Abstract: A fingerprint recognition device and a touch apparatus comprise a plurality of fingerprint recognition areas (100) with a rectangle shape arranged in a matrix. Each of the fingerprint recognition areas (100) comprises a plurality of mutually independent fingerprint recognition electrodes (110) arranged along a diagonal direction of the fingerprint recognition area (100). Arrangement directions of the fingerprint recognition electrodes (110) in the respective fingerprint recognition areas (100) are same. Because the fingerprint recognition electrodes (110) in the respective fingerprint recognition areas (100) are arranged in a same diagonal direction, the fingerprint recognition electrodes (110) belonging to a same or adjacent fingerprint recognition area(s) (100) can detect full fingerprint information when a finger slides on the fingerprint recognition device in any one of a plurality of directions, so that the fingerprint is recognized. The sliding type fingerprint recognition device is not restricted by the sliding direction of the finger, and thus an application scope of the sliding type fingerprint recognition device can be expanded.

Abstract: The present invention provides a gate driving circuit and a driving method thereof, a display device, which relates to the field of display technology. The gate driving circuit may comprise a plurality of mutually cascaded shift register units and a pre-charging unit, the gate row drive scanning and touch control scanning of the plurality of mutually cascaded shift register units are performed alternately. By additionally arranging a pre-charging unit connected with the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished, the first stage of shift register unit can be pre-charged during the touch control scanning. In this way, the electric leakage phenomenon of the pull-up control node (PU point) of the corresponding first stage of shift register unit when the gate row drive scanning is performed again after the touch control scanning is accomplished due to a relatively long touch control scanning time interval between outputs of two rows of shift register units is avoided, thereby avoiding the defect of insufficient charging rate of row of pixels while ensuring touch control scanning of high report rate.
