[0029] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0030] With the advancement of electronic technology, the aesthetic requirements for electronic devices, such as mobile phones, are becoming increasingly demanding. Currently, in the terminal industry, for example, narrow bezels can attract more users, enhance the appeal of electronic products, and accelerate the industry's move towards high-end products. Therefore, narrow bezels have become a common goal in the terminal industry. Terminal designers strive for a perfect overall appearance. However, the limitations of display component design currently make narrow bezel designs impossible. Because perimeter glue filling can reduce the bezel, perimeter glue filling solutions for display components have emerged.

[0031] In the perimeter glue filling scheme of display components, dam glue dispensing is an indispensable key process, which can ensure that the screen perimeter glue does not extend into the interior of the screen and prevent glue overflow.

[0032] In related technologies, such as Figure 1 、 Figure 2 and Figure 3 As shown. During the display assembly manufacturing process, ultraviolet glue 2 (UV) is first applied to the bend of panel 1, and then panel 1 is folded back. To shield the signal interference caused by the integrated circuit 3 (IC), the corresponding position of panel 1 is first covered with an insulating film 4, and then covered with conductive fabric 5. This ensures that the signal emitted by the IC 3 is shielded without affecting the entire device. Finally, dam glue 6 is cured at the height difference.

[0033] However, if Figure 3 As shown, the UV glue 2 and the panel 1 form a step due to the height difference in the thickness direction of the display component. When the conductive cloth 5 and the insulating film 4 are attached to the panel 1, they will be attached to the position of the step between the UV glue 2 and the panel 1. Since there is a step between the end position of the UV glue 2 and the panel 1, and since the conductive cloth 5 and the insulating film 4 cannot be attached according to the contour, there will be a gap at this step. When the dam glue is dispensed, the airflow caused by the space occupied by the filling part of the dam glue 6 cannot be discharged, and hollow bubbles will be formed in the dam glue 6, and then some holes will appear locally, making the dam glue 6 unable to be filled. Due to the presence of bubbles, the dam glue will have bubble problems during the dam glue dispensing process, and the dam glue 6 cannot effectively block the subsequent peripheral glue filling, resulting in the inability to play the role of a dam. Then, when the peripheral glue of the display component is poured, the glue overflows into the inside of the screen, resulting in a defective screen.

[0034] In order to solve the above technical problems, the present disclosure provides a display component and an electronic device.

[0035] The display assembly disclosed herein includes a display panel, a protective layer, a shielding layer, an exhaust portion, and a filler. The display panel includes a first area and a second area, wherein the first area is bent to the backlight side of the display panel through the second area. The protective layer is coated on the second area and extends to the first area, forming a fault between the second area and the first area. The shielding layer is attached to the backlight side of the display panel and partially covers the first area and the protective layer, forming a gap at the fault. The exhaust portion is connected to the gap to discharge the airflow caused by the space occupied by the filler when the gap is filled with the filler.

[0036] In the present disclosure, the display assembly can be applied to various electronic devices.

[0037] The display assembly provided by the embodiments of the present disclosure includes a vent portion communicating with the gap. When the gap is filled with a filler, the airflow generated by the space occupied by the filler can be discharged through the vent portion. By providing the vent portion communicating with the gap, the present disclosure solves the problem of bubbles appearing in the dam glue during the dam glue dispensing process, reduces the proportion of bubbles in the dam glue, and thereby improves the yield rate of the display assembly's perimeter glue dispensing.

[0038] The present disclosure provides a display assembly, referring to Figure 4-7 As shown, the display assembly includes: a display panel 10 , a protective layer 20 , a shielding layer 30 , a vent 50 and a filler 60 .

[0039] The display panel 10 includes a first region A and a second region B, wherein the first region A is bent to the backlight side of the display panel 10 through the second region B. A protective layer 20 is applied to the second region B and extends to the first region A, forming a fault 21 between the second region B and the first region A. A shielding layer 30 is attached to the backlight side of the display panel 10 and partially covers the first region A and the protective layer 20, forming a gap 40 at the fault 21. An exhaust portion 50 is connected to the gap 40 to exhaust the airflow caused by the space occupied by the filler 60 when the gap 40 is filled with the filler 60.

[0040] It should be noted that the backlight side of the display panel 10 refers to the side opposite to the light emitting side of the display panel 10 , and the light emitting side of the display panel 10 refers to the side of the display panel 10 that displays the image.

[0041] Among them, the display panel 10 includes a display area and a non-display area. The display area of ​​the display panel 10 refers to the part of the display panel 10 used to display the picture. The non-display area of ​​the display panel 10 refers to the part of the display panel 10 used to design various external wirings, drive circuits, etc. The non-display area is divided into a bending area and a non-bending area. The bending area is located between the display area and the non-bending area. The first area A refers to the non-bending area of ​​the display panel 10, and the second area B refers to the bending area of ​​the display panel 10. A fan-out line is designed in the bending area of ​​the non-display area, that is, the second area B, for connecting with the signal line in the display area. The non-bending area of ​​the non-display area, that is, the first area A, refers to the part of the display panel 10 used to design a flexible printed circuit board and bind the driver. The first area A is bent to the backlight side of the display panel 10 through the second area B to reduce the border width of the display panel 10 and achieve a narrow border.

[0042] The protective layer 20 covers the second area B of the display panel 10 to protect the fan-out wiring in the second area B and prevent the circuit from breaking when the display panel 10 is bent. The protective layer 20 can be a curing adhesive layer. For example, the protective layer 20 can be an ultraviolet (UV) curing adhesive. After the UV curing adhesive is applied to the second area B at the bending position of the display panel 10, the UV curing adhesive can be quickly cured by ultraviolet radiation, thereby enhancing the structural strength and durability of the display panel 10. After the display panel 10 is bent back, the curing of the UV curing adhesive helps prevent cracks or damage in the bending area of ​​the display panel 10, thereby improving the overall quality and reliability of the display panel 10.

[0043] Compared to heat-curing and visible light-curing adhesives, UV-curing adhesives avoid visible light and exhibit relatively low stress. Furthermore, UV-curing adhesives offer environmental and energy-saving advantages. Compared to traditional heat-curing adhesives, UV-curing adhesives do not require additional heat treatment, thus reducing energy consumption and environmental pollution. Furthermore, the rapid curing properties of UV-curing adhesives shorten production cycles and improve production efficiency.

[0044] A shielding layer 30 is required to be provided on the backlight side of the display panel 10 in the area corresponding to the integrated circuit (IC). The shielding layer 30 is provided to shield the signal interference caused by the IC, ensuring that the signal emitted by the IC is shielded without affecting the normal operation of the entire device.

[0045] The fault 21 is caused by a height difference between the protection layer 20 and the first area A of the display panel 10 . Part of the shielding layer 30 covers the first area A and the protection layer 20 , and a gap 40 is formed at the fault 21 .

[0046] The exhaust portion 50 is connected to the gap 40. As the filler 60 is filled into the gap 40, the air in the gap 40 occupied by the filling portion of the filler 60 will be introduced into the exhaust portion 50, solving the bubble problem of the dam glue in the perimeter glue filling technology of the display component.

[0047] In the present disclosure, the filler 60 may be dam glue or other types of fillers, which is not limited in the present disclosure.

[0048] In the present disclosure, by providing an exhaust portion 50 connected to the gap 40, when the gap 40 is filled with the filler 60, the airflow caused by the space occupied by the filling portion of the filler 60 is discharged, thereby solving the problem of bubbles appearing in the dam glue during the dam dispensing process, reducing the proportion of bubbles in the dam glue, and thereby improving the yield rate of the peripheral glue filling of the display component.

[0049] In some embodiments, reference Figure 4 and Figure 5 As shown, the exhaust portion 50 includes a first exhaust groove 51 provided on the shielding layer 30 , and a notch of the first exhaust groove 51 is communicated with the gap 40 .

[0050] The first exhaust groove 51 may be L-shaped, S-shaped, or other shapes, as long as the notch of the first exhaust groove 51 is connected to the gap 40 . This is not limited in the embodiment of the present disclosure.

[0051] In the embodiment of the present disclosure, by providing a first exhaust groove 51 connected to the gap 40, when the gap 40 is filled with the filler 60, the airflow caused by the space occupied by the filling part of the filler 60 can be discharged through the first exhaust groove 51 in the exhaust part 50, thereby solving the problem of bubbles appearing in the dam glue during the dam dispensing process and reducing the proportion of bubbles in the dam glue.

[0052] In some embodiments, reference Figure 4 and Figure 5 As shown, the shielding layer 30 includes a first shielding layer 31 and a second shielding layer 32 .

[0053] Part of the first shielding layer 31 covers the fault layer 21 to form a gap 40. The second shielding layer 32 is stacked with the first shielding layer 31 on a side of the first shielding layer 31 away from the protective layer 20.

[0054] The first exhaust slot 51 includes a slot 511 penetrating the first shielding layer 31 . The slot 511 is disposed at a portion of the first shielding layer 31 covering the gap 40 .

[0055] The first shielding layer 31 can be an insulating layer. The insulating layer can ensure good electrical insulation, have high resistivity and breakdown field strength, is suitable for high-frequency insulation, and reduces dielectric loss. The insulating layer can play a protective role in electronic devices, preventing current from passing directly, avoiding short circuits and other electrical faults. Of course, the first shielding layer 31 can also be other shielding layers, and the embodiments of the present disclosure are not limited to this. The first shielding layer 31 can be a single layer or a multi-layer, and the embodiments of the present disclosure are not limited to this.

[0056] The second shielding layer 32 can be a conductive fabric, which can shield electromagnetic waves and reduce the harm of electromagnetic radiation to the human body. This is particularly true when used in electronic devices such as mobile phones, where it can effectively reduce the impact of electromagnetic waves on human health. The conductive fabric can also prevent the generation of static electricity, protecting electronic devices from static damage. Of course, the second shielding layer 32 can also be other shielding layers, and this is not limited in the present embodiment. The second shielding layer 32 can be a single layer or multiple layers, and this is not limited in the present embodiment.

[0057] For example, refer to Figure 5As shown, the first venting slot 51 includes a slot 511 extending through the first shielding layer 31. The first shielding layer 31 is designed in a segmented form, separating the first shielding layer 31 at the location where the gap 40 needs to be filled with the filler 60, into a first portion 311, a main body 312, and a second portion 313. The first venting slot 51 is formed between the first portion 311 and the main body 312, and between the main body 312 and the second portion 313. The first portion 311, the main body 312, and the second portion 313 are all adhered to the second shielding layer 32 to form a complete IC-Tape. This is then attached to the corresponding position of the display panel 10. When the gap 40 is filled with the filler 60, the airflow caused by the space occupied by the filler 60 is discharged, solving the problem of bubbles in the dam glue during the dam glue dispensing process, reducing the proportion of bubbles in the dam glue, and thereby improving the yield rate of the perimeter glue of the display assembly, laying a solid foundation for future promotion.

[0058] In some embodiments, reference Figure 4 and Figure 6 As shown, the first exhaust groove 51 further includes a groove bottom (not shown in the figure) provided on the second shielding layer 32 , and the groove bottom does not penetrate the second shielding layer 32 in the thickness direction of the second shielding layer 32 .

[0059] It should be noted that the second shielding layer 32 is disposed on the backlight side of the display panel 10 and is in direct contact with the integrated circuit (IC) for shielding signal interference caused by the integrated circuit (IC).

[0060] The second shielding layer 32 may be a conductive cloth or other shielding layers, which is not limited in the embodiment of the present disclosure.

[0061] In the embodiment of the present disclosure, a portion of the first exhaust groove 51 passes through the first shielding layer 31 in the thickness direction of the second shielding layer 32, while not passing through the second shielding layer 32, so as to shield the signal interference caused by the integrated circuit IC, ensuring that the signal emitted by the IC is shielded without affecting the normal operation of the entire machine.

[0062] In some embodiments, reference Figure 7 As shown, the exhaust portion 50 includes a second exhaust groove 52 provided on the protective layer 20 , and a notch of the second exhaust groove 52 is communicated with the gap 40 .

[0063] The notch of the second exhaust groove 52 may penetrate the protective layer 20 in the thickness direction of the protective layer 20 , or may not penetrate the protective layer 20 , which is not limited in the embodiment of the present disclosure.

[0064] For example, refer to Figure 7As shown, the notch of the second venting groove 52 penetrates the protective layer 20 in the thickness direction of the protective layer 20. The protective layer 20 is designed in a segmented form, and the protective layer 20 is divided into a first protective portion 201, a protective body 202, and a second protective portion 203 at the location where the gap 40 needs to be filled with the filler 60. The second venting groove 52 is formed between the first protective portion 201 and the protective body 202, and between the protective body 202 and the second protective portion 203. The first protective portion 201, the protective body 202, and the second protective portion 203 are attached to the first area A of the display panel 10. When the gap 40 is filled with the filler 60, the airflow caused by the space occupied by the filler 60 is discharged, solving the problem of bubbles in the dam glue during the dam glue dispensing process, reducing the proportion of bubbles in the dam glue, and thus improving the yield rate of the perimeter glue of the display assembly, laying a solid foundation for future promotion.

[0065] In some embodiments, reference Figure 5 and Figure 7 As shown, there are multiple exhaust portions 50, and the multiple exhaust portions 50 are arranged at different end faces of the fault 21, and the end faces are the end faces of the fault 21 at the edge positions of the protective layer 20 and the first area A.

[0066] It should be noted that the number of the exhaust parts 50 can be two, three, or four or more, and the present disclosure does not limit the number of the exhaust parts 50.

[0067] Exemplarily, there are two vents 50, each located on different end faces of the fault 21. Both vents 50 communicate with the gap 40, thereby discharging the airflow caused by the space occupied by the filler 60 when the gap 40 is filled. This solves the problem of bubbles appearing in the dam glue during the dam glue dispensing process, reduces the proportion of bubbles in the dam glue, and thereby improves the yield rate of the display component's perimeter glue potting. This embodiment uses two vents 50 as an example, but the present disclosure is not limited to this.

[0068] It should be noted that there is a step difference between the end surface of the protection layer 20 and the edge of the first area A. In order to ensure the smooth progress of the peripheral glue filling process of the display component, the filler 60 is required to fill the step difference at the edge.

[0069] In some embodiments of the present disclosure, the filler 60 is a dam glue provided on the end surface. The shape of the dam glue is not limited and other types of fillers can also be used, but the present disclosure is not limited thereto. Any component or structure with sealing properties can be used.
