The protective layer and the functional film layer are at the same side of the array substrate. The protective layer includes a first bending portion arranged adjacent to the functional film layer, and a second bending portion connected to a side of the first bending portion away from the functional film layer. A distance between an edge of the second bending portion away from the first bending portion and the functional film layer in a first direction perpendicular to an interface between the display portion and the bending portion is the largest in the protective layer.

Provided are a display panel and a manufacturing method thereof, and a display device. The display panel includes: a base substrate including a display area and a peripheral area; sub-pixels located, at least one sub-pixel including a driving transistor including conductive layers; a first dam located at the peripheral area; a second dam located at the peripheral area and located on one side of the first dam away from the display area; an encapsulation layer, orthographic projections of the sub-pixels, the first and the second dam on the base substrate being located within that of the encapsulation layer; and at least one pressure sensor located on at least one of a first side of the second dam proximate to the first dam or a second side away from the first dam, wherein at least one resistor in each pressure sensor is located in a same layer as one conductive layer.

The present application relates to the technical field of display, and discloses a display panel, a preparation method therefor, and a display apparatus. The material of a filter film layer in the display panel comprises a conductive material, so the filter film layer may be used as a detection plate of a fingerprint identification circuit. Moreover, since the filter film layer is located on the side of a display function film layer away from a base substrate, the filter film layer is far away from a signal line in the display function film layer, and is not easily affected by the signal line. When the filter film layer is used as the detection plate, the signal-to-noise ratio of a fingerprint signal detected by the fingerprint identification circuit may be larger, and the fingerprint identification effect may be better. Moreover, when the filter film layer is used as the detection plate, the distance between the filter film layer and an obstacle relative to the display function film layer is relatively short. Therefore, the signal detected by the fingerprint identification circuit may be made larger, thereby ensuring the fingerprint identification effect.
