As illustrated in
The input assembly 100 according to embodiments of the present disclosure can be applied to a terminal 1000, and the terminal 1000 can be configured as an electronic device such as a mobile phone or a tablet. It can be understood that, the terminal 1000 includes but is not limited to examples in the present embodiment. In some embodiments, the terminal 1000 further includes a screen 80 configured to display content and a flexible screen circuit board 50 coupled to the screen 80.
In some embodiments, the touch panel 10 is located above the screen 80, and includes an upper surface 12 and a lower surface 14, as illustrated in
The touch panel 10 can be made of light-transparent materials, such as glasses, ceramics or sapphires. As the touch panel 10 is configured as an input part of the terminal 1000, the touch panel 10 always suffers contacts, such as impacts or scratches. For example, when the user puts the terminal 1000 into his/her pocket, the touch panel 10 can be scratched and damaged by keys in the pocket of the user.
Therefore, the touch panel 10 can be made of materials having high hardness, for example the above-mentioned sapphires. Certainly, a protecting cover plate can be attached on the upper surface 12 of the touch panel 10, so as to prevent the touch panel 10 from being scratched.
Furthermore, the touch panel 10 includes a display region 15 intended for the user to view the content displayed in the screen 80 and a non-display region 16 for receiving the fingerprint identification structure. In general, a middle region of the touch panel 10 is configured as the display region 15, and the non-display region 16 is arranged at a periphery of the display region 15. For example, the non-display region 16 is located at a top side or a bottom side of the display region 15.
As the touch panel 10 is made of the light-transparent materials, thus, the user can view content displayed in the screen 80 of the terminal 1000 through the display region 15.
For allowing the terminal 1000 to have a better appearance, ink can be sprayed on a lower surface 14 of the non-display region 16. The ink can have a color such as white, black or blue, and so on. A specific color can be set according to actual requirements. The ink can not only satisfy requirements of the user for terminals 1000 having various colors, but also shield structures inside the terminal 1000 so as to reach an effect of beautifying the terminal 1000.
In some embodiments, a shape of the touch panel 10 can be designed specifically according to a shape of the terminal 1000, for example being configured as a rounded rectangle.
Furthermore, the touch panel 10 has a mounting hole 17. In the present embodiment, the mounting hole 17 is configured as a through hole running through the upper surface 12 and the lower surface 14. In other embodiments, the mounting hole 17 can be configured a blind hole formed in the lower surface 14.
In the present embodiment, the mounting hole 17 is configured to have a long circle shape. Certainly, in other embodiments, the mounting hole 17 can have various shapes according to specific requirements, for example a round or oval shape. Therefore, examples of the shape of the mounting hole 17 in the present embodiment cannot be construed to limit the present disclosure.
In some embodiments, the decoration enclosure 20 is fitted in the mounting hole 17 and fixedly coupled to the touch panel 10. The fingerprint chip package structure 30 is accommodated in the decoration enclosure 20 and fixedly coupled to the decoration enclosure 20.
In general, a receiver of the terminal 1000 is disposed in a top region of the terminal 1000. Therefore, for preventing the mounting hole 17 from having an interference with the receiver, in some embodiments, the mounting hole 17 is provided in a bottom region of the touch panel 10, thereby providing a relatively large design space for the mounting hole 17. Furthermore, the mounting hole 17 is provided in the non-display region 16 of the touch panel 10.
In some embodiments, the mounting hole 17 is defined in the middle of the bottom region of the touch panel 10, so that the touch panel 10 presents an approximately symmetrical structure. Thus, the terminal 1000 has a better appearance and is easy to be operated by the user.
When the mounting hole 17 is configured as the through hole, during manufacture of the input assembly 100, the decoration enclosure 20 can be mounted into the mounting hole 17 from underneath of the touch panel 10 firstly, and then an adhesive is dispensed in a gap between an inner wall of the mounting hole 17 and the decoration enclosure 20, so that the decoration enclosure 20 is fixedly coupled to the touch panel 10.
Subsequently, the fingerprint chip package structure 30 is mounted into the decoration enclosure 20 from above of the touch panel 10, and the fingerprint chip package structure 30 is fixedly coupled to the decoration enclosure 20 through the adhesive.
When the mounting hole 17 is configured as the blind hole, the fingerprint chip package structure 30 can be mounted into the decoration enclosure 20 firstly, then the decoration enclosure 20 carried with the fingerprint chip package structure 30 can be mounted into the mounting hole 17, and the adhesive can be used to adhere and fix the decoration enclosure 20 to the touch panel 10.
As illustrated in
The support rim 22 of the decoration enclosure 20 according to embodiments of the present disclosure can support and position the fingerprint chip package structure 30, thereby improving an assembling efficiency of the fingerprint chip package structure 30 and the decoration enclosure 20.
That is to say, the fingerprint chip package structure 30 is supported on the support rim 22. When the fingerprint chip package structure 30 is mounted into the decoration ring 21, the fingerprint chip package structure 30 can be pressed from top to down. If the fingerprint chip package structure 30 cannot be moved any more, it indicates that the fingerprint chip package structure 30 abuts against the support rim 22 and is mounted to a preset location.
In some embodiments, the decoration ring 21 defines an accommodating hole 212, and the support rim 22 is located in the accommodating hole 212. The accommodating hole 212 can be configured to have a straight cylinder shape, or that is to say, the inner wall 211 is configured to be straight, so that the fingerprint chip package structure 30 is easy to be mounted in the accommodating hole 212 rapidly.
The accommodating hole 212 and the support rim 22 can be formed by removing materials from the parts through cutting process, or can be formed by casting.
For ensuring the strength of the decoration enclosure 20, in some embodiments, materials of the decoration enclosure 20 can be metal, for example stainless steel materials, thereby satisfying strength requirements of the decoration enclosure 20 as well as providing a corrosion resistance and improving a service life of the decoration enclosure 20. Certainly, the decoration enclosure 20 can also be made of other materials, such as plastics.
In some embodiments, furthermore, the fingerprint chip package structure 30 is accommodated in the decoration ring 21 and supported on the support rim 22.
In some embodiments, the support rim 22 is perpendicular to the inner wall 211 of the decoration ring 21.
Thus, the support rim 22 is easy to be formed, thereby reducing a production cost of the decoration ring 21. In addition, when the input assembly 100 is manufactured, the support rim 22 is located in a horizontal position, and the inner wall 211 of the decoration ring 21 is located in a vertical position, so that a surface of the fingerprint chip package structure 30 fitted with the support rim 22 is a horizontal surface, thereby simplifying a structure of the fingerprint chip package structure 30 supported on the support rim 22.
In some embodiments, the decoration ring 21 includes a first bottom surface 213 connected to the inner wall 211, and a lower surface 221 of the support rim 22 is flush with the first bottom surface 213.
Among the decoration rings 21 having a same height, the decoration ring 21 having an arrangement described above has a relatively large accommodating space, so as to ensure that the fingerprint chip package structure 30 can be accommodated in the decoration ring 21.
Or, that is to say, in the case that the fingerprint chip package structure 30 has a constant thickness, a height of the decoration ring 21 is relatively small, thus reducing a height of the input assembly 100, thereby providing a design basis for reducing a thickness of the terminal 1000.
In some embodiments, the decoration 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 surface 2142 facing towards an interior of the decoration enclosure 20.
In this way, the guiding surface 2142 can guide a finger of the user to enter the decoration ring 21 smoothly, so as to perform fingerprint identification operations, thereby improving an accuracy of the user performing the fingerprint identification operations. Furthermore, the guiding surface 2142 can be coated with a shiny metal layer (such as a chromium layer), so that the decoration ring 21 has a better appearance.
In some embodiments, the guiding surface 2142 can be configured as an annular surface, thereby facilitating the user to place the finger thereof in the decoration ring 21 from respective directions, so as to press the fingerprint chip package structure 30 and perform the fingerprint identification operations.
In some embodiments, the support rim 22 has a hole 222 therein.
Thus, the hole 222 contributes to a routing layout of a flexible fingerprint circuit board 40 coupled to the fingerprint chip package structure 30. For example, the flexible fingerprint circuit board 40 can run through the hole 222 so as to be coupled to the fingerprint chip package structure 30 (as illustrated in
In some embodiments, the hole 222 is configured to have a rounded rectangle shape. A side wall 2221 surrounding the hole 222 has a groove 2222 along an axial direction (i.e. a left-right direction illustrated in
For example, as illustrated in
In some embodiments, the decoration enclosure 20 includes a flange 23 extending outwards from an outer wall 215 of the decoration ring 21.
Thus, the flange 23 can abut against the lower surface 14 of the touch panel 10, thereby increasing a connecting area between the decoration enclosure 20 and the touch panel 10, and improving the reliability of fixedly connecting the decoration enclosure 20 with the touch panel 10.
In addition, when the decoration enclosure 20 is mounted into the mounting hole 17 from bottom to top, if the flange 23 abuts against the lower surface 14 of the touch panel 10, it indicates that the decoration enclosure 20 is mounted to a preset position. Therefore, the flange 23 is provided to improve the assembling efficiency of the input assembly 100 and to reduce the production cost of the input assembly 100.
In some embodiments, a sealing sheet can be provided between the flange 23 and the lower surface 14, so as to prevent water from entering the terminal 1000 through a gap between the decoration enclosure 20 and the mounting hole 17, thereby improving a water resistance effect of the terminal 1000.
In embodiments illustrated in
In some embodiments, the muff-coupling portion 24 can have a through hole 24a through which the flexible fingerprint circuit board 40 can run.
In some embodiments of the present disclosure, the muff-coupling portion 24 includes a connecting rim 241 and a bearing plate 242. The connecting rim 241 is connected to the support rim 22 and the bearing plate 242. The connecting rim 241 is substantially perpendicular to the support rim 22. The bearing plate 242 is substantially perpendicular to the connecting rim 241. The connecting rim 241 has the through hole 24a therein.
The muff-coupling portion 24 is hollow so as to accommodate a part or a whole of the fingerprint chip package structure 30. In some embodiments, the fingerprint chip package structure 30 can be supported on the bearing plate 242.
As illustrated in
Thus, the manufacturing process of the decoration enclosure 20 is easy, and a contact area of the decoration enclosure 20 and the touch panel 10 can also be improved, in which the contact area is used for connection between the decoration enclosure 20 and the touch panel 10.
In some embodiments, the flange 23 includes a first protrusion 231 and a second protrusion 232 coupled to the first protrusion 231. The first protrusion 231 includes a first portion 2311 and a second portion 2312. The second portion 2312 is coupled to the first portion 2311 and the second protrusion 232. The second portion 2312 protrudes beyond the first portion 2311 and the second protrusion 232, that is, an outer edge of the second portion 2312 has a larger distance from the outer wall 215 of the decoration ring 21 than outer edges of the first portion 2311 and the second protrusion 232.
After the decoration enclosure 20 is mounted in the mounting hole 17, the first portion 2311 and the second protrusion 232 extend along a traverse direction of the touch panel 10 and the second portion 2312 extends along a longitudinal direction of the touch panel 10.
As the non-display region 16 has a relatively large arrangement space in the traverse direction, the second portion 2312 can protrude beyond the first portion 2311 and the second protrusion 232, so as to increase a connecting area of the flange 23 and the touch panel 10.
In addition, widths of the first portion 2311 and the second protrusion 232 are relatively small, thereby avoiding a longitudinal size of the non-display region 16 of the touch panel 10 from being increased due to the widths of the first portion 2311 and the second protrusion 232, such that an area ratio of the display region 15 to the touch panel 10 will not be reduced, and thus the appearance of the terminal 1000 will not be affected.
In some embodiments, a top surface 231a of the first protrusion 231 is flush with a top surface 232a of the second protrusion 232, and a thickness of the first portion 2311 is larger than a thickness of the second protrusion 232.
In some embodiments, when the decoration enclosure 20 is mounted in the mounting hole 17, the second protrusion 232 is closer to the display region 15, compared to the first portion 2311. Or, that is to say, the first portion 2311 is away from the display region 15, and the second protrusion 232 is close to the display region 15.
As there are more parts in a portion of the input assembly 100 close to the display region 15, the second protrusion 232 will not have an interference with other parts close to the display region 15 due to the small thickness of the second protrusion 232 (as illustrated in
As illustrated in
In some embodiments, the orthographic projection of the decoration enclosure 20 in the lower surface 14 of the touch panel 10 may completely overlap the orthographic projection of the flexible screen circuit board 50 in the lower surface 14 of the touch panel 10, but the present disclosure is not limited to this. For example, in other embodiments, the orthographic projection of the decoration enclosure 20 in the lower surface 14 of the touch panel 10 may partially overlap the orthographic projection of the flexible screen circuit board 50 in the lower surface 14 of the touch panel 10.
In some embodiments, the decoration ring 21 is configured to have a long circle shape. The outer wall 215 of the decoration ring 21 includes two straight segments 2151 in parallel and two curved segments 2152 each coupled to the two straight segments 2151. The first portion 2311 is provided to one of the two straight segments 2151, and the second portion 2312 is provided to each curved segment 2152. As illustrated in
Thus, the decoration ring 21 has the better appearance. In some embodiments of the present disclosure, the two curved segments 2152 are arrayed in two lines along the traverse direction (for example the left-right direction illustrated in
In some embodiments, a shape of the second portion 2312 is matched with a shape of the curved segment 2152.
For example, an outer contour of the second portion 2312 also has an arc shape, and the second portion 2312 and the curved segment 2152 are substantially concentrically arranged, so that the decoration enclosure 20 has a more compact structure.
As illustrated in
The package body 31 includes a second bottom surface 311 and a lateral surface 312 connected to the second bottom surface 311, and a recessed portion 33 is formed at a junction of the second bottom surface 311 and the lateral surface 312. The fingerprint identification chip 32 is received in the package body 31.
In the fingerprint chip package structure 30 according to embodiments of the present disclosure, the recessed portion 33 can be fitted with the support rim 22 of the decoration enclosure 20, thereby positioning the fingerprint chip package structure 30, and further improving the assembling efficiency of the fingerprint chip package structure 30.
In addition, since the recessed portion 33 is fitted with the support rim 22, a thickness of the fingerprint chip package structure 30 can be reduced, thus facilitating miniaturization of the terminal 1000 to which the fingerprint chip package structure 30 is applied.
In some embodiments, when the user performs an operation to unlock the terminal 1000 via a fingerprint, the finger can be put in a position corresponding to the fingerprint identification chip 32. A signal of the fingerprint identification chip 32 is transmitted through the package body 31 so as to collect and identify a fingerprint pattern of the user, and then the fingerprint pattern of the user is matched with a prestored fingerprint pattern. If the matching is successful, the terminal 1000 is unlocked.
In some embodiments, a surface of the fingerprint identification chip 32 facing towards the finger of the user is provided with a sensing pixel array, so as to collect the fingerprint pattern of the user. The package body 31 packages the fingerprint identification chip 32, so as to reduce influences of other interference signals on the sensing pixel array when the sensing pixel array collects the fingerprint pattern, thus improving an accuracy of the identification.
In some embodiments, the recessed portion 33 is configured to be fitted with the support rim 22, that is to say, the support rim 22 is configured to be accommodated in the recessed portion 33, so that the fingerprint chip package structure 30 is supported on the support rim 22 through the recessed portion 33.
In the present embodiment, the recessed portion 33 is configured to be annular. Correspondingly, the support rim 22 also is configured to be annular, so that the recessed portion 33 can accommodate the support rim 22.
In other embodiments, a plurality of recessed portions 33 spaced apart from one another along a circumferential direction of the junction of the second bottom surface 311 and the lateral surface 312 can be provided, and correspondingly, a plurality of support rims 22 spaced apart from one another along the circumferential direction can be also provided. The plurality of recessed portions 33 are fitted with the plurality of support rims 22 correspondingly.
For example, three recessed portions 33 can be provided, and two adjacent recessed portions 33 are spaced apart from each other by 120° along the circumferential direction. Three support rims 22 can also be provided, and the three support rims 22 are corresponding to the three recessed portions 33 with respect to the structural position.
In some embodiments, the shape and the number of the recessed portion 33 are not limited to the above-discussed cases, as long as the recessed portion 33 is fitted with the support rim 22, so that the support rim 22 can support the fingerprint chip package structure 30. Therefore, the above-mentioned examples cannot be construed to limit the present disclosure.
Certainly, in some embodiments, when the thickness of the fingerprint chip package structure 30 is relatively small, the recessed portion 33 can be omitted from the fingerprint chip package structure 30.
In some embodiments, the package body 31 includes a first package portion 313 and a second package portion 314 coupled to the first package portion 313. The first package portion 313 includes the second bottom surface 311, and the second package portion 314 includes the lateral surface 312.
Thus, the recessed portion 33 can be defined by the first package portion 313 and the second package portion 314. For example, the package body 31 can be provided with the recessed portion 33 by cutting off materials from the package body 31, i.e. via the cutting process, or the recessed portion 33 can also be directly formed together with the package body 31 by casting.
In some embodiments, for forming the recessed portion 33, a cross-section area of the first package portion 313 is smaller than a cross-section area of the second package portion 314.
In some embodiments, the first package portion 313 is received in the hole 222, and the second package portion 314 is supported on the support rim 22.
In some embodiments, the fingerprint identification chip 32 is received in the first package portion 313.
Thus, a circuit junction of the fingerprint identification chip 32 is easy to be exposed, so as to be coupled to the flexible fingerprint circuit board 40.
In some embodiments, a shape and a size of the first package portion 313 are matched with a shape and a size of the fingerprint identification chip 32.
Or, that is to say, the shape of the fingerprint identification chip 32 is similar to or same with the shape of the first package portion 313. For example, the fingerprint identification chip 32 is configured to have a cuboid shape and the first package portion 313 is configured to have a cuboid or a rounded cuboid shape.
The size of the first package portion 313 is slightly larger than the size of the fingerprint identification chip 32, so as to achieve an effect of packaging the fingerprint identification chip 32. Thus, the fingerprint chip package structure 30 has the more compact structure.
In some embodiments, the first package portion 313 has the rounded cuboid shape.
Thus, the package body 31 can be better fitted with the fingerprint identification chip 32. Furthermore, the shape of the first package portion 313 is matched with a shape of the hole 222, that is to say, the hole 222 also has the rounded cuboid shape.
In some embodiments, the second package portion 314 includes a top surface 3141 connected to the lateral surface 312. The fingerprint chip package structure 30 includes a cover plate 34 fixed on the top surface 3141 of the second package portion 314. For example, the cover plate 34 can be fixed on the top surface 3141 of the second package portion 314 through adhesive.
When the user performs the fingerprint identification operation, the finger can press on the cover plate 34. The cover plate 34 can protect the package body 31 from being damaged, so as to improve the reliability of the fingerprint chip package structure 30.
As the cover plate 34 suffers touches frequently, the cover plate 34 can be made of materials having high hardness, for example the sapphires materials mentioned above.
In some embodiments, a shape and a size of the cover plate 34 are matched with a shape and a size of the top surface 3141 of the second package portion 314.
For example, the top surface 3141 is configured to have a long circle shape, and the cover plate 34 is also configured to have a long circle shape. An area of the cover plate 34 is slightly larger than an area of the top surface 3141 of the second package portion 314. Thus, the cover plate 34 can cover the second package portion 314 entirely.
In some embodiments, a sealing member 60 is provided between the second package portion 314 and the support rim 22. The sealing member 60 is configured to seal a gap between the second package portion 314 and the support rim 22. For example, the sealing member 60 is made of silica gel (as illustrated in
Thus, the sealing member 60 can prevent foreign matters (such as water and dust) from entering the terminal 1000 from a gap between the fingerprint chip package structure 30 and the decoration enclosure 20, thereby improving the waterproof and dustproof effects of the terminal 1000.
In some embodiments, the recessed portion 33 includes a first surface 331 and a second surface 332 connected to the first surface 331, and the first surface 331 is perpendicular to the second surface 332.
Thus, the recessed portion 33 is easy to be formed, and the first surface 331 is easy to be connected to the support rim 22. The first surface 331 is perpendicular to the second surface 332, so that the package body 31 is configured to have a stepped shape.
In some embodiments, the sealing member 60 is between the first surface 331 and the support rim 22.
In some embodiments, a junction of the first surface 331 and the second surface 332 is configured to be a transition fillet.
Thus, defects (such as cracks) are not easy to occur at the junction of the first surface 331 and the second surface 332 and the recessed portion 33 is easy to be formed.
