Technical Field

Background
With the continuous development of display products, the display size of the display device is also larger and larger, and the display effect is also continuously improved. However, as the size of the display increases, some difficulty is caused in handling the display device. To facilitate handling of larger display size display devices, the ability of the display device to be partially flexible or rollable is often desirable.
Currently, in order to realize the capability of the display device to be bendable or rollable, it is necessary to thin the transparent substrate of the display device by necessity. Before thinning, the non-thinning side of the transparent substrate needs to be protected by an acid-proof film or a glass cover plate, and then the transparent substrate is placed into thinning reaction equipment to be thinned through the reaction between hydrofluoric acid and glass.
However, after the single surface of the transparent substrate is thinned, the thickness of the acid-proof film is greater than that of the glass transparent substrate, when the acid-proof film with high viscosity is separated from the transparent substrate, the edge of the transparent substrate is broken due to the high viscosity and rigidity of the acid-proof film, and the thermal expansion coefficients of the metal foil sealing layers covering the non-thinned sides of the transparent substrate and the transparent substrate are different, so that the whole transparent substrate is deformed, and the thinning precision of the transparent substrate is affected.

Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In a first aspect, referring to fig. 1, a schematic structural diagram of a display module provided in an embodiment of the present application is shown. The display assembly comprises a transparent substrate 11, a metal foil packaging layer 12, a spacer layer 13 and an acid-proof film layer 14; the transparent substrate 11 comprises a thinned area 111 positioned in the middle and non-thinned areas 112 positioned at the periphery of the thinned area 111, and the non-thinned areas 112 are positioned at the edge of the transparent substrate 11; the metal foil packaging layer 12 is attached to the thinned area 111 on the first surface 113 of the transparent substrate 11, and the spacer layer 13 is attached to the metal packaging layer; except for the thinned area 111 of the second surface 114 of the transparent substrate 11, the acid-proof film layer 14 is attached to the transparent substrate 11, the metal foil packaging layer 12, and the spacer layer 13, wherein the first surface 113 and the second surface 114 are two opposite surfaces of the transparent substrate 11, and the second surface 114 is a surface of the transparent substrate 11 emitting light.
The transparent substrate 11 is one of liquid crystal glass substrates, the thickness of the transparent substrate is 0.7 mm, and in order to prevent the acid-proof film layer 14 from being separated from the transparent substrate 11 and generating fragments when the thickness of the transparent substrate 11 is reduced from 0.7 mm to 0.08 mm and is less than 0.08 mm, in the embodiment of the invention, the edge of the transparent substrate 11 is strengthened. Specifically, as shown in fig. 1 and fig. 3, the transparent substrate 11 includes a thinned region 111 located in the middle and non-thinned regions 112 located around the thinned region 111, and the non-thinned regions 112 are located at the edge of the transparent substrate 11. Taking the transparent substrate 11 as a rectangular or square substrate as an example, the frame position which is spaced from four sides of the transparent substrate 11 by a distance greater than or equal to 0.5 cm and less than or equal to 1 cm is the non-thinned area 112, and the non-thinned area 112 surrounds the thinned area 111.
It should be noted that the transparent substrate 11 includes a first surface 113 and a second surface 114 opposite to each other, the second surface 114 is a surface of the transparent substrate 11 for emitting light, and in the process of thinning the transparent substrate 11, the second surface 114 is a hydrofluoric acid surface sprayed during thinning, that is, the second surface 114 is a thinned side of the transparent substrate 11, and the first surface 113 is a non-thinned side of the transparent substrate 11.
The metal foil sealing layer 12 attached on the first surface 113 of the transparent substrate 11 is located in the thinned area 111, that is, the shape and size of the metal foil sealing layer 12 are completely consistent with the shape and size of the thinned area 111, so that the metal foil sealing layer 12 can completely cover the thinned area 111 on the first surface 113, and heat dissipation can be performed by means of the metal foil sealing layer 12 while the transparent substrate 11 is sealed. The metal foil packaging layer 12 may be any metal foil with good ductility, such as an aluminum foil, a copper foil, a tin foil, or a gold foil, which is not limited in this embodiment of the invention.
The spacer layer 13 is attached to the metal foil packaging layer 12, so that the spacer layer 13 is located between the acid-proof film layer 14 and the metal foil packaging layer 12, and the spacer layer 13 may be clean paper or other non-adhesive plastic film, which is not limited in the embodiment of the present invention. In this way, the acid-proof film layer 14 is prevented from being directly attached to the metal foil sealing layer 12, so that the acid-proof film layer 14 is more easily separated from the glass substrate.
In addition, the acid-proof film layer covers the transparent substrate 11, the metal foil sealing layer 12, and the spacer layer 13 until the acid-proof film layer is attached to the non-thinned region 112 of the second surface 114 of the transparent substrate, that is, except for the position of the thinned region 111 of the second surface 114, the other positions of the transparent substrate 11 are covered with the acid-proof film layer to prevent the other positions of the transparent substrate 11 from being subjected to acid corrosion when the thinned region 111 of the second surface 114 is thinned and sprayed. The acid-proof film can be a polytetrafluoroethylene film, a polyethylene film and a polypropylene film, which is not limited in the embodiment of the invention.
As can be seen from the foregoing embodiments, in the embodiments of the present invention, since the transparent substrate 11 includes the thinned region 111 located in the middle and the non-thinned regions 112 located around the thinned region 111, and the non-thinned regions 112 are located at the edge of the transparent substrate 11, the strength of the edge of the transparent substrate 11 is improved, and the problem of debris during the separation process between the acid-proof film layer 14 and the transparent substrate 11 is improved. In addition, the metal foil packaging layer 12 is attached to the thinning area 111 of the first surface 113 of the transparent substrate 11, and the spacer layer 13 is attached to the metal packaging layer, so that the spacer layer 13 is located between the metal foil packaging layer 12 and the acid-proof film layer 14, and thus, the influence of the deformation of the metal foil packaging layer 12 caused by the difference of the thermal expansion coefficients on the separation of the acid-proof film layer 14 can be reduced, the separation of the acid-proof film layer 14 from the transparent substrate 11 is facilitated, and the influence of the metal foil packaging layer 12 on the thinning precision of the transparent substrate 11 is reduced.
In some embodiments, the acid-proof film layer 14 attached to the non-thinned region 112 of the second surface 114 extends a first length toward the thinned region 111, and the first length is greater than or equal to 1 mm. In this way, the thinned region 111 also has the first degree of acid-proof film layer 14, so that corrosion to the non-thinned region 112 can be further avoided, which is beneficial to ensure the strength of the non-thinned region 112. Wherein the first length is the length L shown in fig. 1.
Further, an optical acid-proof glue 15 is applied to the boundary between the acid-proof film layer 14 attached to the second surface 114 and the thinned region 111. It should be noted that the optical acid-proof adhesive 15 may include a monomer, a component, and a prepolymer, and the prepolymer may include epoxy acrylate, urethane acrylate, polyether acrylate, polyester acrylate, and acrylic resin, so that the optical acid-proof adhesive 15 may be quickly attached to a boundary between the acid-proof film layer of the second surface 114 and the thinned region 111, and the sealing property at the boundary between the acid-proof film layer 14 and the thinned region 111 is enhanced, thereby preventing an acidic substance in the thinned region 111 from entering the non-thinned region 112, and further ensuring the strength of the non-thinned region 112. In addition, the straightness of the optical acid-proof glue 15 needs to be greater than 0.5 mm to avoid the influence of the optical acid-proof glue 15 applied at the boundary of the acid-proof film layer 14 of the second surface 114 and the thinning area 111 on the thinning precision of the thinning area 111.
In addition, to further ensure the strength of the non-thinned region 112, the distance between the end of the spacer layer 13 and the transparent substrate 11 is a first value, and the first value is greater than or equal to 0.5 cm and less than or equal to 1 cm. In this way, the spacer layer 13 is also disposed at the boundary between the thinned region 111 and the non-thinned region 112 of the first surface 113, which is further beneficial to reduce the influence of the deformation of the metal foil packaging layer 12 caused by the difference of the thermal expansion coefficients on the separation of the acid-proof film layer 14. Wherein the distance between the end of the spacer layer 13 and the transparent substrate 11 is shown as the distance H in fig. 1.
In one possible implementation, as shown in fig. 1, an acid-proof film layer 14 is attached to the side of the transparent substrate 11. In this way, the acid-proof film layer 14 entirely wraps the transparent substrate 11, and only the thinned area 111 of the second surface 114 is reserved as a thinning processing surface, so that the other parts of the transparent substrate 11 except the thinned area 111 can be prevented from being corroded by the acidic substance. It should be noted that the sidewall of the transparent substrate 11 is an edge of the portion between the first surface 113 and the second surface 114 of the transparent substrate 11.
In another possible implementation, as shown in fig. 2, an optical acid-proof adhesive 15 is attached to the side of the transparent substrate 11. In this way, it is only necessary to attach the acid-proof film layer 14 to the first surface 113 and the second surface 114 of the transparent substrate 11, and attach the optical acid-proof adhesive 15 at the side edge between the first surface 113 and the second surface 114. The optical acid-proof glue 15 not only has a certain sealing effect, but also has a certain elasticity, so that the strength of the transparent substrate 11 at the side edge can be enhanced, and damage to the structure of the transparent substrate 11 caused by scratch at the side edge in the carrying process is avoided.
As can be seen from the foregoing embodiments, in the embodiments of the present invention, since the transparent substrate 11 includes the thinned region 111 located in the middle and the non-thinned regions 112 located around the thinned region 111, and the non-thinned regions 112 are located at the edge of the transparent substrate 11, the strength of the edge of the transparent substrate 11 is improved, and the problem of debris during the separation process between the acid-proof film layer 14 and the transparent substrate 11 is improved. In addition, the metal foil packaging layer 12 is attached to the thinning area 111 of the first surface 113 of the transparent substrate 11, and the spacer layer 13 is attached to the metal packaging layer, so that the spacer layer 13 is located between the metal foil packaging layer 12 and the acid-proof film layer 14, and thus, the influence of the deformation of the metal foil packaging layer 12 caused by the difference of the thermal expansion coefficients on the separation of the acid-proof film layer 14 can be reduced, the separation of the acid-proof film layer 14 from the transparent substrate 11 is facilitated, and the influence of the metal foil packaging layer 12 on the thinning precision of the transparent substrate 11 is reduced.
In addition, since the acid-proof film layer 14 attached to the non-thinned region 112 of the second surface 114 extends to the thinned region 111 by a first length, the first length is greater than or equal to 1 mm, and the optical acid-proof glue 15 is coated at the boundary between the acid-proof film layer 14 attached to the second surface 114 and the thinned region 111, the acidic substance in the thinned region 111 can be further prevented from entering the non-thinned region 112, the strength of the non-thinned region 112 can be further ensured, the acidic substance in the thinned region 111 can be further prevented from entering the non-thinned region 112, and the strength of the non-thinned region 112 can be further ensured.

When the display assembly 1 is installed, the metal foil packaging layer 12 attached to the first surface 113 of the transparent substrate 11, the spacer layer 13 and the acid-proof film layer 14 can be embedded in the bearing groove 21, so that the bearing plate 2 has a certain supporting and limiting effect on the display assembly 1, the influence of deformation of the transparent substrate 11 in the thinning process on thinning precision is further reduced, and fragments generated when the transparent substrate 11 is separated from the bearing plate 2 can be reduced. It should be noted that the carrier plate 2 may be a metal plate or an acrylic plate, or other plate materials with certain strength, which is not limited in the present invention.
