Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a fingerprint identification method, and the execution main body of the method is a folding terminal (which can be simply called as a terminal in the follow-up process). The terminal may be a terminal with a fingerprint recognition function, the screen of the foldable terminal is divided into a first screen area and a second screen area at a folding line, the screen of the foldable terminal and the glass cover thereof may be rotated and folded at a certain position, the rotation axis is parallel to the width direction, the rotation axis of the foldable terminal in the solution may be at the center line of the screen and may be folded 180 degrees towards the back (i.e. the folded screen is on the outside, i.e. the foldable terminal is an outside foldable terminal), as shown in fig. 1.
The terminal may include components such as a processor, memory, screen, etc. The processor may be a CPU (central processing Unit) or the like, and may be configured to perform processing related to the screen unlock processing. The Memory may be a RAM (Random Access Memory), a Flash Memory, and the like, and may be configured to store received data, data required by a processing procedure, data generated in the processing procedure, and the like, such as reference fingerprint information of a first finger, reference fingerprint information of a second finger, reference fingerprint information of a third finger, and the like. The screen can be a touch screen, can be used to obtain the fingerprint information of current input, can also be used to detect touch signal etc., and the screen can be the screen that supports fingerprint identification technique, and the user can input own fingerprint information through the optional position of screen, also the terminal can be through screen identification fingerprint promptly.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
step 201, in a state of folding and turning off the screen, when a pressing event of the first screen area and the second screen area is detected, starting a fingerprint identification function.
In implementation, when the user uses the terminal, the terminal may be folded at the center line by operation, as shown in fig. 3, wherein when an included angle between the first screen area and the second screen area (where the screen of the terminal is divided into two areas at the center line, which may be referred to as the first screen area and the second screen area, respectively) is smaller than a preset angle threshold, the terminal may be considered to be currently in the folded state, and when the foldable terminal is in the folded state, the first screen area and the second screen area are located at the outer side. Under the terminal is in the state of folding and turning off the screen, when the user wants to use the terminal again, can pinch up the terminal through the finger, this moment, the terminal will detect the pressing event in first screen region and second screen region, and then, can open the fingerprint identification function, can begin to detect the fingerprint information of pressing the finger on first screen region and second screen region respectively through first screen region and second screen region.
Optionally, the terminal may further start a fingerprint recognition function when detecting that the movement occurs, and the processing procedure of step 201 may be as follows: when the first screen area and the second screen area are detected to be pressed and the folding terminal moves in the folding and screen-off states, the fingerprint identification function is started.
In implementation, when the user no longer uses the terminal, the terminal will turn off the screen after a certain time. Under the terminal is in the state of folding and turning off the screen, when the user wants to use the terminal again, can pinch the terminal through the finger, at this moment, the terminal can detect the terminal through setting up sensors such as gyroscope in inside and take place to remove to can detect the pressing event in first screen region and second screen region, and then, can open fingerprint identification function.
Step 202, in a state that the fingerprint identification function is on, detecting currently input target fingerprint information through the first screen area and the second screen area.
In implementation, after the terminal starts the fingerprint identification function, in a state where the fingerprint identification function is started, the terminal may detect currently input fingerprint information (which may be referred to as target fingerprint information) through the first screen area and the second screen area, that is, may detect fingerprint information of a finger pressed on the first screen area and the second screen area through the first screen area and the second screen area. In addition, the condition that the terminal starts the fingerprint identification function is triggered by pinching the terminal by a finger of a user, and after the fingerprint identification function is started by the terminal, currently input fingerprint information can be detected through the screen.
Optionally, in some cases, the terminal may turn off the fingerprint recognition function, that is, stop detecting the fingerprint information through the screen, and accordingly, the processing procedure may be as follows: when the fingerprint information is not detected through the screen within the preset duration of starting the fingerprint identification function, the fingerprint identification function is closed.
In implementation, a preset time period may be stored in the terminal in advance, where the preset time period may be a smaller value. After the terminal starts the fingerprint identification function, timing can be started, and when the timing duration reaches the preset duration, the fingerprint identification function can be closed when fingerprint information is not detected through the screen. Therefore, when the fingerprint identification function is started by the terminal due to misoperation of a user, the fingerprint identification function can be closed by the terminal in time, and therefore electric quantity can be saved.
And step 203, if the target fingerprint information comprises fingerprint information matched with the pre-stored reference fingerprint information of the first finger and fingerprint information matched with the reference fingerprint information of the second finger, executing screen unlocking processing.
In an implementation, the terminal may store reference fingerprint information of the first finger and reference fingerprint information of the second finger in advance. After the terminal acquires the target fingerprint information, the target fingerprint information can be compared with the pre-stored reference fingerprint information corresponding to each finger, and if the target fingerprint information comprises fingerprint information matched with the pre-stored reference fingerprint information of the first finger and fingerprint information matched with the pre-stored reference fingerprint information of the second finger, the terminal can execute screen unlocking processing. In addition, after the terminal executes the screen unlocking processing, the fingerprint identification function can be closed, namely, the fingerprint information can be stopped to be detected through the screen, so that the terminal can be conveniently operated by a user through the screen.
Optionally, the terminal may execute the screen unlocking process when the target fingerprint information does not include fingerprint information matched with the reference fingerprint information of the third finger, and accordingly, the processing procedure of step 203 may be as follows: and if the target fingerprint information includes fingerprint information matched with the pre-stored reference fingerprint information of the first finger, fingerprint information matched with the reference fingerprint information of the second finger, and fingerprint information matched with the reference fingerprint information of the third finger is not included, executing screen unlocking processing.
In an implementation, the terminal may further store reference fingerprint information of a third finger in advance. In a case where it is determined that the target fingerprint information includes fingerprint information that matches the reference fingerprint information of the first finger stored in advance and fingerprint information that matches the reference fingerprint information of the second finger, the terminal may further determine whether or not fingerprint information that matches the reference fingerprint information of the third finger is included in the target fingerprint information, and if not, the terminal performs screen unlocking processing.
That is, in a state where the fingerprint identification function is turned on, when the user wants the terminal to perform the screen unlocking process, the user may input the fingerprint information of the first finger and the second finger, and may not input the fingerprint information of the third finger, that is, the user may press the screen with the first finger and the second finger, and may ensure that the third finger does not contact the screen. The condition that the user opens the fingerprint identification function through pointing to hold between the fingers the terminal trigger terminal, the user can hold between the fingers the terminal through first finger and second finger (can press the screen through first finger and second finger and hold between the fingers the terminal), and guarantee that the third finger does not contact the screen, and thus, can trigger the terminal and open the fingerprint identification function, after triggering the terminal simultaneously and opening the fingerprint identification function, can acquire the fingerprint information of first finger and second finger through the screen, and then, can realize the purpose of unblock screen, thereby, can improve the efficiency of screen unblock.
In addition, the terminal may light up the screen while performing the screen unlock process.
Alternatively, the first, second and third fingers may be the thumb, middle finger and index finger, respectively, of the same hand.
Optionally, in view of the fact that the target fingerprint information includes fingerprint information matched with the reference fingerprint information of the third finger, the terminal may further perform the following processing: and if the target fingerprint information comprises fingerprint information matched with the pre-stored reference fingerprint information of the third finger, refusing to execute the screen unlocking processing.
In implementation, after the terminal compares the target fingerprint information with the pre-stored reference fingerprint information corresponding to each finger, if it is detected that the target fingerprint information includes fingerprint information matching the reference fingerprint information of the third finger, the terminal may refuse to perform the screen unlocking process.
In this way, it is possible to prevent a phenomenon in which the user unintentionally picks up the terminal (i.e., the user does not pick up the terminal for terminal unlocking), which may be an intentional behavior, from causing the terminal to be unlocked. When the user unconsciously holds the terminal, the user usually uses the thumb and the index finger (or may use the middle finger and the ring finger). In the scheme, the operation method of the pinching and holding actions with the participation of the thumb and the middle finger and without the participation of the index finger is adopted, the unconventional actions are distinguished from the unconscious actions, and the misoperation of the user can be effectively prevented.
Optionally, the reference fingerprint information of each finger pre-stored in the terminal may be pre-recorded by the user, and accordingly, the processing procedure may be as follows: when a fingerprint setting instruction corresponding to a first finger is received, detecting currently input first fingerprint information through a screen, and storing the first fingerprint information as reference fingerprint information corresponding to the first finger; when a fingerprint setting instruction corresponding to a second finger is received, detecting currently input second fingerprint information through a screen, and storing the second fingerprint information as reference fingerprint information corresponding to the second finger; when a fingerprint setting instruction corresponding to a third finger is received, currently input third fingerprint information is detected through a screen, and the third fingerprint information is stored as reference fingerprint information corresponding to the third finger.
In implementation, the user may pre-record reference fingerprint information for each finger. Specifically, a user can trigger the terminal to display a reference fingerprint setting interface through operation, wherein a first finger option, a second finger option and a third finger option can be displayed in the reference fingerprint setting interface. When the user wants to record the reference fingerprint information of the first finger, the user can select a first finger option, at the moment, the terminal can receive a fingerprint setting instruction corresponding to the first finger, and then the currently input first fingerprint information can be detected through the screen, and the first fingerprint information is stored as the reference fingerprint information corresponding to the first finger. When the user wants to record the reference fingerprint information of the second finger, the user can select the second finger option, at this time, the terminal can receive the fingerprint setting instruction corresponding to the second finger, and then the currently input second fingerprint information can be detected through the screen, and the second fingerprint information is stored as the reference fingerprint information corresponding to the second finger. When the user wants to record the reference fingerprint information of the third finger, the user can select a third finger option, and at the moment, the terminal can receive a fingerprint setting instruction corresponding to the third finger, so that the currently input third fingerprint information can be detected through the screen, and the third fingerprint information is stored as the reference fingerprint information corresponding to the third finger.
In addition, when the user uses the terminal, the terminal may be in an unfolded state, and for this case, the terminal may perform the screen unlocking process according to the above steps, or may perform the screen unlocking process according to an existing method, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, when a folding terminal is in a folding and screen-off state and pressing events of a first screen area and a second screen area are detected, a fingerprint identification function is started, wherein when the folding terminal is in the folding state, the first screen area and the second screen area are positioned at the outer side; detecting currently input target fingerprint information through a first screen area and a second screen area in a state that a fingerprint identification function is started; and if the target fingerprint information comprises fingerprint information matched with the pre-stored reference fingerprint information of the first finger and fingerprint information matched with the reference fingerprint information of the second finger, executing screen unlocking processing. Therefore, when a user wants to unlock the terminal, the user can input own fingerprint information through any position of the screen, and the user does not need to input the fingerprint information at a specific position, so that the flexibility can be improved.

When the user manually separates the first casing 41 and the second casing 42, the terminal 100 is changed from the folded state to the unfolded state; when the user manually closes the first housing 41 and the second housing 42, the terminal 100 changes from the unfolded state to the folded state.
In an alternative implementation, the connection assembly 43 of the terminal 100 is of an electric construction, for example, the connection assembly 43 is provided with an electric rotating member such as an electric motor. Under the driving of the electric rotating component, the first housing 41 and the second housing 42 automatically close or separate, so that the terminal 100 has two states of unfolding and folding.
External folding screen terminal
The outer folding screen terminal is a terminal which has a folding angle of 180 degrees and is completely exposed out of the touch display screen in a folding state. As shown in fig. 9, the terminal 100 is an outer folder screen terminal. In the unfolded state, the first supporting surface of the first casing 41 of the terminal 100 is flush with the second supporting surface of the second casing 42 (i.e. the included angle is 180 °), and the first display area 131, the second display area 132 and the third display area 133 of the touch display screen are located on the same plane; in the process of the terminal 100 changing from the unfolded state to the folded state, as shown in fig. 9, the first back surface of the first housing 41 and the second back surface of the second housing 42 are close to each other, and the included angle between the first supporting surface and the second supporting surface is changed from 180 ° to 0 °; in the folded state, as shown in fig. 10, the first supporting surface of the first casing 41 of the terminal 100 is parallel to the second supporting surface of the second casing 42 (the included angle between the first casing 41 and the second casing 42 is 0 °), so that the touch display screen is in a U-shaped folded state, in which the third display area 133 of the touch display screen forms an exposed U-shaped arc surface.
In an alternative implementation, in the folded state, all or part of the display area of the touch display screen is used for displaying the user interface. For example, as shown in fig. 10, in the folded state, only the second display region 132 is used to display the user interface, or only the third display region 133 is used to display the user interface.
In other possible implementations, the foldable angle of the terminal 100 may also be 360 ° (both inward and outward), and in the folded state, the touch display screen is exposed or converged on the terminal, which is not limited in this embodiment.
In the terminal 100 shown in fig. 9 to 10, the first housing 41 and the second housing 42 have the same or similar size, and the folding manner of the terminal 100 is called symmetrical folding. In other possible implementations, the terminal 100 may also be folded asymmetrically. When the asymmetric folding is adopted, the sizes of the first casing 41 and the second casing 42 may be different or different by more than a threshold (for example, 50% or 60% or 70%), and accordingly, the area of the first display region 131 in the touch display screen is different from the area of the second display region 132 by more than a threshold.
Illustratively, as shown in fig. 11, the terminal 100 is an asymmetrically folded outer folded screen terminal, and the first housing 41 has a size larger than that of the second housing 42. In the folded state, the area of the first display region 131 is larger than that of the second display region 132.
In fig. 9 to 11, only by taking an example that the terminal 100 includes two parts of a housing and a connecting assembly for connecting the housing as an example (the terminal is in a two-fold structure), in other possible implementations, the terminal 100 may include n parts of the housing and n-1 connecting assemblies, and accordingly, the touch display screen of the terminal 100 includes 2n-1 display areas, and the n-1 display areas corresponding to the connecting assemblies are made of a flexible material, so as to implement the terminal in the n-fold structure, which is not limited in this embodiment.
At least one other component is also provided in the terminal 100, the at least one other component including: cameras, fingerprint sensors, proximity light sensors, distance sensors, etc. In some embodiments, at least one other component is disposed on the front, side, or back of the terminal 100, such as a fingerprint sensor disposed on the back or side of the housing, a camera disposed above the touch display screen 130.
In other embodiments, at least one other component may be integrated within or below the touch screen display 130. In some embodiments, a bone conduction earpiece is provided inside the terminal 100; other components on the front panel of the conventional terminal are integrated in the whole area or a partial area of the touch display screen 130, for example, after a photosensitive element in the camera is split into a plurality of photosensitive pixels, each photosensitive pixel is integrated in a black area in each display pixel in the touch display screen 130, so that the touch display screen 130 has an image capturing function. The terminal 100 has a higher screen occupation ratio due to the integration of at least one other component within or under the touch display screen 130.
In some optional embodiments, an edge touch sensor is disposed on a single side, or two sides (e.g., two left and right sides), or four sides (e.g., four upper, lower, left and right sides) of the middle frame of the terminal 100, and is configured to detect at least one of a touch operation, a click operation, a press operation, a slide operation, and the like of a user on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like. The user may apply operations on the edge touch sensor to control the application in the terminal 100.
In addition, those skilled in the art will appreciate that the configuration of terminal 100 as illustrated in the above-described figures is not intended to be limiting of terminal 100, and that terminals may include more or less components than those illustrated, or some components may be combined, or a different arrangement of components. For example, the terminal 100 further includes a radio frequency circuit, an input unit, a sensor, an audio circuit, a Wireless Fidelity (WiFi) module, a power supply, a bluetooth module, and other components, which are not described herein again.
In the embodiment of the invention, when a folding terminal is in a folding and screen-off state and pressing events of a first screen area and a second screen area are detected, a fingerprint identification function is started, wherein when the folding terminal is in the folding state, the first screen area and the second screen area are positioned at the outer side; detecting currently input target fingerprint information through a first screen area and a second screen area in a state that a fingerprint identification function is started; and if the target fingerprint information comprises fingerprint information matched with the pre-stored reference fingerprint information of the first finger and fingerprint information matched with the reference fingerprint information of the second finger, executing screen unlocking processing. Therefore, when a user wants to unlock the terminal, the user can input own fingerprint information through any position of the screen, and the user does not need to input the fingerprint information at a specific position, so that the flexibility can be improved.
It will be understood by those skilled in the art that all or part of the steps for implementing the above embodiments may be implemented by hardware, or may be implemented by a program instructing relevant hardware, where the program may be stored in a computer-readable storage medium, and the above-mentioned storage medium may be a read-only memory, a magnetic disk or an optical disk, etc.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
