Referring to fig. 1 and fig. 2, an embodiment of the present application provides an electronic device 100, which may be a smart phone or a tablet computer.

The electronic device 100 includes a housing 10, a display 20, and a camera module 30. An accommodating space is formed between the casing 10 and the display 20, and the accommodating space is used for accommodating components such as a main board (not shown), a battery, the camera module 30, and the like of the electronic device 100, and the casing 10 can protect internal components of the electronic device 100.

The display screen 20 includes a cover 21 and a display component. The cover plate 21 may be made of transparent plastic or glass, and the cover plate 21 is used to protect the display module, thereby preventing the display module from being scratched and affecting the display function.

Referring to fig. 3, the display module includes a backlight module 26, a display module and a sealant G.

The backlight module 26 has a first through hole 261, and the first through hole 261 penetrates through the backlight module 26 along the thickness direction of the backlight module 26. The display module includes a liquid crystal panel 23, a first polarizer 22, and a second polarizer 24. The liquid crystal panel 23 is stacked on the light-emitting side of the backlight module 26 and covers the first through hole 261, the first polarizer 22 is disposed on a side of the liquid crystal panel 23 facing away from the backlight module 26, the second polarizer 24 is disposed on a side of the liquid crystal panel 23 facing the backlight module 26, the second polarizer 24 is provided with a second through hole 241, the radius of the second through hole 241 is smaller than that of the second through hole 241, and the edge of the first through hole 261 is covered by a portion of the second polarizer 24 corresponding to the edge of the second through hole 241.

The sealant G is adhered to the wall surface of the first through hole 261 and covers at least the edge of the second through hole 241 of the second polarizer 24.

In the above embodiment, because the radius of the first through hole 261 is smaller than the radius of the second through hole 241, the portion of the second polarizer 24 corresponding to the edge of the second through hole 241 is set to cover the edge of the first through hole 261, so that the second polarizer 24 can shield the light leakage of the backlight module 26 from the first through hole 261 to some extent, and only the sealant G adhered to the wall surface of the first through hole 261 needs to cover at least the edge of the second through hole 241, so as to better prevent the backlight module 26 from light leakage, as shown in fig. 2, when the camera module 30 is disposed at the corresponding position of the first through hole 261, the shooting effect of the camera module 30 is not affected by the light leakage of the backlight module 26, so as to ensure the shooting effect of the camera module 30.

The cover plate 21 covers a side of the first polarizer 22 opposite to the liquid crystal panel 23, so that the arrangement of the cover plate 21 can prevent the first polarizer 22 and the liquid crystal panel 23 located inside the first polarizer 22 from being scratched. The outer surface 21a of the cover 21 is used as a light exit surface of the display 20 for the display light to pass through to display a display image. In the structure that the display screen 20 is a touch screen, the outer surface of the cover plate 21 is also the surface of the touch operation, so that under the protection of the cover plate 21, the touch operation is not easy to damage the structure inside the display screen 20, and a good touch feeling can be achieved.

In some embodiments, the cover plate 21 is adhered to the first polarizer 22 by an optical adhesive layer. The optical adhesive has the characteristics of no color, transparency, high light transmittance, high adhesion, high weather resistance, water resistance, high temperature resistance, ultraviolet resistance and the like, has controlled thickness, can provide uniform spacing, and does not cause the problems of yellowing, peeling and deterioration after long-term use.

In some embodiments, as shown in fig. 3, the sealant G may just cover the edge of the second through hole 241, so that the sealant G can prevent light leakage caused by a gap between the backlight module 26 and the second polarizer 24, thereby reducing interference in shooting of the camera module 30.

In other embodiments, as shown in fig. 4, the adhesive sealing member G covers the edge of the second through hole 241 and is adhered to the liquid crystal panel 23, so that the adhesive sealing member G can prevent light leakage between the backlight module 26 and the second polarizer 24, and also prevent light leakage at the joint of the second polarizer 24 and the liquid crystal panel 23, and thus the adhesive sealing member G has a good light shielding effect, and prevents light of the backlight module 26 from interfering with the imaging quality of the camera module 30.

It should be noted that the first through hole 261 may have a slight offset with respect to the second through hole 241, as long as the adhesive sealing member G can block the bonding gap between the backlight module 26 and the second polarizer 24, or the bonding gap between the second polarizer 24 and the liquid crystal panel 23 at the edge of the second through hole 241 after adhering to the sidewall of the first through hole 261.

In some embodiments, the projection patterns of the wall surface of the first through hole 261 and the wall surface of the second through hole 241 on the liquid crystal panel 23 are concentric circles, specifically, the size of the portion of the second polarizer 24 exposed from the edge of the first through hole 261 relative to the backlight module 26 is consistent, so that when the sealant G is formed by using a dispensing method, the uniformity of the sealant output amount is conveniently controlled, and the finally formed sealant G is uniformly attached between the inner wall of the first through hole 261 and the second polarizer 24.

In some embodiments, the difference between the radius of the first through hole 261 and the radius of the second through hole 241, i.e., the distance d between the edge of the first through hole 261 and the edge of the second through hole 241, ranges from 0.08mm to 0.22 mm. In this range, when the sealant G is formed, the portion of the second polarizer 24 covering the second through hole 241 may provide a sufficient dispensing surface, so as to improve the adhesion stability of the sealant G, and the dispensing surface is not too large to easily form a large white edge on the light emitting display side of the display module, which affects the overall appearance of the display screen 20.

For example, in some embodiments, the radius of the first through-hole 261 is 0.08mm, 1mm, 2mm, or 0.22mm smaller than the radius of the second through-hole 241.

In some embodiments, as shown in fig. 4, the backlight module 26 includes a backlight plate 26a and a frame 26 b. The backlight plate 26a is provided with a clearance groove 26c, and the frame 26b covers the inner wall of the clearance groove 26c to form a first through hole 261. In this embodiment, the frame 26b can improve the installation stability of the backlight plate 26 a.

It should be noted that the frame 26b of the backlight module 26 may be omitted. For example, as shown in fig. 5, the backlight module 26 includes a backlight plate 26a, and the first through hole 261 is opened in the backlight plate 26 a. Thus, the sealant G is adhered to the sidewall of the first through hole 261, that is, the sealant G is adhered to the backlight plate 26a, so that when the sealant G is connected to the second polarizer 24 or the edge of the liquid crystal panel 23 corresponding to the second through hole 241, the sealant G can have a good light shielding effect to maintain the shooting effect of the camera module 30.

As shown in fig. 4 and fig. 5, in the embodiment that the backlight module 26 includes the backlight plate 26a, the light shielding layer 25 is sandwiched between the backlight plate 26a and the second polarizer 24, the light shielding layer 25 at least covers the edge of the backlight plate 26a corresponding to the first through hole 261, so that a certain light shielding is formed between the backlight plate 26a and the second polarizer 24 by the light shielding layer 25, and the light of the backlight plate 26a at the edge of the first through hole 261 is prevented from being emitted from the edge close to the second through hole 241, so that the light shielding layer 25 is better in light shielding effect by combining the sealing member G, so as to maintain the good shooting effect of the camera module 30.

It should be noted that the light shielding layer 25 is not necessary, and as shown in fig. 6, after the backlight plate 26a and the second polarizer 24 are stacked together, a good light shielding effect can still be achieved between the backlight plate 26a and the second polarizer 24 by using the sealant G.

Referring again to fig. 2, the camera module 30 includes a lens 31, a lens holder 32 and an image sensor 33. The lens 31 is mounted on the lens holder 32 so that light entering the image sensor 33 can meet imaging requirements. In this embodiment, when the camera module 30 is installed in the electronic device 100, part of the structure of the lens 31 is accommodated in the first through hole 261, and the emitted light of the backlight module 26 is shielded by the sealing member G and does not enter the first through hole 261, so that the light leakage phenomenon is effectively avoided, and abnormal shooting of the camera module 30 is prevented.

In some embodiments, the camera module 30 is electrically connected to the main board of the electronic device 100 through the flexible circuit board 30a, wherein the connector of the flexible circuit board 30a may be a board-to-board connector 30b, so that the camera module 30 can be easily assembled and disassembled when the electronic device 100 is assembled.
