The protection scope of the present application is defined by the appended claims.

[0054] Please refer to Figures 1-3, Figure 1 This is a front view of an inward-folding screen in related technologies. Figure 2 This is a rear view of an inward-folding screen in related technologies. Figure 3 This is a solution for implementing the main and secondary screens of an inward-folding screen in related technologies. For example... Figures 1-3 As shown, the inward-folding screen includes a main screen 1' and a secondary screen 2', as follows: Figure 1 The main screen 1' shown is located on the front of the inward-folding screen. When the inward-folding screen is unfolded, information can be exchanged using the main screen 1'. The main screen 1' has a bendable area, allowing it to fold inwards. Figure 2 The secondary screen 2' shown is located on the back of the inward folding screen. A camera area is also located on the back of the inward folding screen. The camera area does not overlap with the secondary screen 2'.

[0055] like Figure 3 The main screen 1' and the secondary screen 2' shown are respectively set on two display modules, and each display module is equipped with a driver chip (not shown) and a corresponding flexible circuit board 3' connected to the motherboard (not shown), so that the main screen 1' and the secondary screen 2' can achieve split-screen control, and the secondary screen 2' can achieve information interaction without opening the main screen 1'; however, this design makes the production cost of the inward folding screen high and is not conducive to the realization of a narrow bezel design.

[0056] Furthermore, since the flexible circuit board 3' corresponding to the secondary screen 2' will further occupy the motherboard space, it is difficult to compress the overall thickness of the device.

[0057] To address the aforementioned problems, this utility model provides a display module, which will be described in detail below with reference to the accompanying drawings.

[0058] Please see Figures 4-6 , Figure 4 and Figure 5 This is a side view schematic diagram of a display module provided by this utility model. Figure 6 This is a flattened schematic diagram of a display panel provided in an embodiment of the present utility model. The display module includes:

[0059] Support member 1 includes a main support part 11 and a secondary support part 12 disposed opposite to each other, and a transition support part 13 connecting the main support part 11 and the secondary support part 12; the transition support part 13 includes a first support part 131 disposed in the thickness direction Z of the display module, and the main support part 11 and the secondary support part 12 are both located on the same side of the first support part 131.

[0060] Display panel 2 has a main screen area 21, a transition area 22, and a secondary screen area 23 connected in sequence, such as Figure 6As shown, in the first direction X, the transition area 22 is recessed relative to the sub-screen area 23 and the main screen area 21; the main screen area 21 includes at least two sub-areas 211 and at least one bendable area 212, the bendable area 212 is connected between two adjacent sub-areas 211, and the display panel can be folded along a folding axis OO' parallel to the first direction X in the bendable area 212; the main screen area 21 has a main screen display area AA1, the sub-screen area 23 has a sub-screen display area AA2, the main screen display area AA1 overlaps with the sub-areas 211 and the bendable area 212; the portion of the display panel 2 located in the main screen area 21 is attached to the main support 11, the portion of the display panel 2 located in the sub-screen area 23 is attached to the sub-support 12, the portion of the display panel 2 located in the transition area 22 is at least attached to the transition support 13, and the light-emitting surface of the main screen display area AA1 and the light-emitting surface of the sub-screen display area AA2 are arranged opposite to each other; wherein, the first direction X is the extension direction of the display panel (i.e., Figure 6 The Y direction shown in ) is vertical;

[0061] The driving circuit 3 is located at the end near the main screen area 21 or the secondary screen area 23 away from the transition area 22. The driving circuit 3 is used to provide data signals to the data line connecting the main screen area 21, the transition area 22 and the secondary screen area 23.

[0062] The display panel 2 can be a flexible display panel 2, which makes it easy to fit with the support member 1; if the display panel 2 is a non-flexible display panel 2, then the part of the display panel 2 located in the transition area 22 is flexible.

[0063] The portion of the display panel 2 located in the transition area 22 does not emit light. This portion of the display panel 2 located in the transition area 22 can have the same film layer structure as the display panel 2 located in the main screen area 21, or it can only have the same film layer as a portion of the display panel 2 in the main screen display area AA1. This portion of the film layer includes the film layer where the data line is located. This can reduce the thickness of the display panel 2 in the transition area 22, thereby improving the bendability of the display panel 2 at the corner between the main support part 11 and the thickness support part, the bendability at the corner between the secondary support part 12 and the thickness support part, and further realizing a smaller narrow bezel design.

[0064] like Figure 4 As shown, the support member 1 can be formed by bending the main support part 11 and the secondary support part 12 by 180° to form the transition support part 13. The side view of the transition support part 13 is arc-shaped, and the transition support part 13 is the first support part 131.

[0065] like Figure 5As shown, the support member 1 can be formed by bending the area between the transition support part 13 and the main support part 11, or the area between the transition support part 13 and the secondary support part 12, by 90°, or it can be an integral structure formed by injection molding. The specific shape of the support member 1 is not limited here. The first support part 131 is the portion of the transition support part 13 parallel to the thickness direction Z of the display module. The support member can also be made of materials such as glass or carbon fiber.

[0066] Please continue reading Figure 5 Since both the main support 11 and the secondary support 12 are located on one side of the first support 131 and are perpendicular to it, and the display panel 2 is attached to the first surface 1a of the support member 1, with the portion of the display panel 2 in the main screen area 21 attached to the main support 11, the portion of the display panel 2 in the secondary screen area 23 attached to the secondary support column, and the portion of the display panel 2 in the transition area 22 attached to the transition support 13, a bend from the main screen area 21 to the secondary screen area 23 can be achieved through two (90°) bends, reducing the degree of bending in the transition area 22 in a single instance. Figure 4 The display panel 2 bends 180° directly from the main screen area 21 to the secondary screen area 23, which greatly reduces the gap between the display panel 2 in the transition area 22 and the transition support 13. This effectively reduces the upper bezel width of the main screen area 21 and the secondary screen area 23, achieving a narrow bezel design. Furthermore, since the secondary screen area 23 and the main screen area 21 use the same data line and drive circuit 3, compared to… Figure 3 The split design can save a set of flexible circuit boards 4 and driving circuits 3, thereby effectively reducing the production cost of the display module, reducing the space occupied by the motherboard (not shown) in the display module, and reducing the overall thickness.

[0067] The main support part 11 is designed to be flexible at the position corresponding to the bendable area 212. The bendable design scheme in the prior art can be adopted so that the main support part 11 can be folded at the position corresponding to the bendable area 212.

[0068] It should be noted that, in Figure 6 The main screen area 21 shown includes two bendable areas 212. In fact, the main screen area 21 may also include one bendable area 212 or more bendable areas 212, but usually the number of bendable areas 212 included in the main screen area 21 is one less than the number of sub-areas 211 included in the main screen area 21.

[0069] In the embodiment of the utility model, through setting the support piece 1 as the main support part 11 and the auxiliary support part 12 and the transition support part 13 connecting the main support part 11 and the auxiliary support part 12, the transition support part 13 includes the first support part 131 arranged on the display module thickness direction Z, and the main support part 11 and the auxiliary support part 12 are located on one side of the first support part 131; at the same time, the display panel 2 is pasted with the main support part 11, the transition support part 13 and the auxiliary support part 12 in the main screen area 21, the transition area 22 and the auxiliary screen area 23 in sequence, the data driving circuit box connects the data line of the main screen area 21, the transition area 22 and the auxiliary screen area 23 to provide the data signal, so that the display panel 2 uses the same data line data and driving circuit 3 in the auxiliary screen area 23 and the main screen area 21, therefore compared with the scheme that the main screen and the auxiliary screen are designed in the related art, a group of flexible circuit board 4 and driving circuit 3 can be saved, the production cost of the display module can be effectively reduced, the space occupation of the mainboard (not shown) in the display module is reduced, and the overall thickness is reduced. In the first direction X, the transition area 22 is arranged in the main screen area 21 and the auxiliary screen area 23, so that the damage of the display panel 2 at the edge of the transition area 22 can be prevented.

[0070] Please refer to Figure 7 and Figure 8 , Figure 7 The utility model provides a structural diagram of a display module, Figure 8 The utility model provides Figure 7 The flattened schematic view of the support piece in the embodiment of the utility model.

[0071] The transition support part 13 further includes:

[0072] Two deformation parts 132, one deformation part 132 is connected between the main support part 11 and the first support part 131; the other deformation part 132 is connected between the auxiliary support part 12 and the first support part 131;

[0073] The deformation part 132 is provided with a plurality of hollow holes K arranged in an array, the hollow holes K extend along the first direction X, and adjacent two hollow holes K arranged along the second direction Y are arranged in a staggered manner; wherein, the first direction X and the second direction Y are orthogonal. The second direction Y is also the extension direction of the support piece 1.

[0074] By arranging a plurality of hollow holes K arranged in an array in the deformation part 132, the hollow holes K extend along the first direction X, and adjacent two hollow holes K arranged along the second direction Y are arranged in a staggered manner; Figure 8The plurality of hollow holes K are arranged in a staggered manner (as shown in the dashed-dotted box) so that when the deformation portion 132 is pressed, the plurality of hollow holes K are deformed to reduce the length of the hollow holes K in the second direction Y, and the deformation portion 132 is contracted; when the deformation portion 132 is stretched, the plurality of hollow holes K are deformed to increase the length of the hollow holes K in the second direction Y, and the deformation portion 132 is elongated, and finally the deformation portion 132 realizes the telescopic function.

[0075] The hollow holes K can be long strips, so that the deformation portion 132 is easy to realize the telescopic function in the second direction Y; the corners of the long strips can be arc-shaped transitions, so as to reduce the stress at the corner positions and improve the fatigue resistance. Of course, the hollow holes K can also be other shapes, which are not limited here.

[0076] Please continue to see Figure 8 In the second direction Y, the length l of the transition support portion 13 is greater than or equal to πD / 2+1mm, where D is the thickness of the display module, so as to ensure the ductility of the support 1 at the transition support portion 12.

[0077] In some embodiments, in the second direction Y, the length l' of the first support portion 131 is less than the thickness of the display module, and the length of the deformation portion 132 ranges from 1mm to 10mm.

[0078] In other embodiments, the elastic modulus of the deformation portion 132 is less than 6MPa, and the elastic modulus of the first support portion 131 is greater than 6MPa, so that the deformation amount of the first support portion 131 is smaller than that of the deformation portion 132. When the deformation portion 132 is bent, it is easy to form the required bending angle; when the transition support portion 13 is bent as a whole, it is also easy to bend, and when the transition support portion 13 is restored from the bent state to the flat state under the action of external force, it is also easy to rebound. Thus, the part of the main support portion 11 corresponding to the bendable area 212 can adopt the same pattern as the transition support portion 13, thereby improving the reusability of the pattern of the transition support portion 13 and improving the design efficiency of the support 1.

[0079] It should be noted that, Figure 8 The pattern of the part of the main support portion 11 corresponding to the bendable area 212 is not shown in the middle.

[0080] In the embodiment of the utility model, through setting transition support part 13 to still include two deformation parts 132 connected with main support part 11 and first support part 131, with deputy support part 12 and first support part 131 respectively, and setting multiple hollow holes K in array arrangement in deformation part 132, and letting hollow hole K extend along first direction X, and the adjacent two hollow holes K of arranging along second direction Y are misaligned, wherein, first direction X and second direction Y direction are orthogonal, like this can utilize the hollow hole K of setting in deformation part 132 to improve the easy bending property and scalability of deformation part 132, reduce the stress generated by bending.

[0081] Please see Figure 9 The flattening schematic view of another support provided by the embodiment of the utility model, in the edge near transition support part 13, the adjacent two hollow holes K of arranging along second direction Y misalign, one is first hollow hole K1, and the other is second hollow hole K2;First hollow hole K1 and edge line L of support 1 intersect (that is, first hollow hole K1 extends to the edge line L of support 1 and is communicated, so that deformation part 132 forms an opening in the edge where first hollow hole K1 is located), and second hollow hole K2 and edge line L of support 1 do not intersect;Wherein, the extension direction of edge line L of support 1 is the same as second direction Y.

[0082] The shape of first hollow hole K1 is long strip, and the corner of long strip is arc-shaped;The shape of second hollow hole K2 is partially the same as the shape of first hollow hole K1, such as the shape of second hollow hole K2 is the figure after cutting first hollow hole K1 along the center line of second direction Y, so that the deformation performance of deformation part 132 at edge position tends to be consistent.

[0083] In the embodiment provided by the utility model, by letting the part hollow hole K (first hollow hole K1) misaligned in the edge line L of support 1 in deformation part 132 and edge line L of support 1 intersect, the opening can be formed in the edge where first hollow hole K1 is located in deformation part 132, so that the scalability of deformation part 132 at edge position can be improved.

[0084] Please see Figure 9 The extension line of the area between the adjacent two hollow holes K in first direction X in second direction Y passes through the middle part KO of the hollow hole K adjacent to the adjacent two hollow holes K in second direction Y, so that the uniformity of stress of deformation part 132 at each position can be improved, and stress concentration can be prevented.

[0085] Please see Figure 9In the second direction Y, the width d1 of the center position of the long strip is the same as the interval d2 between the adjacent two hollow holes K, so that the deformation amount generated when the deformation part 132 is stretched and the deformation amount generated when the deformation part 132 is compressed tend to be consistent.

[0086] It should be noted that, Figure 9 The pattern of the part corresponding to the bendable area 212 in the main support part 11 is not shown in the middle.

[0087] Please refer to Figure 10 The structure of the deformation part after flattening provided by the embodiment of the utility model is shown in the schematic view, the deformation part 132 includes the main deformation part 1321 and the auxiliary deformation part 1322 which are arranged alternately along the second direction Y.

[0088] The plurality of hollow holes K are distributed in the main deformation part 1321, and the auxiliary deformation part 1322 is free of the hollow hole K; the arrangement mode and shape of the hollow hole K distributed in the main deformation part 1321 can adopt any one or any combination of the modes in the foregoing embodiments, which will not be described here.

[0089] By arranging the main deformation part 1321 and the auxiliary deformation part 1322 which are arranged alternately along the second direction Y in the deformation part 132, and distributing the plurality of hollow holes K in the main deformation part 1321 and not arranging the hollow hole K in the auxiliary deformation part 1322, the balance between the resilience and the bending performance of the deformation part 132 can be improved.

[0090] Please continue to refer to Figure 10 The width W1 of the main deformation part is at least twice the width W2 of the auxiliary deformation part 132, so that the balance between the bending and resilience of the deformation part 132 can be maintained.

[0091] In some embodiments, the hollow hole K is filled with an elastic material. For example, the hollow hole K in the main screen area 21 can be provided with the elastic material, and the elastic material can be the high polymer material used in the main screen area 21. By arranging the elastic material in the hollow hole K, the ductility of the transition support part 13 can be effectively improved. Figures 8-10

[0092] Please refer to Figure 11 The flattened view of another support provided by the embodiment of the utility model is shown in the schematic view.

[0093] The main support part 11 includes the bendable part 111 which is attached to the bendable area 212 of the display panel 2, and the pattern of the bendable part 111 is the same as that of the transition support part 13.

[0094] By setting the pattern of the bendable part 111 which is attached to the bendable area 212 of the display panel 2 in the main support part 11 to be the same as that of the transition support part 13, the design efficiency and the production efficiency can be improved. ​

Figure 12 The inward-folding screen includes a middle frame 8, a support member 1, a display panel 2, and a cover plate 7 stacked sequentially. The middle frame 8 and the support member 1, as well as the support member 1 and the display panel 2, are bonded together with adhesive 5. The display panel 2 and the cover plate 7 are bonded together with optical adhesive. The display panel 2 includes a viewable area VA and a display area AA located within the viewable area VA. On the side of the cover plate 7 near the display panel 2, an area outside the viewable area VA is coated with light-shielding ink 9. Due to the inward folding misalignment of the inward-folding screen, the inner edge of the cover plate 7 will elongate by more than 0.2 mm after folding. To avoid this area (… Figure 11 The area shown in the dashed box interferes with the middle frame 8. Therefore, buffer zones need to be left at the top and bottom of the middle frame 8 for avoidance design. The gap KK between the display area AA and the viewable area VA is increased (e.g., the gap between the display area and the viewable area in a conventional display is 0.2mm, while the gap between the display area AA and the viewable area VA in an inward-folding screen is 0.3mm) to allow for folding misalignment (i.e., the amount by which the cross-section of the film layer of the folding screen is stretched by the cover plate 7 when the inward-folding screen is folded inward). This makes the inward-folding screen unsuitable for narrow bezel design. The length of the gap is determined by the folding misalignment, the bonding accuracy between each film layer, the accuracy of the cover plate 7, and the accuracy of the ink 9.

[0096] Please see Figure 13 This is a top view of another main screen area provided in an embodiment of the present utility model. The main screen area 21 also includes a main screen visible area VA1, and the main screen display area AA1 is located within the main screen visible area VA1.

[0097] In the second direction Y, a gap KK is provided between the edge of the main screen display area AA1 and the edge of the main screen visible area VA1; the gap KK is larger than the gap between the display area and the visible area in a conventional display screen, and the gap KK can be 0.3mm;

[0098] The display panel 2 has a retractable pattern in the part corresponding to the transition area 22 (for example, the pattern provided in the transition support part 13 can be referred to above; the size of the pattern may be different, but the shape is the same). The pattern provided in the transition area 22 near the edge of the main screen area 21 and the sub-screen area 23 can at least enable the display panel 2 to have a compressible function near the aforementioned edge.

[0099] The display module also includes:

[0100] The middle frame 8 is located on the side of the support member 1 away from the display panel 2; the middle frame 8 is bonded to the support member 1 by adhesive 5; the display panel 2 is also bonded to the support member 1 by adhesive 5.

[0101] The cover plate 7 is located on the side of the display panel 2 away from the support member 1; the cover plate 7 is bonded to the display panel 2 by optical adhesive 6; the cover plate 7 does not cover the part of the display panel 2 in the transition area 22.

[0102] Because the support member 1 is provided with two deformable portions 132 in the transition support portion 13 along the first direction X ( Figure 13 Multiple perforated holes K (not shown) extending from the surface Figure 13 (Not shown), and two adjacent hollowed-out sections are staggered along the second direction Y, allowing the two deformable sections 132 to extend and retract in the first direction X. This, combined with the gap KK between the main screen visible area VA1 and the main screen display area AA1 in the first direction X of the display panel 2, enables the pattern in the deformable section 132 to absorb folding slippage when the main screen area 21 of the display panel 2 is foldable, even when the main screen area 21 of the display panel 2 also includes a bendable area 212. This eliminates the need for... Figure 12 Setting up a buffer zone in this way makes it impossible to achieve a narrow bezel design without improving manufacturing precision. Furthermore, since the pattern of the bendable portion 111 of the support member 1 is the same as the pattern of the transition support portion 13, the pattern in the bendable portion 111 can absorb some of the folding misalignment, further achieving a narrow bezel design.

[0103] In some embodiments, the transition support 13 absorbs 0.05 mm to 1 mm of folding misalignment.

[0104] Please refer to Figure 14 This is a schematic diagram of the shape of the data line in the transition area and the bendable area of ​​a display panel provided in an embodiment of the present invention. The part of the data line located in the transition area 22 and the bendable area is a wavy line. This makes the part of the data line located in the transition area 22 stretchable, thereby preventing the data line from breaking when the display panel 2 is bent in the transition area 22 and the bendable area, thus preventing it from failing to display normally and improving the reliability of the display panel 2.

[0106] The display module also includes:

[0107] Camera module A and sub-screen area 23 are located on the same side of the display module (i.e., both are located on the back of the display module); camera module A is located outside sub-screen area 23, or the display panel 2 is provided with a through hole H in sub-screen area 23, and camera module A is located in through hole H.

[0108] like Figure 15The camera module A shown can be arranged at one side of the sub-screen area 23, of course, can also be arranged at Figure 15 The other side shown, not limited here, such as Figure 16 The camera module A shown can also be half-enclosed by the sub-screen area 23, such as Figure 17 As shown, the display panel 2 is further provided with a through hole H penetrating the display panel 2 in the sub-screen area 23, and the camera module A can be arranged in the through hole H.

[0109] By arranging the camera module A and the sub-screen area 23 on the same side of the display module, and arranging the camera module A outside the sub-screen area 23, or arranging a through hole H penetrating the display panel 2 in the sub-screen area 23 of the display panel 2, and arranging the camera module A in the through hole H, the diversified design of the sub-screen area 23 can be realized, and the whole machine space can be saved.

[0110] The display panel 2 can be a liquid crystal display panel (LCD), an organic light emitting diode (OLED) display panel, a quantum dot light emitting diode (QLED) display panel, a micro light emitting diode (Micro LED) display panel, etc., and the present application does not make specific limitation hereon.
