For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Furthermore, the terms "first," "second," and the like are used primarily to distinguish one device, element, or component from another (the specific type and configuration of the device may be the same or different), and are not used to indicate or imply the relative importance or number of the indicated devices, elements, or components. "plurality" means two or more unless otherwise specified.
The quadric screen means as the name implies: on the basis that the left and right screens of the plane screen in the middle are bent, the curved screens at the upper end and the lower end are further added. That is, the four-curved-surface display screen has curved surfaces in four directions, namely, up and down, left and right directions, and compared with the double-curved-surface display screen, the four-curved-surface display screen has great improvement in performance in terms of screen occupation ratio and the like of the screen.
The inventor finds that when the quadric-curved screen is attached, the four corners of the quadric-curved screen have transverse and longitudinal bending overlapped areas, the display screen is compressed when the display screen is attached to enter the bending overlapped areas, the areas are called Gaussian corner areas (as shown in FIG. 1, FIG. 1 shows the Gaussian corner area A of the quadric-curved screen in the related art), and the display screen can be divided into false quadric and true quadric according to the area size of the display panel layer attached to enter the Gaussian corners.
The pseudo-quadric curve means that the display panel layer does not enter a gaussian angle area a or enters a small amount when being attached, so that the stress of the display panel layer is small, the strain of the whole display panel layer is also small, the risk of failure of film packaging is low, and the manufacture is easier, but the display panel layer has the defects that the display area of the display panel layer cannot cover the gaussian angle area a, and the screen occupation ratio and the display effect of a quadric curve screen are affected, as shown in (a) in fig. 2, and (a) in fig. 2 shows that the display panel layer does not enter the gaussian angle area a when being attached.
When the display panel layer is in a true-quartic state, that is, when the display panel layer is attached, the display panel layer enters a gaussian angle area a, and according to the requirement of the appearance of a cover plate covering the display panel layer, as the bending angle of the gaussian angle area a becomes larger, the stress deformation of the display panel layer tends to increase, and the reliability is seriously challenged, as shown in fig. 2 (b), which shows that the display panel layer completely enters the gaussian angle area.
As shown in fig. 3, fig. 3 is a schematic view showing a laminated structure of a quadric-curved panel in the related art, and the laminated structure of the quadric-curved panel in the related art is roughly as follows: the four-curved screen comprises a cover plate 1, an optical adhesive layer 2, a polarizer layer 3, a touch layer 4, a display panel layer 5, a PI film layer 6(polyimide film) and a screen lower supporting structure 7 which are sequentially stacked from top to bottom. The under-screen supporting structure 7 is mainly used for supporting the display panel layer 5, and plays a certain buffering role in the display panel layer 5 to prevent the display panel layer 5 from deforming.
With reference to fig. 4, fig. 4 is a schematic diagram illustrating a bonding process of a quad flat screen in the related art, and further, the bonding process of the quad flat screen in the related art is roughly as follows, first bonding the display panel layer 5 and the polarizer layer 3 together, then bonding a combination of the display panel layer 5 and the polarizer layer 3 with a PI film, fixing and stretching the display panel layer 5 through the PI film layer 6 to realize stretching, and then bonding the display panel layer 5 with the cover plate 1 through the silicone support block 8. At this time, the corner bonding position of the display panel layer 5 is in a free bonding state, and in the free bonding state, the free energy of the display panel layer 5 is the lowest, and the display panel layer 5 has little deformation, and the whole deformation is small because the whole thickness of the combination of the display panel layer 5 and the polarizer layer 3 is small.
After the display panel layer 5 is jointed with the cover plate 1, the display panel layer 5 jointed with the cover plate 1 is bonded with the under-screen supporting structure 7, wherein, the under-screen supporting structure 7 mainly comprises a buffer layer 7a and a metal layer 7b, wherein the buffer layer 7a is mainly used for resisting the condition that the display panel layer 5 fails due to falling or external impact, the metal layer 7b can not only be used for realizing the heat dissipation of the display panel layer 5, meanwhile, when the four-curved screen is arranged on the shell of a product, the metal layer 7b can be attached to the shell of the product, since various recesses or projections for avoiding electronic devices are provided in the housing of the product, attaching the metal layer 7b to the housing of the product can prevent the top print corresponding to the projections from being seen on the display panel layer 5 due to the impact or attachment stress of the recesses or projections on the housing of the product on the display panel layer 5. Therefore, due to the presence of the metal layer 7b of the under-screen support structure 7, the elastic modulus of the under-screen support structure 7 is much larger than that of the display panel layer 5, and when the under-screen support structure 7 is attached to the display panel layer, it is easier to bulge or arch in the corner area (i.e., gaussian corner area), which causes the display panel layer 5 to be also arched, which affects the attachment, and may even cause crushing of the display panel layer 5.
Based on this, if the under-screen supporting structure is directly cut off in the corner area B corresponding to the display panel layer, although the problems of arching, bulging and the like can be avoided, the corner area B is directly cut off, which may result in that the under-screen supporting structure cannot realize effective supporting, buffering and heat dissipation in the corner area B corresponding to the display panel layer, as shown in fig. 5, fig. 5 is a schematic diagram of directly cutting off the corner area B corresponding to the display panel layer with the under-screen supporting structure, and the cut corner area B is shown by a dotted line.
Therefore, in order to compromise and solve the corner region hunch-up of under-screen supporting structure on the display panel layer, the uplift, and do not have the support, there is not buffering, no heat dissipation scheduling problem, the embodiment of the application discloses an under-screen supporting structure, this under-screen supporting structure can be applied to the quadric crank screen, through weakening the elastic modulus in the corner region of the first metal level of under-screen supporting structure, thereby when laminating under-screen supporting structure in the display panel layer of quadric crank screen, can prevent this under-screen supporting structure from producing to corrugate and lead to crushing the display panel layer corresponding to display panel layer corner region, or lead to the unable normal condition of laminating of display panel layer hunch-up, effectively alleviate the stress concentration condition of quadric crank screen when laminating, improve the demonstration yield of quadric crank screen.
The specific structure of the under-screen support structure according to the embodiment of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 6 and 7 together, a first aspect of the present disclosure discloses a lower support structure for a screen, which may be applied to a quadric screen having a display panel layer, where the display panel layer may include a central display portion and a first corner portion connected to the central display portion. The quad screen is generally applicable to mobile terminals, such as mobile phones, tablet computers, and the like. Taking the application of the four-curved screen to a mobile phone as an example, the four-curved screen is generally rectangular, and therefore, the number of the first corner portions can be four, and the first corner portions are respectively located at the periphery of the central display portion. The under-screen support structure 10 includes a buffer layer 11 and a first metal layer 12, where the buffer layer 11 is used to connect the display panel layers. The first metal layer 12 is disposed on a side of the buffer layer 11 away from the display panel layer, the first metal layer 12 has a central supporting portion 12a and a second corner portion 12b connected to the central supporting portion 12a, the central supporting portion 12a is disposed corresponding to a central display portion of the display panel layer of the quad flat screen, the second corner portion 12b is disposed corresponding to a first corner portion of the display panel layer, and an elastic modulus of the second corner portion 12b is smaller than an elastic modulus of the central supporting portion 12 a.
The elastic modulus of the second corner part 12b of the first metal layer 12 is limited to be smaller than that of the central support part 12a, so that the second corner part 12b has certain deformation resistance compared with the central support part 12a, when the screen lower supporting structure 10 is attached to the display panel layer of the quadric curved screen, the situation that the screen lower supporting structure 10 wrinkles at the position corresponding to the first corner part of the display panel layer to crush the display panel layer or the display panel layer arches to be incapable of being attached normally can be prevented, and the stress concentration and the like of the quadric curved screen during attachment can be effectively relieved.
In addition, since the first metal layer 12 has the second corner portion 12b corresponding to the first corner portion, the second corner portion 12b can still support, cushion and dissipate heat of the first corner portion of the display panel layer, thereby effectively ensuring effective support and heat dissipation effects of the display panel layer.
It is understood that, considering the application of the under-screen support structure 10 to a quad-curved screen, the central support portion 12a of the first metal layer 12 may be a planar support portion, the second corner portions 12b may be curved portions, and the second corner portions 12b may be four, which may be located around the central support portion 12 a.
In some embodiments, as shown in fig. 7, in order to achieve the purpose that the elastic modulus of the second corner portion 12b is smaller than that of the central support portion 12a, a first notch 121 may be disposed at the position of the second corner portion 12b, as shown in fig. 7, fig. 7 is a schematic diagram of the second corner portion 12b provided with one first notch 121, and fig. 7 shows that the second corner portion 12b is four, and each second corner portion 12b is provided with one first notch 121. The first notch 121 is arranged to disconnect the curved surface at the position of the second corner portion 12b, so that on one hand, the elastic modulus of the second corner portion 12b is reduced, and the second corner portion 12b has certain deformation resistance, and meanwhile, the second corner portion 12b can be prevented from being arched or bulged due to stress concentration at the second corner portion 12b during fitting.
Further, since the under-screen support structure 10 is attached to the non-display side of the display panel layer, even if the first cutout 121 is provided at the second corner portion 12b, the display effect of the display panel layer is not affected.
Further, in a state where the second corner portion 12b is flattened, the depth direction S of the first notch 121 may be in a direction toward the center of the center support portion 12a along the edge of the second corner portion 12b, and the first notch 121 penetrates the edge of the second corner portion 12b, so that the curved surface on the second corner portion 12b may be cut off such that the curved surface is no longer continuous.
Further, the width direction of the first notch 121 may be a direction extending along the edge of the second corner portion 12b, and the width b of the first notch 121 cannot be too small in consideration of ensuring that the elastic modulus of the second corner portion 12b is smaller than that of the central support portion 12a, but at the same time, the support of the first corner portion of the display panel layer by the second corner portion 12b is also considered in consideration of, and therefore, the width b of the first notch 121 cannot be too large. Based on this, the following calculation procedure for the width b of the first notch 121 is briefly described as follows:
according to the simulation deformation and the appearance of the cover plate, the simulation modeling is compared with the actual experiment result, and the safety limit value of the stress of each film layer of the four-curved screen is preliminarily determined as shown in the table 1. In order to be able to adapt to the shape of the cover plate, the stress of each film layer of the quadric curved screen is lower than the safety value, otherwise the quadric curved screen is easy to lose efficacy.
TABLE 1
Therefore, in order not to cause a bulge, a camber, or the like at the time of bonding, the safety value of the deformation of the first metal layer 12 at the time of bonding should be not higher than 3.27%. Based on this, the inner bending radius R of the cover plate covering the display panel layer is taken as 3.5 mm. In the flattened state, the area of the cover plate in one of the corner regions may be approximately 1/4 circle areas, i.e., the area of the corner region is approximately π R2/4＝9.616mm2. The first metal layer 12 is formed at the corner region corresponding to the corner region due to the bending of the cover plateThe area compression of the location (i.e., the second corner portion 12b) cannot be greater than 9.616 × 3.27% — 0.314mm2. Based on the fact that when the first notch 121 is provided in the second corner portion 12b, the maximum opening width b of the first notch 121 (i.e., the edge penetrating the second corner portion 12b) should be within 0.18mm to 0.2mm, and if the opening width b is smaller than this range, the stress relief of the second corner portion 12b may be affected, and the elastic modulus of the second corner portion 12b may be larger and may not be enough to have a certain deformation margin, and if the opening width b is larger than this range, the elastic modulus of the second corner portion 12b may be too small, and thus the supporting and cushioning effect of the second corner portion 12b on the first corner portion of the display panel layer may be poor.
In some embodiments, as can be seen from the above calculated opening width b of the first incision 121, the calculation formula of the opening width b of the first incision 121 can be roughly as follows: l ═ R (pi R)23.27%) 2/R, the opening width of the first cut-out 121 is related to the outer shape of the cover plate, i.e. the opening width of the first cut-out 121 is related to the inner circle radius of the cover plate at the corner area. Therefore, when the inner circle radius of the cover plate at the corner area is larger, the opening width b of the first notch 121 may be correspondingly increased, or a plurality of first notches 121 may be provided, and the total opening width of the plurality of first notches 121 may be matched with the inner circle radius of the corner area of the cover plate.
In other words, the first notch 121 may be one or a plurality of notches, and when the first notch 121 is provided in plurality, the plurality of notches 121 should be spaced apart, and when the plurality of notches 121 are provided, the plurality of notches 121 should be sequentially spaced apart along the edge of the second corner portion 12b with the center of the curved surface of the second corner portion 12b as the center. For example, as shown in fig. 8, fig. 8 shows a scheme in which two first notches 121 are provided, and fig. 8 is a partial schematic view of the second corner portion 12 b.
Alternatively, the shape of the first notch 121 may include at least one of a rectangle, a trapezoid, a triangle, and a fan, as long as the curved surface on the second corner portion 12b can be broken and technically realized, and the shape of the first notch 121 is not particularly limited in this embodiment. For example, as shown in fig. 9, (b) in fig. 9 shows that the first slit 121 has a trapezoidal shape, and (a) in fig. 9 shows that the first slit 121 has a fan shape.
Illustratively, considering that the maximum width of the first slit 121 is 0.18mm to 0.2mm, the width of the first slit 121 is gradually reduced along the depth direction S of the first slit 121, and at this time, the shape of the first slit 121 may be at least one of a trapezoid, a triangle, or a fan.
In some embodiments, as shown in fig. 10, considering that the first metal layer 12 is a curved portion at the second corner portion 12b, the second corner portion 12b of the first metal layer 12 is deformed in a gradual manner at the time of bonding, i.e., gradually changes from both sides of the second corner portion 12b, i.e., from X, Y in fig. 10, therefore, an opening may be added to one side or both sides of the second corner portion 12b (as shown in fig. 10, fig. 10 is a partial view of the first metal layer 12 at the second corner portion 12b, fig. 10 shows that the opening 122 is provided at both sides of the first notch 122), that is, an opening 122 is further provided in the second corner portion 12b, the opening 122 being located at least on one side of the first notch 121, so that, the second corner portion 12b can be released in a gradual change manner when the deformation stress is released, so that the stress releasing effect on the second corner portion 12b is better.
Further, the diameter of the opening 122 may be smaller than or equal to the opening width of the first notch 121, so as to avoid a large influence on the strength of the second corner portion 12 b. The number of the openings 122 located on the same side of the first cut 121 may be one or more, and when there are a plurality of the openings 122, the openings 122 should be spaced apart from each other to avoid the situation that the structural strength of the second corner portion 12b is greatly affected due to the communication between two adjacent openings 122.
Taking the example that one side of the first notch 121 is provided with a plurality of openings 122, the plurality of openings 122 may be arranged at intervals along the depth direction S of the first notch 121. Considering that the second corner portion 12b of the first metal layer 12 is a curved surface portion, the deformation of the second corner portion 12b of the first metal layer 12 during the attaching process is gradual, i.e., the stress of the second corner portion 12b is concentrated at the edge, and the stress of the second corner portion 12b is gentle at the position close to the central support portion 12a, so that the arrangement density of the plurality of openings 122 is gradually reduced, and/or the diameters of the plurality of openings 122 are gradually reduced.
In an alternative example, as shown in fig. 10A, along the depth direction S of the first notch 121, when the aperture of the plurality of openings 122 is the same, the arrangement density of the plurality of openings 122 may gradually decrease, that is, the arrangement density of the openings 122 is larger near the edge of the second corner portion 12b, that is, the number of openings 122 is larger, and the arrangement density of the openings 122 is smaller near the central support portion 12a, that is, the number of openings 122 is smaller.
In another alternative example, as shown in fig. 10B, in the case where the arrangement density of the plurality of openings 122 is constant along the depth direction S of the first notch 121, the aperture diameters of the plurality of openings 122 may gradually decrease. That is, the aperture of the opening 122 is larger at a position near the edge of the second corner portion 12b, and the aperture of the opening 122 is smaller at a position near the central support portion 12 a.
In still another alternative example, as shown in fig. 10C, along the depth direction S of the first notch 121, the arrangement density of the plurality of openings 122 is gradually reduced, and at the same time, the aperture diameters of the plurality of openings 122 are gradually reduced. That is, the arrangement number of the openings 122 is larger while the aperture of the openings 122 is larger at a position near the edge of the second corner portion 12b, and the arrangement number of the openings 122 is smaller while the aperture of the openings 122 is smaller at a position near the central support portion 12 a.
In some embodiments, the entire first metal layer 12 may be a copper foil layer, that is, the material of the central supporting portion 12a and the second corner portion 12b are both copper foils, so that the first metal layer 12 not only can have sufficient structural strength to support the display panel layer, but also the first metal layer 12 can have good heat dissipation performance, which can ensure the heat dissipation effect on the display panel layer. Alternatively, the first metal layer 12 may be an aluminum foil layer as a whole, the heat dissipation performance of the aluminum foil layer is good, and the elastic modulus of the aluminum foil is smaller than that of the copper foil, so that when the first metal layer 12 is an aluminum foil layer as a whole, the deformation resistance is better than that when the first metal layer 12 is a copper foil layer as a whole.
It should be noted that, since the structural strength of the aluminum foil layer is weaker than that of the copper foil layer, the supporting effect on the display panel layer is weaker than that of the copper foil layer.
In other embodiments, as shown in fig. 11, the first metal layer 12 is a split structure, that is, the material of the central supporting portion 12a of the first metal layer 12 is different from the material of the second corner portion 12b, and in this case, the second corner portion 12b may be welded or bonded to the central supporting portion 12 a. For example, the central supporting portion 12a of the first metal layer 12 may be a copper foil layer, and the second corner portion 12b may be an aluminum foil layer. Since the elastic modulus of the aluminum foil is smaller than that of the copper foil, in this manner, the second corner portion 12b may be provided with the first notch 121 (for example, as shown in fig. 11, fig. 11 shows that the copper foil is used for the central support portion 12a, and the aluminum foil is used for the second corner portion 12b, that is, the aluminum foil is used for the area shown by the dotted line in fig. 11, and the first notch 121 is provided for the second corner portion 12 b).
Of course, when the central support portion 12a is made of copper foil and the second corner portion 12b is made of aluminum foil, the elastic modulus of the aluminum foil is smaller than that of the copper foil, and therefore, the first notch 121 may not be provided in the second corner portion 12b (for example, as shown in fig. 12, that is, fig. 12 shows that the central support portion 12a is made of copper foil and the second corner portion 12b is made of aluminum foil, wherein the second corner portion 12b is shown by a dotted line).
In other embodiments, the entire material of the first metal layer 12 is copper foil, but at the same time, the under-screen support structure 10 may further include a second metal layer (not shown), which may be disposed at least at a position of the second corner portion 12b corresponding to the first notch 121, and has an elastic modulus smaller than that of the first metal layer 12. That is, the material of the second metal layer may be an aluminum foil, and the second metal layer 13 may be attached to the second corner portion 12b at a position corresponding to the first notch 121.
As can be seen, the second corner portion 12b can have a certain deformation resistance as long as the elastic modulus of the second corner portion 12b is smaller than that of the center support portion 12a, so that the risk of the first corner portion being wrinkled due to arching when the second corner portion 12b is bonded to the first corner portion of the display panel layer can be reduced, and the material of the second corner portion 12b and the center support portion 12a is not particularly limited in this embodiment.
Referring to fig. 13, fig. 13 is a partial schematic view of the buffer layer 11 at a position corresponding to the second corner portion 12 b. In some embodiments, in order to further ensure that the under-screen support structure 10 can have a certain deformation amount at the position corresponding to the first corner of the display panel layer, a notch may be provided at the position of the buffer layer 11 corresponding to the second corner 12b, that is, a second notch 111 may be provided at the position of the buffer layer 11 corresponding to the second corner 12 b. The second notch 111 is used to reduce the stress concentration of the buffer layer 11 at the position corresponding to the second corner portion 12b, and the depth, shape, opening width, etc. of the second notch 111 can refer to the depth, shape, opening width, etc. of the first notch 121 disposed on the second corner portion 12b, and will not be described herein again.
Further, since the buffer layer 11 mainly serves to buffer the display panel layer when an external force is applied to the display panel or when the display panel is dropped, the elastic modulus of the buffer layer 11 may be smaller than that of the second corner portion 12b, and thus, the buffer layer 11 may be a foam layer or a Thermoplastic polyurethane elastomer (TPU) layer. Because under the same thickness, the elasticity performance of thermoplastic polyurethane elastic rubber layer is better than in the foam, therefore, the thickness when this buffer layer 11 is thermoplastic polyurethane elastic rubber layer can be less than the thickness when buffer layer 11 is the foam layer, and like this, this under screen support structure 10's whole thickness is littleer to can effectively reduce this under screen support structure 10's whole modulus of elasticity.
Optionally, the buffer layer 11 has a thickness in the range of 0.04mm to 0.11 mm. Illustratively, the thickness of the buffer layer 11 may be 0.04mm, 0.05mm, 0.07mm, 0.08mm, 0.09mm, 0.10mm, 0.11mm, or the like.
For example, when the cushioning layer 11 is a foam layer, the thickness of the cushioning layer 11 may be 0.1mm, and when the cushioning layer 11 is a thermoplastic polyurethane elastic rubber layer, the thickness of the cushioning layer 11 may be 0.05 mm. It is to be understood that the above thickness is merely an example for convenience of understanding, as long as the thickness when the cushioning layer 11 is a thermoplastic polyurethane elastic rubber layer can be smaller than the thickness when the cushioning layer 11 is a foam layer, and this embodiment is not particularly limited thereto.
In some embodiments, the under-screen support structure 10 may further include a heat conducting layer 14, the heat conducting layer 14 may be disposed between the buffer layer 11 and the metal layer, and the heat conducting layer 14 is mainly used for conducting and dissipating heat of the display panel layer to improve the heat dissipation effect of the display panel layer. Specifically, the heat conducting layer 14 may be a graphite layer, specifically, the heat conducting layer 14 may include a substrate and graphite formed on the substrate, and the heat conducting and dissipating effects of the graphite are better, so that the heat conducting and dissipating effects of the display panel layer can be effectively ensured.
Alternatively, the substrate may be a PET (Polyethylene terephthalate) substrate or PVC (Polyvinyl chloride) or the like.
It will be appreciated that the under-screen support structure 10 may have roughly two configurations, considering that the addition of the heat conductive layer 14 affects the overall thickness of the under-screen support structure 10, and in particular, the heat conductive layer 14 has graphite, which has a large elastic modulus, and thus affects the elastic modulus of the under-screen support structure 10:
as shown in fig. 14, fig. 14 is a schematic view of a stacked structure of the under-screen support structure 10, and the first structure: the under-screen support structure 10 includes a buffer layer 11, a heat conducting layer 14 and a first metal layer 12 sequentially arranged from top to bottom.
The second structure is as follows: the under-screen support structure 10 includes a buffer layer 11 and a first metal layer 12 arranged in this order from top to bottom, i.e., in the second configuration, the heat conductive layer 14 may not be provided. That is, in this structure, the heat conductive layer 14 is not disposed between the buffer layer 11 and the first metal layer 12, so that the elastic modulus of the under-screen support structure 10 can be effectively reduced, thereby facilitating the deformation resistance of the under-screen support structure 10.
As shown in fig. 15, fig. 15 is a partial schematic view of the heat conductive layer 14 at a position corresponding to the second corner 12b, in some embodiments, when the under-screen support structure 10 further includes the heat conductive layer 14, a third notch 141 may be formed at a position corresponding to the second corner 12b of the heat conductive layer 14, the third notch 141 is used to reduce stress concentration at a position corresponding to the second corner 12b of the heat conductive layer 14, and the depth, shape, opening width, and the like of the third notch 141 may refer to the depth, shape, opening width, and the like of the first notch 121 formed at the second corner 12b, and will not be described herein again.
In some embodiments, the under-screen support structure 10 may further include a protective film layer 15, the protective film layer 15 may be disposed on a side of the buffer layer 11 facing away from the first metal layer 12, and the protective film layer 15 may be used to protect the buffer layer 11. Specifically, the protective film layer 15 may be a release film layer, so that the buffer layer 11 may be prevented from being contaminated by dust and impurities during the rotation of the under-screen support structure 10, and when the under-screen support structure 10 is attached to the four-curved screen, the buffer layer 10 may be exposed by peeling off the protective film layer 15, so that the buffer layer 10 may be connected to the display panel layer of the four-curved screen.
The under-screen support structure 10 disclosed in the embodiment of the present application, by providing the first notch 121 on the second corner portion 12b of the first metal layer 12, and/or by providing the second corner portion 12b made of an aluminum foil and the center support portion 12a made of a copper foil, the elastic modulus of the first metal layer 12 on the second corner portion 12b is smaller than that of the center support portion 12a, so that when the under-screen support structure 10 is attached to the display panel layer of the quad flat screen, the under-screen support structure 10 can be prevented from wrinkling at the position corresponding to the first corner portion of the display panel layer to crush the display panel layer, or the display panel layer is prevented from arching and cannot be normally attached, and the stress concentration situation of the quad flat screen during attachment is effectively alleviated.
In addition, when the first notch 121 is provided at the second corner portion 12b, since the under-screen support structure 10 is attached to the non-display side of the display panel layer, the provision of the first notch 121 does not affect the display of the display panel layer, thereby ensuring the display effect of the display panel layer.
Referring to fig. 16 and 17 together, fig. 16 is a schematic diagram of a stacked structure of a quad flat panel 20 disclosed in an embodiment of the present application, fig. 17 is a schematic diagram of a structure of the quad flat panel 20 disclosed in the embodiment of the present application, and in a second aspect, the present application further discloses a quad flat panel 20, the quad flat panel 20 may include a display panel layer 21 and an under-screen support structure 10 as described in the first aspect, the display panel layer 21 includes a central display portion 210 and a first corner portion 211 connected to the central display portion 210, the buffer layer 11 may be connected to one side of the display panel layer 21, the central support portion 12a of the first metal layer 12 is disposed corresponding to the central display portion 210, and the second corner portion 12b of the first metal layer 12 is disposed corresponding to the first corner portion 211.

It can be seen that when the under-screen support structure 10 is attached to the display panel layer 21, since the second corner portion 12b of the first metal layer 12 is disposed corresponding to the first corner portion 211 of the display panel layer 21, when the first notch 121 is opened in the second corner portion 12b, the first sub-curved surface portion 213a and the second sub-curved surface portion 213b are disconnected at the connection position corresponding to the first notch 121, so that the stress can be released at this position.
