mobile terminals

Technical Field

The present invention relates to the technical field of communication equipment, and in particular to a mobile terminal.

Background Art

At present, fingerprint recognition technology is widely used. Fingerprint recognition technology can be seen not only in access control and attendance systems, but also in more fingerprint recognition applications on the market: such as laptops, mobile phones, cars, bank payments, etc.

Taking mobile phones as an example, the stacking design of the fingerprint recognition module and the display screen is conducive to increasing the screen-to-body ratio of the mobile phone display area. At the same time, the flexible display screen can increase the image display area of the mobile terminal, thereby realizing a large-screen display. However, in the process of stacking the fingerprint recognition module and the flexible display screen, the flexible display screen is usually fixed to the bearing surface of the shell and the top surface of the fingerprint recognition module. However, it is difficult for the top surface of the fingerprint recognition module to be precisely flush with the bearing surface of the shell, and it is also difficult to seamlessly combine with the bearing surface of the support member. This results in poor installation flatness of the flexible display screen, affecting the display effect.

Summary of the Invention

The technical problem to be solved by the present invention is to provide a mobile terminal to improve the installation flatness of a flexible display screen.

In order to achieve the above-mentioned purpose, an embodiment of the present invention provides a mobile terminal, including a flexible display screen, a fingerprint recognition module and a shell, the shell having a top surface and a side surface connected to each other, the side surface being provided with a mounting groove, the mounting groove being used to accommodate the fingerprint recognition module, the flexible screen including a fixed part and a movable part connected to each other, the fixed part being attached to the top surface, the movable part extending out of the top surface, when the movable part is bent relative to the fixed part, the movable part covers the side surface, the fingerprint recognition module performs fingerprint recognition through the flexible display screen, and when the movable part is flattened relative to the fixed part, the fingerprint recognition module is exposed outside the flexible display screen to facilitate fingerprint recognition by attaching the finger to the side surface.

Compared with the prior art, the present invention has the following beneficial effects:

Since the fingerprint recognition module is arranged outside the top surface of the shell, during the assembly process of the mobile terminal, the flexible display screen is directly attached to the top surface of the shell, so the fingerprint recognition module will not hinder the fixation between the flexible display screen and the shell, thereby improving the installation flatness of the flexible display screen; in addition, when the flexible display screen is in a folded state, the fingerprint recognition module and the flexible display screen are stacked, thereby improving the screen-to-body ratio of the mobile terminal; when the flexible display screen is in a folded state, the user performs fingerprint recognition through the flexible display screen, and when the flexible display screen is in an unfolded state, the user places the finger directly on the shell for fingerprint recognition. The embodiment of the present invention enables the flexible display screen to present different fingerprint recognition methods in the unfolded and folded states, thereby increasing interest and improving user experience.

DETAILED DESCRIPTION

The embodiments of the present application are described below with reference to the accompanying drawings.

1 to 3 , an embodiment of the present invention provides a mobile terminal 100. The mobile terminal 100 may be a portable electronic device or communication device having a flexible display screen 10, such as, but not limited to, a smartphone, a personal digital assistant (PDA), a tablet computer, a notebook, a wearable device, or the like.

The mobile terminal 100 includes a flexible display screen 10, a fingerprint recognition module 30 and a housing 20. The housing 20 has a top surface 201 and a side surface 202 connected to each other. The top surface 201 is arranged toward the user and is used to support the flexible display screen 10. The side surface 202 is provided with a mounting groove 203, and the opening 208 of the mounting groove 203 faces the outside of the housing 20. The mounting groove 203 is used to accommodate the fingerprint recognition module 30. The flexible screen display screen 10 includes a fixed portion 101 and a movable portion 102 connected to each other. The fixed portion 101 is attached to the top surface 201, and the movable portion 102 extends out of the top surface 201. When the movable portion 102 is bent relative to the fixed portion 101, the movable portion 102 covers the side surface 202, and the fingerprint recognition module 30 performs fingerprint recognition through the flexible display screen 10. When the movable portion 102 is flattened relative to the fixed portion 101, the fingerprint recognition module 30 is exposed outside the flexible display screen 10, allowing a finger to be placed against the side surface 202 for fingerprint recognition. In this embodiment, the movable portion 102 covering the side surface 202 means that the movable portion 102 is in contact with the side surface 202. However, the bonding between the movable portion 102 and the side surface 202 is different from the bonding between the fixed portion 101 and the top surface 201. The former is a movable bonding, with the surfaces in contact, while the latter is a fixed bonding, with the surfaces fixed.

In this embodiment, when assembling the mobile terminal 100, the fingerprint recognition module 30 can be first installed in the installation groove 203 on the side surface 202 of the housing 20. Then, the fixed portion 101 of the flexible display 10 is attached to the top surface 201 of the housing 20, so that the top surface 201 of the housing 20 becomes the supporting surface of the flexible display 10. The movable portion 102 of the flexible display 10 can be bent freely, allowing the flexible display 10 to be unfolded to present a large display screen, or folded for easy storage and carrying. When the movable portion 102 is bent relative to the fixed portion 101, the movable portion 102 covers the side surface 202, so that the fingerprint recognition module 30 is disposed between the flexible display 10 and the housing 20. At this point, when the user places their finger on the flexible display 10 in the area corresponding to the fingerprint recognition module 30, the fingerprint recognition module 30 transmits a light signal through the flexible display 10. This light signal is reflected by the fingerprint of the finger, passes through the flexible display 10, and is received by the fingerprint recognition module 30, thereby realizing the user's fingerprint collection and recognition. When the movable portion 102 is flattened relative to the fixed portion 101, the flexible display 10 is spread out on the plane of the top surface 201, so that the fingerprint recognition module 30 is exposed outside the flexible display 10. The user can directly place their finger on the fingerprint recognition module 30 to realize fingerprint recognition.

Since the fingerprint recognition module 30 is arranged outside the top surface 201 of the shell 20, during the assembly process of the mobile terminal 100, the flexible display screen 10 is directly attached to the top surface 201 of the shell 20, so the fingerprint recognition module 30 will not hinder the fixation between the flexible display screen 10 and the shell 20, thereby improving the installation flatness of the flexible display screen 10; in addition, when the flexible display screen 10 is in the folded state, the fingerprint recognition module 30 and the flexible display screen 10 are stacked, thereby improving the screen-to-body ratio of the mobile terminal 100; when the flexible display screen 10 is in the folded state, the user performs fingerprint recognition through the flexible display screen 10, and when the flexible display screen 10 is in the unfolded state, the user places the finger directly on the shell 20 for fingerprint recognition, thereby realizing that the flexible display screen 10 presents different fingerprint recognition methods in the unfolded and folded states, increasing fun and improving user experience.

In this embodiment, the fingerprint recognition module 30 is an optical fingerprint recognition module 30 that recognizes fingerprint images through optical signals. The optical signal recognized by the fingerprint recognition module 30 can be emitted by the module itself, passing through the flexible display 10 and then reflected by the user's finger, or emitted by the flexible display 10 and then reflected by the user's finger, with the reflected light passing through the flexible display 10 and then entering the fingerprint recognition module 30. Of course, in other embodiments, the fingerprint recognition module 30 can also be a capacitive fingerprint recognition module 30 or an ultrasonic fingerprint recognition module 30, etc.

Optionally, the flexible display screen 10 is a bendable display panel. The flexible display screen 10 can be a touch screen to simultaneously realize display and touch functions. The flexible display screen 10 can be an OLED (Organic Light-Emitting Diode) display panel.

In this embodiment, referring to FIG. 2 , the side surface 202 includes a bottom surface 204 and a peripheral surface 205. The bottom surface 204 is disposed opposite the top surface 201, and the peripheral surface 205 is connected between the top surface 201 and the bottom surface 204. Optionally, the mounting groove 203 may be provided on the side surface 202 or on the bottom surface 204. The number of mounting grooves 203 may be multiple. The multiple mounting grooves 203 may be provided on the side surface 202 or/and on the bottom surface 204. Multiple fingerprint recognition modules 30 are provided in the multiple mounting grooves 203.

Referring to FIG. 3 , in a specific embodiment, the mounting groove 203 is provided on the peripheral surface 205 of the housing 20. When the flexible display 10 is in the unfolded state, the flexible display 10 extends within the plane of the top surface 201. Since the peripheral surface 205 intersects with the top surface 201, the flexible display 10 is not covered by the peripheral surface 205, and thus the fingerprint recognition module 30 is exposed outside the flexible display 10.

When the flexible display screen 10 is in a folded state, the movable portion 102 bends toward the circumferential surface 205 relative to the fixed portion 101 and covers the circumferential surface 205. At this time, the fixed portion 101 can be attached to the circumferential surface 205, so that the fingerprint recognition module 30 is arranged between the shell 20 and the flexible display screen 10, and the fingerprint recognition module 30 collects fingerprints through the flexible display screen 10.

It can be understood that the flexible display screen 10 in this embodiment has a light-transmitting area 103. When the movable part 102 covers the side surface 202, the light-transmitting area 103 is opposite to the mounting groove 203, so that the fingerprint recognition module 30 can send and collect light signals through the light-transmitting area 103.

As an optional embodiment, referring to FIG4 , the mounting slot 203 has an opening 208 facing the exterior of the housing 20, and further includes a bottom wall 206 and side walls 207. The bottom wall 206 is opposite the opening 208, and the side walls 207 are connected to the bottom wall 206 and the opening 208. The fingerprint recognition module 30 is mounted on the bottom wall 206. The fingerprint recognition module 30 can be bonded to the bottom wall 206. It is understood that this application does not limit the shape and size of the mounting slot 203.

Optionally, the side wall 207 is provided with a supporting portion 209 , which supports the peripheral side of the fingerprint recognition module 30 to improve the installation stability of the fingerprint recognition module 30 in the installation groove 203 , thereby increasing the recognition efficiency of the fingerprint recognition module 30 .

In a specific embodiment, when the flexible display screen 10 covers the side surface 202, the flexible display screen 10 is roughly parallel to the side surface 202. A certain relative positional relationship is formed between the signal collection surface of the fingerprint recognition module 30 and the surface of the fingerprint recognition module 30 that is attached to the bottom wall 206, such as being parallel or forming a predetermined angle. Preferably, the signal collection surface of the fingerprint recognition module 30 is parallel to the surface of the fingerprint recognition module 30 that is attached to the bottom wall 206 of the groove. Then, setting the bottom wall 206 parallel to the side surface 202 can make the signal collection surface of the fingerprint recognition module 30 parallel to the flexible display screen 10, so that the fingerprint recognition module 30 can better collect the light signal passing through the flexible display screen 10, and therefore, the fingerprint recognition module 30 has a higher recognition accuracy.

Optionally, the depth of the mounting groove 203 can be greater than the thickness of the fingerprint recognition module 30. In this case, the fingerprint recognition module 30 can not only be completely accommodated in the mounting groove 203, but also a gap is formed between the fingerprint recognition module 30 and the side surface 202, which reduces the difficulty of assembly and reserves space for other assembly parts.

As an optional embodiment, based on the above embodiment, please refer to Figure 4, the shell 20 also includes a limit block 210, the limit block 210 is protruded on the side wall 207 of the installation groove 203, the limit block 210 has a first limit surface 211, the first limit surface 211 faces the bottom wall 206, and the surface of the fingerprint recognition module 30 away from the bottom wall 206 is pressed against the first limit surface 211.

In this embodiment, the first limiting surface 211 is used to limit the position of the fingerprint recognition module 30 in the direction toward the opening 208 of the installation slot 203. By setting the first limiting surface 211, the installation stability of the fingerprint recognition module 30 in the axial direction of the installation slot 203 is improved, thereby increasing the recognition efficiency of the fingerprint recognition module 30.

In this embodiment, the stopper 210 has a certain degree of deformation capability under the action of an external force. When the external force causes the stopper 210 to deform, the stopper 210 returns to its original shape after the fingerprint recognition module 30 is installed in the installation slot 203 and the external force is removed. The provision of the stopper 210 helps reduce the difficulty of assembling the fingerprint recognition module 30.

Optionally, a pressing member 212 is provided on the bottom wall 206 of the mounting groove 203. The pressing member 212 is deformed under the action of an external force. The pressing member 212 is used to press the fingerprint recognition module 30 against the first limiting surface 211. At this time, the bottom wall 206, the pressing member 212, and the first limiting surface 211 cooperate with each other to better limit the position of the fingerprint recognition module 30. At the same time, the pressing member 212 can absorb a portion of the process tolerance, thereby reducing the difficulty of assembling the fingerprint recognition module 30.

Specifically, the pressing member 212 is an elastic member, such as a spring, foam, rubber, etc. Of course, in other embodiments, the pressing member 212 can also be a flexible member, as long as the pressing member 212 can cooperate to press the fingerprint recognition module 30 .

As an optional embodiment, based on the above embodiment, please refer to Figure 5, the mobile terminal 100 also includes a light-transmitting cover plate 40, which covers the opening 208 of the mounting slot 203. The light-transmitting cover plate 40 is disposed at the opening 208 of the mounting slot 203, and can be specifically disposed inside or outside the opening 208 of the mounting slot 203. The light-transmitting cover plate 40, while transmitting the optical signal for fingerprint recognition, also serves to block dust and water stains, and protect the fingerprint recognition module 30 in the mounting slot 203 from damage. This embodiment can be implemented alone or in combination with the above embodiments.

Furthermore, the color of the light-transmitting cover 40 is the same as or similar to the color of the side surface 202 , that is, it is difficult for a user to distinguish the color difference between the light-transmitting cover 40 and the side surface 202 with the naked eye, and no visual color difference will be produced, thereby hiding the mounting groove 203 and improving the overall visual effect of the mobile terminal 100 .

Furthermore, referring to Figure 6 , the limiting block 210 forms a second limiting surface 213 on the sidewall 207 of the mounting slot 203. The second limiting surface 213 faces the opening 208 of the mounting slot 203. The light-transmitting cover plate 40 has a first surface 401, which faces the bottom wall 206 and abuts against the second limiting surface 213. The second limiting surface 213 is used to limit the position of the light-transmitting cover plate 40 toward the bottom wall 206. The provision of the second limiting surface 213 improves the axial installation stability of the light-transmitting cover plate 40 in the mounting slot 203.

Optionally, the light-transmitting cover plate 40 may be attached to the outside of the opening 208 of the mounting slot 203, or may be located within the mounting slot 203. When the light-transmitting cover plate 40 is installed in the mounting slot 203, the size of the light-transmitting cover plate 40 may be substantially the same as the size of the opening 208 of the mounting slot 203, so that the light-transmitting cover plate 40 fits neatly within the mounting slot 203. In this case, the periphery of the light-transmitting cover plate 40 may be bonded to the sidewall 207 of the mounting slot 203 to secure the light-transmitting cover plate 40 within the mounting slot 203.

Furthermore, the light-transmitting cover plate 40 also has a second surface 402 disposed opposite the first surface 401, and the second surface 402 is flush with the side surface 202. The first surface 401 is parallel to the second surface 402. If the signal collection surface of the fingerprint recognition module 30 is parallel to the side surface 202, then the signal collection surface of the fingerprint recognition module 30 is also parallel to the first surface 401 and the second surface 402. In this way, the optical signals emitted and collected by the fingerprint recognition module 30 can directly pass through the light-transmitting cover plate 40 and will not be refracted by the first surface 401 and the second surface 402, thereby reducing optical signal loss and improving the accuracy and efficiency of fingerprint recognition.

When the fingerprint recognition module 30 is exposed outside the flexible display screen 10, the finger can be placed directly on the second surface 402 for fingerprint recognition. The second surface 402 is flush with the side surface 202, which can increase the comfort of placing the finger on the second surface 402.

When the movable portion 102 is bent relative to the fixed portion 101, the flexible display 10 adheres to the second surface 402 and the side surface 202. This allows the flexible display 10 to be parallel to the second surface 402, reducing optical signal loss. The flushing of the second surface 402 with the side surface 202 increases the smoothness of the flexible display 10 and improves fingerprint recognition accuracy.

In a mobile terminal 100 provided in an embodiment of the present application, the housing 20 further includes components such as a mainboard and a power supply (not shown). The fingerprint recognition module 30 is electrically connected to the mainboard, and the mainboard is electrically connected to the power supply. The mainboard, the power supply and the fingerprint recognition module 30 cooperate to realize the fingerprint recognition function of the mobile terminal 100. The specific structure, positional relationship, connection relationship and control relationship of these components can be implemented in a variety of ways, which are not limited here.

The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
