[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Fingerprint unlocking is a biometric technology, and users can turn on the device to be used through the entered fingerprint information.

[0032] In the related art, a fingerprint verification module is added to a laptop. A user can input a fingerprint by touching the fingerprint collection area of the fingerprint verification module. The fingerprint verification module compares the fingerprint input by the user with the pre-stored fingerprint. After the comparison is consistent, the verification is passed, and the laptop can be unlocked.

[0033] However, the above solution cannot provide the most intuitive feedback on whether the fingerprint verification is successful during the fingerprint verification process. The user needs to observe the changes on the laptop screen to assist in judging whether the verification is successful, which may cause the user to repeatedly verify due to delays, etc., reducing the verification efficiency and user experience.

[0034] Therefore, the embodiments of the present invention provide a fingerprint verification device, which can timely remind the user of the fingerprint verification result by setting a fingerprint LED lamp, thereby improving the verification efficiency.

[0035] Figure 1 It is a schematic structural diagram of a fingerprint verification device according to an embodiment of the present invention. As Figure 1 shown, in this fingerprint verification device, it includes an MCU, a fingerprint module, a first fingerprint LED lamp, and a second fingerprint LED lamp. The MCU includes a fingerprint receiving port, a first level output port, and a second level output port. The fingerprint module is used to collect fingerprints. The fingerprint module is electrically connected to the MCU through this fingerprint receiving port. The first fingerprint LED lamp is arranged at a first position of the fingerprint module, and the first level output port is grounded through the first fingerprint LED lamp. The second fingerprint LED lamp is arranged at a second position of the fingerprint module, and the second level output port is grounded through the second fingerprint LED lamp.

[0036] Figure 1 The working principle of the shown fingerprint verification device is as follows:

[0037] The MCU (Microcontroller Unit) is a micro control unit. In order to clearly and timely feedback the verification result during the fingerprint verification of the laptop, the MCU is set in the laptop. The MCU can be additionally selected and installed in the laptop, or the existing MCU in the laptop can be selected as the MCU of the present invention.

[0038] The fingerprint module includes a position for collecting fingerprints and can be implemented by a module with fingerprint collection function in the related art. When the user performs fingerprint verification, the finger is pressed on the position of the fingerprint module for collecting fingerprints to collect fingerprints.

[0039] After the fingerprint module collects the user's fingerprint, the collected fingerprint is sent to the MCU through the fingerprint receiving port of the MCU. The MCU compares the received fingerprint with the pre-stored fingerprint. If the comparison is consistent, the fingerprint verification is passed, and the MCU outputs a high level to the first level output port. The first fingerprint LED light receives the high level through the first level output port, and the first fingerprint LED light lights up to remind the user that the verification is passed; if the comparison is inconsistent, the fingerprint verification fails, and the MCU outputs a high level to the second level output port. The second fingerprint LED light receives the high level through the second level output port, and the second fingerprint LED light lights up to remind the user that the verification fails.

[0040] Through the lighting conditions of the first fingerprint LED light and the second fingerprint LED light, the user can clearly and timely obtain the result of the fingerprint verification, without having to view it through the screen of the laptop, nor will there be a situation of repeated verification due to delays or poor contact, etc., improving the efficiency of fingerprint verification and ensuring the user experience.

[0041] Among them, the first fingerprint LED light is set at the first position of the fingerprint module, and the second fingerprint LED light is set at the second position of the fingerprint module. The first position and the second position can be set side by side, or can be set separately. For example, the first position and the second position are set side by side in the upper left corner of the fingerprint module, or the first position is set on the left side of the fingerprint module, and the second position is set on the right side of the fingerprint module. The first fingerprint LED light and the second fingerprint LED light can be distinguished by the set positions. For example, the first fingerprint LED light is set on the left, and the second fingerprint LED light is set on the right. Corresponding identifiers can also be set to distinguish the first fingerprint LED light and the second fingerprint LED light. For example, the number "1" is marked to represent the first fingerprint LED light, and the number "2" is marked to represent the second fingerprint LED light.

[0042] In an alternative embodiment, the first fingerprint LED light lights up green when the first level output port outputs a high level. That is to say, the light of the first fingerprint LED light is green. By setting the first fingerprint LED light with a relatively bright color, the situation of successful fingerprint verification can be better and timely feedback to the user.

[0043] In an alternative embodiment, the first fingerprint LED light goes out when the first level output port outputs a low level. The MCU controls the lighting and extinguishing of the first fingerprint LED light by outputting high and low levels to the first level output port.

[0044] In an alternative embodiment, the second fingerprint LED light lights up red when the second level output port outputs a high level. That is to say, the light of the second fingerprint LED light is red. By setting the second fingerprint LED light with a relatively bright color, the situation of failed fingerprint verification can be better and timely feedback to the user.

[0045] In an alternative embodiment, the second fingerprint LED light is turned off when a low level is output at the second level output port. The MCU controls the turning on and off of the second fingerprint LED light by outputting high and low levels to the second level output port.

[0046] Furthermore, by combining the above solutions, the fingerprint verification result can be clearly distinguished by the first fingerprint LED light with green light and the second fingerprint LED light with red light, enabling the fingerprint verification result to be more clearly and timely feedback to the user.

[0047] Optionally, the device further includes a first resistor and a second resistor. The first level output port is grounded through the first resistor and the first fingerprint LED light in sequence, and the second level output port is grounded through the second resistor and the second fingerprint LED light in sequence. The first resistor and the second resistor play a protective role.

[0048] In an alternative embodiment, the MCU further includes a fingerprint information storage port, and the MCU is electrically connected to a fingerprint information storage device through this fingerprint information storage port. The fingerprint information storage device pre-stores the fingerprint information input by the user. During fingerprint verification, the MCU can read the pre-stored fingerprint in the fingerprint information storage device through the fingerprint information storage port to compare the pre-stored fingerprint information with the collected user fingerprint for fingerprint verification. The fingerprint information storage device can be installed separately or directly use a memory card in a laptop computer as the fingerprint information storage device.

[0049] In an alternative embodiment, the device further includes a display screen, and the display screen is turned on after a high level is output at the first level output port. The display screen can be the display screen of a laptop computer. By setting the display screen to turn on after a high level is output at the first level output port, the display screen can be turned on after the fingerprint verification is passed, avoiding the inconvenience caused by the lack of intuitiveness in viewing the fingerprint verification result through the display screen, as well as the continuous opening and repeated switching of the display screen interface due to delay and poor contact, saving energy consumption.

[0050] In an alternative embodiment, after the display screen is turned on, a low level is output at the first level output port. After the fingerprint verification is passed and the display screen is turned on, the user no longer needs to confirm the fingerprint verification result. At this time, the MCU detects the change of the display screen and outputs a low level to the first level output port to turn off the first fingerprint LED light, achieving the effect of saving energy consumption.

[0051] In an alternative embodiment, the MCU further includes an interrupt pin and a first clock pin. The interrupt pin receives an interrupt signal. The first clock pin receives a clock signal. By inputting the interrupt signal, the MCU can be switched between different tasks. By inputting the clock signal, the timing and synchronization mechanism between the MCU and other components can be ensured, ensuring that all components can work in a coordinated manner.

[0052] In an alternative embodiment, the fingerprint module further includes a second clock pin, and the second clock pin receives a clock signal. By inputting the clock signal, the timing and synchronization mechanism between the fingerprint module and other components can be ensured, ensuring that all components can work in a coordinated manner.

[0053] It should be noted that the program for the MCU to perform fingerprint verification in the present utility model is implemented by a program with fingerprint verification function in related technologies, and the program for the MCU to perform fingerprint verification has nothing to do with the innovative points of the present utility model.

[0054] In summary, the fingerprint verification device provided by the present utility model collects the user's fingerprint through the fingerprint module, sends it to the MCU through the fingerprint receiving port, the MCU verifies the collected user fingerprint, and outputs high and low levels through the first level output port and the second level output port, so that the first fingerprint LED light and the second fingerprint LED light are turned on or off, achieving the effect of clearly and timely feedback the fingerprint verification result to the user. The user does not need to assist in judging whether the verification is successful by observing the change of the notebook computer screen, avoiding repeated verification by the user due to delays, poor contacts, etc., thereby improving the fingerprint verification efficiency and user experience.
