Abstract

The invention discloses a touch-control panel serving the function of fingerprint recognition. The touch-control panel comprises a touch-control layer and a fingerprint sensing layer, wherein the touch-control layer is used for detecting the specific positions indicated by fingers; the fingerprint sensing player is arranged below the touch-control layer, and comprises a storage unit, a plurality of receiving modules and a plurality of transmitting modules and control modules; the storage unit is used for storing first fingerprint data corresponding to the fingers; and each receiving module isrespectively corresponding to one of the transmitting module; according to the specific positions indicated by the fingers on the touch-control layer, one of the transmitting modules transmits signals which are reflected to the corresponding receiving module via the fingers; and the control modules are used for converting the signals received by the receiving modules into second fingerprint data,and identifying whether the second fingerprint data are the first fingerprint data stored in the storage unit.

Description

technical field [0001] The invention relates to a touch panel, and in particular to a touch panel with fingerprint recognition function. Background technique [0002] If the electronic device needs to authenticate the user, it is common practice to set a specific password. The user must input the correct password, and the electronic device can only be used after the authentication is successful. In recent years, more and more electronic devices use fingerprint recognition devices to identify users. Because the fingerprint has a high degree of singleness, that is, the fingerprint identification device only needs to record the user's fingerprint, and the user does not need to remember a specific password, thus avoiding the risk of the password being stolen or cracked. [0003] In addition, the application of the touch panel is quite common, such as a tablet PC or a bank ATM machine. If the user can directly use the touch panel for fingerprint identification, it will be more...
