Referring to fig. 1 to 4, an embodiment of the present invention provides a fingerprint acquisition method including:
s110, a pressed area 200 of the display screen 100 pressed is obtained.
S120, confirming an overlapping area 400 of the pressing area 200 and the fingerprint recognition area 300 of the display screen 100.
S130, in case that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold, controlling the overlapping area 400 to display with a first brightness, so that the fingerprint sensor 500 located below the display screen 100 collects the fingerprint in the overlapping area 400.
In the fingerprint acquisition method of the embodiment of the application, under the condition that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlapping area 400 is controlled to emit light with the first brightness, so that not only can the fingerprint sensor 500 successfully realize fingerprint identification, but also the area of the fingerprint identification area 300 which is not covered by a finger does not emit light and the overlapping area 400 which emits light is shielded, thereby reducing the direct incidence of light into human eyes for fingerprint identification as much as possible, reducing the stimulation of the human eyes to the light, and improving the user experience.
In the embodiment of the present application, the material of the display screen 100 is not limited, the display screen 100 may be an OLED display screen or a Micro LED display screen, the OLED has a self-luminous characteristic, the display screen 100 may also be an LCD display screen, and the LCD display screen needs to have a backlight 600 below the display screen 100. Thus, different requirements can be met. The fingerprint sensor 500 according to the embodiment of the present application is an optical fingerprint sensor.
Specifically, in one application scenario, when the user needs to wake up the screen, the user presses a finger on the screen to form the pressing area 200, and the fingerprint sensor 500 only recognizes the fingerprint when the finger is pressed on the fingerprint recognition area 300.
Illustratively, the pressing area 200 and the fingerprint identification area 300 of the display screen 100 form an overlapping area 400, when the area of the overlapping area 400 is less than or equal to 50% of the area of the fingerprint identification area 300, if the fingerprint sensor 500 is activated, the fingerprint sensor 500 collects less fingerprint data, and cannot obtain valid fingerprint data, and the collected fingerprint data cannot be matched with the fingerprint template, so that when the area of the overlapping area 400 is smaller, the fingerprint identification of the fingerprint sensor 500 is not triggered.
Only when the area of overlap area 400 is greater than 50% of the area of fingerprint identification area 300, fingerprint sensor 500 can gather more fingerprint data, and at this moment, overlap area 400 shows with first luminance, and the light irradiation user finger of overlap area 400 outgoing reflects fingerprint sensor 500 to the finger for fingerprint sensor 500 gathers user's fingerprint data, and under the condition that fingerprint data and fingerprint template match, can trigger display screen 500 and awaken up and bright the screen. Due to the design, the condition that a user mistakenly touches the fingerprint identification area 300 to cause screen lightening can be avoided, the working time of the fingerprint sensor 500 can be shortened, and the power consumption is reduced.
In step S110, it is understood that there is a sensor in the display screen 100 to receive the pressing, and when the display screen 100 is pressed, the sensor receives a signal and determines the specific location and size of the pressed region, thereby identifying the location and area of the pressed region 200 on the display screen 100.
In step S120, the fingerprint identification area 300 of the display screen 100 may be a region having an area slightly larger than that of a finger, and the shape of the fingerprint identification area 300 may be a square, a circle, or an ellipse. In the embodiment of the present application, the shape of the fingerprint identification area 300 is not limited. The position of the fingerprint identification area 300 is not limited, and may be located at a lower part in the middle of the display screen 100, or may be located in the middle of the bottom of the display screen 100, the lower right corner of the bottom, or other areas.
In step S130, when the threshold of the area ratio of the overlapping area 400 to the fingerprint identification area 300 is set to 50%, that is, the area of the overlapping area 400 is less than or equal to 50% of the area of the fingerprint identification area 300, the display screen 100 does not trigger the corresponding function.
When the area of the overlap area 400 is greater than 50% of the area of the fingerprint identification area 300, the overlap area 400 is displayed with a first brightness to illuminate the user's finger fingerprint, facilitating the fingerprint sensor 500 below the fingerprint identification area 300 to capture the fingerprint in the overlap area 400. The threshold of the area ratio of the overlap area 400 to the fingerprint identification area 300 is not limited, and may be set to other values, such as 55%, 60%, etc.
Referring to fig. 1, 3 and 5, in some embodiments, the fingerprint identification area 300 includes a first area 320, and the step 120 of confirming the overlap area 400 of the pressing area 200 and the fingerprint identification area 300 of the display screen 100 includes:
s121, forming a second region 220 with the center of the pressing region 200 as the center, the second region 220 being a regular-shaped region, the area of the second region 220 being smaller than or equal to the area of the first region 320;
s122, the intersection region of the first region 320 and the second region 220 is regarded as the overlap region 400.
Therefore, when the fingerprint identification device is used by a user, the fingerprint identification can accurately detect the fingerprint of the user.
Specifically, in step S121, it is understood that the pressing area 200 formed when the user' S finger presses the display screen 100 is generally irregular in shape, and for convenience of calculation, the second area 220 having a regular shape is formed centering on the center of the pressing area 200. For example, the shape of the second region 220 may be a regular shape such as a circle, a square, a pentagon, an ellipse, and the like. The center of the pressing area 200 is the geometric center or the geometric center of gravity of the outline of the pressing area 200.
The fingerprint identification area 300 includes a first area 320, and the shape of the first area 320 may be a regular shape such as a circle, a square, an ellipse, and the like. The first region 320 enables a user to actively press a finger against the first region 320 when pressing, such that the first region 320 and the second region 220 may coincide.
In step S122, during the actual pressing process, the first area 320 and the second area 220 cannot completely overlap due to different sizes of fingers, different holding manners, and the like. The intersection of the first area 320 and the second area 220 may be used as the overlap area 400, and a threshold value of the area ratio of the overlap area 400 to the fingerprint identification area 300 may be set.
Referring to fig. 1, 3 and 6, in some embodiments, the fingerprint identification area 300 includes a complementary set area 310 that does not overlap with the compression area 200, and the fingerprint acquisition method includes:
s140, when the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold, the complementary set area 310 is controlled to display with a second brightness, which is less than the first brightness.
Therefore, the situation that when a user uses the device at night, the brightness of the complementary collection area 310 is too high, human eyes are stimulated by light is avoided, and user experience is improved.
Specifically, in step S140, it can be understood that the fingerprint identification area 300 and the pressing area 200 are not completely overlapped when the user presses, that is, the first area 320 and the second area 220 cannot be completely overlapped, and a part where the fingerprint identification area 300 and the pressing area 200 are not overlapped is the complementary set area 310. The complementary set area 310 is displayed with the second brightness, so that the user can find the position of the fingerprint identification area 300 to press again, and the situation that the brightness of the first brightness is too strong, so that human eyes are stimulated by light is avoided. In some embodiments, the second brightness may be zero, and the user may find the location of the fingerprint recognition area 300 by himself or herself, so that the user may protect his or her eyes at night or in dark use. In addition, the complementary set area 310 with the second brightness may ensure that the fingerprint sensor 500 has enough brightness to capture the fingerprint in the offset area when the finger of the user is offset.
Referring to fig. 1, 3 and 7, in some embodiments, before acquiring the pressed area 200 of the display screen 100, the fingerprint acquisition method includes:
s150, acquiring the state of the display screen 100 when the display screen 100 is pressed;
s160, when the display screen 100 is in the bright state, the fingerprint identification area 300 is controlled to be displayed at a third brightness, and the third brightness is smaller than the first brightness.
Therefore, the fingerprint unlocking function can be effectively used by the user when the user is on the bright screen.
Specifically, in step S150, the user may wake up the display screen 100 by pressing a key or double-clicking the display screen 100, and the display screen 100 may be in a screen-locked state until the necessary time, weather, and some necessary information are displayed. In some embodiments, the display screen 100 in the lock screen state may also present the fingerprint identification area 300 in the form of a pattern, and when the user needs to unlock, the user may press the pattern to complete the unlocking. When the user presses the display screen 100, the display screen 100 can acquire the state of the display screen 100.
In step S160, the user presses the fingerprint identification area 300 in the bright screen state, and since the display screen 100 itself is in the full screen bright screen state, the area outside the fingerprint identification area 300 provides a certain degree of brightness, so that the third brightness is not particularly strong. And thus the third luminance is less than the first luminance.
Referring to fig. 1, 3 and 8, in some embodiments, the fingerprint acquisition method includes:
s170, in case that the area ratio of the overlap area 400 to the fingerprint identification area 300 is less than or equal to the threshold, controlling the fingerprint identification area 300 to keep displaying at the third brightness.
So, both guarantee that the user can effectively use fingerprint unblock function, avoided the user to accomplish the fingerprint identification action when pressing again, lead to luminance injury user's eyes.
Specifically, in step S170, it can be understood that when the user presses the fingerprint identification region 300, the area ratio of the overlap region 400 to the fingerprint identification region 300 is less than or equal to the threshold value. At this time, the display screen 100 is not lit and cannot be unlocked, but controls the fingerprint identification area 300 to remain displayed at the third brightness. The user may observe the third brightness of the complementary set region 310, move the finger so that the fingerprint identification region 300 coincides with the pressing region 200, and finally make the area ratio of the overlapping region 400 to the fingerprint identification region 300 larger than the threshold value.
Referring to fig. 1, 3 and 9, in some embodiments, in the case that the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold, the controlling the overlap area 400 to display at the first brightness (step S130) includes:
s131, if the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold, controlling the overlap area 400 to display with the first brightness when the display of the next frame is switched.
Thus, fingerprint identification can be completed quickly.
Specifically, in step S131, the display screen 100 changes the brightness of each region by way of refresh. Refreshing of the display screen 100 refers to the electron beam repeatedly scanning the image on the screen, and the screen brightness of the next frame can be changed given different electrical signals.
Illustratively, initially, the display screen 100 is in a dark screen state, and a user's finger presses the display screen 100 to form a pressing area 200, and the pressing area 200 overlaps an overlapping area 400 of the fingerprint identification area 300 of the display screen 100. The threshold may be 50%, and when the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than 50%, the display screen 100 switches the next frame to control the overlap area 400 to display at the first brightness, control the complementary set area 310 to display at the second brightness, and the fingerprint sensor 500 collects the fingerprint information of the user, and finally completes the wake-up and unlocks the display screen 100 after checking the fingerprint information with the stored information.
Referring to fig. 1, 4 and 10, in some embodiments, in the case that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold, the controlling the overlapping area 400 to display at the first brightness (step S130) includes:
s132, under the condition that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is larger than a threshold value, controlling the display screen 100 to emit light so that the overlapping area 400 is displayed with first brightness; or the like, or, alternatively,
s133, the backlight 600 disposed below the display screen 100 is controlled to emit light so that the overlap area 400 is displayed at the first luminance.
Thus, it is ensured that a variety of display screens 100 can use the fingerprint recognition method of the present application.
Specifically, in step S132, the display screen 100 may be an OLED display screen or a Micro LED display screen, and the OLED display screen is an organic light emitting diode, and is a self-luminous material without the backlight 600. When the user presses the display screen 100 and the area ratio of the overlap area 400 to the fingerprint identification area 300 is larger than the threshold value, the OLED display screen 100 is controlled to self-emit light so that the overlap area 400 is displayed at a first brightness.
In step S133, the display screen 100 may be an LCD display screen, which cannot self-emit light, and a backlight 600 must be provided to illuminate the user' S finger. When the user presses the display screen 100 and the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold value, the backlight 600 disposed below the display screen 100 is controlled to emit light so that the overlap area 400 is displayed at the first brightness.
Referring to fig. 1, 3 and 11, in some embodiments, in the case that the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold, the controlling the overlap area 400 to display at the first brightness (step S130) includes:
s134, controlling the overlapping area 400 to be displayed at a first sub-brightness when the area ratio of the overlapping area 400 to the fingerprint identification area 300 is larger than a threshold value and the ambient brightness is smaller than a preset brightness;
s135, when the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold and the ambient brightness is greater than or equal to the preset brightness, controlling the overlapping area 400 to display with a second sub-brightness, where the first brightness includes a first sub-brightness and a second sub-brightness, and the first sub-brightness is less than the second sub-brightness.
In this way, the overlapping area 400 can protect the eyes of the user in various situations by subdividing the brightness under different conditions.
Specifically, in step S134, the display screen 100 may further include an optical sensor for detecting the brightness near the display screen 100, so that the brightness may be compared with the preset brightness. Illustratively, in the case of dark light at night and the ambient brightness is less than the preset brightness. Because the user's eyes have adapted to the dark state, the pupillary dispersion increases the amount of light entering the eye as much as possible. At this time, the user presses the fingerprint to unlock the display screen 100, and the display screen 100 itself or a large amount of light rays of the complementary region 310 enter the eyes of the user when unlocking, thereby causing damage to the eyes of the user. When there is an optical sensor, the user presses the display screen 100, and the optical sensor first collects the ambient brightness and compares it with a preset brightness. When it is detected that the ambient brightness is less than the preset brightness and the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlap area 400 is displayed with a first sub-brightness. The brightness of the first sub-brightness is small, the first sub-brightness is reduced on the premise that the fingerprint sensor 500 collects fingerprints of a user, and eyes of the user are protected.
In step S135, for example, in the case that the light is sufficient in the daytime and the ambient brightness is greater than or equal to the preset brightness. As the user's eyes have adapted to the bright state, the pupillary constriction minimizes the amount of light entering the eye. At this time, when the user presses the fingerprint to unlock the display screen 100, the brightness of the display screen 100 itself or the complementary set area 310 during unlocking is insufficient, so that the user cannot distinguish whether the display screen 100 displays content. When there is an optical sensor, the user presses the display screen 100, and the optical sensor first collects the ambient brightness and compares it with a preset brightness. When it is detected that the ambient brightness is greater than or equal to the preset brightness and the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlap area 400 is displayed at a second sub-brightness. The second sub-brightness has a larger brightness, so that the fingerprint sensor 500 can accurately collect the fingerprint of the user on the premise of not damaging the eyes of the user.
Referring to fig. 1 and 12, a fingerprint acquisition apparatus 700 according to an embodiment of the present disclosure includes an acquisition module 710, a confirmation module 720, and a control module 730. The acquiring module 710 is used for acquiring the pressed area 200 of the display screen 100. The confirmation module 720 is used to confirm the overlapping area 400 of the pressing area 200 and the fingerprint recognition area 300 of the display screen 100. The control module 730 is configured to control the overlapping area 400 to be displayed with a first brightness when the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than a threshold value, so that the fingerprint sensor 500 located below the display screen 100 collects the fingerprint in the overlapping area 400.
In the fingerprint collection method of the embodiment of the application, under the condition that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlapping area 400 is controlled to emit light with the first brightness, so that not only can the fingerprint sensor 500 collect fingerprint images for fingerprint identification, but also light in an intersection area can be shielded to prevent the light in the intersection area from directly entering human eyes, stimulation of the human eyes by the light is reduced, and user experience is improved.
Thus, the design and management of the fingerprint acquisition device 700 can be facilitated through the modular operation.
Illustratively, when the user presses a finger on the fingerprint identification area 300 of the display screen 100 during use, the user refers to the actually pressed part as the pressed area 200, and the obtaining module 710 obtains the pressed area 200 of the display screen 100. The confirmation module 720 identifies whether the pressing area 200 overlaps the fingerprint identification area 300, and the overlapping portion is the overlapping area 400. When the area ratio of the overlap area 400 to the fingerprint identification area 300 is greater than the threshold, the control module 730 controls the overlap area 400 to be displayed with the first brightness. In this manner, the user's finger fingerprint may be illuminated to facilitate the fingerprint sensor 500 located below the display screen 100 to capture a fingerprint in the overlap area 400.
Referring to fig. 1 and 3, an electronic device 1000 according to an embodiment of the present disclosure includes a display screen 100, a fingerprint sensor 500, a memory 800, and a processor 900. The fingerprint sensor 500 is disposed under the display screen 100. The processor 900 is adapted to execute a computer program stored in the memory 800 to perform the fingerprint acquisition method described above.
In the fingerprint collection method of the embodiment of the application, under the condition that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlapping area 400 is controlled to emit light with the first brightness, so that not only can the fingerprint sensor 500 collect fingerprint images for fingerprint identification, but also light in an intersection area can be shielded to prevent the light in the intersection area from directly entering human eyes, stimulation of the human eyes by the light is reduced, and user experience is improved.
Therefore, the user can successfully complete the fingerprint identification function.
Specifically, the fingerprint recognition method ensures that the fingerprint sensor 500 can accurately collect the fingerprint of the user without damaging the eyes of the user. The processor 900 executes a computer program stored in the memory 800 to compare the captured fingerprint with a plurality of fingerprint information stored in the memory 800. If the coincidence rate of the collected fingerprint and the stored fingerprint information reaches the threshold value, the processor 900 unlocks the display screen 100, and if the coincidence rate of the collected fingerprint and the stored fingerprint information does not reach the threshold value, the processor 900 can control the electronic device 1000 to emit vibration to remind the user.
The electronic device 1000 according to the embodiment of the present application may be a mobile terminal device such as a mobile phone and a tablet computer, or may be a device having the display screen 100 such as a game device, a vehicle-mounted computer, and a notebook computer. In the embodiment of the present application, the specific type of the electronic device 1000 is not limited, as long as the display screen 100 and the fingerprint sensor 500 of the embodiment of the present application are included, and the unlocking of the device is realized by using the above fingerprint identification method, so as to meet different requirements.
Referring to fig. 1, a readable storage medium 800 storing a computer program according to an embodiment of the present disclosure, when the computer program is executed by one or more processors 800, implements the fingerprint capturing method described above.
In the fingerprint collection method of the embodiment of the application, under the condition that the area ratio of the overlapping area 400 to the fingerprint identification area 300 is greater than the threshold value, the overlapping area 400 is controlled to emit light with the first brightness, so that not only can the fingerprint sensor 500 collect fingerprint images for fingerprint identification, but also light in an intersection area can be shielded to prevent the light in the intersection area from directly entering human eyes, stimulation of the human eyes by the light is reduced, and user experience is improved.
