However, after the single side of the transparent substrate is thinned, the thickness of the acid-proof film is larger than that of the transparent substrate of glass, when the acid-proof film with high viscosity is separated from the transparent substrate, the edge of the transparent substrate is broken due to high viscosity and rigidity of the acid-proof film, and the thermal expansion coefficients of the metal foil packaging layers covered on the non-thinned side of the transparent substrate and the non-thinned side of the transparent substrate are different, so that the whole of the transparent substrate is deformed, and the thinning precision of the transparent substrate is affected.

Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
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 utility model. 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 assembly according to an embodiment of the present utility model is shown. The display component 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 includes a thinned region 111 at the middle and a non-thinned region 112 around the thinned region 111, and the non-thinned region 112 is located at the edge of the transparent substrate 11; the metal foil packaging layer 12 is attached to the thinned region 111 of the first surface 113 of the transparent substrate 11, and the spacer layer 13 is attached to the metal foil packaging layer; except for the thinned region 111 of the second surface 114 of the transparent substrate 11, the metal foil packaging layer 12 and the spacer layer 13 are all attached with an anti-acid film layer 14, 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 from which light is emitted.
The transparent substrate 11 is a liquid crystal glass substrate, and has a thickness of 0.7 mm, and in order to prevent the problem of separation of the acid-proof film 14 from the transparent substrate 11, which occurs when the thickness of the transparent substrate 11 is reduced from 0.7 mm to 0.08 mm or less, in the embodiment of the present utility model, the edge of the transparent substrate 11 is reinforced. Specifically, as shown in fig. 1 and 3, the transparent substrate 11 includes a thinned region 111 at the middle and a non-thinned region 112 at the periphery of the thinned region 111, and the non-thinned region 112 is located at the edge position of the transparent substrate 11. Taking the transparent substrate 11 as a rectangular or square substrate as an example, the frame position with the distance between the four sides of the transparent substrate 11 being greater than or equal to 0.5 cm and less than or equal to 1 cm is a non-thinned region 112, and the non-thinned region 112 surrounds the periphery of the thinned region 111.
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 on which light is emitted from the transparent substrate 11, and the second surface 114 is a hydrofluoric acid surface sprayed during thinning of the transparent substrate 11, that is, the second surface 114 is a thinning side of the transparent substrate 11, and the first surface 113 is a non-thinning processing side of the transparent substrate 11.
The metal foil packaging layer 12 attached to 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 packaging layer 12 and the shape and size of the thinned area 111 are completely consistent, so that the metal foil packaging 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 packaging layer 12 while packaging of the transparent substrate 11 is achieved. The metal foil packaging layer 12 may be any metal foil with good ductility, such as aluminum foil, copper foil, tin foil or gold foil, which is not limited in the embodiment of the present utility model.
A 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 a clean paper or other non-adhesive plastic film, which is not limited in the embodiment of the present utility model. In this way, the acid-proof film layer 14 can be prevented from being directly attached to the metal foil packaging 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 packaging 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, the position except the thinned region 111 of the second surface 114, other positions of the transparent substrate 11 are covered with the acid-proof film layer, so that other positions of the transparent substrate 11 are prevented from being corroded by acid during thinning spraying in the thinned region 111 of the second surface 114. The acid-proof film may be a polytetrafluoroethylene film, a polyethylene film, or a polypropylene film, which is not limited in the embodiment of the present utility model.
As can be seen from the above embodiments, in the embodiment of the present utility model, since the transparent substrate 11 includes the thinned region 111 at the middle and the non-thinned region 112 around the thinned region 111, and the non-thinned region 112 is located at the edge position of the transparent substrate 11, the strength of the edge position of the transparent substrate 11 is improved, and thus the problem of chipping of the acid preventing film layer 14 and the transparent substrate 11 during the separation process is improved. The metal foil packaging layer 12 is adhered to the thinned region 111 of the first surface 113 of the transparent substrate 11, and the spacer layer 13 is adhered to the metal foil 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 change of the metal foil packaging layer 12 caused by the difference of 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 and 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 resistant film layer 14 attached to the non-thinned region 112 of the second surface 114 extends a first length to the thinned region 111, the first length being greater than or equal to 1 millimeter. In this way, the thinned region 111 also has the acid-proof film layer 14 of the first degree, so that corrosion to the non-thinned region 112 can be further avoided, which is beneficial to ensuring the strength of the non-thinned region 112. Wherein the first length is the length shown as L in fig. 1.
Further, an optical acid-proof adhesive 15 is applied at 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 composition and a prepolymer, and the prepolymer may include epoxy acrylate, polyurethane acrylate, polyether acrylate, polyester acrylate and acrylic resin, so that the optical acid-proof adhesive 15 may be attached to the boundary between the acid-proof film layer of the second surface 114 and the thinned region 111 relatively quickly, so as to enhance the tightness of the boundary between the acid-proof film layer 14 and the thinned region 111, further avoid the acidic substances in the thinned region 111 from entering the non-thinned region 112, and further ensure the strength of the non-thinned region 112. In addition, the straightness of the optical acid-proof adhesive 15 needs to be greater than 0.5 mm to avoid the influence of the optical acid-proof adhesive 15 on the thinning accuracy of the thinning region 111 when the interface between the acid-proof film layer 14 of the second surface 114 and the thinning region 111 is smeared.
In addition, to further secure 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, which 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 arranged at the junction of the thinned region 111 and the non-thinned region 112 of the first surface 113, so that the influence of the variation 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 is reduced. 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 region 111 of the second surface 114 is reserved as a thinned surface, so that other parts of the transparent substrate 11 except the thinned region 111 can be prevented from being corroded by acidic substances. The sidewall of the transparent substrate 11 is an edge where a portion between the first surface 113 and the second surface 114 of the transparent substrate 11 is located.
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, only the acid-proof film layer 14 needs to be attached to the first surface 113 and the second surface 114 of the transparent substrate 11, and the optical acid-proof adhesive 15 needs to be attached to the side between the first surface 113 and the second surface 114. The optical acid-proof adhesive 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 the 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 above embodiments, in the embodiment of the present utility model, since the transparent substrate 11 includes the thinned region 111 at the middle and the non-thinned region 112 around the thinned region 111, and the non-thinned region 112 is located at the edge position of the transparent substrate 11, the strength of the edge position of the transparent substrate 11 is improved, and thus the problem of chipping of the acid preventing film layer 14 and the transparent substrate 11 during the separation process is improved. The metal foil packaging layer 12 is adhered to the thinned region 111 of the first surface 113 of the transparent substrate 11, and the spacer layer 13 is adhered to the metal foil 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 change of the metal foil packaging layer 12 caused by the difference of 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 and 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 for a first length, the first length is greater than or equal to 1 mm, and the optical acid-proof adhesive 15 is smeared at the boundary between the acid-proof film layer 14 attached to the second surface 114 and the thinned region 111, the acidic material of 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 material of 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.
In a second aspect, as shown in fig. 4, 5 and 6, an embodiment of the present utility model further provides a carrying device, which is used for carrying the display assembly 1 according to any embodiment of the first aspect, where the carrying device includes a carrying board 2; the carrier plate 2 includes a carrier groove 21, and the metal foil packaging layer 12, the spacer layer 13 and the acid-proof film layer 14 attached to the first surface 113 of the transparent substrate 11 are embedded in the carrier groove 21.
The carrier plate 2 has a bar-shaped plate structure with a certain thickness, and a carrier groove 21 facing upward is formed in the middle of the carrier plate 2, and the notch of the carrier groove 21 and the surface of the carrier plate 2 are in the same horizontal line. When the display assembly 1 is installed, the metal foil packaging layer 12, the spacer layer 13 and the acid-proof film layer 14 attached to the first surface 113 of the transparent substrate 11 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, further, the influence of deformation on the thinning precision in the thinning process of the transparent substrate 11 is 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 acryl plate, or other plates with a certain strength, which is not limited in this utility model.
In some embodiments, as shown in fig. 5, two opposite surfaces of the carrying board 2 are provided with a carrying groove 21, and a display assembly 1 is fixed at each carrying groove 21. Thus, one carrier plate 2 can fix two display components 1, thereby improving the acid etching efficiency of the transparent substrate 11 of the display component 1.
The display module 1 to be thinned can be fixed in the carrying groove 21 of the carrying plate 2 by vacuum, thermal release glue, common double sided glue or other physical adsorption means.

In this way, when fixing the display module 1 to be thinned, vacuum can be injected from the mouth of the vacuum guide groove, and then the vacuum is made to reach the vacuum accommodating groove 23 via the vacuum guide groove 22, so that the display module 1 to be thinned can be adsorbed in the carrying groove 21 under the action of the vacuum.
As shown in fig. 7, in the case that the display module 1 to be thinned is fixed in the carrying groove 21 of the carrying plate 2 by the adsorption manner of the thermal separation glue, at least two glue carrying grooves 24 are opened at the bottom of the carrying groove 21, and the glue carrying grooves 24 are used for accommodating the thermal separation glue. In this way, the thermal separation glue can be distributed at the bottom of the carrying groove 21 through at least two glue carrying grooves 24, so that the display assembly 1 can be fixed in the carrying groove 21 of the carrying plate 2 through the thermal separation glue.
Furthermore, as shown in fig. 4, in some embodiments the carrier device further comprises a clip 3; the clip 3 has a receiving cavity in which the display module 1 fitted on the carrier plate 2 is received. In this way, a plurality of display components 1 embedded on the bearing plate 2 can be fixed in the accommodating cavity of the clamp 3, so that the transparent substrates 11 of the display components 1 can be subjected to acid etching operation at the same time, and the transparent substrates 11 of the display components 1 can be protected to a certain extent while the acid etching efficiency of the transparent substrates 11 of the display components 1 is improved.

As can be seen from the foregoing embodiments, in the embodiment of the present utility model, since the carrying device includes the carrying board 2, the carrying board 2 includes the carrying groove 21, and the metal foil packaging layer 12, the spacer layer 13 and the acid-proof film layer 14 attached to the first surface 113 of the transparent substrate 11 are embedded in the carrying groove 21, when the display assembly 1 is installed, the metal foil packaging layer 12, the spacer layer 13 and the acid-proof film layer 14 attached to the first surface 113 of the transparent substrate 11 can be embedded in the carrying groove 21, so that the carrying board 2 has a certain supporting and limiting effect on the display assembly 1, further reducing the influence of the deformation of the transparent substrate 11 on the thinning precision, and reducing the fragments generated when the transparent substrate 11 is separated from the carrying board 2.
