Abstract: The present disclosure provide a touch display driving method, a touch display driving apparatus and the touch display screen for reducing a touch noise. The touch display driving method comprises: in a display scanning period, implementing a display scanning operation on a display scanning region including multiple display scanning lines; in a touch scanning period, when there is an overlap between a touch scanning region corresponding to a current touch driving line and the display scanning region, skipping the touch scanning region which overlaps with the display scanning region, to implement a touch scanning operation on a touch scanning region corresponding to any touch driving line after the current touch driving line; and in a next touch scanning period, returning to implement a touch scanning operation on the touch scanning region which overlaps with the display scanning region. This effectively avoids an overlap between a touch scanning region and a display scanning region at a certain time, so as to thoroughly solve the problem that a touch noise occurs.

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.
