DETAILED DESCRIPTION

[0052] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to the examples set forth here; rather, these embodiments are provided so that this disclosure will be comprehensive and complete, and the concept of exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed descriptions will be omitted. Further, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0053] Although relative terms are used in the present description, for example, on and below are used to describe the relative relationship of one assembly of a reference number to another assembly, these terms are used in the present description for convenience only, e.g., according to the direction of examples depicted in the figures. It can be appreciated that if the device of a reference number is turned upside down, the assembly described as above will become the assembly below. When a structure is on other structures, it may mean that the structure is integrally formed on other structures, or that the structure is directly provided on other structures, or that the structure is indirectly provided on other structures through another structure.

[0054] The terms a, an, the, said and at least one are used to indicate the presence of one or more elements/components/etc. The terms comprise and include are used to indicate an open-ended inclusion and mean that additional elements/components/etc. may be present in addition to listed elements/components/etc. The terms first, second, third and the like are used as tags only and are not intended to limit the number of objects after them.

[0055] Referring to FIGS. 1 and 2, before a cover plate 2 is laminated to a display panel 1, a non-display surface of the display panel 1 may usually be laminated onto a support plate 3, and then the support plate 3 is laminated onto a carrier film 8 (the length of the carrier film 8 is greater than the length of the display panel 1); and pull is applied to both ends of the carrier film 8, and then a part of the carrier film 8 is surrounded on a slider 11, so that the carrier film 8, the support plate 3 and the display panel 1 form a shape similar to the outer contour of the slider 11, for example, in the arc region of the slider 11, the carrier film 8, the support plate 3 and the display panel 1 all form arcs. The aforementioned process is called profiling. In this process, since the display panel 1 and the support plate 3 have certain rebound force effect in the arc region of the slider 11, the display panel 1 and the support plate 3 may warp and bulge to a certain extent, so that there is a relatively large gap between the display panel 1 and the slider 11, and distance between two opposite planar portions of the display panel increases after profiling, but the height of the space of the cover plate 2 for accommodating the display panel 1 may not change, resulting in the slider 11 being unable to successfully drive the carrier film 8, the support plate 3 and the display panel 1 to enter into the accommodation space of the cover plate 2. Moreover, it is not easy to laminate the cover plate 2 with the display panel 1 when the slider 11 drives the display panel 1 to move in the lamination process, and in the lamination process of the cover plate 2 and the display panel 1, bubbles are easily generated and wrinkles may be produced.

[0056] An exemplary embodiment of the present disclosure provides a display device, and referring to FIG. 2, the display device may include the cover plate 2, the display panel 1 and the support plate 3. The cover plate 2 includes at least a first planar portion 21, a second planar portion 22 and a first curved portion 23. The first curved portion 23 is smoothly connected between the first planar portion 21 and the second planar portion 22. The second planar portion 22 is parallel to the first planar portion 21. The first curved portion extends along a first direction, and an orthographic projection of the first curved portion 23 on a first datum plane is an arc. The first datum plane is perpendicular to the first direction. The first planar portion 21, the second planar portion 22 and the first curved portion 23 enclose an accommodation space. The display panel 1 is provided in the accommodation space. The support plate 3 includes at least a first straight support portion 3a, a first cambered support portion 3b and a second straight support portion 3c connected in sequence. The modulus of the first cambered support portion 3b is less than the modulus of the first straight support portion 3a, and the modulus of the first cambered support portion 3b is less than the modulus of the second straight support portion 3c. The first straight support portion 3a is laminated to one side of the display panel 1 away from the first planar portion 21, the first cambered support portion 3b is laminated to one side of the display panel 1 away from the first curved portion 23, and the second straight support portion 3c is laminated to one side of the display panel 1 away from the second planar portion 22.

[0057] In the display device of the present disclosure, the modulus of the first cambered support portion 3b is less than the modulus of the first straight support portion 3a, and the modulus of the first cambered support portion 3b is less than the modulus of the second straight support portion 3c; and the first straight support portion 3a is laminated to one side of the display panel 1 away from the first planar portion 21, the second straight support portion 3c is laminated to one side of the display panel 1 away from the second planar portion 22, so that the support plate 3 have sufficient strength to achieve the effect of supporting the display panel 1. The first cambered support portion 3b is laminated to one side of the display panel 1 away from the first curved portion 23, causing the support plate 3 to have sufficient flexibility to prevent the support plate 3 from warping and bulging easily during bending, so that warping and bulging of the display panel 1 is avoided, the distance between two opposite planar portions of the display panel 1 may not increase after profiling, and the slider 11, the carrier film 8, the support plate 3 and the display panel 1 can successfully enter into the cover plate 2. Moreover, the display panel 1 and the slider 11 are tightly laminated, so that it is easy for the cover plate 2 to be laminated with the display panel 1 when the slider 11 drives the display panel 1 to move in the lamination process, and in the lamination process of the cover plate 2 and the display panel 1, bubbles are not easily generated nor wrinkles may be produced.

[0058] The cover plate 2 may be a surround-shaped cover plate 2.

[0059] The present exemplary embodiment, referring to FIG. 3, the cover plate 2 may include the first planar portion 21, the first curved portion 23 and the second planar portion 22. The first planar portion 21, the first curved portion 23 and the second planar portion 22 are connected in sequence to form a U shape.

[0060] Specifically, the first planar portion 21 may be provided in rectangle and the first planar portion 21 may include a first plane and a second plane oppositely disposed. The first curved portion 23 is smoothly connected to one side of the first planar portion 21, for example, the first curved portion 23 may smoothly connected to a long side of the first planar portion 21, so that the first curved portion 23 extents along the long side of the first planar portion 21. Of course, in other exemplary embodiments of the present disclosure, the first curved portion 23 may smoothly connected to a short side of the first planar portion 21, so that the first curved portion 23 extents along the short side of the first planar portion 21. The first planar portion 21 may also be provided in other shapes. The extending direction of the first curved portion 23 is consistent with the extending direction of an edge of the first planar portion 21 which is an edge of the first planar portion 21 and is connected with the first curved portion 23. The first curved portion extents along the first direction, and the first direction is the extending direction of the axis corresponding to the cambered surface formed by the first curved portion.

[0061] The orthographic projection of the first curved portion 23 on the first datum plane is an arc, for example, a semi-circular arc, a semi-elliptical arc, a parabolic arc, etc. The first datum plane is perpendicular to the extending direction of the first curved portion, i.e., the first datum plane is perpendicular to the first direction. That is, the first datum plane is perpendicular the foregoing edge which is the edge of the first planar portion 21 and is connected with the first curved portion 23. Specifically, the first curved portion 23 may include a first curved surface and a second curved surface oppositely disposed. An orthographic projection of the first curved surface on the first datum plane is a semi-circular arc line, and an orthographic projection of the second curved surface on the first datum plane is also a semi-circular arc line. The two semi-circular arc lines are parallel to each other, and the two semi-circular arc lines are connected to form a semi-circular arc.

[0062] The first curved surface is connected to the first plane, and the first curved surface is tangent to the first plane. The second curved surface is connected to the second plane, and the second curved surface is tangent to the second plane. In this way, the first curved portion 23 is smoothly connected to the first planar portion 21.

[0063] The second planar portion 22 may also be provided in rectangle. The second planar portion 22 is smoothly connected to the other opposite side of the first curved portion 23, and the second planar portion 22 is parallel with the first planar portion 21. The second planar portion 22 may include a third plane and a fourth plane oppositely disposed. The third plane may be connected to the first curved surface, and the first curved surface is tangent to the third plane. The fourth plane is connected to the second curved surface, and the second curved surface is tangent to the fourth plane. In this way, the first curved portion 23 is smoothly connected to the second planar portion 22.

[0064] In the present exemplary embodiment, the width of the second planar portion 22 may be equal to the width of the first planar portion 21. The length of the first curved portion 23 and the length of the second planar portion 22 may be equal to the length of the first planar portion 21. Of course, in other exemplary embodiments of the present disclosure, the width of the second planar portion 22 may be different from the width of the first planar portion 21, and the length of the first curved portion 23 and the length of the second planar portion 22 may be different from the length of the planar portion 21.

[0065] It should be noted that, referring to FIG. 7, the length direction Y is the direction consistent with the extending direction of the first curved portion 23, and the width direction X is the direction perpendicular to the extending direction of the first curved portion 23. Of course, the thickness direction Z is also perpendicular to the extending direction of the first curved portion 23, but the thickness direction Z is consistent with the direction of the separation distance between the first planar portion 21 and the second planar portion 22. The length direction Y is the first direction, and the width direction X is the second direction.

[0066] Continuing to refer to FIG. 2, the display panel 1 is provided in the accommodation space of the cover plate 2. The portion of the display panel 1 corresponding to the first planar portion 21 is a first planar region, the portion of the display panel 1 corresponding to the first curved portion 23 is a curved region, and the portion of the display panel 1 corresponding to the second planar portion 22 is a second planar region. Since the first planar portion 21 is parallel to the second planar portion 22, the first planar region of the display panel 1 is also parallel to the second planar region of the first planar region. Moreover, since the width of the second planar portion 22 is equal to the width of the first planar portion 21, the width of the first planar region of the display panel 1 is also equal to the width of the second planar region of the first planar region.

[0067] The display surface of the display panel 1 is laminated to the inner surface of the cover plate 2, and specifically, the display surface of the display panel 1 is laminated to the inner surface of the cover plate 2 though a first adhesive layer 4. The first adhesive layer 4 may be an optically clear adhesive (OCA).

[0068] It should be noted that, the accommodation space of the cover plate 2 refers to a semi-enclosing structure formed by connecting the first curved portion 23 with the first planar portion 21 and the second planar portion 22 at one side where the center of a circle of the first curved portion 23 is located, and the accommodation space of the semi-enclosing structure is the accommodation space of the cover plate 2.

[0069] The support plate 3 is provided on one side of the display panel 1 away from the cover plate 2, i.e., the support plate 3 is provided on one side of the display panel 1 opposite to the display surface. The support plate 3 supports the display panel 1.

[0070] Specifically, referring to FIGS. 4 and 5, the support plate 3 may include a first layer 31, a second layer 32 and a third layer 33. The first layer 31 is provided on one side of the display panel 1 away from the cover plate, the second layer 32 is provided on one side of the first layer 31 away from the cover plate, and the second layer 32 is also provided on one side of the first layer 31 away from the cover plate.

[0071] Specifically, the first layer 31 may include a first part 311, a second part 312 and a third part 313 connected in sequence. The second part 312 forms the first cambered support portion 3b, and the second part 312 is laminated to one side of the display panel 1 away from the first curved portion. The thickness of the second part 312 is greater than the thickness of the first part 311, and the thickness of the second part 312 is greater than the thickness of the third part 313. Of course, the thickness the first part 311, the second part 312 and the third part 313 may be equal.

[0072] The second layer 32 is provided on one side of the first part 311 away from the display panel 1, and the second layer 32 and the first part 311 form the second straight support portion 3c, i.e., the second straight support portion 3c may include the second layer 32 and the first part 311. The modulus of the first layer 31 is less than the modulus of the second layer 32, so that the modulus of the second straight support portion 3c is greater than the modulus of the first cambered support portion 3b.

[0073] The third layer 33 is provided on one side of the third part 313 away from the display panel 1, and the third layer 33 and the third part 313 form the first straight support portion 3a, i.e., the first straight support portion 3a may include the third layer 33 and the third part 313. The modulus of the first layer 31 is less than the modulus of the third layer 33, so that the modulus of the first straight support portion 3a is greater than the modulus of the first cambered support portion 3b.

[0121] Step S10, adhering the support plate 3 and the display panel 1 in sequence on one surface of the carrier film 8; and forming the first adhesive layer 4 on one side of the display panel 1 away from the carrier film 8.

[0122] Step S20, surrounding the carrier film 8 outside the slider 11, and clamping, by the clamp portion 9, two opposite ends of the carrier film 8 for profiling of the display panel.

[0123] Step S30, driving, by the mechanical arm 10, the slider 11 to move to the accommodation space of the cover plate 2 along the third direction.

[0124] Step S40, driving, by the mechanical arm 10, the slider 11 to move along the fourth direction, so that the display panel 1 is in contact with the first curved portion, and driving, by the mechanical arm 10, the slider 11 to slide along the first curved portion to complete the lamination between the display panel 1 and the first curved portion.

[0125] Step S50, driving, by the mechanical arm 10, the slider 11 to move along the direction perpendicular to the first planar portion to complete the lamination between the display panel 1 and the first planar portion.

[0126] The lamination method will be described in detail below.

[0127] It is noted that, the carrier film 8 surrounds outside the slider 11 refers to that the carrier film 8 surrounds substantially three surfaces of the slider 11 without completely surrounding the slider 11.

[0128] The support plate 3 is laminated on one surface of the carrier film 8, the third adhesive layer 7 is laminated on one surface of the support plate 3 away from the carrier film 8, the protective layer 5 is laminated on one surface of the third adhesive layer 7 away from the carrier film 8, the second adhesive layer 6 is coated on one surface of the protective layer 5 away from the carrier film 8, the display panel 1 is laminated on one surface of the second adhesive layer 6 away from the carrier film 8, and the first adhesive layer 4 is coated on one surface of the display panel 1 away from the carrier film 8.

[0129] The adhesive force between the support plate 3 and the protective layer 5 is 12 N/25 mm.sup.2, i.e., the adhesive force of the third adhesive layer 7 is 12 N/25 mm.sup.2. The adhesive force between the support plate 3 and the carrier film 8 is 2000 gf/inch, and after UV sticky reduction, the adhesive force<10 gf/inch. The adhesive force between the support plate 3 and the carrier film 8 is less than the adhesive force between the support plate 3 and the protective layer 5, so that after the lamination of the display panel 1 is completed, the support plate 3 will not be peeled off the protective layer 5 when the carrier film 8 is peeled off the support plate 3,.

[0130] Referring to FIGS. 5, 11, and 12, the carrier film 8 is placed around the outside of the slider 11, and the carrier film 8 is passed through the first gap 112, or the carrier film 8 is passed through the first gap 112 and the second gap 113; and the opposite ends of the carrier film 8 are clamped through the clamp portion 9, so that the carrier film 8 is tensioned for profiling the display panel 1.
