Problems solved by technology
[0006] When performing fingerprint identification through a fingerprint identification sensor, the distance between the fingerprint surface of a person's finger and the fingerprint identification sensor cannot be too far. If the distance is too far, it will be difficult to form an accurate fingerprint pattern.

The invention provides a fingerprint recognition sensor, an integrated component and a terminal device. The fingerprint recognition sensor comprises a substrate, an impressing layer formed on the substrate and fingerprint recognition sensing elements, wherein a plurality of grooves are formed in the surface of the impressing layer, and the fingerprint recognition sensing elements are contained in the grooves. Each fingerprint recognition sensing element comprises at least one first sensing electrode, a plurality of first driving electrodes, at least one second sensing electrode and a plurality of second driving electrodes, wherein the first driving electrodes are arranged side by side at intervals and arranged opposite to the at least one first sensing electrode in a spaced mode so as to define a plurality of first detection gaps, the at least one second sensing electrode is roughly perpendicular to the at least one first sensing electrode, the second driving electrodes are arranged side by side at intervals and arranged opposite to the at least one second sensing electrode in a spaced mode so as to define a plurality of second detection gaps, and the second driving electrodes and the first driving electrodes are arranged in the two directions roughly perpendicular to each other.
Description
technical field [0001] The invention relates to the technical field of biological identification, in particular to a fingerprint identification sensor, an integrated component and a terminal device. Background technique [0002] In recent years, with the development of storage technology, terminal devices such as smart phones and tablet computers store a large amount of personal information and other important data, and its security has become more important. At present, passwords, graphics and other forms are often used to realize the password protection of its terminal equipment. [0003] However, for encryption methods such as passwords and graphics, users need to remember the set passwords and / or graphics; in addition, there is a danger of password disclosure in public places. In order to improve security, it is often necessary to increase the complexity of passwords and graphics, which undoubtedly further increases the difficulty of user memory, causing conflicts betwe...
