Fig. 1 is a schematic diagram of a touch detection device with fingerprint recognition function according to an embodiment of the invention. The touch detection device 100 includes a sensing electrode 110, a mode selection circuit 120, a touch detection circuit 130, and a fingerprint identification circuit 140. The touch detection circuit 130 and the fingerprint recognition circuit 140 are coupled to the mode selection circuit 120, and the mode selection circuit 120 selects the touch detection circuit 130 or the fingerprint recognition circuit 140 to be coupled to the sensing electrode 110 according to a control signal. When the mode selection circuit 120 selects the touch detection circuit 130 to be coupled to the sensing electrode 110, the user touch signal captured by the sensing electrode 110 is transmitted to the touch detection circuit 130 through the mode selection circuit 120 to perform touch position detection. When the mode selection circuit 120 selects the fingerprint identification circuit 140 to be coupled with the sensing electrode 110, the fingerprint image data of the user captured by the sensing electrode 110 is transmitted to the fingerprint identification circuit 140 for comparison through the mode selection circuit 120.
The sensing electrode 110 further includes a plurality of first axial sensing electrodes 111 arranged along a transverse direction (e.g., an X-axis direction), and a plurality of second axial sensing electrodes 112 arranged along a longitudinal direction (e.g., a Y-axis direction), wherein the first axial sensing electrodes 111 and the second axial sensing electrodes 112 are arranged to cross each other, and a transparent insulating layer is disposed between the first axial sensing electrodes 111 and the second axial sensing electrodes 112 to electrically isolate the first axial sensing electrodes 111 and the second axial sensing electrodes 112, so that the first axial sensing electrodes 111 and the second axial sensing electrodes 112 are insulated from each other and are arranged to cross each other. And each first axial sensing electrode 111 is connected to a first axial driving line 113 to couple to the mode selection circuit 120 through the first axial driving line 113. Each second axial sense electrode 112 is connected to a second axial drive line 114 for coupling to a mode selection circuit 120 via the second axial drive line 114. In a preferred embodiment, since the touch position detection and the fingerprint image data capture are performed simultaneously on the sensing electrode 110, in order to obtain a certain resolution of the captured fingerprint image data, in a preferred embodiment, the electrode width W of the first axial sensing electrode 111 and the second axial sensing electrode 112 is preferably 50 μm, and the distance d between any two adjacent electrodes is preferably 20 μm, as shown in the enlarged view of fig. 2.
On the other hand, when performing touch position detection, for example, touch position detection is performed by a mutual capacitance method, a driving signal is sequentially sent to drive one of the axial sensing electrodes, and an induction signal on the other axial sensing electrode is received one by one to complete addressing of each staggered point, so that the resolution of the sensing electrode affects the scanning detection time. In order to avoid the decrease of the touch response speed caused by the increased resolution of the sensing electrodes for capturing the fingerprint image data, in a preferred embodiment, a plurality of first switching elements are further disposed in the mode selection circuit 120, so that the same plurality of sensing electrodes adjacent in the axial direction are connected in parallel to each other as a single sensing electrode, and the resolution of the sensing electrode 110 is changed from the first resolution used in fingerprint identification to the second resolution used in touch detection, wherein the first resolution is greater than the second resolution, so as to increase the touch response speed in performing touch position detection.
Fig. 3 is a schematic diagram of a mode selection circuit according to a preferred embodiment of the invention, in which the resolution of the second axial sensing electrode 112 is changed, however, the same switching circuit structure can be used for switching the first axial sensing electrode 111. According to the present embodiment, a first switching element 121 is disposed between two adjacent second axial driving lines 114, so that the first switching element 121 is turned on when detecting the touch position, so that two adjacent second axial sensing electrodes 112 form a parallel structure to serve as a sensing electrode, and simultaneously receive the driving signal transmitted by the touch detection circuit 130 to convert the resolution of the second axial sensing electrodes 112 from the first resolution used when fingerprint identification is performed to a smaller second resolution to increase the touch response speed. In one embodiment, for example, the sensing electrodes with a width of 400 μm are formed, and since the electrode width of each second axial sensing electrode 112 is 50 μm and the spacing between the electrodes is 20 μm, a parallel structure is formed by combining 5 second axial sensing electrodes 112 as a group to be used as a sensing electrode, and the resolution is converted from the first resolution used in fingerprint recognition to the smaller second resolution. Therefore, the plurality of second axial sensing electrodes 112 are grouped in groups of 5 second axial sensing electrodes 112, and the first switching elements 121 in each group are turned on, so that the 5 second axial sensing electrodes 112 in the group form a parallel structure to serve as a sensing electrode together, and are coupled to the touch detection circuit 130 through a second switching element 122. Therefore, the touch detection circuit 130 can transmit the driving signal to the same set of 5 parallel second axial sensing electrodes 112 through the second switching component 122 for touch position detection. The number of the second axial sensing electrodes 112 connected in parallel is not limited to this embodiment, and can be adjusted according to actual usage.
In addition, the second switching elements 122 disposed between each second axial driving line 114 and the touch detection circuit 130 can conduct the corresponding second switching elements 122 according to the grouping condition of the second axial sensing electrodes 112, so that the touch detection circuit 130 can transmit the driving signal to the second axial sensing electrodes 112 connected in parallel in the same group through the second switching elements 122. In addition, in order to coordinate-transform to locate the touch position in coordination with the change of the resolution of the sensing electrodes, for example, taking a touch panel with 1000 second axis sensing electrodes 112 as an example, if the positions of the original 1000 second axis sensing electrodes 112 are respectively 1-1000, and then grouping with 5 second axis sensing electrodes 112 as a group, the coordinate-transform is performed in a 5:1 ratio, so the new sensing electrode position will be 1-200.
On the other hand, a third switching element 123 is further disposed between each second axial driving line 114 and the fingerprint identification circuit 140, so that the second axial sensing electrode 112 can be coupled to the touch detection circuit 130 or the fingerprint identification circuit 140 by switching the first switching element 121, the second switching element 122 and the third switching element 123. For example, when the first switching element 121 and the second switching element 122 are turned on and the third switching element 123 is turned off, the second axial sensing electrode 112 is coupled to the touch detection circuit 130 for detecting the touch position. Conversely, if the third switching element 123 is turned on and the first switching element 121 and the second switching element 122 are turned off, the second axial sensing electrode 112 is coupled to the fingerprint identification circuit 140 to perform the comparison of the fingerprint image data. In other words, the mode selection circuit 120 can select the touch detection circuit 130 or the fingerprint recognition circuit 140 to be coupled with the sensing electrode 110, and can change the resolution of the sensing electrode 110 to increase the touch response speed during the touch position detection.
In a preferred embodiment, the present invention drives the sensing electrode 110 to capture fingerprint image data in a mutual capacitance manner. In the structure of the sensing electrode with the first axial sensing electrode 111 facing the finger print of the user, when the mutual capacitance driving is performed, the first axial sensing electrode 111 is sequentially driven and receives the sensing signals on the second axial sensing electrode 112 one by one, and since the capacitance is inversely proportional to the distance, when the finger of the user is placed on the first axial sensing electrode 111, the portion of the ridge, which contacts with the first axial sensing electrode 111, has a larger capacitance, the portion of the groove has a smaller capacitance, and the fingerprint identification circuit 140 can identify the capacitance by receiving the sensing signals on the second axial sensing electrode 112 to sense the fingerprint image data. In another embodiment, the invention can also adopt a self-capacitance mode to capture fingerprint image data, in which the first axial sensing electrode 111 is sequentially driven, and the second axial sensing electrode 112 is grounded, so that the fingerprint identification circuit 140 can sense fingerprint image data by receiving the capacitance change between the first axial sensing electrode 111 and the second axial sensing electrode 112, i.e. the ground.
In addition, referring to fig. 1 again, in one embodiment, the fingerprint image capturing area may be defined in the sensing electrode 110 in advance. The fingerprint image capturing area may be defined in any portion of the sensing electrode 110. When the mobile device is triggered, the fingerprint capturing area is correspondingly displayed on the defined position of the touch panel, and the mode selection circuit 120 selects the fingerprint identification circuit 140 to be coupled with the sensing electrode 110, so that a user can press a finger on the fingerprint image capturing area on the touch panel, after capturing the fingerprint image data of the user by the sensing electrode 110, the fingerprint image data is transmitted to the fingerprint identification circuit 140 by the mode selection circuit 120 for comparison, and the operation function of the mobile communication device is started when the fingerprint is correct. When the mobile communication device is turned on, the mode selection circuit 120 selects the touch detection circuit 130 to be coupled to the sensing electrode 110, so as to perform touch position detection.
Therefore, the integrated fingerprint identification device directly uses the sensing electrode for touch detection as the fingerprint identification electrode, does not need to additionally arrange the fingerprint identification electrode on the mobile device, and can maximize the displayable area of the mobile device because the non-display area for fingerprint identification can be removed. Furthermore, since the fingerprint identification electrode is not required to be manufactured additionally, the original electrode manufacturing flow is not required to be changed, the manufacturing process is quite convenient, and the manufacturing cost is saved.
While the invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto but may be variously modified and modified by those skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is therefore as defined by the appended claims.
