Abstract
The fingerprint recognition panel includes fingerprint recognition circuits arranged in a matrix, reading signal lines, a gate driving circuit and scanning lines connected with the gate driving circuit. The gate driving circuit is for outputting scanning signals to the scanning lines successively; each fingerprint recognition circuit is in connection with two scanning lines, a reading control end is connected with a first scanning line, and a reset control end is connected with a second scanning line; the first scanning line in connection with the fingerprint recognition circuits of the nth row and the second scanning line in connection with the fingerprint recognition circuits of the (n−m)th row are the same; or the second scanning line in connection with the fingerprint recognition circuits of the nth row and the first scanning line in connection with the fingerprint recognition circuits of the (n−m)th row are the same.
