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.

Abstract

The invention discloses a touch screen with a fingerprint recognition function, a terminal device and a fingerprint recognition method. The touch screen comprises a transparent cover plate, a semiconductor film arranged on the transparent cover plate and a fingerprint sensor attached to the lower portion of the transparent cover plate, wherein semiconductor stripes are formed on the semiconductor film at intervals, the fingerprint sensor comprises a first fingerprint detection electrode and second fingerprint detection electrode, the first fingerprint detection electrode is arranged between detection electrodes of a position sensor of the touch screen and is parallel to the detection electrodes of the position sensor in a spaced mode. The touch screen can be used in a view area of the terminal device comprising the touch screen to carry out fingerprint recognition, and the detection electrodes of the fingerprint recognition sensor and the detection electrodes of the position sensor of the touch screen are made to be of the same structure.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a touch screen with a fingerprint identification function, a terminal device and a fingerprint identification method. 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 u...
