In the present embodiment, by sharing the first drive electrode 62, the second drive electrode 65, the first induction electrode 63 and the second induction electrode 66, form a pair of line imaging devices, for generation of accurately without being out of shape fingermark image.Direction while first determining finger inswept fingerprint recognition region by the first induction electrode 63 or the second induction electrode 66 by finger, and, by comparing the signal intensity of the first induction electrode 63 and the second induction electrode 66, determine the speed of finger during inswept fingerprint recognition region (for example: obtain digit speed by calculating the mistiming of identical finger-print region by the first induction electrode 63 and the second induction electrode 66), with this, obtain fingermark image more accurately.
So, when the first capacitance plate lead-in wire 61 is by the coupling semiconductor leads 41 of charging, finger to contact semiconductor lead-in wire 41 is inputted small radio-frequency current signal, to strengthen the penetration of fingerprint electric field line to substrate 5, guarantee that the above-mentioned fingerprint recognition lead-in wire (the first drive electrode 62, the first induction electrode 63, the second drive electrode 65 and the second induction electrode 66 etc.) under substrate 5 can detect fingerprint electric field line, make the fingerprint recognition lead-in wire of substrate 5 belows to carry out fingerprint recognition by the compartment of semiconductor leads, detect fingerprint ridge or fingerprint ridge paddy.
In semiconductor composite bed 6, due to integrated multiple lead-in wire, by the mode of the line that jumps, intersect, to form insulation between lead-in wire.For example: the first capacitance plate lead-in wire 61 parallels with the first drive electrode 62 or the second drive electrode 65, many, interval the first drive electrode 62 or the second drive electrode 65 between the first adjacent capacitance plate lead-in wire 61.Insulation between first capacitance plate lead-in wire the 61 and first induction electrode 63, and insulation between the first capacitance plate lead-in wire the 61 and second induction electrode 66.The first capacitance plate lead-in wire 61 intersects with the first induction electrode 63, the second induction electrode 66 by the jump mode of line of insulation course.At the S place, line region that jumps, the second induction electrode 66 blocks the first capacitance plate and went between for 61 (as shown in Figure 6 a), local deposits transparent insulation film 68 (as shown in Figure 6 b) on the second induction electrode 66, deposit transparent conductive film 69 on transparent insulation film 68, transparent conductive film 69 and the second induction electrode 66 insulation, and the two ends of transparent conductive film 69 exceed transparent insulation film 68 to connect the first capacitance plate lead-in wire 61 being truncated, independent first capacitance plate lead-in wire 61 (as shown in Fig. 6 c) that are communicated with.
In the work of above-mentioned fingerprint recognition lead-in wire, because the first capacitance plate lead-in wire 61 is by mode and the fingerprint recognition lead wire insulation of the line that jumps, so can not affect the work of the first drive electrode 62, the second drive electrode 65, the first induction electrode 63 and the second induction electrode 66 etc., can not cause interference to the fingerprint image finally obtaining.
The present embodiment has provided the fingerprint recognition lead-in wire that forms two-wire imager, but not as limit, the fingerprint recognition lead-in wire in semiconductor composite bed 6 can be also single line imager, repeats no more herein.
Embodiment of the present utility model is as follows:
When user's finger contact is during to fingerprint recognition region 3 in the touch-screen 2 of mobile phone 1, first capacitance plate lead-in wire the 61 and second capacitance plate lead-in wire 71 detects the position of finger, transmit a signal to position transducer module, position transducer module feeds back to signal processing unit.Signal generation/receiver in signal processing unit off-position sensor.Then, signal processing unit starts radio frequency high tension module, radio frequency high tension electric current is transported to the first capacitance plate lead-in wire 61 interting between the first drive electrode 62 and the second drive electrode 65 by position transducer module, the first capacitance plate lead-in wire 61 is to the semiconductor leads 41 coupling chargings on substrate 5 surfaces, and finger obtains the little current signal of radio frequency and strengthens the penetration of its electric field line to substrate 5 from semiconductor leads 41.Signal processing unit starts fingerprint identification module C and corresponding drive electrode and induction electrode function simultaneously, carries out fingerprint recognition.After completing fingerprint recognition, signal processing unit is closed fingerprint identification module C and radio frequency high tension module, and the signal generation/receiver in the sensor assembly of open site, recovers position transducer functions of modules.Above by circuit fast switching over mode realize the alternation of fingerprint identification module and position transducer module.
Continuation, referring to figs. 1 to 8, according to another aspect of the present utility model, also provides a kind of electronic installation (portable terminals such as mobile phone, Ipad or entrance guard device) with fingerprint identification function, comprises the above-mentioned touch screen with fingerprint identification function.Wherein, 1 is mobile phone, 2 touch-screens that are mobile phone, and 3 is the fingerprint recognition region in touch-screen, H is finger sliding reference direction, slides and also can carry out fingerprint recognition in the other direction, not as limit.Substrate 5 in touch screen module A is exactly the transparent cover plate of electronic installation, and position transducer module B, fingerprint identification module C, radiofrequency signal boost module D and signal processing module E can be integrated on the mainboard of mobile phone.This electronic installation can carry out fingerprint recognition on the viewing area of the transparent cover plate of display screen, realizes principle as front, repeats no more herein.
