Embodiment Construction
[0026] 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 device embedded in a fingerprint module and a touch screen, which is connected to a central processing unit and includes a fingerprint module, an LCM module and a connector; the LCM module includes a touch screen cover plate, a circuit board and a metal bottom plate; the fingerprint module The group is set between the touch screen cover and the metal bottom plate, the connector is set on the circuit board of the LCM module, the signal line of the fingerprint module and the signal line of the LCM module are both electrically connected to the connector, and the connector is connected to the central processing unit. Electrical connection; the signal output by the fingerprint module and the signal output by the LCM module perform data interaction with the central processing unit through the connector. Embed the fingerprint module into the touch screen and share a connector with the LCM module. From the structural point of view, there will be no gaps, which solves the problem that static electricity makes the fingerprint module invalid, and also saves the independent connector of the existing fingerprint module, saving the space inside the mobile phone and the circuit board. Therefore, the problems of static electricity, poor assembly, and space occupied by the interface are solved.
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...
