Referring to fig. 2, fig. 2 is a cross-sectional view of an ultrasonic sensor 20 in the terminal 10 according to the embodiment of the present disclosure.
The ultrasonic sensor 20 includes a control circuit layer 21, a negative electrode layer 22, a piezoelectric material layer 23, a positive electrode layer 24, and a fixed layer 25. The control circuit layer 21, the negative electrode layer 22, the piezoelectric material layer 23, the positive electrode layer 24, and the fixing layer 25 are sequentially stacked.
The control circuit layer 21 is used for controlling the ultrasonic sensor 20, for example, controlling the ultrasonic sensor 20 to emit an ultrasonic signal and controlling the ultrasonic sensor 20 to receive a reflection signal of an obstacle. The control circuit layer 21 may include a plurality of Thin Film Transistors (TFTs) and a connection circuit between the TFTs.
The negative electrode layer 22 and the positive electrode layer 24 constitute two electrodes of the piezoelectric material layer 23, so that a voltage can be applied to the piezoelectric material layer 23 through the negative electrode layer 22 and the positive electrode layer 24. Wherein the positive electrode layer 24 may be a silver paste layer.
The piezoelectric material layer 23 is used to generate an ultrasonic signal and receive a reflected signal of an obstacle. Wherein the piezoelectric material layer 23 comprises a piezoelectric material, which may be, for example, a piezoelectric ceramic.
When an ac voltage is applied to the piezoelectric material layer 23, for example, a high-frequency oscillation signal is applied to the piezoelectric material layer 23, the piezoelectric material layer 23 generates an ultrasonic signal and emits the ultrasonic signal to the outside. When no voltage is applied to the piezoelectric material layer 23, the piezoelectric material layer 23 may receive an ultrasonic signal reflected by an external obstacle, and convert the received reflected signal into a corresponding electrical signal, thereby implementing identification of the reflected signal.
The fixing layer 25 is used to fix the ultrasonic sensor 20, so as to implement the installation of the ultrasonic sensor 20 in the terminal 10. For example, the fixing layer 25 may be a colloidal layer.
It will be appreciated that the ultrasonic sensor may also be integrated into the display 11 of the terminal 10 in order to reduce the occupation of the internal space of the terminal by the ultrasonic sensor or to enhance the intensity of the ultrasonic signal emitted to the outside by the ultrasonic sensor.
Referring to fig. 3, fig. 3 is a cross-sectional view of the display 11 in the terminal 10 shown in fig. 1, taken along the direction Q-Q. Wherein the ultrasonic sensor is integrated in the display screen 11.
The display panel 11 includes an upper glass substrate 11a, an ultrasonic sensor control circuit layer 11b, a negative electrode layer 11c, a light emitting layer 11d, a piezoelectric material layer 11e, a positive electrode layer 11f, a fixing layer 11g, and a lower glass substrate 11h, which are laminated in this order. The upper glass substrate 11a, the light emitting layer 11d and the lower glass substrate 11h are used for realizing the display function of the display screen; the ultrasonic sensor control circuit layer 11b, the negative electrode layer 11c, the piezoelectric material layer 11e, the positive electrode layer 11f and the fixing layer 11g are used for realizing the functions of transmitting an ultrasonic signal and receiving a reflected signal of the ultrasonic sensor, so that the integration of the ultrasonic sensor in a display screen is realized.
The upper glass substrate 11a and the lower glass substrate 11h serve as glass substrates on both sides of the display panel 11 to provide a supporting function for other layered structures of the display panel 11, or it is understood that other layered structures of the display panel 11 may be disposed on the upper glass substrate 11a and the lower glass substrate 11 h. The light emitting layer 11d is used to emit light or transmit light, thereby allowing the display panel 11 to display information. For example, when the Display panel 11 is a Liquid Crystal Display (LCD), the light-emitting layer 11d includes a Liquid Crystal layer; when the display panel 11 is an Organic Light-Emitting Diode (OLED) display panel, the Light-Emitting layer 11d includes an Organic Light-Emitting layer.
The ultrasonic sensor control circuit layer 11b is used to control the ultrasonic sensor integrated in the display screen 11, for example, to control the ultrasonic sensor to emit an ultrasonic signal and to control the ultrasonic sensor to receive a reflected signal of an obstacle. It is understood that the ultrasonic sensor control circuit layer 11b may be used to control the piezoelectric material layer 11e to generate an ultrasonic signal or to receive a reflected signal of an obstacle.
The negative electrode layer 11c and the positive electrode layer 11f constitute two electrodes of the piezoelectric material layer 11e, and thereby apply a voltage to the piezoelectric material layer 11 e. Wherein the positive electrode layer 11f may be a silver paste layer.
The piezoelectric material layer 11e is used for generating an ultrasonic signal and receiving a reflected signal of an obstacle. Wherein the piezoelectric material layer 11e includes a piezoelectric material, which may be, for example, a piezoelectric ceramic.
The fixing layer 11g is used to fix the ultrasonic sensor. For example, the fixing layer 11g is used to fix the positive electrode layer 11f on the lower glass substrate 11 h.
Here, the ultrasonic sensor control circuit layer 11b, the negative electrode layer 11c, the piezoelectric material layer 11e, the positive electrode layer 11f, and the fixing layer 11g may also refer to the above description of the control circuit layer 21, the negative electrode layer 22, the piezoelectric material layer 23, the positive electrode layer 24, and the fixing layer 25.
It is understood that the display panel 11 may further include one or more polarizers, one or more color filters, one or more panel driving electrodes, one or more panel control circuits, and the like. The polaroid, the color filter, the display screen driving electrode and the display screen control circuit are also used for realizing the display function of the display screen. For example, the polarizer is used for polarizing light emitted by the display screen, the color filter is used for color filtering light emitted by the display screen, the display screen driving electrode is used for inputting driving signals such as data signals and scanning signals to the display screen, and the display screen control circuit is used for controlling the display screen. Wherein the display screen control circuit may include a plurality of TFTs and a connection circuit between the plurality of TFTs.
The control circuit layer 11b of the ultrasonic sensor and the control circuit of the display screen in the display screen 11 may also be replaced by a control circuit, that is, the control circuit of the ultrasonic sensor and the control circuit of the display screen share a control circuit. Therefore, the situation that a plurality of control circuits are arranged inside the display screen can be avoided, and the layout space utilization rate inside the display screen can be improved.
For example, both the control of the ultrasonic sensor and the control of the display screen can be realized by the ultrasonic sensor control circuit layer 11 b. The ultrasonic sensor control circuit layer 11b may implement common control over the ultrasonic sensor and the display screen by partitioning, that is, a part of circuits in the ultrasonic sensor control circuit layer 11b is used to implement control over the ultrasonic sensor, and another part of circuits is used to implement control over the display screen.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a principle of fingerprint recognition by an ultrasonic sensor according to an embodiment of the present application.
Wherein, when the finger of the user contacts or presses on the surface of the terminal (such as the surface of a display screen), the terminal controls the ultrasonic sensor to emit the ultrasonic signal towards the direction of the finger. When the ultrasonic wave signal contacts with a finger, a reflection signal is generated. The reflected signal is reflected to the ultrasonic sensor and received by the ultrasonic sensor. And then, the ultrasonic sensor converts the received reflection signal into a corresponding electric signal, and the fingerprint image of the finger of the user can be obtained.
It will be appreciated that the finger surface presents a fingerprint pattern formed by areas of relief. Therefore, when the ultrasonic signal is reflected by different areas of the fingerprint pattern to form a reflected signal, the intensity of the reflected signal is different, and the intensity of the reflected signal received by the ultrasonic sensor at different parts of the finger is also different. Therefore, the ultrasonic sensor can acquire the concave-convex degrees of different parts of the finger according to the intensity of the reflected signals of the different parts of the finger, and a three-dimensional fingerprint image of the finger of the user can be formed.
For example, the deepest depressions in the fingerprint pattern may be referred to as fingerprint valleys, and the highest projections in the fingerprint pattern may be referred to as fingerprint ridges. When the user's finger reflects the ultrasonic signal to generate a reflection signal, the intensity of the reflection signal generated by the fingerprint valley is the weakest, and the intensity of the reflection signal generated by the fingerprint ridge is the strongest. The ultrasonic sensor can identify fingerprint valleys and fingerprint ridges on the finger according to the received intensity of the reflected signals generated by different parts of the finger.
Referring to fig. 5, 6, and 7, fig. 5 is a schematic view of a scene where an ultrasonic sensor performs fingerprint identification according to an embodiment of the present disclosure, fig. 6 is another schematic view of an ultrasonic sensor performing fingerprint identification according to an embodiment of the present disclosure, and fig. 7 is a schematic view of a change of a reflection signal received by the ultrasonic sensor in a terminal according to an embodiment of the present disclosure.
It will be appreciated that the user's finger presents an epidermis layer and a dermis layer with a thickness therebetween, that is, the thickness of the epidermis layer. Although the thickness of the epidermis layer of the finger is small, for example, 0.5mm (milliseconds), it is sufficient to influence the reflection signal generated by the reflection of the ultrasonic signal by the finger.
After the ultrasonic sensor emits the ultrasonic signal, the ultrasonic signal contacts the epidermis layer of the finger of the user to generate a reflection signal, which is the epidermis layer reflection signal or is called as a first reflection signal. Meanwhile, when the ultrasonic signal is reflected by the epidermis layer of the finger, the ultrasonic signal also penetrates the epidermis layer of the finger and contacts the dermis layer of the finger, and is reflected by the dermis layer to generate a reflection signal, namely a dermis layer reflection signal, or a second reflection signal. The first reflected signal and the second reflected signal are both reflected back to the ultrasonic sensor and are received by the ultrasonic sensor.
On the other hand, since it takes a certain period of time for the ultrasound signal to transmit through the epidermis layer of the finger to the epidermis layer, and it also takes a certain period of time for the second reflection signal generated by the reflection of the dermis layer to transmit from the dermis layer to the epidermis layer, the time when the ultrasound sensor receives the first reflection signal is earlier than the time when the second reflection signal is received. That is, the time t when the ultrasonic sensor receives the first reflected signal1And the time t of receiving the second reflected signal2With a time interval T in between. The time period T is 2 times the time period it takes for the ultrasonic signal to be transmitted from the epidermal layer of the finger to the dermis layer, as shown in fig. 7.
As can be seen from the above, the ultrasonic sensor 20 of the embodiment of the present application may be integrated inside the display screen 11 to realize the on-screen fingerprint recognition. The application of the terminal 10 using the ultrasonic sensor 20 is not limited to this. Such as the terminal 10, may utilize the ultrasonic sensor 20 to enable data transmission.
Referring to fig. 8, fig. 8 is a block diagram of a terminal according to an embodiment of the present disclosure. The terminal 10 may further include a processor 142 and a memory 144, the processor 142 and the memory 144 being electrically connected, and the processor 142 and the memory 144 may be integrated on the circuit board 14.
The memory 144 may be used for storing computer programs and data, such as for storing data to be transmitted, which may be audio data, address book data or other data. The memory 144 stores computer programs comprising instructions executable in the processor 142. The computer program may constitute various functional modules.
The processor 142 is a control center of the terminal 100, connects various parts of the entire terminal 10 using various interfaces and lines, and performs various functions of the terminal 10 and processes data by running or calling a computer program stored in the memory 144 and calling data stored in the memory 144, thereby performing overall monitoring of the terminal 10. Such as the processor 142 controlling the display 12 of the terminal 10 to display a screen, such as the processor 142 controlling the ultrasonic sensor 20 of the terminal 10 to unlock the fingerprint, such as the processor 142 controlling the terminal 10 to transmit data.
The ultrasonic sensor 20 may further include an ultrasonic transmitting section 220 and an ultrasonic receiving section 240. The ultrasonic wave transmitter 220 may transmit an ultrasonic wave signal, and the ultrasonic wave receiver 240 may receive the ultrasonic wave signal. The ultrasonic signal transmitted by the ultrasonic transmitter 220 and the ultrasonic signal received by the ultrasonic receiver 240 may be the same or different.
The terminal 10 can implement data transmission by the ultrasonic signal it transmits or receives. Such as the first terminal and the second terminal, can transceive ultrasonic signals to and from each other and realize data transmission according to the ultrasonic signals transceived to and from each other.
Referring to fig. 9, fig. 9 is a schematic view of a scenario of data transmission performed by a terminal according to an embodiment of the present application. The first terminal 10a may have a first ultrasonic sensor 20a, which may be disposed in a housing of the first terminal 10a or in a display of the first terminal 10 a. The first ultrasonic sensor 20a may include a first ultrasonic transmitting part 220a and a first ultrasonic receiving part 240a, and the first ultrasonic transmitting part 220a may transmit a first ultrasonic signal, such as an ultrasonic signal of a first waveform. The first ultrasonic wave receiving part 240a may receive a second ultrasonic wave signal, such as an ultrasonic wave signal of a second waveform. The first ultrasonic signal and the second ultrasonic signal may be the same or different.
The second terminal 10b may have a second ultrasonic sensor 20b, which may be disposed in a housing of the second terminal 10b or a display of the second terminal 10 b. The second ultrasonic sensor 20b may include a second ultrasonic transmitting part 220b and a second ultrasonic receiving part 240b, and the second ultrasonic transmitting part 220b may transmit a second ultrasonic signal, such as an ultrasonic signal of a second waveform. That is, the second ultrasonic signal transmitted by the second ultrasonic transmitter 220b can be received by the first ultrasonic receiver 240 a. The second ultrasonic wave receiving part 240b may receive a first ultrasonic wave signal, such as an ultrasonic wave signal of a first waveform. That is, the second ultrasonic wave receiving unit 240b can receive the first ultrasonic wave signal transmitted from the first ultrasonic wave transmitting unit 220 a.
Among them, the ultrasonic signal of the first waveform may be various shapes. The ultrasonic signal of the first waveform may last for a preset duration, such as 1 millisecond, 2 milliseconds, 3 milliseconds, etc. of the ultrasonic signal of the first waveform. The first ultrasonic wave transmitting part 220a may transmit a plurality of ultrasonic wave signals of the first waveform, such as the first ultrasonic wave transmitting part 220a may transmit 8 ultrasonic wave signals of the first waveform, 10 ultrasonic wave signals of the first waveform, and the like. Wherein, the interval duration of two adjacent first waveforms may be 1 millisecond, 2 milliseconds, 3 milliseconds, etc. In some embodiments, the duration of the first waveform may be equal to the interval duration of two adjacent first waveforms.
Likewise, the ultrasonic signal of the second waveform may be of various shapes. The ultrasonic signal of the second waveform may last for a preset duration, such as 1 millisecond, 2 milliseconds, 3 milliseconds, etc. of the ultrasonic signal of the second waveform. The second ultrasonic wave transmitting part 220b may transmit a plurality of ultrasonic wave signals of the second waveform, such as the second ultrasonic wave transmitting part 220b may transmit 8 ultrasonic wave signals of the second waveform, 10 ultrasonic wave signals of the second waveform, and the like. Wherein, the interval duration of two adjacent second waveforms may be 1 millisecond, 2 milliseconds, 3 milliseconds, etc. In some embodiments, the duration of the second waveform may be equal to the interval duration of two adjacent second waveforms.
When data needs to be transmitted, a terminal such as the first terminal 10a may determine, via its processor, the data to be transmitted, such as audio data, address book data, etc. The processor of the first terminal 10a may, however, control the first ultrasonic transmission section 220a to transmit the first ultrasonic signal according to the determined data to be transmitted. The first ultrasonic signal may be transmitted to the second terminal 10 b. If the processor of the second terminal 10b controls the second ultrasonic wave receiving unit 240b to receive the first ultrasonic wave signal, the processor of the second terminal 10b may control the second ultrasonic wave transmitting unit 220b to transmit the second ultrasonic wave signal according to the received first ultrasonic wave signal, and the second terminal 10b may transmit the second ultrasonic wave signal to the first terminal 10 a. The processor of the first terminal 10a may control the first ultrasonic receiving part 240a to receive the second ultrasonic signal fed back by the second terminal 10 b. Further, the processor of the first terminal 10a may transmit data to be transmitted to the second terminal 10b according to the second ultrasonic signal. Therefore, data transmission between the two terminals is realized, the data transmission can be realized by realizing the communication connection of the two terminals without additional manual control, and the operation of a user is more convenient.
It should be noted that, when the processor of the second terminal 10b controls the second ultrasonic receiving part 240b to receive the first ultrasonic signal, the processor of the second terminal 10b may compare the first ultrasonic signal with a preset ultrasonic signal, and when the first ultrasonic signal is the same as the preset ultrasonic signal, the processor of the second terminal 10b controls the second ultrasonic receiving part 220b to send the second ultrasonic signal. And if the first ultrasonic signal is different from the ultrasonic signal preset in the second terminal 10b, the processor of the second terminal 10b does not control the second ultrasonic transmitting part 220b to transmit the second ultrasonic signal.
It should be noted that, when the processor of the first terminal 10a controls the first ultrasonic receiving part 240a to receive the second ultrasonic signal, the processor of the first terminal 10a may compare the second ultrasonic signal with the first preset ultrasonic signal, and when the first ultrasonic signal is the same as the first preset ultrasonic signal, the processor of the first terminal 10a controls the first terminal 10a to transmit the data to be transmitted to the second terminal 10 b. And if the second ultrasonic signal is different from the first preset ultrasonic signal in the first terminal 10a, the first terminal 10a controls the first terminal 10a not to transmit data to be transmitted to the second terminal 10 b.
It is understood that if the received second ultrasonic signal of the first terminal 10a is different from the first preset ultrasonic signal, the first terminal 10a may regenerate the first ultrasonic signal at a preset time interval. Such as 100 milliseconds apart, 120 milliseconds apart, etc.
It is also understood that, during the process of the first terminal 10a receiving the second ultrasonic signal, the first terminal 10a may first determine whether it has received the second ultrasonic signal, and if the first terminal 10a has not received the second ultrasonic signal within a preset time, the processor of the first terminal 10a may transmit the first ultrasonic signal at intervals of the preset time, such as intervals of 100 milliseconds, 120 milliseconds, etc. And if the first terminal 10a receives the second ultrasonic signal, the second ultrasonic signal may be compared with the first preset ultrasonic signal to perform control according to the comparison result.
Therefore, according to the embodiment of the application, fingerprint unlocking can be achieved through the ultrasonic sensor 20, data transmission can be achieved, and the use of a user is facilitated.

103, the first terminal 10a receives the second ultrasonic signal fed back by the second terminal 10 b. After the first ultrasonic signal is received by the first terminal 10a, the processor of the second terminal 10b may control the second ultrasonic receiving part 240b of the ultrasonic sensor 20b to receive the first ultrasonic signal.
