In the present embodiment, the screen assembly refers to a display assembly, which at least includes a display body, a transparent cover plate 31 located above the display, and a substrate 33 located below the display. The display screen body is a screen module 32, which at least includes a light source module and a touch module of the screen. The transparent cover plate 31 is positioned above the screen assembly, when a user uses the terminal, the actual touch part of the user is the transparent cover plate 31, the screen module 32 is protected, and the transparent cover plate has certain toughness, so that cracks can not be generated due to pressing in the operation of the user; the transparent cover plate 31 has a high hardness, and it is determined that it has sufficient surface strength so as to be wear-resistant and not easily scratched. In this embodiment, the transparent cover plate 31 may be made of glass, or may be made of acrylic, wherein the glass cover plate may have higher hardness than the acrylic cover plate, and the acrylic cover plate has better toughness. The substrate 33 is used for supporting the transparent cover 31 and the screen module 32, and facilitating assembly and installation of the transparent cover 31 and the screen module 32.

The transparent cover plate 31 and the screen module 32 are directly bonded; the transparent cover plate 31 and the screen module 32 can be specifically bonded by OCA optical cement 35.

The light transmission rate is more than 90%, the cementing strength is good, the curing can be carried out at room temperature or middle temperature, and the curing shrinkage is small. The OCA optical cement is one of the raw materials of the important touch screen. The optical acrylic adhesive is made into a double-sided adhesive tape without a base material, and then a layer of release film is respectively adhered to an upper bottom layer and a lower bottom layer. That is, the OCA optical adhesive is a double-sided adhesive without a substrate having an optical transparency characteristic. Its advantages are high clarity, high light transmission (99% of total light transmittance), high adhesion, high weatherability, water resistance, high resistance to high temp and ultraviolet, controlled thickness, uniform spacing, and no yellowing, peeling and deterioration.

The transparent cover 31 and the substrate 33 are adhered by a sealant 34 surrounding the screen module 32. The sealant 34 is a frame-shaped sealant, and the sealant 34 in this embodiment is disposed around the screen module 32, that is, the screen module 32 is disposed in the frame of the sealant 34. The main purpose of the sealant 34 is to bond the transparent cover plate 31 on the screen module 32 and the substrate 33 under the screen module 32; after the frame glue 34 is bonded, the sealing from the transparent cover plate 31 to the screen module 32 and then to the substrate 33 is realized, wherein the screen module 32 is completely contained in the containing cavity formed by the transparent cover plate 31, the frame glue 34 and the substrate 33, so that the waterproofness of the screen module 32 is improved. In the embodiment, the size of the inner frame of the sealant 34 is matched with the screen module 32, which means that the size of the inner frame of the sealant 34 is exactly matched with the screen module 32, but the size of the inner frame of the sealant 34 is slightly different from that of the screen module 32 based on the different materials of the sealant 34, and if the sealant 34 has certain elasticity, the size of the inner frame of the sealant 34 is preferably slightly smaller than that of the screen module 32; if the frame glue 34 has a weak elasticity, the inner frame size of the frame glue 34 is consistent with the screen module 32. The size of the outer frame of the sealant 34 can be set to be less than or equal to the size of the transparent cover plate 31, that is, the sealant 34 does not extend out of the transparent cover plate 31, so that a larger space can be reserved for mounting the screen assembly.

Optionally, the frame glue 34 and the screen module 32 are provided with a flange and a groove which are matched with each other, and the frame glue 34 and the screen module 32 are installed in a limiting manner through the flange and the groove. The flange and the groove are respectively disposed on the sealant 34 and the screen module 32 in a matching manner, wherein the flange and the groove can be disposed on the sealant 34 and the screen module 32 at will, for example, the groove is disposed on the sealant 34, and then the screen module 32 at the corresponding position is disposed with the flange, and vice versa. In order to improve the stability of the position limiting installation, a plurality of sets of flanges and grooves may be provided, and the flanges and the grooves may be alternately provided on the frame adhesive 34 and the screen module 32.

Specifically, in the present embodiment, the sealant 34 may be foam. The foam adhesive is prepared by coating one or two surfaces of EVA or P E foam as a base material with solvent-type or hot-melt pressure-sensitive adhesive and then compounding with release paper. The foam rubber has good elasticity and viscosity, so that the foam rubber has sealing and damping effects, and has excellent sealing performance, compression deformation resistance, flame retardance, wettability and the like.

In the embodiment, the transparent cover 31 is used to protect other components of the screen assembly, such as the screen module 32, the substrate 33, and the like, the transparent cover 31 has a higher hardness, such as glass, and the transparent cover 31 needs a certain flexibility, so that the transparent cover 31 can ensure that the screen assembly can be bent within a certain range, and thus, the transparent cover 31 can be made of multiple layers of thin glass, the structure of the multiple layers of glass can ensure the strength of the multiple layers of glass, and the thin glass provides the flexible characteristic for the multiple layers of glass.

In the embodiment, the transparent cover 31 and the substrate 33 are bonded by the sealant 34 surrounding the screen module 32, and the size of the sealant 34 is equivalent to that of the screen module 32, wherein the sealant 34 surrounds the screen module 32 and is disposed at the outer edge of the screen module 32 after the screen assembly is manufactured, but in order to further ensure the sealing property, the sealant 34 is usually disposed with a certain elasticity, such as foam, silica gel, etc., so that the actual size of the sealant 34 can be slightly smaller than the size of the screen module 32. At least the upper surface and the lower surface of the sealant 34 have viscosity for bonding the top transparent cover plate 31 and the substrate 33, and the inner side surface of the sealant 34 also has viscosity for bonding the screen module 32.
