Description

Fingerprint identification device under a kind of condenser type screen
Technical field
The utility model belongs to fingerprint identification device under fingerprint identification technology field more particularly to a kind of condenser type screen.
Background technique
Fingerprint identification technology is the bio-identification mode of current most mainstream.Shield lower fingerprint identification technology, is also stealthy fingerprint Technology;It is the new technology by completing fingerprint recognition unlocking process below screen glass, is mainly penetrated using ultrasonic wave, optics etc. Technology can penetrate a variety of different materials, to achieve the purpose that identify fingerprint.
But need light source to be identified when fingerprint identification device uses optical mode under existing screen, it can be only applied to The screen of OLED, is not available on the lcd screen;When fingerprint identification device uses ultrasonic wave mode under existing screen, screen refers to down Line identifies that the processing of equipment is complicated, at high cost.
Utility model content
In order to overcome the shortcomings of art methods, the purpose of this utility model is that proposing fingerprint under a kind of condenser type screen Identification device can effectively realize the identification for shielding lower fingerprint, and processing technology is simple, at low cost and small in size, can be suitable for more Kind screen.
In order to achieve the above object, the utility model is using technical solution: fingerprint identification device under a kind of condenser type screen, packet Include touch screen panel, fingerprint screen drive integrated circult, touch screen drive integrated circult, control chip and fingerprint induction touch panel face Plate;
In the fingerprint induction touch panel panel insertion touch screen panel, and pass through ITO electro-conductive glass for the fingerprint sense Answer touch screen panel cuttage in the disconnection channel of touch screen panel;The fingerprint screen drive integrated circult is electrically connected to fingerprint sense Touch screen panel is answered, the touch screen drive integrated circult is electrically connected to touch screen panel;The control chip is respectively connected to 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 Line induction touch panel panel 6 carries out fingerprint recognition.
As the prioritization scheme of above-described embodiment, the touch screen drive integrated circult 4 include touch screen driving chip and Data acquisition circuit;Realize the data acquisition and display driving of touch screen panel 1.
In order to better understand the utility model, primary complete description is made to the working principle of the utility model below:
Utilize the touch sensible for the touch screen panel 1 that ITO technique is realized;By COF flexible encapsulating substrate 2, it is used for ITO Line is connected with driving IC;The fingerprint screen drive integrated circult 3 controls fingerprint induction touch panel panel 6, the touch screen driving Integrated circuit 4 controls touch screen panel 1;Coordinate fingerprint by control chip 5 and touch screen works;It is realized using ITO technique Fingerprint induction region lower than 508DPI.
