Referring to fig. 1 and 2, a structure of a screen assembly 100 according to a preferred embodiment of the present invention is shown. In this embodiment, the screen assembly 100 includes:
screen 110
The screen 110, which is the outermost facing component of the screen assembly 100, has an outwardly facing display area and an inwardly facing light transmissive laminating area of the screen 110. On the external device, such as a smart phone, 200, with the screen 110 installed, an interface may be displayed through the display area for viewing or manipulation by the user.
Screen wiring board 120
The screen circuit board 120 may also be called a main FPC, and is flexible, and has a small thickness, and is attached to the back surface of the screen 110, i.e., the user cannot observe the screen circuit board 120 on the front surface.
The screen wiring board 120 may have a longer length that extends along the length of the screen 110, which would require all of the other components displayed by the screen 110 to be electrically connected.
Fingerprint recognition module 130
In order to realize the recognition of the finger print after the user places the finger on the screen 110, the fingerprint recognition module 130 is disposed under the display area of the screen 110 and electrically connected with the screen circuit board 120, so that the recognition result of the fingerprint recognition is displayed in the display area.
To ensure overall space utilization under the screen 110, the screen assembly 100 additionally includes:
-a fixed bracket 140
A fixing bracket 140 is attached to the inner side of the screen 110, i.e., the back side thereof which is not used for displaying the display area. The fixing bracket 140 may have a size comparable to that of the screen 110, i.e., substantially covers the rear surface of the screen 110, and is flatly attached to the rear surface of the screen 110, and substantially no gap is generated between the fixing bracket and the rear surface of the screen 110. The fixing support 140 may be disposed between the display transparent layer and the buffer foam of the screen 110.
The fixing bracket 140 is further provided with a protrusion 141 for accommodating the fingerprint recognition module 130. Specifically, the fixing bracket 140 has a fixing end surface 142, the fixing end surface 142 is a surface that is not attached to the back surface of the screen 110, that is, the fixing end surface 142 is visible, the protrusion 141 protrudes from the fixing end surface 142 toward a direction away from the screen 110, or a certain portion of the fixing end surface 142 extends toward a direction away from the screen 110, and due to the protrusion, the protrusion 141 and the screen 110 form a mounting space, and the mounting space is used as an interior of the protrusion 141 for accommodating the fingerprint recognition module 130. Therefore, it can be appreciated that in order to reduce the thickness of the screen assembly 100 as much as possible, the protrusion height of the protrusion 141 may be comparable to the thickness of the fingerprint recognition module 130.
In the embodiment in which the protruding portion 141 protrudes from the fixing end surface 142, a portion of the body (not shown) of the fixing bracket 140 may be provided at a position where the protruding portion 141 protrudes, that is, a position where the protruding portion 141 is provided on the fixing bracket 140 may have a double-layered structure. In the embodiment where the fixing end surface 142 itself is formed to extend outward, the protrusion 141 and the screen 110 are not provided with the fixing bracket 140. Both of the above-described protruding modes may be implemented.
By the arrangement of the protruding portion 141, the protruding portion 141 supports the fingerprint recognition module 130 in a manner that the display area of the screen 110 faces the front outside, and the fingerprint recognition module 130 is limited in the installation space.
Flexible circuit board module
In addition to the fingerprint recognition module 130 being electrically connected to the screen circuit board 120 to display the fingerprint recognition result on the screen 110, the intelligent terminal 200 having the screen assembly 100 will also display other display contents such as text, video, animation, etc. through the screen 110, so that the integrated fingerprint recognition module can be integrated through a flexible circuit board module and then electrically connected to the screen circuit board 120, and further displayed on the screen 110.
The flexible circuit board module is attached to the fixed end surface 142, i.e. the fixed end surface 142 is used as a part of the fixed bracket 140 and is clamped between the screen 110 and the flexible circuit board module. Meanwhile, the flexible circuit board film group covers the protruding portion 141, and the fingerprint identification module 130 is further limited in the installation space.
Through the above configuration and the close fitting of the components, the thickness of the screen assembly 100 in this embodiment is substantially equal to the thickness of the screen assembly 100 in the embodiment in which the fingerprint recognition module 130 is externally arranged, so that the original holding feeling of the user holding the intelligent terminal 200 with the screen assembly 100 is maintained.
Since the protrusions 141 are provided for supporting the fingerprint recognition module 130, the structure thereof can be variously provided according to different requirements of the screen assembly 100.
Embodiment one of the protrusion 141
Referring to fig. 1 and 2, in this embodiment, the portion of the fixing bracket 140 attached to the screen 110 is a fixing end surface 142, which is visible outwards, while the protruding portion 141 is far from the screen 110, and the protruding end surface facing outwards is a protruding end surface 146. On the protruding end face 146, a notch 143 is opened, and the notch 143 extends in the lateral direction and is stopped at both end edges of the protruding end face 146. It will be appreciated that in this embodiment, the two end edges are still located at the outermost sides of the protruding portion 141, i.e. the protruding end surface 146 is provided with a notch 143 similar to a small opening for the fingerprint recognition module 130 to be placed therein. Naturally, alternatively, two openings may be formed on two sides of the protrusion 141 in the transverse direction, and the openings may be also communicated with the notch 143 to form a notch 143 with a U-shaped notch, so that when the fingerprint identification module 130 is placed, the fingerprint identification module 130 is supported by two edges through alternative insertion, so that the weight of the fixing bracket 140 is saved, and meanwhile, the fingerprint identification module 130 is in a semi-closed state to prevent overheating.
It will be appreciated that the slot 143 is not limited to one, and may be in the form of a louvered, spaced slot, partially slotted, staggered slot, etc., and is not limited to the manner described above.
Further, the notch 143 is opened along the longitudinal direction of the protrusion 141, and the entire fixing bracket 140 is divided into a first bracket unit 144 and a second bracket unit 145, that is, the first bracket unit 144 and the second bracket unit 145 are provided on both sides of the notch 143, and the protrusion shape of the protrusion 141 is formed by the self-structures of the first bracket unit 144 and the second bracket unit 145. Specifically, the present invention relates to a method for manufacturing a semiconductor device. The first bracket unit 144 and the second bracket unit 145 each have an extension strip 147, one end of the extension strip 147 is connected to the fixed end surface 142, the other end is connected to the mounting end surface, and the protrusion 141 is formed by the outward extension of the extension strip 147.
Second embodiment of the protrusion 141
In this embodiment, the fixing bracket 140 is not provided with a notch 143 on the protruding end surface 146, but is provided with openings (not shown) on both lateral sides of the protruding portion 141, and is fixed by laterally inserting the fingerprint recognition module 130. Compared with the first embodiment of the protrusion 141, the position limiting effect on the fingerprint recognition module 130 is better, but the installation is more complicated.
Regardless of the embodiment described above, the fingerprint recognition module 130 has an FPC that passes through the notch 143 or the opening and is connected to the main FPC to achieve electrical connection.
Based on the first embodiment of the protruding portion 141, the flexible circuit board module is matched with different structures of the fixing bracket 140 according to different arrangement requirements, so as to form different embodiments.
Example 1
Referring to fig. 3, in this embodiment, the flexible wiring board module includes:
flip chip film circuit board
The flip chip film wiring board, i.e., COF FPC151, is electrically connected to the screen wiring board 120. When the COF FPC151 is mounted, one end of the COF FPC151 is attached to the screen 110, and then folded at a substantially 90 ° right angle or rounded angle, and after being folded at a substantially 90 ° right angle or rounded angle to a height of a portion extending in a direction perpendicular to the screen 110 (which may be the same as the projection height of the projection 141), is folded at a substantially 90 ° right angle or rounded angle again to extend toward the projection 141, and the other end thereof extends along the contour of the fixing bracket 140 and is attached to the outside of the projection 141 as the COF FPC151 extends. Similar to the deposition of various materials, a tight stack of the screen 110-the fingerprint recognition module 130-the fixing bracket 140 (the protrusion 141) -the COF FPC151 is formed from the outside to the inside, and the fingerprint recognition module 130 is wrapped in the middle to secondarily limit the same.
Touch screen circuit board
The touch screen circuit board, i.e., the TP FPC152, is also electrically connected to the screen circuit board 120, which is disposed on one of the left and right sides of the fingerprint recognition module 130, and is layered with but does not substantially overlap the COF FPC 151. One end of the TP FPC152 is attached to the screen 110, and then turned at a substantially 90 ° right angle or rounded angle, and after extending to a height (which may be the same as the protrusion height of the protrusion 141) perpendicular to the screen 110, turned at a substantially 90 ° right angle or rounded angle again, and laid in a reverse direction.
The COF FPC151 and the TP FPC152 are both formed by thermocompression bonding with the screen wiring board 120, or the COF FPC151 and the screen wiring board 120 are integrated into one piece of FPC, with its flexible layout circuit.
The embodiment is suitable for the screen assembly 100 in which the fingerprint recognition module 130 is attached to one side of the screen 110, and since the fingerprint recognition module 130 is closer to one side of the screen 110, the length of the fixing end surface 142 on the first bracket unit 144 is smaller, and the portion between the COF FPC151 attached to the protruding end surface 146 after the second bending is smaller, the inner space formed by the excessive COF FPC151 during the two bending is not wasted.
Because of the two bends of the COF FPC151, the end attached to the screen 110 is U-shaped, and the end surface of the COF FPC151 far away from the screen 110 is substantially flush with the protruding end surface 146, or is slightly higher, the surface of the COF FPC151 attached to the protruding end surface 146 is substantially parallel to the screen 110.
On this basis, when components such as the connection board 160, the interface component IO170, the Speaker, the motor, etc. are further required to be mounted in the screen assembly 100, the connection board 160, the interface component IO170, the Speaker, the motor are disposed opposite to the outer side of the protrusion 141, and all the other side spaces of the protrusion 141 are staggered, and the other side spaces may be reserved for placing components such as a battery.
Example two
Referring to fig. 4, in this embodiment, the flexible wiring board module also includes: the COF 151 and the touch screen TP 152 are also bent twice, and the end of the COF 151 attached to the screen 110 is U-shaped, but unlike the first embodiment, in this embodiment, the fingerprint recognition module 130 is further away from the screen 110 than the first embodiment, so that the length of the fixed end surface 142 on the first support unit 144 is longer, and if the manner that the COF 151 extends in parallel after the second bending in the first embodiment is still used, the internal space formed by the excessive COF 151 during the second bending is wasted. Therefore, in the second embodiment, the end surface of the COF FPC151 away from the screen 110 is attached along the outline formed by the outer surfaces of the fixing end surface 142, the extension strips 147 and the protruding end surface 146, and is folded and laid at the folded position of the protruding portion 141, so that a part of the space of the fixing end surface 142 facing the outside is reserved as much as possible.
In addition, in the above configuration, the screen assembly 100 further includes the staggered protrusion 141, which is directly disposed at a portion of the COF FPC151 that does not extend along the protrusion 141, that is, is laid on the outer surface of the portion of the fixed end face 142, which saves more space than the first embodiment, and the interface assembly is more centered and conforms to the use habit of the user.
In the first and second embodiments, the screen assembly 100 further includes the screen driving chip IC180, and since there is no space left between the COF FPC151 and the fixing frame 140, the screen driving chip IC180 is attached to the end surface of the COF FPC151 away from the screen 110.
Example III
Referring to fig. 5, unlike the second embodiment, the fingerprint recognition module 130 is located closer to the middle of the screen 110, so that the fixing end surface 142 of the first bracket unit 144 is longer in the length direction, and the COF FPC151 is cut off on the outer side of the protruding end surface 146 when it is extended and cut off, that is, unlike the first embodiment and the second embodiment, the protruding portion 141 is not completely covered, and at this time, if it is required to ensure the electrical connection between the COF FOC and the screen circuit board 120, that is, the main FPC will be disposed on the outer side of the COF FPC151, that is, the COF FPC151 is thermally pressed between the protruding end surface 146 and the main FPC.
And further, when the screen assembly 100 further includes the screen driving chip IC180, the fixing bracket 140 is slotted to avoid, so that the screen driving chip IC180 can be attached to the end surface of the COF FPC151 near the screen 110, that is, the inner side of the COF FPC151, and the protection effect on the driving chip IC is better.
In the above three different embodiments, according to different requirements of different users on the setting positions of the fingerprint identification module 130, by different lamination modes, not only is no additional usage space ensured to be added, but also the perfect limit of the fingerprint identification module 130 is realized. In addition, the fixing bracket 140 used in the embodiments may be made of metal, and the service life is longer.
After the screen assembly 100 is provided, referring to fig. 6, the screen assembly 100 may be applied to a smart terminal 200 such as a smart phone and a tablet computer, and when the smart terminal 200 is installed, a housing 210 forming an external profile of the smart terminal 200 is first obtained, and the screen assembly 100 is put in, and a battery assembly 220 is installed, and the battery assembly 220 cooperates with a portion of the screen assembly 100 and the housing 210 to clamp and fix the position of the screen assembly 100.
