The cover plate 110 covers the display panel 120 and the backlight module 13.
Specifically, the backlight module 13 includes a frame 131 and a backlight element 132, and the backlight element 132 may further include optical devices such as a light guide plate 1321 and a reflective plate 1322. The frame 131 includes a bottom wall 1311 and a sidewall 1312 surrounding the bottom wall 1311, and the bottom wall 1311 and the sidewall 1312 may be integrally formed of the same material, for example, a stainless steel material may be used to integrally form the bottom wall 1311 and the sidewall 1312. Or, different materials may be used to form the bottom wall 1311 and the side wall 1312 according to actual needs, for example, the bottom wall 1311 may be formed by a stainless steel material with a relatively high hardness to improve the carrying capacity of the bottom wall 1311, and the side wall 1312 may be formed by a plastic material to reduce the material cost, where the bottom wall 1311 and the side wall 1312 formed by different materials may be integrally formed by injection molding.
In some embodiments, the backlight assembly 13 may further include a light source (not shown), for example, a side-in light source, where the light source may be located at a side of the light guide plate 1321, so that light enters the light guide plate 1321 from the side of the light guide plate 1321 and is guided to the display panel 120 by the light guide plate 1321. Of course, in other embodiments, the light source may be a backlight type light source, i.e., the light source is disposed below the light guide plate 1321. The reflective plate 1322 is used to reflect the light of the light source back to the light guide plate 1321, so that the light of the light source can be fully utilized.

Specifically, the bottom wall 1311 and the side wall 1312 of the frame 131 cooperate to form a receiving space 1313 for placing optical devices such as the light source, the light guide plate 1321 and the reflection plate 1322, for example, the side wall 1312 may surround the periphery of the bottom wall 1311 to form a groove structure with the bottom wall 1311, and the inside of the groove is the receiving space 1313. The top 1312A of the sidewall 1312 of the frame 131 is connected to the second face 1202 of the display panel 120.

In addition, the first notch 101 and the second notch 102 can be used for placing functional components, so that a non-display area of the display screen reserved for the corresponding functional components can be omitted, and a very narrow frame or a full screen design of the display screen can be realized.
The first glue layer 141 can be a hot melt adhesive, which is a plastic adhesive and has a physical state that changes with temperature within a certain temperature range and a chemical property that does not change. Compared with common glue, the hot melt adhesive has higher adhesive strength and better curing effect. And the thickness of the glue is easier to control, and the design requirement of the narrow frame of the display screen can be met. In addition, the hot melt adhesive belongs to thermoplastic polyurethane, and products bonded by the hot melt adhesive are easier to detach or repair. For example, the hot melt adhesive can be a PUR hot melt adhesive, namely a moisture curing reaction type polyurethane hot melt adhesive, the main component of the hot melt adhesive is an isocyanate-terminated polyurethane prepolymer, the adhesiveness and toughness (elasticity) of the PUR hot melt adhesive can be adjusted, and the PUR hot melt adhesive has excellent adhesive strength, temperature resistance, chemical corrosion resistance and aging resistance.
For example, UV (Ultraviolet) glue, also called photosensitive glue or UV-curable glue, can be used as the first glue layer 141, and UV glue is a kind of adhesive that can be cured only by irradiation of Ultraviolet (UV) light, and can be used as an adhesive, and can also be used as a glue for paint, ink, etc. The UV glue curing principle is that a photoinitiator (or photosensitizer) in a UV curing material generates active free radicals or cations after absorbing ultraviolet light under the irradiation of ultraviolet light, and initiates monomer polymerization and crosslinking chemical reaction, so that the adhesive is converted from a liquid state to a solid state within several seconds. For example, the first glue layer 141 may be black uv glue, which can block light and shield light, and has the characteristics of strong adhesion, fast curing, thin glue dispensing, and the like, and for example, the first glue layer 141 may be formed between the outer surface 1314 of the sidewall 1312 opposite to the accommodating space 1313 and the side of the display panel 120 by using a glue dispensing process or a glue coating process. The first glue layer 141 formed by black uv glue can play a role in shading light and prevent light leakage.
For example, OCA (optical Clear Adhesive) glue or the like can be used as the first glue layer 141. The OCA optical adhesive has the characteristics of no color, transparency, high light transmittance (total light transmittance is more than 99%), high adhesive force, high weather resistance, water resistance, high temperature resistance, ultraviolet resistance and the like, has controlled thickness, can provide uniform spacing, and does not generate the problems of yellowing, peeling and deterioration after long-term use.

By providing the second glue layer 143, the waterproof performance of the waterproof glue 14 can be further reinforced.
The adhesion occurs between the interfaces in contact with each other, and the formation of the adhesion is required to have both wettability and adhesion.

Wetting is a prerequisite for bonding. The surface energy and wettability relation, the solid surface energy size determines the wettability, the basic condition of the liquid on the solid surface can spread spontaneously is that the surface energy of the liquid is less than the surface energy of the solid, the lower the surface energy of the liquid, the higher the surface energy of the solid is, the more favorable the spreading is, otherwise, the spreading is not favorable. The same liquid has good wettability on a solid surface with large surface energy, so that the surface energy is an important factor influencing the bonding strength, and the wettability of the adhesive on an adherend can be enhanced by reducing the surface energy of the adhesive or increasing the surface energy of the adherend, thereby improving the bonding strength.
