Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.
The technical scheme of the embodiment of the application can be applied to various electronic devices.
Such as portable or mobile computing devices, e.g., smart phones, laptops, tablets, gaming devices, etc., and other electronic devices, e.g., electronic databases, automobiles, Automated Teller Machines (ATMs), etc. However, the present embodiment is not limited thereto.
The technical scheme of the embodiment of the application can be used for the biological feature recognition technology. The biometric technology includes, but is not limited to, fingerprint recognition, palm print recognition, iris recognition, face recognition, and living body recognition. For convenience of explanation, the fingerprint identification technology is described as an example below.
The technical scheme of the embodiment of the application can be used for the under-screen fingerprint identification technology and the in-screen fingerprint identification technology.
Fingerprint identification technique is installed in the display screen below with fingerprint identification module under the screen to realize carrying out the fingerprint identification operation in the display area of display screen, need not set up the fingerprint collection region in the positive region except that the display area of electronic equipment. Specifically, the fingerprint identification module uses the light that returns from the top surface of electronic equipment's display module to carry out fingerprint response and other response operations. This returned light carries information about an object (e.g., a finger) in contact with the top surface of the display assembly, and the fingerprint recognition module located below the display assembly collects and detects this returned light to perform underscreen fingerprint recognition. Among other things, the design of the fingerprint recognition module may be such that the desired optical imaging is achieved by appropriately configuring the optical elements used to collect and detect the returned light.
Correspondingly, (In-display) fingerprint identification technique means installs inside the display screen fingerprint identification module or partial fingerprint identification module In the screen to realize carrying out the fingerprint identification operation In the display area of display screen, need not set up the fingerprint collection region In the positive region except that the display area of electronic equipment.
Fig. 1 and fig. 2 are schematic diagrams illustrating an electronic device 100 to which an off-screen fingerprint identification technology may be applied, where fig. 1 is a schematic diagram of a front side of the electronic device 100, and fig. 2 is a schematic diagram of a partial cross-sectional structure of the electronic device 100 shown in fig. 1.
As shown in fig. 1 and 2, the electronic device 100 may include a display 120 and a fingerprint identification module 140.
The display 120 may be a self-luminous display employing display units having self-luminous properties as display pixels. For example, the display screen 120 may be an Organic Light-Emitting Diode (OLED) display screen or a Micro-LED (Micro-LED) display screen. In other alternative embodiments, the Display 120 may also be a Liquid Crystal Display (LCD) or other passive light emitting Display, which is not limited in this embodiment of the present application.
In addition, the display screen 120 may also be specifically a touch display screen, which not only can perform image display, but also can detect a touch or pressing operation of a user, thereby providing a human-computer interaction interface for the user. For example, in one embodiment, the electronic device 100 may include a Touch sensor, which may be embodied as a Touch Panel (TP), which may be disposed on a surface of the display screen 120, or may be partially or wholly integrated within the display screen 120, so as to form the Touch display screen.
In particular, the fingerprint identification module 140 may include a fingerprint sensor chip having an optically sensitive array (hereinafter also referred to as an optical fingerprint sensor). The optical sensing array includes a plurality of optical sensing units, and each optical sensing unit may specifically include a photodetector or a photosensor. Alternatively, the fingerprint identification module 140 may include a Photo detector array (or referred to as a Photo detector array or a Photo sensor array), which includes a plurality of Photo detectors distributed in an array.
As shown in fig. 1, the fingerprint identification module 140 may be disposed in a local area below the display screen 120, so that the fingerprint collection area (or detection area) 130 of the fingerprint identification module 140 is at least partially located in the display area 102 of the display screen 120.
Of course, in other alternative embodiments, the fingerprint identification module 140 may be disposed at other positions, such as the side of the display screen 120 or the edge non-transparent area of the electronic device 100. In this case, the optical signal of at least a part of the display area of the display screen 120 can be guided to the fingerprint identification module 140 through the optical path design, so that the fingerprint collection area 130 is actually located in the display area of the display screen 120.
In some embodiments of the present application, the fingerprint identification module 140 may only include one fingerprint sensor chip, and the area of the fingerprint collection area 130 of the fingerprint identification module 140 is small and the position is fixed at this time, so the user needs to press the finger to a specific position of the fingerprint collection area 130 when performing fingerprint input, otherwise the fingerprint identification module 140 may not collect a fingerprint image and cause poor user experience.
In other embodiments of the present application, the fingerprint identification module 140 may specifically include a plurality of fingerprint sensor chips; the plurality of fingerprint sensor chips can be arranged side by side in a splicing mode below the display screen 120, and sensing areas of the plurality of fingerprint sensor chips jointly form the fingerprint collecting area 130 of the fingerprint identification module 140. That is to say, the fingerprint collection area 130 of the fingerprint identification module 140 may include a plurality of sub-areas, and each sub-area corresponds to the sensing area of one of the fingerprint sensor chips, respectively, so as to extend the fingerprint collection area 130 of the optical fingerprint module 130 to the main area of the lower half of the display screen, that is, to the area that the finger presses conventionally, thereby realizing the blind-touch type fingerprint input operation. Alternatively, when the number of fingerprint sensor chips is sufficient, the fingerprint detection area 130 may also be extended to half or even the entire display area, thereby enabling half-screen or full-screen fingerprint detection.
Fig. 3 is a schematic flow chart diagram of a method 200 of guiding a user to register a fingerprint according to an embodiment of the present application. It should be understood that the method 200 may be performed by the electronic device shown in fig. 1 or fig. 2, or may be performed by any device including a display screen and a fingerprint sensor chip, which is not limited in this application. For ease of understanding, the method is described below as being performed by an electronic device as an example.
As shown in fig. 3, the method 200 may include:
s210, the electronic equipment displays a first image in a display area of the display screen according to a first fingerprint acquisition area where a first fingerprint sensor chip of the at least one fingerprint sensor chip is located, wherein the first image is used for indicating a pressing position of a user when the user registers a fingerprint.
S210, the electronic equipment transforms the position of the first image according to the first fingerprint acquisition area so that the first fingerprint sensor chip can acquire fingerprint information of different positions of the finger of the user.
Specifically, after the electronic device displays the first image based on the position of the first fingerprint collection area, the user presses a finger on the position of the first image in the display area, so that a first fingerprint input operation is realized. After the electronic equipment transforms the display position of the first image based on the position of the first fingerprint acquisition area, the user presses the finger on the position of the first image in the display area again, and therefore the second fingerprint input operation is achieved. Because the position of the first fingerprint acquisition area in the display area is fixed and unchanged, the position of the first image is changed to guide the user to press different positions in the display area, so that the fingerprint information acquired by the first fingerprint sensor chip can comprise the fingerprint information of different positions of the finger of the user when the user presses the display screen at every time, further, the situation that the user needs to change the position of the finger pressing the display screen continuously in the fingerprint registering process is avoided, and the fingerprint registering speed and the user experience can be effectively improved.
In some embodiments of the application, when the display screen is pressed and the pressing force is greater than or equal to the preset threshold value, the electronic device displays the first image based on the first fingerprint acquisition area, and changes the display position of the first image after a user inputs a fingerprint, so that acquisition of fingerprint information of different positions of a finger of the user is realized.
It should be understood that the first fingerprint sensor is not particularly limited in the embodiments of the present application.
For example, the first fingerprint sensor chip may be a specific fingerprint sensor chip of the at least one fingerprint sensor chip. At this time, since the position of the first fingerprint acquisition area where the first fingerprint sensor chip is located in the display area is fixed, the position for displaying the first image for the first time in one fingerprint registration process may be a preset position. For example, the first image may be displayed for the first time during a fingerprint registration process in any one of a left area, a right area, a top area, and a bottom area of the first fingerprint collection area.
For another example, the first fingerprint sensor chip may be a fingerprint sensor chip pressed by a user for the first time or a fingerprint sensor chip which collects fingerprint information for the first time. Specifically, when the display screen is pressed by the user, the electronic device determines a first fingerprint sensor according to the pressing position, and determines a target position based on the position of a first fingerprint acquisition area where the first sensor is located in the display area; then, the electronic device displays the first image on the target position.
In the above S220, the electronic device may transform the position of the first image according to a preset order according to the first fingerprint collection area. For example, the electronic device may change the display position of the first image in a counterclockwise direction according to the first fingerprint collection area. For another example, the electronic device may shift the display position of the first image in a clockwise direction.
In some embodiments of the present application, the at least one fingerprint sensor chip comprises only the first fingerprint sensor chip. At this time, the electronic device may transform the position of the first image in the following preset order:
a left region, a right region, a top region, and a bottom region of the first fingerprint acquisition region.
Fig. 4 to 7 are schematic views of a process in which an electronic device including only one fingerprint sensor chip guides a user to register a fingerprint. The fingerprint acquisition area of the electronic device comprises only the first fingerprint acquisition area 131 where the first fingerprint sensor is located.
In the process of registering a fingerprint, as shown in fig. 4, the electronic device first displays the first image 160 in the right area of the first fingerprint acquisition area 131 where the first fingerprint sensor chip is located, so as to guide a user to press the right area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can acquire the left fingerprint information of the user's finger 170. Then, as shown in fig. 5, the electronic device redisplays the first image 160 in the left area of the first fingerprint acquisition area 131 to guide the user to press the left area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can collect right fingerprint information of the user's finger 170. Further, as shown in fig. 6, the electronic device redisplays the first image 160 at the top area of the first fingerprint acquisition area 131 to guide the user to press the top area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can acquire the bottom fingerprint information of the user's finger 170. Finally, as shown in fig. 7, the electronic device redisplays the first image 160 in the bottom area of the first fingerprint acquisition area 131 to guide the user to press the bottom area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can collect the top fingerprint information of the user's finger 170.
By splicing the fingerprint information acquired by the first fingerprint sensor chip in the 4 acquisition processes, the electronic equipment can obtain the complete information of the finger of the user.
It should be understood that fig. 4-7 are only examples of the present application and should not be construed as limiting the present application.
For example, in other alternative embodiments, the electronic device may change the display position of the first image less or more than 3 times. For example, the electronic device may transform the display position of the first image in the following order: the first fingerprint acquisition area comprises a left side area, an upper left corner area, a right side area, an upper right corner area, a top area, a bottom area, a lower left corner area and a lower right corner area. Alternatively, the electronic device may only alternate between the left and right regions of the first fingerprint acquisition region.
For another example, the electronic device may shift the display position of the first image in any predetermined order in the left area, the right area, the top area, and the bottom area of the first fingerprint acquisition area.
In other embodiments of the present application, the electronic device may include a plurality of fingerprint sensor chips, and the plurality of fingerprint sensor chips may be arranged side by side to be spliced into a fingerprint sensor chip assembly. At this time, the electronic device may transform the position of the first image in the following preset order:
the fingerprint sensor chip comprises a first fingerprint acquisition area, a second fingerprint acquisition area, a middle area of the first fingerprint acquisition area, a top area of the first fingerprint acquisition area and a bottom area of the first fingerprint acquisition area, wherein the second fingerprint acquisition area is located in a second fingerprint acquisition area of a second fingerprint sensor in the at least one fingerprint sensor chip.
Fig. 8 to 11 are schematic diagrams of a process in which an electronic device including a plurality of fingerprint sensor chips guides a user to register a fingerprint. The fingerprint collection area of the electronic device may include a first fingerprint collection area 131 where the first fingerprint sensor chip is located, a second fingerprint collection area 132 where the second fingerprint sensor chip is located, a third fingerprint collection area 133 where the third fingerprint sensor chip is located, and a fourth fingerprint collection area 134 where the fourth fingerprint sensor chip is located.
In the process of registering a fingerprint, as shown in fig. 8, the electronic device first displays the first image 160 in the middle area between the first fingerprint collection area 131 and the second fingerprint collection area 132 to guide a user to press the middle area between the first fingerprint collection area 131 and the second fingerprint collection area; at this time, the first fingerprint sensor chip can acquire right side fingerprint information of the finger 170 of the user, and the second fingerprint sensor chip can acquire left side fingerprint information of the finger 170. Then, as shown in fig. 9, the electronic device redisplays the first image 160 in the middle area of the first fingerprint acquisition area 131 to guide the user to press the middle area of the first fingerprint acquisition area 131; the first fingerprint sensor is now able to capture fingerprint information of the middle position of the user's finger 170. Further, as shown in fig. 10, the electronic device redisplays the first image 160 at the top area of the first fingerprint acquisition area 131 to guide the user to press the top area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can acquire the bottom fingerprint information of the user's finger 170. Finally, as shown in fig. 11, the electronic device redisplays the first image 160 in the bottom area of the first fingerprint acquisition area 131 to guide the user to press the bottom area of the first fingerprint acquisition area 131; at this time, the first fingerprint sensor chip can collect the top fingerprint information of the user's finger 170.
Through right first fingerprint sensor chip with the fingerprint information that second fingerprint sensor chip gathered at the first acquisition in-process, and the fingerprint information that first fingerprint sensor chip gathered at remaining 3 acquisition in-processes splices, electronic equipment can obtain the complete information of user's finger.
Similarly, fig. 8 to 11 are also merely examples of the present application and should not be construed as limiting themselves.
For example, in other alternative embodiments, the electronic device may subsequently alternate between the middle position, the top region, and the bottom region of the second fingerprint acquisition region after displaying the first image in the position shown in FIG. 8. For another example, the number of times the display position of the first image is changed by the electronic device may be less than or more than 3 times.
For another example, the electronic device may change the display position of the first image in any predetermined order in a middle area of the first fingerprint collection area and a second fingerprint collection area where a second fingerprint sensor of the at least one fingerprint sensor chip is located, in a middle area of the first fingerprint collection area, in a top area of the first fingerprint collection area, and in a bottom area of the first fingerprint collection area.
It should be understood that the embodiment of the present application does not specifically limit the style of the first image 160. For example, the first image 160 may be a logo pattern or a prompt box. The identification pattern may be a fingerprint picture or other type of image. The shape of the prompt box can be regular such as circular, rectangular or rectangular, and the shape of the prompt box can also be irregular. As shown in fig. 4 to 11, the prompt box may be a square prompt box.
It should also be appreciated that the area of the first image 160 within the display area of the display screen may be greater than or less than or even equal to the area of the first fingerprint acquisition area 131 within the display area. Furthermore, the first image 160 may partially overlap the first fingerprint acquisition area 131, or may completely overlap the first fingerprint acquisition area. The embodiment of the present application does not limit this.
It should also be understood that, when the electronic device displays the first image 160 in the display area for multiple times, the first image 160 may be partially overlapped or not overlapped in the display area at different display positions, and this is not particularly limited in this application.
In some embodiments of the present application, a display screen of the electronic device may include a luminescent layer, which may include a fingerprint illumination area. The fingerprint acquisition area is used for illuminating the fingerprint acquisition area of the fingerprint sensor chip of the electronic equipment. For example, when the fingerprint acquisition area is pressed by the user, the illumination of the light emitting pixels within the fingerprint illumination area may illuminate at least the first fingerprint acquisition area 131. Referring to the drawings, when the electronic device displays the first image 160 in the position shown in fig. 8, the fingerprint illumination area may illuminate the first fingerprint acquisition area 131 and the second fingerprint acquisition area 132 simultaneously. Of course, the electronic device may also illuminate the fingerprint collection areas where all the fingerprint sensor chips are located, and the embodiment of the electronic device is not particularly limited thereto.
Specifically, the light beams emitted from the light-emitting pixels are reflected on the surface of the finger to form reflected light or scattered light is scattered inside the finger to form scattered light. Because ridges (ridges) and valleys (vally) of a fingerprint have different light reflection capacities, reflected light from the ridges and the valleys of the fingerprint have different light intensities, and the reflected light is received by the fingerprint sensor chip and converted into corresponding electric signals, namely fingerprint information, after passing through the display screen.
In other words, in the process of registering a fingerprint by a user, the user presses the display screen according to the display position of the first image 160 on the display screen 160, the screen lights up the light-emitting pixels (also called light spots) corresponding to the fingerprint collection area where the first image 160 intersects, and the fingerprint sensor chip of the electronic device collects the fingerprint information of the user by receiving the reflected light reflected by the fingerprint lines.
Of course, in other alternatives, the fingerprint sensor chip may also use an internal light source or an external light source to provide an optical signal for fingerprint detection and identification. In this case, the fingerprint sensor chip may be applied not only to a self-luminous display screen such as an OLED display screen but also to a non-self-luminous display screen such as a liquid crystal display screen or other passive luminous display screen.
In some embodiments of the present application, the method 200 may further comprise:
the electronic equipment displays a second image in a display area of a display screen of the electronic equipment, wherein the second image is used for displaying the fingerprint information collected when the display area is pressed by a user in the first image. Namely, when the user presses the display screen, the electronic device can synchronously display a fingerprint acquisition result, and the acquisition result can provide reference for whether the electronic device changes the display position of the first image. For example, as shown in fig. 4, assuming that the current display position of the first image is the right area of the first fingerprint collection area 131, the second image is used to display the left fingerprint information of the finger 170 of the user, and if the left fingerprint information of the finger 170 displayed by the second image is incomplete, the user may press the display screen again until the second image can completely display the left fingerprint information of the finger 170. Further, when the electronic device displays the first image 160 at the display position shown in fig. 5, the second image may be used to display only the right fingerprint information of the finger 170, or may be used to simultaneously display the right fingerprint information and the left fingerprint information previously collected by the electronic device, which is not specifically limited in this application.
In some embodiments of the present application, the method 200 may further comprise:
and when the second image is the fingerprint image of the whole finger, the electronic equipment stops displaying the first image. That is, the electronic device determines that the fingerprint collection operation in the fingerprint registration process is completed, and at this time, the electronic device may store the complete fingerprint image obtained after the stitching process as a fingerprint template in a memory of the electronic device, so as to facilitate the use of the fingerprint template in the subsequent fingerprint identification process.
The embodiment of the application also provides electronic equipment which can comprise the display screen and at least one fingerprint sensor chip.
With continued reference to fig. 2, the electronic device may include a display screen 120 and a fingerprint identification module 140, the fingerprint identification module 140 may include at least one fingerprint sensor chip, and the display area of the display screen 120 includes a fingerprint collection area of the at least one fingerprint sensor chip.
The display screen 120 is configured to display a first image in a display area of the display screen 120 according to a first fingerprint acquisition area where a first fingerprint sensor chip of the at least one fingerprint sensor chip is located, where the first image is used for only a pressing position when a user registers a fingerprint; the position of the first image is then transformed according to the first fingerprint acquisition area.
