In an embodiment, the display module supporting fingerprint recognition may include a display 108 and a fingerprint october 109. Wherein, the fingerprint sensor 109 provides an input interface of the electronic device 100 to the user, and the display 108 provides an output interface of the electronic device 100 to the user.

The fingerprint sensor 109 and the fingerprint touch controller 1072 in one embodiment may implement a fingerprint recognition function for the entire area of the display 108, wherein the fingerprint touch detection technique may be implemented by optical, acoustic, capacitive or other principles.

The fingerprint touch detection will be described below by taking a capacitive fingerprint sensor as an example with reference to FIGS. 2 to 4.

Capacitance refers to the ability to accommodate an electric field. The capacitance of the parallel plate capacitor is C = εS / d; where ε is the dielectric constant of the dielectric between the plates, S is the plate area, and d is the distance between the plates. It can be seen from the above formula that as the distance between the plates decreases, the capacitance value increases; conversely, as the distance between the plates increases, the capacitance value decreases.

As shown in FIG. 2(a), the basic unit of the capacitive fingerprint sensor may include a transmitter (Transmitter) and a receiver (Rx), which constitute a capacitor. In the working state, the fingerprint touch controller first charges the capacitor composed of the emitter and the receiver. The line in Fig. 2(a) indicates the electric field between the two poles in the absence of the operating medium, and the density of the lines indicates the distribution of the strength of the electric field.

Figure 2(b) and Figure 2(c) show that when the finger approaches the fingerprint sensor, the electric field between the two stages changes significantly because the finger forms a capacitor between the emitter and the receiver. Thereby forming an electric field. Since the emitter plate has a large area, the electric field between the finger and the emitter is larger than the electric field between the finger and the receiver. The proximity of the finger weakens the electric field between the emitter and the receiver, reduces the voltage value sampled by the receiver, and the change in the capacitance value can be calculated by the change in the voltage value.

The fingerprint has a gully, the peak is in contact with the surface of the display module of the electronic device, the distance between the capacitor formed by the emitter and the emitter is small, and the variation of the capacitance is large, and the valley has a distance from the surface of the display module and is formed between the emitter and the emitter. The capacitor distance is large and the capacitance change is small. The fingerprint image is drawn using the detected change in capacitance value, as shown in Figure 3.

In an embodiment, as shown in FIG. 4, the fingerprint sensor can support two detection modes. In FIG. 4, the solid line indicates the receiver array, and the chain line indicates the emitter array. In Figure 4, the receiver array is laterally disposed and the emitter array is vertically disposed. However, this application is not limited thereto. In other embodiments, the array of receivers can be vertically disposed and the array of emitters can be disposed laterally.

FIG. 4(a) can support detecting a fingerprint image in which all channels of the emitter (TX) and the receiver (RX) of the display area array are all turned on, and each node (ie, the intersection of the emitter array and the receiver array) is detected. The value of the capacitance changes, thereby drawing a fingerprint image, and the coordinate value of the finger touch position can be calculated from the fingerprint image. In FIG. 4(b), part of the channels of the emitter array and the receiver array are closed, the interlaced spacers are scanned, the capacitance value of each node of the opened channel is detected, and the coordinate value of the finger touch position is calculated, and The corresponding gesture is identified by information such as coordinate position, touch area, and time. This mode saves power consumption from the previous mode in terms of detection and calculation.

Figure 4 shows the switching of the two detection modes by controlling the number of channel openings. However, this application is not limited thereto. In other embodiments, the detection mode can also be switched by adjusting the driving voltage to achieve a different signal to noise ratio.

It should be noted that, in an embodiment, since the fingerprint sensor can implement the fingerprint recognition function of the entire area of the display, the coordinate system used when determining the coordinates of the fingerprint touch position can be consistent with the coordinate system used by the display interface on the display. Or there is a correspondence between the two. However, this application is not limited thereto.

In other embodiments, if the fingerprint detection in the display screen is implemented by optical (such as infrared) or acoustic (such as ultrasonic) principles, the fingerprint image can also be drawn by detecting the difference between the fingerprint sensor and the distance between the fingerprint valley and the peak. Calculate the touch location.

FIG. 5 is a flowchart of an input method according to an embodiment of the present application. As shown in FIG. 5, the input method provided in this embodiment includes step S501 and step S502.

In S501, image information of the biometric input on the display interface of the electronic device is detected.

In S502, based on the detected image information of the biometric, the character information corresponding to the first position of the biometric displayed on the display interface is determined.

In an embodiment, the biometric features may include at least one of the following: a fingerprint, a palm print, an eye print, and a lip print.

In an embodiment, the first location can include a central location. However, this application is not limited thereto. In other embodiments, the first position may also be other set positions, such as a position with the highest fingerprint density, a ridge bifurcation position of the fingerprint, and a ridge node position of the fingerprint.

In an embodiment, the method may further include: detecting, in a case that the image information of the biometric is not turned on, the touch region information of the biometric input on the display interface of the electronic device.

In an embodiment, when the display interface includes the unlocking interface or the password verification interface, after S502, the method may further include:

Comparing the detected image information of the biometric and the character information determined according to the image information of the biometric with a preset password template; wherein the password template includes a biometric template and character information corresponding to the biometric template;

When the image information of the detected biometric is matched with the biometric template, and the character information determined according to the image information of the biometric matches the character information corresponding to the biometric template in the password template, the password input is confirmed to be correct.

In an embodiment, when the display interface includes a password setting interface, after S502, the method may further include: storing image information of the detected biometric and character information determined according to the image information of the biometric, and The image information of the biometric and the character information are used as a password template.

The input method provided by the present application will be described below by taking a biometric as a fingerprint as an example.

FIG. 6 is a flowchart of an input method according to another embodiment of the present application. In this embodiment, the execution main body is described by taking the electronic device shown in FIG. 1 as an example.

As shown in FIG. 6, the input method provided by an embodiment of the present application includes step S601, step S602, and step S603.

In S601, the processor (such as a CPU) determines whether to start the fingerprint image recognition function according to the security level requirement of the interface displayed by the display; wherein, for the interface with high security level requirements, such as screen unlocking, bank payment, and important account login Such as the interface, the fingerprint image recognition function can be turned on; for a security level requiring a general interface, such as a dialing interface, a browsing interface, a game operation interface, etc., it is generally not necessary to enable the fingerprint image recognition function. In an embodiment, the electronic device may provide default settings, or the user may also set the security level requirements of the interface according to his own needs.

In S602, according to the instruction of the processor, the fingerprint sensor turns on the fingerprint image recognition function, detects the fingerprint image information input on the interface, and calculates the coordinates of the touch center position in the fingerprint image region according to the fingerprint image information, and the processor is based on the touch center position. The coordinates of the coordinates can be determined to correspond to the character information displayed at that position on the display interface. For example, the fingerprint sensor can detect the fingerprint image in accordance with the detection mode shown in FIG. 4(a).

In S603, if the fingerprint image recognition function is not required to be turned on, the fingerprint sensor turns off the fingerprint image recognition function, does not detect the fingerprint image, detects only the fingerprint touch area, and calculates the touch position information. For example, the fingerprint sensor can be detected in accordance with the detection mode shown in FIG. 4(b).

FIG. 7 is a flowchart of another example of an input method provided by another embodiment of the present application. In this embodiment, the execution main body is described by taking the electronic device shown in FIG. 1 as an example. In this embodiment, when the fingerprint sensor turns on the fingerprint image recognition function, the user can perform password preset and matching unlock processing.

As shown in FIG. 7, the input method provided by another embodiment of the present application includes step S701, step S702, step S703, and step S704.

In S701, a password template is preset. The display of the electronic device may display a password setting interface, and prompt the user to detect the fingerprint image information when the password is preset; after the fingerprint sensor of the electronic device detects the fingerprint image information of the user, calculate the fingerprint image according to the fingerprint image information. The coordinates of the touch center position, the processor determines the character information corresponding to the coordinate on the display interface; the processor instructs the memory to store the entered fingerprint image information (as a fingerprint template) and the calculated corresponding character information as a password template.

In this step, the user can preset the password in the following two ways: The first method is to input the fingerprint template character by character. After the first character and the corresponding fingerprint image are collected, the next character and the corresponding fingerprint image are collected. Until the password is collected; the second way is to continuously enter all the characters, and then repeat the input until the fingerprint image corresponding to all characters is collected. In the above process, if it is detected that the fingerprints entered by the same character are not the same finger, the prompt is changed to the finger that is initially entered; or the fingerprints that are entered multiple times are inconsistent, so as to ensure that the password is preset multiple times during the input process. The fingerprint corresponding to the same character belongs to the same finger. If all characters and fingerprints are successfully collected, the password preset operation is completed.

In S702, when the display interface of the electronic device is the unlocking interface or the password verification interface, that is, when the user inputs a password for verification, the user can press the corresponding finger on the corresponding character according to the preset fingerprint. Wherein, when the user presses the character, the prompt position of the fingerprint may appear at the character position, prompting the user to input with the correct finger. Similar to the password template preset process, the character information is corresponding to the touch center position calculated based on the detected fingerprint image.

In S703, after receiving the input fingerprint image and the calculated character information, the processor of the electronic device compares with the password template stored in the memory; if the detected fingerprint image and the corresponding character information match successfully, then The password is correct and the verification is passed. If one of the two matches is unsuccessful, the password is incorrect. In an embodiment, the upper limit of the number of erroneous inputs can be set. If the number of consecutive erroneous input exceeds the preset upper limit, the password cannot be continuously entered for a period of time.

In S704, if the above password verification is successful, the processor may send an instruction to perform a response operation. In the process of inputting a password, if the processor determines that the input fingerprint image information and the character information match successfully, the fingerprint template in the password template can be continuously improved according to the input fingerprint image information, so that the subsequent recognition is faster and more accurate.

In this embodiment, as shown in FIG. 8( a ), the login password of the APP is set to a digital combination “150”, which in turn corresponds to the fingerprint A, the fingerprint B, and the fingerprint C. As shown in Figure 8(b), when the user logs in to the APP, you need to enter a password to unlock it. The entered characters and fingerprints are the same as the default password template. Figure 8(c) and Figure 8(d) show two operation cases in which the login fails. If one of the fingerprints and characters matches the preset password template, it cannot be unlocked successfully. In Figure 8(c), the characters entered match the password template, but the fingerprint corresponding to the character "1" does not match the password template, resulting in login failure. In Figure 8(d), the input fingerprints match the password template. However, the characters entered do not match the password template, causing the login to fail.
