Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
In the related art, the thicknesses of the film materials used in the curved-surface display panel at all positions are consistent, so that when the film materials are bent and attached to a structure to be attached, the film materials at the bent area are large in rebound force due to small moment, and the film materials at the bent area are not tightly attached to the structure to be attached, and the phenomenon of glue failure occurs.
Therefore, the embodiment of the invention processes the film material body at the to-be-bent area to form the plurality of grooves, so that the thickness of the film material body at the area where the grooves are located is reduced, and the rebound force of the film material body at the to-be-bent area is reduced, therefore, when the film material body at the to-be-bent area is bent and attached to the to-be-attached structure, the film material body at the bent area can be attached to the to-be-attached structure more tightly, and the phenomenon of glue failure is avoided.
Example one
Referring to fig. 1, a plan view of a film according to an embodiment of the present invention is shown, and fig. 2 is a cross-sectional view of the film shown in fig. 1 taken along a section a-a'.
The embodiment of the invention provides a membrane material, which comprises: the film material comprises a film material body 11, wherein the film material body 11 is provided with a plane area 111 and an area to be bent 112; the film material body 11 located in the region 112 to be bent has a plurality of grooves 10, and the depth h1 of the grooves 10 is smaller than the thickness h2 of the film material body 11 located in the planar region 111.
Specifically, the film provided by the embodiment of the invention is applied to a curved display panel, and the film includes a film body 11, and the film body 11 has a planar region 111 and a region 112 to be bent. The planar region 111 refers to a region where the film material body 11 does not need to be bent when the film material body 11 is attached to the structure to be attached, and after the film material body 11 at the planar region 111 is attached to the structure to be attached, at the planar region 111, both a surface of the structure to be attached, which is in contact with the film material body 11, and a surface of the film material body 11, which is in contact with the structure to be attached, are planar; the region 112 to be bent refers to a region where the film material body 11 needs to be bent when the film material body 11 is attached to the structure to be attached, and after the film material body 11 at the region 112 to be bent is bent and attached to the structure to be attached, at the region 112 to be bent, the surface of the structure to be attached in contact with the film material body 11 and the surface of the film material body 11 in contact with the structure to be attached are both curved surfaces, for example, the surface of the structure to be attached in contact with the film material body 11 and the surface of the film material body 11 in contact with the structure to be attached are both curved surfaces.
In actual products, the structures to be attached often have two side edge regions that need to be designed to be curved, and therefore, in order to better attach the structures to be attached to the film material body 11, the regions to be bent 112 are disposed on two sides of the planar region 111, that is, the film material body 11 has two regions to be bent 112 and the planar region 111 located between the two regions to be bent 112.
In addition, in order to more closely attach the film material body 11 to the structure to be attached, the film material body 11 at the region 112 to be bent needs to be cut to form a plurality of grooves 10, so that the thickness of the film material body 11 at the region where the grooves 10 are located is reduced, and the thickness of the film material body 11 at the region where the non-grooves are located in the region 112 to be bent is equal to the thickness h2 of the film material body 11 at the planar region 111.
When the thickness of the film material body 11 at the region where the groove 10 is located is reduced, the rebound force of the film material body 11 at the region 112 to be bent is correspondingly reduced, and when the film material body 11 at the region 112 to be bent is subsequently bent and attached to the structure to be attached, the film material body 11 at the bent region (i.e., the region where the film material body 11 at the region 112 to be bent is bent) can be attached to the structure to be attached more tightly, so that the phenomenon of glue failure is avoided. And, when not having the time of opening glue between membrane material body 11 and the structure of waiting to laminate, the foreign matter is also difficult to get into curved surface display panel inside from the position of opening glue to curved surface display panel's performance can be improved.
In an actual product, the groove 10 does not penetrate through the film body 11 in the thickness direction of the film body 11, that is, the depth h1 of the groove 10 is smaller than the thickness h2 of the film body 11 in the plane area 111; the grooves 10 are distributed along a first direction of the region to be bent 112, and the length of the grooves 10 along the first direction is equal to the length of the region to be bent 112 along the first direction, the first direction is perpendicular to a second direction, and the first direction and the second direction are both parallel to the plane of the film material body 11, and the second direction refers to the direction of the region to be bent 112 towards the plane region 111.
It should be noted that the number of the grooves 10 of the film body 11 at the region 112 to be bent and the distance between two adjacent grooves 10 are determined according to the width of the region 112 to be bent along the second direction, which is not limited in the embodiment of the present invention; in addition, the depth h1 of each groove 10 may be equal or unequal; the depth of the groove 10 is the thickness of the film body 11, that is, the groove 10 faces the thickness of the film body 11 in the embodiment of the present invention.
Specifically, the ratio of the depth h1 of the groove 10 to the thickness h2 of the film body 11 located in the planar region 111 is 0.2 to 0.8, for example, the ratio of the depth h1 of the groove 10 to the thickness h2 of the film body 11 at the planar region 111 is 0.3, 0.5, 0.6, and the like.
When the film is a cover plate, the thickness h2 of the film body 11 in the planar region 111 is 50 μm to 200 μm. For example, when the thickness h2 of the film body 11 located in the planar region 111 is 100 μm, the depth h1 of the groove 10 may be set to 50 μm, and at this time, the thickness of the film body 11 at the region where the groove 10 is located is also 50 μm.
The material of the film body 11 may be any flexible material having excellent mechanical properties, bending resistance, and no crease, and the specific material of the film body 11 is not limited in the embodiments of the present invention.
Further, as shown in fig. 3 and 4, the film further includes a light shielding layer 12, and the light shielding layer 12 at least covers the film body 11 located in the region to be bent 112.
As shown in fig. 3, the light shielding layer 12 covers only the film material body 11 at the region to be bent 112, and at this time, the light shielding layer 12 is provided only at the region to be bent 112 of the film material body 11, and the area of the light shielding layer 12 is equal to the area of the region to be bent 112.
As shown in fig. 4, the light shielding layer 12 not only covers the film material body 11 at the region to be bent 112, but also partially covers the film material body 11 at the planar region 111, in this case, the light shielding layer 12 is disposed at both the region to be bent 112 and a portion of the planar region 111 of the film material body 11, and the area of the light shielding layer 12 is larger than that of the region to be bent 112. For example, if the width of the light shielding layer 12 beyond the region to be bent 112 and disposed in the planar region 111 is d1, and the length of the film body 11 is L1, the difference between the area of the light shielding layer 12 and the area of the region to be bent 112 is d1 × L1, and the specific size of the width d1 of the light shielding layer 12 disposed in the planar region 111 needs to be set according to the actual product, which is not limited in the embodiment of the present invention.
By adding the light shielding layer 12 in the film material, and the light shielding layer 12 at least covers the film material body 11 located in the region 112 to be bent, therefore, the cutting traces of each groove 10 at the region 112 to be bent can be shielded by the light shielding layer 12, so that the cutting traces can not be seen by the eyes of a user, and the appearance of the curved display panel manufactured by using the film material is improved.
In the embodiment of the present invention, as shown in fig. 3 and 4, the film body 11 includes a first surface 113 and a second surface 114 that are oppositely disposed, and the light shielding layer 12 is located on the first surface 113 or the second surface 114.
In an actual product, at least one of the first surface 113 and the second surface 114 of the film material body 11 needs to be attached to a structure to be attached, when only one surface of the film material body 11 needs to be attached to the structure to be attached, the surface attached to the structure to be attached is referred to as a first surface 113, the surface not attached to the structure to be attached is referred to as a second surface 114, and the first surface 113 and the second surface 114 are oppositely arranged, at this time, the groove 10 is located on one side of the first surface 113; when the two surfaces of the film material body 11 need to be respectively attached to different structures to be attached, the surface away from the light-emitting side of the curved display panel is referred to as a first surface 113, the surface facing the light-emitting side of the curved display panel is referred to as a second surface 114, the first surface 113 and the second surface 114 are oppositely arranged, and at the moment, the groove 10 is formed in one side where the first surface 113 is located and one side where the second surface 114 is located.
As shown in fig. 3, the light shielding layer 12 may be located on the first surface 113 of the film material body 11, and as shown in fig. 4, the light shielding layer 12 may also be located on the second surface 114 of the film material body 11.
In addition, when the thickness of the film material body 11 at the region where the groove 10 in the region 112 to be bent is located is reduced, the film material body 11 of the first surface 113 may be cut to form the groove 10 located at the side where the first surface 113 is located, or both the film material body 11 of the first surface 113 and the film material body 11 of the second surface 114 may be cut to form the groove 10 located at the side where the first surface 113 is located and the groove 10 located at the side where the second surface 114 is located.
As shown in fig. 2 to 4, if only the film body 11 on the first surface 113 is cut to reduce the thickness of the film body 11 at the region where the groove 10 is located in the region 112 to be bent, the first surface 113 of the film body 11 at the region where the groove 10 is located in the region 112 to be bent may not be in the same plane as the first surface 113 of the film body 11 at the planar region 111, namely, the first surface 113 of the film material body 11 at the area where the groove 10 is located in the region 112 to be bent has a certain level difference with the first surface 113 of the film material body 11 at the planar region 111, the first surface 113 of the film body 11 at the non-groove region in the region 112 to be bent and the first surface 113 of the film body 11 at the planar region 111 are located on the same plane, and the second surface 114 of the film body 11 at the region 112 to be bent and the second surface 114 of the film body 11 at the planar region 111 are also located on the same plane.
If the thickness of the film material body 11 at the region where the groove 10 is located in the region 112 to be bent is reduced by cutting the film material body 11 at the second surface 114 as well as cutting the film material body 11 at the first surface 113, the first surface 113 of the film material body 11 at the region where the groove 10 is located in the region 112 to be bent and the first surface 113 of the film material body 11 at the planar region 111 are not in the same plane, and the second surface 114 of the film material body 11 at the region where the groove 10 is located in the region 112 to be bent and the second surface 114 of the film material body 11 at the planar region 111 are not in the same plane, while the first surface 113 of the film material body 11 at the region where the non-groove is located in the region 112 to be bent and the first surface 113 of the film material body 11 at the planar region 111 are in the same plane, and the second surface 114 of the film material body 11 at the region where the non-groove is located in the region 112 to be bent and the second surface 114 of the film material body 11 at the planar region 111 are also in the same plane.
In the embodiment of the present invention, the material of the light shielding layer 12 is black ink. In addition, the material of the light shielding layer 12 may also be other light shielding materials, such as light shielding glue.
The light shielding layer 12 is made of black ink, and the black ink is opaque and has certain adhesiveness, so that the light shielding layer 12 can shield cutting traces of the grooves 10 in the bending region 112, the adhesive force between the film material body 11 and the structure to be attached is improved, and the attaching tightness between the film material body 11 in the bending region and the structure to be attached is further improved.
As shown in fig. 5, after the film body 11 at the region 112 to be bent is cut to form a plurality of grooves 10, the thickness of the film body 11 at the region where the grooves 10 are located is reduced by 10mm compared with the thickness of the film body 11 before cutting, then the film body 11 at the region 112 to be bent is bent, and a pressure plate is used to apply pressure to the film body 11 at the region 112 to be bent, so as to obtain a curve chart shown as 51 in fig. 5; thinning the film material body 11 at the area where the groove 10 in the area 112 to be bent is located by 10mm, coating black ink on the area 112 to be bent of the film material body 11, bending the film material body 11 at the area 112 to be bent, and applying pressure to the film material body 11 at the area 112 to be bent by using a pressing plate to obtain a curve chart shown as 52 in fig. 5; after bending the existing film body, a pressure plate is used to apply pressure to the film body in the existing region to be bent, and a curve diagram shown as 53 in fig. 5 is obtained.
In fig. 5, the abscissa represents the distance in mm between the pressing plate and the film body when the pressing plate is used to apply pressure to the film body at the region to be bent, and the ordinate represents the repulsive force of the film body in N.
Through experimental determination, if only the film material body 11 at the region to be bent 112 is cut, the bounce of the cut film material body 11 can be reduced by 87.16% compared with the bounce of the existing film material body, and if the film material body 11 at the region to be bent 112 is cut and the cut film material body 11 is coated with black ink, the bounce is reduced by 23.67% compared with the bounce of the existing film material body. Therefore, in the embodiment of the present invention, the film body 11 at the region to be bent 112 is cut to form the plurality of grooves 10, so that the thickness of the film body 11 at the region where the grooves 10 are located is reduced, and the bounce of the film body 11 at the region to be bent 112 can be obviously reduced.
In the embodiment of the invention, as shown in fig. 3, the light shielding layer 12 is located on the first surface 113, and the thickness h3 of the light shielding layer 12 at the region where the groove 10 is located is greater than or equal to the depth h1 of the groove 10.
If only the film material body 11 of the first surface 113 is cut and the light shielding layer 12 is located on the first surface 113 of the film material body 11, if the thickness h3 of the light shielding layer 12 at the region where the groove 10 in the region 112 to be bent is equal to the depth h1 of the groove 10, the surface of the light shielding layer 12 and the first surface 113 of the film material body 11 at the planar region 111 are located on the same plane.
If only the film material body 11 of the first surface 113 is cut and the light shielding layer 12 is located on the first surface 113 of the film material body 11, if the thickness h3 of the light shielding layer 12 at the region where the groove 10 in the region 112 to be bent is greater than the depth h1 of the groove 10, the surface of the light shielding layer 12 is not on the same plane as the first surface 113 of the film material body 11 at the planar region 111.
Specifically, when the thickness h3 of the light-shielding layer 12 in the region where the groove 10 is located in the region 112 to be bent is larger than the depth h1 of the groove, the difference between the thickness h3 and the depth h1 of the groove 10 is less than or equal to 10 μm.
When the light-shielding layer 12 is located on the second surface 114 of the film body 11, the thickness h3 of the light-shielding layer 12 may be greater than the depth h1 of the groove 10, or smaller than the depth h1 of the groove 10.
In the embodiment of the invention, the film body at the to-be-bent area is processed to form the plurality of grooves, so that the thickness of the film body at the area where the grooves are located is reduced, and the rebound force of the film body at the to-be-bent area is reduced, therefore, when the film body at the to-be-bent area is bent and attached to the to-be-attached structure, the film body at the bent area can be attached to the to-be-attached structure more tightly, the phenomenon of adhesive separation is avoided, and the performance of the curved-surface display panel can be improved.
Example two
Referring to fig. 6, a flowchart of a manufacturing method of a film according to an embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, first, a film body 11 is provided, where the film body 11 has a planar region 111 and a region 112 to be bent, and at this time, the thicknesses of the film body 11 at the planar region 111 and the region 112 to be bent are consistent.
In the embodiment of the present invention, after obtaining the film material body 11 with the same thickness of the film material body 11 at the planar region 111 and the region to be bent 112, the film material body 11 located at the region to be bent 112 is cut to form the plurality of grooves 10, so that the thickness of the film material body 11 at the region where the groove 10 is located in the region to be bent 112 is reduced.
Specifically, the film material body 11 at the to-be-bent area 112 is cut by adopting a laser cutting process, the cutting process has strong operability, and the film material body 11 at the to-be-bent area 112 can be thinned well.
In the actual manufacturing process, only the film body 11 of the first surface 113 may be cut, or both the film body 11 of the first surface 113 and the film body 11 of the second surface 114 may be cut.
According to the above-described manufacturing method, the film material shown in fig. 1 and 2 can be manufactured, and in this case, the film material includes only the film material body 11.
After the film body 11 is manufactured, a light shielding layer 12 may be formed on the first surface 113 or the second surface 114 of the film body 11, and the light shielding layer 12 at least covers the film body 11 located in the region 112 to be bent. Specifically, the light shielding layer 12 may be formed on the first surface 113 or the second surface 114 of the film body 11 using a coating process or a printing process.
In the embodiment of the invention, the film body at the to-be-bent area is processed to form the plurality of grooves, so that the thickness of the film body at the area where the grooves are located is reduced, and the rebound force of the film body at the to-be-bent area is reduced, therefore, when the film body at the to-be-bent area is bent and attached to the to-be-attached structure, the film body at the bent area can be attached to the to-be-attached structure more tightly, the phenomenon of adhesive separation is avoided, and the performance of the curved-surface display panel can be improved.

When the film material is a cover plate, the film material body 11 may cover the cover plate body, the to-be-bonded structure bonded to the cover plate body is a to-be-bonded panel 20 having a polarizer 30, and the cover plate body and the light shielding layer 12 are bonded to the polarizer 30 through the optical cement 40.
In an actual product, the cover plate in the curved display panel may be one layer or multiple layers.
