Embodiment Construction
[0025] The invention provides a device embedded with a fingerprint module and a touch screen. By embedding the fingerprint module on the touch screen, there will be no gaps in structure. The hardware connection adopts a unified interface to connect with the central processing unit, and the fingerprint module The chips and peripheral circuits of the group are integrated into the LCM (LCD display module), which saves the independent connector of the fingerprint module, saves the space inside the mobile phone and the PCB board, and avoids bad problems caused by static electricity and assembly. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The invention discloses a touch screen fingerprint module embedding device. The touch screen fingerprint module embedding device is connected with a central processing unit and comprises a fingerprint module, an LCM (liquid crystal module) and a connector, wherein the LCM comprises a touch screen cover plate, a circuit board and a metal substrate, the fingerprint module is arranged between the touch screen cover plate and the metal substrate, the connector is arranged on the circuit board of the LCM, the signal lines of the fingerprint module and the LCM are electrically connected with the connector, and the connector is electrically connected with the central processing unit; signals output by the fingerprint module and the LCM interact data with the central processing unit through the connector. The fingerprint module is embedded into a touch screen and shares one connector with the LCM. The touch screen fingerprint module embedded device can structurally avoid gaps, solve the problem of failure of the fingerprint module due to static electricity, and save an independent connector of an existing fingerprint module as well as the internal space of a mobile phone and the space of a circuit board, thereby solving the problems of static electricity, poor assembly and interface space occupation.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a device embedded with a fingerprint module and a touch screen. Background technique [0002] As an electronic consumer product, smart phones occupy an important position in the work and life of the majority of users. Since the advent of smart phones with fingerprint recognition function, fingerprint recognition has gradually become the wind vane of powerful manufacturers and flagship new phones. The application of fingerprint recognition on smart phones has been popularized unprecedentedly, and front or rear fingerprint recognition has gradually become a necessary feature of high-end mobile phone products. [0003] At present, there are many mobile phones that support fingerprint recognition in the market, among which iPhone5s / 6 / 6 Plus / 7 is the representative of front fingerprint recognition mobile phones with the best experience. In the Android camp, manufacturers such as...
