Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, specific technical solutions of the present application will be described in further detail below with reference to the accompanying drawings in the embodiments of the present application. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
It should be noted that the terms "first \ second \ third" referred to in the embodiments of the present application are only used for distinguishing similar or different objects, and do not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may be interchanged under certain ordering or sequence order, so that the embodiments of the present application described herein can be implemented in other than the order shown or described herein.
The embodiment of the application provides a fingerprint identification method, which is applied to electronic equipment with fingerprint identification capability, for example, the electronic equipment can be equipment with information processing capability, such as a mobile phone, a tablet computer and the like. The functions implemented by the fingerprint identification method can be implemented by calling a program code by a processor in the electronic device, and the program code can be stored in a computer storage medium.
Fig. 1 is a schematic view of an implementation flow of a fingerprint identification method according to an embodiment of the present application, and as shown in fig. 1, the method at least includes the following steps 101 to 103:
Controlling the screen assembly to work, namely actually controlling the screen assembly to refresh a display picture of a screen, wherein a pixel unit for displaying the screen picture is in a light-emitting state (namely a working state); therefore, the light signal reflected by the back plate of the screen assembly can be sensed under the condition that the fingerprint sensor is in the working state.
However, if the fingerprint sensor is in operation and the screen assembly is not in operation, the fingerprint information sensed by the fingerprint sensor is incomplete when the user touches the screen. For example, as shown in fig. 2, if the Time when the user touches the screen includes all or part of a Blank Time (i.e., non-operating Time) of the screen component, while the fingerprint sensor is operating, the fingerprint information sensed by the fingerprint sensor may be incomplete. Such a problem is manifested in the fingerprint image, as shown in fig. 3, a horizontal stripe 301 appears on the fingerprint image 30, thereby affecting the accuracy of fingerprint identification and easily causing misjudgment.
Therefore, in the embodiment of the application, under the condition that the fingerprint sensor is in the working state, the screen assembly is controlled to work, namely, when the fingerprint sensor works, the screen assembly is also working, so that the transverse stripes on the fingerprint image can be avoided, and the accuracy of fingerprint identification is improved.
The screen of the screen assembly may be made of a material having a self-luminous property, or may be made of another material. For example, the screen is an Organic Light-Emitting Diode (OLED) screen or a Liquid Crystal Display (LCD).
And 102, acquiring fingerprint information output by the fingerprint sensor.
And 103, performing fingerprint identification according to the fingerprint information.
When the electronic equipment is realized, the fingerprint information can be compared with a pre-stored fingerprint template, so that fingerprint identification is realized. It should be noted that the fingerprint identification method provided by the embodiment of the present application may be applied to application scenarios such as fingerprint unlocking, fingerprint payment, and fingerprint decryption.
In the embodiment of the application, under the condition that the fingerprint sensor of the electronic equipment is in a working state, the screen assembly of the electronic equipment is controlled to work, so that the problem that the fingerprint information collected by the fingerprint sensor is incomplete and the accuracy of fingerprint identification is poor can be solved.
The embodiment of the present application further provides a fingerprint identification method, which at least includes the following steps 201 to 205:
step 201, receiving a touch operation, where the touch operation is used to unlock the electronic device.
With the continuous development of display technology, electronic devices with a frameless full-screen display panel are favored by consumers. The user can touch any area of the screen of the electronic device to unlock the electronic device.
And 202, responding to the touch operation, and controlling the fingerprint sensor to work.
As can be appreciated, as the application functions of the electronic device increase and the dependence of the user on the electronic device increases, the duration of the electronic device directly affects the user experience. Here, the electronic device controls the fingerprint sensor to operate after detecting the touch operation, not before receiving the touch operation; therefore, the power consumption of the electronic equipment can be saved, and the endurance time of the electronic equipment is prolonged.
In other embodiments, the electronic device controls the fingerprint sensor to operate when detecting that a distance between the living organism and the screen of the screen assembly is less than a distance threshold.
In one example, the biological object may be a finger or a toe of the user, or the like. Compared with the electronic device controlling the fingerprint sensor to start to work after receiving the touch operation, the electronic device controlling the fingerprint sensor to start to work when detecting that the distance between the living body and the screen is smaller than the distance threshold value has the advantages that: the fingerprint information can be acquired more quickly, and the fingerprint identification speed is faster and more sensitive.
Step 203, under the condition that the fingerprint sensor is in the working state, controlling the screen assembly of the electronic device to work, so that the fingerprint sensor senses the optical signal reflected by the back plate of the screen assembly.
When the electronic device is implemented, step 202 and step 203 can be executed in parallel; step 203 may also be performed after step 202 is performed, but it is ensured that the screen assembly is also operational while the fingerprint sensor is operational.
And step 204, acquiring the fingerprint information output by the fingerprint sensor.
And step 205, performing fingerprint identification according to the fingerprint information.
The embodiment of the present application further provides a fingerprint identification method, which at least includes the following steps 301 to 305:
And step 302, responding to the touch operation, and controlling the fingerprint sensor to work intermittently.
It is understood that controlling the fingerprint sensor to operate intermittently means turning on the fingerprint sensor, operating it for a period of time, turning off the fingerprint sensor, resting it for a period of time, continuing to operate again, resting again, etc. For example, the fingerprint sensor is controlled to operate for 15 milliseconds (ms), then the fingerprint sensor is turned off and stopped for 1ms, then the operation is continued for 15ms, and stopped for 1ms, etc. Therefore, the positive leakage generated in the working process of the fingerprint sensor can be released, and the aging speed of components can be slowed down.
In other embodiments, the electronic device controls the fingerprint sensor to operate intermittently upon detecting that a distance between the biological object and the screen of the screen assembly is less than a distance threshold.
Step 303, controlling each non-operating time of the screen assembly to be synchronous with the non-operating time of the fingerprint sensor when the fingerprint sensor is in an operating state, so that the fingerprint sensor senses the optical signal reflected by the back plate of the screen assembly.
For example, as shown in FIG. 4, each inactivity time of the screen assembly is synchronized with the inactivity time of the fingerprint sensor; therefore, even if the time when the user touches the screen just comprises all or part of certain non-working time of the screen component, because the fingerprint sensor does not work at the moment, the occurrence of horizontal stripes in the collected fingerprint image can be avoided, and the fingerprint identification accuracy is improved.
In other embodiments, the electronic device may control the screen assembly to continue operating while the fingerprint sensor is in an operating state. For example, as shown in fig. 5, the electronic device controls the fingerprint sensor to intermittently operate and controls the screen assembly to continuously operate, so that the problem of horizontal stripes of the fingerprint image caused by the time when the user touches the screen, including the non-operating time of the screen assembly, can be avoided, and the accuracy of fingerprint identification can be improved.
In other embodiments, the electronic device may control both the fingerprint sensor and the screen assembly to operate continuously.
And step 304, acquiring the fingerprint information output by the fingerprint sensor.
And 305, performing fingerprint identification according to the fingerprint information.
In the embodiment of the application, the electronic equipment controls the fingerprint sensor to work intermittently, and controls each non-working time of the screen component to be synchronous with the non-working time of the fingerprint sensor, or controls the screen component to work continuously; therefore, the incompleteness of the fingerprint information can be solved, and the accuracy of fingerprint identification is improved.
The embodiment of the present application further provides a fingerprint identification method, which at least includes the following steps 401 to 404:
step 401, when it is detected that the distance between the biological body and the screen of the screen assembly is smaller than a distance threshold, controlling a driving circuit in the electronic device to intermittently output a driving signal to the fingerprint sensor so as to drive the fingerprint sensor to intermittently operate.
For example, the electronic device controls the drive circuit to intermittently output a high level (i.e., an example of a drive signal) for a certain length of time to trigger the fingerprint sensor to operate.
In other embodiments, when the electronic device detects a touch operation, step 401 is executed to control a driving circuit in the electronic device to intermittently output a driving signal to the fingerprint sensor so as to drive the fingerprint sensor to intermittently operate.
Step 402, inputting each driving signal to the screen assembly to drive the screen assembly and the fingerprint sensor to work synchronously, so that the fingerprint sensor senses the optical signal reflected by the back plate of the screen assembly.
In the implementation, the electronic device executes the step 401 and the step 402 in parallel, that is, the electronic device controls the driving circuit to intermittently output the driving signal to the fingerprint sensor and the screen component, and the fingerprint sensor and the screen component share one driving circuit, so that the fingerprint sensor and the screen component can synchronously work, and the circuit cost and the device space can be saved.
Step 403, acquiring the fingerprint information output by the fingerprint sensor.
And step 404, performing fingerprint identification according to the fingerprint information.
In the embodiment of the application, the electronic device controls the driving circuit to intermittently output the driving signal and simultaneously input the driving signal into the fingerprint sensor and the screen assembly so as to drive the two components to work synchronously, thereby solving the problem of poor fingerprint identification accuracy caused by the transverse stripe problem.
The embodiment of the present application further provides a fingerprint identification method, which at least includes the following steps 501 to 505:
step 501, receiving a touch operation, where the touch operation is used to unlock the electronic device.
Step 502, in response to the touch operation, controlling the fingerprint sensor to work for a first duration in each first period, where the first duration is less than the first period.
In other embodiments, the first time period may be equal to the first period, i.e. the electronic device controls the fingerprint sensor to operate continuously.
Step 503, controlling the screen assembly to operate for a second time period in each second period while controlling the fingerprint sensor to start operating, wherein the second time period is less than the second period; wherein a first difference between the first period and the first duration is equal to a second difference between the second period and the second duration; the second period is N times the first period, and N is an integer greater than 0; therefore, each non-working time of the screen assembly and the non-working time of the fingerprint sensor can be synchronous, so that the fingerprint sensor can sense the optical signal reflected by the back plate of the screen assembly, the output fingerprint image information has no transverse stripe, and the accuracy of fingerprint identification is improved.
It will be appreciated that the first difference and the second difference are the off-times of the fingerprint sensor and the screen assembly, respectively, during each cycle. In the embodiment of the present application, the lengths of the first period and the second period are not limited, but the second period is N times the first period. For example, the second period is equal to the first period, i.e., the fingerprint sensor and the screen assembly operate in synchronization; as shown in fig. 6, the second period is 4 times the first period.
In other embodiments, in the case that the screen of the screen assembly has a self-luminous characteristic, before the touch operation is received, the screen assembly is controlled to operate for a third time period in each second period, wherein the third time period is less than the second period, and the third time period is less than the second time period.
For example, when the electronic device displays static wallpaper, before receiving a touch operation, the screen assembly is controlled to operate for a third duration in each second period, that is, the display picture is refreshed at a lower operating frequency, so as to save power consumption and prolong the endurance time of the electronic device; after receiving the touch operation, the screen assembly is controlled to work for a second time length in each second period, namely, the display picture is refreshed at a higher working frequency, so that the acquisition rate of the fingerprint image is improved, and the fingerprint identification speed is further improved. At present, screens with self-luminous properties are OLED screens.
Step 504, acquiring the fingerprint information output by the fingerprint sensor.
And 505, performing fingerprint identification according to the fingerprint information.
In the embodiment of the application, the fingerprint sensor and the screen component are controlled to work periodically at the same time, the second period corresponding to the screen component is N times of the first period corresponding to the fingerprint sensor, and the non-working time of the first period and the non-working time of the second period are equal; therefore, each non-working time of the screen assembly is synchronous with the non-working time of the fingerprint sensor, so that the phenomenon that the collected fingerprint image has transverse stripes is avoided, and the accuracy of fingerprint identification is improved.
With the updating of smart phones, the demand of consumers for identifying fingerprints under a screen is more and more strong, the development of the technology for identifying fingerprints under the screen is promoted, the current technology for identifying fingerprints under the screen is mainly applied to an OLED screen, the OLED screen is a self-luminous screen, and a fingerprint sensor is placed on the back of the screen by utilizing the self-luminous characteristic of materials so as to realize the collection and identification of fingerprint images.
The current scheme of the under-screen fingerprint of the OLED screen is limited by cost and technical limit, and is mainly used for single-point or local area identification, and a consumer needs to accurately identify an identification area; then, the fingerprint identification can be completed by pressing the area, and the use convenience needs to be improved urgently, so that the development of a novel full-screen fingerprint identification technology becomes more important; the full-screen fingerprint identification technology in the screen is a technology which does not influence the structure of the whole machine, and has great application prospect in the future. Currently, the cross-striation phenomenon caused by the difference between the working period of the fingerprint sensor and the scanning period of the OLED screen occurs in the OLED screen in combination with the single-point or area screen, as shown in fig. 2, a Blank time (i.e., Blank time) exists in each frame of the screen and the fingerprint sensor, and the Blank time is used for resetting the frame signal. When there is the difference in the refresh frequency of screen and fingerprint sensor, the Blank time image of screen can be gathered when fingerprint sensor gathers the fingerprint image, because the screen is the black state this moment, can show as the horizontal stripe on the fingerprint image of fingerprint sensor collection, and the appearance of this kind of horizontal stripe can influence fingerprint identification performance.
Based on this, an exemplary application of the embodiment of the present application in a practical application scenario will be described below.
The embodiment of the application provides a full-screen fingerprint identification intra-screen fingerprint driving design, which has the following implementation scheme:
first, as shown in the left diagram (a) of fig. 7, a circuit of a screen (screen may refer to OLED or LCD, hereinafter collectively referred to as screen) is composed of a scanning circuit and a data circuit. As shown in the right diagram (b) in fig. 7, the scanning circuit is designed by using a pass-through circuit, the Gate1 receives a signal of Clock 1(Clock1), opens the Gate circuit in the first row, when the Clock3 signal appears, the Gate1 is pulled down, the Gate circuit in the first row is closed, simultaneously the Clock3 circuit opens the third row circuit, the Gate3 passes through the Gate5 again, the Gate5 passes through the Gate3 and closes, and the sequential circulation is performed, so that all rows in one frame are opened sequentially, the opening and closing of the Gate2 are the same, and the pass-through circuit can use the Clock circuit far lower than the number of rows to realize the row circuit being opened step by step.
Secondly, a fingerprint sensor is integrated in the screen in the fingerprint scheme in the screen, a driving circuit of the fingerprint sensor is placed in the screen, a pass-stage circuit is also used for driving scanning signals of the fingerprint sensor, as shown in fig. 8, a Clock signal is output in an external circuit of the screen, the fingerprint sensor and the screen share the Clock signal, the common frequency of the screen/fingerprint scanning signals is realized, and when the fingerprint sensor does not receive a fingerprint working state instruction, the fingerprint sensor does not work; when the fingerprint sensor receives the fingerprint working state instruction, the fingerprint sensor works. Moreover, the fingerprint sensor and the screen display have consistency of opening and closing, and the scanning frequency is consistent, so that the transverse stripes of the acquired fingerprint image can be avoided, and the fingerprint identification performance is improved; meanwhile, as one clock signal is shared, the fingerprint sensor does not need an additional driving circuit, thereby being beneficial to cost optimization.
In the embodiment of the application, the design of the fingerprint drive circuit for fingerprint identification in the screen is provided, and the screen realizes the consistency of the refreshing frequency of the fingerprint sensor and the screen under the condition that the extra drive load is not added, so that the fingerprint identification performance is improved, and the cost is reduced.
