Detailed Description
The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.
With the development of the bendable screen technology, the flexibility of the bendable screen can greatly improve the application diversity of the display module, and the bendable screen is popular with users, and the flexible bending screen is gradually applied to personal terminals in a large number (such as foldable mobile phones, curled-screen mobile phones and the like). However, the flexible screen is generally lower in rigidity, and in order to achieve better support for the flexible screen, a support member is generally attached to the bottom surface of the flexible screen, so that the flexible screen can be unfolded and arranged flatly.
In order to avoid affecting the bending performance of the flexible screen after the support member is added, and when the flexible screen is applied to a display module, not every area needs to be bent, only a fixed partial area (bending area) needs to be bent usually, and other areas (non-bending areas) do not need to be bent, namely, the flexible screen is provided with the bending area and the non-bending area. Therefore, the support piece can be correspondingly arranged to comprise a bending part and a non-bending part, the bending part is arranged corresponding to the bending area of the flexible screen, and the non-bending part is arranged corresponding to the non-bending area of the flexible screen. However, the bending stiffness of the bent portion of the support is generally small, while the bending stiffness of the non-bent portion is generally large, so that the stress variation at the boundary between the bent portion and the non-bent portion is severe, i.e., the absolute value of the difference between the bending stiffness of the two is large. And including the optics glue film in the flexible screen, because its stress variation is violent, consequently the optics glue film can carry out irreversible pile up in its boundary department, leads to the flexible screen to appear comparatively obvious crease and dark line after buckling many times, has reduced display module's outward appearance and display performance.
In view of the above, in order to solve the above problems, the present embodiment provides a display module. Referring to fig. 1-2, fig. 1 is a top view of a display module according to an embodiment of the present disclosure. Fig. 2 is a schematic sectional view taken along a-a in fig. 1. This embodiment provides a display module assembly 1, specifically, display module assembly 1 includes: a flexible screen 20 and a support 10, the flexible screen 20 having a bending region 21 and a non-bending region 22 connected. The support member 10 is connected to the flexible screen 20, the support member 10 includes a bending portion 11, a transition portion 12 and a non-bending portion 13, the transition portion 12 is connected between the bending portion 11 and the non-bending portion 13, the bending portion 11 and the transition portion 12 correspond to the bending area 21, the non-bending portion 13 corresponds to the non-bending area 22, and the bending rigidity of the transition portion 12 close to the bending portion 11 is smaller than the bending rigidity of the transition portion 12 close to the non-bending portion 13.
The display module 1 provided by the present embodiment includes a flexible screen 20, and the flexible screen 20 has a bending region 21 and a non-bending region 22 connected to each other. The flexible screen 20 can be bent everywhere, and the bending area 21 and the non-bending area 22 mean that the flexible screen 20 only needs to be bent in the bending area 21 in the actual use process of the flexible screen 20, and the flexible screen 20 in the non-bending area 22 does not need to be bent. The number and positional relationship between the bending regions 21 and the non-bending regions 22 are not limited in this embodiment. For example, the number of the bending regions 21 and the number of the non-bending regions 22 may be multiple, and when the number of the bending regions 21 is multiple, one non-bending region 22 is connected between each bending region 21, and it can also be understood that the flexible screen 20 has multiple bending regions 21. In the present embodiment, the number of the bending regions 21 is only one, the number of the non-bending regions 22 is two, and the non-bending regions 22 are connected to two opposite sides of the bending regions 21.
The display module 1 provided in this embodiment further includes a support 10, and the support 10 can function as a support for the flexible screen 20 as described in the related art. Optionally, the material of the supporting member 10 includes a hard material such as metal, alloy or polymer. The support 10 is added with a transition portion 12 in the present embodiment in addition to the bent portion 11 and the non-bent portion 13 in the related art. Here, the transition portion 12 and the bent portion 11 both correspond to the bending region 21, which means that the transition portion 12 does not affect the bending of the flexible panel 20, but the bending stiffness of the transition portion 12 is between the bent portion 11 and the non-bent portion 13. In other words, the bending stiffness of the transition portion 12 is greater than that of the bent portion 11, and the bending stiffness of the transition portion 12 is less than that of the non-bent portion 13. Here, it should be noted that the bending stiffness, i.e., the bending stiffness of the cross section, is the bending moment required to be applied to the cross section per unit corner, and it shows the capability of the cross section to resist bending deformation, i.e., the larger the bending stiffness, the less the bending stiffness means the more the portion is easily bent. In this way, the transition portion 12 can be used to relieve the stress variation between the bending portion 11 and the non-bending portion 13, so that the stress variation is gentle, and the crease and the dark line caused by bending the flexible screen 20 are relieved.
In addition, in the present embodiment, the bending stiffness of the transition portion 12 near the bent portion 11 is smaller than the bending stiffness of the transition portion 12 near the non-bent portion 13, so that the amount of change in the bending stiffness from the bent portion 11 to the transition portion 12 to the non-bent portion 13 is reduced, even if the stress is gradually changed from the bent portion 11 to the non-bent portion 13, and no abrupt change occurs. It can also be understood that the magnitude of the absolute value of the difference between the bending stiffness of the end of the transition portion 12 close to the non-bent portion 13 and the bending stiffness of the end of the non-bent portion 13 close to the transition portion 12 is reduced by the special arrangement of the transition portion 12. Therefore, the crease and the hidden line generated by bending at the junction of the transition part 12 and the non-bending part 13 of the flexible screen 20 can be relieved, the expressive force of the terminal product of the flexible screen 20 is greatly improved, and the display performance of the display module 1 is improved.
Alternatively, the present embodiment may also gradually increase the bending rigidity of the transition portion 12 from the direction near the bent portion 11 to the direction near the non-bent portion 13 (as shown in the direction D1 in fig. 2), thereby gradually changing the stress. It can also be understood that in the present embodiment, in the direction from the bent portion 11 to the non-bent portion 13, the stress of the flexible screen 20 is gradually increased from the size of the bent portion 11 to the size of the non-bent portion 13, so that the stress change at each position is controlled within the receiving range, thereby further alleviating the crease and dark line generated by bending the flexible screen 20, and further improving the display performance of the display module 1.
Optionally, the bending stiffness of the non-bent portion 13 is 1-5 times the bending stiffness of the end of the transition portion 12 near the non-bent portion 13. As described above, the present embodiment can control the bending stiffness of the transition portion 12 near the bending portion 11 to be smaller than the bending stiffness of the transition portion 12 near the non-bending portion 13, so as to reduce the variation range of the stress at the boundary between the transition portion 12 and the non-bending portion 13, and specifically, the present embodiment can increase the bending stiffness of the transition portion 12 near the non-bending portion 13 to satisfy the requirement that the bending stiffness of the non-bending portion 13 is 1-5 times of the bending stiffness of the transition portion 12 near the non-bending portion 13, so as to greatly reduce the stress variation range at the boundary between the transition portion 12 and the non-bending portion 13, and further alleviate the occurrence of the crease and the dark line.
Optionally, the bending stiffness of the bent portion 11 is less than or equal to the bending stiffness of the end of the transition portion 12 close to the bent portion 11. The above description describes the relationship between the transition portion 12 and the non-bent portion 13, and as for the relationship between the transition portion 12 and the bent portion 11, the present embodiment can make the bending stiffness of the bent portion 11 less than or equal to the bending stiffness of the end of the transition portion 12 close to the bent portion 11. This achieves a tendency of gradually increasing bending stiffness from the bent portion 11 to the transition portion 12 and then to the non-bent portion 13 of the support member 10 as a whole, thereby making the change of stress more gradual and further alleviating the occurrence of dark marks and folding lines of the flexible screen 20.
Referring to fig. 3, fig. 3 is a top view of a display module according to another embodiment of the present disclosure. In the present embodiment, the transition portion 12 includes a plurality of sub-transition portions 120 connected to each other, and the bending stiffness of the sub-transition portion 120 near the bending portion 11 is smaller than that of the sub-transition portion 120 near the non-bending portion 13.
In order to achieve the content of the above embodiments, the present embodiment provides a specific implementation manner, the transition portion 12 can be divided into a plurality of sub-transition portions 120 connected to each other, and then only the bending stiffness of each sub-transition portion 120 needs to be controlled, for example, the bending stiffness of the sub-transition portion 120 near the bending portion 11 is smaller than that of the sub-transition portion 120 near the non-bending portion 13, so that the bending stiffness of the transition portion 12 near the bending portion 11 is smaller than that of the transition portion 12 near the non-bending portion 13, thereby achieving the precise control of the bending stiffness of the transition portion 12.
Please refer to fig. 4, fig. 4 is a top view of a display module according to another embodiment of the present application. In this embodiment, the sub-transition portion 120 is provided with a blind hole 121 and exposes the flexible screen 20, and the size of the blind hole 121 close to the bending portion 11 is larger than the size of the blind hole 121 close to the non-bending portion 13.
In order to precisely control the bending stiffness of each sub-transition 120, the present embodiment provides a specific implementation, for example, the bending stiffness of the sub-transition 120 can be controlled by opening the blind hole 121 on the sub-transition 120. The blind hole 121 penetrates through a side surface of the sub-transition portion 120 facing away from the flexible screen 20 and a side surface of the sub-transition portion 120 close to the flexible screen 20, so that the flexible screen 20 is exposed from the blind hole 121. In this embodiment, the size of the blind hole 121 near the bending portion 11 can be made larger than the size of the blind hole 121 near the non-bending portion 13. This is because the size of the blind hole 121 may directly affect the bending stiffness of the sub-transition 120. The larger the size of the blind hole 121, the smaller the area of the sub-transition 120 remaining in cross section at the blind hole 121, and thus the less bending stiffness. Vice versa, the smaller the size of the blind hole 121, the larger the area left by the cross section of the sub-transition 120 at the blind hole 121, and thus the greater the bending stiffness. The bending stiffness can be precisely controlled by making the size of the blind hole 121 on the sub-transition portion 120 close to the bending portion 11 larger than the size of the blind hole 121 on the sub-transition portion 120 close to the non-bending portion 13.
Alternatively, each blind hole 121 may be prepared by masking and wet etching. For example, a complete support member 10 is provided, and a barrier layer is formed on the surface of the support member 10. Then, the position and the size of each blind hole 121 are designed on the mask plate through the mask plate, the blocking layer corresponding to the position of the blind hole 121 of the mask plate is removed, and the supporting member 10 is exposed. Then, the mask is removed, and the supporting member 10 is etched by using an acid solution, so that the required blind holes 121 are correspondingly formed on the supporting member 10.
Please refer to fig. 5, fig. 5 is a top view of a display module according to another embodiment of the present application. In this embodiment, in the direction from the bent portion 11 to the non-bent portion 13, the size of the blind hole 121 on the 2N-1 th sub-transition portion 120 is larger than the size of the blind hole 121 on the 2N +1 th sub-transition portion 120; wherein N is a positive integer.
The above description describes the relationship between the bending stiffness at the two ends of the transition section 12, and the present application describes several specific implementations as to the magnitude of the bending stiffness in other regions of the transition section 12. In the first way, the size of the blind hole 121 on the 2N-1 th sub-transition portion 120 may be larger than the size of the blind hole 121 on the 2N +1 th sub-transition portion 120 in the direction from the bent portion 11 to the non-bent portion 13 (as shown in the direction of D2 in fig. 5). Since the number of the sub-transition portions 120 is plural, the size of the blind holes 121 on odd number of sub-transition portions 120 can be regulated to a certain rule, that is, the size of the blind holes 121 on the 1 st, 3 rd, 5.. 2N +1 th sub-transition portions 120 is gradually reduced in the direction from the bending portion 11 to the non-bending portion 13, so that the bending rigidity of the transition portion 12 is gradually increased in the direction from the bending portion 11 to the non-bending portion 13.
Referring to fig. 5 again, in the present embodiment, in a direction from the bending portion 11 to the non-bending portion 13, a size of the blind via 121 on the 2 nth sub-transition portion 120 is larger than a size of the blind via 121 on the 2N +2 th sub-transition portion 120; wherein N is a positive integer.
In a second implementation manner, in a direction from the bent portion 11 to the non-bent portion 13, a size of the blind hole 121 on the 2 nth sub-transition portion 120 may be larger than a size of the blind hole 121 on the 2N +2 nd sub-transition portion 120. Different from the first implementation, the size of the blind holes 121 on even number of sub-transition portions 120 can be made to exhibit a certain rule, that is, the size of the blind holes 121 on the 2 nd, 4 th, 6 th.. 2N +2 th sub-transition portions 120 is gradually reduced in the direction from the bending portion 11 to the non-bending portion 13, so that the bending rigidity of the transition portion 12 is gradually increased in the direction from the bending portion 11 to the non-bending portion 13.
Referring to fig. 5 again, in the present embodiment, in a direction from the bending portion 11 to the non-bending portion 13, a size of the blind via 121 on the 2N-1 th sub-transition portion 120 is larger than a size of the blind via 121 on the 2N th sub-transition portion 120; wherein N is a positive integer.
In a third implementation manner, in a direction from the bent portion 11 to the non-bent portion 13, a size of the blind hole 121 on the 2N-1 th sub-transition portion 120 may be larger than a size of the blind hole 121 on the 2N nd sub-transition portion 120. It can also be understood that the size of the blind hole 121 on the sub-transition portion 120 gradually decreases in the direction from the bent portion 11 to the non-bent portion 13, that is, the size of the blind hole 121 on the 1 st, 2 nd, 3 rd, 4.. 2 nth sub-transition portion 120 gradually decreases, so that the bending stiffness of the transition portion 12 gradually increases in the direction from the bent portion 11 to the non-bent portion 13.
Optionally, in the present embodiment, the widths of the sub-transition parts 120 are equal in a direction parallel to the arrangement direction of the plurality of sub-transition parts 120. This embodiment may equalize the width of each sub-transition 120, thereby making the structure of the transition 12 simpler and allowing better control of the size of the blind hole 121. In addition, the direction parallel to the arrangement direction of the plurality of sub-transition portions 120 may also be understood as a bending direction of the flexible screen 20.
Further alternatively, in the present embodiment, the widths of the blind holes 121 are the same in the direction parallel to the arrangement direction of the plurality of sub-transition portions 120. The embodiment can also control the width of the blind hole 121 to be the same, so that the size change of the blind hole 121 can be controlled by only controlling the length of the blind hole 121. In the present embodiment, such a control method is adopted, and as is apparent from fig. 5, the length of the blind hole 121 becomes smaller in the direction from the bent portion 11 to the non-bent portion 13.
Please refer to fig. 6, fig. 6 is a top view of a display module according to another embodiment of the present application. In the present embodiment, the length of the bent portion 11 is smaller than the length of the transition portion 12 in the direction perpendicular to the arrangement direction of the plurality of sub-transition portions 120. It can also be understood that the length of the bent portion 11 is reduced, so that the transition portion 12 and the bent portion 11 form a groove, so that other components can be installed at the groove, thereby increasing the assembly space of the display module 1.
Referring to fig. 6 again, in the present embodiment, the blind via 121 includes a plurality of sub blind vias 1210 arranged at intervals, and in a direction from the bending portion 11 to the non-bending portion 13, the sub blind via 1210 portion on the 2N-1 th sub transition portion 120 corresponds to a gap between two adjacent sub blind vias 1210 on the 2N th sub transition portion 120; wherein N is a positive integer.
As can be seen from the above, each sub-transition portion 120 can be provided with a blind hole 121, and in the present embodiment, the blind hole 121 includes a plurality of sub-blind holes 1210 arranged at intervals, so that the blind holes 121 are provided on the sub-transition portions 120 as many as possible, thereby reducing the difficulty in providing the blind holes 121. In addition, in the present embodiment, in the direction from the bent portion 11 to the non-bent portion 13, the sub blind via 1210 portion on the 2N-1 th sub transition portion 120 may correspond to a gap between two adjacent sub blind vias 1210 on the 2N th sub transition portion 120. It can also be understood that, in two adjacent sub-transitions 120, the portion of the blind sub-hole 1210 in one sub-transition 120 is disposed opposite to the gap between the two blind sub-holes 1210 in the other sub-transition 120, that is, the blind sub-holes 1210 in two adjacent sub-transitions 120 are disposed in a staggered manner. Therefore, the difficulty in manufacturing the sub-blind holes 1210 can be reduced, and the gap between two sub-blind holes 1210 on two adjacent sub-transition parts 120 is prevented from being too small, so that the supporting piece 10 is easy to break.
Optionally, the length of the blind sub-hole 1210 is 0.2-20 mm. Further optionally, the length of the blind sub-hole 1210 is 2-6 mm.
Referring to fig. 7, fig. 7 is a top view of a display module according to another embodiment of the present disclosure. In the present embodiment, the bending rigidity of the bent portion 11 can be adjusted by opening the blind hole 121 in the bent portion 11. Alternatively, the blind holes 121 may be uniformly opened on the bent portion 11, so as to maintain the bending rigidity of the whole bent portion 11 to be uniform.
Please refer to fig. 8, fig. 8 is a top view of a display module according to another embodiment of the present application. In this embodiment, the blind hole 121 includes a plurality of sub blind holes 1210 arranged at intervals, the sub blind holes 1210 penetrate through a side surface of the supporting member 10 close to the flexible screen 20 and a side surface of the supporting member away from the flexible screen 20, and a part of the sub blind holes 1210 further penetrate through the peripheral side surface 14 of the supporting member 10.
As can be seen from the above, the opening of the blind hole 121 penetrates through the upper and lower surfaces of the supporting member 10, that is, the sub-blind hole 1210 penetrates through a side surface of the supporting member 10 close to the flexible screen 20 and a side surface thereof away from the flexible screen 20, so as to expose the flexible screen 20. In this embodiment, a part of the sub blind holes 1210 may further penetrate through the peripheral side surface 14 of the supporting member 10, that is, a part of the sub blind holes 1210 is opened at the end of the supporting member 10, so that the space of the sub transition portion 120 may be saved, and more sub blind holes 1210 are opened on the sub transition portion 120, thereby further reducing the difficulty of adjusting the bending stiffness of the transition portion 12.
Please refer to fig. 5 and 9 together, and fig. 9 is a top view of a display module according to another embodiment of the present application. In this embodiment, the blind hole 121 includes a plurality of sub blind holes 1210 disposed at intervals, a portion of the sub blind holes 1210 extends in a direction perpendicular to the arrangement direction of the plurality of sub transition portions 120, and a portion of the sub blind holes 1210 extends in a direction parallel to the arrangement direction of the plurality of sub transition portions 120.
As can be seen from the above, the size of the blind via 121 or the blind sub-via 1210 controls the bending stiffness of the sub-transition 120. And the length direction of the blind via 121 or the sub-blind via 1210 is a main extending direction, the controllable sub-blind via 1210 of the present embodiment extends along a direction perpendicular to the arrangement direction of the plurality of sub-transition portions 120 (as shown in fig. 5), or the present embodiment may further control a portion of the sub-blind via 1210 to extend along a direction perpendicular to the arrangement direction of the plurality of sub-transition portions 120, and a portion of the sub-blind via 1210 extends along a direction parallel to the arrangement direction of the plurality of sub-transition portions 120. This allows more blind sub-holes 1210 to be formed in the transition portion 12, thereby further reducing the difficulty of the transition portion 12 in controlling bending stiffness.
Alternatively, the shape of the blind sub-hole 1210 is not limited in this application, for example, as shown in fig. 9, the shape of the blind sub-hole 1210 is not limited to a rectangle or an oval.
Referring to fig. 10, fig. 10 is a schematic cross-sectional view of an electronic device according to an embodiment of the disclosure. This embodiment provides an electronic equipment 2, including casing 3, mainboard 4, battery 5 and like the display module assembly 1 that the above-mentioned embodiment of this application provided, display module assembly 1 locates on the casing 3, accommodating space has in the casing 3, mainboard 4 with battery 5 all locates in the accommodating space, mainboard 4 electricity is connected battery 5 with display module assembly 1.
