Generally, the middle area of the touch panel 10 is used as the display area 15 , and the non-display area 16 is arranged around the display area 15 . For example, the non-display area 16 is provided on the top side or the bottom side of the display area 15 .

Since the touch panel 10 is made of light-transmitting material, the user can check the content displayed on the screen of the terminal 1000 through the display area 15 .

In order to make the terminal 1000 more beautiful, ink can be sprayed on the lower surface 14 of the non-display area 16. The color of the ink is, for example, white, black or blue, which can be set according to actual needs. The ink can not only meet the user's requirements for different colors of the terminal 1000, but also can cover the internal structure of the terminal 1000 to achieve the effect of beautifying the terminal 1000.

It can be understood that the shape of the touch panel 10 may be specifically designed according to the shape of the terminal 1000, for example, a rectangle with rounded corners.

Further, the touch panel 10 defines an installation hole 17 . In this embodiment, the mounting hole 17 is a through hole penetrating the upper surface 12 and the lower surface 14 . In other embodiments, the mounting hole 17 may be a blind hole formed in the lower surface 14 .

In this embodiment, the mounting hole 17 is in the shape of an oblong body. Of course, in other embodiments, the mounting hole 17 can be designed in different shapes according to specific requirements, such as a circular or oval shape. Therefore, the example of the shape of the mounting hole 17 in this embodiment cannot be understood as a limitation of the present invention.

In some embodiments, the decorative ring 20 is sleeved in the installation hole 17 and fixedly connected with the touch panel 10 . The fingerprint chip packaging structure 30 is accommodated in the decoration ring 20 and fixedly connected with the decoration ring 20 .

Generally, the receiver of the terminal 1000 is disposed on the top area of the terminal 1000 . Therefore, in order to prevent the installation hole 17 from interfering with the receiver, preferably, the installation hole 17 is opened at the bottom area of the touch panel 10 , thereby providing a larger design space for the installation hole 17 . Further, the installation hole 17 is opened in the non-display area 16 of the touch panel 10 .

Preferably, the installation hole 17 is opened in the middle of the bottom area of the touch panel 10, so that the touch panel 10 has a substantially symmetrical structure. In this way, the terminal 1000 is more beautiful, and secondly, it is convenient for users to operate.

When the mounting hole 17 is a through hole, when manufacturing the input assembly 100, the decorative ring 20 can be installed into the mounting hole 17 from the bottom of the touch panel 10 first, and then at the gap point between the inner wall of the mounting hole 17 and the decorative ring 20 Put glue, so that the decorative ring 20 is fixedly connected with the touch panel 10.

Then put the fingerprint chip packaging structure 30 into the decorative ring 20 from above the touch panel 10, and use glue to fix the fingerprint chip packaging structure 30 and the decorative ring 20.

When the mounting hole 17 is a blind hole, the fingerprint chip packaging structure 30 can be loaded into the decorative ring 20 first, and then the decorative ring 20 with the fingerprint chip packaging structure 30 can be loaded into the mounting hole 17, and the decoration can be fixed with glue. Circle 20 and touch panel 10.

Referring to FIGS. 3-5 , in some embodiments, the decorative ring 20 includes a decorative ring 21 and a supporting edge 22 . The supporting edge 22 extends inwardly from the inner wall 211 of the decoration ring 21 .

The supporting edge 22 of the decorative ring 20 in the embodiment of the utility model can support and position the fingerprint chip packaging structure 30 , thereby improving the assembly efficiency of the fingerprint chip packaging structure 30 and the decorative ring 20 .

That is to say, the fingerprint chip packaging structure 30 is supported on the supporting edge 22 . When putting the fingerprint chip packaging structure 30 into the decoration ring 21, you can press the fingerprint chip packaging structure 30 from top to bottom. If the position of the fingerprint chip packaging structure 30 can no longer be moved, it means that the fingerprint chip packaging structure 30 has been against the support. On the side 22, and installed to predetermined position.

It can be understood that the decoration ring 21 is formed with a receiving hole 212 , and the supporting edge 22 is located in the receiving hole 212 . The accommodating hole 212 can be in the shape of a straight column, or in other words, the inner wall 211 is in the shape of a straight line, so that the fingerprint chip package structure 30 can be quickly loaded into the accommodating hole 212 .

The accommodating hole 212 and the supporting edge 22 can be formed by removing material on the parts by cutting, or can be formed by casting or the like.

In order to ensure the strength of the decorative ring 20 , preferably, the material of the decorative ring 20 is metal, such as stainless steel, so as to meet the strength requirement of the decorative ring 20 , and also has corrosion resistance, which improves the service life of the decorative ring 20 . Of course, the decorative ring 20 can also be made of other materials such as plastic.

In some embodiments, further, the fingerprint chip packaging structure 30 is accommodated in the decoration ring 21 and supported on the supporting edge 22 .

In some embodiments, the supporting edge 22 is perpendicular to the inner wall 211 of the decoration ring 21 .

In this way, the supporting edge 22 is easy to form, and the manufacturing cost of the decoration ring 21 can be reduced. In addition, when manufacturing the input assembly 100, the supporting edge 22 is positioned at a horizontal position, and the inner wall 211 of the decorative ring 21 is positioned at a vertical position, so that the surface of the fingerprint chip packaging structure 30 that cooperates with the supporting edge 22 is a horizontal plane, which can simplify the support on the supporting surface. The structure of the fingerprint chip packaging structure 30 on the side 22.

In some embodiments, the decoration ring 21 includes a first bottom surface 213 connected to the inner wall 211 , and the lower surface 221 of the supporting edge 22 is flush with the first bottom surface 213 .

In the decoration ring 21 of the same height, as above, a larger accommodation space can be formed in the decoration ring 21 to ensure that the fingerprint chip packaging structure 30 can be accommodated in the decoration ring 21 .

In other words, when the thickness of the fingerprint chip packaging structure 30 is constant, the height of the decoration ring 21 is small, so that the thickness of the input component 100 can be reduced, which can provide a design basis for the thickness reduction of the terminal 1000 .

In certain embodiments, the trim ring 21 includes a top wall 214 . The top wall 214 is connected to the inner wall 211 . The top wall 214 includes a guiding slope 2142 facing inwardly of the decoration ring 20 .

In this way, the guide inclined surface 2142 can guide the user's finger to smoothly enter the decoration ring 21 for fingerprint recognition operation, which can improve the accuracy of the user's fingerprint recognition operation. Further, a shiny metal layer (such as a chrome layer) can be plated on the guide slope 2142 to make the decoration ring 21 more beautiful.

It can be understood that the guide inclined surface 2142 is an annular surface, which is convenient for the user to insert fingers into the decoration ring 21 from various directions to press the fingerprint chip packaging structure 30 to perform fingerprint recognition operations.

In some embodiments, the supporting edge 22 is formed with an escape hole 222 .

In this way, the avoidance hole 222 is beneficial to the wiring layout of the fingerprint flexible circuit board 40 connected to the fingerprint chip packaging structure 30 . For example, the fingerprint flexible circuit board 40 can pass through the escape hole 222 to connect with the fingerprint chip packaging structure 30 (as shown in FIG. 2 ).

In some embodiments, the avoidance hole 222 is a rounded rectangle, and the sidewall 2221 of the avoidance hole 222 is formed with an avoidance groove 2222 along the axial direction of the avoidance hole 222 , and the avoidance groove 2222 communicates with the avoidance hole 222 .

For example, as shown in FIG. 2 , after the fingerprint flexible circuit board 40 is connected to the fingerprint chip packaging structure 30 , it first extends toward the escape groove 2222 , and then bends around. Therefore, the escape groove 2222 can prevent the fingerprint flexible circuit board 40 from interfering with the side wall 2221 , which is beneficial to the wiring of the fingerprint flexible circuit board 40 .

In some embodiments, the bezel 20 includes a flange 23 extending outward from the outer wall of the bezel 21 .

In this way, the flange 23 can abut against the lower surface 14 of the touch panel 10 , thereby increasing the connection area between the decoration ring 20 and the touch panel 10 , and improving the reliability of the fixed connection between the decoration ring 20 and the touch panel 10 .

In addition, when the decorative ring 20 is installed into the installation hole 17 from bottom to top, when the flange 23 abuts against the lower surface 14 of the touch panel 10 , it means that the decorative ring 20 has been installed to a predetermined position. Therefore, the arrangement of the flange 23 also improves the assembly efficiency of the input assembly 100 and reduces the manufacturing cost of the input assembly 100 .

In some embodiments, a sealing sheet may be provided between the flange 23 and the lower surface 14 to prevent water from entering the terminal 1000 from the gap between the decorative ring 20 and the mounting hole 17 , thereby improving the waterproof effect of the terminal 1000 .

In the embodiment shown in FIGS. 3-5 , the flange 23 and the decorative ring 21 are integrally formed. In the embodiment shown in FIG. 6 and FIG. 7 , the flange 23 and the decorative ring 21 are formed separately. Specifically, the decoration ring 21 includes a socket portion 24 , and the socket portion 24 is connected to the supporting edge 22 . The flange 23 is sleeved on the sleeve portion 24 . The separate molding of the flange 23 and the decorative ring 21 can reduce the manufacturing difficulty of the decorative ring 20 , so that the consistency of each decorative ring 20 can be improved when the decorative ring 20 is produced in batches.

It should be pointed out that, in some embodiments, the socket portion 24 may be provided with a via hole 24a for the fingerprint flexible circuit board 40 to pass through.

Specifically, the socket portion 24 includes a connecting edge 241 and a supporting plate 242 . The connecting edge 241 connects the supporting edge 22 and the supporting plate 242 , and the connecting edge 241 is substantially perpendicular to the supporting edge 22 . The supporting board 242 is substantially perpendicular to the connecting edge 241 . The connecting edge 241 defines a via hole 24a.

The socket portion 24 is hollow to accommodate part or all of the fingerprint chip packaging structure 30 . It should be noted that, in some implementations, the fingerprint chip packaging structure 30 may be supported on the carrier board 242 .

Referring to FIGS. 3-5 again, in some embodiments, the flange 23 is perpendicular to the outer wall 215 of the decoration ring 21 .

In this way, the manufacturing process of the decorative ring 20 is simple, and the contact area connected with the touch panel 10 can also be increased.

In some embodiments, the flange 23 includes a first convex portion 231 and a second convex portion 232 connected to the first convex portion 231, the first convex portion 231 includes a first portion 2311 and a second portion 2312, and the second portion 2312 The first portion 2311 and the second protruding portion 232 are connected, and the second portion 2312 protrudes from the first portion 2311 and the second protruding portion 232 .

After the decorative ring 20 is installed in the installation hole 17 , the first portion 2311 and the second convex portion 232 extend along the longitudinal direction of the touch panel 10 , and the second portion 2312 extends along the transverse direction of the touch panel 10 .

Since the accommodating space in the lateral direction of the touch panel 10 is large, the second portion 2312 protrudes from the first portion 2311 and the second convex portion 232 to increase the connecting area between the flange 23 and the touch panel 10 .

In addition, the width of the first portion 2311 and the second convex portion 232 is small, which can prevent the vertical length of the non-display area 16 of the touch panel 10 from being lengthened due to the width of the first portion 2311 and the second convex portion 232, thereby reducing the display area. The ratio of the area of 15 to the area of the touch panel 10 further affects the appearance of the terminal 1000 .

In some embodiments, the top surface 231 a of the first convex portion 231 is flush with the top surface 232 a of the second convex portion 232 , and the thickness of the first portion 2311 is greater than the thickness of the second convex portion 232 .

It can be understood that after the decorative ring 20 is installed in the installation hole 17 , the second convex portion 232 is closer to the display area 15 than the first portion 2311 . In other words, the first portion 2311 is disposed away from the display area 15 , and the second convex portion 232 is disposed close to the display area 15 .

Since there are many parts of the input assembly 100 near the display area 15, the thinner thickness of the second convex portion 232 can prevent the second convex portion 232 from interfering with other parts near the display area 15 (as shown in FIG. 2 ). .

As shown in FIG. 2 , the orthographic projection of the decoration ring 20 and the screen flexible circuit board 50 connected to the screen of the terminal 1000 and other components on the lower surface 14 of the touch panel 10 overlaps, and the thickness of the second convex portion 232 is relatively thin. Interference with the screen flexible circuit board 50 and other parts can be avoided, so that the decorative ring 20 can be arranged closer to the display area 15, and the decorative ring 20 can even be partially or completely arranged in the display area 15 of the touch panel 10 to reduce non-display The ratio of the area of the area 16 to the area of the touch panel 10 increases the ratio of the area of the display area 15 to the area of the touch panel 10 .

In some embodiments, the decorative ring 21 is oblong, and the outer wall 215 of the decorative ring 21 includes two parallel straight sections 2151 and two curved sections 2152 connecting the two straight sections 2151, and the first part 2311 is disposed therein. On one straight segment 2151 , the second portion 2312 is disposed on two curved segments 2152 .

In this way, the decorative ring 21 is more beautiful. Specifically, the two curved sections 2152 are arranged along the transverse direction of the touch panel 10 (left-right direction in FIG. 1 ), and the two straight sections 2151 are arranged along the longitudinal direction of the touch panel 10 (perpendicular to the transverse direction).

In some embodiments, the second portion 2312 is shaped to match the shape of the curved section 2152 .

For example, the outer contour of the second portion 2312 is also arc-shaped, and is substantially concentric with the curved section 2152 . This can make the structure of the decorative ring 20 more compact.

Please refer to FIGS. 8-10 together. In some embodiments, the fingerprint chip package structure 30 includes a package body 31 and a fingerprint identification chip 32 .

The package body 31 includes a second bottom surface 311 and a side surface 312 connected to the second bottom surface 311 , and a concave portion 33 is formed at the junction of the second bottom surface 311 and the side surface 312 . The fingerprint recognition chip 32 is arranged in the package body 31 .

In the fingerprint chip packaging structure 30 of the embodiment of the present utility model, the recessed part 33 can cooperate with the supporting edge 22 in the decoration ring 20, so that the fingerprint chip packaging structure 30 can be positioned, thereby improving the assembly efficiency of the fingerprint chip packaging structure 30.

In addition, the cooperation between the recessed portion 33 and the supporting edge 22 can also reduce the thickness of the fingerprint chip packaging structure 30 , which is beneficial to the miniaturization of the terminal 1000 using the fingerprint chip packaging structure 30 .

Specifically, when the user operates the fingerprint unlocking terminal 1000 , the user may place a finger on a position corresponding to the fingerprint identification chip 32 . The signal of the fingerprint recognition chip 32 passes through the package body 31 to collect and identify the user's fingerprint pattern, and the user's fingerprint pattern is matched with the pre-stored fingerprint pattern, and if the matching is successful, the terminal 1000 is unlocked.

It can be understood that the surface of the fingerprint recognition chip 32 facing the user's finger is provided with a sensing pixel array to collect the user's fingerprint pattern. Encapsulating the fingerprint identification chip 32 in the package body 31 can reduce the influence of other interference signals on the sensing pixel array when collecting fingerprint patterns, so as to improve the accuracy of identification.

It should be noted that the recessed portion 33 is used to cooperate with the supporting edge 22 so that the fingerprint chip packaging structure 30 is supported on the supporting edge 22 through the recessed portion 33 .

The recessed portion 33 cooperates with the supporting edge 33 , that is to say, the supporting edge 22 is accommodated in the recessed portion 33 .

In this embodiment, the recessed portion 33 has an annular structure, and correspondingly, the supporting edge 22 also has an annular structure so that the recessed portion 33 can accommodate the supporting edge 22 .

In other embodiments, the recessed portion 33 may be a plurality of recessed portions 33 arranged circumferentially at intervals around the junction of the second bottom surface 311 and the side surface 312, and correspondingly, the supporting edge 22 is also a plurality of supports arranged at intervals around the circumferential direction. On the side 22 , a plurality of recessed parts 33 are correspondingly matched with a plurality of supporting sides 22 .

For example, there are three depressions 33, two adjacent depressions 33 are arranged at intervals of 120 degrees around the circumference, and the number of supporting sides 22 is also three, corresponding to the three depressions in terms of structural position.

It should be pointed out that the shape and quantity of the recessed portion 33 are not limited to the situation discussed above, as long as the recessed portion 33 cooperates with the supporting edge 22 so that the supporting edge 22 can support the fingerprint chip packaging structure 30. Therefore, the above-mentioned example It should not be understood as a limitation of the present utility model.

Certainly, in other implementation manners, when the thickness of the fingerprint chip packaging structure 30 is relatively thin, the fingerprint chip packaging structure 30 may also omit the concave portion 33 .

In some embodiments, the package body 31 includes a first package part 313 and a second package part 314 connected to the first package part 313 , the first package part 313 includes a second bottom surface 311 , and the second package part 314 includes a side surface 312 .

In this way, the first encapsulation part 313 is connected to the second encapsulation part 314 to form the recessed part 33 . The package body 31 can be formed by cutting off the material on the package body 31 to form the recessed part 33 , or can be formed by connecting the first package part 313 and the second package part 314 .

It can be understood that, in order to form the concave portion 33 , the cross-sectional area of the first encapsulation portion 313 is smaller than the cross-sectional area of the second encapsulation portion 314 .

In some embodiments, the first packaging part 313 is disposed in the escape hole 222 , and the second packaging part 314 is supported on the supporting edge 22 .

In some implementations, the fingerprint identification chip 32 is disposed in the first packaging part 313 .

In this way, the circuit contacts of the fingerprint recognition chip 32 are easily exposed for connection with the fingerprint flexible circuit board 40 .

In some embodiments, the shape and size of the first packaging part 313 match the shape and size of the fingerprint recognition chip 32 .

In other words, the shape of the fingerprint identification chip 32 is similar or identical to that of the first packaging part 313 , for example, the fingerprint identification chip 32 is in the shape of a cuboid, and the shape of the first packaging part 313 is in the shape of a cuboid or a rounded cuboid.

The size of the first packaging part 313 is slightly larger than that of the fingerprint recognition chip 32 to achieve the effect of packaging the fingerprint recognition chip 32 . Therefore, this can make the structure of the fingerprint chip packaging structure 30 more compact.

In some implementations, the shape of the first encapsulating portion 313 is a rectangular parallelepiped with rounded corners.

In this way, the first package body 31 and the fingerprint recognition chip 32 can cooperate well. Further, the shape of the first encapsulating portion 313 matches the shape of the avoidance hole 222 , that is, the shape of the escape hole 222 is also a rounded cuboid.

In some embodiments, the second packaging part 314 includes a top surface 3141 connected to the side surface 312 , and the fingerprint chip packaging structure 30 includes a cover plate 34 fixed on the top surface 3141 of the second packaging part 314 . For example, the cover plate 34 is fixed on the top surface 3141 of the second packaging part 314 by glue.

The user may press the cover plate 34 with a finger when performing a fingerprint recognition operation. The cover plate 34 can protect the packaging body 31 from damage, so as to improve the reliability of the fingerprint chip packaging structure 30 .

Since the cover plate 34 is often touched, the cover plate 34 can be made of a material with higher hardness, such as the sapphire material mentioned above.

In some embodiments, the shape and size of the cover plate 34 match the shape and size of the top surface 3141 of the second packaging portion 314 .
