Optionally, when the panel supporting member 1 is suitable for a foldable display module, the number of the bendable regions a may be one or more than one, and each bendable region a may be provided with a bending center C. When the screen body supporting piece 1 and the flexible screen body are subsequently attached, the flexible screen body is bendable in the bendable region A, and the flexible screen body is not bendable in the non-bendable region B. Alternatively, when the screen support 1 is suitable for a winding-type display module, the number of the bendable regions a may be one, and subsequently, when the screen support 1 and the flexible screen are attached to each other, the flexible screen is windable in the bendable regions a.

The design mode can increase the flexibility of the screen body supporting piece 1 in the bendable area A and ensure the rigidity of the non-bendable area B.
Preferably, the at least one first portion 11 located in the bendable region a may be disposed axially symmetrically with respect to the bending center C. This design can make screen body support piece 1 use the center of buckling C as the axisymmetric setting at the flexibility of the district A that can buckle, guarantees the flexible screen body and buckles the unanimity of center C both sides crookedness when buckling.
And/or the thickness of the second portion 12 in the non-bending region C is the same in the length direction. The design mode can ensure that the rigidity of the screen body supporting piece 1 in the non-bending area B is arranged in an axisymmetric mode by taking the bending center C as the axis, and the evenness of the flexible screen body on the two sides of the bending center C is ensured to be consistent.
Further, the thickness of the single thinned section 111 remains uniform in the lengthwise direction. That is, the longitudinal section of the single thinning-out section 111 in the length direction Y is rectangular, the stress distribution under the rectangular section is more uniform, and the reliability of the screen support 1 is higher.

Of course, in other embodiments, the single thinning-out section 111 may be designed in other ways. For example, referring to fig. 4 and 5, the thickness of the single thinning-out section 111 is gradually reduced in a direction in which the average thickness of the plurality of thinning-out sections 111 is reduced in the length direction. 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 guaranteed; the longitudinal section of the thinning section 111 along the X direction can be trapezoidal, further, the longitudinal section is isosceles trapezoid, so that the gradual change of the inertia moment is ensured, and the over-concentration of stress is avoided.

Of course, in some embodiments as shown in fig. 5, the maximum thickness of the thinned section 111 far from the second portion 12 in any two adjacent thinned sections 111 may be smaller than the maximum thickness of the thinned section 111 near the second portion; the embodiment has better bending performance.
Further, referring to fig. 6 and 7, fig. 6 isbase:Sub>A schematic structural view of another embodiment of the screen support of the present application, and fig. 7 isbase:Sub>A cross-sectional view taken alongbase:Sub>A-base:Sub>A direction in fig. 6. In some embodiments, a cavity 13 is formed in the panel support 1, the cavity 13 extending along the length direction and penetrating at least a portion of the first portion 11; further, the cavity 13 extends through the entire screen support 1. This embodiment alleviates the weight of screen body support piece 1 through setting up cavity 13, is favorable to the lightweight of display module assembly.
Alternatively, the cavity 13 is provided in plurality side by side in the width direction (Y direction) of the panel support 1. The cavities 13 may be arranged in a single row or in a plurality of rows in the thickness direction. Specifically, as shown in fig. 7, the screen support 1 is provided with a row of 5 cavities 13 in parallel in the Y direction.

Alternatively, the cavity is rectangular in cross-section in the length direction. Compared with other cross-sectional shapes such as round, polygonal and the like, the rectangular cross-sectional cavity 13 is less prone to stress concentration problems, and the bending, shearing and stretching resistance of the screen support 1 is guaranteed.
Optionally, to ensure screen support1 maximum light weight, height h of the cavity 13 in Z-direction i May follow the height a of the corresponding thinned segment 111 and/or second portion 12 i A variation is produced wherein i =0,1,2,3 …, in turn corresponds to the height of the second portion 12 and the plurality of thinned sections 111, the width of the cavity 13 in the Y direction is x, and the gap between adjacent cavities 13 in the Y direction is s.

The smaller the average thickness, the longer the length of the thinning section 111 is, i.e. the closer to the bending center C, the smaller the thickness variation of the thinning section 111 is, and the design is favorable for improving the flexibility of the screen body supporting member 1; the closer to the non-bent region B, the greater the thickness variation of the thinned section 111, which is beneficial to 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, and the stress buffering portion 131 includes an elastic material, which may be a polymer material, such as acrylic, polyurethane, rubber, and the like. The elastic material in the stress buffering portion 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 a thickness direction (Z direction) of the screen support 1, the first portion 11 includes a first surface 113 and a second surface 114 disposed opposite to each other; the first surface 113 is formed by upper surfaces of the thinned section 111 and the second portion 12, and a step surface between the second portion 12 and the upper surface of the thinned section 111, and the second surface 114 is formed by lower surfaces of the first portion 11 and the second portion 12, and a step surface between the second portion 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 by a plurality of planes to ensure resistance to bending, shearing and stretchingForce; the first surface 113 has a first maximum step c on one side 1 First maximum step difference c 1 The second surface 114 side has a second maximum step c for the maximum distance between the thinned section 111 and the upper surface of the second portion 12 in the thickness direction 2 Second maximum step 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 reduced section 111, and similarly, the second maximum step 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 a second maximum step c 2 . Optionally, when screen body support piece 1 is applied to the flexible screen module that can infolding and roll over simultaneously (for example 360 the screen of buckling), because the bend radius of infolding (the arrow in fig. 8 indicates) is less, screen body support piece 1 is close to flexible screen body 3, be close to promptly that infolding one side receives stress and be greater than outer book one side, through reducing the biggest segment difference that is close to flexible screen body 3 one side, reduce the degree of thinning of this side promptly, be about to set up the neutral layer of screen body support piece 1 to be close to flexible screen body 3 one side, anti bending capability when promoting screen body support piece 1 infolding, avoid producing the fracture phenomenon.
Further, with reference to fig. 8, in some embodiments, in the thickness direction of the panel supporting member 1, the panel supporting member 1 further includes a planarization layer 112, the planarization layer 112 includes an elastic material, the elastic material may be a polymer material, such as acrylic, polyurethane, rubber, etc., and the planarization layer 112 is located on the first surface 113 to fill up the step of the first surface 113; and/or, the planarization layer 112 is disposed on the second surface 114 to fill the level difference of the second surface 114, i.e. the outer surface of the planarization layer 112 is flush with the outer surface of the second portion 12. The arrangement of the planarization layer 112 increases the contact surface between the screen support 1 and the flexible screen 3, 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 outside the thinning section 111, thereby improving the reliability; meanwhile, the elastic recovery capability of the screen support 1 is increased by the elastic material, the thicker the flattening layer 112 is at the position closer to the bending center, the stronger the elastic recovery capability of the screen support 1 is, and the lighter the crease when the flexible screen recovers from the bending or curling state.
Referring to fig. 9-11, the applicant performed comparison of simulation data on the crease appearance, crease depth and OCA glue layer stress of 6 different screen support 1 structures (p 0-p 5). It should be noted that the simulation data is a symmetric model constructed by using the bending center C as a symmetric axis. Wherein the first portion 11 is not provided in p 0; p1-p3 Structure referring to FIG. 8, c in p1 1 ＝c 2 In p2 c 2 =0, c in p3 1 =0; p4 and p5 are provided with only one thinning section 111, wherein a in p4 1 =54 μm, a in p5 1 =90 μm. FIG. 9 is a graph comparing simulation data of the fold profile of different configurations of the screen support of the present application; FIG. 10 is a data comparison plot of crease depth for different configurations of screen supports of the present application; FIG. 11 is a graph comparing the stress data of the adhesive layer under different structures of the screen support member.
From fig. 9-10, it can be seen that the improvement effect of p3 on the crease is optimal, because the p3 design solution can make the neutral layer closer to the flexible screen body 3, and for the flexible screen body 3 folded inwards, the extrusion stress of the flexible screen body 3 can be obviously improved; p2 creasing has the least effect, but this solution would be advantageous for folding the flexible screen body 3 outwards. As can be seen from fig. 10 to 11, p4 and p5 are designs in which only one thinning-out section 111 is provided, and the difference between the two designs is the thickness of the thinning-out section 111. This design can improve the support of the bending center C, but leads to an increase in the stress on the adhesive layer 2, resulting in peeling.
Optionally, in some embodiments, in the length direction, the screen support 1 includes at least one first portion 11, and the at least one first portion 11 constitutes a first group; in the length direction, the screen support 1 includes a plurality of first portion groups, and the minimum thickness values of the thinned sections 111 in the plurality of first portion groups decrease sequentially along the length direction. The screen support 1 can be applied to a multi-folding or winding display module.
Alternatively, referring to fig. 12, when the panel supporting member 1 is applied to a multi-folding display module, each first portion group has a first portion 11 corresponding to a refold, and the closer to the inner layer, the smaller the bending radius is, and the higher the bending capability is by increasing the thinning degree of the inner first portion group. Specifically, the screen support 1 comprises three sheets, a first sheet 1a being folded right over a second sheet 1b, and a third sheet 1c being folded left over the first sheet 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 11 on the left side is smaller than that on the right side.
Optionally, when the screen support 1 is applied to a winding type display module, the screen support 1 may be wound along a length direction, one turn of the wound screen support 1 corresponds to one first portion group, and a minimum thickness value of the first portion group located at the inner ring is smaller than a 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 group has a plurality of first portions 11, the first portions 11 may be uniformly distributed in the corresponding first group to improve uniformity of flexibility of each circle of the screen support 1, and the number of the first portions 11 in the first group may be selected according to an actual screen state.
Continuing to refer to fig. 8, the application provides a display module, including the flexible screen body 3 of range upon range of setting and the screen body support piece 1 of any item in the embodiment, flexible screen body 3 and screen body support piece 1 bond through glue film 2, and glue film 2 can be transparent optical cement OCA, and flexible screen body 3 can be flexible screen body of OLED or micro-LED flexible screen body etc.. When the screen body support piece 1 passes through the laminating of glue film 2 with the flexible screen body 3, because there is not the trompil on the screen body support piece 1, so can avoid glue film 2 to spill over, promote display module's reliability.
