For example, the display screen may also be a full screen, with only display areas and no non-display areas. Wherein, functional components such as fingerprint module, touch-control circuit set up the below at the full screen. For example, the display screen may also be a shaped screen.

Wherein the housing 40 may form an outer contour of the electronic device 100. The cover plate 10 may be fixed to the case 40, and the cover plate 10 and the case 40 form a closed space to accommodate the display module 20, the battery 30, and the like.

In some embodiments, the housing 40 may be made of a metal material such as magnesium alloy, stainless steel, etc. It should be noted that the material of the housing 40 according to the embodiment of the present application is not limited to this, and other manners may also be adopted, for example, the housing 40 may include a non-metal portion and a metal portion. For example, the housing 40 may be a plastic housing. For example, the housing 40 may be a ceramic housing. For example, the housing 40 may be a metal and plastic mating housing structure. The shell 40 may be formed by cold working, hot working, injection molding, extrusion molding, compression molding, blow molding, cast molding, and gas assist molding. For example, the shell 40 is made of aluminum or an aluminum alloy, and can be formed by cold working methods such as lathing, milling, planing, drilling, and drawing. For example, the housing 40 may be made of a non-metal material by a non-metal material molding method such as injection molding.

The display module 20 is installed in a closed space formed by the cover plate 10 and the housing 40, and the display module 20 includes a buffer 201, a back plate glass 202 and an integrated protection glass 203.

The battery 30 is installed in the sealed space formed by the cover plate 10 and the housing 40, and the battery 50 is electrically connected to the display module 20 to provide power to the electronic device 100.

The embodiment of the present application provides a display module 20, and referring to fig. 2 to 4, the display module 20 includes a back plate glass 202, an integrated cover glass 203, and a buffer 201.

The cushion material 201, the back plate glass 202, and the integrated cover glass 203 are provided in this order from the inside to the outside (as shown in fig. 2).

For example, when the display module 20 is disposed on the electronic device 100, the buffer 201 is closest to the back surface of the electronic device 100, followed by the backplane glass 202, and the integrated cover glass 203 is farthest from the back surface of the electronic device.

The buffer 201 is attached to the back plate glass 202 for protecting the back plate glass 202.

Among them, the buffer 201 is used to protect the back plate glass 202 because the back plate glass 202 is fragile. The buffer 201 provides protection under any conditions, such as during installation, during display screen transportation, during reliability testing, and during user use.

The integrated cover glass 203 is used to protect the back plate glass 202 and to seal the back plate glass 202.

On one hand, the integrated protection glass 203 has a protection effect, namely, the back plate glass 202 is prevented from being broken due to external force impact; on the other hand, the organic luminescent material has a sealing function, namely, the organic luminescent material encapsulated between the integrated protective glass 203 and the back plate glass 202 can be prevented from being corroded by water and oxygen. Have had the effect of the cover plate of protection glass and encapsulation among the prior art display module promptly concurrently. Through adopting the integrated protection glass 203 that has protect function and sealing function simultaneously, come to constitute display module assembly 20 with backplate glass 202 and buffer 201, saved OCA layer and encapsulation apron among the prior art display module assembly, realized the frivolous design of display module assembly, both saved the material, promoted the luminousness again.

In some embodiments, the integrated cover glass further comprises a color film layer attached to the back glass 202.

Due to the progress of the current depolarizer (POL-LESS) technology, the polarizer technology is to be replaced by coe (Color Filter On encapsulation), so that when an upper polarizer is not used in the display module, a Color Filter layer can be deposited On the lower surface of the integrated protective glass 21. The new structure makes the display module 20 very thin and light, and significantly improves the transmittance.

In some embodiments, the display module 20 further includes a first polarizer 204;

the buffer 201, the backplane glass 202, the integrated protective glass 203 and the first polarizer 204 are sequentially arranged from inside to outside (as shown in fig. 3);

In which the first polarizer 204 is disposed on the outer layer, the back plate glass 202 and the integrated cover glass 203 may be manufactured as a whole. The first polarizer 204 is used to absorb the reflected light of the electrode, thereby improving the contrast of the display panel.

In some embodiments, the display module 20 further includes a second polarizer 205;

the buffer 201, the backplane glass 202, the second polarizer 205 and the integrated protective glass 203 are sequentially arranged from inside to outside (as shown in fig. 4);

the second polarizer 205 is attached to the integrated cover glass 203 and the back plate glass 202 respectively.

Wherein, when the second polarizer 205 is placed between the integrated cover glass 203 and the back plate glass 202, the back plate glass 202 and the integrated cover glass 203 are separately manufactured. The second polarizer 205 is used to absorb the reflected light of the electrode, thereby improving the contrast of the display panel.

In some embodiments, the display module 20 further includes a protective film;

the protective film is disposed on a first surface of the integrated protective glass 203, the first surface being a surface away from the backplane glass 202.

The protective film can protect the integrated protective glass 203, and the protective effect of the integrated protective glass 203 on the backplane glass 202 is optimized.

In some embodiments, the protective film is a flexible protective film.

Among them, in order to further optimize the protective effect of the integrated cover glass 203 on the back plate glass 202, the protective film is preferably a flexible protective film.

It should be noted that when an external object contacts the protective film, the flexible protective film can reduce the hard contact strength between the integrated protective glass 203 and the object, and reduce the possibility of breakage of the integrated protective glass 203, thereby prolonging the service life of the integrated protective glass 203.

In some embodiments, the thickness of the integrated cover glass 203 ranges from 0.5mm to 1.0 mm.

It should be noted that, a person skilled in the art may specifically set the thickness of the integrated cover glass 203 according to actual situations, and is not limited specifically herein.

In some embodiments, the integrated cover glass 203 is made of an aluminum-silicon material or a sodium-calcium material.
