As described in the background section, fingerprint recognition of existing electronic devices is difficult to balance between false and false rejects.
The inventor researches and finds that the phenomenon is more common when the finger environment of the user is dry. The inventor further studies and finds that the reason is that when the finger of the user is dry, the fingerprint identification component in the electronic equipment has poor identification precision on the fingerprint, in particular the ultrasonic fingerprint identification component or the light wave fingerprint identification component.
In view of this, an embodiment of the present application provides an electronic device, where the electronic device may be a notebook computer, a mobile phone, a door lock, or other devices. As shown in fig. 1, the electronic apparatus includes:
a fingerprint identification element 100 for detecting a fingerprint image located in a first area of a first surface of the electronic device;
the cooling element 200 is configured to cool a second area of the first surface of the electronic device, and reduce the temperature of the second area of the electronic device, so as to improve the recognition accuracy of the fingerprint recognition element when acquiring the fingerprint image of the first area.
Alternatively, on the basis of the above embodiments, in one embodiment of the present application, the fingerprint identification element is an ultrasonic fingerprint identification element, and in another embodiment of the present application, the fingerprint identification element is an optical fingerprint identification element, which is not limited in this application as long as the fingerprint identification accuracy of the fingerprint identification element in the case of wet fingerprint is higher than that in the case of dry fingerprint.
Therefore, the electronic equipment that this application embodiment provided not only includes the fingerprint identification component, still includes refrigeration component, thereby can utilize refrigeration component is right the second area on electronic equipment surface refrigerates, in order to reduce the temperature of electronic equipment surface second area, thereby reduce the temperature of first area, in order to utilize the temperature of first area is right moisture in the surrounding environment of first area condenses, improves the humidity of first area, and then improves the fingerprint identification component acquires the identification precision when the fingerprint image of the first area on electronic equipment surface, in order to reduce because the dry probability that leads to electronic equipment to carry out fingerprint identification of user's finger, is improving on the basis of electronic equipment recognition rate, reduce electronic equipment's false reject rate.
Specifically, on the basis of the above embodiments, in one embodiment of the present application, an orthographic projection of the cooling element on the first surface of the electronic device coincides with the second area, but the present application does not limit this, and in other embodiments of the present application, the orthographic projection of the cooling element on the first surface of the electronic device may be larger than the second area or smaller than the second area, as the case may be.
On the basis of any of the above embodiments, in an embodiment of the present application, an orthographic projection of the fingerprint identification element on the first surface of the electronic device completely covers the first area, so that a finger of a user is located at any position of the first area, and the fingerprint identification element can obtain a fingerprint image of the first area, but the present application is not limited thereto, as the case may be.
On the basis of any one of the above embodiments, in one embodiment of the present application, as shown in fig. 2, the refrigeration unit includes: a condenser, the condenser comprising: the power supply 201 is used for applying a voltage signal to the semiconductor material 204 between the first end face 202 and the second end face 203 and reducing the temperature of the first end face 202, wherein the first end face 202 is used for refrigerating a second area of a first surface of the electronic equipment so as to reduce the temperature of the second area, further reduce the temperature of the first area and improve the humidity of the first area.
Optionally, on the basis of the above embodiment, in an embodiment of the present application, the electronic device further includes a thermal conductive layer. Specifically, as shown in fig. 2, in an embodiment of the present application, the temperature conducting layer includes a first temperature conducting layer 301 located between the first end surface 202 and the first surface of the electronic device, so as to improve a heat conduction effect between the first end surface 202 of the condenser and the first surface of the electronic device, and improve a cooling effect of the cooling element 200 on the second area of the first surface of the electronic device.
On the basis of the foregoing embodiments, in an embodiment of the present application, an orthographic projection of the first temperature conductive layer on the first surface covers an orthographic projection of the fingerprint identification element and the refrigeration element on the first surface of the electronic device, so as to improve a heat conduction effect of the refrigeration element and the second region, a heat conduction effect of the refrigeration element and the first region, and a heat conduction effect of the second region and the first region by using the first temperature conductive layer, but the present application is not limited thereto as long as the first temperature conductive layer can improve a heat conduction effect of the refrigeration element and the second region.
Because one end face of two opposite end faces in the condenser cools and the other end face heats, in this application embodiment, the first end face of the condenser is used for cooling, and the second end face is used for heating, in order to reduce the influence of the heat of the second end face of the condenser on the electronic device, on the basis of any one of the above-mentioned embodiments, in another embodiment of this application, as shown in fig. 2, the temperature conducting layer further includes: and the second heat-conducting layer 302 is positioned on the surface of the second end surface 203, which is far away from the first end surface 202, so that the heat of the second end surface 203 of the condenser is quickly dissipated through the second heat-conducting layer 302.
Optionally, an orthographic projection of the second temperature conducting layer on the first surface of the electronic device completely covers an orthographic projection of the refrigeration element on the first surface of the electronic device, so that the second temperature conducting layer completely covers the second end face, and the heat dissipation effect of the refrigeration element is improved. Specifically, in an embodiment of the present application, an orthographic area of the second thermal conductive layer on the first surface of the electronic device is larger than an orthographic area of the cooling element on the first surface of the electronic device, but the present application does not limit this area, and the cooling element is optionally used.
On the basis of any of the above embodiments, in an embodiment of the present application, as shown in fig. 3, the second area B surrounds the first area a, and in the embodiment of the present application, the cooling element cools the second area to reduce the temperature of the second area, so that the temperature of the first area is reduced by heat conduction between the second area surrounding the first area and the first area, moisture in air at a position where the first area is located is condensed, and humidity of the first area is increased to improve the recognition accuracy when the fingerprint recognition element acquires the fingerprint image of the first area.
In the embodiment of the present application, the second area surrounds the first area, so that after the second area is cooled by the cooling element, heat can be conducted from the periphery of the first area to the first area, so as to improve the uniformity of the temperature distribution of the first area, and further improve the humidity balance of the first area, so as to balance the recognition accuracy of different areas of the fingerprint image of the first area on the basis of improving the recognition accuracy of the fingerprint image of the first area, and further improve the fingerprint recognition accuracy of the first area.
Optionally, on the basis of the above embodiment, in an embodiment of the present application, the first region is circular, and the second region is circular, but the present application does not limit this, and in other embodiments of the present application, the first region and the second region may also be in other shapes, as the case may be.
In another embodiment of the present application, the second region overlaps with the first region, so that the refrigeration element directly refrigerates the first region, the temperature of the first region is reduced, and the maximum humidification effect on the first region is achieved with the minimum power consumption.
In yet another embodiment of the present application, the second region and the first region partially overlap to reduce a heat conduction path between the second region and the first region while the second region is being refrigerated by the refrigeration component, and to improve a humidification effect of the first region upon the refrigeration of the second region by the refrigeration component.
In yet another embodiment of the present application, the second region and the first region may not overlap with each other, for example, the second region and the first region have a first distance therebetween, so that when the second region is cooled by the cooling element, the distance between the second region and the first region is used as a heat conduction path to transfer the temperature of the second region to the first region, thereby reducing the temperature of the first region and increasing the humidity of the first region.
It should be noted that, because the material of the first surface of the electronic device where the first area and the second area are located is different, the heat conduction effect before the second area and the first area is different, the refrigeration effect of the refrigeration element is different, and the heat conduction effect between the second area and the first area is also different, the application does not limit the distance between the first area and the second area, as long as the refrigeration element refrigerates the second area, and when the temperature of the second area is reduced, the heat of the first area can be transferred to the second area, so that the temperature of the first area is reduced, thereby increasing the humidity of the first area, further increasing the recognition accuracy when the fingerprint recognition element acquires the fingerprint image of the first area on the surface of the electronic device, so as to reduce the probability that the electronic device cannot perform fingerprint recognition due to the drying of the finger of the user, on the basis of improving the recognition rate of the electronic equipment, the false rejection rate of the electronic equipment is reduced.
It should be further noted that, in the above embodiment, when the humidity of the surface of the first area of the electronic device is increased, the humidity of the whole area of the first area may be increased, and the humidity of a partial area of the first area may also be increased.
In an embodiment of the present application, the cooling element is configured to cool the second area of the first surface of the electronic device when the electronic device satisfies the first condition, and not cool the second area when the electronic device does not satisfy the first condition, so as to reduce power consumption of the electronic device.
Because the electronic device does not need to perform fingerprint identification all the time in the operation process, if the refrigeration element is in the working state all the time, the power consumption of the electronic device is obviously increased more. Therefore, on the basis of any one of the above embodiments, in an embodiment of the present application, the first condition includes: the fingerprint identification element is in an opening state, so that whether the refrigeration element needs to refrigerate the second area or not is determined according to the working state of the fingerprint identification element. Specifically, in this embodiment of the application, if the fingerprint identification element is in an open state, the refrigeration element refrigerates the second area, so as to increase the humidity of the first area; if the fingerprint identification element is in a non-opening state (namely, a closing state), the refrigeration element does not refrigerate the second area, namely, does not humidify the first area.
On the basis of the above embodiment, in an embodiment of the present application, the refrigeration element may be activated before the fingerprint identification element is activated, so as to ensure that when the fingerprint identification element performs fingerprint image identification of the first area, the fingerprint image acquired by the fingerprint identification element is not defective due to late humidification of the first area by the refrigeration element. In another embodiment of the present application, the refrigeration element and the fingerprint identification element are turned on simultaneously, so as to ensure that the refrigeration element can shorten the operation time of the refrigeration element and reduce the power consumption of the electronic device on the basis of humidifying the first region when the fingerprint identification element operates, but the present application does not limit this.
Since the fingerprint identification element may only be unable to accurately identify the fingerprint image of the first area, and in most cases, the fingerprint image may be accurately identified, based on any of the above embodiments, in an embodiment of the present application, the first condition includes: the fingerprint identification component detects the fingerprint image on the first surface of the electronic equipment can not extract the characteristic point (namely, the fingerprint identification component can not accurately identify the fingerprint image in the first area), so that when the fingerprint identification component can not accurately identify the fingerprint image in the first area, the second refrigeration component is utilized to refrigerate the second area, the humidity of the first area is improved, when the fingerprint image on the first surface of the electronic equipment can extract the characteristic point (namely, the fingerprint identification component can accurately identify the fingerprint image in the first area), the refrigeration component is not utilized to refrigerate the second area, the power consumption of the refrigeration component is reduced, and the power consumption of the electronic equipment is reduced.
Because the finger of the user is not always in a dry state when the fingerprint identification element in the electronic equipment performs fingerprint identification, if the finger of the user is in a non-dry state, the first area is still humidified, so that the precision during fingerprint identification is improved, the power consumption of the electronic equipment is wasted, and adverse effects can be possibly played.
Therefore, on the basis of any one of the above embodiments, in an embodiment of the present application, the first condition is that the humidity in the environment where the electronic device is located is smaller than a first value, so as to determine whether the fingerprint identification environment of the first area is dry or not through the humidity of the environment where the electronic device is located, so that when the identification environment when performing fingerprint identification on the fingerprint of a user is dry, the humidity of the first area is increased, the fingerprint identification accuracy of the first area is increased, and when the identification environment when performing fingerprint identification on the fingerprint of the user is not dry, the second area is not cooled, so as to reduce the power consumption of the electronic device.
Optionally, on the basis of the above embodiment, in an embodiment of the present application, the first value may be 10%, but the present application does not limit this, and in other embodiments of the present application, the first humidity may also be other values, as the case may be.
Since the humidity of the first area on the surface of the electronic device is greatly affected by the humidity of the environment where the electronic device is located, on the basis of the above embodiment, in an embodiment of the present application, the electronic device further includes: the humidity sensor is used for detecting the humidity of the environment where the electronic equipment is located, the humidity of the environment where the electronic equipment is located is used for determining whether the humidity of the first surface of the electronic equipment is smaller than the first numerical value, and therefore whether the humidity of the first surface of the electronic equipment is smaller than the first numerical value or not is automatically judged through the humidity of the environment where the electronic equipment is located, which is detected by the humidity sensor.
Since the humidity of the first surface of the electronic device may be different at different temperatures and under the same humidity, on the basis of the above embodiments, in an embodiment of the present application, the electronic device further includes: the temperature sensor is used for detecting the temperature of the environment where the electronic equipment is located, so that whether the humidity of the first surface of the electronic equipment is smaller than a first numerical value or not is comprehensively determined according to the humidity of the environment where the electronic equipment is located and the temperature of the environment where the electronic equipment is located, and therefore the accuracy of automatically judging whether the humidity of the first surface of the electronic equipment is smaller than the first numerical value or not is improved.
Since the humidity in the environment of different areas is different at the same humidity and the same temperature, for example, the humidity of the first surface of the electronic device is different due to different moisture contents in the air in the environment of the same humidity and the same temperature in south china and north east china, on the basis of the above embodiments, in an embodiment of the present application, the electronic device further includes: the position positioning element is used for acquiring the geographical position of the electronic equipment, and comprehensively judging whether the humidity of the first surface of the electronic equipment is smaller than a first numerical value or not through the humidity of the environment where the electronic equipment is located, the temperature of the environment where the electronic equipment is located and the geographical position where the electronic equipment is located, so that the accuracy of automatically judging whether the humidity of the first surface of the electronic equipment is smaller than the first numerical value or not is further improved.
On the basis of any of the above embodiments, in an embodiment of the present application, as shown in fig. 4, the electronic device further includes: the control element 400 is configured to control the refrigeration element 200 to start working when the electronic device meets a first condition, so that the refrigeration element 200 is automatically started to refrigerate the second area to improve the humidity of the first area when the electronic device meets the first condition, but this application is not limited to this, and in other embodiments of the application, the control element 400 may be manually started to refrigerate the second area to improve the humidity of the first area when the electronic device meets the first condition, which is specifically determined by the situation.
It should be noted that, since the humidity of the first area on the first surface of the electronic device meets a certain requirement, the accurate identification of the fingerprint image of the first area by the fingerprint identification element can be ensured, and on this basis, if the humidity of the first area on the first surface of the electronic device is further increased, not only the accuracy of identifying the fingerprint image of the first area by the fingerprint identification element is not significantly improved, but also water drops are formed, which affects the user experience and causes more resource waste.
Therefore, on the basis of any one of the above embodiments, in an embodiment of the present application, the control element is further configured to control a refrigeration parameter of the refrigeration element for the second area, so as to control the refrigeration element to stop refrigerating the second area when the humidity of the first area meets a preset humidity requirement, so that on the basis of improving the recognition accuracy of the fingerprint image of the first area by the fingerprint recognition element, the first area is not excessively humidified, which affects user experience and causes resource waste.
It should be noted that, since the influence on the refrigeration effect of the refrigeration element includes not only the refrigeration duration of the refrigeration element but also the refrigeration capacity of the refrigeration element per unit time, on the basis of the above embodiments, in an embodiment of the present application, the control element controls the refrigeration effect of the refrigeration element on the second area by controlling at least one of the refrigeration duration of the refrigeration element and the refrigeration capacity per unit time.
Specifically, on the basis of the above embodiment, in an embodiment of the present application, the control element controls the duration of the cooling element by controlling the duration of the voltage applied to the semiconductor material by the power supply in the cooling element, so as to control the cooling effect of the cooling element on the second area.
In another embodiment of the present application, the control element controls the refrigerating capacity of the refrigerating element per unit time by controlling the value of the voltage applied to the semiconductor material by the power supply in the refrigerating element, thereby controlling the refrigerating effect of the refrigerating element on the second area.
On the basis of any of the foregoing embodiments, in an embodiment of the present application, as shown in fig. 5, the control element 400 is further configured to determine, based on at least one of the humidity sensor 500, the temperature sensor 600, and the geographic position locating element 700, the humidity of the first surface of the electronic device, and determine, based on the humidity of the first surface of the electronic device, the cooling capacity of the cooling element 200 for the second area, so as to determine, based on the cooling capacity of the cooling element 200 for the second area, a cooling parameter of the cooling element, and control the cooling effect of the cooling element 200 for the second area, and further reduce the power consumption of the cooling element 200 on the basis of improving the fingerprint identification accuracy of the first area.
It should be noted that, in the above embodiment, when the control element determines the cooling capacity of the cooling element for the second area based on the humidity of the first surface of the electronic device, the control element determines the cooling capacity of the cooling element for the second area by querying the correspondence between the temperature of the first surface of the electronic device and the cooling capacity of the cooling element for the second area based on the humidity of the first surface of the electronic device.
On the basis of the above embodiment, in an embodiment of the present application, the electronic device includes a storage element, and a correspondence between a first surface temperature of the electronic device and a cooling capacity of the cooling element for the second area is stored in the storage element. In this embodiment of the application, the control element determines the cooling capacity of the cooling element for the second area based on the humidity of the first surface of the electronic device by reading the correspondence between the temperature of the first surface of the electronic device and the cooling capacity of the cooling element for the second area, which is stored in the storage element. Optionally, in this embodiment of the application, a correspondence between the temperature of the first surface of the electronic device and the cooling capacity of the cooling element for the second area may be obtained through a preliminary experiment.
In another embodiment of the present application, as shown in fig. 6, the correspondence between the first surface temperature of the electronic device and the cooling capacity of the cooling element 200 for the second area is stored in a network information center 800 (such as a cloud end), and in this embodiment of the present application, the control element 400 determines the cooling capacity of the cooling element 200 for the second area based on the humidity of the first surface of the electronic device by obtaining the correspondence between the first surface temperature of the electronic device and the cooling capacity of the cooling element 200 for the second area, which are stored in the network information center 800. Optionally, in this embodiment of the present application, the correspondence between the temperature of the first surface of the electronic device and the cooling capacity of the cooling element for the second area is obtained through big data.
In another embodiment of the present application, when the control element is configured to determine the cooling capacity of the cooling element for the second area based on the humidity of the first surface of the electronic device, information such as the temperature, the humidity, and the geographic location element of the location of the electronic device may be input into an intelligent model, and the cooling capacity of the cooling element for the first surface of the electronic device is obtained through the intelligent model, which is not limited in this application, as the case may be. The intelligent model is obtained through artificial intelligence training, so that when at least one of the humidity, the temperature and the geographic position of the electronic device is input into the intelligent model, the intelligent model can output the refrigerating capacity of the corresponding refrigerating element to the second area.
Specifically, on the basis of the foregoing embodiment, in an embodiment of the present application, the artificial intelligence training process of the intelligent model includes: and inputting a plurality of groups of training data into the intelligent model, wherein each group of training data comprises at least one of the temperature, the humidity and the geographic position of the position where the electronic equipment is located, and calibrating the refrigerating capacity of the second area by using the refrigerating element corresponding to each group of training data. The more data used for training is in the process of obtaining the intelligent model through training, and the higher the precision of the intelligent model is in subsequent use.
It should be noted that, if the humidity on the first surface of the electronic device is not less than the first value, the finger of the user may be too dry, which may also result in that the fingerprint identification element cannot quickly and effectively acquire the fingerprint image of the first area, so on the basis of any of the above embodiments, in an embodiment of the present application, the control element is further configured to obtain the dry state of the finger of the user based on the climate information of the location where the electronic device is located, so as to determine the cooling capacity of the cooling element for the second area by comprehensively considering the humidity on the first surface of the electronic device and the dry state of the finger of the user, further improve the accuracy of acquiring the fingerprint image of the first area by the fingerprint identification element, and reduce the power consumption of the electronic device.
