DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] Generally, in order to realize the fingerprint recognition function at two different positions (two different screens or two different areas on one screen) of a terminal device, two fingerprint sensors need to be installed on the terminal device. On the one hand, the fingerprint sensor can only be used at a fixed position, which affects the flexibility of the application of the fingerprint recognition function. In addition, the cost of installing multiple fingerprint sensors is high. In view of this problem, an embodiment of the present disclosure provides a terminal device, in which the position of the fingerprint sensor in the terminal device is variable. The method is introduced below in conjunction with a specific embodiment.

[0025] Figure 1 A schematic diagram of the structure of a terminal device provided in an embodiment of the present disclosure. The terminal device can at least be understood as a terminal device having at least one screen, such as a candy-bar mobile phone with one screen or a folding screen mobile phone with multiple screens, etc., but is not limited to mobile phones.

[0026] like Figure 1 As shown, the terminal device mainly includes a screen assembly 110 , a fingerprint sensor 120 , a transmission mechanism 130 , and a controller 140 .

[0027] Specifically, the terminal device in the embodiment of the present disclosure includes a foldable terminal device.

[0028] The screen assembly 110 includes a first screen and a second screen. The first screen is arranged on a first surface of the terminal device, and the second screen is arranged on a second surface of the terminal device. The first surface and the second surface can be different surfaces on the terminal device that are opposite to each other, or can be different areas of the same surface on the terminal device. For example, when the terminal device is a foldable terminal device, the first screen can be exemplarily understood as the main screen of the foldable terminal device, and the second screen can be exemplarily understood as the sub-screen of the foldable terminal device. Figure 1 The fingerprint sensor 120 is disposed below the screen assembly 110 (the "below" referred to here refers to the side opposite to the side displayed on the screen), and is used to collect user fingerprint patterns to implement fingerprint recognition.

[0029] The fingerprint sensor 120 referred to in the embodiments of the present disclosure may be any type of sensor, such as an ultrasonic fingerprint sensor, an optical fingerprint sensor, and the like.

[0030] The fingerprint sensor 120 is disposed on the transmission mechanism 130 , and the transmission mechanism 130 is used to drive the fingerprint sensor 120 to move.

[0031] For example, Figure 2 is a schematic diagram of the structure of a fingerprint sensor provided by an embodiment of the present disclosure, such as Figure 2 As shown, in Figure 2 The fingerprint sensor 120 is exemplarily implemented as an optical fingerprint sensor, including a photosensitive layer 210 and a flexible substrate 220 .

[0032] The photosensitive layer 210 is disposed on the surface of the flexible substrate 220. The photosensitive layer 210 receives light reflected from the fingerprint of the user's finger and converts the light into an electrical signal. The photosensitive layer 210 is composed of a plurality of photosensitive units, each of which can receive light reflected from the fingerprint of the user's finger and convert the light into an electrical signal.

[0033] The electrical signal will be transmitted to the central processing unit (CPU) of the terminal device, and the CPU will realize the fingerprint recognition function. Optionally, the electrical signal can also be transmitted to the fingerprint chip ( Figure 2 In the embodiment shown in FIG. 1 , the fingerprint recognition function is realized by a fingerprint chip. The fingerprint chip refers to a chip with built-in fingerprint recognition technology.

[0034] The flexible substrate 220 is disposed on the transmission mechanism 130 and is used to support the photosensitive layer 210. The flexible substrate 220 is made of a material that can be deformed under the action of an external force and can return to its original shape after the external force is removed, and does not change its own performance after deformation, thereby ensuring that the fingerprint sensor will not be damaged when it is moved under force.

[0035] In the embodiment of the present disclosure, the controller 140 is electrically connected to the transmission mechanism 130 and is used to control the transmission mechanism 130 to move the fingerprint sensor.

[0036] For example, the controller 140 can determine the target position of the fingerprint sensor 120 according to whether the screen of the terminal device is lit. For example, when the first screen is lit, the controller 140 sends a first drive signal to trigger the transmission mechanism 130 to move the fingerprint sensor 120 to a position facing the first screen, and when the second screen is lit, the controller 140 sends a second drive signal to trigger the transmission mechanism 130 to move the fingerprint sensor 120 to a position facing the second screen.

[0037] Optionally, when the transmission mechanism 130 moves the fingerprint sensor 120, the fingerprint sensor 120 may be moved in a clockwise direction or a counterclockwise direction. For example, when the target position of the fingerprint sensor 120 is at a position facing the first screen, the transmission mechanism 130 may be moved in a clockwise direction, and when the target position of the fingerprint sensor 120 is at a position facing the second screen, the transmission mechanism 130 may be moved in a counterclockwise direction. Of course, this is only an example and not a sole limitation.

[0038] A terminal device provided by an embodiment of the present disclosure includes: a screen assembly 110, the screen assembly 110 includes a first screen and a second screen, a fingerprint sensor 120, the fingerprint sensor 120 is arranged below the screen assembly 110, a transmission mechanism 130, the transmission mechanism 130 is used to transmit the fingerprint sensor 120, and a controller 140, the controller 140 is electrically connected to the transmission mechanism 130, and the controller 140 is used to control the transmission mechanism 130 to move the fingerprint sensor 120 to the bottom of the second screen, or to move the fingerprint sensor 120 to the bottom of the first screen. The embodiment of the present disclosure can move the fingerprint sensor to a position facing the first screen or the second screen through the transmission mechanism, so that only one fingerprint sensor is set on the terminal device, and the fingerprint recognition function can be realized at different positions of the terminal device, thereby reducing the cost of the terminal device and improving the product competitiveness of the terminal device.

[0039] For example, Figure 3 is a schematic diagram of a transmission mechanism provided by an embodiment of the present disclosure, such as Figure 3As shown, in one embodiment, the conveying mechanism 130 referred to in the embodiment of the present disclosure may include a conveying shaft 310 and a conveyor belt 320. The conveying shaft 310 is used to drive the conveyor belt 320 to move, and the number of the conveying shafts 310 can be set according to demand. The controller 140 is electrically connected to the conveying shaft 130, and the controller 140 is used to control the conveying shaft 310 to drive the conveyor belt 320 to move.

[0040] Furthermore, the conveying shaft 310 may also be a set of gears capable of driving the conveying belt 320 to move.

[0041] The fingerprint sensor 120 referred to in the present disclosure may be disposed on the conveyor belt 320. Figure 2 In the structure shown, the flexible substrate of the fingerprint sensor 120 can be fixed on the conveyor belt 320, or the conveyor belt 320 itself can be directly processed into the flexible substrate.

[0042] The embodiment of the present disclosure provides a transmission structure, which includes: a transmission shaft 310 and a conveyor belt 320. The transmission shaft 310 is used to drive the conveyor belt 320 to move, and the number 310 of the transmission shafts 310 can be set according to demand. The embodiment of the present disclosure can drive the conveyor belt to move the fingerprint sensor through the transmission shaft, so that only one fingerprint sensor is set on the terminal device, and the fingerprint recognition function can be realized at different positions of the terminal device, thereby reducing the cost of the terminal device and improving the product competitiveness of the terminal device.

[0043] For example, Figure 4 A top view schematic diagram of a transmission mechanism provided in another embodiment of the present disclosure is shown as follows: Figure 4 As shown, in another implementation of the embodiment of the present disclosure, the conveying mechanism 130 referred to in the embodiment of the present disclosure may include a folding plate 410 and a flip module 420 .

[0044] Specifically, in some implementations, the fingerprint sensor ( Figure 4 The folding plate 410 is disposed on a flip module 420, and the flip module 420 is used to rotate the folding plate 410 to a position facing the first screen, or to rotate the folding plate 410 to a position facing the second screen.

[0045] The flip module 420 includes a rotating shaft 421 and a driving unit 422, wherein the driving unit 422 is connected to a controller, and the controller is used to control the driving unit 422 to drive the rotating shaft 421 to rotate. Optionally, when the controller controls the driving unit 422 to drive the rotating shaft 421 to rotate, the rotating shaft 421 can be rotated in a clockwise direction or a counterclockwise direction. For example, when the target position of the folding plate 410 is a position facing the first screen, the rotating shaft 421 rotates in a clockwise direction, and when the target position of the folding plate 410 is a position facing the second screen, the rotating shaft 421 rotates in a counterclockwise direction.

[0046] The folding plate 410 is in an unfolded state at a position facing the first screen or at a position facing the second screen. During the rotation process, the folding plate is in a folded state. The folding state of the folding plate can be controlled by a controller.
