Detailed Description
In order to make the objects, technical solutions and effects of the present application clearer and more specific, the present application will be described in further detail below with reference to the accompanying drawings and examples. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1 and 2, fig. 1 is a schematic structural view of an embodiment of a screen support according to the present application, and fig. 2 is a schematic structural view of another view of an embodiment of a screen support according to the present application.
In the longitudinal direction (X direction in the drawing) of the screen support 1, the screen support 1 includes at least one bendable region a and non-bendable regions B disposed on both sides of the bendable region a in the X direction; wherein the flexibility of the screen support 1 in the non-bending region B is less than that in the bendable region a. Optionally, when the screen support 1 is suitable for a bending display module, the number of the bendable regions a may be one or a plurality of the bendable regions a arranged at intervals, and each of the bendable regions a may be provided with a bending center C. Subsequently, when the screen support 1 is attached to the flexible screen, the flexible screen is bendable in the bendable region a and the flexible screen is inflexible in the non-bendable region B. Alternatively, when the screen support 1 is suitable for a roll-up display module, the number of the bendable regions a may be one, and then when the screen support 1 is attached to the flexible screen, the flexible screen is windable at the bendable regions a.
Specifically, in the longitudinal direction (X direction in the drawing) of the screen support 1, the screen support 1 is provided with at least one first portion 11, each first portion 11 including a plurality of thinned sections 111 arranged side by side in the X direction and connected in sequence; wherein the average thickness of the plurality of thinned sections 111 in each first portion 11 decreases in sequence along the length direction and increases in sequence.
In the above design manner, the screen support 1 is not provided with an opening, and the flexibility of the screen support 1 is increased by gradually changing the thickness of the plurality of thinned sections 111; and when the screen support 1 is bent, the bending moment distribution born by the screen support 1 is decomposed by the plurality of thinning sections 111, so that the stress of a critical area between the non-bending area B and the bendable area A is reduced, the fracture phenomenon is avoided, the stress condition of the screen support is improved, and the failure load of the screen support is improved.
Optionally, at least one first portion 11 is provided in one bendable region a; the screen support 1 further comprises a second portion 12 arranged in correspondence of the non-bending zone B, the average thickness of the second portion 12 being greater than the average thickness of the thinned section 111 of the first portion 11, of which the average thickness is the greatest. The design mode can increase the flexibility of the screen support 1 in the bendable region A and ensure the rigidity of the non-bending region B.
Preferably, at least one first portion 11 located in the bendable region a may be disposed axisymmetrically about the bending center C. The design mode can enable the flexibility of the screen support piece 1 in the bendable region A to be arranged with the bending center C as axisymmetric, and the consistency of the bending degrees of the two sides of the bending center C is ensured when the flexible screen is bent.
And/or the thickness of the second portion 12 in the non-inflection region C is the same in the length direction. The rigidity of the screen support piece 1 in the non-bending area B can be symmetrically arranged by taking the bending center C as an axis, and the consistency of the flatness of the two sides of the bending center C of the flexible screen can be ensured.
Further, the thickness of the single thinned section 111 is kept uniform in the length direction. That is, the longitudinal section of the single thinned section 111 in the length direction Y is rectangular, the stress distribution is more uniform under the rectangular section, and the reliability of the screen support 1 is higher.
Optionally, referring to fig. 3, in some embodiments, rounded corners 14 are provided between adjacent thinned segments 111 and/or second portions 12 and adjacent thinned segments 111 to reduce stress concentrations at the steps.
Of course, in other embodiments, the structural design of the single thinned section 111 may be other. For example, referring to fig. 4 and 5, in the length direction, the thickness of the single thinned section 111 gradually decreases in the direction in which the average thickness of the plurality of thinned sections 111 decreases. The thickness of the single thinning section 111 can be gradually thinned towards the bending center C, namely, the thickness of one side close to the non-bending area is larger than that of one side close to the bending area, and meanwhile, the bending performance and the flatness of the screen body are ensured; the longitudinal section of the thinned section 111 along the X-direction may be trapezoidal, and further, the longitudinal section is isosceles trapezoid, so that gradual change of moment of inertia is ensured, and excessive concentration of stress is avoided.
Alternatively, the one of any two adjacent thinned segments 111 having the greater average thickness has the smallest thickness value, and the other having the smaller average thickness has the largest thickness value, and the smallest thickness value is smaller than the largest thickness value. Referring to fig. 4, in some embodiments, the maximum thickness of the thinned section 111 of any two adjacent thinned sections 111 distal from the second portion 12 is greater than the maximum thickness of the thinned section 111 proximal to the second portion; the support performance of this embodiment is superior.
Of course, in some embodiments as shown in fig. 5, the maximum thickness of the thinned section 111 away from the second portion 12 in any two adjacent thinned sections 111 may also be smaller than the maximum thickness of the thinned section 111 near the second portion; the bending performance of this embodiment is superior.
Further, referring to fig. 6 and 7, fig. 6 is a schematic structural view of another embodiment of the screen support of the present application, and fig. 7 is a sectional view taken along A-A in fig. 6. In some embodiments, a cavity 13 is formed in the screen support 1, and the cavity 13 extends in the length direction and penetrates at least part of the first portion 11; further, the cavity 13 extends through the whole screen support 1. The weight of the screen support 1 is reduced by arranging the cavity 13, and the weight reduction of the display module is facilitated.
Alternatively, in the width direction (Y direction) of the screen support 1, the cavities 13 are provided in plurality side by side. The cavities 13 may be arranged in one row or may be arranged in a plurality of rows in the thickness direction. Specifically, as shown in fig. 7, the panel support 1 is provided with a row of 5 cavities 13 juxtaposed in the Y-direction. The weight of the screen support 1 is further reduced by increasing the number of cavities 13; on the premise that the volumes of the cavities 13 are consistent, the cavities 13 which are arranged side by side along the Y direction have small influence on the moment of inertia of the screen support 1, and the bending resistance, shearing resistance and stretching resistance of the screen support 1 are ensured.
Alternatively, the cavity is rectangular in cross-section in the length direction. Compared with other cross-sectional shapes such as a circle, a polygon and the like, the rectangular cross-sectional cavity 13 is less prone to the problem of stress concentration, and the bending, shearing and stretching resistance of the screen support 1 is ensured.
Optionally, to ensure a light weight maximization of the screen support 1, the height h of the cavity 13 in the Z-direction i Can be varied with the height a of the corresponding penetrated thinned section 111 and/or the second part 12 i A variation is produced in which i=0, 1,2,3, …, which in turn corresponds to the height of the second portion 12 and the plurality of thinned sections 111, the width of the cavities 13 in the Y direction being x and the spacing of adjacent cavities 13 in the Y direction being s. Specifically, h i /a i ＝0.4～0.6，x≥h i ，s/a i ＝0.1～0.2。
Alternatively, in the length direction, the length b of the single thinned section 111 i Gradually increasing in the direction in which the average thickness of the plurality of thinned sections 111 decreases, where i=1, 2,3 …. Specifically, b i /b i+1 =0.6 to 0.8; specifically, a i /a i-1 ＝0.6～0.8. The smaller the average thickness, the longer the length of the thinned section 111, i.e. the closer to the bending center C, the smaller the thickness variation of the thinned section 111, which is beneficial to improving the flexibility of the screen support 1; the closer to the non-bending region B, the greater the thickness variation of the thinned section 111, which is advantageous for improving the rigidity of the screen support 1.
Further, referring to fig. 7, in some embodiments, the cavity 13 is filled with a stress buffering portion 131, where the stress buffering portion 131 includes an elastic material, and the elastic material may be a polymer material, such as acryl, polyurethane, rubber, and the like. The elastic material in the stress buffer part 131 can absorb the stress in the cavity when bending, so that the reliability is improved, and the flexibility of the screen support 1 is ensured.
Further, referring to fig. 8, in some embodiments, in the thickness direction (Z direction) of the screen support 1, the first portion 11 includes a first surface 113 and a second surface 114 that are oppositely disposed; the first surface 113 is formed by the upper surfaces of the thinned section 111 and the second part 12, and the step surface between the second part 12 and the upper surface of the thinned section 111, and the second surface 114 is formed by the lower surfaces of the first part 11 and the second part 12, and the step surface between the second part 12 and the lower surface of the thinned section 111, wherein when the screen support 1 is attached to the flexible screen 3, the first surface 113 is close to the flexible screen 3 relative to the second surface 114; optionally, the first surface 113 and the second surface 114 are each formed of a plurality of flat surfaces to ensure their resistance to bending, shearing and stretching; the first surface 113 has a first maximum level difference c 1 First maximum step c 1 For the maximum distance between the thinned section 111 and the upper surface of the second portion 12 in the thickness direction, the second surface 114 side has a second maximum step c 2 Second maximum level difference c 2 Is the maximum distance between the thinned section 111 and the lower surface of the second portion 12 in the thickness direction; specifically, as shown in fig. 8, the first maximum level difference c 1 May be the distance between the upper surface of the second portion 12 and the upper surface of the thinnest thinned section 111, and likewise, the second maximum difference c 2 May be the distance between the lower surface of the second portion 12 and the lower surface of the thinnest thinned section 111; first maximum step c 1 Less than the second maximum level difference c 2 . Alternatively, when the screen support 1 shouldFor a flexible screen module (for example, 360 ° bending screen) capable of being folded inwards and outwards simultaneously, because the bending radius of the inwards bending (indicated by the arrow in fig. 8) is smaller, the screen support 1 is close to the flexible screen 3, that is, the stress on the side close to the inwards bending is greater than that on the outwards bending side, and the breaking phenomenon is avoided by reducing the maximum step on the side close to the flexible screen 3, that is, reducing the thinning degree of the side, that is, setting the neutral layer of the screen support 1 to be close to the side of the flexible screen 3, so that the bending resistance of the screen support 1 during inwards bending is improved.
Further, with continued reference to fig. 8, in some embodiments, in the thickness direction of the screen support 1, the screen support 1 further includes a planarization layer 112, where the planarization layer 112 includes an elastic material, and the elastic material may be a polymer material, such as acryl, polyurethane, rubber, etc., and the planarization layer 112 is located on the first surface 113 to fill a level difference of the first surface 113; and/or the planarization layer 112 is located on the second surface 114 to fill the level difference of the second surface 114, that is, the outer surface of the planarization layer 112 is flush with the outer surface of the second portion 12. The arrangement of the flattening layer 112 increases the contact surface between the screen support 1 and the flexible screen 3 on one hand, and improves the support degree of the flexible screen 3; on the other hand, the elastic material of the planarization layer 112 can absorb the stress on the outer side of the thinned section 111, so as to improve the reliability; at the same time, the elastic material increases the elastic restoring ability of the panel support 1, and the thicker the planarization layer 112 is, the stronger the elastic restoring ability of the panel support 1 is, and the lighter the folds of the flexible panel when the flexible panel is restored from the bent or curled state is.
Referring to fig. 9-11, the applicant performed simulated data comparison of crease morphology, crease depth, and OCA gum layer stress conditions for 6 different screen support 1 structures (p 0-p 5). It should be noted that, the simulation data is a symmetric model built by taking the bending center C as a symmetry axis. Wherein the first portion 11 is not provided in p 0; the structure of p1-p3 is shown in FIG. 8, c in p1 1 ＝c 2 C in p2 2 C in p3 =0 1 =0; p4 and p5 are provided with only one thinned section 111, wherein a in p4 1 =54 μm, a in p5 1 =90 μm. FIG. 9 shows a lower crease of different configurations of the screen support of the present applicationComparing the simulation data of the morphology with a graph; FIG. 10 is a graph of data versus fold depth for different configurations of the screen support of the present application; FIG. 11 is a graph comparing the force data of the adhesive layer under different structures of the screen support of the present application.
It can be seen from fig. 9 to fig. 10 that the improvement effect of p3 on the crease is optimal, because the p3 design scheme can make the neutral layer closer to the flexible screen body 3, and for the inward folding flexible screen body 3, the extrusion stress of the flexible screen body 3 can be obviously improved; the p2 crease effect is the worst, but this solution would be advantageous for folding the flexible screen 3 outwards. As can be seen from fig. 10 to 11, p4 and p5 are designs in which only one thinned section 111 is provided, the difference between them being the thickness of the thinned section 111. Although this design can improve the support of the bending center C, the stress of the adhesive layer 2 increases, resulting in peeling.
Optionally, in some embodiments, in the length direction, the screen support 1 comprises at least one first portion 11, the at least one first portion 11 constituting a first group of portions; in the longitudinal direction, the screen support 1 includes a plurality of first partial groups in which the minimum thickness values of the thinned sections 111 decrease in sequence in the longitudinal direction. The screen support 1 can be applied to a multi-fold or roll-up display module.
Alternatively, referring to fig. 12, when the screen support 1 is applied to a multi-fold display module, each first portion group has a first portion 11, and corresponds to a refolding, the closer to the inner layer, the smaller the bending radius thereof, and the bending capability thereof is improved by increasing the thinning degree of the inner layer first portion group. Specifically, the screen support 1 includes three pieces, a first piece 1a is folded rightward over a second piece 1b, and a third piece 1c is folded leftward over the first piece 1 a; a bending area a is respectively arranged between the first sheet 1a and the second sheet 1b and between the second sheet 1b and the third sheet 1c, a first part 11 is respectively arranged corresponding to the bending area a, and the minimum thickness value of the first part of the left first part 11 is smaller than that of the right first part.
Optionally, when the screen support 1 is applied to the winding display module, the screen support 1 may be wound along the length direction, one turn of the wound screen support 1 corresponds to one first portion group, and the minimum thickness value of the first portion group located at the inner ring is smaller than the minimum thickness value of the first portion group located at the outer ring. The closer to the inner ring, the smaller the bending radius thereof, and the bending capability thereof is improved by increasing the thinning degree of the first portion group of the inner layer. Optionally, each first portion group has a plurality of first portions 11, and the first portions 11 may be uniformly distributed in the corresponding first portion group, so as to improve uniformity of flexibility of each turn of the screen support 1, and the number of first portions 11 in the first portion group may be selected according to an actual screen state.
With continued reference to fig. 8, the present application provides a display module, including a flexible screen 3 and a screen support 1 according to any one of the embodiments, where the flexible screen 3 and the screen support 1 are bonded by an adhesive layer 2, the adhesive layer 2 may be a transparent optical adhesive OCA, and the flexible screen 3 may be an OLED flexible screen or a micro-LED flexible screen. When the screen support 1 is attached to the flexible screen 3 through the adhesive layer 2, the adhesive layer 2 can be prevented from overflowing due to the fact that no opening is formed in the screen support 1, and the reliability of the display module is improved.
The foregoing is only the embodiments of the present application, and therefore, the patent scope of the application is not limited thereto, and all equivalent structures or equivalent processes using the descriptions of the present application and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the application.
