[0042] The screen assembly is the display device of an electronic device. As users' requirements for electronic devices gradually increase, the screen ratio of electronic devices gradually increases. In order to make electronic devices visually borderless, the screen assembly uses a flexible screen and adopts COP (Chip On Plastic) packaging.

[0043] In the related art, the chip is located on the panel 2 of the screen assembly. Figure 1 As shown, the panel 2 includes a first plate 21, a second plate 22 and a third plate 23 connected in sequence, the second plate 22 is semicircular, the chip 7 and the cable 8 are located on the third plate 23, and the third plate 23 is located on the back side of the first plate 21. Figure 2 and Figure 3 As shown, the BP film 3 in the screen assembly includes a first straight portion 31 and a second straight portion 33, wherein the first straight portion 31 is opposite to the first plate 21 of the panel 2, and the second straight portion 33 is opposite to the third plate 23 of the panel 2. However, since the edge of the second plate 22 is not supported, when the screen assembly is impacted by external force, the edge of the second plate 22 is prone to cracking.

[0044] In view of the above technical problems, the present disclosure provides a screen assembly, such as Figure 4-Figure 6As shown, the screen assembly includes a support member 1, a panel 2 and a BP film 3. The panel 2 includes a first plate 21, a second plate 22 and a third plate 23 connected in sequence, the second plate 22 is in a semicircular arc shape, and the first plate 21 and the third plate 23 are located on both sides of the support member 1. The BP film 3 includes a first straight portion 31, a bent portion 32 and a second straight portion 33, the first straight portion 31 is fitted with the inner side of the first plate 21, the bent portion 32 is fitted with the inner side of the second plate 22, the bent portion 32 includes a groove 321 and a first support structure 322 and a second support structure 323 located on both sides of the groove 321, and the first support structure 322 and the second support structure 323 are used to support both sides of the second plate 22.

[0045] The first supporting structure 322 and the second supporting structure 323 of the bending portion 32 are used to support the edge of the second plate body 22 .

[0046] The screen assembly further includes a polarizer 4, which covers the outer sides of the first plate 21, the second plate 22 and the third plate 23. The polarizer 4 is used to convert the natural light passing through the polarizer 4 into polarized light, so that the panel 2 can display color images.

[0047] The panel 2 is U-shaped as a whole, and a chip 7 and a cable 8 are provided on the third board 23 of the panel 2, and the chip 7 and the cable 8 are located on the side of the third board 23 away from the first board 21, so that the panel 2 can achieve COP packaging, visually increasing the screen ratio of the screen component in the electronic device.

[0048] The BP film 3 and the support member 1 are used to support the panel 2. The support member 1 may include embo, foam, and the like.

[0049] The screen assembly further includes a cover plate 5, which covers the polarizer 4. The cover plate 5 may be a glass cover plate, and there is an OCA (Optically Clear Adhesive) glue 9 between the cover plate 5 and the polarizer 4. The OCA glue 9 has a high light transmittance and good bonding strength, and can achieve a stable connection between the cover plate 5 and the polarizer 4.

[0050] In the technical solution provided by the embodiment of the present disclosure, since the bending portion 32 of the BP film 3 has the first supporting structure 322 and the second supporting structure 323, the BP film 3 can provide good support for the edge of the bending area of ​​the screen assembly. In this way, when the screen assembly is hit by an external force, the screen assembly is not prone to breakage.

[0051] In some examples, such as Figure 5As shown, the width D1 of the first straight portion 31 is greater than the width D2 of the second straight portion 33. The first straight portion 31 is used to support the first plate 21 of the panel 2, so the width D1 of the first straight portion 31 is equal to the width of the first plate 21, so as to better support the first plate 21.

[0052] Since the third plate 23 of the panel 2 is used to carry the chip 7 and the cable 8, the width of the third plate 23 can be set to be smaller than the width of the first plate 21. The second straight portion 33 of the BP film 3 is used to support the third plate 23, so the width D2 of the second straight portion 33 can be the same as the width of the third plate 23, so that the width D2 of the second straight portion 33 is smaller than the width D1 of the first straight portion 31.

[0053] Of course, in other examples, such as Figure 6 As shown, the width D1 of the first straight portion 31 may also be equal to the width D2 of the second straight portion 33 .

[0054] In some examples, such as Figure 5 As shown, the width D2 of the groove 321 is greater than the width D4 of the third plate body 23 .

[0055] In some examples, such as Figure 5 As shown, the width D2 of the second straight portion 33 is less than or equal to the width D3 of the groove 321. Setting the width of the second straight portion 33 to be smaller can reduce the material used for the second straight portion 33, thereby reducing the manufacturing cost of the screen assembly. In addition, setting the width D2 of the second straight portion 33 to be narrower will not affect the effect of the second straight portion 33 supporting the third plate 23.

[0056] Of course, in some other examples, the width D2 of the second straight portion 33 may also be greater than the width D3 of the groove 321 .

[0057] In some examples, such as Figure 5 As shown, the shape of the groove 321 is rectangular. In this way, the bending portion 32 is easy to process.

[0058] The embodiment of the present disclosure does not specifically limit the shape of the groove 321 , and the shape of the side of the groove 321 may also be an arc shape or the like.

[0059] In some examples, such as Figure 5 As shown, the bottom of the groove 321 is the end of the first straight portion 31. That is, the depth of the groove 321 is the length of the bent portion 32. In this way, the bent portion 32 can be prevented from affecting the bending of the second plate body 22 of the panel 2.

[0060] In some examples, such as Figure 1 As shown, both sides of the end of the second plate body 22 have first rounded corners 221. Figure 5As shown, the outer sides of the first support structure 322 and the second support structure 323 have a second fillet 324, and the radius of the second fillet 324 is the same as that of the first fillet 221. In this way, the bent portion 32 can be more consistent with the edge of the second plate body 22, so that the bent portion 32 can provide better support for the second plate body 22, so that the first fillet 321 is not easy to break under external impact.

[0061] In some examples, such as Figure 5 As shown, the screen assembly further includes adhesive 6 , the first straight portion 31 and the second straight portion 33 are connected by the adhesive 6 , and a portion of the adhesive 6 is opposite to the groove 321 .

[0062] In some examples, such as Figure 5 As shown, the distance D5 between the first straight portion 31 and the second straight portion 33 is greater than the thickness of the support member 1 .

[0063] An embodiment of the present disclosure also provides an electronic device, which includes the above-mentioned screen assembly.

[0064] The electronic device may be a mobile phone or a tablet computer.

[0065] The technical solution provided by the embodiment of the present disclosure is that the BP film 3 in the screen assembly can provide good support for the panel 2. Therefore, when the electronic device is impacted by external force, the panel 2 in the screen assembly is not easily broken, thereby making the electronic device less likely to be damaged when impacted by external force.

[0066] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
