The control terminal of fingerprint screen drive integrated circult and touch screen drive integrated circult.
Further, carrying out the electrical connection by ITO electro-conductive glass line, ITO electro-conductive glass line setting is existed
On COF flexible encapsulating substrate；Under guaranteeing that entire screen touch function is unaffected, signal transfer functions are completed；Play physics guarantor
Shield submits signal transmission rate, envelope eapsulotomy, impedance matching, stress mitigation, moisture-proof effect of radiating.
Further, the control chip is MCU controller；Control performance is strong, occupies little space and at low cost.
Further, the fingerprint screen drive integrated circult includes fingerprint recognition chip；To fingerprint induction touch panel face
Plate carries out fingerprint recognition.
Further, the touch screen drive integrated circult includes touch screen driving chip and data acquisition circuit；It is real
The data acquisition and display driving of existing touch screen panel.
Using the technical program the utility model has the advantages that
The utility model is not necessarily to secondary light source and ultrasonic wave, carries out cuttage and chip drives using screen script structure
Realize the identification for shielding lower fingerprint；Processing technology is simple, at low cost and small in size；It is applied widely, a variety of screens can be suitable for.
Detailed description of the invention
Fig. 1 be the utility model a kind of condenser type screen under fingerprint identification device structural schematic diagram；
Wherein, 1 is touch screen panel, and 2 be COF flexible encapsulating substrate, and 3 be fingerprint screen drive integrated circult, and 4 be touch screen
Drive integrated circult, 5 are control chips, and 6 be fingerprint induction touch panel panel.
Specific embodiment
In order to keep the purposes, technical schemes and advantages of utility model clearer, with reference to the accompanying drawing to the utility model
It is further elaborated.
In the present embodiment, shown in Figure 1, fingerprint identification device under a kind of condenser type screen, including touch screen panel 1,
Fingerprint screen drive integrated circult 3, touch screen drive integrated circult 4, control chip 5 and fingerprint induction touch panel panel 6；
The fingerprint induction touch panel panel 6 is embedded in touch screen panel 1, and passes through ITO electro-conductive glass for the fingerprint
6 cuttage of induction touch panel panel is in the disconnection channel of touch screen panel 1；The fingerprint screen drive integrated circult 3 is electrically connected to
Fingerprint induction touch panel panel 6, the touch screen drive integrated circult 4 are electrically connected to touch screen panel 1；The control chip 5
It is respectively connected to the control terminal of fingerprint screen drive integrated circult 3 and touch screen drive integrated circult 4.
As the prioritization scheme of above-described embodiment, the electrical connection is carried out by ITO electro-conductive glass line, the ITO is led
Electric glass thread is arranged on COF flexible encapsulating substrate 2；Under guaranteeing that entire screen touch function is unaffected, signal transmission is completed
Function；It plays physical protection, submit signal transmission rate, envelope eapsulotomy, impedance matching, stress mitigation, moisture-proof effect of radiating.
As the prioritization scheme of above-described embodiment, the control chip 5 is MCU controller；Control performance is strong, occupied space
It is small and at low cost.
As the prioritization scheme of above-described embodiment, the fingerprint screen drive integrated circult 3 includes fingerprint recognition chip；To finger
