    摘要: A display panel and a display device are provided. The display panel includes: a primary contour defining an active display region and including first portions extending non-linearly, a secondary contour inside the primary contour and including second portions extending non-linearly; the primary contour is an outer contour after the display panel is lightened; pixels in the active display region include pixels of first type inside the secondary contour, pixels of second type intersecting the second portion, and pixels of third type intersecting the first portion and outside the secondary contour; an aperture ratio of pixels of third type is smaller than that of pixels of first type, an aperture ratio of at least part of pixels of second type is positively correlated with an area of a part, inside the secondary contour, of each pixel of second type.

    摘要: 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.
