3 to 5, the present invention provides a fingerprint module structure including: a casing 100 and a fingerprint identification module 210 disposed in the casing 100; wherein, the casing 100 is made of a material with adjustable transparency, Alternatively, an area corresponding to the fingerprint recognition module 210 on the casing 100 is provided with a sensing portion 121 , and the sensing portion 121 is made of an adjustable transparency material or a light-transmitting material.

In the above technical solution of the present invention, since the fingerprint module structure includes the casing 100 and the fingerprint identification module 210 disposed in the casing 100, the casing 100 is made of a material with adjustable transparency, or the casing 100 is The area corresponding to the fingerprint identification module 210 is provided with a sensing portion 121 , and the sensing portion 121 is made of an adjustable transparency material or a light-transmitting material. When the sensing portion 121 is made of light-transmitting material, the light-transmitting material enables the fingerprint recognition module 210 to perform fingerprint recognition across the casing 100 , and the user places his finger on the casing 100 in an area corresponding to the fingerprint recognition module 210 . The fingerprint recognition function can be realized. When the entire casing 100 is made of a material with adjustable transparency or the sensing part 121 is made of a material with adjustable transparency, the casing 100 or the sensing part 121 can be controlled to change from an opaque state to a transparent state when there is a need for fingerprint identification. The fingerprint recognition function can also be realized by placing the user's finger on the area of the casing 100 corresponding to the fingerprint recognition module 210 . The solution of the present invention makes the casing 100 not need to be opened due to fingerprint recognition, and can be applied to a non-porous body without affecting the waterproof performance and dust-proof performance of the smart terminal. At the same time, the non-porous back shell makes the smart terminal More beautiful in appearance.

As a preferred embodiment of the present invention, the tunable transparency material may be atomized glass. Atomized glass is also known as dimming glass, electronically controlled glass, and intelligent dimming and color-changing glass. The atomized glass can be controlled to change between transparent and opaque through voltage. When there is no need for fingerprint identification, the control housing 100 or the sensing portion 121 is transformed from an opaque state to a transparent state, so that the fingerprint module can identify the user's finger. When there is no need for fingerprint identification, the entire casing 100 is in an opaque state to ensure the aesthetics of the body.

As another preferred embodiment of the present invention, an area corresponding to the fingerprint recognition module 210 on the casing 100 is provided with a sensing portion 121, and the sensing portion 121 is made of a light-transmitting material. The light-transmitting material can be light-transmitting glass, and the light-transmitting glass is a processed glass material, so that the light transmittance can meet the identification requirements of the fingerprint identification module 210. Further, the housing 100 includes a front case 110 and a back case 120 matched with the front case 110, and the photosensitive head of the fingerprint identification module 210 faces the back case 120. In this embodiment, the fingerprint identification module 210 is identified by touching the back shell 120. Since the display screen 500 is disposed in the area where the front case 110 is located, the display screen 500 occupies almost all the area. The fingerprint identification module 210 is arranged close to the back case 120, and the photosensitive head of the fingerprint identification module 210 is directed toward the back case 120, so that the space on the mobile phone can be better utilized. Wherein, the induction part 121 may be integrated with the casing 100, or may be independent. Further, the back case 120 is a glass case, and the glass case includes a base portion and a sensing portion 121 that are integrally provided, and the light transmittance of the sensing portion 121 is greater than that of the base portion. In this embodiment, the entire back shell 120 is set as a glass shell, and the glass shell is composed of a base portion and a sensing portion 121, and the base portion and the sensing portion 121 are integrally formed. Wherein, the sensing part 121 is set corresponding to the area of the fingerprint identification module 210, all other areas are set as the base, and the light transmittance of the sensing part 121 is greater than that of the base. In actual processing, the light transmittance of the sensing portion 121 is customized according to the identification requirements, so as to meet the identification accuracy of the fingerprint identification module 210. However, the light transmittance of the base is relatively poor, and the user cannot see the internal structure of the smart terminal through the base.

As an optional embodiment of the present invention, the sensing portion 121 is circular, and the sensing portion 121 in the circular area corresponds to the fingerprint recognition module 210 . The surface roughness of the sensing portion 121 is different from that of other parts on the housing 100 . Specifically, the surface of the sensing portion 121 can be made smooth or rougher than other parts on the housing 100 , so that the user can know whether the sensor is touched by the touch of the finger. The touch sensing portion 121 is especially suitable for models in which the fingerprint identification module 210 is arranged on the back of the mobile phone.

Wherein, the fingerprint identification module 210 can be an optical fingerprint identification module or a capacitive fingerprint identification module. The optical fingerprint recognition module mainly obtains the user's fingerprint through the optical fingerprint sensor. The optical fingerprint sensor uses the principle of light refraction and reflection to place the fingerprint on the lens. The angle of refraction of the light emitted by the prism on the uneven lines of the fingerprint on the surface of the finger and the light and shade of the reflected light will be different. This solution can also be applied to the capacitive fingerprint identification module, by adjusting the thickness of the sensing portion 121 to meet the identification requirements of the capacitive fingerprint identification module.

As a further embodiment of the present invention, foam is arranged between the fingerprint identification module 210 and the housing 100. Foam is a material that has been foamed by plastic particles, referred to as foam. Foam has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, convenient use, free bending, ultra-thin volume, and reliable performance. In this embodiment, the foam can be in contact with the fingerprint identification module 210 on a low surface to achieve rapid pressure-sensitive fixation, and play a sealing role, so that the fingerprint identification module 210 can be firmly attached to the housing 100 to avoid The fingerprint recognition module 210 shakes.

In addition, the present invention also provides a fingerprint module identification method, which is applied to the fingerprint module structure as described above, wherein the casing 100 is made of a material with adjustable transparency, or the casing 100 corresponds to the fingerprint identification module 210 The area of is provided with an induction part 121, and the induction part 121 is made of a material with adjustable transparency;

The fingerprint module identification method includes:

S10, when an unlocking instruction is received, control the casing or the sensing portion to transition from an opaque state to a transparent state.

The unlock command can be triggered by the power button. The user sends the unlock command by short pressing the power button. After receiving the unlock command, the main board of the terminal controls the voltage of the adjustable transparency material to make the casing or the sensing part change from an opaque state to a transparent state.

In this embodiment, the entire casing of the smartphone is in an opaque state to ensure the aesthetics of the body. When fingerprint identification is required, the user can trigger the unlocking instruction through the power-on button, and control the housing or the sensing part to change from an opaque state to a transparent state. In this way, the fingerprint module can be put into a dormant state to save the state when it is not needed, and it can also increase the sense of technology and intelligence of the terminal.

Preferably, the fingerprint module identification method further includes:

receiving the shaking amplitude obtained by the sensor, and judging whether the shaking amplitude exceeds a preset threshold;

When the judgment result is that it exceeds the preset threshold, the casing or the sensing part is controlled to be transformed from an opaque state to a transparent state.

In this implementation manner, the shaking amplitude of the intelligent terminal is also monitored in real time through the sensor. The built-in sensor of the terminal will detect the amplitude and frequency of the terminal shaking in real time, as the basis for judging whether the shaking operation is an effective shaking operation, where the shaking amplitude can be the shaking amplitude in at least one of the three-dimensional X direction, Y direction or Z direction. . In addition, the basis for judging whether the shaking operation is an effective shaking operation may also be the acceleration value of the mobile phone. According to the moving state of the smart terminal during use, such as when the screen is off, it is shaken by a relatively large amount, and the shaking amplitude exceeds the preset threshold, it is determined that the user needs to use the fingerprint to unlock, and the casing or the sensing part is controlled to be opaque. The state transitions to the transparent state.

As a preferred embodiment of the present invention, the fingerprint module structure further includes an LED light 211 disposed in the housing 100 , and the LED light 211 is disposed close to the fingerprint identification module 210 . LED light-emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. Compared with the luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, which successfully integrate computer technology, network communication technology, image processing technology and embedded control technology. In the present embodiment, the LED light 211 provided near the sensing portion 121 is used to fill light on the fingerprint identification module 210, and at the same time can prompt the user of the location of the fingerprint identification module 210, so that the user can quickly find the area touched by the finger. In addition, LED lights 211 can make cool lighting effects, increase product differentiation and aesthetics, and enhance the overall sense of technology.

After the step of controlling the transition of the housing or the sensing portion from an opaque state to a transparent state, it further includes:

Turn on the fingerprint identification module and the LED light;

Within a preset time period after turning on the fingerprint recognition module and the LED light, if the unlocking is completed or no operation command is received, the fingerprint recognition module and the LED light are turned off, and the casing or the sensor is controlled. The part is transformed from a transparent state to an opaque state.

In this embodiment, the fingerprint module is generally in a dormant state to save power. When it is necessary to unlock the fingerprint, control the fingerprint identification module and the LED light to turn on. At this time, the unlocking operation can be completed only by bringing the finger that has entered the fingerprint close to the identification area of the fingerprint identification module. When the fingerprint unlocking operation is successfully completed or no operation is performed within the preset time period, the fingerprint recognition module and the LED light will automatically turn off and enter the sleep state to save power. The LED light is used to fill in the light for the fingerprint identification module, and at the same time, it can remind the user of the location of the fingerprint identification module to enhance the aesthetics. When the fingerprint recognition module and the LED light are turned on, the user can perform the fingerprint unlocking operation within a preset time period. If the user successfully unlocks or does not perform any operation within the preset time period, the fingerprint recognition module and LED light will be automatically turned off and enter a sleep state to save power. And control the housing or the induction part to change from the transparent state to the opaque state.
