Fingerprint identification sensor, display screen, electronic device and function starting method

Abstract

The invention relates to the technical field of fingerprint identification and discloses a fingerprint identification sensor, a display screen, an electronic device and a function starting method. The fingerprint identification sensor comprises a substrate and a sensing layer arranged on the substrate, wherein the sensing layer comprises a plurality of driving blocks and a plurality of sensing blocks; the driving blocks and the sensing blocks are arranged at intervals to form a sensing array; the sensing layer further comprises a plurality of driving signal lines and a plurality of sensing signal lines; and the driving blocks located in a same row of the sensing array are connected to the same driving signal line, and the sensing blocks located in a same column are connected to the same sensing signal line. According to the fingerprint identification sensor, the display screen, the electronic device and the function starting method, fingerprint identification and operation can be realized by enabling a user to perform touch and press directly in any position of a screen, so that fingerprint identification and touch integration is realized and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification sensor, a display screen, electronic equipment and a function starting method. Background technique [0002] Current electronic devices, such as mobile phones or tablet computers, are generally equipped with touch screens and fingerprint identification modules. That is, capacitive touch and fingerprint recognition are separately set in two areas of the housing, which means that the screen area is only used for touch, and fingerprint recognition is realized through a special fingerprint recognition sensor. Wherein, the fingerprint recognition module is often arranged at the lower end outside the visible area of ​​the screen, or at the back of the electronic device. [0003] However, the current design method essentially has the following disadvantages: (1) It requires a structural space other than the screen to place the fingerprint...

Problems solved by technology

[0003] However, the current design method essentially has the following disadvantages: (1) It requires a structural space other than the screen to place the fingerprint identification module, which increases the difficulty of structural stacking of small electronic devices such as smart watches; (2) There are fingerprint recognition sensors that are local in electronic equipment and based on a small area, which is manifested as using a fingerprint recognition module smaller than a finger to realize fingerprint recognition

[0004] As people have higher and higher requirements for the appearance design and operation convenience of electronic equipment, the current design method limits the development of electronic equipment in the direction of smaller size and more convenient operation.
