Abstract

The embodiment of the invention discloses a sliding fingerprint identification method, an array substrate, a display panel and a display device. The fingerprint identification method comprises the following steps: when a finger touches the array substrate, determining an area covered by a current finger; Dividing an area covered by the current finger into at least two sub-areas, the at least two sub-areas being arranged in sequence along a column direction of the first array structure; At least one row of that fingerprint identification unit is selected as a reference row in each of the sub-regions; starting the fingerprint identification unit located in each of the reference rows; recording a fingerprint identification signal of each of the fingerprint identification units in each of thereference rows in a time period from t1 to t2, t1 < lt; t2; Obtaining fingerprint information based on a fingerprint identification signal of each of the fingerprint identification units in each of the reference rows in a time period from t1 to t2 to reduce power consumption of the display panel.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a sliding fingerprint identification method, an array substrate, a display panel and a display device. Background technique [0002] Each person's skin texture, including fingerprints, varies in patterns, breakpoints, and intersections, which are unique and remain unchanged throughout life. Accordingly, we can match a person with his fingerprint, and verify his real identity by comparing his fingerprint with the pre-saved fingerprint data. This is fingerprint recognition technology. Thanks to electronic integrated manufacturing technology and fast and reliable algorithm research, optical fingerprint recognition technology in fingerprint recognition technology has begun to enter our daily life, and has become the most in-depth research, the most widely used and the most mature in biometrics. technology. [0003] At present, the fingerprint identification techn...
