A terminal device, also called a User Equipment (UE), is a device providing voice and/or data connectivity to a User, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and so on. Common terminals include, for example: the mobile phone includes a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and a wearable device such as a smart watch, a smart bracelet, a pedometer, and the like.
The embodiments of the present invention will be described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal device 100 according to an embodiment of the present invention, where the terminal device 100 includes: an application processor AP110, a touch display screen 120, an optical fingerprint module 130 and N light sources 140 disposed on the optical fingerprint module 130, where N is an integer greater than 1, the optical fingerprint module 130 is disposed under the touch display screen 120, wherein the AP110 is connected to the touch display screen 120 and the optical fingerprint module 130 through a bus 150,
the AP110 is configured to light M light sources of the N light sources, where light emitted by the M light sources is used to illuminate a fingerprint of a user, and M is a positive integer;
the optical fingerprint module 130 is configured to collect fingerprints of users irradiated by light emitted by the M light sources.
In an example, the N light sources correspond to N frequencies, the N light sources correspond to the N frequencies one to one, a distance between a light source and the touch display screen is inversely proportional to a frequency of the light source, and the N frequencies are different from each other.
Specifically, frequency versus wavelength: the speed of light is wavelength times frequency, and since the speed of light is fixed, the wavelength is inversely proportional to frequency, with higher frequencies the shorter the wavelength. Since the material has dispersion, the dispersion refers to a phenomenon that when light with different wavelengths passes through a lens (herein, referred to as a touch display screen), refractive indexes of the lens are different, and generally, the longer the wavelength is, the lower the refractive index of the lens is. The relationship between the focal length of the lens and the refractive index is as follows: focal length 1/[ (refractive index-1) ((1/r)1)–(1/r2))]It can be seen that when r is1And r2While fixed, the focal length is inversely proportional to the refractive index, the lower the refractive index the higher the focal length, and in sum, the higher the frequency, the shorter the wavelength, the higher the refractive index, the shorter the focal length, and vice versa. The focal length refers to the distance from the optical center of the lens (here, the touch screen) to the focal point of the light collection (i.e., the distance from the touch screen to the light source), so that the higher the frequency of the light source, the shorter the distance from the light source to the touch screen, and vice versa. Therefore, the distance between the light source and the touch display screen is determined according to the frequency of the light source, and the quality of the collected fingerprint image is further ensured.
In an example, the touch display screen includes a fingerprint acquisition area. The optical fingerprint module is arranged below the fingerprint input area. As shown in particular in fig. 2. The size and the position of the fingerprint acquisition area are not limited in the present invention.
In one example, N light sources correspond to N positions, the N light sources correspond to the N positions one-to-one, the abscissa of the N positions is different, and the ordinate of the N positions is different. For example, assuming that N is 3, the 3 light sources have: light source A, light source B and light source C, the frequency relation of these 3 light sources has: the frequency of light source B is higher than that of light source a, and the frequency of light source a is higher than that of light source C, and the 3 light sources are located as shown in fig. 2.
In an example, the terminal device further includes a motor 160 built in the optical fingerprint module 130, the motor 160 is connected to the N light sources 140, the N light sources 140 correspond to N positions, abscissa of the N positions is the same, and ordinate of the N positions is different.
For example, assuming that N is 3, the 3 light sources have: light source A, light source B and light source C, the frequency relation of these 3 light sources has: the frequency of light source B is higher than that of light source a, and the frequency of light source a is higher than that of light source C, and the corresponding positions of these 3 light sources are shown in fig. 3. It can be seen that for N light sources corresponding to N positions, the abscissa of the N positions is different, the ordinate of the N positions is different, the N light sources correspond to N positions, the abscissa of the N positions is the same, the ordinate of the N positions is different, and the area of the fingerprint identification module can be reduced.
Further, the AP110 is further configured to, before the M light sources 140 are turned on, place the M light sources 140 in M positions and place light sources other than the M light sources 140 in N-M positions by the motor 160; the abscissa of the M positions is different, the ordinate of the M positions is different, the N-M positions are different from the M positions, the abscissa of the N-M positions is the same, and the ordinate of the N-M positions is different.
Specifically, for example, assuming that N is 4, the 4 light sources include: light source a, light source B, light source C, and light source D, the initial positions of these 4 light sources are shown as (1) in fig. 4, assuming that M is 2, these 2 light sources are assumed to be light source a and light source D, in order to avoid that light sources that do not need to be lit block light sources that need to be lit, therefore, the terminal device uses the motor to position the light source A and the light source D at a first position and a second position, the abscissa of the first position is different from the abscissa of the second position, the ordinate of the first position is different from the ordinate of the second position, then, the light source B and the light source C are located at a third position and a fourth position, the first position, the second position, the third position and the fourth position are different from each other, the abscissa of the third position is the same as that of the fourth position, the ordinate of the third position is different from that of the fourth position, and the positions of all 4 light sources after adjustment are as shown in (2) in fig. 4.
In one example, the M light sources 140 are illuminated by the AP110 when a fingerprint image capture command is detected, and the AP110 is further configured to determine the M light sources 140 according to an importance priority of an application i sending the fingerprint image capture command. Therefore, the light source for collecting the fingerprint can be flexibly determined according to the important priority of the application.
In one example, the specific implementation of the AP110 determining the M light sources 140 according to the importance priority of the application i sending the fingerprint image capturing instruction is as follows:
when the important priority of the application i is smaller than a first preset priority, selecting M light sources with the frequency smaller than a preset frequency from the N light sources, wherein M is equal to 1;
when the important priority of the application i is greater than or equal to the first preset priority and less than a second preset priority, selecting M light sources with the frequency greater than or equal to the preset frequency from the N light sources, wherein M is equal to 1;
and when the important priority of the application i is greater than or equal to the second preset priority, selecting M light sources from the N light sources, wherein M is greater than 1.
For example, if the first predetermined priority is priority 2 and the second predetermined priority is priority 4, if the important priority of the application i is priority 1, it can be seen that the importance degree of the application i is relatively low, and in order to reduce power consumption, only 1 light source smaller than the predetermined frequency may be lit. If the importance priority of the application i is priority 3, it can be seen that the importance level of the application i is in a medium state, and in order to reduce power consumption and ensure that the collected fingerprints are clear, only 1 light source with a frequency greater than or equal to a preset frequency can be lighted. If the important priority of the application i is priority 5, it can be seen that the important degree of the application i is high, and in this case, the accuracy of fingerprint authentication is mainly guaranteed, so that the quality of the acquired fingerprint needs to be guaranteed to be good, and a plurality of light sources can be lighted at this time.
Further, the specific implementation manner of selecting M light sources 140 from the N light sources 140 by the AP110 is as follows: the terminal device determines a difference value X between the important priority of the application i and the second preset priority, and selects M light sources 140 from the N light sources 140 according to a mapping relation between the difference value between the important priority of the application I and the second preset priority and the light sources.
For example, assuming that N is 4, the mapping relationship between the difference and the light source is: 1 corresponds to 2 light sources, 2 corresponds to 2 light sources, 3 corresponds to 3 light sources, 4 corresponds to 3 light sources, and 5 corresponds to 4 light sources. Assuming that the important priority of the application i is priority 5, the second preset priority is priority 4, and the difference between the two is 1, the application i corresponds to 2 light sources. It should be noted that the frequency of the 2 light sources may be smaller or larger, and the present invention is not limited thereto.
Furthermore, each application corresponds to an important priority, and the important priority corresponding to each application is user-defined; or the importance priority corresponding to each application is determined by the AP110 according to the application attribute, for example, if the application attribute of the application a is unlocked, the importance priority corresponding to the application attribute is unlocked is the first priority, then the importance priority of the application a is the first priority, and if the application attribute is fingerprint payment, then the importance priority corresponding to the application attribute is fingerprint payment is the second priority, then the application attribute of the application B is fingerprint payment; alternatively, the importance priority corresponding to each application is determined by the AP110 according to the usage parameter of the application, for example, the usage parameter is a usage frequency, and a higher usage frequency indicates that the user information related to the application is more, and the corresponding importance priority is higher.
Therefore, in the scheme provided by the invention, the optical fingerprint module is internally provided with the plurality of light sources, and when the fingerprint image is collected, the light emitted by the light sources internally arranged in the optical fingerprint module is used for collecting the fingerprint image, so that the service life of the mobile phone screen is further ensured.
Referring to fig. 5, fig. 5 is a schematic flow chart of a fingerprint image collecting method according to an embodiment of the present invention, including an application processor AP, an optical fingerprint module, N light sources embedded in the optical fingerprint module, and a terminal device of a touch display screen, where N is an integer greater than 1, and the optical fingerprint module is disposed below the touch display screen, including the following steps:
s501, the terminal equipment lights M light sources in the N light sources, light emitted by the M light sources is used for irradiating fingerprints of users, and M is a positive integer.
In an example, the N light sources correspond to N frequencies, the N light sources correspond to the N frequencies one to one, a distance between a light source and the touch display screen is inversely proportional to a frequency of the light source, and the N frequencies are different from each other.
Specifically, frequency versus wavelength: the speed of light is wavelength times frequency, and since the speed of light is fixed, the wavelength is inversely proportional to frequency, with higher frequencies the shorter the wavelength. Since the material has dispersion, the dispersion refers to a phenomenon that when light with different wavelengths passes through a lens (herein, referred to as a touch display screen), refractive indexes of the lens are different, and generally, the longer the wavelength is, the lower the refractive index of the lens is. The relationship between the focal length of the lens and the refractive index is as follows: focal length 1/[ (refractive index-1) ((1/r)1)–(1/r2))]It can be seen that when r is1And r2While fixed, the focal length is inversely proportional to the refractive index, the lower the refractive index the higher the focal length, and in sum, the higher the frequency, the shorter the wavelength, the higher the refractive index, the shorter the focal length, and vice versa. The focal length refers to the distance from the optical center of the lens (here, the touch screen) to the focal point of the light collection (i.e., the distance from the touch screen to the light source), so that the higher the frequency of the light source, the shorter the distance from the light source to the touch screen, and vice versa. Therefore, the distance between the light source and the touch display screen is determined according to the frequency of the light source, and the quality of the collected fingerprint image is further ensured.
In an example, the touch display screen includes a fingerprint acquisition area. The optical fingerprint module is arranged below the fingerprint input area. As shown in particular in fig. 2. The size and the position of the fingerprint acquisition area are not limited in the present invention.
In one example, N light sources correspond to N positions, the N light sources correspond to the N positions one-to-one, the abscissa of the N positions is different, and the ordinate of the N positions is different. For example, assuming that N is 3, the 3 light sources have: light source A, light source B and light source C, the frequency relation of these 3 light sources has: the frequency of light source B is higher than that of light source a, and the frequency of light source a is higher than that of light source C, and the 3 light sources are located as shown in fig. 2.
In an example, the terminal device further includes a motor built in the optical fingerprint module, the motor is connected to the N light sources, the N light sources correspond to N positions, abscissa of the N positions is the same, and ordinate of the N positions is different.
For example, assuming that N is 3, the 3 light sources have: light source A, light source B and light source C, the frequency relation of these 3 light sources has: the frequency of light source B is higher than that of light source a, and the frequency of light source a is higher than that of light source C, and the corresponding positions of these 3 light sources are shown in fig. 3.
It can be seen that for N light sources corresponding to N positions, the abscissa of the N positions is different, the ordinate of the N positions is different, the N light sources correspond to N positions, the abscissa of the N positions is the same, the ordinate of the N positions is different, and the area of the fingerprint identification module can be reduced.
Further, the method further comprises:
before lighting the M light sources, the terminal device places the M light sources in M positions and places light sources other than the M light sources in N-M positions through the motor; the abscissa of the M positions is different, the ordinate of the M positions is different, the N-M positions are different from the M positions, the abscissa of the N-M positions is the same, and the ordinate of the N-M positions is different.
Specifically, for example, assuming that N is 4, the 4 light sources include: light source a, light source B, light source C, and light source D, the initial positions of these 4 light sources are shown in fig. 4(1), assuming that M is 2, these 2 light sources are assumed to be light source a and light source D, in order to avoid that light sources that do not need to be lit block light sources that need to be lit, therefore, the terminal device uses the motor to position the light source A and the light source D at a first position and a second position, the abscissa of the first position is different from the abscissa of the second position, the ordinate of the first position is different from the ordinate of the second position, then, the light source B and the light source C are located at a third position and a fourth position, the first position, the second position, the third position and the fourth position are different from each other, the abscissa of the third position is the same as that of the fourth position, the ordinate of the third position is different from that of the fourth position, and the positions of all 4 light sources after adjustment are shown in fig. 4 (2).
In one example, the M light sources are illuminated upon detection of a fingerprint image capture instruction, the method further comprising: and the terminal equipment determines the M light sources according to the important priority of the application i which sends the fingerprint image acquisition instruction. Therefore, the light source for collecting the fingerprint can be flexibly determined according to the important priority of the application.
In an example, the specific implementation manner of the terminal device determining the M light sources according to the application importance priority for sending the fingerprint image acquisition instruction is as follows:
when the important priority of the application i is smaller than a first preset priority, the terminal equipment selects M light sources with the frequency smaller than a preset frequency from the N light sources, wherein M is equal to 1;
when the important priority of the application i is greater than or equal to the first preset priority and less than a second preset priority, the terminal equipment selects M light sources with the frequency greater than or equal to the preset frequency from the N light sources, wherein M is equal to 1;
and when the important priority of the application i is greater than or equal to the second preset priority, the terminal equipment selects M light sources from the N light sources, wherein M is greater than 1.
For example, if the first predetermined priority is priority 2 and the second predetermined priority is priority 4, if the important priority of the application i is priority 1, it can be seen that the importance degree of the application i is relatively low, and in order to reduce power consumption, only 1 light source smaller than the predetermined frequency may be lit. If the importance priority of the application i is priority 3, it can be seen that the importance level of the application i is in a medium state, and in order to reduce power consumption and ensure that the collected fingerprints are clear, only 1 light source with a frequency greater than or equal to a preset frequency can be lighted. If the important priority of the application i is priority 5, it can be seen that the important degree of the application i is high, and in this case, the accuracy of fingerprint authentication is mainly guaranteed, so that the quality of the acquired fingerprint needs to be guaranteed to be good, and a plurality of light sources can be lighted at this time.
Further, the specific implementation manner of selecting M light sources from the N light sources by the terminal device is as follows: and the terminal equipment determines a difference value X between the important priority of the application i and the second preset priority, and selects M light sources from the N light sources according to the mapping relation between the difference value between the important priority of the application I and the second preset priority and the light sources.
For example, assuming that N is 4, the mapping relationship between the difference and the light source is: 1 corresponds to 2 light sources, 2 corresponds to 2 light sources, 3 corresponds to 3 light sources, 4 corresponds to 3 light sources, and 5 corresponds to 4 light sources. Assuming that the important priority of the application i is priority 5, the second preset priority is priority 4, and the difference between the two is 1, the application i corresponds to 2 light sources. It should be noted that the frequency of the 2 light sources may be smaller or larger, and the present invention is not limited thereto.
Furthermore, each application corresponds to an important priority, and the important priority corresponding to each application is user-defined; or the important priority corresponding to each application is determined by the terminal device according to the application attributes, for example, if the application attribute of the application a is unlocking, the important priority corresponding to the application attribute of the application a is first priority, the important priority corresponding to the application attribute of the application a is fingerprint payment, and the important priority corresponding to the application attribute of the application B is fingerprint payment; or, the importance priority corresponding to each application is determined by the terminal device according to the usage parameter of the application, for example, the usage parameter is the usage frequency, and a higher usage frequency indicates that the user information related to the application is more, and the corresponding importance priority is higher.
