Description

Technical Field

[0001] This invention relates to the field of terminal equipment technology, and more specifically to a display screen assembly and a terminal device. Background Technology

[0002] Mobile phone displays require flexible printed circuit boards (FPCs) to connect to the motherboard. FPCs are large and often thick. Since the display's FPC is typically positioned directly beneath the battery, the thickness of the FPC limits the battery's thickness, thus affecting battery capacity, given the limited internal space. Alternatively, the display's FPC might be positioned above the speaker, also limiting speaker thickness and resulting in reduced audio performance. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] To this end, embodiments of the present invention provide a display assembly whose FPC can avoid the installation space of a mobile phone battery or speaker, thereby enabling the use of a larger capacity battery or a speaker with higher audio performance.

[0005] An embodiment of the present invention also proposes a terminal device.

The flexible board includes a first bent portion and a first main body portion extending from the screen body toward the back of the screen body. The first main body portion is located on the back of the screen body, and the first bent portion and the first main body portion are on different planes. The integrated circuit is mounted on the first main body portion. The FPC is connected to the first main body portion, wherein the FPC, the first main body portion, and the screen body are arranged in the thickness direction of the screen body.

[0007] According to the display assembly of the present invention, the FPC overlaps with the first main body in the thickness direction, thereby avoiding the FPC from occupying the space in the terminal device used for installing batteries or speakers in the thickness direction. As a result, batteries or speakers with a greater thickness can be installed in the corresponding space, and the terminal device can install batteries with a larger capacity or speakers with higher audio performance.

[0008] In some embodiments, the display assembly further includes a first pad sandwiched between the screen body and the first main body portion.

[0012] In some embodiments, the display assembly further includes a second pad sandwiched between the first body portion and the second body portion, the connecting portion and the second pad being located on both sides of the integrated circuit, wherein the second pad is located on the side of the first body portion near the first bend portion.

[0013] In some embodiments, the flexible board further includes a second bent portion and a third main portion extending from the first main portion toward the side away from the screen body. The second bent portion and the first bent portion are respectively located at both ends of the first main portion.

The FPC and the third main portion are arranged and bound together in the thickness direction of the screen body.

[0014] In some embodiments, the display assembly further includes a third pad sandwiched between the first body portion and the third body portion.

[0015] In some embodiments, the display assembly further includes a fourth pad sandwiched between the first body portion and the FPC, the thickness of the fourth pad being equal to the sum of the thicknesses of the third pad and the third body portion.

[0016] In some embodiments, a receiving cavity is formed between the third pad and the fourth pad, and the integrated circuit is disposed on the side of the first main body away from the screen body and located in the receiving cavity.

[0017] In some embodiments, the projections of the third main body, the integrated circuit, and the fourth pad on the FPC do not overlap.

[0018] In some embodiments, the first bent portion, the first main body portion, the second bent portion, and the third main body portion are integrated.

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] In related technologies, such as Figure 7 As shown, taking a mobile phone as an example, the flexible board 2 can be encapsulated on the left or right side of the phone. The portion encapsulated by the flexible board 2 (especially FPC4) corresponds to the battery area or the upper / lower motherboard area. Alternatively, the flexible board 2 can also be encapsulated at the bottom of the phone. However, regardless of where the flexible board 2 is encapsulated on the phone, the thickness of the encapsulated area will limit the dimensions of the corresponding battery area or upper / lower motherboard area in the thickness direction. This will limit the thickness of the speaker on the battery 10 or motherboard area, affecting battery capacity or audio performance.

[0034] To solve the above problems, the following will combine... Figures 1-6 A display assembly 100 according to an embodiment of the present invention is described.

[0035] The display assembly 100 according to an embodiment of the present invention includes a screen body 1, a flexible board 2, an integrated circuit 3, and an FPC 4. The flexible board 2 includes a first bent portion 22 and a first main body portion 21 extending from the screen body 1 toward the back surface of the screen body 1. The first main body portion 21 is located on the back surface of the screen body 1, and the first bent portion 22 and the first main body portion 21 are on different planes. The first bent portion 22 is a double bend, so that the first main body portion 21 is parallel to the screen body 1.

[0036] Integrated circuit 3 is mounted on the first main body 21. FPC4 is connected to the first main body 21, wherein FPC4, the first main body 21, and the screen 1 are arranged in the thickness direction of the screen 1. That is, FPC4 is located on the lower or upper side of the first main body 21, and on the projection plane perpendicular to the thickness direction of the screen 1, the projection of FPC4 largely coincides with the projection of the first main body 21.

[0037] According to the embodiment of the present invention, the display assembly 100, the FPC4 and the first body 21 overlap in the thickness direction, thereby avoiding the FPC4 from occupying the space in the terminal device used for installing the battery or speaker in the thickness direction. As a result, a battery 10 with a larger thickness or a speaker can be installed in the corresponding space, and the terminal device can install a battery 10 with a larger capacity or a speaker with higher audio performance.

[0038] like Figure 1 and Figure 2As shown, the display assembly 100 according to a first embodiment of the present invention includes a screen body 1, a flexible board 2, an integrated circuit 3, an FPC 4, and a first pad 5. The FPC 4 is located on the side of the first main body 21 facing away from the screen body 1 and is bound to the first main body 21. The first pad 5 is sandwiched between the screen body 1 and the first main body 21, and the side of the first pad 5 near the first main body 21 has a receiving cavity. The integrated circuit 3 is disposed on the side of the first main body 21 facing the screen body 1 and is located in the receiving cavity.

[0039] By setting the first pad 5, the first main body 21 is ensured to be parallel to the screen 1, while the bending angle of the first bending portion 22 is not too large and could cause damage, thus ensuring the performance of the flexible board 2. Furthermore, the integrated circuit 3 is located on the side of the first main body 21 facing the screen 1, allowing the FPC 4 to fit snugly against the first main body 21, thereby reducing the maximum thickness dimension of the display assembly 100 and resulting in a compact structure. Figure 1 For example, if the diagram shows the packaging of the display assembly corresponding to the battery area, then the portion above the screen 1, the left side of the stacked structure of FPC 4, the first main body 41, and the integrated circuit 3 is the portion that can accommodate the battery. Figure 7 In contrast, the FPC in the encapsulation structure does not occupy thickness space in the thickness direction, so the thickness of the battery can be significantly improved.

[0040] Specifically, the first bending portion 22 undergoes two bends in opposite directions to form a U-shape, with the opening of the first bend facing the same horizontal direction as the screen body 1, thereby ensuring that the first main body portion 21 is parallel to the screen body 1. The first pad 5 is made of foam, and the first pad 5 is bonded to the back side of the screen body 1 and the first main body portion 21 by adhesive, thereby achieving the positioning of the first main body portion 21. Figure 2 As shown, on the projection surface perpendicular to the thickness direction of the screen 1, the projection of FPC4 is hidden on the projection of the flexible plate 2.

[0041] In addition, the dimension of the first pad 5 in the thickness direction of the screen body 1 is larger than the maximum dimension of the integrated circuit 3 in the thickness of the screen body 1. With the support of the first pad 5, the integrated circuit 3 is separated from the screen body 1, thereby effectively preventing the integrated circuit 3 from contacting the screen body 1 and being damaged.

[0042] like Figure 3As shown, the display assembly 100 according to a second embodiment of the present invention includes a screen body 1, a flexible board 2, an integrated circuit 3, an FPC 4, a first pad 5, and a second pad 6. The FPC 4 includes a connecting portion 41 and a second main body portion 42 arranged at an angle. The connecting portion 41 is bound to the first main body portion 21, and a receiving cavity is formed between the second main body portion 42 and the first main body portion 21. The integrated circuit 3 is formed on the side of the first main body portion 21 away from the screen body 1, and the integrated circuit 3 is located in the receiving cavity. The second pad 6 is sandwiched between the first main body portion 21 and the second main body portion 42. The connecting portion 41 and the second pad 6 are located on both sides of the integrated circuit 3, wherein the second pad 6 is located on the side of the first main body portion 21 near the first bending portion 22.

[0043] According to the embodiments of the present invention, the display assembly 100 can mount the second main body 42 of the FPC4 on the side of the first main body 21 away from the screen body 1, even when the integrated circuit 3 is mounted on the side of the first main body 21 away from the screen body 1. This ensures that the terminal device can accommodate a battery 10 with a larger capacity or a speaker with higher audio performance. Furthermore, the connecting portion 41 and the second pad 6 together support the second main body 42, ensuring that the gap between the second main body 42 and the first main body 21 is maintained at a set distance. This effectively prevents the angle between the connecting portion 41 and the second main body 42 from being too small, which could affect the performance of the FPC4. Moreover, the integrated circuit 3 is hidden in the receiving cavity and located between the connecting portion 41 and the second pad 6, providing high protection for the integrated circuit 3.

[0044] Specifically, such as Figure 3 As shown, the connecting portion 41 and the second main body portion 42 are perpendicular to each other, and the connecting portion 41 and the second pad 6 are respectively disposed at opposite ends of the second main body portion 42. The receiving cavity is formed both between the first main body portion 21 and the second main body portion 42, and also between the connecting portion 41 and the second pad 6. The depth of the receiving cavity is greater than the maximum dimension of the integrated circuit 3 in the thickness direction of the screen body 1, thereby effectively preventing the second main body portion 42 from accidentally moving and damaging the integrated circuit 3, and ensuring the performance of the integrated circuit 3.

[0045] like Figure 4 As shown, the display assembly 100 according to a third embodiment of the present invention includes a screen body 1, a flexible board 2, an integrated circuit 3, an FPC 4, a first pad 5, a third pad 7, and a fourth pad 8. The flexible board 2 further includes a second bent portion 23 and a third main body portion 24 extending from the first main body portion 21 away from the screen body 1, with the second bent portion 23 and the first bent portion 22 located at opposite ends of the first main body portion 21. The FPC 4 and the third main body portion 24 are located on the side of the first main body portion 21 away from the screen body 1, and the FPC 4 and the third main body portion 24 are arranged and bonded in the thickness direction of the screen body 1.

[0046] The third pad 7 is sandwiched between the first main body portion 21 and the third main body portion 24. The fourth pad 8 is sandwiched between the first main body portion 21 and the FPC4, and the thickness of the fourth pad 8 is equal to the sum of the thicknesses of the third pad 7 and the third main body portion 24. The third pad 7 and the fourth pad 8 form a receiving cavity, and the integrated circuit 3 is disposed on the side of the first main body portion 21 opposite to the screen body 1 and located in the receiving cavity.

[0047] According to the display assembly 100 of the present invention, even when the integrated circuit 3 is required to be installed on the side of the first main body 21 away from the screen body 1, the second main body 42 of the FPC4 can be installed on the side of the first main body 21 away from the screen body 1, thereby ensuring that the terminal device can install a battery 10 with a larger capacity or a speaker with higher audio performance. Furthermore, the second bent portion 23 and the third main body 24, together with the fourth pad 8, jointly support the FPC4, thereby ensuring that the FPC4 is spaced above the first main body 21. The fourth pad 8 also ensures the fixation of the FPC4, effectively preventing the FPC4 from accidentally moving into the space where the battery 10 and speaker are to be installed. Moreover, the third pad 7 provides stable support for the second bent portion 23, thereby effectively preventing damage to the flexible board 2 caused by excessive bending angles of the second bent portion 23.

[0048] Specifically, the third pad 7 is bonded to the two opposite sides of the first main body 21 and the third main body 24. The third pad 7 provides stable support for the third main body 24 and the second bending part 23, thereby effectively preventing the flexible plate 2 from being damaged due to excessive bending angles of the second bending part 23.

[0049] In some embodiments, the projections of the third main body 24, the integrated circuit 3, and the fourth pad 8 on the FPC4 do not overlap. That is, the integrated circuit 3 can be mounted between the third main body 24 and the fourth pad 8, and the integrated circuit 3 has high protection.

[0050] It should be noted that the first bending portion 22, the first main body portion 21, the second bending portion 23, and the third main body portion 24 are integrated. The first bending portion 22 is maintained at a set angle by a first pad 5 bonded between the screen body 1 and the first main body portion 21, and the second bending portion 23 is maintained at a set bending angle by a third pad 7 bonded between the first main body portion 21 and the third main body portion 24. The first bending portion 22, the first main body portion 21, the second bending portion 23, and the third main body portion 24 all extend from the screen body 1.

[0051] like Figure 5 and Figure 6As shown, the display assembly 100 according to the fourth embodiment of the present invention includes a screen body 1, a flexible board 2, an integrated circuit 3, and an FPC 4. The FPC 4 is sandwiched between the screen body 1 and the first main body portion 21, and the FPC 4 is bonded to the first main body portion 21. The integrated circuit 3 is disposed on the side of the first main body portion 21 away from the screen body 1. The area on the FPC 4 other than the bonding area also includes a device area 9 for connecting devices to the FPC 4 circuitry.

[0052] According to the display assembly 100 of the present invention, the FPC4 maintains a set distance between the screen body 1 and the first main body 21, effectively preventing damage to the first bending portion 22 due to excessive bending angle. Furthermore, the bonding area of ​​the FPC4 overlaps with the first main body 21 in the thickness direction of the screen body 1, effectively preventing the FPC4 from occupying space used for installing the battery 10 or speaker, and ensuring that the display assembly 100 can be assembled with the thicker battery 10 or speaker.

[0053] Furthermore, by setting up a device area 9 parallel to the first main body 21 in the horizontal direction of the screen 1, the electronic components on the FPC4 can be installed in the device area 9, effectively preventing the electronic components from contacting and being damaged by the first main body 21, thus ensuring the performance of the FPC4. Moreover, since the FPC4 is in close contact with the side of the screen 1, the thickness of the area on the FPC4 where the electronic components are located will not be too large, thus ensuring that the display assembly 100 can still be assembled with the thicker battery 10 or speaker.

[0054] It should be noted that, regardless of whether the flexible board 1 is encapsulated on the left, bottom, or bottom of the mobile phone, the electronic components on the device area 9 can be any one or more of resistors, capacitors, and touch screen ICs, depending on the design requirements of the terminal device.

[0055] The terminal device according to the present invention includes a display screen assembly 100 as described in any of the above embodiments. The terminal device also includes a structural support plate, a battery 10 and a speaker. The structural support plate is attached to the back side of the screen body 1 and is arranged side by side with the FPC4 in the horizontal direction of the screen body 1. The battery 10 and the speaker are installed on the side of the structural support plate away from the screen body 1.
