Abstract

The invention discloses a fingerprint identification module driving method and a display device, wherein the driving method and the display device relate to the field of displaying technology. The fingerprint identification module comprises a plurality of fingerprint scanning lines, a plurality of fingerprint signal lines, a plurality of fingerprint identification units and a fingerprint identification driving circuit. The fingerprint identification units in one line are electrically connected the same fingerprint scanning line. The driving method at least comprises a first working period in which the fingerprint identification driving unit supplies a scanning driving signal to at least two fingerprint scanning lines each time in the extending direction of the fingerprint signal line. Furthermore at least four fingerprint scanning lines which are driven to perform scanning in two adjacent times at least comprise the same fingerprint scanning line. According to the driving method and the display device, through an overlapping type scanning driving mode in the same scanning period, an effect of connecting the fingerprint identification units which perform repeated scanning is realized, and the area of the fingerprint identification unit is enlarged, thereby increasing the signal amount of the fingerprint identification unit and improving accuracy and detecting effect in fingerprint identification.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a driving method and a display device for a fingerprint recognition module. Background technique [0002] Fingerprints are the lines formed by the bumpy skin at the end of human fingers, also called palm prints, which are the raised lines on the epidermis. Since human fingerprints are a combination of genetics and the environment, they are also closely related to human health. Therefore, everyone has fingerprints, but they are different. Because the repetition rate of fingerprints is extremely small, it is called "human ID card". Display devices with fingerprint recognition functions, such as mobile phones, tablet computers, and smart wearable devices. The display device with integrated fingerprint recognition function, when the user uses the display device, can use the fingerprint recognition function to make the display device perform a specific function. ...
