to improve the transition effect of the third region 4, the second openings 51 in adjacent second opening groups 5 in this embodiment are arranged in a staggered manner along the second direction b, that is, Figure 7 As shown, taking the second opening groups 5 of the first, second and third groups as an example, the second openings 51 of the second group are translated a certain distance in the opposite direction of the second direction b relative to the second openings 51 of the first group, and the second openings 51 of the third group are translated a certain distance in the second direction b relative to the second openings 51 of the second group. The translation distance or the staggered distance in the second direction b can be designed and adjusted according to actual needs, so that the position distribution of the unopened holes on the third area 4 is more uniform and more comprehensive, rather than a row or a column of unopened holes in a certain direction, so as to improve the uniformity and comprehensiveness of the support of the third area 4 for the flexible display panel, and play a role in gradually eliminating visual traces. Of course, the second openings 51 of the first group can also be translated a certain distance in the second direction b or the opposite direction of the second direction b relative to the first openings 31 of the previous group.

[0069] Further, see Attachment Figure 8 In the support plate provided in this embodiment, in a specific implementation, a fourth area 6 is provided between the first area 1 and the third area 4; a plurality of third opening groups 7 are provided on the fourth area 6 along the first direction a, and the third opening group 7 includes a plurality of third openings 71 spaced along the second direction b; the distance between adjacent third opening groups 7 is greater than the distance between adjacent first opening groups 3; the radial cross section of the third opening 71 is parallel to the radial cross section of the first opening 31, and the size of the third opening 71 along the second direction b is smaller than the size of the first opening 31 along the second direction b.

[0070] It can be understood that in order to improve the gradual transition effect of the transition zone, in this embodiment, a fourth area 6 is set between the first area 1 and the third area 4, and a plurality of third opening groups 7 are arranged at intervals along the first direction a in the fourth area 6, and third openings 71 are arranged at intervals along the second direction b in the third opening group 7. In this embodiment, the radial cross-section of the third opening 71 is set to be parallel to the radial cross-section of the first opening 31, and the distance between adjacent third opening groups 7 is set to be greater than the distance between adjacent first opening groups 3, and the size of the third opening 71 along the second direction b is set to be smaller than the size of the first opening 31 along the second direction b, so that the opening density and opening size on the fourth area 6 are smaller than the settings of the first area 1, thereby increasing the support area and support force. It is not difficult to understand that the size of the second opening 51 on the third area 4, especially the size along the second direction b, can be less than or equal to the third opening 71 in the last group of third opening groups 7 in the fourth area 6, the spacing between adjacent second opening groups 5 in the third area 4 can be less than or equal to the spacing between adjacent third opening groups 7 in the fourth area 6, and the spacing of the second openings 51 in the third area 4 to the same second opening group 5 can be less than or equal to the spacing between adjacent third openings 71 in the same third opening group 7 in the fourth area 6.

[0071] Further, see Attachment Figure 8 In the support plate provided in this embodiment, in a specific implementation, the distance between the plurality of the third opening groups 7 in the first direction a gradually increases; and / or the size of the third openings 71 in the first direction a gradually decreases along the second direction b; and / or the spacing between adjacent third openings 71 in the third opening group 7 in the first direction a gradually increases.

[0072] It can be understood that in order to gradually increase the support area and support force of the transition zone, smoothly transition and eliminate visual folds, at least the following three methods can be adopted in this embodiment, for example, the first method is to gradually increase the distance between the plurality of third opening groups 7 in the first direction a; the second method is to gradually reduce the size of the third openings 71 in the first direction a along the second direction b; the third method is to gradually increase the spacing between adjacent third openings 71 in the third opening group 7 in the first direction a. It is also not difficult to understand that the first, second and third setting methods can be used alone, or in any combination of two or more, or in combination of all three at the same time.

[0073] Further, see Attachment Figure 8In the support plate provided in this embodiment, in a specific implementation, the distance between adjacent second opening groups 5 is greater than the distance between adjacent third opening groups 7; and / or the size of the second opening 51 along the second direction b is smaller than the size of the third opening 71 along the second direction b; and / or the spacing between adjacent second openings 51 in the second opening group 5 is greater than the spacing between adjacent third openings 71 in the third opening group 7.

[0074] It can be understood that in order to gradually increase the support area and support force of the transition zone, smoothly transition and eliminate visual folds, the third area 3 and the fourth area 6 in this embodiment can be set in at least the following three ways, for example, the first way is that the distance between adjacent second opening groups 5 is greater than the distance between adjacent third opening groups 7; the second way is that the size of the second opening 51 along the second direction b is smaller than the size of the third opening 71 along the second direction b; the third way is that the spacing between adjacent second openings 51 in the second opening group 5 is greater than the spacing between adjacent third openings 71 in the third opening group 7. It is also not difficult to understand that the first, second and third setting methods mentioned above can be used alone, or in any combination of two, or in combination of all three at the same time.

[0075] Example 2

[0076] The present embodiment provides a flexible display screen, which includes a flexible display panel and a support plate, wherein the flexible display panel includes a bending area and a non-bending area located at least on one side of the bending area; the support plate includes a first area 1 and a second area 2 located at least on one side of the first area 1; the first area 1 corresponds to at least the bending area, and a plurality of first opening groups 3 are arranged in the first area 1 along a first direction a, the first opening group 3 includes a plurality of first openings 31 spaced along a second direction b, and a radial cross section of the first opening 31 extends along the second direction b; the second area 2 corresponds to the non-bending area; a third area 4 is arranged between the first area 1 and the second area 2, and at least one group of second opening groups 5 are arranged in the third area 4 along the first direction a, the second opening group 5 includes a plurality of second openings 51 spaced along the second direction b, and a non-zero angle is formed between the radial cross section of the second opening 51 in the last group of the second opening groups 5 along the first direction a and the radial cross section of the first opening 31; wherein the first direction a is the direction from the first area 1 to the second area 2, and the second direction b is perpendicular to the first direction a.

[0077] It can be understood that the support plate in this embodiment is the support plate described in the embodiment, and its structure and working principle can refer to the detailed description of Example 1, and no further details will be given here; by setting the second opening 51 in the second opening group 5 closest to the second area 2 on the third area 4 on the support plate as the transition zone to have a non-zero angle with the first opening 31, the size of the opening in the second direction b is effectively reduced at the junction with the second area 2, eliminating the large difference in support strength between the second area 2 and the first area 1 and the tendency of the flexible display panel to fall along the second direction b, thereby reducing or even eliminating the phenomenon of the step difference, i.e., the uneven visual traces, of the flexible display panel at the junction of the first area 1 and the second area 2; thereby solving the problem of uneven visual traces generated by the flexible display screen at the junction of the bending area and the non-bending area in the prior art.
