All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the invention.
As shown in fig. 1, the display panel includes a display layer 3, an adhesive layer 2, and a functional film layer 1. The display layer 3 is used for emitting display light, wherein the adhesive layer 2 is arranged on one side of the light emitting direction of the display layer 3, and the light emitting direction refers to the propagation direction of the display light emitted by the display layer 3. The function film layer 1 is arranged on one side of the adhesive layer 2 far away from the display layer 3, and the function of the adhesive layer 2 is to adhere the function film layer 1 to the display layer 3. The functional film layer 1 may be a film layer structure capable of realizing a certain function, for example, the functional film layer 1 may be a touch layer. The display layer 3 may include at least one bending region and at least one non-bending region, and the bending region may include a bending axis. The adhesive layer 2 comprises at least one arc-shaped structure, the projection of the arc-shaped structure on the display layer 3 is positioned in a bending area, in other words, the adhesive layer 2 corresponding to the bending area of the display layer 3 is set to be arc-shaped, and as the functional film layer 1 is flexible, a certain radian can be guaranteed to appear when the functional film layer 1 is attached to the arc-shaped structure of the adhesive layer 2, and the radian corresponds to the bending area of the display layer 3, so that the functional film layer 1 has a certain radian before bending, when the display panel is bent again, the functional film layer 1 bends on the original radian, compared with the direct bending, the bending angle can be reduced, the stress born by the deformation amount and the film layer is reduced, and the film layer separation phenomenon is reduced.

It is also understood that the functional film layer 1 may have a single-layer structure or a multi-layer structure. When the functional film layer 1 has a single-layer structure, for example, the functional film layer 1 may be a touch layer, or may be a polarizing layer 31; when the functional film layer 1 is a multilayer structure, for example, the functional film layer 1 may be a combination of the touch layer and the polarizing layer 31, or a combination of film layers having other functions. Whether the functional film layer 1 is of a single-layer structure or a multi-layer structure may be set according to the actual product, and the present invention is not limited to whether the functional film layer 1 is of a single-layer structure or a multi-layer structure.
In an embodiment of the present invention, the display panel may be a display panel with a fixed bending angle and direction, for example, the display panel may be a bending away from the light emitting direction or the display panel may be a bending towards the light emitting direction. When the display panel is bent away from the light emitting direction, the arc of the arc structure faces the display panel, and when the display panel is bent towards the light emitting direction, the arc of the arc structure faces away from the display panel, in other words, the arc of the arc structure of the functional film layer 1 and the arc of the bending direction of the display panel are in the same direction. Therefore, the functional film layer 1 can be guaranteed to have a certain radian before bending, and when the display panel is bent again, the functional film layer 1 bends on the original radian, compared with the direct bending, the bending angle can be reduced, the deformation amount and the stress born by the film layer are reduced, and therefore the separation phenomenon between the film layers is reduced.

As shown in fig. 3, when the adhesive layer 2 has a multi-layer structure, the adhesive layer 2 may include a plurality of sub-adhesive layers 2, and the plurality of sub-adhesive layers 2 are sequentially stacked along the light emitting direction. Therefore, when the plurality of sub-adhesive layers 2 are sequentially stacked along the light emitting direction, the portions of the plurality of sub-adhesive layers 2 corresponding to the bending regions are arranged in a step shape, in other words, on the cross section perpendicular to the direction of the bending axis of the display layer 3, the lengths of the plurality of sub-adhesive layers 2 decrease or increase sequentially along the light emitting direction, so that the portions of the plurality of sub-adhesive layers 2 corresponding to the bending regions are arranged in a step shape to form an arc structure. When the display panel is a bent display panel deviating from the light emitting direction, the radian of the arc-shaped structure faces the display panel, and on the cross section perpendicular to the bending axis of the display layer 3, the lengths of the plurality of sub adhesive layers 2 are sequentially decreased along the light emitting direction to form an arc-shaped structure facing the display panel; when the display panel is a display panel which is bent towards the light emitting direction, the radian of the arc-shaped structure is deviated from the display panel, and the lengths of the plurality of sub-adhesive layers 2 are sequentially increased along the light emitting direction on the cross section perpendicular to the direction of the bending axis of the display layer 3 so as to form the arc-shaped structure deviated from the display panel. The plurality of sub adhesive layers 2 are arranged in a lamination manner along the light emitting direction to form a stepped arrangement to form an arc-shaped structure, so that the process is simple, the additional cost is not increased, and the realization is easy.
It can be understood that the adhesive layer 2 may be a single-layer structure or a multi-layer structure, and the specific structure of the adhesive layer 2 may be any structure, and how the arc-shaped structure is formed may be selected according to practical situations, and the specific structure of the adhesive layer 2 is not limited in the present invention.
It can be further understood that when the number of the adhesive layers 2 is plural, on the cross section perpendicular to the bending axis of the display layer 3, the lengths of the plural sub-adhesive layers 2 may be sequentially decreased along the light emitting direction or sequentially increased, and how the lengths of the plural sub-adhesive layers 2 are changed along the light emitting direction is set according to the requirement of the actual product.
In an embodiment of the present invention, the projection of the arc structure on the display layer 3 is completely coincident with the bending region. In other words, the projection of the starting position of the arc structure on the display layer 3 coincides with the starting edge of the bending region of the display layer 3, and the projection of the ending edge of the arc structure on the display layer 3 coincides with the ending edge of the bending region of the display layer 3. The projection of the arc-shaped structure of the functional film layer 1 on the display layer 3 is completely overlapped with the bending area, so that the functional film layer 1 corresponding to the bending area can be guaranteed to have a certain radian, when the display panel is bent again, the functional film layer 1 is bent on the original radian, compared with the direct bending, the bending angle can be reduced, the deformation amount and the stress borne by the film layer are reduced, and the separation phenomenon between the film layers is reduced.
It can be understood that the radian of the arc structure is determined according to the bending radian of the display panel, and the structure can meet the bending limit angle of the display panel, and the bending radius of the display panel is generally about 5mm at present, which requires that the radian of the arc structure is less than 5mm. However, on the premise that the phenomenon of separation between film layers can be reduced after the display panel is bent, the specific radian of the arc-shaped structure can be selected, and the specific radian of the arc-shaped region is not limited.
Fig. 4 is a schematic structural diagram of a display panel according to another embodiment of the invention.
As shown in fig. 4, the functional film layer 1 may be a touch layer, the display layer 3 may further include a polarizing layer 31 disposed on a side of the adhesive layer away from the touch layer, the polarizing layer 31 may be a polarizer, which is a lens capable of passing light vibrating in a specific direction but not passing light in other vibration directions (or having a very small passing rate), and the single polarizer is transparent as compared with a common glass lens, but when the two polarizers are vertically stacked together according to their polarization directions, the two polarizers are found to become opaque, and the polarizer may be mainly used for liquid crystal display imaging. In a cross section perpendicular to the bending axis of the display layer 3, the width of the touch layer is larger than the width of the polarizing layer 31. On the cross section of the direction of the bending axis perpendicular to display layer 3, set the width of touch control layer to be greater than the width of polarizing layer 31, prevent that function rete 1 laminating from appearing buckling on viscose layer 2 after, function rete 1 can not cover the problem on display rete completely and produce, and on the cross section of the direction of the bending axis perpendicular to display layer 3, set the width of touch control layer to be greater than the width of polarizing layer 31, can make function rete 1 the relative deflection volume when buckling smaller, thereby make function rete 1 the stress that bears when buckling lower, make the phenomenon of rete layering appear more difficult to between function rete 1 and the display layer, also can reduce the problem that function rete 1 takes place the fracture when buckling.
It is further understood that the display layer may further include a substrate, an array layer, a light emitting layer, an encapsulation layer, and the like, which are sequentially stacked, wherein the encapsulation layer is disposed at an end of the polarizing layer away from the adhesive layer. The display layer may include other functional film layers in addition to the substrate, the array layer, the light emitting layer, and the encapsulation layer, or the display layer may not include one or more of the substrate, the array layer, the light emitting layer, and the encapsulation layer. The display layer comprises what kind of functional film layer is set according to actual product requirements, and the invention does not limit what kind of functional film layer comprises.
In an embodiment of the present invention, the projection of the functional film layer 1 on the display layer 3 coincides with the display layer 3, in other words, the peripheral edge of the functional film layer 1 is flush with the display layer 3. In a cross section perpendicular to the bending axis of the display layer 3, the end edge of the functional layer is in line with the end edge of the display layer 3. The peripheral edges of the functional film layer 1 are arranged to be flush with the display layer 3, so that the phenomenon that the edge angle of the display panel appears to influence the user experience when a user uses the display panel because the functional film layer 1 is attached to the adhesive layer 2 and bent, and the ending edge of the functional layer is not in a straight line with the ending edge of the display layer 3 on the cross section perpendicular to the direction of the bending axis of the display layer 3 can be prevented.
It can be understood that the peripheral edge of the functional film layer 1 may be flush with the display layer 3, or the functional film layer 1 is completely wrapped around the display layer 3, or the functional film layer 1 and the display layer 3 may also have other structural arrangements, etc., and the structural relationship between the functional film layer 1 and the display layer 3 may be adjusted and selected according to the product requirement.
In an embodiment of the present invention, the terminal device includes the display panel according to any one of the above embodiments, wherein the display panel includes a display layer 3, an adhesive layer 2, and a functional film layer 1. The display layer 3 may emit display light, wherein the adhesive layer 2 is disposed at one side of the light emitting direction of the display layer 3, which refers to the propagation direction of the display light emitted from the display layer 3. The functional film layer 1 is arranged on one side, far away from the display layer 3, of the adhesive layer 2, and the functional film layer 1 is adhered to the display layer 3 by the adhesive layer 2, wherein the functional film layer 1 can be a film layer structure capable of realizing a certain function, for example, the functional film layer 1 can be a touch control layer. Wherein the display layer 3 may comprise a bending region and a non-bending region, and the bending region may comprise a bending axis. The viscose layer 2 includes at least one arc structure, the projection of an arc structure on the display layer 3 is located a district of buckling, will correspond the viscose layer 2 of the district of buckling of display layer 3 and set up the arc structure, because function membrane layer 1 is flexible, can guarantee like this that function membrane layer 1 pastes and appear certain radian on viscose layer 2, and this radian corresponds the district of buckling of display layer 3, can make function membrane layer 1 just exist certain radian before buckling like this, when display panel buckles again, function membrane layer 1 buckles on original radian, compare in direct buckling can reduce the angle of buckling, reduce the stress that deflection and rete received, thereby reduce the phenomenon of rete separation.
