Referring to fig. 1, fig. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal 100 includes a display assembly, which mainly includes a window 10, a display module 20, a middle frame 40, a Printed Circuit Board (PCB) 50, a function module 60, and a housing 70. The mobile terminal 100 may further include a battery 90. The display module 20 is electrically connected to the printed circuit board 50.

The function module 60 includes a first function portion 61, a connecting segment 63, and a second function portion 62. The connecting end is connected between the first functional portion 61 and the second functional portion 62. Specifically, the connection segment 62 may be a Flexible Printed Circuit (FPC). In other words, the connection section 63 is formed on the flexible printed circuit board. The two functional portions of the functional module 60 are connected by a flexible printed circuit board. It is understood that the flexible printed circuit board may be bent. Therefore, the function module 60 can be made to be substantially S-shaped, thereby forming a clearance position and providing a space for installing other components.

In one possible implementation manner of the present invention, the first functional part 61 may be a camera assembly, and the second functional part 62 may be a connector, such as a BTB connector. It is understood that, in other embodiments of the present invention, the first functional portion 61 may also be a flashlight, and the second functional portion 62 may be a connector. Alternatively, the second functional portion 62 may be other functional components, such as a gravity sensor and the like. This is not exhaustive.

The display module 20 includes a first embedding portion 201, and the first functional portion 61 of the functional module 60 can be embedded in the first embedding portion 201. The first insertion part 201 may be formed in the shape of a hole, but the embodiment is not limited thereto. The first insertion part 201 may be formed in a groove shape.

Further, the planar shape of the first insertion portion 201 may be a polygon, for example, a quadrangle. Here, the planar shape means a shape in a vertical direction of the front face.

The planar shape of the first embedding portion 201 may vary depending on the shape of the function module 60 embedded in the first embedding portion 201, the ratio of embedding of the function module 60 in the first embedding portion 201, and the like.

The printed circuit board 50 includes a second embedded portion 501, and the second functional portion 62 of the functional module 60 is embedded in the second embedded portion 501. The second insertion portion 501 may be formed in the shape of a hole, but is not limited thereto. The second insertion portion 501 may also be formed in a groove shape. As an example of the second insertion part 501 having a groove shape, the second insertion part 501 may be formed in a socket type. It will be appreciated that the two functional portions 62 of the functional module 60 are typically thicker than the thickness of the printed circuit board 50. Therefore, it can also be said that some parts of the second functional part 62 are embedded in the second embedding part 501.

More specifically, please refer to FIG. 2. The projection of the first insertion portion 201 on the printed circuit board 50 is arranged side by side with the second insertion portion 501. In other words, the projection of the first embedding portion 201 on the printed circuit board 50 and the second embedding portion 501 do not have an overlapping portion. Therefore, a better space avoidance effect can be formed, and the space below the first functional part 61 can be used for installing other components.

In the embodiment of the present invention, the first functional part 61 of the functional module 60 is embedded in the first embedding part 201 and the second functional part 62 is embedded in the second embedding part 501 in the whole thickness of the functional module 60, so that the whole thickness of the mobile terminal 100 can be reduced.

In a possible implementation manner of the present invention, the middle frame 40 is provided with a third embedded portion 401, and the connecting section 63 of the function module 60 passes through the third embedded portion 401. The third insertion portion 401 may be formed in the shape of a hole, but is not limited thereto. The third insertion portion 401 may also be formed in a groove shape.

More specifically, please refer to fig. 2. In a possible implementation manner of the present invention, the projection of the third embedding portion 401 on the display module 20 is connected between the projections of the first embedding portion 201 and the second embedding portion 501 on the display module 20. Here, after the connecting section 63 of the functional module 60 passes through the third insertion portion 401, the first functional portion 61 is inserted into the first insertion portion 201, and the second functional portion is inserted into the second insertion portion 501. Since the thickness of the connection section 63 itself is small, the connection section 63 passing through the third embedding portion 401 has a negligible influence on the overall thickness of the mobile terminal.

Please refer to fig. 3. In a possible implementation manner of the present invention, the projection of the third embedding portion 401 on the display module 20 may further include the projection of the first embedding portion 201 and the second embedding portion 501 on the display module 20. In other words, the projection of the second embedded portion 501 on the display module 20 and the projection of the first embedded portion 201 included in the third embedded portion 401 on the display module 20.

In one possible implementation of the present invention, the middle frame 40 may be fixed to the outer shell 70. Some portions of the function module 60 are connected to the middle frame 40 so that the function module 60 can be fixed to the inside of the housing 70 via the middle frame 40.

The window 10 and the display module 20 are stacked. In particular, the window 10 may be disposed in front of the display module 20. The window 10 may protect the front surface of the display module 20 and expose the image or video displayed in the display module 20 to the outside.

The window 10 may have an exposed area EA exposing an image or video of the display module 20 and a non-exposed area NEA blocking external visibility. The non-exposed area NEA may include a light shielding layer, for example, a black pad layer, so that the inside of the mobile terminal 100 may not be visible.

The non-exposed area NEA may include a receiving area RA1 for transmitting signals from the outside to the function module 60. Visible light or infrared light can be externally moved to the function module 60 through the receiving area RA 1. In particular, the receiving area RA1 at least partially overlaps the first inlay 201. Preferably, the projection of the receiving area RA1 on the display module 20 is included in the first embedded part 201. In addition, the signal generated in the function module 60 can be transmitted to the outside via the reception area RA 1. However, the signal transmitted through the reception area RA1 is not limited thereto, but may vary according to the function module 60 (e.g., the type of the sensor module).

The display module 20 may include a display area DA for displaying an image and a non-display area NDA for not displaying an image. The non-display area NDA may be disposed outside the display area DA.

The non-display area NDA may include a sealing area SA and a gasket area PA. The sealing area SA may seal the inside of the display module 20, and the gasket area PA may transmit and/or receive signals to/from the outside. The non-exposed area NEA of the window 10 may be disposed in front of the non-display area NDA of the display module 20 and prevent the non-display area NDA of the display module 20 from being seen from the outside. Preferably, the first embedding portion 201 may be formed in the non-display area NDA of the display module 20. For example, the first embedding portion 201 may be formed in the pad area PA of the non-display area NDA.

The position of the first insertion portion 201 may be changed according to the position of the function module 60. For example, when the functional module 60 is located in the middle of the pad area PA, the first embedding portion 201 may be formed in the middle of the pad area PA. Although not shown, in some embodiments, when the function module 60 may not be located in the middle of the pad area PA, for example, the function module 60 may be located on the right or left side of the pad area PA, and the first embedding portion 201 may be formed on the right or left side of the pad area PA.

Please refer to fig. 4. The display module 20 may include a plurality of layers, for example, an upper plate 210 and a lower plate 220. The upper plate 210 may include a color filter, and the lower plate 220 may include a thin film transistor and a circuit wire connected to the thin film transistor. A layer of liquid crystal material may be disposed between the upper plate 210 and the lower plate 220. However, the composition of the layers of the display module 20 is not limited thereto, and may vary according to the type of the display module 20. For example, when the display module 20 is an organic light emitting display device, a liquid crystal material layer disposed between the upper plate 210 and the lower plate 220 may be omitted, or an organic/inorganic material layer may be formed therebetween.

The lower plate 220 may include an overlapping region 221 overlapping the upper plate 210, and a non-overlapping region 222 not overlapping the upper plate 210. The upper plate 210 and the lower plate 220 may be bonded and sealed by a sealing member 230. The first embedding portion 201 may be formed in the non-overlapping region 222 of the lower plate 220 of the display module 20. The first embedding portion 201 may be separated from the overlapping region 221 to form a predetermined gap.

It is understood that the gap between the first embedding portion 201 and the overlapping region 221 may vary according to the resolution of the display module 20. For example, when the resolution is high, the gap may be formed larger, and when the resolution is low, the gap may be formed smaller.

It is understood that the printed circuit board 50 may include at least one of a microprocessor, a microcontroller, an Application Specific Integrated Circuit (ASIC), and a general purpose peripheral interface. The printed circuit board 50 may be disposed at the rear side of the display module 20.

It is understood that, in the embodiments described herein, the number of the function modules 60 is described as singular, and the first embedding portion 201, the second embedding portion 501, and the third embedding portion 401 corresponding to the function modules 60 may also be described as singular. However, the number of the functional modules 60 and the first, second, and

third insertion portions

201, 501, 401 is not limited to this, and may be a plurality. In some embodiments, the first functional parts of the two functional modules may be respectively disposed in first embedding parts spaced apart from each other. For example, the two functional modules may be camera modules for three-dimensional images.
