A typical fingerprint recognition device usually includes a fingerprint recognition chip and a sensor composed of a plurality of sensing elements.

The first combination method is to etch electrode patterns on the surface metal layer of the integrated circuit to which the fingerprint identification chip belongs to realize these sensing elements, that is, the fingerprint identification chip and the sensor are directly integrated into the same integrated circuit. The second combination method is to arrange these sensing elements on a substrate (such as a light-transmitting substrate, a plastic substrate or a circuit board), and then package them in a fine-pitch ball grid array (FBGA) form The substrate and the integrated circuit to which the fingerprint recognition chip belongs are packaged together.

detailed description

A specific embodiment according to the present invention is a fingerprint identification device, and the schematic diagram of the relative relationship between the configuration of its components is shown in FIG. 1(A). The fingerprint identification device 100 includes a transparent substrate 110 , a sensor 120 composed of a plurality of sensing elements, a set of wires 130 and a fingerprint identification chip 140 . As shown in FIG. 1(A), a plurality of sensing elements in the sensor 120 , wires 130 and a fingerprint identification chip 140 are disposed on the upper surface 110A of the light-transmissible substrate 110 . For example but not limited thereto, the material of the transparent substrate 110 may be glass, plastic or synthetic film.

FIG. 1(B) is a side view of the fingerprint recognition device 100 . In this embodiment, the sensor 120 includes a covering layer 120A and an electrode layer 120B stacked one above the other. The cover layer 120A is used to withstand user's touch to protect the electrode layer 120B, and its material can be but not limited to glass or hard coating. The electrode layer 120B can be directly formed on the light-transmittable substrate 110 . FIG. 2 presents a detailed implementation example of the electrode layer 120B. The electrode layer 120B is a stacked structure, including a first metal layer M1 , a first insulating layer IN1 , a second metal layer M2 , a second insulating layer IN2 , and an adhesive layer AD from bottom to top. The first metal layer M1 can be fabricated to include a plurality of receiving electrode patterns, and the second metal layer M2 can be fabricated to include a plurality of driving electrode patterns, or they can be exchanged with each other. The receiving electrodes and the driving electrodes are in pairs to form the above-mentioned multiple inductive elements. For example, the sensor 120 can be designed to include 100*100 sensing elements arranged in a matrix. The size of the sensing element, shape, quantity and arrangement of the electrodes can be determined by the circuit manufacturer according to the size of the sensor 120 and the required sensing precision. In order to avoid too much confusion in the drawing, FIG. 1(A) only presents 6*6 sensing elements as an illustration example. In practice, the material of the adhesive layer AD can be optical clear adhesive (OCA) with good light transmittance, which is used to bond the covering layer 120A and the electrode layer 120B. In practice, if the material of the adhesive layer AD has sufficient insulating capability, the second insulating layer IN2 can also be omitted.

The wire 130 may include a plurality of metal traces formed on the upper surface 110A. The fingerprint recognition chip 140 is connected with the sensor 120 through the wire 130 . The fingerprint recognition chip 140 is responsible for driving the sensing elements in the sensor 120, receiving sensing results generated by these sensing elements, and judging a user's fingerprint accordingly. In practice, the fingerprint recognition chip 140 can be an integrated circuit chip with a flip-chip package, and is bonded to a plurality of conductive points on the light-transmittable substrate 110 through conductive glue, thereby connecting to the wire 130 . Compared with the prior art where the substrate where the sensing element is located and the fingerprint identification chip are integrated into a fine-pitch ball grid array (FBGA) package in a packaging factory, the implementation of the present invention has the advantage of saving packaging costs. In practical applications, the fingerprint identification chip 140 may include but not limited to analog-to-digital converters, noise filter circuits, comparators, memory and other components. It should be noted that the driving method of the sensing element and the method of judging the user's fingerprint according to the sensing result are known to those skilled in the art, and will not be repeated here.

Looking at FIG. 1(A), FIG. 1(B) and FIG. 2 , in the fingerprint recognition device 100, both the light-transmissive substrate 110 and the covering layer 120A can be designed to have good light transmission, and the sensor 120 The first insulating layer IN1 , the second insulating layer IN2 and the adhesive layer AD can also be realized by materials with good light transmittance. On the other hand, the hollowed-out parts of the electrode patterns of the first metal layer M1 and the second metal layer M2 in the sensor 120 can also be penetrated by light. Therefore, if the electrode pattern in the sensor 120 is properly designed so that it contains more hollow parts, or even the electrodes are made of transparent conductive materials, the direction Z marked in FIG. A considerable part of the light traveling in the direction Z can pass through the fingerprint identification device 100 . On the other hand, even though the conducting wire 130 itself is composed of a plurality of opaque metal thin wires, the gaps between the wires can still allow light to penetrate. Therefore, from the perspective of the user, except for the location of the fingerprint identification chip 140 , other parts of the fingerprint identification device 100 can have a considerable degree of light transmission.

Compared with the prior art, the light transmission property of the fingerprint identification device 100 can provide designers of various products with greater design flexibility. For example, if the fingerprint recognition device 100 is applied in an access control system, the light-transmissive substrate 110 can be the glass door itself. In practical applications, the fingerprint identification chip 140 can be connected to other external circuits through connecting wires (not shown) provided on the transparent substrate 110, such as golden fingers, to receive power supply or use The result of fingerprint judgment is provided to the follow-up circuit.

FIG. 3 presents a side view of a variant of the fingerprint identification device 100 . The main difference between the fingerprint identification device 200 and the fingerprint identification device 100 is that the fingerprint identification device 200 further includes a light emitting module 150 . The light emitting module 150 is disposed on a light emitting substrate 160 and can be realized by using one or more light emitting diode elements, but not limited thereto. As shown in FIG. 3 , the light-emitting substrate 160 is substantially parallel to the light-transmissible substrate 110 and is opposite to the lower surface 110B of the light-transmittable substrate 110 . The light provided by the light emitting module 150 can pass through the transparent substrate 110 and the sensing area 120, and reach the user's line of sight. For example, the light emitted by the light emitting module 150 can be used as an auxiliary indicator, so that the user can easily notice the location of the sensing area 120 . Practically, the light emitting module 150 may include a control unit and a light emitting diode array (consisting of a plurality of light emitting diodes with the same or different light colors). The control unit is responsible for controlling the switch, brightness or color of these LEDs according to the operation mode of the fingerprint identification device 200 .

FIG. 4(A) presents a schematic diagram of a variant of the fingerprint identification device 200 . The fingerprint identification device 300 further includes a controller 170 disposed on a main circuit board 175 and coupled to the fingerprint identification chip 140 and the light emitting module 150 through connection lines 171 and 172 respectively. In practical applications, the main circuit board 175 can be a printed circuit board, which is electrically connected to the transparent substrate 110 and the light-emitting substrate 160 through a flexible circuit board or a flexible cable. In other words, each of the connection lines 171 and 172 may include several sections of traces on the flexible circuit board, the main circuit board 175 , the light-transmissible substrate 110 and the light-emitting substrate 160 . The connection lines 171 and 172 may also include power lines, which are responsible for transmitting power from the main circuit board 175 to the fingerprint recognition chip 140 and the light emitting module 150 .

The controller 170 is used for controlling the light emitting module 150 according to the user's fingerprint determined by the fingerprint identification chip 140 . For example, a specific fingerprint pattern can be stored in the controller 170 . When the fingerprint of the user currently detected by the fingerprint recognition chip 140 matches the specific fingerprint pattern, the controller 170 controls the light emitting module 150 to emit light of a certain color (such as green) and executes corresponding actions when the identity authentication is successful (such as unlock the mobile phone). Relatively, when the user's fingerprint detected by the current fingerprint recognition chip 140 does not conform to the specific fingerprint pattern, the controller 170 controls the light emitting module 150 to emit light of another color (for example, red), and executes the authentication process when the identity authentication is unsuccessful. Corresponding action (for example, displaying a text message of unlock failure on the screen of the mobile phone). In practice, the controller 170 can be implemented as fixed and/or programmable digital logic circuits, including programmable logic gate arrays, application-specific integrated circuits, microcontrollers, microprocessors, digital signal processors, and other necessary circuits .

Alternatively, as shown in FIG. 4(B), the functions of the controller 170 can be distributed and realized in the control unit (not shown) of the fingerprint identification chip 140 and the light emitting module 150 itself. In other words, the light-emitting module 150 can be connected to the fingerprint recognition chip 140 through the connection line 173 , and is directly controlled by the fingerprint recognition chip 140 to perform the above-mentioned task of emitting light of different colors.

FIG. 5(A) shows an example of a housing of the fingerprint identification device 300 . In this example, the light-transmissive substrate 110 , the light-emitting substrate 160 , the main circuit board 175 and the components thereon are all accommodated inside the casing 510 . The top wall 511 of the housing 510 has an opening 511A for exposing the sensing surface of the covering layer 120A for receiving a user's touch. As shown in FIG. 5(A), the height of the fingerprint recognition chip 140 is generally higher than the sensing area 120 in the reference direction Z' perpendicular to the transparent substrate 110 and away from its upper surface. If the thickness of the housing 510 is designed based on the height of the fingerprint identification chip 140, the sensing surface of the covering layer 120A will be lower than the top wall 511 of the housing 510 in the reference direction Z'. In accordance with this relative height relationship, the housing 510 can be designed such that the opening 511A has an inclined portion 512 , which slopes from the bottom of the top wall 511 to the sensing surface of the covering layer 120A. Compared with adopting a vertical side wall at the junction of the opening 511A and the covering layer 120A, the inclined portion 512 can make the user more comfortable when pressing the covering layer 120A.

Please refer to Figure 5(B). In an embodiment where the casing 510 has conductivity, the fingerprint identification device 300 may further include a conductive element 520 electrically connected between the inside of the casing 510 and the main circuit board 175 . More specifically, the conductive element 520 is electrically connected to a fixed voltage terminal on the main circuit board 175 , such as a ground terminal. In practical applications, the housing 510 may have weak conductivity because it is coated with metal spray paint. Even in the case of weak conductivity, because the shell 510 can be equivalent to a considerable capacitor, connecting the shell 510 to a fixed voltage terminal on the main circuit board 175 can help eliminate the background noise detected by the fingerprint recognition chip 140 , Improve the accuracy of the test results. In practice, the conductive element 520 can be, but not limited to, a conductive foam or a metal shrapnel.

FIG. 6(A) presents another housing example of the fingerprint recognition device 300 . In this example, the top wall 611 of the casing 610 also has an opening for exposing the sensing surface of the covering layer 120A. The characteristic of this embodiment is that, in the reference direction Z′ perpendicular to the light-transmittable substrate 110, the thickness of the cover layer 120A is deliberately increased so that the sensing surface is roughly equal to the height of the top wall 611 of the housing, that is, the cover layer 120A is approximately close to the opening of the top wall 611 . The advantage of this approach is that a full planar mechanism design can be achieved. In practice, it is convenient to control the thickness of the cover layer 120A by using a glass plate or a hard coating to realize the cover layer 120A. It should be noted that the effect of making the sensing surface of the covering layer 120A roughly equal to the height of the top wall 611 can also be achieved by thickening the electrode layer 120B or partially thickening the transparent substrate 110 below the electrode layer 120B.

As shown in FIG. 6(B), in an embodiment where the casing 610 has conductivity, a conductive element 620 may also be provided between the inner side of the casing 610 and the main circuit board 175 to improve the accuracy of the detection result of the fingerprint recognition chip 140. sex.

Another specific embodiment according to the present invention is a touch device with a fingerprint recognition function, and the schematic diagram of the relative relationship between the component configurations is shown in FIG. 7(A). The touch device 700 includes a light-transmissible substrate 710, a plurality of first sensing elements located in a first area 711, a plurality of second sensing elements located in a second area 712, a set of first wires 731, a set of first sensing elements Two wires 732 , a fingerprint recognition chip 740 , a touch control circuit 760 , and a display 750 (shown in FIG. 7(C) ) disposed under the light-transmittable substrate 710 .

In this embodiment, the first area 711 and the second area 712 jointly form a rectangular touch area. As shown in FIG. 7(B), in accordance with the shape and position of the first area 711, the outline of the second area 712 is a rectangle with a concave area. Practically, the second sensing elements can be multiple sets of electrodes made of transparent or light-permeable conductive materials. The dotted lines in FIG. 7(B) are used to indicate the intervals between the second sensing elements. In practice, the size, electrode shape, quantity and arrangement of these second sensing elements can be determined by the circuit manufacturer according to the size of the touch device 700 and the required sensing fineness and sensing resolution.

As shown in FIG. 7(A), the plurality of first sensing elements, the plurality of second sensing elements, the first wire 731, the second wire 732, the fingerprint identification chip 740 and the touch circuit 760 are all arranged on a light-transmittable The upper surface of the substrate 710. The fingerprint recognition chip 740 is connected to the first sensing elements in the first region 711 through the group of first wires 731 . The touch circuit 760 is connected to the second sensing elements in the second area 712 through the set of second wires 732 . The fingerprint identification chip 740 is responsible for driving the first sensing elements in the first region 711 and receiving multiple first sensing results generated by the first sensing elements. The touch circuit 760 is responsible for driving the second sensing elements in the second region 712 and receiving a plurality of second sensing results generated by the plurality of second sensing elements.

FIG. 7(C) is a cross-sectional view of the touch device 700 along the section line 799 . The size of the aforementioned display 750 disposed under the light-transmittable substrate 710 may be approximately the same as the touch area jointly formed by the first area 711 and the second area 712 , and is located directly below the touch area. Similar to the sensor 120 in FIG. 1 , the first area 711 in FIG. 7(A) and FIG. 7(C) also has a considerable degree of light transmission, so that the light emitted by the display 750 can pass through the first area 711 . Since both the first area 711 and the second area 712 are transparent (although the degree of light transmission may not be exactly the same), the user can completely see the picture presented by the display 750 through the first area 711 and the second area 712 .

When the touch device 700 is in the fingerprint recognition mode, the display 750 can display patterns or lines under the first area 711 to indicate the range of the first area 711 for the user's reference to know where to press the fingerprint. Same as the fingerprint recognition chip 140 in FIG. 1 , the fingerprint recognition chip 740 will judge a user's fingerprint according to these first sensing results. In this case, the touch circuit 760 may not work temporarily.

In this embodiment, the fingerprint identification chip 740 and the touch control circuit 760 can work together, so that the touch range formed by the first area 711 and the second area 712 is equivalent to a complete rectangular touch area. More specifically, when the touch control device 700 needs to detect a wider range of user touch actions, the fingerprint identification chip 740 is responsible for driving the first sensing elements in the first area 711 and receiving multiple signals generated by these first sensing elements. a first sensing result, and the touch circuit 760 is responsible for driving the second sensing elements in the second area 712 and receiving the second sensing results generated by the second sensing elements. Moreover, the first sensing results received by the fingerprint identification chip 740 will be provided to the touch circuit 760 . Then, the touch circuit 760 can determine a user's touch action occurring within the rectangular touch area according to the plurality of first sensing results and the plurality of second sensing results. In practice, the sensing results generated by the fingerprint recognition chip 740 and the touch circuit 760 can also be provided to another back-end controller (not shown) for comprehensive analysis and processing. The back-end controller can be a central processing unit that comprehensively processes general application programs of the touch device 700 , a graphics processor dedicated to processing images displayed on the display 750 , or an independent touch fingerprint processor. Comprehensive research, judgment and processing by the back-end controller have obvious advantages in some applications. For example, if the back-end controller is a central processing unit, the central processing unit can provide the plurality of first sensing results or the plurality of second sensing results to the central processing unit in one of the fingerprint identification chip 740 and the touch control circuit 760. When the processor is used, the corresponding application program is pre-started or the corresponding data is downloaded from the memory in advance, so that part of the corresponding tasks can be processed before the user's touch action is judged, so that the user's touch The reaction speed is accelerated. In another example, if the backend controller is a graphics processor, the graphics processor can control the fingerprint recognition chip 740 to successively send a plurality of first sensing results corresponding to the sensing positions during the fingerprint recognition process. During the process of fingerprint identification, the graphics processor can not only control the display 750 to statically display patterns or lines under the first area 711, but can even dynamically display different patterns at the corresponding sensing positions to mark the corresponding sensing positions that have been identified; Naturally, this example can also be realized by using the central processing unit as the back-end controller and controlling the graphics processing unit at the same time, and similar applications can also be found when the touch circuit 760 senses continuous dynamic gestures. In addition, the back-end controller can also be dynamically implemented by one or more of the multi-core processors which are less busy.

Generally speaking, the sensing resolution required for identifying fingerprints is higher than the sensing resolution for identifying user touch actions. Practically, the number of sensing elements per unit area in the first area 711 can be designed to be higher than the number of sensing elements per unit area in the second area 712 . Therefore, when the fingerprint recognition chip 740 cooperates with the touch circuit 760 to detect the user's touch action, the touch circuit 760 can selectively use only a part (not all) of the first sensing results to represent the first area 711 Induction results. Please refer to Figure 8(A) and Figure 8(B). Taking the case where the first area 711 includes 4*4 first sensing elements per unit area and the second area 712 includes 2*2 second sensing elements per unit area, the touch circuit 760 can only use the The sensing results of the four first sensing elements marked with oblique lines in 8(C) represent the sensing results in this unit area, thereby reducing the amount of data processing. For example, regarding the first sensing elements 00, 01, 10, and 11 in FIG. The sensing value of the sensing element 00 is multiplied by four to represent the sensing result in the area where the four first sensing elements are located. In other examples, the first sensing element 00 can be replaced by one of the first sensing elements 01 , 10 , 11 , or two or three of the first sensing elements 00 , 01 , 10 , 11 can be selected. In addition, the touch circuit 760 can also use the sensing quantities of the first sensing elements at different relative positions or numbers in different unit areas to calculate sensing results according to requirements.

Those with ordinary knowledge in the technical field of the present invention can understand that the various operation changes described in the introduction of the fingerprint recognition device 100 can also be applied to the touch device 700 , and the details will not be repeated here.

Different from the situation in the prior art that the touch area and the fingerprint sensing area are always separated and set independently, since the first area 711 in FIG. 7(A) can have good light transmission, the fingerprint sensing area of the touch device 700 (ie the first area 711 ) is also a part of the touch area. The advantage of this approach is that the frame of the touch device 700 outside the range of the display 750 can be reduced.

Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be defined by the claims.
