Detailed Description
An embodiment of the present invention provides a display cover assembly, as shown in fig. 1, including a fingerprint identification module 20, a cover plate 10, and a bracket 30 disposed below the cover plate 10. Wherein, the cover plate 10 is provided with a mounting hole 101. The fingerprint identification module 20 is fixedly connected to the bracket 30 and is disposed through the mounting hole 101.
It should be noted that the aperture shape of the mounting hole 101 is not limited in the embodiment of the present invention. For example, as shown in fig. 2, the aperture shape of the mounting hole 101 is circular. Or, for another example, as shown in fig. 3, the aperture shape of the mounting hole 101 is rectangular. In this case, the shape of the fingerprint recognition module 20 in plan view may match the aperture shape of the mounting hole 101, that is, when the aperture shape of the mounting hole 101 is rectangular, the shape of the fingerprint recognition module 20 located in the mounting hole 101 in plan view is also rectangular. Other shapes of the mounting hole 101 openings are not described in detail herein.
Further, the cover plate 10 may be a glass cover plate or a sapphire cover plate.
On the basis, the fingerprint identification module 20 includes a front cover 201 and a fingerprint identifier 202 located on the lower surface of the front cover 201 (i.e. the non-touch surface B1 of the front cover 201) as shown in fig. 4.
It should be noted that the type of the fingerprint identifier 202 is not limited in the embodiment of the present invention, and for example, the fingerprint identifier may be a capacitive type fingerprint identifier, where a user generates different capacitances for the ridges and valleys of the finger and the electrodes in the fingerprint identifier 202 during the touch process to collect the fingerprint.
Alternatively, the fingerprint may be collected optically by reflecting different light rays from the ridges and valleys of the finger.
Or, it may be a radio frequency type, which emits a signal of a specific frequency by radio waves or ultrasonic waves, and receives reflected waves of the signal that are different on ridges and valleys to collect a fingerprint.
In this case, as shown in fig. 4, the mounting hole 101 includes a first through hole 1011, and a side surface of the front cover 201 contacts a side wall of the first through hole 1011.
On this basis, the longitudinal section of protecgulum 201 and first through-hole 1011 is down trapezoidal to make this first through-hole 1011's lateral wall can support the side of protecgulum 201, and then support whole fingerprint identification module 20 through this first through-hole 1011's lateral wall.
It should be noted that the trapezoid generally includes two bottom sides disposed oppositely, wherein the longer bottom side is the lower bottom, and the shorter bottom side is the upper bottom. Based on this, the inverted trapezoid means that the positions of the lower bottom and the upper bottom are interchanged, and at this time, the longer bottom side is on top, i.e. away from the fingerprint identifier 202; and the shorter base is down, i.e., near the fingerprint identifier 202.
In addition, the above-mentioned longitudinal section means that the cover plate 10 of the display cover plate assembly is parallel to the ground when the display cover plate assembly is placed parallel to the ground. The cross section of the front cover 201 and the first through hole 1011 taken in a direction perpendicular to the ground or the cover plate 10 is the longitudinal cross section.
Thus, the sidewall of the first through hole 1011 can bear a part of the weight of the fingerprint identification module 20, so that the pressure applied to the bracket 30 by the weight of the fingerprint identification module 20 can be reduced, and the bracket 30 is prevented from deforming at the position where the fingerprint identification module 20 is connected. In addition, the lateral wall of first through-hole 1011 can be injectd the position of fingerprint identification module 20 after the side contact with protecgulum 201, avoids this fingerprint identification module 20 to rock in mounting hole 101.
Further, the front cover 201 may be made of glass, ceramic, or sapphire. In order to facilitate easy recognition by the fingerprint recognizer 202, a white or colored coating may be applied to the edge area of the front cover 201.
However, when the front cover 201 and the cover plate 10 are both made of the above-described glass (or ceramic, or sapphire), the edge of the front cover 201 collides with the side wall of the first through hole 1011 during use and installation. Causing scratches on the edge of the front cover 201 or the side wall of the first through hole 1011.
Therefore, the probability of the scratch is reduced, and the fingerprint identifier 202 is easy to identify. Preferably, as shown in fig. 5, the front cover 201 includes a touch panel 2010 covering the fingerprint recognizer 202 and a decoration ring 2011 located around the touch panel 2010 and connected to the touch panel 2010.
The touch panel 2010 is used to protect the upper surface of the fingerprint identifier 202, and may be made of glass, ceramic, or sapphire having good wear resistance.
As shown in fig. 6, the decoration ring 2011 is used to decorate the periphery of the touch panel 2010, so that the fingerprint identifier 202 is located at a more obvious position, which is beneficial to user identification. In addition, the decorative ring 2011 can protect the edge of the touch panel 2010, so that the touch panel 2010 with a hard texture is prevented from being in direct contact with the side wall of the first through hole 1011, and the probability of the scratch phenomenon can be reduced.
In addition, since the metal material has good ductility and is favorable for molding, and the metal luster unique to the metal material has a good decorative effect, the material constituting the decorative ring 2011 may preferably be a metal material.
For this reason, the bezel 2011 may be connected to the touch panel 2010 by a snap-fit method. Alternatively, the decorative ring 2011 is bonded to the periphery of the touch panel 2010 by dispensing between the decorative ring 2011 and the contact surface of the touch panel 2010.
In this case, as shown in fig. 5, the touch panel 2010 has a rectangular longitudinal section. The longitudinal sections of the decorative rings 2011 are two triangles which are respectively positioned on two sides of the touch surface 2010 and are symmetrically arranged. Wherein the longitudinal section is perpendicular to the cover plate 10. The surface of the triangle where the bottom edge is located is the side surface of the front cover 201, and is used for contacting with the side wall of the first through hole 1011.
On this basis, in order to protect the side of the fingerprint identifier 202 from being damaged, it is preferable that, as shown in fig. 5, the cover plate 10 further includes a second through hole 1012, and at least a part of the fingerprint identifier 202 is located in the second through hole 1012. In this manner, the sides of the fingerprint identifier 202 may be protected by the sidewalls of the second through-hole 1012. In this case, as shown in fig. 7, the second through hole 1012 communicates with the first through hole 1011, and the touch panel 2010 and the bezel 2011 are located within the first through hole 1011 as shown in fig. 5.
Further, in order to avoid foreign substances in the external water vapor or the air, the gap between the decoration ring 2011 and the first through hole 1011 enters the display cover plate assembly, so that the fingerprint identifier 202 is affected. Preferably, as shown in FIG. 5, a seal 60 is disposed between the second through-hole 1012 and the fingerprint identifier 202. The seal ring 60 seals the gap between the second through hole 1012 and the fingerprint identifier 202, preventing moisture or impurities in the air from entering the inside of the display cover assembly.
On this basis, in order to fix the position of the fingerprint identification module 20, as shown in fig. 5, the middle portion of the bracket 30 is adhered to the surface of the fingerprint identifier 202 away from the front cover 201 through a dispensing process. In this case, a glue layer 50 formed by the above dispensing process is disposed between the fingerprint identifier 202 and the holder 30.
Because different types of fingerprinter 202 have different thicknesses, the required thickness of adhesive layer 50 will vary. The thickness of the above-mentioned adhesive layer 50 needs to be adjusted. At this time, preferably, as shown in fig. 5, a spacer 51 for adjusting the thickness of the adhesive layer is further provided between the fingerprint identifier 202 and the support 30. In order to avoid the influence of the arrangement of the spacer 51 on the glue layer 50, there is no overlapping area between the spacer 51 and the orthographic projection of the glue layer 50 on the bracket 30.
Preferably, the spacer 51 may be formed by stacking a plurality of foam pads. In this case, the number of the foam pads can be increased to adjust the distance between the fingerprint identifier 202 and the holder 30, and finally the thickness of the adhesive layer 50 can be adjusted.
It should be noted that, in the embodiment of the present invention, the number of the spacers 51 and the adhesive layers 50 is not limited, as long as the arrangement positions of the spacers 51 and the adhesive layers 50 are not overlapped.
On this basis, the fingerprint identification module 20 further includes a back cover 203 as shown in fig. 8, which is disposed on a side surface of the fingerprint identifier 202 facing away from the front cover 201. The back of the fingerprint identifier 202 is protected by a back cover 203. The fingerprint identifier 202 and the back cover 203 can be connected by a dispensing process.
In order to improve the adhesive strength of the adhesive layer 50, it is preferable that a plurality of concave portions be provided on the surface of the back cover 203 on the side away from the fingerprint recognizer 202 at positions corresponding to the adhesive layer 50, as shown in fig. 8.
At this time, the surface of the back cover 203 for contacting the adhesive layer 50 is uneven. So, through setting up above-mentioned unevenness's surface, can be at the in-process of gluing for liquid glue can enter into above-mentioned depressed part, thereby increased liquid glue and the area of contact that back lid 203 deviates from one side surface of fingerprint identification ware 202, and then improved the bonding strength of glue film 50.
Further, as shown in fig. 5 or 8, elastic support pads 40 contacting the cover plate 10 are respectively installed at both ends of the bracket 30. Under the supporting action of the elastic supporting pads 40, both ends of the bracket 30 are bent in a direction away from the cover plate 10, so that the bracket 30 has an arcuate shape. At the same time, under the supporting action of the elastic supporting pad 40, the touching surface a1 (shown in fig. 1) of the front cover 201 is lower than or flush with the touching surface a2 of the cover plate 10.
Specifically, one end of the elastic supporting pad 40 contacts the cover plate 10, and the other end is fixedly mounted on the bracket 30. The elasticity of the elastic support pad 40 enables the elastic support pad 40 to have a supporting function in the releasing process. At this time, the elastic support pad 40 applies an upward force to the cover plate 10, and since the cover plate 10 has a greater hardness than the elastic support pad 40, the cover plate 10 may generate a downward reaction force to the elastic support pad 40, and the reaction force is transmitted to the bracket 30 through the elastic support pad 40.
At the same time, the elastic support pad 40 also applies a downward force to the bracket 30, so that both ends of the bracket 30 are bent downward.
As can be seen from the above, the entire bracket 30 is subjected to the downward force exerted by the elastic support pad 40, and the downward force transmitted to the bracket 30 by the cover plate 10 through the elastic support pad 40.
In this case, the bracket 30 can pull down the fingerprint recognition module 20 fixedly connected therewith, so that the touch surface a1 (shown in fig. 1) of the front cover 201 is lower than or flush with the touch surface a2 of the cover plate 10. Therefore, the user can not be scratched by the edge of the front cover 201 of the fingerprint identification module 20 in the process of touching the fingerprint identification module 20.
As can be seen from the above, the downward force applied to the bracket 30 is partially used to deform the two ends of the bracket 30, and the other part is used to pull the fingerprint identification module 20 to displace downward. In this case, the holder 30 may be, for example, a metal sheet having a thickness of 0.1 to 0.3mm, preferably 0.2 mm. In this way, the holder 30 made of a metal material can have a certain rigidity, and the fingerprint recognition module 20 can be pulled downward. In addition, the metal sheet having a certain thickness has a certain flexibility, so that both ends thereof can be deformed under the supporting action of the elastic supporting pad 40.
The elastic support pad 40 is a member having elasticity, such as a spring; or an elastic resin such as rubber.
In addition, in the embodiments of the present invention, the directional terms "upper" and "lower" are defined with respect to the schematically-disposed orientation of the display cover assembly in the drawings, and it is to be understood that these directional terms are relative concepts, which are used for descriptive and clarifying purposes, and may be changed accordingly according to the change of the orientation in which the display cover assembly is disposed.
In addition, in order to prevent the support 30 from being separated from the adhesive layer 50 when the support 30 pulls down the fingerprint identification module 20, it is preferable that, as shown in fig. 8, a plurality of recesses are formed on a surface of the support 30 near the rear cover 203 at positions corresponding to the adhesive layer 50, so that the surface of the support 30 contacting the adhesive layer 50 is uneven, thereby increasing the contact area of the support 30 contacting the adhesive layer 50.
An embodiment of the present invention provides a terminal including any one of the display cover assemblies described above. In addition, the terminal also comprises a display panel, and the display cover plate component is arranged on the display side of the display panel. The above terminal has the same technical effects as the display cover plate assembly provided by the foregoing embodiment, and details are not repeated herein.
It should be noted that, in the embodiment of the present invention, the terminal may be any product or component having a display function, such as a display, a television, a digital photo frame, a mobile phone, or a tablet computer.
Taking the above terminal as a mobile phone, as shown in fig. 3, the cover 10 is divided into a display area C1 and a non-display area C2 located around the display area C1. In order to avoid an influence on the display effect, the mounting hole 101 is generally provided in the non-display region C2. In addition, other through holes, such as a voice control 102, are provided in the non-display area C2. Preferably, the mounting hole 101 may be provided in the lower non-display region C2, and the voice controller 102 may be provided in the upper non-real region C2.
An embodiment of the present invention provides a method for assembling any one of the display cover plates described above, as shown in fig. 9, where the method includes:
s101, a mounting hole 101 is formed in the cover plate 10.
Specifically, as shown in fig. 7, a first through hole 1011 and a second through hole 1012 are formed in the cover plate 10.
S102, the fingerprint identification module 20 penetrates through the mounting hole and is bonded with the support 30, the surface of which is coated with the glue layer 50 and the elastic supporting pad 40.
Specifically, as shown in fig. 10, the fingerprint recognition module 20 is configured by first attaching the touch panel 2010 to the bezel 2011, and then bonding the fingerprint recognizer 202 attached to the rear cover 203 to the touch panel 2010. The seal 60 is then installed on the fingerprint identifier 202.
The surface of the rear cover 203 at the dispensing position is processed by a laser etching process, so that the surface is uneven.
Next, the fingerprint recognition module 20 is disposed in the mounting hole 101. Specifically, as shown in fig. 11, the side surface of the decoration ring 2011 contacts with the side wall of the first through hole 1011, and the whole fingerprint identification module 20 is supported by the side wall of the first through hole 1011. Furthermore, the side of the fingerprint identifier 202 is sealed with the side wall of the second through-hole 1012 by the sealing ring 60.
Next, as shown in fig. 12, elastic support pads 40 and spacers 51 are installed at both ends of the bracket 30. Then, the surface of the support 30 at the dispensing position is processed by a laser etching process to make the surface uneven.
Next, as shown in fig. 13, liquid glue is formed on the uneven surface of the support 30 by a glue dispensing process. Then, the holder 30 shown in fig. 13 is bonded to the fingerprint recognition module 20 by the liquid glue.
S103, pressing the fingerprint identification module 20 and the cover plate 10 together with the support 30 by adopting a pressing process.
Specifically, as shown in fig. 14, a downward force is applied to the fingerprint recognition module 20 and the side surface of the cover plate 10 facing away from the bracket 30, and an upward force is applied to the side surface of the bracket 30 facing away from the cover plate 10. In this way, the adhesive layer 50 between the fingerprint recognition module 20 and the support 30 and the elastic support pad 40 between the cover plate 10 and the support 30 are compressed.
Next, the adhesive layer 50 is dried and cured. After the glue layer 50 is cured, the above-mentioned pressing process is finished. Namely, the force applied to the fingerprint recognition module 20 and the surface of the side of the cover plate 10 facing away from the holder 30, and the force applied to the surface of the side of the holder 30 facing away from the cover plate 10 are removed.
In this case, the middle portion of the bracket 30 is fixedly connected to the fingerprint recognition module 20, and the elastic support pads 40 at the two ends of the bracket 30 are released to rebound when the external force is removed, so as to apply an upward force to the cover plate 10 and apply a downward force to the two ends of the bracket 30, so that the two ends of the bracket 30 are bent in a direction away from the cover plate 10.
In addition, since the cover plate 10 is hard in texture, the cover plate 10 applies a downward reaction force to the elastic support pad 40, and the reaction force is transmitted to the stand 30 through the elastic support pad 40.
In this case, the whole of the support 30 is subjected to a downward force exerted by the elastic support pad 40, and the fingerprint identification module 20 fixedly connected therewith is pulled down by the downward force, so that the touch surface a1 (shown in fig. 1) of the front cover 201 is lower than or flush with the touch surface a2 of the cover plate 10. Therefore, the user can not be scratched by the edge of the front cover 201 of the fingerprint identification module 20 in the process of touching the fingerprint identification module 20.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions within the technical scope of the present invention are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
