[0044] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting. The display module is an important component of the mobile phone, and when designing, it is required that the thickness of the display layer is thinned, and at the same time, the display module has a longer endurance. Therefore, how to reduce the thickness of the display device and improve the endurance of the display module is a technical problem that needs to be solved at present.

[0045] Figure 1 shows a cross-sectional view of a display module 1 according to an embodiment of the present application, Figure 2 shows a structural schematic view of a flexible circuit board 20 according to an embodiment of the present application, Figure 3 shows a connection relationship schematic view of a flexible circuit board 20 and a first binding part 12 according to an embodiment of the present application, see Figures 1 to 3 The present application provides a display module 1, which comprises a display panel 10 and a flexible circuit board 20.

[0046] In the embodiment of the present application, the display panel 10 comprises a display part 11, a first binding part 12, and a bending part 13, the bending part 13 is connected with the display part 11 and the first binding part 12 respectively, the first binding part 12 is bent to the backlight side of the display part 11 through the bending part 13, and a containing space 14 is defined between the first binding part 12 and the display part 11. In the related art, a support part is generally arranged in the containing space 14, the support part is used for bonding the first binding part 12 and the display part 11, thereby providing support for the first binding part 12 and the display part 11, and further ensuring that the bending part 13 will not be deformed after being bent, so that the bending part 13 always maintains a preset bending angle for fixation, and the damage of electronic components or lines located on the bending part 13 can be effectively avoided. However, the flexible circuit board 20 in the related art is arranged on the backlight side of the display part 11, and components such as a battery and electronic components are also arranged on the backlight side of the display part 11, if the area occupied by the flexible circuit board 20 on the backlight side of the display part 11 is too large, the installation space of the battery and the electronic components will be reduced, which is not conducive to the high endurance and light and thin concept of the display module 1.

[0047] Therefore, the display module 1 in the embodiment of the present application comprises a flexible circuit board 20, the flexible circuit board 20 is bound and connected with the first binding part 12, and at least part of the flexible circuit board 20 extends to the containing space 14.

[0048] According to the embodiment of the present application, the support part in the related art is cancelled, so that the containing space 14 is formed between the first binding part 12 and the display part 11, and then at least part of the flexible circuit board 20 in the present application is inserted into the containing space 14. In this way, the occupied area of the flexible circuit board 20 and the first binding part 12 on the backlight side of the display part 11 can be reduced, more space for installing components such as electronic components and a battery is reserved for the display module 1, and the saved space can be used to set a larger battery capacity, thereby improving the endurance of the battery, so that the display module 1 can provide higher endurance without changing the overall volume.

[0049] For example, the region where the first binding part 12 and the bending part 13 are projected on the display part 11 is a first region, and the region of the display part 11 which does not correspond to the first binding part 12 and the bending part 13 is a second region. In some examples, part of the structure of the flexible circuit board 20 is located in the first region, and another part of the structure of the flexible circuit board 20 is located in the second region. In other examples, all structures of the flexible circuit board 20 are located in the first region, that is, all structures are located in the containing space 14 between the display part 11 and the first binding part 12.

[0050] In some embodiments, the flexible circuit board 20 is provided with a plurality of first binding pins (also referred to as FPC bumps), which are electrically connected to the first binding portion 12 at least partially through the connecting portion.

[0051] In some examples, the connecting portion can be an anisotropic conductive film (ACF), which has the advantages of relatively low process cost and relatively small space occupation, thereby being capable of reducing the area of the flexible circuit board 20 and the first binding portion 12 for mounting the connecting portion. The anisotropic conductive film mainly includes conductive particles, insulating adhesive material, upper protective film and lower protective film. The conductive particles and the insulating adhesive material are located between the upper protective film and the lower protective film. In the process of assembly, the upper protective film and the lower protective film can be torn off, and the anisotropic conductive film is respectively attached to the flexible circuit board 20 and the first binding portion 12, so as to connect the flexible circuit board 20 and the first binding portion 12 through the anisotropic conductive film.

[0052] In the process of signal transmission, the signals of the flexible circuit board 20 are input into the first binding portion 12 through the conductive particles of the anisotropic conductive film, so as to realize the signal transmission between the display portion 11 and the flexible circuit board 20.

[0053] In some embodiments, the flexible circuit board 20 includes a main body portion 21 and an extension portion 22 connected to each other, the main body portion 21 is bound and connected to the first binding portion 12, and part of the structure of the extension portion 22 extends into the accommodating space 14.

[0054] According to the embodiments of the present application, by setting the flexible circuit board 20 as the main body portion 21 and the extension portion 22, and extending part of the structure of the extension portion 22 into the accommodating space 14, the occupied area of the flexible circuit board 20 and the first binding portion 12 on the backlight side of the display portion 11 is reduced, more space for mounting electronic components and battery components is reserved for the display module 1, the saved space can set the battery capacity to be larger, improve the endurance of the battery, so that the display module 1 provides higher endurance without changing the overall volume.

[0055] In the embodiments of the present application, various electronic components are arranged on the main body portion 21 and the extension portion 22, the electronic components include but are not limited to resistors, capacitors, inductors, integrated circuits, conductive tracks, etc., the main body portion 21 and the extension portion 22 jointly constitute the overall structure of the flexible circuit board 20, and the functions respectively responsible for by the main body portion 21 and the extension portion 22 jointly constitute the overall function of the flexible circuit board 20.

[0056] In some examples, referring to Figures 1 to 3In some examples, the body portion 21 and the extension portion 22 can be designed as an integrated structure. In other examples, the body portion 21 and the extension portion 22 can be designed as separate structures and then connected by welding. It should be noted that whether the body portion 21 and the extension portion 22 are designed as separate structures or an integrated structure is not limited herein, and can be determined by a person skilled in the art according to actual needs in specific applications.

[0057] Figure 4 FIG. 2 shows a cross-sectional view of the flexible circuit board 20 and the first binding portion 12 according to an embodiment of the present application. In some embodiments, referring to FIG. 2, Figure 4 The body portion 21 includes a first layer 211 and a second layer 212, and the first layer 211 includes a second binding portion 2111. In the direction of the first binding portion 12 towards the display portion 11, the first layer 211, the second layer 212, and the extension portion 22 are sequentially stacked, the first binding portion 12 is connected to the second binding portion 2111, and the extension portion 22 is arranged on the side of the second layer 212 away from the first layer 211.

[0058] It can be understood that the first layer 211 and the second layer 212 are both circuit layers, and the body portion 21 can be formed by stacking the first layer 211 and the second layer 212.

[0059] In some embodiments, a plurality of first binding pins (also referred to as FPC bumps) are arranged on the second binding portion 2111, and at least part of the plurality of first binding pins are electrically connected to the first binding portion 12 through the connecting portion.

[0060] In some examples, referring to FIG. 2, Figure 4 The thickness of the second layer 212 is greater than the thickness of the first binding portion 12. In this way, the second binding portion 2111 of the first layer 211 can extend to the side of the first binding portion 12 away from the display portion 11 without being bent, and the extension portion 22 can extend to the side of the first binding portion 12 close to the display portion 11 without being bent.

[0061] In some embodiments, the body portion 21 further includes a third layer of circuit board or a fourth layer of circuit layer. It should be noted that the number of layers of circuit layers in the body portion 21 is not limited herein, and can be determined by a person skilled in the art according to actual needs in specific applications. For example, when the flexible circuit board 20 needs to provide sufficient support strength, the body portion 21 can include multiple layers of circuit layers, such as three layers, four layers, five layers, etc.

[0062] In some embodiments, referring to FIG. 2, Figure 1 , Figure 3 and Figure 4, the part structure of the second binding part 2111 is arranged on the side of the first binding part 12 away from the display part 11, and the structure of the second binding part 2111 on the side of the first binding part 12 away from the display part 11 is bound and connected with the first binding part 12. In this way, by overlapping and binding the first binding part 12 and the second binding part 2111 in the direction perpendicular to the display part 11, the area of the flexible circuit board 20 occupying the second area can be further reduced, so that the area occupied by the flexible circuit board 20 and the first binding part 12 on the backlight side of the display part 11 can be reduced, more space for mounting electronic components and battery components and the like is reserved for the display module 1, the saved space can set a larger battery capacity, improve the endurance of the battery, so that the display module 1 can provide higher endurance without changing the overall volume.

[0063] In some embodiments, referring to Figure 1 , the orthographic projection of the second layer 212 on the display part 11 and the orthographic projection of the first binding part 12 on the display part 11 are staggered, and the orthographic projection of the first layer 211 on the display part 11 and the orthographic projection of the first binding part 12 on the display part 11 overlap. In this way, a gap with a certain distance is formed between the second layer 212 and the first binding part 12, and the gap allows a certain error in the process of mounting the flexible circuit board 20 on the first binding part 12, thereby reducing the installation difficulty.

[0064] In some embodiments, referring to Figure 2 and Figure 3 , the second layer 212 is defined with a groove 2121, the groove 2121 is arranged through the second layer 212, and the orthographic projection of the second binding part 2111 on the display part 11 and the orthographic projection of the groove 2121 on the display part 11 at least partially overlap. Since the second binding part 2111 of the first layer 211 and the first binding part 12 are bound and connected, part of the structure of the first binding part 12 will interfere with the second layer 212. Based on this, the groove 2121 is arranged to realize the avoidance of the second layer 212 to the first binding part 12, that is, to allow part of the structure of the first binding part 12 to extend into the groove 2121, so as to avoid the structure interference between the first binding part 12 and the second layer 212, and reduce the possibility of interference in the process of mounting the flexible circuit board 20 on the first binding part 12, which is conducive to reducing the installation difficulty.

[0065] In some examples, when the size of the first binding part 12 and the second binding part 2111 are consistent, the present application can make the orthographic projection of the second binding part 2111 on the display part 11 and the orthographic projection of the groove 2121 on the display part 11 all overlap, so that the first binding part 12 can extend into the groove 2121, thereby avoiding the case that the partial structure of the first binding part 12 interferes with the second layer 212 when the second binding part 2111 of the first layer 211 and the first binding part 12 are bound and connected.

[0066] In other examples, when the size of the first binding part 12 is larger than the size of the second binding part 2111 due to the error of the process, the present application can set the orthographic projection of the groove 2121 on the display part 11 to be larger than the orthographic projection of the second binding part 2111 on the display part 11, so that the first binding part 12 can extend into the groove 2121, thereby avoiding the case that the partial structure of the first binding part 12 interferes with the second layer 212 when the second binding part 2111 of the first layer 211 and the first binding part 12 are bound and connected.

[0067] It should be noted that setting the orthographic projection of the groove 2121 on the display part 11 to be larger than the orthographic projection of the second binding part 2111 on the display part 11 can also allow a certain error in the process of arranging the flexible circuit board 20 on the first binding part 12, that is, the relative position of the flexible circuit board 20 and the first binding part 12 can be offset to complete the binding and connection between the flexible circuit board 20 and the first binding part 12, thereby reducing the installation difficulty of the present application.

[0068] In the embodiment of the present application, the groove 2121 can also function as a crack stopping groove, that is, when the second binding part 2111 is impacted or pressed, if a crack is generated in the second binding part 2111, the crack stopping groove can prevent the crack from further spreading to other positions of the flexible circuit board 20. Secondly, the crack stopping groove can enhance the strength and stability of the flexible circuit board 20, especially when the flexible circuit board 20 is subjected to external force, the crack stopping groove can better disperse the pressure and reduce the impact on other parts of the flexible circuit board 20.

[0069] In some embodiments, referring to Figure 1 The present application also includes a first adhesive layer 30, which connects one side of the extension part 22 facing the display part 11 and one side of the display part 11 facing the extension part 22, respectively. In this way, on the one hand, the connection stability between the extension part 22 and the display part 11 is improved, and on the other hand, the connection between the extension part 22 and the display part 11 can be realized through the first adhesive layer 30, thereby realizing the installation and fixation of the extension part 22 and avoiding the case that the display module 1 is scratched with the extension part 22 and the first binding part 12 when the display module 1 is collided.

[0070] In some embodiments, referring to Figure 1 The display part 11 is defined with a heat dissipation layer 40 on the side facing the first binding part 12, and the extension part 22 is connected with the heat dissipation layer 40 through the first adhesive layer 30 on the side facing the display part 11.

[0071] In some embodiments, referring to Figure 1 The heat dissipation layer 40 and the display part 11 are further defined with a first buffer protection layer 50.

[0072] According to the embodiments of the present application, the heat dissipation layer 40 plays a role in dissipating heat for the display part 11, and the first buffer protection layer 50 plays a role in protecting and supporting the display part 11.

[0073] In some embodiments, referring to Figure 1 The present application further includes a second adhesive layer 60, which is connected with the side of the extension part 22 facing the first binding part 12 and the side of the first binding part 12 facing the extension part 22, respectively.

[0074] According to the embodiments of the present application, the present application cancels the connection part between the display part 11 and the first binding part 12 in the related art, and the extension part 22 of the flexible circuit board 20 extends into the accommodating space 14, and the display part 11 and the first binding part 12 are adhered by the first adhesive layer 30 and the second adhesive layer 60, respectively, so that the flexible circuit board 20 of the present application is fixed between the first binding part 12 and the display part 11. By such arrangement, on the one hand, the occupied area of the flexible circuit board 20 and the first binding part 12 on the backlight side of the display part 11 can be reduced, more space for installing electronic components and battery components and the like can be reserved for the display module 1, the saved space can make the battery capacity larger, and the endurance of the battery can be improved, so that the display module 1 can provide higher endurance without changing the overall volume. On the other hand, the flexible circuit board 20 is adhered to the display part 11 and the first binding part 12 by the first adhesive layer 30 and the second adhesive layer 60, respectively, which can play the role of replacing the connection part in the related art, and play the role of supporting and fixing the display part 11 and the first binding part 12.

[0075] In some embodiments, referring to Figure 1 The first binding part 12 is defined with a second buffer protection layer 70 on the side facing the display part 11, and the extension part 22 is connected with the second buffer protection layer 70 through the second adhesive layer 60 on the side facing the first binding part 12.

[0076] In some examples, the driving chip is arranged on the side of the first binding portion 12 away from the display portion 11, the driving chip is arranged adjacent to the second binding portion 2111, the second binding portion 2111 of the flexible circuit board 20 is arranged on the side of the first binding portion 12 away from the display portion 11, and the extension portion 22 of the flexible circuit board 20 is arranged on the side of the first binding portion 12 close to the display portion 11. In this way, the structural strength of the first binding portion 12 can be improved, and deformation of the first binding portion 12 can be avoided. In addition, the driving chip is arranged on the side of the first binding portion 12 away from the display portion 11, and the structural strength of the first binding portion 12 can be improved by arranging the extension portion 22 and the second binding portion 2111 of the flexible circuit board 20, so that deformation of the first binding portion 12 can be avoided, and the instability of the connection between the driving chip and the first binding portion 12 caused by the deformation of the first binding portion 12 can be avoided, thereby improving the connection stability of the driving chip and the first binding portion 12.
