The invention discloses a fingerprint identification device, a touch panel and a display device. The fingerprint identification device includes a plurality of first driving lines and a plurality of first sensing lines, the first driving lines extend along a first predetermined direction, and the first sensing lines extend along a direction not parallel to the first predetermined direction. The plurality of first sensing lines are divided into at least two sensing groups along the first predetermined direction, and each of the sensing groups includes A plurality of sub-sensing groups are provided, each sub-sensing group includes at least one first sensing line, and adjacent sub-sensing groups are insulated from each other. The present invention optimizes the design pattern of the first driving line and the first sensing line in the fingerprint identification device, so that each first driving line can obtain more fingerprint data when scanning, effectively shortening the time for fingerprint detection, and being able to Faster and faster fingerprinting.
Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a fingerprint identification device, a touch panel including the fingerprint identification device, and a display device including the touch panel. Background technique [0002] The fingerprint touch function is currently mainly realized through capacitive sensing technology. Capacitive sensing technology is mainly divided into two types, one is push type and the other is scratch type. Compared with the push-type sensor with a larger surface area, the scratch-type sensor has the advantages of small surface area and volume, and low power consumption. [0003] When the scratch sensor collects fingerprints, the area where the finger slides is sampled at a high sampling rate to obtain a set of fingerprint data. By splicing these fingerprint data, a complete fingerprint image can be obtained. In the prior art, the process of collecting fingerprint data is relatively cumbersom...
